This Croissant Breakfast Casserole is a fluffy and tasty way to start your day! With soft croissants, eggs, cheese, and your favorite veggies, it’s like breakfast in one big dish!
Honestly, who can resist a warm, cheesy casserole? It’s perfect for family brunches or lazy weekend mornings. I love making it the night before—just pop it in the oven in the morning!
Key Ingredients & Substitutions
Croissants: The star of this dish! Fresh croissants bring a buttery, flaky texture. If you don’t have croissants, you can use stale French bread or even bagels for a different twist.
Eggs: Fresh large eggs are essential for binding everything together. If you’re looking for a lighter alternative, consider using egg whites or a plant-based egg substitute.
Cheese: Cheddar is a delightful choice for its strong flavor. If you’re not a fan, feel free to swap it for mozzarella, Monterey Jack, or even feta for a tangy bite.
Bacon: Cooked bacon adds a savory crunch. For a healthier option, turkey bacon or diced ham works well. Or, you can skip the meat entirely for a vegetarian version!
Green onions: They add freshness and a mild flavor. Chives make a great substitute, or even toss in a handful of spinach or bell peppers for a veggie boost.
How Do I Get the Perfect Texture in the Casserole?
To achieve that dreamy, fluffy texture, make sure to let the croissants absorb the egg mixture well. When you pour the egg over, gently press down the croissant pieces with a spoon. This helps them soak it up fully.
- Letting the casserole rest for at least 10 minutes before baking also helps—this relaxes the croissants and enhances the final dish.
- Keep an eye on the oven! Every oven is different, so check around the 35-minute mark. You want the top golden brown and set in the middle.
With these tips, your Croissant Breakfast Casserole will come out perfectly delicious every time! Enjoy your breakfast!
Croissant Breakfast Casserole
Ingredients You’ll Need:
Main Ingredients:
- 6 large croissants, torn into large pieces
- 8 large eggs
- 2 cups whole milk
- 1 cup shredded cheddar cheese (or cheese of your choice)
- 6 slices cooked bacon, chopped
- 1/2 cup chopped green onions (plus extra for garnish)
Seasonings:
- Salt, to taste
- Black pepper, to taste
- Optional: 1 tsp Dijon mustard or garlic powder for extra flavor
How Much Time Will You Need?
This delicious casserole takes about 15 minutes to prepare and then 35-45 minutes to bake in the oven. Plus, it only needs about 5 minutes to cool before serving. That means you’ll be just about an hour away from a comforting, warm breakfast that everyone will enjoy!
Step-by-Step Instructions:
1. Preheat Your Oven:
Start by preheating your oven to 350°F (175°C). Greasing a 9×13-inch baking dish is important, so that nothing sticks when it’s time to serve.
2. Prepare the Croissants:
Tear the croissants into large chunks. Spread these evenly across the bottom of the prepared baking dish, creating a nice base for your casserole.
3. Add the Toppings:
Sprinkle your shredded cheese, chopped bacon, and 1/2 cup of green onions over the croissant pieces. This adds a delicious mix of flavors!
4. Mix the Egg Mixture:
In a large bowl, whisk together the eggs, whole milk, salt, pepper, and any optional seasonings until everything is well combined and a bit frothy.
5. Combine Everything:
Carefully pour your egg mixture evenly over the croissants and toppings in the baking dish. Make sure it covers everything nicely!
6. Ensure Soaking:
Using a spoon or spatula, gently press the croissant pieces down to help them soak up the egg mixture. This helps to create that soft, custardy texture inside!
7. Bake to Perfection:
Bake uncovered for about 35-45 minutes. You’ll know it’s ready when it’s set and the top is golden brown. If you’re waiting for that extra flair, you can gently crack a couple of eggs on the surface halfway through to create a lovely baked-top effect.
8. Garnish and Cool:
Once baked, take your casserole out and sprinkle some additional chopped green onions on top for a beautiful finish. Let it cool for about 5 minutes before serving.
9. Serve and Enjoy!
This croissant breakfast casserole is a wonderful dish for a family breakfast or brunch. Enjoy the crispy top and deliciously soft inside, rich with eggs, cheese, and bacon. Happy eating!
Can I Use Day-Old Croissants for This Recipe?
Absolutely! Day-old croissants work great because they are slightly drier, allowing them to soak up more of the egg mixture without becoming mushy. If they’re too stale, just give them a quick toast before using.
Can I Make This Breakfast Casserole Ahead of Time?
Yes! You can assemble the casserole the night before and store it covered in the fridge. In the morning, just pop it in the oven straight from the fridge—though you might need to add an extra 5-10 minutes to the baking time.
How Should I Store Leftovers?
If you have any leftovers, store them in an airtight container in the fridge for up to 3 days. To reheat, simply place portions in the microwave or warm them in the oven until heated through.
What Are Some Good Add-Ins or Variations for This Casserole?
Feel free to get creative! Add sautéed mushrooms, spinach, or bell peppers for extra veggies. If you’re a fan of spicy food, adding jalapeños or pepper jack cheese can give it a nice kick!
