Ingredients You’ll Need

Core Ingredients and Their Roles

You’ll need 3 minced garlic cloves, 1 lb uncooked turkey sausage, 5 cups cubed sweet potatoes, 1 diced green bell pepper, and ½ large yellow onion. Add 2 tbsp avocado oil, 10 large eggs, ½ cup whole milk, ½ cup grated mozzarella cheese, 1 tsp salt, 1 tsp dried thyme, and ½ tsp pepper. Each element brings something: the sausage for flavor, the veggies for freshness, and the eggs for structure.

Best Sweet Potato Varieties for Baking

Go for orange-fleshed sweet potatoes. They bake into a tender, creamy texture without drying out. Avoid the pale, starchy ones they can turn grainy and lose their sweetness after baking.

How to Make Sweet Potato Egg Casserole Step-by-Step

Prep and Sauté the Vegetables

Preheat your oven to 350°F and grease a 9×13-inch dish. Sauté diced onion, bell pepper, and sweet potatoes in oil for about 8–9 minutes. Stir often, and add the garlic near the end. You’ll smell when it’s ready it should be fragrant and slightly caramelized.

Cook the Turkey Sausage

Use the same pan to cook the turkey sausage until browned. Break it apart into small, bite-size pieces, then mix it into the baking dish with the vegetables.

Whisk the Egg Mixture

Whisk together the eggs, milk, cheese, salt, thyme, and pepper until smooth. Pour this over the sausage and vegetables, then stir gently to combine.

Assemble, Bake, and Rest for Perfect Texture

Bake uncovered for 40–45 minutes. Check that the center feels set and no longer jiggly. If it browns too fast, cover it loosely with foil. Once baked, let it rest 10–15 minutes before slicing. This helps it set beautifully.

Tips for the Best Casserole Every Time

How to Avoid Excess Moisture

Drain the sausage and sautéed vegetables before mixing. Too much liquid can make the bottom soggy.

Getting the Sweet Potatoes to Cook Evenly

Cut them into 1-inch cubes. Smaller cubes can overcook before the eggs set. Spread them evenly in the pan so they roast, not steam.

Preventing a Rubbery or Overcooked Egg Texture

Avoid over-mixing the eggs and remove the casserole once the center is just set. Overbaking can make the eggs dry and chewy.

Easy Ingredient Substitutions and Variations

Protein Swaps

You can use chicken, pork, or plant-based sausage. Each will bring its own flavor twist, and they all work beautifully in this recipe.

Vegetable and Herb Options

Swap the bell pepper for mild chilies or spinach. Use Italian seasoning, rosemary, or sage if you like bolder herbs.

Dairy-Free or Lower-Carb Adjustments

Skip the cheese or use a dairy-free one. For fewer carbs, try mixing in cauliflower or zucchini for part of the sweet potato portion.

What to Serve with Sweet Potato Egg Casserole

Fresh and Light Breakfast Sides

Pair it with fruit salad, yogurt, or a few slices of avocado. These add freshness and brightness.

Notes

Cut sweet potatoes into uniform 1/2–1 inch cubes to ensure even cooking.

Avoid overcrowding when sautéing to prevent steaming; cook in batches if needed.

Do not over-mix eggs; this helps prevent a rubbery texture.

Let the casserole rest after baking for 5–10 minutes for best texture.

Cover with foil during baking if the top browns too fast.
