How to Make Easy Sweet Potato Egg Casserole

Step 1: Preheat Oven and Prepare the Baking Dish

Start by preheating your oven to 350°F (175°C) for that perfect, even bake. While it’s warming up, chop all your veggies so they’re ready to go. Don’t forget to grease your 9×13-inch casserole dish generously; this keeps the casserole from sticking and ensures you get a beautiful slice every time.

Step 2: Cook the Vegetables

Heat the avocado oil in a Dutch oven or large saucepan, then toss in the chopped onion, green pepper, and sweet potatoes. Sauté for about 8 to 9 minutes, stirring occasionally, until everything is gloriously golden and just beginning to soften. In the final couple of minutes, stir in the minced garlic, letting it bloom and fill your kitchen with its mouthwatering aroma. Transfer the cooked veggies to your prepared casserole dish and spread them out evenly across the bottom.

Step 3: Cook the Sausage

In the same pan, add the turkey sausage, breaking it up into tasty little morsels as it cooks. Sauté until fully browned and cooked through. Once done, scatter the sausage over the veggies in your casserole dish and give everything a gentle mix so every scoop has a little bit of each delicious layer.

Step 4: Prepare the Egg Mixture

Grab a mixing bowl and whisk together the eggs, milk, dried thyme, salt, pepper, and shredded mozzarella cheese. Mix until fully combined and creamy, ensuring that every bit of cheese and herb will be spread throughout the casserole.

Step 5: Combine and Bake

Pour your beautifully whisked egg mixture over the veggie and sausage base in the casserole dish, gently stirring so the eggs seep throughout. Slide the dish into your preheated oven and bake for 40 to 45 minutes, until the center is set and no longer jiggles. If you notice the top browning too quickly, tent with foil. That way, you get a golden, gorgeous top without scorching.

Step 6: Cool and Serve

Once it’s cooked to perfection, pull the casserole from the oven and let it cool for about 15 minutes. This rest time allows the flavors to meld and makes slicing a breeze. Now, serve up your Easy Sweet Potato Egg Casserole warm and get ready for rave reviews!

Garnishes

Sprinkle freshly chopped chives or parsley on top for a bright, herby finish that complements the casserole’s rich flavors. A small dollop of sour cream or a few slices of ripe avocado can add luxurious creaminess, while a touch of hot sauce livens up every bite for spice lovers.

Side Dishes

This casserole pairs exceptionally well with fresh fruit salad, a crisp green salad, or toasted sourdough for a well-rounded meal. If you’re feeling extra, serve with roasted asparagus or a colorful medley of sautéed greens for an additional veggie boost.

Creative Ways to Present

Cut into squares for easy brunch buffets or slice into wedges for a more elegant sit-down meal. You can even use a round biscuit cutter to create individual servings for a fancy brunch tray.

Make Ahead and Storage

Storing Leftovers

Leftover Easy Sweet Potato Egg Casserole keeps beautifully in the fridge for up to 4 days. Let it cool fully, then cover the casserole dish with foil or transfer slices to an airtight container for convenient breakfasts all week.

Freezing

If you want to make this casserole ahead, it freezes superbly. Once cooled, wrap individual slices or the entire casserole tightly in foil, then place in a freezer bag. It will keep for up to 2 months—just be sure to label it! Thaw overnight in the fridge before reheating.

Reheating

To reheat, microwave individual portions on medium power until hot, or place the whole casserole (covered with foil) in a 325°F oven until warmed through. This keeps the eggs fluffy and the cheese melty, so every serving tastes freshly made.
