Equipment

You only need a few basic kitchen tools for this Overnight Breakfast Casserole with Sausage & Cheese.

• Skillet: To brown the sausage before assembly.

Instructions

Creating your Overnight Breakfast Casserole with Sausage & Cheese is incredibly simple. Follow these steps for a perfect breakfast.

1. Brown and Drain Sausage: Cook the ground breakfast sausage in a skillet over medium heat until it is fully browned. Drain off any excess grease thoroughly. Ensuring proper cooking temperatures for ground meats like sausage is crucial for food safety, with specific USDA guidelines for safe sausage cooking.
2. Prepare Baking Dish: Lightly grease a 9×13 inch baking dish to prevent sticking.
3. Layer Bread: Spread the cubed bread evenly across the bottom of the prepared baking dish.
4. Add Sausage and Cheese: Sprinkle the browned sausage evenly over the bread cubes. Then, layer the shredded cheddar cheese over the sausage.
5. Whisk Egg Mixture: In a large measuring cup or bowl, whisk together the eggs, milk, dry mustard, salt, and pepper until well combined.
6. Pour Over Layers: Carefully pour the egg mixture evenly over the bread, sausage, and cheese in the baking dish. Ensure all ingredients are moistened.
7. Cover and Chill: Cover the baking dish tightly with plastic wrap or foil. Refrigerate it overnight, allowing the flavors to meld.
8. Preheat Oven: The next morning, preheat your oven to 325°F (160°C). Remove the casserole from the refrigerator while the oven preheats.
9. Bake Casserole: Bake the casserole for 45-55 minutes. For the first 30 minutes, cover the dish loosely with foil to prevent over-browning. Then, remove the foil and bake uncovered for the remaining time.
10. Check for Doneness: The casserole is done when the eggs are set and a knife inserted into the center comes out clean. Baking time varies, depending on your oven and desired egg firmness.
11. Serve Warm: Remove the Overnight Breakfast Casserole with Sausage & Cheese from the oven. Let it stand for a few minutes before slicing and serving warm.

Pro Tips & Troubleshooting

Achieve the perfect Overnight Breakfast Casserole with Sausage & Cheese every time with these expert tips.

Perfecting Your Casserole

• Prevent a Soggy Bottom: Use slightly stale or toasted bread. This helps the bread absorb the egg mixture without becoming mushy.
• Adjust Baking Time: Bake until the internal temperature reaches 160°F (71°C) for fully set eggs. To guarantee food safety, particularly when cooking dishes containing eggs, reaching the correct safe internal temperature for egg dishes is essential. Adjust for your preferred texture.
• Even Cheese Melt: Sprinkle some cheese on top during the last 10-15 minutes of baking for a perfectly melted, golden crust.
• Prevent Over-Browning: Cover the casserole loosely with aluminum foil for the first two-thirds of the baking time.

Troubleshooting

• Eggs Not Set: If the center is still jiggly, cover with foil and return to the oven for 10-15 minute increments.
• Avoiding a Dry Casserole: Do not overbake. Remove the casserole once a knife inserted comes out clean, but before it feels rubbery.

Serving, Storage & Variations

Elevate your Overnight Breakfast Casserole with Sausage & Cheese with thoughtful serving ideas and smart storage.

Serving Suggestions

• Serve alongside warm coffee or orange juice.
• Offer sweet contrasts like cinnamon rolls, French toast, or muffins.
• Provide hot sauce or ketchup for those who enjoy an extra kick.

Storage & Reheating

• Refrigerator: Store leftovers in an airtight container in the refrigerator for up to 3-4 days.
• Reheating Whole Casserole: Reheat in a 300°F (150°C) oven, covered with foil, until warmed through.
• Reheating Individual Servings: Microwave individual portions for 1-2 minutes until hot.

Flavor Variations

• Different Cheeses: Try Monterey Jack, Swiss, or a sharp provolone to change the profile.
