Prepare the Casserole Dish: Grease a 9x13x2-inch casserole dish with cooking spray or butter to prevent sticking.
Cook the Sausage: In a large skillet, cook 1 pound of pork sausage over medium-high heat. Stir frequently until thoroughly cooked and no longer pink (about 5-7 minutes). Drain excess fat and set aside.
Whisk the Egg Mixture: In a large bowl, whisk together 10 large eggs, 3 cups of milk, 1 teaspoon of fine sea salt, and ½ teaspoon of black pepper until well combined.
Layer the Ingredients: Evenly distribute half the 6 cups of cubed bread into the prepared casserole dish. Sprinkle with half of the 2 cups of shredded sharp cheddar cheese, half of the cooked sausage, and half of the diced red pepper if using. Repeat the layers.
Pour the Egg Mixture: Pour the egg mixture evenly over the layers in the casserole dish, ensuring it saturates all the bread.
Rest or Bake: Cover the casserole and refrigerate overnight for the best flavor. Or, you can bake it immediately if time is short.
Bake the Casserole: When ready to bake, preheat your oven to 325°F. Bake uncovered for 60-75 minutes, or until the eggs are set. If the top begins to brown too much, loosely cover the dish with foil.
Garnish and Serve: If desired, sprinkle with sliced green onions. Serve warm, and watch it disappear from the table!

Storing & Reheating

This breakfast casserole can be stored in an airtight container in the refrigerator for up to 3 days. To extend its life, it can also be frozen for up to 3 months. Simply wrap it tightly with plastic wrap and foil before freezing. When you’re ready to enjoy, reheat in the oven at 350°F until heated through, about 25-30 minutes, to maintain texture and flavor. Expect a slight change in texture after freezing, but it will still be delicious!

Chef’s Helpful Tips

Be sure to use stale bread for a better texture as it soaks up the egg mixture more effectively without getting too mushy.
For maximum flavor, allow the casserole to rest overnight in the fridge; this melds the ingredients beautifully.
Check the casserole a little early while baking—ovens can vary in temperature!
If you prefer a creamier casserole, you can add a splash of heavy cream to the egg mixture.
Consider adding crumbled bacon or vegetables like spinach for an added flavor boost.

With its comforting flavors and warm aroma, this breakfast casserole offers everything you want in a brunch dish. It’s easy to prepare, satisfying, and creates wonderful memories shared with loved ones as you enjoy this meal together. Don’t hesitate to try new variations or ingredients; every twist can lead to a delightful discovery. I hope you love creating this dish as much as I do, and I can’t wait for you to share it with your family. Enjoy every bite!

Recipe FAQs

Can I make this breakfast casserole vegetarian?

How do I know when the casserole is done baking?

The casserole is done when the eggs are set and no longer jiggly, and a knife inserted in the center comes out clean. It should turn a lovely golden color on top.

Can I use different types of cheese?

Definitely! Feel free to mix and match cheeses according to your preferences. Gouda, mozzarella, or pepper jack can all lend unique flavors and textures to the casserole.

Is this casserole suitable for freezing?

Yes, it’s great for freezing! Just allow it to cool completely before wrapping tightly and storing in the freezer. When you’re ready to serve, thaw it in the fridge overnight before baking.
