Simple Cooking Directions

1. Cook sausage until browned.
2. Whisk eggs, milk, and seasonings.
3. Layer bread, sausage, veggies, and cheese in a baking dish.
4. Pour egg mixture over top.
5. Bake until golden and set.
6. Cool slightly and serve warm.

Step-by-Step Recipe Preparation Method

Step 1: Cook the Sausage

1. In a large skillet, cook sausage over medium heat until browned and cooked through.
2. Drain excess fat and set aside.

Step 2: Prepare the Baking Dish

1. Lightly grease a 9×13-inch (23×33 cm) casserole dish with butter or cooking spray.

Step 3: Layer the Ingredients

1. Spread cubed bread (or hash browns) evenly in the prepared dish.
2. Sprinkle cooked sausage over the bread.
3. Add chopped onions, bell peppers, or any desired veggies.
4. Sprinkle shredded cheese evenly on top.

Step 4: Make the Egg Mixture

1. In a large bowl, whisk together eggs, milk, salt, pepper, garlic powder, onion powder, and herbs.
2. Pour evenly over the layered ingredients.
3. Press down lightly with a spoon to ensure the bread absorbs the egg mixture.

Step 5: (Optional) Refrigerate Overnight

• Cover the dish with plastic wrap and refrigerate overnight for deeper flavor and easy morning baking.

Step 6: Bake

1. Preheat oven to 350°F (175°C).
2. Bake uncovered for 45–50 minutes, or until the center is set and the top is golden brown.
3. If the top browns too quickly, cover loosely with foil during the last 10 minutes.

Step 7: Rest and Serve

• Let the casserole rest for 10 minutes before slicing.
• Sprinkle with herbs or green onions if desired.

How to Serve

Serve warm with:

• Fresh fruit or fruit salad
• Toast or English muffins
• Hot coffee or fresh orange juice

For a brunch spread, serve alongside bacon, pancakes, or a leafy green salad for balance.

Additional Recipe Tips

• Use day-old bread — it soaks up the egg mixture without becoming soggy.
• Don’t overbake — check the center; it should be firm but not dry.
• Add a dash of hot sauce or red pepper flakes for a kick.
• For extra creaminess, substitute ½ cup milk with heavy cream.
• You can assemble and refrigerate the night before, then bake fresh in the morning.

Recipe Variations

• Bacon & Cheese Casserole: Replace sausage with crispy bacon.
• Vegetarian Version: Skip sausage; add spinach, mushrooms, or roasted veggies.
• Hash Brown Casserole: Use hash browns instead of bread for a potato base.
• Southwestern Style: Add green chilies, salsa, and pepper jack cheese.
• Caprese Twist: Add cherry tomatoes, basil, and mozzarella.

Freezing and Storage

Storage:

• Store leftovers covered in the refrigerator for up to 4 days.
• Reheat in the oven at 325°F (160°C) for 10–15 minutes or microwave individual slices for 1–2 minutes.

Freezing:

• Wrap tightly in foil or plastic wrap and freeze for up to 2 months.
• Thaw overnight in the refrigerator before reheating.
