6 large eggs – the heart of your Croissant Breakfast Casserole; I always choose organic for richer flavor.
2 cups whole milk – to create a creamy custard that seeps into the croissants.
4 large croissants, torn into chunks – fresh, buttery croissants are a game-changer here.
1 cup shredded sharp cheddar cheese – adds that cheesy pull we all crave.
1/2 cup grated Gruyere cheese – for a nutty depth.
1/2 cup cooked breakfast sausage or bacon, chopped – brings that savory punch.
1 small onion, finely chopped – for a mild sweetness.
2 cloves garlic, minced – essential for a trace of warmth.
1 teaspoon Dijon mustard – a secret layer of tanginess that enriches the eggs.
1/2 teaspoon smoked paprika – my spice secret that adds mild smokiness.
Freshly ground black pepper, to taste
Salt, to taste
2 tablespoons fresh chives, chopped – brightens the dish with a fresh herb note.

For the best flavor in your Croissant Breakfast Casserole, I recommend sourcing croissants from a local bakery that uses real butter. Ditto for cheese – a quality sharp cheddar and Gruyere will lift this breakfast casserole with croissants from good to memorable. You’ll find the freshest ingredients for this recipe at farmer’s markets, where onions and herbs have more punch. If you want to keep it veggie-friendly, swap the meat for sautéed mushrooms and spinach. My family loves when I add that extra smoked paprika — it’s subtle but transforms the casserole’s profile.

1. Preheat your oven to 350°F. Lightly grease a 9×13 inch casserole dish. The oven temp is perfect for gently baking your Croissant Breakfast Casserole to set the eggs without drying out the croissants.

2. Tear your croissants into bite-sized chunks and spread evenly in your casserole dish. This layering lets each piece soak up the egg mixture.

3. In a skillet over medium heat, cook the chopped onion and garlic until softened and fragrant, about 3 minutes. Add your cooked sausage or bacon and stir together. This step pulls together savory flavor layers for your Croissant Breakfast Casserole.

4. Sprinkle the onion, garlic, and sausage mixture evenly over the croissant chunks. Then top with shredded cheddar and Gruyere cheeses. Trust me, these cheeses melt beautifully here.

5. In a large bowl, whisk together eggs, milk, Dijon mustard, smoked paprika, salt, and pepper until smooth. Pour evenly over your layers in the dish. You’ll notice your Croissant Breakfast Casserole start to look like a rich, inviting bake at this stage.

6. Let the casserole sit for about 15 minutes before baking. This wait time allows the croissants to absorb the egg mixture fully, creating that custardy texture everyone loves.

7. Place the dish in the preheated oven and bake for 45 to 50 minutes. You’ll want to see a set center with a golden top. A toothpick inserted should come out clean, but the casserole remains moist and tender.

8. When the aroma fills the kitchen, it’s your signal that the Croissant Breakfast Casserole is nearly ready. Let it cool for 10 minutes before serving. This resting time helps the dish hold together and flavors to settle beautifully.

9. Garnish with fresh chives for a pop of color and a gentle herb note. Slice up and serve warm with your favorite morning sides.

Does this Croissant Breakfast Casserole really satisfy hearty appetites?
Absolutely. The blend of croissants, eggs, cheese, and sausage creates a filling dish that hits all the comfort notes your family craves.

What if someone prefers milder flavors?
You can reduce the smoked paprika or omit the Dijon mustard without losing the casserole’s essence. The cheeses and croissants still do the heavy flavor lifting.

Can I prepare this Croissant Breakfast Casserole ahead for busy mornings?
Yes! Assemble it the night before, cover, and refrigerate. Let it come to room temperature about 30 minutes before baking. This makes mornings less hectic but keeps the dish fresh.

Is there a vegetarian option?
Swap the sausage or bacon for sautéed mushrooms, bell peppers, or spinach. The cheesy croissant breakfast casserole maintains its savory goodness.

How important are the cheeses?
Cheddar and Gruyere provide complementary flavors. Sharp cheddar brings tang, while Gruyere adds nutty richness. Together, they make this casserole sing.

Can gluten-free croissants work?
In theory, yes. The texture may differ, but gluten-free croissants can be torn and soaked as the base for an eggs and croissant bake.

What sides best complement this casserole?
Fresh fruit, light salads, or roasted vegetables work well and add balance to the cheesy richness.
