Nutritious Sweet Potato Egg Casserole

The morning I brought Sweet Potato Egg Casserole to our local farmers’ market brunch, the tables were already lined with baskets of herbs and jars of honey. Children chased bubbles through the sunlight while the scent of fresh bread filled the air.

In my kitchen hours earlier, I’d been peeling sweet potatoes as coffee brewed strong and rich beside me. When the casserole came out of the oven golden, steaming, fragrant with thyme and sausage it promised a good day ahead.

At the market, Chef Lena from the next stall caught the aroma and laughed, “That smells like a perfect Sunday.” I smiled, unsure how it would be received, but soon the first slices disappeared faster than I could plate them. Even the coffee roaster traded a bag of beans for a square, nodding in approval as he ate. For a simple casserole, it carried a surprising kind of warmth that gathered people together.

Since that morning, Sweet Potato Egg Casserole has quickly turned into a weekend favorite and a reliable choice for easy meal prep throughout the week. It’s wholesome, colorful, and made to share the sort of breakfast that feels honest and nourishing, like a quiet celebration of good food and good company.

Short Description

Sweet Potato Egg Casserole packed with roasted vegetables, savory turkey sausage, and creamy eggs baked to golden perfection perfect for meal prep, brunch gatherings, or cozy mornings with family.

Key Ingredients

• 2 tablespoons avocado oil
• ½ large yellow onion, chopped
• 1 green bell pepper, chopped
• 5 cups cubed sweet potatoes
• 3 garlic cloves, minced
• 1 pound turkey sausage
• 10 eggs
• ½ cup milk (plant-based milk works too)
• 1 teaspoon dried thyme
• 1 teaspoon salt
• ½ teaspoon pepper
• ½ cup grated mozzarella cheese

Tools Needed

• 9×13-inch casserole dish
• Large skillet or Dutch oven
• Whisk
• Mixing bowl
• Measuring cups and spoons
• Cutting board and knife
• Spatula

Cooking Instructions

Step 1: Prep the Vegetables
Preheat the oven to 350°F (175°C) and lightly grease your 9×13-inch casserole dish with avocado oil or butter. Chop the onion, bell pepper, and sweet potatoes into small, even cubes for uniform cooking.

Step 2: Sauté the Base
Heat avocado oil in a skillet or Dutch oven over medium heat. Add the onion, bell pepper, and sweet potatoes. Cook for 8–9 minutes, stirring occasionally until they soften and start to caramelize. In the last minute, add the minced garlic and stir until fragrant. Transfer everything to the prepared casserole dish.

Step 3: Brown the Sausage
In the same skillet, add the turkey sausage. Cook over medium heat, breaking it up into small crumbles. Once browned and fully cooked, drain any excess grease. Spread the sausage evenly over the vegetables in the casserole dish.

Step 4: Whisk the Egg Mixture
In a medium mixing bowl, whisk together eggs, milk, thyme, salt, pepper, and mozzarella until the mixture is smooth and uniform. This step ensures every bite has balanced flavor and texture.

Step 5: Combine and Bake
Pour the egg mixture evenly over the sausage and vegetables, using a spatula to gently distribute everything. Bake uncovered for 40–45 minutes, or until the center is firm and the top turns golden brown.

Step 6: Cool and Serve
Allow the casserole to cool for 15 minutes before slicing. This resting time helps it hold its shape beautifully. Serve warm with a sprinkle of fresh herbs or a drizzle of hot sauce if you like a kick.

Troubleshooting tip: If the top browns too quickly before the center sets, cover it loosely with foil for the final 10 minutes.

Large chunks may stay undercooked while others turn mushy.
Solution: Cut all cubes to roughly 1 inch and sauté before baking to ensure tenderness.

Too greasy casserole
Skipping the draining step after browning the sausage can make the dish heavy.
Solution: Drain sausage thoroughly or pat with paper towels before layering.

Soggy bottom layer
Excess moisture from vegetables can settle at the base.

4. Can I use egg whites instead of whole eggs?

5. How do I know when it’s done baking?
The top should be golden, and a knife inserted in the center should come out clean.

Tips & Tricks

Roast the sweet potatoes a day ahead to save time in the morning.

For extra flavor, add smoked paprika or crushed red pepper flakes.

Sprinkle extra cheese halfway through baking for a gooey finish.

Use a glass dish if you prefer a slightly softer texture.

Letting it rest after baking makes slicing neat and easy.

Recipe Variations

1. Mediterranean Twist: Replace sausage with crumbled feta and chopped spinach. Add sun-dried tomatoes and oregano to the egg mix. Bake as directed for a lighter, herbaceous profile.

2. Spicy Southwest Version: Swap green bell pepper for jalapeños, add black beans and corn, and top with pepper jack cheese. Serve with salsa or guacamole for a bold kick.

3. Vegetarian Delight: Skip the sausage altogether and double the veggies—mushrooms, kale, and roasted red peppers give it a rich, earthy flavor.

4. Breakfast-for-Dinner Option: Mix in chopped cooked bacon and cheddar instead of mozzarella, and serve with roasted cherry tomatoes on the side.
