Ingredients You’ll Need

This Easy Sweet Potato Egg Casserole calls for simple, wholesome ingredients that are easy to find but essential for creating layers of flavor. Each one plays a key role in building the texture, taste, or savory sweetness you’ll love.

• 2 tablespoons avocado oil: Adds a subtle, healthy fat perfect for sautéing vegetables without overpowering the dish.

• 1 pound turkey sausage: Adds savory, protein-packed goodness without too much heaviness.
• 10 eggs: The binding agent that creates a fluffy, custardy base holding the casserole together.
• 1/2 cup milk (plant-based milk can be substituted): Softens the egg mixture for that creamy consistency.
• 1 teaspoon dried thyme: Offers a subtle herbaceous note, complementing the sweetness of the potatoes.
• 1 teaspoon salt: Enhances all the natural flavors in the casserole perfectly.
• 1/2 teaspoon pepper: Adds a gentle kick to keep things interesting.
• 1/2 cup grated mozzarella cheese: Melts beautifully on top, adding a gooey, cheesy finish.

How to Make Easy Sweet Potato Egg Casserole

Step 1: Prepare the Vegetables and Sausage

Begin by heating your avocado oil over medium heat in a large skillet. Toss in the chopped onion and green bell pepper, sautéing them until they soften and start to caramelize, about 5 minutes. Then add the garlic and cook for another minute until fragrant. Next, crumble in the turkey sausage, breaking it up as it browns evenly, mixing it with the veggies for a savory base.

Step 2: Cook the Sweet Potatoes

While the sausage and vegetables are cooking, add the cubed sweet potatoes to the skillet. Stir everything together, covering the skillet for about 10 minutes to allow the sweet potatoes to soften while keeping some firmness—you want them tender but not mushy. Stir occasionally to prevent sticking and ensure even cooking.

Step 3: Mix the Egg Custard

In a large bowl, whisk together the eggs, milk, dried thyme, salt, and pepper until well combined and smooth. This mixture will set the foundation of your casserole, giving it that fluffy, custardy texture we all crave.

Step 4: Assemble the Casserole

Preheat your oven to 375°F (190°C). Lightly grease a baking dish, then spread the sausage and vegetable mixture evenly across the bottom. Pour the egg mixture over the top, making sure it seeps into every corner. Sprinkle the grated mozzarella cheese evenly across the surface for that irresistible golden finish.

Step 5: Bake to Perfection

Place the casserole in the oven and bake for 35–40 minutes or until the eggs are fully set and the cheese on top is melted and slightly browned. A toothpick inserted in the center should come out clean. Let it rest for about 5 minutes before slicing—a little patience goes a long way to achieve the perfect texture.

How to Serve Easy Sweet Potato Egg Casserole

Garnishes

Fresh herbs like chopped parsley or chives sprinkled on top add a burst of color and brightness. A dollop of tangy Greek yogurt or avocado slices can also give a wonderful creaminess that contrasts nicely with the savory casserole.

Side Dishes

Pairing this casserole with a crisp green salad or some roasted asparagus balances the meal beautifully. For those who enjoy a touch of sweetness, consider serving with fresh fruit salad or a fruit compote to complement the sweet potatoes.

Creative Ways to Present

For a brunch spread, cut the casserole into individual squares and serve on colorful plates alongside small bowls of salsa or hot sauce. You can also turn leftovers into hearty breakfast burritos by wrapping pieces of the casserole in warm tortillas with fresh greens and a drizzle of hot sauce.

Make Ahead and Storage

Storing Leftovers

Any leftover Easy Sweet Potato Egg Casserole can be stored in an airtight container in the refrigerator for up to 4 days. It tastes just as good cold or reheated, making it a convenient option for busy breakfasts or dinners throughout the week.

Freezing

You can freeze portions of the casserole by wrapping them tightly in plastic wrap and aluminum foil or placing them in freezer-safe containers. Make sure to consume frozen leftovers within 2 months for the best texture and flavor preservation.

Reheating

Reheat your casserole slices in the microwave for a minute or two, or warm them up in the oven at 350°F (175°C) for about 10–15 minutes until heated through. The oven method helps maintain the crispy edges and melty cheese topping perfectly.

FAQs

Can I use a different type of sausage?

Absolutely! Feel free to substitute turkey sausage with pork, chicken, or even a plant-based sausage depending on your preferences. Just be sure to adjust the seasoning slightly if the sausage is particularly spicy or seasoned.

Is it possible to make this casserole dairy-free?

Yes, simply use a plant-based milk substitute like almond or oat milk in place of regular milk, and swap the mozzarella for a dairy-free cheese alternative. The casserole will still be creamy and delicious.

Can I prepare this casserole the night before?

Definitely. You can assemble the casserole the night before, cover it tightly, and refrigerate. Then bake it fresh in the morning. This makes it a fantastic option for stress-free entertaining or a busy weekday breakfast.

What can I add to make this casserole more veggie-packed?

Additions like chopped spinach, kale, or mushrooms work well stirred into the sausage and vegetable mixture before baking. They add nutrients and bulk without altering the comforting flavor too much.

How do I know when the casserole is fully cooked?

The edges will be golden and slightly crispy while the eggs should be set firm but tender. If you’re unsure, insert a toothpick or knife into the center; it should come out clean without wet egg mixture.
