Ingredients You’ll Need

The magic of this dish lies in its simple yet essential ingredients, each bringing something special—sweetness, earthiness, creaminess, or a touch of spice. These basics come together effortlessly to create layers of flavor and pleasing textures that will make your kitchen smell incredible.

Avocado oil: A healthy fat that helps sauté vegetables without overpowering their natural flavors.
Yellow onion: Adds a sweet and aromatic base that softens beautifully during cooking.
Green bell pepper: Brings a subtle bitterness and a nice pop of fresh color.
Sweet potatoes: The star ingredient offering natural sweetness and a creamy texture once cooked.
Garlic cloves: Infuse the dish with a mild pungency that enhances every bite.
Turkey sausage: A lean protein that adds savory depth without too much fat.
Eggs: Bind everything together with a fluffy, custard-like consistency.
Milk: Lightens the eggs and adds moisture; plant-based milk works well for dairy-free needs.

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), setting the stage for a perfectly baked casserole. While waiting, chop your vegetables to uniform pieces—it helps them cook evenly. Don’t forget to grease your 9×13-inch casserole dish; this simple step ensures the casserole releases easily after baking, keeping your presentation clean and inviting.

Step 2: Cook the Vegetables

Heat avocado oil in a Dutch oven or large pan until shimmering. Add your chopped onion, green bell pepper, and sweet potatoes, allowing them to sauté gently. Stir every few minutes until the vegetables soften, about 8 to 9 minutes. In the final moments, toss in minced garlic to wake up your senses with its aroma. Once cooked, spread this veggie mixture out evenly in your greased casserole dish, laying the flavorful foundation for the casserole.

Step 3: Cook the Sausage

Using the same pan for extra flavor, cook the turkey sausage thoroughly. Break it apart with a spatula so it cooks evenly into nice bite-sized pieces. Once browned and cooked through, combine the sausage with the veggie layer in your casserole dish, mixing gently to blend the savory and sweet flavors beautifully.

Step 4: Prepare the Egg Mixture

In a clean bowl, whisk together eggs, milk, dried thyme, salt, pepper, and mozzarella cheese. This mixture should come together smoothly, with cheese evenly dispersed, promising a luscious texture and a thoughtful balance of flavors when baked.

Step 5: Combine and Bake

Pour your egg mixture over the sausage and vegetable blend in the baking dish, making sure to distribute it evenly by gently stirring. Place the dish in your preheated oven and bake for 40 to 45 minutes. The casserole is done when the center feels firm to the touch and the edges are golden. If you notice the top browning too quickly, loosely tent it with foil to keep it from burning while the inside finishes baking.

Step 6: Cool and Serve

Once baked, let your Easy Sweet Potato Egg Casserole rest for at least 15 minutes. This resting time is crucial—it allows the casserole to set, making it much easier to cut and serve, while the flavors meld into a harmonious whole. Then, slice and serve this cozy dish, instantly warming and satisfying all who dig in.

How to Serve Easy Sweet Potato Egg Casserole

Garnishes

Adding fresh garnishes like chopped parsley, a sprinkle of sliced green onions, or a dash of crushed red pepper flakes can elevate the dish visually and flavor-wise. These touches provide contrast and an added layer of freshness that complements the richness of the casserole.

Side Dishes

Pair this casserole with light, crisp sides such as a mixed green salad with a tangy vinaigrette or steamed asparagus to balance the hearty nature of the dish. Fresh fruit, like orange segments or berries, also makes a perfect refreshing accompaniment, creating a well-rounded meal.

Creative Ways to Present

Try serving your Easy Sweet Potato Egg Casserole in individual ramekins for a fun, personalized touch, or cut it into neat squares and arrange them on a wooden board for a rustic brunch spread. You can even top each piece with a dollop of sour cream or avocado for a creamy, cool contrast that’s sure to impress guests.

Make Ahead and Storage

Storing Leftovers

Leftover casserole can be stored in an airtight container in the refrigerator for up to 4 days. This makes for a convenient, ready-to-eat breakfast or snack that tastes just as delicious when cooled or gently reheated.

Freezing

If you want to enjoy this Easy Sweet Potato Egg Casserole later, freezing is a great option. Wrap portions tightly in plastic wrap and foil, or store in freezer-safe containers. The casserole will keep well in the freezer for up to 2 months without losing much flavor or texture.

Reheating

To reheat, thaw frozen portions overnight in the refrigerator if possible. Warm in the oven at 350°F (175°C) until heated through, or microwave individual servings on medium power to avoid overcooking. This ensures the casserole stays moist and flavorful, just like freshly made.

FAQs

Can I use a different type of sausage?

Is this casserole gluten-free?

Yes, all the ingredients in this recipe are naturally gluten-free, making it suitable for those with gluten sensitivities or celiac disease.

Can I make this dish vegetarian?

Instructions

Preheat Oven and Prepare the Baking Dish: Preheat your oven to 350°F (175°C). While the oven is heating, chop your vegetables. Grease a 9×13-inch casserole dish to prevent sticking during baking.
Cook the Vegetables: Heat avocado oil in a Dutch oven or large saucepan over medium heat. Add the chopped onion, green bell pepper, and cubed sweet potatoes. Cook for 8-9 minutes, stirring occasionally until vegetables begin to soften. Add minced garlic during the last 1-2 minutes. Remove cooked vegetables and evenly spread them in the prepared casserole dish.
Cook the Sausage: In the same pan, sauté the turkey sausage over medium heat. Break it into small pieces as it cooks and ensure it’s fully cooked through. Once done, add the sausage to the casserole dish with the vegetables and stir to combine.
Prepare the Egg Mixture: In a mixing bowl, whisk together the eggs, milk, dried thyme, salt, pepper, and grated mozzarella cheese until smooth and well combined.
Combine and Bake: Pour the egg mixture evenly over the sausage and vegetable mixture in the casserole dish. Stir gently to distribute the egg mixture. Bake in the preheated oven for 40-45 minutes, or until the center is firm. Cover loosely with foil if the top browns too quickly.
Cool and Serve: Remove the casserole from the oven and let it cool for about 15 minutes to allow flavors to set and make cutting easier. Serve warm and enjoy your hearty breakfast casserole.

Substitute plant-based milk for dairy milk to make the dish dairy-free.
Can be prepared a day ahead and refrigerated before baking; increase baking time by 5-10 minutes if baking from cold.

For a vegetarian version, omit sausage and add beans or tofu.
