- 1/2 cup finely chopped red bell pepper
- 2 cups cubed bread (stale or fresh, any kind works well)

How to Make Sausage Breakfast Mini Casserole
This Sausage Breakfast Mini Casserole is designed for ultimate ease and maximum deliciousness. In under an hour, you’ll have perfectly portioned, savory delights ready to go. The combination of savory sausage, tender vegetables, fluffy eggs, and melted cheese creates a deeply satisfying texture and flavor profile.
Step-by-Step Instructions
- Preheat Oven and Prepare Muffin Tin: Preheat your oven to 375°F (190°C). Lightly grease a 12-cup muffin tin with cooking spray or butter, or line each cup with paper liners for easier cleanup.
- Cook the Sausage: In a large skillet over medium heat, crumble and cook the breakfast sausage until fully browned and cooked through. If your sausage is particularly greasy, you can drain off excess fat, leaving a tablespoon or two in the pan for flavor.
- Sauté the Vegetables: Add the chopped yellow onion, green bell pepper, and red bell pepper to the skillet with the cooked sausage. Cook, stirring occasionally, until the vegetables have softened, about 5-7 minutes.
- Combine Ingredients for the Casserole Base: In a large mixing bowl, combine the cooked sausage and vegetable mixture. Add the cubed bread to the bowl.
- Whisk the Egg Mixture: In a separate medium bowl, whisk together the 6 large eggs, 1 1/2 cups milk, salt, pepper, and cayenne pepper (if using) until well combined and slightly frothy.
- Assemble the Mini Casseroles: Pour the egg and milk mixture evenly over the sausage, vegetable, and bread mixture in the large bowl. Gently stir to ensure all the bread cubes are moistened and the ingredients are well distributed. Be careful not to overmix.
- Fill the Muffin Cups: Spoon the mixture evenly into the prepared muffin cups, filling each about two-thirds to three-quarters full. You should have enough mixture for all 12 cups.
- Top with Cheese: Sprinkle the shredded cheddar cheese evenly over the top of each mini casserole.
- Bake: Place the muffin tin on a baking sheet (to catch any potential drips) and bake in the preheated oven for 20-25 minutes, or until the casseroles are set in the center and golden brown on top. A toothpick inserted into the center should come out clean.
- Cool Slightly: Let the mini casseroles cool in the muffin tin for a few minutes before carefully removing them. This makes them easier to handle and less likely to fall apart.

Storing and Reheating Tips
For optimal freshness, once the Sausage Breakfast Mini Casseroles have cooled completely, store them in an airtight container in the refrigerator. They will stay fresh and delicious for up to 3-4 days.
To reheat, you have a few simple options:
- Oven Reheating: For the closest to freshly baked taste and texture, place individual or a few mini casseroles on a baking sheet and reheat in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until warmed through. Loose tenting with foil can prevent the tops from getting too brown.
- Microwave Reheating: For a quick heat-up, place one or two mini casseroles on a microwave-safe plate and microwave on medium power for 45-90 seconds, or until heated through. Test for warmth before consuming.
Freezing for Future Meals:
To freeze these Sausage Breakfast Mini Casseroles, ensure they are completely cooled. Wrap each individual mini casserole tightly in plastic wrap, then enclose them in a freezer-safe bag or container. They can be stored in the freezer for up to 2-3 months. Thaw overnight in the refrigerator before reheating using the oven or microwave methods described above.
