Ingredients
The beauty of a Breakfast Croissant Bake lies in its simple yet flavorful ingredients that come together to create something truly magical. Here’s what you’ll need to feed approximately 8-10 hungry family members:
For the Base:
- 8-10 large croissants, slightly stale or day-old
- 8 large eggs
- 2 cups whole milk
- 1 cup heavy cream
- 2 tablespoons pure maple syrup
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon freshly grated nutmeg
- 1/4 teaspoon salt
For the Fillings (Customizable):
- 1 pound breakfast sausage, cooked and crumbled
- 8 slices bacon, cooked and chopped
- 1 cup diced ham
- 2 cups shredded cheese (combination of cheddar and Gruyère works wonderfully)
- 1/2 cup diced red bell pepper
- 1/2 cup diced green bell pepper
- 1 small onion, finely diced and sautéed until translucent
Optional Garnishes:
- Fresh chopped chives
- Sliced green onions
- Extra maple syrup for drizzling
- Fresh berries for serving on the side
Feel free to adjust the protein options based on your family’s preferences. You might choose all sausage, all bacon, or a mixture as I’ve suggested. The same goes for the cheese – while I recommend cheddar and Gruyère for their melting properties and flavor, you can certainly use what you have on hand. The vegetables add color and nutrition, but can be modified based on what your family enjoys.

I’ve found that preparing this dish the evening before a special breakfast or brunch gathering is ideal. This allows the croissants to fully absorb the egg mixture, resulting in that perfect custardy texture we all love, while also making your morning routine stress-free. Just pop it in the oven while you’re enjoying your first cup of coffee, and by the time everyone is up and ready for breakfast, your magnificent creation will be golden, puffy, and ready to serve.
Instructions
Step-by-Step Instructions
Follow these detailed steps to create a Breakfast Croissant Bake that will have your family asking for seconds (and probably the recipe too)!
Step 1: Prepare Your Ingredients
Begin by cooking your breakfast meats if they aren’t already prepared. Brown and crumble the sausage in a skillet over medium heat until no longer pink (about 7-8 minutes). Cook the bacon until crispy, then drain on paper towels and crumble or chop. If using ham, dice it into small, bite-sized pieces. Sauté the diced onions until translucent (about 5 minutes), then add the bell peppers and cook for another 2-3 minutes until slightly softened.
Step 2: Prepare the Baking Dish
Generously butter a 9×13-inch baking dish to prevent sticking. This will also add an extra layer of rich flavor to the edges of your casserole.
Step 3: Prepare the Croissants
Tear or cut the croissants into large, bite-sized pieces (about 2-inch chunks). Day-old or slightly stale croissants work best as they’ll absorb the egg mixture without becoming too soggy. If your croissants are very fresh, you can tear them up and leave them out for a few hours or place them in a 300°F oven for about 10 minutes to dry them out slightly.
Step 4: Layer Your Ingredients
Place half of the croissant pieces in an even layer at the bottom of the prepared baking dish. Sprinkle with half of the cooked breakfast meats, sautéed vegetables, and cheese. Add the remaining croissant pieces on top, followed by the remaining meats, vegetables, and cheese.
Step 5: Prepare the Egg Mixture
In a large bowl, whisk together the eggs, milk, heavy cream, maple syrup, vanilla extract, cinnamon, nutmeg, and salt until well combined and slightly frothy.
Step 6: Combine Everything
Slowly and evenly pour the egg mixture over the layered ingredients in the baking dish. Use the back of a spoon or spatula to gently press down on the croissant pieces, ensuring they begin to absorb the liquid.
Step 7: Rest the Mixture
Cover the baking dish with plastic wrap and refrigerate for at least 2 hours, preferably overnight. This resting period is crucial for the croissants to fully soak up the egg mixture, resulting in a perfect texture once baked.
