Step‑by‑Step Instructions for Easy Sweet Potato Egg Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature ensures even cooking for your Easy Sweet Potato Egg Casserole. While the oven warms, gather your ingredients and prepare your workspace for a seamless cooking experience.
Step 2: Sauté the Vegetables
In a large skillet, heat a drizzle of avocado oil over medium heat. Chop the sweet potatoes, onion, green pepper, and garlic. Add the vegetables to the skillet and sauté them for about 8-9 minutes until soft and fragrant. You’ll know they’re ready when the onions become translucent and the sweet potatoes are tender.
Step 3: Prepare the Casserole Dish
Once your vegetable mixture is cooked, remove it from heat and evenly spread it into a greased 9×13-inch casserole dish. This will create a flavorful base for your Easy Sweet Potato Egg Casserole, setting the stage for the other layered ingredients.
Step 4: Cook the Sausage
In the same skillet, add the turkey sausage, breaking it up into smaller pieces as it cooks. Continue cooking over medium heat until the sausage is fully browned, about 5-7 minutes, ensuring there are no pink spots. This step adds savory depth to your casserole.
Step 5: Combine Ingredients
Once the sausage is cooked, combine it with the sautéed vegetable mixture in the casserole dish. Gently mix everything together, ensuring an even distribution of flavors throughout the Easy Sweet Potato Egg Casserole.
Step 6: Whisk the Egg Mixture
In a separate mixing bowl, whisk together the eggs, milk, fresh thyme, salt, pepper, and shredded cheese. You want this mixture to be frothy and well-combined, which will help bind the casserole together once baked.
Step 7: Pour and Stir
Carefully pour the egg mixture over the sausage and vegetable blend in the casserole dish. Using a spatula, gently stir everything together to ensure the egg mixture coats all the ingredients evenly, bringing your Easy Sweet Potato Egg Casserole to life.
Step 8: Bake the Casserole
Place the casserole dish in the preheated oven and bake for 40-45 minutes. Keep an eye on it; the casserole is done when the center is firm and a light golden color appears on top. If it browns too quickly, cover it loosely with foil during the last few minutes.
Step 9: Cool Before Serving
Once baked, remove the Easy Sweet Potato Egg Casserole from the oven and let it cool for about 15 minutes. This resting period allows the flavors to settle, making it easier to slice and serve. Enjoy your delicious creation!
