Step‑by‑Step Instructions for Potato Egg Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it heats, prepare a 9×13-inch casserole dish by greasing it with avocado oil to prevent sticking. This will ensure your savory Potato Egg Casserole comes out easily once baked. Having everything ready sets you up for a smooth cooking experience!
Step 2: Sauté the Vegetables
Chop the sweet potatoes into 1-inch cubes, and heat 2 tablespoons of avocado oil in a large skillet over medium heat. Add the sweet potatoes, onion, green pepper, and minced garlic, sautéing for about 9 minutes until the vegetables soften slightly. Stir frequently until everything glistens and becomes aromatic, creating a flavorful base for your casserole.
Step 3: Spread the Vegetables
Once the vegetables are slightly softened, carefully spread them evenly across the greased casserole dish. This layer will serve as the foundation for your mouthwatering Potato Egg Casserole. Make sure the mixture is distributed evenly to ensure that all portions bake uniformly, enhancing the overall flavor profile.
Step 4: Cook the Turkey Sausage
In the same skillet, add the turkey sausage over medium heat, using a spatula to break it into small pieces as it browns. Cook for about 5-7 minutes, or until fully cooked and no longer pink. Once done, drain any excess grease and add the sausage on top of the sautéed vegetables in the casserole dish.
Step 5: Whisk the Egg Mixture
In a medium-sized mixing bowl, whisk together the eggs, milk, fresh thyme, salt, and pepper until smooth. This is the heart of your Potato Egg Casserole, so take a moment to ensure the mixture is well combined and frothy, which will yield a light and fluffy texture when baked.
Step 6: Combine the Ingredients
Pour the egg mixture over the sautéed vegetables and sausage in the casserole dish. Use a spatula to stir gently, ensuring that the ingredients are evenly coated with the egg mixture. This will help bind the casserole together, making it cohesive and full of flavor throughout.
Step 7: Bake the Casserole
Carefully place the casserole in the preheated oven and bake for 40-45 minutes. Keep an eye on it; the center should be firm and set, and you may cover it with foil if the top browns too quickly. The delightful aroma of the Potato Egg Casserole will fill your kitchen, making your mouth water!
Step 8: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool for about 15 minutes before slicing. This resting time helps the casserole set, allowing for cleaner slices. After cooling, you’re ready to serve this hearty and nutritious Potato Egg Casserole, perfect for breakfast gatherings or meal prep!

Make Ahead Options
These Sweet Potato Egg Casserole preparations are great for anyone looking to simplify their mornings! You can chop and sauté the sweet potatoes, onions, green peppers, and garlic up to 24 hours in advance; simply store them in an airtight container in the refrigerator to preserve freshness. Additionally, you can cook the turkey sausage ahead of time and refrigerate it as well. When you’re ready to serve, just mix the prepped ingredients with the egg and milk mixture, pour it all into your casserole dish, and bake as instructed. This allows you to enjoy a delicious, homemade breakfast with minimal effort, making it ideal for busy weeknights or family brunches!
