Ingredients You’ll Need

To make this Easy Sweet Potato Egg Casserole, you only need a handful of thoughtfully chosen ingredients. Each plays a crucial role—whether it’s the creamy texture that eggs bring, the warmth and sweetness from the sweet potatoes, or the savory depth from the turkey sausage. These basic yet essential items come together beautifully to create a dish that tastes special without a complicated shopping list.

Avocado oil: Provides a mild, healthy fat perfect for sautéing vegetables without overpowering flavors.
Yellow onion: Adds a subtle sweetness and depth when cooked down.
Green bell pepper: Contributes a fresh, crisp texture and vibrant color.
Sweet potatoes: The star ingredient, delivering natural sweetness and hearty body to the casserole.
Garlic cloves: Infuses a fragrant, savory punch that elevates the entire dish.
Turkey sausage: Brings protein and a savory, meaty goodness with less fat than traditional pork sausage.
Eggs: The binding and fluffy component that holds all ingredients together.
Milk (or plant-based milk): Adds creaminess to the egg mixture for a perfectly tender bake.
Dried thyme: Introduces a subtle herbal note that pairs beautifully with the sweet potatoes and sausage.
Salt and pepper: Essential seasonings that enhance all flavors.
Mozzarella cheese: Melts into creamy pockets of cheese that add a delightful cheesiness without overwhelming the dish.

How to Make Easy Sweet Potato Egg Casserole

Step 1: Preheat Oven and Prepare the Baking Dish

Start by heating your oven to 350°F (175°C). This ensures it’s at the ideal temperature for slow, even baking. While the oven warms up, chop your vegetables—this prep work makes the whole process feel smooth and efficient. Don’t forget to grease your 9×13-inch casserole dish well, so nothing sticks and cleaning up is a breeze after your delicious meal.

Step 2: Cook the Vegetables

Heat the avocado oil in a Dutch oven or large pan until shimmering. Add the onion, green pepper, and sweet potatoes and cook for about 8 to 9 minutes. Stir occasionally as the veggies soften and start to release their wonderful aromas. During the last couple of minutes, toss in the garlic to infuse that irresistible garlicky fragrance without burning it. Once everything is tender, spread the mixture evenly in your prepared baking dish as the base layer of flavor and color.

Step 3: Cook the Sausage

Using the same pan makes cleanup simpler and keeps those built-up flavor bits. Add the turkey sausage and cook it thoroughly, breaking it into small crumbles as it browns. This step ensures each bite has a perfect balance of meaty savory notes that complement the sweet potatoes beautifully. Once cooked, stir the sausage into the vegetable layer, so all your flavors begin to mingle in the casserole dish.

Step 4: Prepare the Egg Mixture

In a separate bowl, whisk together your eggs, milk, dried thyme, salt, pepper, and shredded mozzarella cheese. This smooth, velvety mixture is what brings everything together and creates that soft, delicate texture that makes the Easy Sweet Potato Egg Casserole so irresistible. Make sure it’s well combined before moving on to pouring it over your savory base.

Step 5: Combine and Bake

Pour the egg mixture over your sausage and vegetable blend in the baking dish. Give it a gentle stir so the egg distributes evenly without disturbing the layers too much. Slide the casserole into the hot oven and bake for 40 to 45 minutes until the center is set and firm. Keep an eye on it midway through—if the top gets too browned, cover loosely with foil, protecting that beautiful golden crust from burning.

Step 6: Cool and Serve

When your timer goes off and the casserole feels fully set, take it out of the oven and let it rest for about 15 minutes. This step is key because it allows the eggs to finish settling and makes slicing easier. Plus, it gives you a chance to prepare your coffee or fresh juice while anticipating the delicious first bite of your homemade breakfast masterpiece.

How to Serve Easy Sweet Potato Egg Casserole

Garnishes

Adding a sprinkle of freshly chopped herbs like parsley or chives gives your casserole an extra pop of color and freshness. A dash of hot sauce or a spoonful of Greek yogurt on top can also complement the creamy and savory profile beautifully if you like a little zing or creaminess in each bite.

Side Dishes

This Easy Sweet Potato Egg Casserole pairs wonderfully with a crisp green salad for freshness or a side of roasted tomatoes for a juicy burst. If you want to keep things cozy, some warm crusty bread or buttery biscuits make for perfect dippers to soak up any extra eggy goodness.

Creative Ways to Present

For a brunch gathering, serve this casserole in individual ramekins for attractive single servings or layer it with a colorful salad buffet so guests can customize their plates. You could also swap out the turkey sausage for bacon or even make a vegetarian version by omitting the meat and adding mushrooms or spinach for a vibrant twist.

Make Ahead and Storage

Storing Leftovers

Once cooled, cover any leftover casserole tightly with plastic wrap or store it in an airtight container. It will keep well in the fridge for up to 3 days, making it perfect for busy mornings when you want a nutritious breakfast without the fuss.

Freezing

This casserole freezes beautifully. Portion it into single servings or freeze the whole dish before baking. Wrap tightly with foil or plastic wrap and place in a freezer-safe container. Frozen casserole can last up to 2 months without losing flavor or texture.

Reheating

Reheat frozen or refrigerated portions in the oven at 325°F (160°C) until warm throughout, about 15 to 20 minutes for leftovers. For quicker reheats, microwave slices covered loosely with a damp paper towel to keep moisture in. Either way, your Easy Sweet Potato Egg Casserole will taste just as comforting as when freshly baked.

FAQs

Can I use regular potatoes instead of sweet potatoes?

Absolutely! While sweet potatoes provide a lovely natural sweetness and tender texture, regular russet or Yukon gold potatoes can be a great alternative if you prefer a more neutral flavor.

Is turkey sausage necessary, or can I use something else?

You can swap turkey sausage with pork sausage, chicken sausage, or even plant-based sausage for a vegetarian-friendly or different flavor profile. The key is to use a sausage that you enjoy and that cooks well into small pieces.

Can this casserole be made vegetarian?

Yes! Simply omit the sausage and consider adding sautéed mushrooms, spinach, or other veggies to boost the savory flavor and texture in your Easy Sweet Potato Egg Casserole.

What type of cheese works best in this recipe?

Mozzarella melts beautifully and keeps the casserole creamy without overpowering the other ingredients. However, mild cheddar, Monterey Jack, or a blend of cheeses can be fantastic alternatives.

Can I prepare this casserole the night before?

Yes, you can assemble it the night before and store it covered in the fridge. When ready to eat, just pop it in the preheated oven and bake until set and golden. This makes it perfect for an effortless morning meal!
