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 will ensure it’s hot enough to properly cook your Sweet Potato Egg Casserole once you’re ready to bake. While your oven warms up, gather all your ingredients and have a 9×13-inch casserole dish ready for later use.
Step 2: Prepare the Vegetables
Chop the sweet potatoes, onion, green pepper, and garlic into small, uniform pieces to promote even cooking. Aim for ½ inch cubes for the sweet potatoes. Set aside your chopped vegetables in a bowl, ready to sauté. The vibrant colors of these ingredients will make your casserole visually appealing!
Step 3: Sauté the Vegetables
Grease your casserole dish with a little avocado oil. In a large skillet over medium heat, add the oil and sauté the onions and garlic for about 2 minutes until fragrant. Then, add the sweet potatoes and green pepper, cooking for 8-9 minutes until they’re softened and lightly browned, creating a delicious aroma.
Step 4: Arrange the Vegetables
Once sautéed, transfer the vegetables into the greased casserole dish, spreading them evenly across the bottom. This layer will serve as the flavorful foundation for your Sweet Potato Egg Casserole. Enjoy the sight of the colorful veggies before moving on to the next step.
Step 5: Cook the Turkey Sausage
In the same skillet, add the turkey sausage over medium heat. Cook it for about 5–6 minutes until fully cooked, breaking it into small pieces as it cooks. This will add savory depth to your casserole. Drain any excess liquid, then mix the sausage with the sautéed vegetables in the casserole dish.
Step 6: Whisk the Egg Mixture
In a separate mixing bowl, whisk together the eggs, milk, thyme, salt, pepper, and shredded cheese until smooth. This mixture will bind together all your delicious ingredients in the Sweet Potato Egg Casserole. The creamy texture should be velvety and inviting, promising a satisfying breakfast.
Step 7: Combine Ingredients
Pour the egg mixture evenly over the sausage and vegetable blend in the casserole dish. Use a spatula to gently stir and combine everything, ensuring that the egg coats all the vegetables and sausage. This step is crucial for a well-rounded flavor and texture throughout your casserole.
Step 8: Bake the Casserole
Place your casserole in the preheated oven and bake for 40-45 minutes. The top should turn a lovely golden brown, and the center should be firm to the touch. If it starts browning too quickly, loosely cover it with foil. The delightful smell will fill your kitchen as it bakes!
Step 9: Rest Before Serving
Once baked, remove the Sweet Potato Egg Casserole from the oven and let it rest for about 15 minutes. This resting period allows the casserole to set perfectly and makes it easier to cut into portions. During this time, you can set the table and prepare any sides you wish to serve with it.

Make Ahead Options
These Sweet Potato Egg Casseroles are a dream for busy home cooks! You can prep the entire casserole up to 24 hours in advance by assembling it in the dish, covering it tightly with plastic wrap, and refrigerating it overnight. Alternatively, cook and store any leftover casserole in an airtight container for up to 4 days in the fridge. If you’re looking to store it longer, freeze individual portions for up to 3 months. To enjoy, simply bake it straight from the fridge (add a few extra minutes to the baking time) or thaw overnight if frozen, then pop it in the oven. This way, you’ll savor the same delightful flavors of your freshly made Sweet Potato Egg Casserole, effortlessly!
