Cheesy Egg and Bacon Breakfast Bake

Pro tips

• Use day-old brioche to prevent the casserole from becoming soggy; fresh bread absorbs too much liquid.
• Cook the bacon until crispy and crumble it finely so it distributes evenly throughout the dish.
• Reserve ½ cup of shredded cheese to sprinkle on top just before baking for a golden, crusty surface.
• Let the assembled casserole sit in the refrigerator for at least 30 minutes (or overnight) so the bread fully absorbs the egg mixture.

Substitutions

• Brioise bread → challah, Texas toast, or croissants (adjust for richness)
• Cheddar cheese → Gruyère, Swiss, or fontina (maintains melting quality)
• Milk → half-and-half or heavy cream (richer custard)
• Bacon → sausage, ham, or smoked turkey (same amount, cooked and crumbled)

Storage & make-ahead

Cover and refrigerate leftovers up to 3 days; reheat covered at 350°F for 15 minutes. Assemble unbaked up to 12 hours ahead and refrigerate.

Can I make this breakfast bake the night before?

Yes. Assemble the casserole in the baking dish, cover, and refrigerate up to 12 hours. Add 5–10 minutes to baking time if baking from cold.

What bread works best for this recipe?

Brioche or challah works well because they're rich and absorb the egg custard evenly. Day-old bread prevents the casserole from becoming soggy.

Can I substitute the cheddar cheese?

Yes. Gruyère, Swiss, or a mix of cheddar and mozzarella all work well. Use the same total amount.

How do I know when the breakfast bake is done?

It's done when the center is set but still slightly jiggly in the very middle, and the top is golden brown—about 35–40 minutes at 350°F.

Can I freeze leftovers?

Yes. Cool completely, wrap tightly, and freeze up to 2 months. Reheat covered at 350°F for 20–25 minutes.
