Ingredients You’ll Need

These ingredients are wonderfully straightforward yet each one shines, contributing vibrant flavors, hearty texture, and a beautiful color palette to your Easy Sweet Potato Egg Casserole. From the sweetness of the potatoes to the richness of the eggs and cheese, every component plays a vital role.

• 2 tablespoons avocado oil: A healthy fat perfect for sautéing vegetables without overpowering their natural flavors.
• 1/2 large yellow onion, chopped: Adds a subtle sweetness and depth as it softens during cooking.
• 1 green bell pepper, chopped: Brings a mild crunch and vibrant color that pairs beautifully with the sweet potatoes.
• 5 cups cubed sweet potatoes: The star ingredient, offering natural sweetness and hearty texture to the casserole.
• 3 garlic cloves: Infuses a warm, aromatic punch that complements the sausage and vegetables.
• 1 pound turkey sausage: A lean protein source that adds savory flavor without excess grease.
• 10 eggs: The binding agent that holds the casserole together with a tender, fluffy consistency.
• 1/2 cup milk (plant-based can be substituted): Adds creaminess to the egg mixture for a velvety texture.
• 1 teaspoon dried thyme: An herbaceous touch that brightens the casserole’s flavor profile.
• 1 teaspoon salt: Enhances all the natural flavors in the dish.
• 1/2 teaspoon pepper: Adds just the right amount of gentle heat and complexity.
• 1/2 cup grated mozzarella cheese: Melts beautifully on top, creating a golden and gooey finish.

How to Make Easy Sweet Potato Egg Casserole

Step 1: Preheat Oven and Prepare the Baking Dish

Start by setting your oven to 350°F (175°C). This ensures it’s hot and ready for baking once all your ingredients are prepped. While the oven warms up, chop the onion, green bell pepper, and sweet potatoes into nice, bite-sized cubes. Don’t forget to grease a 9×13-inch casserole dish — this step is key to making sure nothing sticks and cleanup is a breeze later on.

Step 2: Cook the Vegetables

Heat the avocado oil in a large pan or Dutch oven over medium-high heat. Toss in the chopped onion, green pepper, and sweet potatoes. Let these cook for about 8-9 minutes, stirring occasionally, until the sweet potatoes start to soften and the onions become translucent. Towards the end, stir in the minced garlic and sauté for another minute to release its irresistible aroma. Once done, spread the cooked veggies evenly on the bottom of your greased casserole dish.

Step 3: Cook the Sausage

Using the same pan, add your turkey sausage. Break it up gently with your spoon or spatula as it cooks to brown all over evenly. It usually takes about 5-7 minutes until it’s cooked through with no pink remaining. Drain any excess fat if necessary, then scatter the sausage evenly over the layer of vegetables in your casserole dish.

Step 4: Mix and Pour the Egg Batter

In a large mixing bowl, whisk together the eggs, milk, dried thyme, salt, and pepper. The milk helps make the eggs fluffy and tender while the thyme gives a lovely herby note. Pour this mixture over the sausage and vegetables, making sure it spreads out evenly. Finally, sprinkle the grated mozzarella cheese across the top for that signature melty finish.

Step 5: Bake to Perfection

Place your casserole in the preheated oven and bake for 35-40 minutes. You’ll know it’s ready when the eggs are fully set and the cheese is golden and bubbly. A toothpick inserted in the center should come out clean. This baking time gives everything a chance to meld together into a comforting, savory bake that’s as satisfying as it is pretty.

How to Serve Easy Sweet Potato Egg Casserole

Garnishes

Fresh herbs like chopped parsley or chives sprinkled on top add a bright, fresh pop of color and flavor that contrasts happily with the rich baked egg and sausage. For a little extra kick, a dash of hot sauce or a dollop of sour cream makes a fantastic accompaniment.

Side Dishes

Pair this casserole with a crisp green salad or some roasted asparagus for a balanced meal. It also works beautifully alongside fresh fruit or a slice of crusty whole-grain bread to round out your brunch spread.

Creative Ways to Present

Serve portions in individual ramekins for a charming, personal touch at brunch parties or simply cut into squares and pile onto a vibrant platter garnished with herbs and bright veggies. You can also layer in some sautéed mushrooms or swap mozzarella for a sharp cheddar to change the flavor profile up whenever you like.

Make Ahead and Storage

Storing Leftovers

Once cooled, cover your Easy Sweet Potato Egg Casserole tightly with foil or plastic wrap and store in the fridge for up to 4 days. It reheats beautifully and tastes just as delicious the next day.

Freezing

This casserole freezes well if you want to prepare in advance. Wrap it tightly with plastic wrap and then foil or place in a freezer-safe container. Freeze for up to 3 months. To thaw, move it to the fridge overnight before reheating.

Reheating

Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through. Microwaving works too if you’re short on time, but reheating in the oven keeps the edges delightfully crisp.
