Step‑by‑Step Instructions for Sweet Potato Egg Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is perfect for achieving a golden, well-cooked Sweet Potato Egg Casserole. While the oven warms up, you can prepare the other ingredients, ensuring a smoother cooking process.
Step 2: Chop the Vegetables
Next, take your sweet potatoes, onion, green pepper, and garlic, and chop them into uniform pieces. Cut the sweet potatoes into 1-inch cubes for even baking. The onion and green pepper should be diced small, while the garlic can be minced. This preparation will ensure all the flavors meld beautifully during cooking.
Step 3: Grease the Casserole Dish
Once your vegetables are chopped, grab a 9×13-inch casserole dish and grease it with some olive oil or cooking spray. This step prevents sticking and makes serving the Sweet Potato Egg Casserole easier. Set it aside, as you’ll be layering in your delicious ingredients shortly.
Step 4: Sauté the Veggies
Heat a Dutch oven over medium heat and add avocado oil. Once hot, toss in the chopped onions and green peppers, followed by the diced sweet potatoes. Sauté for about 8-9 minutes until the vegetables are softened and the onions are translucent; add the minced garlic during the last minute for optimal flavor infusion.
Step 5: Layer the Vegetables
After sautéing, remove the vegetable mixture from the heat and transfer it into your greased casserole dish. Spread them out evenly to ensure that every bite of your Sweet Potato Egg Casserole is loaded with those delicious flavors. Take a moment to admire the colorful blend before moving to the next step.
Step 6: Cook the Turkey Sausage
In the same Dutch oven, add the turkey sausage and cook over medium heat, breaking it into small pieces with your spatula. Let it brown for about 5-7 minutes until fully cooked through. This will allow the savory goodness of the sausage to intertwine with the remaining ingredients, enhancing the overall taste.
Step 7: Combine Ingredients
Remove the browned turkey sausage from the heat and add it to the casserole dish, mixing it with the sautéed vegetables. Stir gently to evenly distribute the sausage throughout the mixture, creating a hearty filling for your Sweet Potato Egg Casserole that everyone will love.
Step 8: Prepare the Egg Mixture
In a separate bowl, crack in your eggs and whisk them together with the milk, thyme, salt, pepper, and cheese until well combined. This creamy mixture will bind all the layers together beautifully. Pour this egg blend over the sausage and vegetable mixture in your casserole dish, ensuring everything is coated evenly.
Step 9: Bake the Casserole
Place the assembled casserole in your preheated oven and bake for 40-45 minutes. You’ll know it’s done when the center is firm and the top is a lovely golden brown. Keep an eye on it to ensure a perfect bake for your Sweet Potato Egg Casserole.
Step 10: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 15 minutes. This cooling period not only makes it easier to slice but also allows the flavors to settle. Now it’s ready to be served – enjoy your warm, nourishing Sweet Potato Egg Casserole!
