Key Ingredients & Substitutions
Eggs: They provide the base for the casserole. You could swap whole eggs for egg whites for a lighter version, or use a plant-based egg substitute if you’re looking for dairy-free options.
Milk: Whole milk gives richness to the dish, but you can use low-fat milk or unsweetened almond milk if that’s what you have on hand.
Bread: Regular white bread is fine, but you can use whole wheat or even sourdough for added flavor. Stale bread works best as it soaks up the egg mixture without getting mushy.
Sausage: Breakfast sausage adds great flavor. If you prefer a leaner option, turkey sausage is a good substitute. For vegetarians, try crumbled tofu or black beans!
Cheddar Cheese: Sharp cheddar gives a nice punch, but feel free to mix in mozzarella or pepper jack for a twist! Dairy-free cheese also works for a non-dairy version.
How Do You Ensure Your Casserole Sets Perfectly?
The key to a well-set breakfast casserole is understanding the right baking time and technique. Make sure your bread is soaked well in the egg mixture without becoming mushy. Here’s how to do it:
- After pouring the egg mixture over the bread, gently press down to ensure the bread absorbs it.
- Keep an eye on the baking time. It should be golden brown on top and set in the middle.
- If necessary, check for doneness by inserting a knife into the center. It should come out clean when done.
Let it cool for a few minutes before serving. This allows it to firm up, making it easier to cut into portions.

Country Breakfast Casserole
Ingredients You’ll Need:
Main Ingredients:
- 6 large eggs
- 2 cups milk
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 6 slices white bread, cubed (preferably slightly stale)
- 8 ounces breakfast sausage, cooked and crumbled
- 1 cup shredded cheddar cheese
- 1/4 cup chopped green onions (scallions)
Optional Ingredients:
- 1/2 cup cooked and crumbled bacon
Time Needed:
This comforting casserole requires about 15 minutes of prep time and takes 40-45 minutes to bake. Including cooling time, you’ll have this delicious dish ready to enjoy in about 1 hour!
Step-by-Step Instructions:
1. Preheat the Oven:
Begin by preheating your oven to 350°F (175°C). While the oven is warming up, get your ingredients ready and grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking.
2. Mix the Egg Mixture:
In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until they are perfectly combined. This mixture provides the base of the casserole and will help bind all the ingredients together.
3. Assemble the Casserole:
Evenly spread the cubed bread into the greased baking dish. Next, sprinkle the cooked and crumbled sausage over the bread. If you are using bacon, sprinkle it on now. Pour the egg mixture over the bread and sausage, taking care to gently press down the bread with a fork or spatula to ensure it absorbs the egg mixture.
4. Add the Cheese:
Sprinkle the shredded cheddar cheese generously over the entire top of the casserole. This melty layer adds delicious flavor and a nice golden crust when baked.
5. Bake the Casserole:
Place the baking dish in the preheated oven and bake uncovered for 40-45 minutes. Look for the top to turn golden brown, and make sure the casserole is set in the middle. A toothpick inserted should come out clean.
6. Cool and Serve:
Once baked, remove the casserole from the oven and let it cool for about 5 minutes. This resting time helps it firm up a bit, making it easier to serve. Before serving, garnish with the chopped green onions for a fresh touch.
7. Enjoy!
Dig in while it’s warm! This casserole pairs perfectly with a side of hot sauce or ketchup for an extra kick.
