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 step is crucial as it ensures the Sweet Potato Egg Casserole bakes evenly and at the right temperature. While the oven warms up, gather your ingredients and prepare your workspace, making cooking a smooth experience.
Step 2: Chop the Vegetables
Next, take your sweet potatoes, onion, and green pepper. Chop them into uniform 1-inch cubes to promote even cooking. This will help your casserole achieve the perfect tender texture. Set the chopped vegetables aside in a bowl as you prepare to sauté them shortly.
Step 3: Prepare the Casserole Dish
Grease a 9×13-inch casserole dish using a light spray of cooking oil or a paper towel coated with avocado oil. This prevents the Sweet Potato Egg Casserole from sticking and makes cleanup easier later. Set the greased dish aside as you cook the filling.
Step 4: Sauté the Vegetables
In a large skillet, heat a drizzle of avocado oil over medium heat. Add the chopped onions, green pepper, and sweet potatoes, sautéing for 8-9 minutes, or until they begin to soften. Stir occasionally to ensure even cooking, and add fresh minced garlic for the last minute to prevent burning.
Step 5: Layer the Vegetables
Once your vegetables are sautéed to tenderness, remove them from the heat. Carefully spread the sweet potato and vegetable mixture evenly in your greased casserole dish, creating a colorful base. This will be the foundation of your hearty Sweet Potato Egg Casserole, preparing it for the next layers.
Step 6: Cook the Sausage
In the same pan, add your turkey sausage and cook over medium heat until browned, about 5-7 minutes. Remember to break the sausage into small pieces with a spatula as it cooks, ensuring every bite is packed with flavor. Remove excess liquid before mixing it into the casserole.
Step 7: Combine Ingredients
Once the turkey sausage has browned, combine it with the sautéed vegetables in the casserole dish. Mix them gently but thoroughly; this step ensures that each serving of the Sweet Potato Egg Casserole is both flavorful and satisfying, with every element well-distributed.
Step 8: Whisk the Egg Mixture
In a mixing bowl, crack open the eggs and whisk them together with milk, thyme, salt, pepper, and shredded cheese until the mixture is smooth and well-combined. This egg mixture acts as the binding agent for your casserole, enhancing its creaminess and flavor profile.
Step 9: Pour and Stir
Pour the egg mixture evenly over the vegetable and sausage combination in the casserole dish. Using a spatula, gently stir to combine the elements, ensuring the egg mixture saturates everything beneath, ensuring each bite of the Sweet Potato Egg Casserole is moist and delicious.
Step 10: Bake the Casserole
Place the casserole in your preheated oven and bake for 40-45 minutes. Keep an eye on the casserole; it’s done when the center is firm and no longer jiggly. If you notice the top browning too quickly, feel free to cover it loosely with aluminum foil to maintain an even bake.
Step 11: Cool Before Serving
Once baked, remove the Sweet Potato Egg Casserole from the oven and let it cool for about 5-10 minutes before slicing. This resting time will allow the casserole to set properly, making it easier to cut into squares and serving portions that hold together beautifully.

How to Store and Freeze Sweet Potato Egg Casserole
- Fridge: Store leftovers in an airtight container for up to 4 days. Ensure the casserole is completely cooled before sealing to maintain freshness.
- Freezer: Wrap portions tightly in plastic wrap, then place them in a freezer bag to prevent freezer burn. This way, you can enjoy your Sweet Potato Egg Casserole for up to 3 months!
- Reheating: To reheat, simply thaw in the fridge overnight, then warm in the microwave or oven until heated through. If reheating from frozen, bake at 350°F (175°C) for about 30-35 minutes, covered with foil.
- Room Temperature: If you plan to serve right away, allow the casserole to sit at room temperature for no more than 2 hours to ensure food safety and quality.

Sweet Potato Egg Casserole Recipe FAQs
What kind of sweet potatoes should I use for the casserole?
I recommend using Garnet or Jewel sweet potatoes. They have a lovely natural sweetness and hold their shape well when cooked, ensuring a delicious texture throughout your casserole. Avoid using sweet potatoes with dark spots or extensive bruising, as they may not have the same flavor and can affect the overall dish.
How should I store leftovers of the Sweet Potato Egg Casserole?
Leftovers can be stored in an airtight container in the fridge for up to 4 days. Make sure the casserole is completely cool before sealing it, as this helps maintain its freshness and prevents moisture buildup.
Can I freeze the Sweet Potato Egg Casserole? If so, how?
Absolutely! To freeze, wrap portions of the casserole tightly in plastic wrap, ensuring there’s minimal air to avoid freezer burn. Then, place the wrapped portions in a freezer-safe bag or container. You can freeze it for up to 3 months. When ready to eat, thaw it in the fridge overnight and reheat in the microwave or bake at 350°F (175°C) for about 30-35 minutes, covered with foil to heat evenly.
What should I do if the casserole comes out too watery?
If your casserole ends up watery, it’s likely due to excess moisture from the cooked vegetables and sausage. To prevent this in the future, make sure to drain any liquid after sautéing your vegetables or cooking the sausage. Also, allowing the casserole to rest for 5-10 minutes before slicing will help it set and firm up nicely.
Is this Sweet Potato Egg Casserole suitable for dietary restrictions?
Yes! This recipe is very adaptable. You can easily make it vegetarian by omitting the turkey sausage and adding in extra vegetables like spinach or zucchini. It’s also gluten-free as written, so it works well for those avoiding gluten. Just check your cheese and milk choices to ensure they fit specific dietary needs.