Step 8: Preheat and Prepare for Baking
When you’re ready to bake, preheat your oven to 350°F (175°C). Remove the baking dish from the refrigerator and let it sit at room temperature for about 30 minutes while the oven preheats. Remove the plastic wrap and cover the dish with aluminum foil.
Step 9: Bake the Casserole
Place the covered baking dish in the preheated oven and bake for 30 minutes. Then, remove the foil and continue baking for another 15-20 minutes, or until the top is golden brown and the center is set (it should no longer be liquid when gently pressed).
Step 10: Rest and Serve
Allow the Breakfast Croissant Bake to rest for 5-10 minutes before serving. This brief resting period helps the casserole set up nicely for cleaner serving. Garnish with fresh chives or sliced green onions if desired, and offer maple syrup on the side for those who enjoy a touch of sweetness.
The beauty of this family-style breakfast is watching everyone gather around, plates in hand, eager to enjoy this warm, comforting meal together. It’s these moments that make the simple act of cooking for those you love so incredibly rewarding.
Nutritional Information
While our Breakfast Croissant Bake is certainly a special treat rather than an everyday breakfast, understanding its nutritional profile can help you plan the rest of your day’s meals accordingly. The following information is an approximate per serving, assuming the recipe serves 10 people:
- Calories: Approximately 550-650 per serving
- Protein: 25-30g per serving
- Carbohydrates: 30-35g per serving
- Fat: 35-40g per serving
- Fiber: 1-2g per serving
- Sugar: 8-10g per serving
- Sodium: Approximately 800-900mg per serving
Keep in mind that these values can vary significantly based on the specific ingredients you choose. For example, using turkey sausage instead of pork, reducing the amount of cheese, or incorporating more vegetables will alter the nutritional profile.
This hearty breakfast casserole is rich in protein from the eggs and breakfast meats, which helps keep you satisfied throughout the morning. The croissants provide carbohydrates for energy, while the dairy components offer calcium and vitamin D.
While this isn’t a low-calorie dish, it’s perfect for special family gatherings where comfort and tradition take center stage. Balance it with fresh fruit on the side and perhaps a lighter dinner later in the day if you’re watching your caloric intake.
Healthier Alternatives
Our family traditions evolve over time, and I’ve found ways to adjust our beloved Breakfast Croissant Bake to accommodate various dietary preferences while still maintaining that special homey quality we all love. Here are some healthier alternatives you might consider:
Lighter Dairy Options:
- Substitute whole milk with 2% or skim milk
- Replace heavy cream with half-and-half or more milk
- Use reduced-fat cheese or reduce the overall amount
- Try Greek yogurt in place of some of the milk for added protein
Leaner Protein Choices:
- Use turkey bacon instead of pork bacon
- Substitute turkey or chicken sausage for pork sausage
- Try Canadian bacon, which is leaner than traditional ham
- Add extra egg whites to increase protein while reducing fat
More Vegetables:
- Double or triple the amount of bell peppers
- Add spinach, kale, or other leafy greens
- Include diced tomatoes, mushrooms, or zucchini
- Try roasted sweet potatoes for added nutrition and natural sweetness
Bread Alternatives:
- Use whole grain croissants if available
- Try a mixture of croissants and whole grain bread for more fiber
- Reduce the amount of croissants and increase the egg mixture for a more frittata-like dish
Reduced Sugar:
- Skip the maple syrup in the egg mixture or use a sugar-free alternative
- Add natural sweetness with diced apples or pears
When my sister started watching her cholesterol, we began making a half-batch with these healthier modifications just for her. Now, many family members actually prefer this lighter version for everyday brunches, saving the traditional recipe for special holidays. It’s a wonderful way to honor our family tradition while adapting to changing health needs and preferences.

Table Setting:
I’ve found that serving this casserole on our special ceramic serving dish, passed down from my grandmother, adds to the feeling of tradition and celebration. For family gatherings, I like to set out cloth napkins and use our “good” dishes – these small touches make even a casual breakfast feel special and memorable.
