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 ensures the Sweet Potato Egg Casserole bakes evenly and turns golden brown. While your oven heats, gather your ingredients and equipment, including a 9×13-inch casserole dish.
Step 2: Chop the Vegetables
Carefully chop the sweet potatoes into ½-inch cubes, and dice the onion and green pepper. Aim for uniform sizes to ensure even cooking. Set aside your chopped vegetables, ready for sautéing, while enjoying the vibrant colors that will come together in your casserole.
Step 3: Prepare the Casserole Dish
Grease your 9×13-inch casserole dish with a little butter or cooking spray. A well-greased dish will help prevent the Sweet Potato Egg Casserole from sticking, ensuring easy serving later on. With that done, you’re ready for the next step!
Step 4: Sauté the Vegetables
In a large saucepan, heat a splash of avocado oil over medium heat. Add chopped onions, green pepper, and sweet potatoes, sautéing for about 8-9 minutes until softened. Stir occasionally, and in the final minute, add minced garlic to release its aroma and flavor, creating a savory base for your casserole.
Step 5: Assemble the Base
Once your vegetables have softened, spread them evenly across the bottom of the greased casserole dish. This colorful base is where all the delicious flavors of the Sweet Potato Egg Casserole will meld perfectly during baking.
Step 6: Cook the Turkey Sausage
Using the same pan, add the turkey sausage and cook until browned, breaking it into small pieces. This should take about 5–7 minutes. Once cooked, combine the sausage with the sautéed vegetables, creating a hearty filling that will add protein and flavor to your casserole.
Step 7: Whisk the Egg Mixture
In a separate bowl, whisk together the eggs, milk, fresh thyme, salt, pepper, and shredded cheese until smooth. This creamy egg mixture will bind all the ingredients together beautifully, adding richness to your Sweet Potato Egg Casserole.
Step 8: Combine Everything
Pour the egg mixture evenly over the sausage and vegetable mixture in the casserole dish. Gently stir to combine, ensuring that the vegetables and sausage are well-coated without over-mixing, which could lead to a tougher texture.
Step 9: Bake to Perfection
Place your casserole in the preheated oven and bake for 40-45 minutes. Keep an eye on it; if the top browns too quickly, cover it loosely with aluminum foil to prevent burning. The casserole is ready when it’s puffed up and lightly golden.
Step 10: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for 15 minutes. This resting period will help it set, making it easier to cut into squares for serving. Now, you can enjoy a slice of your delicious Sweet Potato Egg Casserole, perfect for breakfast or a cozy brunch!

Make Ahead Options
Preparing the Sweet Potato Egg Casserole ahead of time is a game-changer for busy mornings! You can chop the sweet potatoes and vegetables up to 24 hours in advance, storing them in an airtight container in the refrigerator to maintain their freshness. Additionally, you can cook the turkey sausage and refrigerate it for up to 3 days. When you’re ready to serve, simply assemble the casserole by layering the sautéed ingredients in the dish, whisking the egg mixture, and pouring it on top before baking. This method allows you to have a delicious, hearty breakfast ready with minimal effort, ensuring it’s just as delightful as if you made it fresh that morning!
