Choosing the Right Bread

Best Breads for Breakfast Casseroles

The foundation of any great breakfast casserole with bread is, well, the bread! While you can use almost any type, some work better than others. French bread and sourdough offer sturdy structures that hold up well to soaking without becoming mushy. Brioche and challah add richness and a subtle sweetness to your casserole. Day-old bread is preferable as it absorbs the egg mixture better without falling apart.

Bread Preparation Tips

For the best breakfast casserole with bread, cut bread into 1-inch cubes and let them sit out for 1-2 hours (or overnight) to become slightly stale. This drying process helps the bread absorb the egg mixture without becoming soggy. If you’re in a hurry, spread bread cubes on a baking sheet and toast at 300°F for 10-15 minutes until lightly dried but not browned.

Substitutions

No French bread on hand? No problem! English muffins, hamburger buns, or even croissants can work wonderfully in breakfast casseroles with bread. Whole grain bread adds fiber and a nutty flavor for a healthier twist. Gluten-free bread works, too—just make sure it’s slightly toasted first to improve its structure in the final casserole.

Ingredients & Prep

Breakfast Casserole Essentials

• Bread (6-8 cups cubed): The base that gives structure to your breakfast casserole
• Eggs (8-12 large): The binding agent that brings everything together
• Milk (2-3 cups): Creates custard-like texture when combined with eggs
• Cheese (1-2 cups shredded): Adds richness and flavor throughout
• Seasonings: Salt, pepper, garlic powder, onion powder, and herbs of choice
• Mix-ins: Breakfast meats, vegetables, and additional flavor enhancers

Make-Ahead Preparation

The beauty of breakfast casseroles with bread is their make-ahead potential. Assemble your casserole the night before, cover it with plastic wrap, and refrigerate overnight. The resting period allows the bread to fully absorb the egg mixture, resulting in a more uniform texture and deeper flavor development. In the morning, simply remove from the refrigerator while your oven preheats, then bake until golden and set.

Base Egg Mixture

For a standard 9×13 bread breakfast casserole:

• 10-12 large eggs
• 2-2½ cups milk or half-and-half
• 1 teaspoon salt
• ½ teaspoon black pepper
• Optional: ½ teaspoon each of garlic powder, onion powder, and dried herbs

Whisk until well combined and pour over your bread and other fillings.

Step-by-Step Cooking Instructions

Pre-Cooking Prep

1. Grease a 9×13-inch baking dish with butter or cooking spray
2. Spread bread cubes evenly in the prepared dish
3. Layer in your proteins, vegetables, and about half the cheese
4. Pour the egg mixture evenly over all ingredients, pressing the bread down gently to ensure absorption
5. Sprinkle the remaining cheese on top of your breakfast casserole with bread
6. Cover and refrigerate for at least 30 minutes or overnight

Baking Method

1. Preheat oven to 350°F (175°C)
2. If refrigerated overnight, let the casserole sit at room temperature for 20-30 minutes
3. Bake uncovered for 45-55 minutes until the center is set and the top is golden brown
4. If the top browns too quickly, cover loosely with foil halfway through the baking

Doneness Check

Your breakfast casserole with bread is done when:

• The center is set and doesn’t jiggle when you gently shake the dish
• A knife inserted in the center comes out clean (may have melted cheese but no raw egg)
• The internal temperature reaches 160°F on an instant-read thermometer
• Edges are golden brown and slightly pulling away from the sides of the dish

Resting Period

Allow your casserole to rest for 10-15 minutes before serving. This resting period helps the breakfast casserole set up properly for cleaner slices and allows the flavors to meld together.

Pro Tips for Perfect Breakfast Casseroles

Avoiding Soggy Casseroles

• Use day-old or toasted bread for better absorption in your breakfast casserole
• Don’t oversoak—bread should be moist but not swimming in liquid
• Layer ingredients properly with bread on the bottom to create a solid base
• For extra insurance against sogginess, sprinkle a thin layer of shredded cheese on the bottom of your baking dish before adding bread

Kitchen Tool Recommendations

• Glass or ceramic 9×13 baking dish for even heating
• Whisk for thoroughly combining eggs and milk
• Large mixing bowl for tossing bread with add-ins
• Instant-read thermometer for checking the doneness of your breakfast casserole with bread
• Sharp serrated knife for clean slices when serving

Storage & Reheating

• Refrigerate leftover casserole within two hours of baking
• Store in airtight containers for up to 4 days
• Reheat individual portions in the microwave for 1-2 minutes
• For best texture when reheating a larger portion, cover with foil and warm in a 325°F oven until heated through (about 20 minutes)
• Freeze-baked breakfast casserole in individual portions for up to 2 months

FAQs

Can I use frozen bread in my breakfast casserole?

While fresh or day-old bread is ideal, you can use frozen bread in a pinch. Thaw completely and toast lightly before using to remove excess moisture for the best texture in your breakfast casserole.

How do I fix an undercooked breakfast casserole with bread?

If the top is golden but the center is still jiggly, cover with foil and continue baking in 10-minute increments until set. For future casseroles, ensure your oven is properly calibrated and consider using a slightly lower temperature for a longer baking time.

Can I make a dairy-free breakfast casserole with bread?

Absolutely! Substitute regular milk with unsweetened almond, soy, or oat milk. Use dairy-free cheese alternatives or simply increase the vegetables and seasonings for flavor in your breakfast casserole.

Is breakfast casserole safe for pregnant women?

Yes, as long as it’s cooked to the proper temperature (160°F) and any meat ingredients are fully cooked before adding to the casserole. When in doubt, use a food thermometer to check the doneness of your breakfast casserole with bread.

Can I halve the recipe for a smaller household?

Yes! Use an 8×8 or 9×9 square baking dish, reduce the ingredients by half, and check for doneness about 10 minutes earlier than the full recipe suggests.
