• Milk (or plant-based milk): Helps make the egg mixture luscious and smooth.

How to Make Easy Sweet Potato Egg Casserole

Step 1: Preheat Oven and Prepare the Baking Dish

Start by heating your oven to 350°F (175°C), the perfect temperature for an even bake. While waiting, chop your vegetables to ready them for sautéing. Don’t forget to grease your 9×13-inch casserole dish – this will keep your delicious creation from sticking and make cleaning up easier.

Step 2: Cook the Vegetables

Heat some avocado oil in a Dutch oven or large saucepan until it’s nice and hot. Toss in the chopped onion, green bell pepper, and sweet potatoes, and sauté for about 8 to 9 minutes, allowing them to soften and develop their flavors. In the final minutes, add minced garlic to release its fragrant aroma. Once cooked, spread this colorful veggie mixture evenly in the prepared casserole dish.

Step 3: Cook the Sausage

Using the same pan, add your turkey sausage and cook it until fully browned and no longer pink inside. Break it up into smaller pieces as it cooks to ensure it heats through evenly. Mix the cooked sausage directly into the casserole dish with the vegetables, blending those wonderful flavors together right at the base.

Step 4: Prepare the Egg Mixture

In a separate bowl, whisk together eggs, milk, dried thyme, salt, pepper, and mozzarella cheese until well combined. This mixture will become the creamy, custardy binder of your casserole, ensuring each slice is packed with flavor and richness.

Step 5: Combine and Bake

Pour the egg mixture over your sausage and veggie base, stirring gently to distribute the eggs evenly throughout the dish. Place the casserole in your preheated oven and let it bake for 40 to 45 minutes until the center is firm. If you notice the top browning too quickly, tent it lightly with foil to protect the surface while the inside finishes cooking.

Step 6: Cool and Serve

Once baked, remove the casserole from the oven and allow it to cool for about 15 minutes. This resting time allows the flavors to settle and makes slicing easier, so you get perfect squares every time you serve. Then, dig in and enjoy the cozy, satisfying taste of this Easy Sweet Potato Egg Casserole!
