- Nutritious and satisfying: Sweet potatoes provide fiber and vitamins, while eggs and sausage add protein.

Ingredients Overview
Sweet Potatoes Choose orange-fleshed sweet potatoes for their sweet flavor and creamy texture. Cut them into even cubes so they roast uniformly and stay tender inside the casserole.
Turkey Sausage Turkey sausage adds savory depth without being too heavy. You can use chicken sausage, or even plant-based sausage if preferred.
Bell Peppers and Onions These vegetables add sweetness, color, and flavor. Any color of bell pepper works, but red and yellow add a bright contrast.
Eggs and Milk Eggs create the custard base that binds the casserole together. A splash of milk keeps the texture light and fluffy. You may also use almond, oat, or soy milk for a dairy-free version.
Cheese Mozzarella is a great option for its mild flavor and melting quality, but cheddar, Monterey Jack, or a dairy-free cheese alternative all work well.
How to Make Easy Sweet Potato Egg Casserole
1. Prepare the Sweet Potatoes
Peel the sweet potatoes and cut them into small cubes. Toss them with oil, salt, pepper, and your preferred seasoning (such as thyme, rosemary, or paprika). Roast them until tender and lightly golden.
2. Cook the Sausage
Brown the turkey sausage in a skillet. Break it into small pieces to ensure even distribution throughout the casserole. Remove from the pan once cooked.
3. Sauté the Vegetables
Using the same skillet, cook the onions and bell peppers until soft. This step deepens the flavor and prevents sogginess in the final dish.
4. Mix the Egg Base
Whisk together the eggs, milk, salt, pepper, and herbs. Avoid overmixing because it can make the eggs rubbery during baking.
5. Assemble
Layer the roasted sweet potatoes, sausage, cooked vegetables, and shredded cheese in a casserole dish. Pour the egg mixture evenly over everything.
6. Bake
Bake until the casserole is fully set and the top is lightly golden. Allow it to rest for a few minutes before slicing; this helps maintain clean, firm pieces.
Substitutions and Variations
This casserole is incredibly flexible. Here are some great variations:
- Vegetarian option: Skip the sausage or replace it with plant-based crumbles.
- Spicy version: Add jalapeños, crushed red pepper flakes, or spicy sausage.
- More veggies: Spinach, mushrooms, kale, or zucchini work well.
- Different cheeses: Cheddar for sharpness, Gruyère for richness, or pepper jack for a spicy twist.
- Herb variations: Try sage, oregano, basil, or Italian seasoning.
Tips for Success
- Cut evenly: Uniform sweet potato cubes help everything cook at the same time.
- Don’t overcrowd the skillet: Browning vegetables and sausage adds important flavor.
- Let it rest: Allow the casserole to sit for 5–10 minutes after baking for the perfect texture.
- Avoid soggy casserole: Drain excess liquid from vegetables and do not add too much milk.
Serving Suggestions
This dish is satisfying on its own but pairs beautifully with:
- A fresh fruit salad
- Toasted sourdough or whole grain bread
- Sliced avocado or guacamole
- A simple green salad with lemon dressing
It also works as a healthy lunch option, especially when served with a protein like grilled chicken or beans.
Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days.
- Freezer: Freeze individual portions for up to 3 months.
- Reheat: Microwave slices for 1–2 minutes, or warm the entire dish in the oven at 350°F until heated through.
Conclusion
The Easy Sweet Potato Egg Casserole is everything you want in a breakfast recipe: simple, nutritious, customizable, and delicious. Whether you’re feeding a family, preparing weekday meals, or hosting a brunch, this casserole delivers flavor and convenience every single time.
