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 step is crucial for ensuring your Easy Sweet Potato Egg Casserole bakes evenly and reaches that delightful golden-brown color. While the oven is warming, you can prepare your ingredients, allowing the casserole to bake perfectly once it’s assembled.
Step 2: Prepare the Vegetables
Cube the sweet potatoes into 1/2-inch pieces and chop the onion and green pepper. Mince the garlic for added flavor. This prep will ensure that all the ingredients meld beautifully together. Set aside your prepared vegetables in a bowl, ready for the next steps.
Step 3: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of avocado oil over medium heat. Add the sweet potatoes, onion, and green pepper, sautéing for 8–9 minutes until they soften and become fragrant. In the final minute, add the minced garlic. You’re looking for the sweet potatoes to be tender but still holding their shape.
Step 4: Transfer to Casserole Dish
Once the vegetables are sautéed to perfection, transfer them into a greased 9×13-inch casserole dish. Ensuring the dish is well-greased prevents any sticking and makes for easier serving. Spread the mixture evenly across the dish to create a solid bed for your casserole.
Step 5: Cook the Turkey Sausage
In the same skillet, add the turkey sausage and cook until browned, about 5–7 minutes. As it cooks, break it into small pieces for even distribution in the casserole. Once browned, combine the sausage with the sautéed vegetables in your casserole dish to enhance flavor and protein levels.
Step 6: Whisk the Egg Mixture
In a separate bowl, whisk together the eggs, milk, thyme, salt, pepper, and shredded cheese until fully combined. This mixture is vital as it binds all the ingredients together for your Easy Sweet Potato Egg Casserole, creating a rich and creamy texture.
Step 7: Combine Ingredients
Pour the egg mixture evenly over the vegetable and sausage blend in the casserole dish. Gently stir to ensure everything is well-coated with the egg mixture. The bright colors and hearty ingredients will start to come together beautifully.
Step 8: Bake the Casserole
Place the casserole in the preheated oven and bake for 40–45 minutes. The casserole is done when the center is firm and no longer jiggly, and the top is golden brown. If you notice it browning too quickly, cover it with foil halfway through to prevent over-browning.
Step 9: Cool Before Serving
Once baked, remove the Easy Sweet Potato Egg Casserole from the oven and allow it to cool for 10–15 minutes before slicing. This resting time helps the casserole set and makes it easier to serve, ensuring you get nice, clean portions.
