• Eggs: The binding element creating that rich, fluffy texture every great casserole needs.
• Milk (or plant-based milk): Lightens the eggs while adding moisture for a perfectly set casserole.
• Dried thyme: A fragrant herb that elevates the dish with subtle earthy notes.
• Salt and pepper: Essential seasonings that bring all the flavors together.
• Mozzarella cheese: Melts into gooey goodness, creating little pockets of cheesy delight throughout the casserole.

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) so it’s ready when you are. While it warms up, chop the onion, green pepper, and sweet potatoes into bite-sized pieces. Make sure to grease a 9×13-inch casserole dish well to stop the ingredients from sticking during baking—that way, clean-up will be a breeze later on.

Step 2: Cook the Vegetables

Heat avocado oil in a Dutch oven or large saucepan until shimmering. Add the chopped onion, green bell pepper, and sweet potatoes, sautéing them for about 8-9 minutes. Keep stirring every now and then until the veggies soften and become fragrant. Toss in the minced garlic in the last couple of minutes to coax out its robust flavor without burning it. Then, spread the cooked vegetables evenly in your prepared casserole dish.

Step 3: Cook the Sausage

Use the same pan to cook the turkey sausage so you keep all those wonderful browned bits from the veggies. Break the sausage into small chunks while it cooks until it’s no longer pink and fully cooked through. Then stir it into the vegetables in the casserole dish, making sure everything is well combined to create that perfect savory base.

Step 4: Prepare the Egg Mixture

Now whisk together the eggs, milk, dried thyme, salt, pepper, and mozzarella cheese in a mixing bowl. You want a smooth, uniform mixture that will soak into the veggies and sausage, creating those custardy pockets that make this casseroles so irresistible.

Step 5: Combine and Bake

Pour your egg mixture over the veggie and sausage layers in the casserole dish. Give it a gentle stir just to distribute the eggs evenly, but not so much that everything gets mushy. Place the dish in your preheated oven and bake for 40-45 minutes. When the center feels firm to the touch, your casserole is ready. If the top begins to brown too much midway through baking, cover loosely with foil to keep it from burning.

Step 6: Cool and Serve

Once out of the oven, let your Easy Sweet Potato Egg Casserole cool for 15 minutes. This resting time allows the casserole to set up perfectly, meaning it will slice neatly and the flavors will meld beautifully, ready to wow anyone lucky enough to have a slice.

How to Serve Easy Sweet Potato Egg Casserole

Side Dishes