During holiday mornings, we serve the Breakfast Croissant Bake buffet-style, allowing everyone to help themselves while we gather in the living room in our pajamas. For more formal brunches with friends, individual portions plated with a side of fresh fruit and a sprig of mint create an elegant presentation worthy of any special occasion.
Common Mistakes
Through years of making this family favorite, I’ve encountered (and learned from) several pitfalls. Here are the most common mistakes to avoid when preparing your Breakfast Croissant Bake:
Using Very Fresh Croissants
Fresh, soft croissants will become too soggy when soaked in the egg mixture. Day-old or slightly stale croissants work best as they hold their structure better. If you only have fresh ones, tear them up and leave them out for a few hours or toast them lightly in the oven to dry them out a bit.
Skipping the Resting Period
I once tried to rush this recipe when unexpected guests arrived, and the result was disappointing. The egg mixture hadn’t fully penetrated the croissants, leading to dry spots in some areas and overly soggy parts in others. Always allow at least 2 hours of resting time, preferably overnight.
Overcrowding the Baking Dish
It can be tempting to pack in extra ingredients, especially when feeding a crowd, but this can prevent proper cooking. The casserole needs some room to puff up and for the heat to circulate. Use a larger dish or prepare two smaller casseroles if needed.
Under-seasoning the Egg Mixture
The egg mixture needs proper seasoning or the final dish will taste bland. Don’t be shy with the salt, pepper, and aromatics like vanilla and cinnamon. Remember that the croissants themselves are quite buttery but not heavily seasoned.
Not Cooking the Vegetables First
Raw vegetables can release too much moisture during baking and make the casserole watery. Always sauté onions, peppers, and mushrooms before adding them to the dish. This also enhances their flavors and ensures they’re fully cooked.
Opening the Oven Too Often
Constantly checking on the casserole by opening the oven door causes temperature fluctuations that can lead to uneven cooking or falling. Trust the process and check only when necessary.
Serving Immediately After Baking
The first time I made this for a family gathering, I served it straight from the oven. It was too hot to eat comfortably and fell apart when served. Allowing it to rest for 5-10 minutes helps it set up and makes for neater portions.
Using Raw Meats Without Pre-cooking
Always fully cook sausage, bacon, and other meats before adding them to the casserole. This ensures food safety and proper texture in the final dish.
My aunt once learned this lesson the hard way when she added raw sausage directly to the dish, resulting in a greasy casserole with undercooked meat. We still tease her about it at family gatherings!
Storage Tips
One of the many reasons our family loves this Breakfast Croissant Bake is its versatility, not just in preparation but also in storage and reheating. Here’s how to handle leftovers (though in our family, leftovers are rare!):
Refrigeration:
- Allow any leftover casserole to cool completely before refrigerating
- Cover the baking dish tightly with plastic wrap or aluminum foil
- Alternatively, transfer portions to airtight containers
- Refrigerate for up to 3-4 days
Freezing:
- For individual servings: Cool completely, then cut into portions
- Wrap each portion in plastic wrap, then aluminum foil
- Place wrapped portions in a freezer-safe bag or container
- For freezing an entire casserole: Bake as directed, cool completely, then cover tightly with plastic wrap and aluminum foil
- Label with the date and contents
- Freeze for up to 2 months
Reheating from Refrigerated:
- Individual portions: Microwave on 50% power for 1-2 minutes, then full power for another 30 seconds until heated through
- Whole casserole: Cover with foil and heat in a 325°F oven for about 20 minutes, or until the center reaches 165°F
Reheating from Frozen:
- Individual portions: Microwave on 50% power for 3-4 minutes, checking and rotating halfway through, then heat on full power in 30-second increments until hot
- Whole casserole: Thaw overnight in the refrigerator, then reheat as above
- Alternatively, reheat from frozen by covering with foil and baking at 325°F for 45-60 minutes, removing the foil for the last 10 minutes
Make-Ahead Tips:
When I’m hosting a large family gathering, I often prepare multiple casseroles in advance. You can assemble the entire casserole up to 24 hours before baking, keep it covered in the refrigerator, and then bake as directed when ready. This works wonderfully for holiday mornings or when guests are staying over.
