Charleston Breakfast Casserole Recipe

Sausage: Adds a savory and rich flavor to the casserole. You can use any type of sausage you prefer.

Eggs: Provides structure and richness to the dish.

Milk: Helps to create a creamy texture and binds the ingredients together.

Salt: Enhances the flavors of the other ingredients.

Dry mustard: Adds a subtle tangy flavor that complements the sausage and cheese.

Bread: Acts as a base and absorbs the egg mixture, creating a fluffy texture.

Cheddar cheese: Adds a rich, cheesy flavor and helps to bind the casserole together.

When preparing the bread cubes for this casserole, consider using slightly stale or day-old bread. This will help the bread absorb the egg mixture more effectively, resulting in a firmer and more cohesive casserole. Additionally, to ensure even distribution of the sausage and cheese, layer them in the baking dish before pouring the egg mixture over the top. This technique helps prevent clumping and ensures every bite is packed with flavor.

• Allow the Charleston breakfast casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
• For short-term storage, cover the baking dish tightly with aluminum foil or plastic wrap. Alternatively, transfer the casserole to an airtight container. Store in the refrigerator for up to 3-4 days.
• To freeze, cut the cooled casserole into individual portions. Wrap each portion tightly in plastic wrap, then place the wrapped pieces in a freezer-safe zip-top bag or airtight container. Label with the date and freeze for up to 2-3 months.
• When ready to reheat, thaw the frozen portions in the refrigerator overnight. This ensures even reheating and maintains the texture of the casserole.
• Reheat individual portions in the microwave. Place on a microwave-safe plate and cover with a damp paper towel to retain moisture. Heat on medium power for 2-3 minutes, or until heated through.
• For oven reheating, preheat the oven to 350°F (175°C). Place the thawed casserole portions in an oven-safe dish, cover with aluminum foil, and bake for 15-20 minutes, or until warmed through.
• To keep the cheese topping from drying out during reheating, consider adding a small amount of milk or cream over the top before covering with foil.
• Avoid reheating the casserole more than once, as this can affect the texture and flavor.

• Preheat your oven to 350°F (175°C). Place the leftover Charleston Breakfast Casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Bake for 20-25 minutes or until heated through. This method ensures the casserole retains its original texture and flavor.

• For a quicker option, use the microwave. Place a portion of the casserole on a microwave-safe plate. Cover it with a microwave-safe lid or a damp paper towel to keep it moist. Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating. Be cautious not to overheat, as this can make the eggs rubbery.

• If you have an air fryer, preheat it to 300°F (150°C). Place the casserole in the basket, ensuring it’s not overcrowded. Heat for about 5-7 minutes, shaking the basket halfway through. This method gives a slightly crispy edge while keeping the inside moist.

• On the stovetop, use a non-stick skillet over medium-low heat. Add a small amount of butter or olive oil to the pan. Place the casserole in the skillet, cover with a lid, and heat for 5-7 minutes, flipping halfway through. This method is great for a quick reheat with a bit of added flavor from the butter or oil.

• For a steam reheat, place the casserole in a heatproof dish that fits inside a steamer basket. Bring a pot of water to a simmer and place the steamer basket over the pot. Cover and steam for about 10 minutes. This method keeps the casserole moist and prevents it from drying out.
