Step‑by‑Step Instructions for Easy Sweet Potato Egg Casserole
Step 1: Preheat the Oven
Begin your delicious journey by preheating your oven to 350°F (175°C). This temperature is perfect for cooking the casserole evenly, ensuring that the sweet potatoes and egg mixture come together beautifully. While the oven heats, you can prepare your casserole dish for an effortless baking experience.
Step 2: Prepare the Casserole Dish
Grease a 9×13-inch casserole dish generously with your favorite cooking oil or non-stick spray. This step is crucial for preventing the Easy Sweet Potato Egg Casserole from sticking, allowing for easy serving later. Set aside this prepared dish while you move on to the flavorful filling.
Step 3: Sauté the Vegetables
In a Dutch oven, heat a tablespoon of avocado oil over medium heat. Add chopped onion, green pepper, and sweet potato cubes, stirring occasionally for about 8-9 minutes until they soften. The sweet potatoes should be tender but not falling apart. In the last minute, stir in minced garlic, allowing its aromatic flavor to bloom before removing the pot from heat.
Step 4: Layer the Vegetables in the Dish
Spread the sautéed vegetable mixture evenly in the prepared casserole dish, creating a vibrant and colorful base for your Easy Sweet Potato Egg Casserole. The combination of sweet, savory, and aromatic ingredients will form a delightful foundation. This is a moment to appreciate the fragrant blend you've created.
Step 5: Cook the Turkey Sausage
Return to your Dutch oven and add the turkey sausage, breaking it into small pieces as it cooks over medium heat. Stir until the sausage is fully cooked and no longer pink, which usually takes about 5-7 minutes. Once done, mix this savory sausage into the vegetable layer in the casserole dish, ensuring even distribution.
Step 6: Prepare the Egg Mixture
In a mixing bowl, whisk together eggs, milk, fresh thyme, salt, pepper, and shredded cheese until the mixture is smooth and well-combined. This creamy egg base is key to holding the layers together in your Easy Sweet Potato Egg Casserole. Make sure to incorporate the cheese thoroughly for maximum flavor.
Step 7: Combine and Pour
Pour the egg mixture over the sausage and vegetable layer in the casserole dish. Gently stir with a spatula to distribute the egg mixture evenly, ensuring every bite of your casserole will be packed with flavor. The colors and textures should blend beautifully, promising a hearty breakfast.
Step 8: Bake the Casserole
Place the filled casserole dish into your preheated oven. Bake for 40-45 minutes, or until the center is firm and a light golden color appears on top. If the surface browns too quickly, cover it loosely with aluminum foil to prevent overcooking. This time is crucial for achieving that perfect fluffy texture in your Easy Sweet Potato Egg Casserole.
Step 9: Rest Before Serving
Once baked, remove the casserole from the oven and let it cool for 15 minutes before slicing. This cooling period helps the casserole set, making it easier to serve and maintain its shape. The enticing aroma will fill your kitchen, making the wait all the more worthwhile!
