Step‑by‑Step Instructions for Sweet Potato Egg Casserole
Step 1: Preheat the oven
Begin by preheating your oven to 350°F (175°C) to prepare it for baking the Sweet Potato Egg Casserole. This step is essential to ensure even cooking throughout the casserole once it’s ready to be placed inside. While the oven heats up, gather your ingredients and cooking equipment, including a large skillet and a greased 9×13-inch casserole dish.
Step 2: Prepare the vegetables
Chop your sweet potatoes into 1-inch cubes, ensuring they are uniform for even cooking, and dice the onion and green pepper. Mince the garlic, setting it aside for later use. This preparation is key to allowing all the flavors to blend nicely in your casserole.
Step 3: Sauté the veggies
In a large skillet, heat a splash of avocado oil over medium heat. Add the chopped sweet potatoes, onion, and green pepper, sautéing for about 8-9 minutes until they’re softened and the onions are translucent. Stir occasionally to prevent sticking, and add the minced garlic in the last 1-2 minutes for extra flavor, ensuring it doesn’t burn.
Step 4: Combine in the casserole dish
Once the vegetables are sautéed, carefully transfer them into the greased 9×13-inch casserole dish, spreading them evenly across the bottom. This forms the flavorful base of your Sweet Potato Egg Casserole, allowing the sausage and egg mixture to adhere beautifully to the vegetables.
Step 5: Cook the turkey sausage
In the same skillet, add your turkey sausage and cook over medium-high heat, breaking it into small pieces with a spatula. Brown the sausage for about 6-8 minutes, stirring often until it’s fully cooked and golden. This adds a savory depth to the casserole while complementing the sweetness of the potatoes.
Step 6: Mix sausage and veggies
Once browned, carefully stir the cooked turkey sausage into the sautéed vegetables in your casserole dish. Make sure the sausage is evenly distributed, which will ensure that each bite of your Sweet Potato Egg Casserole is packed with flavor and protein.
Step 7: Prepare the egg mixture
In a medium bowl, whisk together the eggs, milk, fresh thyme, salt, pepper, and cheese (if using) until smooth and well combined. This creamy mixture will bind all the ingredients together, providing a rich texture to your casserole.
Step 8: Assemble and bake
Pour the prepared egg mixture over the sausage and vegetable layer in the casserole dish. Gently stir with a spatula to combine, ensuring the egg coats the ingredients evenly. Place the dish in the preheated oven and bake for 40-45 minutes, or until the center is set and the top is golden-brown.
Step 9: Rest before serving
Once baked, remove the Sweet Potato Egg Casserole from the oven and let it cool for 5-10 minutes. This resting period allows the casserole to firm up, making it easier to slice and serve. Enjoy the comforting aroma as you prepare to dig in!
