How to Make Healthy Breakfast Casserole
- Preheat the oven to 375°F and lightly coat a 9×13-inch baking dish with nonstick spray. This ensures your casserole cooks evenly and comes out without sticking.
- Cook the Italian sausage in a nonstick skillet over medium-high heat until browned. This step infuses your casserole with delicious savory flavors; remove the sausage and set it aside for later.
- Sauté the red bell pepper and three-fourths of the green onions in the same skillet with a splash of olive oil until tender, about 8 minutes. This will add sweetness and vibrant color to your casserole.
- Stir in the baby spinach until wilted, which should take around 2 minutes. Add this mixture to the large bowl with the sausage, combining both for a hearty filling.
- Mix in the thawed hash browns and half of the cheese gently. This creates a solid base that binds all the wonderful flavors together.
- Whisk together the eggs, milk, hot sauce, salt, and pepper in a separate bowl. Pour this creamy mixture over the hash brown-vegetable blend, ensuring everything is coated well.
- Transfer the combined mixture to the prepared baking dish, spreading it evenly. Top with the remaining cheese, adding an extra layer of melty goodness.
- Cover with foil and bake for 30 minutes. Then, remove the foil and bake again until the eggs are set and the potatoes are tender, about 15-20 additional minutes.
- Rest the casserole for a few minutes before slicing. Garnish with the remaining green onions, then slice and serve. It’s time to enjoy a delightful breakfast!
Optional: Add a side of fresh fruit salad for a refreshing touch.

Healthy Breakfast Casserole Recipe FAQs
What type of sausage is best for this casserole?
Absolutely! I recommend using high-quality Italian sausage for its bold flavor, but turkey sausage is a lighter option if you prefer. For a vegetarian version, feel free to omit the meat entirely or substitute with crumbled tempeh or tofu.
How long can I store leftovers?
Your Healthy Breakfast Casserole will stay fresh in the fridge for up to 3 days when stored in an airtight container. This is perfect for quick breakfasts during busy mornings or for enjoying as a tasty snack!

Yes, indeed! To freeze, tightly wrap the cooled casserole in plastic wrap or aluminum foil, and it will keep well for up to 3 months. When you’re ready to enjoy it again, just thaw it overnight in the fridge and bake as usual for a comforting meal.
What should I do if the casserole is too soggy?
If you find your casserole is too soggy, ensure that the hash browns and vegetables are fully thawed and sufficiently drained before mixing in. You might also want to bake it a little longer, allowing excess moisture to evaporate. Cover it with foil initially to help it cook evenly without burning on top.
Can pets eat this casserole?
While some of the ingredients (like spinach and eggs) are safe for pets, it’s best to avoid letting them have this casserole due to the salt, cheese, and spices. If treating your furry friend, a small piece of cooked egg without any seasoning is a safer option!
