Tips for the Perfect Croissant Breakfast Casserole

1. Use Day-Old Croissants

   • Slightly stale croissants soak up the egg mixture better without getting mushy. If your croissants are fresh, toast them lightly in the oven for 5-10 minutes at 300°F.

2. Cook the Bacon Crispy

   • Crispy bacon adds a nice texture contrast. Cook it until golden and drain on paper towels to remove excess grease.

3. Balance Your Cheese

   • Use a mix of sharp cheddar for flavor and mozzarella for that irresistible meltiness. Avoid using only mozzarella, as it’s mild and needs the cheddar to add depth.

4. Soak the Croissants Well

   • Gently press the croissants into the egg mixture after pouring it over. This ensures every piece soaks up flavor without drying out.

5. Don’t Skip Rest Time

   • Let the assembled casserole sit for 10-15 minutes before baking. This allows the croissants to fully absorb the custard for a soft yet firm texture.

6. Cover, Then Uncover

   • Bake the casserole covered with foil for the first 20 minutes to avoid over-browning. Uncover it for the last 15 minutes to get a golden, crispy top.

7. Flavor Boosters

   • Add a pinch of garlic powder, black pepper, or a sprinkle of fresh herbs (like parsley) after baking for extra flavor.

8. Prep Ahead

   • Assemble the casserole the night before, cover, and refrigerate. Bake it in the morning for a stress-free breakfast.
