Ingredients for Overnight Sausage and Egg Casserole

Here’s what you’ll need to prepare this flavorful casserole:

• 1 pound ground breakfast sausage
• 6 large eggs
• 2 cups whole milk
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1 teaspoon dry mustard powder
• 6 slices of white or whole-grain bread, cubed
• 1 1/2 cups shredded cheddar cheese
• 1/2 cup diced bell peppers (optional)
• 1/4 cup chopped green onions (optional)

Step-by-Step Instructions

1. Cook the Sausage

• In a large skillet, cook the ground sausage over medium heat until browned and fully cooked. Drain any excess grease and set aside to cool.

2. Prepare the Egg Mixture

• In a mixing bowl, whisk together the eggs, milk, salt, pepper, and mustard powder until well combined.

3. Assemble the Casserole

• Grease a 9×13-inch baking dish.
• Spread the cubed bread evenly across the bottom of the dish.
• Sprinkle the cooked sausage over the bread, followed by the shredded cheese and optional vegetables like bell peppers and green onions.
• Pour the egg mixture evenly over the top, ensuring all ingredients are soaked.

4. Refrigerate Overnight

• Cover the dish tightly with plastic wrap or aluminum foil and refrigerate for at least 8 hours or overnight. This allows the bread to absorb the egg mixture, creating a fluffy texture.

5. Bake the Casserole

• Preheat your oven to 350°F (175°C).
• Remove the casserole from the refrigerator and let it sit at room temperature for 15-20 minutes.
• Bake uncovered for 45-50 minutes, or until the eggs are set and the top is golden brown.

6. Serve and Enjoy

• Let the casserole rest for 5 minutes before cutting into squares. Serve warm and enjoy a delicious start to your day!

Tips for the Best Overnight Sausage and Egg Casserole

1. Use Day-Old Bread

Slightly stale bread absorbs the egg mixture better, resulting in a firmer casserole.

2. Brown the Sausage Thoroughly

Cooking the sausage until it’s golden brown enhances its flavor and prevents grease from pooling in the dish.

3. Let the Casserole Rest

Allowing the casserole to sit for a few minutes after baking helps it set and makes it easier to cut.

4. Add Fresh Herbs

For a flavor boost, sprinkle fresh parsley, chives, or thyme over the baked casserole.

Variations of Overnight Sausage and Egg Casserole

1. Vegetarian Option

Skip the sausage and load up on veggies like mushrooms, spinach, and tomatoes for a meat-free version.

2. Spicy Twist

Use spicy sausage or add diced jalapeños for a kick of heat.

3. Gluten-Free Version

Replace the bread with a gluten-free alternative or omit it entirely for a low-carb casserole.

4. Cheese Lovers’ Delight

Mix different cheeses like mozzarella, Gouda, or pepper jack for an extra cheesy flavor.

Serving Suggestions

• Classic Side Dishes: Serve with fresh fruit, crispy bacon, or a simple green salad.
• Beverage Pairings: Pair with freshly brewed coffee, orange juice, or a mimosa for a complete breakfast experience.
• Leftover Ideas: Reheat leftover casserole and serve with salsa or hot sauce for a quick and satisfying meal.
