Overnight Egg Casserole With Sausage and Cheese: A Savory Morning Delight

The scent of sausage sizzling in a pan always transports me back to my grandmother’s cozy kitchen. Every Christmas morning, amidst the flurry of gift-wrapping and excited chatter, she would present her signature breakfast casserole. The aroma alone was enough to coax even the sleepiest family members out of bed. This recipe, while slightly lighter, captures that same comforting essence, blending savory sausage, crusty bread, and cheesy goodness into an unforgettable start to the day.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 55 minutes
• Total Time: 1 hour 15 minutes + Overnight Refrigeration
• Servings: 4
• Yield: 1 (8-inch) Casserole
• Dietary Type: High Protein

Ingredients

• Cooking spray
• ½ lb bulk turkey sausage
• ¼ teaspoon fennel seed
• ¼ teaspoon dried oregano leaves
• ¼ lb French bread, cut into ½-inch cubes
• 1 (8 ounce) carton egg substitute
• ⅔ cup skim milk
• ½ cup evaporated skim milk
• 1 teaspoon dry mustard
• ⅛ teaspoon cayenne pepper
• Dash black pepper
• Paprika (to garnish)
• ½ cup grated reduced-fat sharp cheddar cheese

Equipment Needed

• Nonstick skillet
• Paper towels
• 8-inch square baking pan
• Mixing bowl
• Aluminum foil

Instructions

1. Preheat a nonstick skillet coated with cooking spray over medium-high heat for about 1 minute. This ensures the pan is hot enough to properly brown the sausage.
2. Add the bulk turkey sausage, fennel seed, and dried oregano leaves to the preheated skillet.
3. Cook the sausage mixture until it is fully browned, breaking it apart with a spoon as it cooks. This step is crucial for developing the savory flavor that anchors the casserole.
4. Once the sausage is browned, transfer it to a plate lined with paper towels to drain off any excess grease. Set aside. Draining the sausage will prevent the casserole from becoming overly greasy.
5. Coat an 8-inch square baking pan with cooking spray. This will prevent the casserole from sticking to the pan.
6. Line the bottom of the prepared baking pan with the French bread cubes. Ensure they are evenly distributed. The bread will soak up the egg mixture overnight, creating a delightful texture.
7. Sprinkle the cooked and drained sausage evenly over the layer of bread cubes.
8. In a separate mixing bowl, combine the egg substitute, skim milk, evaporated skim milk, dry mustard, cayenne pepper, and black pepper. Whisk thoroughly until all ingredients are well combined. The dry mustard and cayenne pepper add a subtle kick to the flavor profile.
9. Pour the egg mixture evenly over the sausage and bread in the baking pan. Make sure all the bread cubes are moistened.
10. Cover the baking pan tightly with aluminum foil.
11. Refrigerate the casserole overnight, or for at least 8 hours. This allows the bread to fully absorb the egg mixture, resulting in a richer, more flavorful casserole.
12. Preheat the oven to 350°F (175°C).
13. Bake the covered casserole for 55 minutes. Baking it covered prevents the top from browning too quickly and ensures the casserole is cooked through.
14. Remove the foil and sprinkle the grated reduced-fat sharp cheddar cheese evenly over the top of the casserole.
15. Return the casserole to the oven (uncovered) and bake for an additional 5 minutes, or until the cheese is melted and bubbly. Watch carefully to prevent burning.
16. Remove the casserole from the oven and let it cool for 5 minutes before cutting. This allows the casserole to set slightly, making it easier to slice and serve.
17. Garnish with paprika for a pop of color.
18. Cut the casserole into quarters and serve warm.

Expert Tips & Tricks

• For an extra layer of flavor, consider adding sauteed vegetables like onions, peppers, or mushrooms to the sausage mixture.
• If you don’t have French bread on hand, you can substitute it with any other type of sturdy bread, such as sourdough or Italian bread.
• To ensure the casserole is fully cooked, insert a knife into the center. If it comes out clean, the casserole is ready.
• If the top of the casserole starts to brown too quickly, you can loosely cover it with foil during the last 15 minutes of baking.
• For a creamier casserole, use whole milk or half-and-half instead of skim milk and evaporated skim milk.
• Don’t skip the overnight refrigeration! This is crucial for allowing the bread to soak up the liquid and develop the flavors.

Serving & Storage Suggestions

This overnight egg casserole with sausage and cheese is best served warm, straight from the oven. It’s a perfect dish for breakfast, brunch, or even a light dinner. Garnish with a sprinkle of fresh parsley or a dollop of sour cream for added visual appeal.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave individual portions for 1-2 minutes, or until heated through. You can also reheat the entire casserole in the oven at 350°F (175°C) for about 20 minutes, or until warmed through.

Freezing is not recommended as the texture of the bread may change upon thawing.

FAQs (Frequently Asked Questions)

Q: Can I make this casserole the same day I want to bake it?
A: While it’s best to refrigerate the casserole overnight, you can get away with refrigerating it for at least 4 hours if you’re short on time. The longer it sits, the more the bread will absorb the egg mixture, resulting in a better texture.

Q: Can I use regular eggs instead of egg substitute?
A: Yes, you can use 6 large eggs in place of the egg substitute. Whisk them well before adding them to the other ingredients.

Q: How do I prevent the casserole from drying out?
A: Make sure to cover the casserole with foil during the first 55 minutes of baking. This will help to trap moisture and prevent the top from becoming too dry.

Q: Can I add different types of cheese?
A: Absolutely! Feel free to experiment with different cheeses like mozzarella, Gruyere, or pepper jack. Just be sure to use a cheese that melts well.

Q: What if I don’t have evaporated skim milk?
A: You can substitute it with an equal amount of regular skim milk or half-and-half. Keep in mind that using half-and-half will increase the fat content of the casserole.
