Step‑by‑Step Instructions for Sweet Potato Egg Casserole
Step 1: Preheat the Oven
Begin your cooking journey by preheating your oven to 350°F (175°C). This warm embrace will ensure your Sweet Potato Egg Casserole bakes evenly and reaches that delightful golden hue. As the oven warms up, gather and prepare your ingredients, setting the stage for a delicious breakfast ahead.
Step 2: Chop the Vegetables
Next, grab your sharp knife and cutting board to chop 2 medium sweet potatoes, along with one onion and one green pepper, into 1-inch cubes. Aim for uniformity to allow even cooking. You’ll see vibrant colors forming—this is the perfect sign that your casserole base will be both nutritious and beautiful!
Step 3: Sauté the Veggies
In a large skillet over medium heat, add a splash of avocado oil, then toss in your chopped vegetables. Sauté them for about 8-9 minutes, stirring occasionally until they begin to soften and smell heavenly. In the final minute of cooking, add 2 minced garlic cloves for that aromatic kick, stirring until fragrant.
Step 4: Prepare the Casserole Dish
Spray or brush a 9×13-inch casserole dish with cooking spray or olive oil to prevent sticking. Once your vegetables are sautéed to perfection, spread them evenly across the bottom of the dish. This colorful mix will serve as the delicious foundation for your Sweet Potato Egg Casserole.
Step 5: Cook the Sausage
Using the same skillet (for added flavor), cook 1 pound of turkey sausage over medium heat until it’s nicely browned. Break the sausage into smaller pieces as it cooks, which should take about 5-7 minutes. This savory addition will elevate your casserole’s taste, making it heartier and more satisfying.
Step 6: Combine
Once the turkey sausage is cooked, drain any excess fat as necessary. Then, mix the sausage into the casserole dish with the sautéed vegetables. Stir them together gently, creating a colorful medley of flavors and textures that will be the heart of your breakfast.
Step 7: Whisk the Egg Mixture
In a separate bowl, whisk together 6 large eggs, 1 cup of milk, 1 tablespoon of fresh thyme, salt, and pepper to taste. For an extra layer of flavor, add 1 cup of shredded cheese to the mixture. Ensure it’s all combined smoothly, which will create the creamy consistency that binds your Sweet Potato Egg Casserole.
Step 8: Assemble the Casserole
Pour the prepared egg mixture evenly over the sausage and vegetable blend in the casserole dish. Gently stir with a spatula to distribute the egg mixture throughout, ensuring that every bite will be equally delicious once baked. This step is crucial for achieving an even texture in your casserole.
Step 9: Bake
Place the dish in your preheated oven and bake for 40-45 minutes. You’ll know it’s done when the center is set and the top turns a lovely golden brown, giving it an inviting appearance. If you notice it browning too quickly, feel free to cover it with foil midway through baking.
Step 10: Cool and Serve
After baking, remove the casserole from the oven and let it cool for about 15 minutes before slicing. This resting period allows the flavors to settle and makes it easier to serve. You’ll be rewarded with a deliciously fluffy Sweet Potato Egg Casserole, perfect for sharing with loved ones!

Expert Tips for Sweet Potato Egg Casserole
-
Even Dicing: Ensure your sweet potatoes and vegetables are evenly diced. This guarantees uniform cooking and a tender bite in your Sweet Potato Egg Casserole.
-
Mind the Pan: Avoid overcrowding when sautéing; cook in batches if necessary. This prevents steaming and helps achieve that lovely, golden browning on your veggies.
-
Drain Liquids: After cooking sausage and vegetables, drain any excess liquid to avoid a soggy casserole. A good balance of moisture is key to achieving the desired texture.
-
Mix Gently: When combining the egg mixture, stir gently. Over-mixing can lead to a rubbery texture, diminishing that fluffy feel you want in your casserole.
-
Rest Before Serving: Allow your baked casserole to cool for about 15 minutes before slicing. This helps it set and makes serving much easier!
Make Ahead Options
These Easy Sweet Potato Egg Casserole are perfect for busy home cooks looking to streamline their mornings! You can prepare the casserole up to 24 hours in advance by assembling it fully, then cover and refrigerate overnight. To maintain the casserole’s delightful texture, avoid adding the cheese until just before baking. When you’re ready to serve, simply preheat your oven and bake it directly from the fridge for an extra 5-10 minutes (just ensure the center is fully set). This preparation saves time and allows the flavors to meld beautifully, ensuring your Sweet Potato Egg Casserole is just as delicious!
