Sausage, Cheese, and Egg Casserole: A Breakfast Classic

The scent of sausage sizzling in the pan always takes me back to weekend mornings at my grandmother’s house. Waking up to that aroma meant a hearty, comforting breakfast was on its way, and her sausage, cheese, and egg casserole was the star of the show. It was always the perfect balance of savory and cheesy, a true family favorite that fueled countless memories. Now, I’m excited to share that same warmth and deliciousness with you.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 1 hour 30 minutes
• Total Time: 1 hour 50 minutes (plus overnight refrigeration)
• Servings: 6
• Yield: 1 casserole
• Dietary Type: Not Gluten-Free

Ingredients

• 12 cups seasoned croutons
• 2 cups sharp cheddar cheese, grated
• 1 1/2 lbs bulk sausage
• 4 eggs
• 2 1/2 cups milk
• 3/4 teaspoon dry mustard
• 1/2 teaspoon salt
• 1 dash pepper
• 1 can cream of mushroom soup
• 1/2 cup milk

Equipment Needed

• Greased Casserole Dish
• Large Skillet
• Mixing Bowl
• Whisk

Instructions

1. Start by evenly spreading the seasoned croutons on the bottom of your greased casserole dish. This forms the base of the casserole and soaks up all the delicious flavors.
2. Sprinkle 1 1/2 cups of the grated sharp cheddar cheese on top of the croutons. This layer of cheese will melt beautifully during baking, binding the croutons and sausage together.
3. In a large skillet over medium heat, brown the bulk sausage. Make sure to break it up into crumbles as it cooks. Once the sausage is fully cooked, drain off any excess grease. Nobody wants a greasy casserole!
4. Spread the cooked and drained sausage evenly over the layer of cheese in the casserole dish. This hearty sausage layer is the protein powerhouse of our casserole.
5. In a mixing bowl, crack the eggs and add the milk, dry mustard, salt, and pepper. Whisk everything together until well combined. The dry mustard adds a subtle tang that complements the other flavors perfectly.
6. Pour the egg mixture evenly over the sausage layer in the casserole dish. Ensure that all the croutons and sausage are submerged in the egg mixture.
7. Cover the casserole dish with plastic wrap and refrigerate overnight. This allows the croutons to fully absorb the egg mixture and the flavors to meld together. Don’t skip this step!
8. The next day, preheat your oven to 300°F (150°C). This lower temperature allows the casserole to cook evenly without drying out.
9. In a separate bowl, dilute the cream of mushroom soup with 1/2 cup of milk. Stir until smooth and well combined.
10. Pour the diluted cream of mushroom soup evenly over the refrigerated casserole. This adds a creamy, savory element that elevates the dish.
11. Sprinkle the remaining 1/2 cup of sharp cheddar cheese on top of the soup layer. This final layer of cheese will create a golden-brown, bubbly topping during baking.
12. Bake in the preheated oven for 1 1/2 hours. The casserole is done when it is golden brown and set in the center. A toothpick inserted into the center should come out clean.
13. Let the casserole stand for a few minutes before serving. This allows it to set up a bit more and makes it easier to slice.

Expert Tips & Tricks

• For a richer flavor, use a blend of cheeses instead of just cheddar. Try adding some Monterey Jack or Gruyere.
• If you’re short on time, you can skip the overnight refrigeration, but the casserole will be even better if you allow the flavors to meld.
• To prevent the top from browning too quickly, you can tent the casserole with foil during the last 30 minutes of baking.
• Feel free to customize the sausage. Spicy Italian sausage will add a kick, while breakfast sausage keeps it classic.
• If you find the croutons are getting too dark during baking, place a sheet of aluminum foil loosely over the top of the casserole for the remaining cooking time.

Serving & Storage Suggestions

This sausage, cheese, and egg casserole is best served warm, straight from the oven. Cut it into squares and serve as a hearty breakfast or brunch dish. It pairs perfectly with a side of fresh fruit, a dollop of sour cream, or a sprinkle of fresh herbs.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave individual portions or bake the entire casserole in a preheated oven at 350°F (175°C) until warmed through.

For longer storage, the casserole can be frozen. Allow it to cool completely, then wrap it tightly in plastic wrap and foil. It can be stored in the freezer for up to 2 months. To reheat, thaw it overnight in the refrigerator and then bake as directed above.
