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 temperature is perfect for baking the Sweet Potato Egg Casserole, allowing it to cook evenly and develop a golden, fluffy top. Make sure your oven reaches the desired heat before proceeding to the next step for optimal results.

Step 2: Prepare the Vegetables
In a large saucepan, heat a tablespoon of avocado oil over medium heat. Chop your sweet potatoes into 1-inch cubes along with the onion and green pepper. Sauté the vegetables in the heated pan for about 8-9 minutes, stirring occasionally, until they soften. Add minced garlic in the last 1-2 minutes of cooking to infuse the dish with flavor.

Step 3: Combine in Casserole Dish
Once your vegetables are sautéed, grease a 9×13-inch casserole dish with a touch of oil or butter. Spread the warm sautéed mixture evenly across the bottom of the dish. This layer of colorful veggies will be the flavorful base of your Sweet Potato Egg Casserole and will ensure every bite is packed with nutrition.

Step 4: Cook the Turkey Sausage
Using the same large saucepan, add the turkey sausage and sauté over medium heat until fully cooked, about 5-7 minutes. As it cooks, break the sausage into smaller pieces. Once browned and cooked through, mix the sausage with the sautéed vegetables in the casserole dish, ensuring everything is well incorporated.

Step 5: Whisk the Egg Mixture
In a large bowl, crack open the eggs and whisk them together with milk, fresh thyme, salt, pepper, and shredded cheese until the mixture is smooth. This egg mixture will add a creaminess to your Sweet Potato Egg Casserole, binding all the flavors together beautifully.

Step 6: Assemble the Casserole
Pour the whisked egg mixture evenly over the vegetable and turkey sausage layer in the casserole dish. Gently stir the mixture using a spatula or spoon to ensure that everything is integrated and evenly distributed. This will help your casserole cook uniformly and create a delightful balance of flavors.

Step 7: Bake
Place the assembled casserole in your preheated oven and bake for about 40-45 minutes. Keep an eye on the top; it should be set and firm to the touch. If it browns too quickly, tent it with aluminum foil. The result will be a beautifully baked Sweet Potato Egg Casserole that’s fluffy and inviting.

Step 8: Cool & Serve
After baking, remove the casserole from the oven and let it cool for about 15 minutes. This resting period allows the flavors to meld and makes slicing easier. Once cooled, cut into squares and serve warm, enjoying your perfect start to the day!

Tips for the Best Sweet Potato Egg Casserole

Uniform Cutting: Ensure sweet potatoes are cut into uniform 1-inch cubes to guarantee even cooking throughout the casserole.

Avoid Overcrowding: When sautéing the vegetables, avoid overcrowding the pan; this prevents them from browning and enhances flavor.

Drain Excess Liquid: To prevent a watery casserole, drain any excess liquid from the sautéed turkey sausage and vegetables before combining.

Rest Before Serving: Letting the casserole cool for about 15 minutes after baking improves texture and makes it easier to slice and serve.

Customize Ingredients: Feel free to adapt the recipe based on your dietary needs—swap turkey sausage for a plant-based version or try different cheeses for variety.

How to Store and Freeze Sweet Potato Egg Casserole

Fridge: Store leftovers in an airtight container for up to 4 days. This way, you can savor your tasty Sweet Potato Egg Casserole throughout the week with minimal effort!

Freezer: For long-term storage, freeze individual portions in freezer-safe containers for up to 3 months. This makes for an easy, reheatable breakfast option when you’re short on time.

Reheating: To reheat, simply thaw overnight in the fridge, then warm in the oven at 350°F (175°C) until heated through, or microwave until hot. Enjoy each bite as if it were freshly baked!

Make Ahead Options

These Easy Sweet Potato Egg Casseroles are perfect for busy home cooks eager to save time! You can prepare the sautéed vegetables and turkey sausage up to 24 hours in advance. Simply store the cooled mixture in an airtight container in the refrigerator. When you’re ready to bake, whisk together the eggs, milk, thyme, salt, pepper, and cheese, then pour it over the prepared vegetable and sausage mixture. It’s essential to keep the egg mixture separate until baking to maintain that delightful fluffiness; this way, you’ll enjoy the same cozy taste just as if you made it fresh! Once you pop it in the oven, you’ll enjoy a satisfying breakfast without the morning stress.
