Step‑by‑Step Instructions for Easy Sweet Potato Egg Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures your Easy Sweet Potato Egg Casserole cooks evenly and thoroughly. While the oven heats, you can focus on prepping the other ingredients, allowing everything to come together seamlessly.
Step 2: Grease the Casserole Dish
Next, take a 9×13-inch casserole dish and grease it with a light coating of cooking spray or a drizzle of avocado oil. This step helps prevent sticking and makes cleanup a breeze later on. Set the greased dish aside, ready for the delicious filling.
Step 3: Sauté the Vegetables
In a large saucepan, heat about 2 tablespoons of avocado oil over medium heat. Add 1 chopped onion, 1 chopped green pepper, and 2 cups of diced sweet potatoes. Sauté these ingredients for about 8-9 minutes, stirring occasionally, until the sweet potatoes are tender and slightly golden. During the last minute, add 2 minced garlic cloves for an aromatic finish and stir well.
Step 4: Layer the Vegetables in the Dish
Once the vegetables are sautéed, carefully transfer them into your prepared casserole dish, spreading them evenly across the bottom. This layer of sautéed goodness serves as the flavorful base of your Easy Sweet Potato Egg Casserole, providing both texture and taste for the dish.
Step 5: Cook the Turkey Sausage
In the same saucepan, add 1 pound of turkey sausage, breaking it up into smaller pieces as it cooks over medium heat. Stir frequently until fully cooked and browned, about 5-7 minutes. After cooking, drain any excess grease and combine the sausage with the sautéed vegetables in the casserole dish.
Step 6: Prepare the Egg Mixture
In a large mixing bowl, whisk together 6 eggs, 1 cup of milk, 1 tablespoon of fresh thyme (or 1 teaspoon dried thyme), and a dash of salt and pepper until the mixture is smooth and well-combined. This will add creaminess to your Easy Sweet Potato Egg Casserole and bring all the flavors together beautifully.
Step 7: Combine Everything
Carefully pour the egg mixture over the sausage and vegetable layers in the casserole dish. Using a spatula, gently stir to combine all ingredients without breaking up the sweet potatoes too much. This ensures even distribution of the egg mixture throughout the casserole, leading to a delicious final bake.
Step 8: Bake the Casserole
Place the casserole in the preheated oven and bake for 40-45 minutes. The casserole is ready when the center is firm and set. Keep an eye on it; if the top begins to brown too quickly, cover it loosely with aluminum foil to prevent burning while allowing the inside to cook through.
Step 9: Cool and Serve
Once baked, remove the Easy Sweet Potato Egg Casserole from the oven and let it cool for about 5-10 minutes before slicing. This resting time allows the flavors to meld and makes serving much easier. Serve warm, and enjoy a comforting and nutritious breakfast!

Expert Tips for Easy Sweet Potato Egg Casserole
-
Cut Consistently: Ensure your sweet potatoes are cut into uniform 1-inch cubes. This helps them cook evenly, preventing some from being undercooked while others are too soft.
-
Don’t Overcrowd the Pan: When sautéing the vegetables, avoid overcrowding the pan as it can lead to steaming instead of browning. Sauté in batches if necessary.
-
Control the Moisture: Drain any excess liquid from the cooked sausage and vegetables. This helps prevent a watery casserole and ensures a fluffy texture in your Easy Sweet Potato Egg Casserole.
-
Let It Rest: Allow the casserole to rest for 5-10 minutes after baking. This resting period solidifies the structure, making it easier to slice and serve.
-
Experiment with Ingredients: Feel free to swap out turkey sausage for vegetarian options or add other veggies like spinach. This adaptability makes the recipe versatile and fun!
Make Ahead Options
Preparing the Easy Sweet Potato Egg Casserole ahead of time is a fantastic way to save precious minutes on busy mornings! You can chop the sweet potatoes and sauté the vegetables up to 24 hours before, storing them in the refrigerator to keep them fresh. Additionally, you can cook the turkey sausage in advance and combine it with the sautéed veggies. When you’re ready to bake, simply whisk the eggs and milk, layer everything in the dish, and bake. For optimal quality, refrigerate the assembled casserole overnight and bake it fresh in the morning or reheat individual portions for a quick meal. Enjoy a warm, hearty breakfast with minimal effort!
