Ingredients

Scale

Vegetables

2 tablespoons avocado oil
1/2 large yellow onion, chopped
1 green bell pepper, chopped
5 cups cubed sweet potatoes
3 garlic cloves, minced

Protein

1 pound turkey sausage

Egg Mixture

10 eggs
1/2 cup milk (plant-based milk can be substituted)
1 teaspoon dried thyme
1 teaspoon salt
1/2 teaspoon pepper
1/2 cup grated mozzarella cheese

Instructions

Preheat Oven and Prepare the Baking Dish: Preheat your oven to 350°F (175°C). While the oven is heating, chop all vegetables. Grease a 9×13-inch casserole dish to prevent sticking during baking.
Cook the Vegetables: Heat avocado oil in a Dutch oven or large saucepan until hot. Add chopped onion, green bell pepper, and sweet potatoes. Cook for 8-9 minutes, stirring occasionally, until the vegetables begin to soften. Add minced garlic in the last 1-2 minutes and sauté. Remove vegetables from the pan and spread evenly in the prepared casserole dish.
Cook the Sausage: Using the same Dutch oven, add turkey sausage and sauté until fully cooked, breaking it into small pieces as it cooks. Add the cooked sausage to the vegetables in the casserole dish and stir to combine well.
Prepare the Egg Mixture: In a mixing bowl, whisk together eggs, milk, dried thyme, salt, pepper, and shredded mozzarella cheese until smooth and thoroughly combined.
Combine and Bake: Pour the egg mixture over the vegetable and sausage combination in the casserole dish. Stir gently to evenly distribute the egg mixture. Place the dish in the preheated oven and bake for 40-45 minutes, until the center is firm and set. If the top browns too quickly, cover loosely with foil to prevent burning.
Cool and Serve: Remove casserole from the oven and let cool for 15 minutes to allow flavors to settle and to make it easier to cut and serve.

Notes

You can substitute plant-based milk for regular milk to make this dish dairy-free.
Use turkey sausage for a leaner protein option; pork sausage can also be used if preferred.
The casserole can be prepared the night before and baked fresh in the morning.
Leftovers store well in the refrigerator for up to 3 days and reheat quickly.
Covering loosely with foil during baking helps prevent over-browning the top.
