How to Make Easy Sweet Potato Egg Casserole Recipe

Step 1: Prepare the Vegetables

Start by heating 2 tablespoons of avocado oil in a large skillet over medium heat. Add the chopped yellow onion and green bell pepper, sautéing until they become tender and fragrant—this usually takes around 5 minutes. Then add minced garlic and cook for an additional minute to bring out its sweet aroma.

Step 2: Cook the Sweet Potatoes

Once your aromatic base is ready, add the cubed sweet potatoes to the skillet. Stir well to coat them with the flavorful mixture, cooking until they begin to soften, about 8 to 10 minutes. This step ensures the sweet potatoes are tender enough to blend perfectly into the casserole.

Step 3: Brown the Turkey Sausage

Push the sweet potatoes and vegetables to the side of the skillet, then add the turkey sausage, breaking it apart with a spatula. Cook until browned and cooked through, about 6 to 8 minutes. When everything is done, combine the sausage with the vegetables and sweet potatoes evenly in the skillet.

Step 4: Mix the Egg Base

In a large bowl, whisk together 10 eggs, ½ cup of milk, dried thyme, salt, and pepper until well combined. This mixture will give the casserole its rich, fluffy texture and bind all ingredients together beautifully.

Step 5: Assemble and Bake

Transfer the sausage and vegetable mixture into a greased baking dish. Pour the egg mixture evenly over the top, then sprinkle the grated mozzarella cheese generously. Bake in a preheated oven at 350°F (175°C) for 30 to 35 minutes, or until the eggs are fully set and the cheese is golden and bubbly.
