Tips for Making the Best Christmas Breakfast Casseroles

1. Prepare ingredients in advance. Cook sausage, bacon, and vegetables before assembling your casseroles.

2. Use slightly stale bread. Day-old bread absorbs egg custard better and helps French toast casseroles hold their texture.

3. Thaw frozen potatoes. Remove excess moisture from thawed hash browns to prevent a watery casserole.

4. Don’t overbake. Egg casseroles should be cooked until the center is set, not until they become dry.

5. Choose the right cheese. Cheddar, mozzarella, Monterey Jack, and Swiss cheese all work beautifully in breakfast casseroles.

6. Let casseroles rest. Allow savory egg casseroles to rest for 5–10 minutes before slicing.
