Ingredients

• 1 pound breakfast sausage (pork or turkey, mild or spicy)
• 8 large eggs
• 2 cups whole milk (or half-and-half for extra richness)
• 4 cups cubed bread (day-old white or sourdough works best)
• 2 cups shredded cheddar cheese
• 1/2 teaspoon salt
• 1/2 teaspoon black pepper
• 1/4 teaspoon garlic powder
• 1/4 teaspoon onion powder
• Cooking spray or butter for greasing the dish

Instructions

1. Preheat your oven to 350°F (175°C) and grease a 9×13 baking dish.
2. Cook the sausage in a skillet over medium heat until fully browned.
3. Drain excess fat and spread the sausage evenly in the baking dish.
4. Add the bread cubes on top of the sausage.
5. Sprinkle shredded cheddar cheese evenly over the bread layer.
6. Whisk eggs, milk, salt, pepper, garlic powder, and onion powder in a bowl.
7. Pour the egg mixture slowly over the casserole.
8. Press gently so the bread absorbs the liquid.
9. Cover with foil and bake for 30 minutes.
10. Remove foil and bake another 20–25 minutes until set and golden.
11. Rest for 10 minutes before slicing. Trust me—it’s worth the wait.

Why This Breakfast Casserole Always Works

I’ve tested plenty of casserole breakfast ideas, and this one stays undefeated. Why? Balance. The eggs stay fluffy, the sausage brings savory depth, and the bread gives structure without turning soggy. Ever cut into a casserole and end up with soup? Yeah…not here. This egg and sausage bake holds together beautifully.

Perfect for Crowds

Hosting brunch stresses people out for no reason. This brunch casserole recipe feeds a crowd with one dish. You don’t flip pancakes or babysit bacon. You bake once and relax. Isn’t that the whole point of brunch?

Make-Ahead Friendly

You can prep this as an overnight breakfast casserole. Assemble everything, cover it, and refrigerate overnight. Bake it in the morning and enjoy fresh comfort food without morning prep chaos. I’ve done this more times than I can count, and it never disappoints.

Variations

This classic breakfast casserole loves flexibility. You can tweak it without breaking it. Here are my favorite variations:

• Vegetarian Breakfast Casserole: Skip the sausage and add sautéed mushrooms, bell peppers, and spinach.
• Gluten-Free Breakfast Casserole: Use gluten-free bread or swap bread for roasted potatoes.
• Healthier Twist: Use turkey sausage, low-fat milk, and reduce cheese slightly.

Ever notice how one tweak makes it feel brand new? That’s why this dish stays on repeat in my kitchen.

Serving & Tips

Serve this hearty breakfast casserole with fresh fruit, simple green salad, or crispy hash browns. It pairs beautifully with coffee, tea, or a lazy morning mimosa if brunch vibes call your name. Serve it warm for that ultimate comfort food breakfast feel.

For storage, cover leftovers tightly and refrigerate for up to 4 days. You can also freeze slices individually for quick breakfasts. Reheat gently in the oven or microwave. Want cozy winter vibes? Add a pinch of smoked paprika on top before baking. That tiny touch makes the whole dish feel extra comforting :/

Final Thoughts

This Classic Sausage & Egg Breakfast Casserole never tries too hard, and that’s why it shines. I rely on it for holidays, weekends, and busy weeks alike. It feeds people well, tastes familiar, and keeps mornings calm. If breakfast comfort food had a personality, this dish would give you a pat on the back and offer more coffee.

FAQs

Can I make this breakfast casserole ahead of time?

Absolutely. Assemble it the night before, refrigerate, and bake in the morning. It’s one of the easiest make ahead breakfast casseroles I know.

Can I freeze this casserole?

Yes. Let it cool fully, slice it, and freeze individual portions. This makes it a perfect freezer friendly breakfast casserole for busy mornings.

What bread works best?

Day-old white bread or sourdough works best. Slightly stale bread absorbs the egg mixture without falling apart.

How do I know when it’s fully cooked?

The center should feel firm and no liquid should jiggle when you shake the pan gently. A knife inserted in the center should come out mostly clean.