My mother-in-law taught me a clever trick: prepare the egg mixture and store it separately from the assembled croissants, meats, and cheese. Combine them the night before baking for the freshest result while still saving prep time in the morning.
Conclusion
The Breakfast Croissant Bake has become more than just a recipe in our family—it’s a vessel for memories, traditions, and the simple joy of gathering around the table together. From sleepy Christmas mornings to celebrating graduations and birthdays, this versatile dish has been there for countless special moments in our lives.
What makes this breakfast casserole so special isn’t just its delicious combination of buttery croissants, savory fillings, and custard-like egg mixture—though those certainly don’t hurt! It’s the way it brings everyone together, creating those precious moments of connection that become the foundation of family traditions.
I love how this recipe has evolved over the years to accommodate changing dietary needs and preferences while maintaining its core comfort and appeal. It reminds me that family traditions don’t have to be rigid; they can grow and adapt just as our families do.
Perhaps my favorite aspect of this Breakfast Croissant Bake is how it allows the cook to actually enjoy the morning alongside everyone else. With most of the preparation done the night before, there’s no need to miss out on those precious morning moments together.
As you create your own version of this beloved casserole, I hope it brings the same warmth and joy to your household that it has to mine. Maybe you’ll add your own special ingredients or serving traditions that make it uniquely yours. That’s the beauty of family recipes—they grow and change with each generation while keeping us connected to those who shared them with us.
So from my family to yours, I wish you many delightful mornings gathered around this Breakfast Croissant Bake, creating memories that will last far longer than the casserole itself (which, let’s be honest, will probably disappear quickly!).
FAQs
Can I make this Breakfast Croissant Bake with regular bread instead of croissants?
Yes, though the texture and flavor will be different. If using regular bread, choose a heartier variety like brioche, challah, or sourdough for best results. You may need to adjust the amount of liquid slightly as bread typically doesn’t absorb as much as croissants. The buttery flavor of croissants adds a special touch, but a bread version can still be delicious for everyday breakfasts.
Can I prepare this casserole the same morning I plan to serve it?
While the casserole is best when allowed to rest overnight, you can make a quicker version if necessary. Allow at least 30 minutes for the croissants to soak in the egg mixture before baking. To help speed up the absorption, warm the milk mixture slightly (not hot) and press the croissants gently into the liquid several times. The texture won’t be quite as perfect, but it will still be tasty in a pinch!
My family doesn’t eat pork. What protein alternatives would work well?
There are many wonderful alternatives! Try using turkey bacon or turkey sausage for similar flavors with less fat. For non-meat options, sautéed mushrooms provide a satisfying umami flavor, or try adding black beans and corn for a southwestern twist. You can also increase the cheese content or add plant-based protein crumbles if preferred. The egg base provides plenty of protein as well, so you could simply increase the vegetable content and skip the meat altogether.
Can this recipe be made gluten-free?
Absolutely! Look for gluten-free croissants at specialty bakeries or grocers (they’re becoming more widely available). If you can’t find gluten-free croissants, use gluten-free bread instead. Just ensure all other ingredients, including sausage and any seasonings, are also certified gluten-free. The basic egg mixture is naturally gluten-free. My cousin with celiac disease says this adaptation is one of her favorite special breakfasts.
Why is my casserole soggy in the middle even after the recommended baking time?
Several factors could cause this. First, check your oven temperature with an oven thermometer to ensure it’s accurate. Second, the dish might be too deep—using a wider, shallower dish allows for more even cooking. Third, the ratio of liquid to croissants might be off; if your croissants are smaller, reduce the egg mixture slightly. Finally, the casserole needs to rest after baking to fully set. If all else fails, you can return it to the oven for an additional 10-15 minutes at 325°F with foil covering just the edges to prevent over-browning.
