How to Make Overnight Sausage and Egg Breakfast Casserole
- Brown the Sausage: In a large skillet over medium heat, cook the sausage until browned and crispy. As the sausage sizzles, the mouthwatering aroma will fill your kitchen and draw everyone in.
- Saute the Veggies: Once the sausage is cooked, add the diced onion and bell pepper. Sauté until soft, about 5-7 minutes. The combination of savory sausage and sweet onions is irresistible!
- Prepare the Casserole Dish: Grease a 9×13-inch baking dish and layer the cubed bread evenly across the bottom.
- Combine Ingredients: In a large mixing bowl, whisk together the eggs, milk, salt, and pepper. Stir in the cooked sausage mixture and half of the cheese. Pour this delightful mixture over the cubed bread.
- Add the Cheese: Sprinkle the remaining cheese on top. The more, the merrier!
- Cover and Refrigerate: Cover the casserole with plastic wrap or foil and refrigerate overnight. This soak time allows the bread to absorb the egg mixture perfectly.
- Bake: In the morning, preheat your oven to 375°F (190°C). Remove the cover and bake for 45-50 minutes, or until the center is set and the top is golden and bubbly.
- Serve and Enjoy: Once it’s out of the oven, let it rest for a few minutes, then slice and serve warm, garnished with fresh herbs if desired.
Tips and Creative Variations
- Spice it up: Add jalapeños or hot sauce for a kick.
- Herbaceous Flair: Incorporate fresh herbs like chives or parsley into the egg mixture.
- Meat-Free Option: Substitute sausage with crumbled tofu or veggie sausage for a vegetarian version.
- Holiday Touch: Incorporate cranberries or pecans during festive seasons for a unique flair.
Serving Ideas
Picture this warm casserole as the centerpiece of your breakfast table. Pair it with crispy hash browns, fresh fruit, or a vibrant avocado salad. A steaming cup of coffee or a refreshing mimosa makes this meal feel extra special—imagine laughter bubbling around the table, stories swapping back and forth, all while enjoying a slice of this delightful dish.
Storing and Reheating
This casserole is perfect for leftovers! Here’s how to store it:
- Refrigerate: Store covered in the fridge for up to 3 days.

- Reheat: Simply pop it in the microwave for a quick warm-up or place it in an oven preheated to 350°F (175°C) until heated through for that fresh-baked taste.
Pro Tips for Success
- Use Day-Old Bread: It absorbs the egg mixture better. If it’s too fresh, the bread may turn mushy.
- Customize Cheese: A mix of cheddar and mozzarella adds layers of flavor and gooeyness.
- Egg Substitutes: If you’re out of eggs, use flaxseed meal mixed with water as a binding agent—perfect for a plant-based version.
- Sauté Early: Cooking the sausage and veggies the night before can deepen flavors and save time in the morning.
