🥐 Ingredients for Croissant Breakfast Casserole

This recipe uses simple ingredients that work together effortlessly.
Nothing fancy. Nothing complicated. Just comforting flavors that feel special.

You’ll need:

• Flaky croissants, torn into large pieces
• Eggs
• Milk or half-and-half
• Shredded cheese
• Cooked breakfast sausage or bacon (optional)
• Onion, diced
• Bell pepper, diced
• Salt and black pepper
• Fresh herbs like parsley or chives

Croissants are the star here.
Their buttery layers soak up the egg mixture while still keeping structure, giving this breakfast casserole its signature texture.

If your croissants are slightly stale, even better — they absorb more flavor and bake beautifully.

🍳 How to Make Croissant Breakfast Casserole

Start by setting the stage.
Preheat your oven to 350°F and lightly grease a large casserole dish. This ensures easy serving later.

Prepare the croissants.
Tear them into generous, uneven pieces and spread them loosely across the dish. Avoid pressing them down — air pockets help create a light, fluffy bake.

Mix the base.
In a bowl, whisk eggs with milk, salt, and pepper until smooth. This mixture transforms flaky croissants into a soft, custardy baked breakfast.

Build the layers.
Scatter sausage or bacon, onion, bell pepper, and half the cheese over the croissants. Pour the egg mixture evenly on top.

Let it soak.
Gently press down so the croissants absorb the liquid without collapsing.

Finish strong.
Add the remaining cheese, then bake until golden on top and set in the center. Let it rest briefly before slicing for clean, beautiful servings.
