How to make it
This breakfast casserole comes together easily and offers a fragrant, satisfying meal.
- Preheat your oven to 350 degrees.

- In a medium bowl, crack the eggs and whisk well. If desired, add a few drops of hot sauce and mix until combined.

Best ways to enjoy it
Plate your sausage and egg casserole warm, and consider adding fresh salsa or avocado slices on top for a burst of flavor. It also works beautifully with a side of fresh fruit, offering a refreshing contrast to the savory casserole. The leftovers can also form the base of a nutritious breakfast burrito when wrapped in a lettuce leaf!
Storage & reheating tips
Store any leftovers in an airtight container in the fridge for up to 4 days. Reheating is simple; just microwave individual portions or reheat in the oven until warmed through. If you choose to freeze it, slice the casserole beforehand, and layer pieces with parchment paper between them to prevent sticking.
Refrigerate leftovers within 2 hours; reheat until steaming hot.
How to fix common issues
- Dry casserole: Ensure you’re not overbaking. If you find the casserole tends to dry out, add an extra egg or a splash of non-dairy milk before baking.
- Bland flavor: Don’t be shy with the seasoning! Taste your mixture before it goes into the oven.
- Soggy bottom: Ensure the veggies are well-drained, especially if using frozen spinach.
Creative twists
Feel free to modify this casserole to suit your taste. Want to switch things up? Consider adding:
- Chopped mushrooms: For an earthy flavor and additional texture.
- Zucchini or squash: Provides moisture and balances out the sausage.
- Herbs: Fresh or dried herbs can enhance the flavor significantly.
