Ingredients:
1 pound (450 g) breakfast sausage (mild or spicy)
6–8 slices of bread (white, whole wheat, or a mix), cubed
1 1/2 cups shredded cheddar cheese (or a mix of cheddar and Monterey Jack)
8 large eggs
2 cups milk
1 teaspoon Dijon mustard (optional, for extra flavor)
1/2 teaspoon salt
1/2 teaspoon black pepper
1/4 teaspoon garlic powder (optional)
1/4 teaspoon onion powder (optional)
Optional: chopped green onions or fresh herbs for garnish
Instructions:
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C).
Grease a 9×13-inch baking dish or lightly spray with cooking spray.
Step 2: Cook the Sausage
In a large skillet, cook the sausage over medium heat until fully browned.
Break it apart into small pieces as it cooks.
Drain excess grease and set aside.
Step 3: Assemble the Casserole
Spread the cubed bread evenly in the prepared baking dish.
Sprinkle half of the shredded cheese over the bread cubes.
Evenly distribute the cooked sausage on top. Sprinkle the remaining cheese over the sausage.
Step 4: Mix the Egg Mixture
In a medium bowl, whisk together eggs, milk, Dijon mustard (if using), salt, pepper, garlic powder, and onion powder.
Pour the egg mixture evenly over the bread, cheese, and sausage in the baking dish.
Press down lightly to ensure the bread absorbs the liquid.
Step 5: Bake
Bake uncovered for 45–50 minutes, or until the eggs are set and the top is golden brown.
Let the casserole cool for 5–10 minutes before slicing.
Step 6: Serve
Garnish with chopped green onions or fresh herbs if desired. Serve warm with fresh fruit, coffee, or a side of breakfast potatoes.
Tips for the Perfect Breakfast Casserole
Make-Ahead Option: Assemble the casserole the night before, cover tightly with foil, and refrigerate. Bake in the morning, adding 10–15 extra minutes to the baking time if starting cold.
Bread Choice: Slightly stale bread works best as it absorbs the egg mixture without becoming mushy.
Cheese Variations: Use your favorite cheeses or a mix for extra flavor. Pepper jack adds a nice kick, while mozzarella gives extra gooeyness.
Add Veggies: For a healthier version, add diced bell peppers, mushrooms, or spinach to the layers.
Egg Mixture: Beating the eggs well ensures a light and fluffy texture in the baked casserole.
