Ingredients:
- 2 tablespoons avocado oil
- 1/2 large yellow onion, chopped
- 1 green bell pepper, chopped
- 5 cups cubed sweet potatoes
- 3 garlic cloves, minced
- 1 pound ground turkey sausage
- 10 large eggs
- 1/2 cup milk (dairy or plant-based like almond or oat milk)
- 1 teaspoon dried thyme
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 cup grated mozzarella cheese
Prepping the Sweet Potatoes and Aromatics
Step 1: Sautéing the Vegetables
Begin by heating the 2 tablespoons of avocado oil in a large oven-safe skillet or a 9×13 inch baking dish set over medium heat. Once the oil is shimmering, add your chopped 1/2 large yellow onion and the chopped 1 green bell pepper. Sauté these vegetables for about 5-7 minutes, stirring occasionally, until they start to soften and the onion becomes translucent. This initial sautéing step builds a flavorful base for our casserole. While the onions and peppers are cooking, mince your 3 garlic cloves.
Step 2: Adding Sweet Potatoes and Garlic
Once the onions and peppers have softened, add the 5 cups of cubed sweet potatoes to the skillet. If you haven’t already, add the minced garlic to the skillet as well. Stir everything together to coat the sweet potatoes and vegetables with the oil. Continue to cook for another 8-10 minutes, stirring every few minutes, allowing the sweet potatoes to begin to soften slightly. You don’t want them fully cooked at this stage; they will finish cooking in the oven. This partial cooking helps ensure an even texture throughout the final casserole.
Cooking the Sausage and Preparing the Egg Mixture
Step 3: Browning the Turkey Sausage
Push the sweet potato mixture to one side of the skillet (or remove it to a bowl temporarily if your skillet isn’t large enough). Add the 1 pound of ground turkey sausage to the empty side of the skillet. Break up the sausage with a spoon and cook it, stirring occasionally, until it’s nicely browned and cooked through. Once the sausage is cooked, drain off any excess grease. Then, stir the browned sausage into the sweet potato and vegetable mixture. This ensures all the delicious flavors are combined.
Step 4: Whisking the Egg Base
While the sausage is cooking or after it’s been incorporated, it’s time to prepare the creamy egg mixture. In a large bowl, crack your 10 large eggs. Add the 1/2 cup of milk, 1 teaspoon of dried thyme, 1 teaspoon of salt, and 1/2 teaspoon of black pepper. Whisk vigorously until the egg yolks and whites are completely combined and the mixture is a uniform pale yellow color. Ensure the seasonings are evenly distributed. This egg mixture will bind all the delicious ingredients together and create that classic casserole texture.
Assembling and Baking the Casserole
Step 5: Combining and Baking
Pour the whisked egg mixture evenly over the sweet potato, vegetable, and sausage mixture in the skillet. Gently stir to distribute everything, making sure the sweet potatoes and sausage are mostly submerged in the egg mixture. If you used a separate bowl for the sweet potato mixture, now is the time to transfer everything back into your oven-safe skillet or a greased 9×13 inch baking dish. Sprinkle the 1/2 cup of grated mozzarella cheese evenly over the top of the casserole.
Step 6: Baking to Perfection
Preheat your oven to 375°F (190°C). Place the skillet or baking dish in the preheated oven. Bake for 35-45 minutes, or until the eggs are set and the top is golden brown and bubbly. You can test for doneness by inserting a knife into the center; it should come out clean. If the top starts to brown too quickly before the eggs are set, you can loosely tent the casserole with aluminum foil. Let the casserole rest for about 5-10 minutes before slicing and serving. This allows the casserole to firm up, making it easier to cut and serve. Enjoy your hearty and delicious Easy Sweet Potato Egg Casserole!
