How To Make This Breakfast Casserole
Step-by-Step Instructions
- Preheat the oven to 400°F (200°C) and prepare a 9×13-inch casserole pan. Toss the diced sweet potato with olive oil, garlic powder, paprika, cumin, salt, and pepper on a baking sheet.
- Place the bacon on a separate baking sheet and bake both the sweet potato and bacon for 15 to 20 minutes, removing the bacon when crispy. Continue roasting the sweet potato for an additional 15 minutes.
- While the sweet potato cooks, brown the breakfast sausage in a pan over medium-high heat. Once cooked, transfer it to the casserole pan.
- Drain excess grease from the pan, then sauté the onion and bell pepper for 4 to 5 minutes. Add the minced garlic and sauté for another minute before transferring to the casserole pan.
- Combine the sweet potato, bacon, sausage, onion, and bell pepper in the casserole pan. Adjust seasoning with salt and pepper. If desired, add cheese at this stage.
- In a mixing bowl, whisk together the eggs and milk until frothy. Pour the egg mixture over the meat and vegetable mixture.
- Bake for 25 to 30 minutes until the center is set and the edges are golden. Slice into squares and garnish with green onion or herbs if desired.
Tips for Perfecting the Bake
For a perfectly baked casserole, make sure to whisk the eggs until frothy. This will create a light and airy texture. Also, check for doneness by inserting a knife into the center—if it comes out clean, you’re all set!
Make-Ahead & Storage Options
Preparing in Advance
If you’re short on time, prepare the meat and vegetable mixture in advance. Cover it and refrigerate overnight. The next morning, let it come to room temperature, add the eggs, and bake.
Leftover Storage and Reheating Tips
Store leftovers in an airtight container in the fridge for 4 to 5 days. To reheat, simply microwave for 30 seconds to a minute. For freezing, slice the casserole and place parchment paper between layers in an airtight container, freezing for up to 3 months. Thaw overnight in the fridge before reheating.
Serving Ideas
Garnishes and Pairings
Garnish your breakfast casserole with sliced green onions or fresh herbs for a pop of color. Serve alongside a fresh fruit salad or warm toast for a complete breakfast experience.
Creative Serving Suggestions
Consider pairing the casserole with a creamy avocado spread or a dollop of sour cream for added richness. A side of crispy hash browns can also complement the flavors beautifully.
