Ingredients

Vegetables

  • 2 tablespoons avocado oil, divided
  • 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

Topping

  • 1/2 cup grated mozzarella cheese

Instructions

  1. Preheat and Prepare Vegetables: Preheat your oven to 375°F (190°C). Heat 1 tablespoon of avocado oil in a large skillet over medium heat. Add the chopped yellow onion, green bell pepper, and cubed sweet potatoes. Sauté for about 10-12 minutes until the vegetables are tender and the onion is translucent. Add the minced garlic during the last minute to avoid burning.
  2. Cook Turkey Sausage: Push the vegetables to the side of the skillet and add the turkey sausage. Cook the sausage, breaking it up with a spoon, until browned and fully cooked through, approximately 7-8 minutes. Mix the sausage with the vegetables thoroughly.
  3. Combine Egg Mixture: In a large bowl, whisk together the eggs, milk, dried thyme, salt, and pepper until well combined.
  4. Assemble the Casserole: Grease a 9×13 inch baking dish with the remaining 1 tablespoon of avocado oil. Transfer the cooked sausage and vegetable mixture into the baking dish, spreading it evenly. Pour the egg mixture over the ingredients in the dish. Sprinkle the grated mozzarella cheese evenly on top.
  5. Bake the Casserole: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the eggs are set and the top is lightly golden. To check for doneness, insert a knife in the center – it should come out clean.
  6. Rest and Serve: Remove the casserole from the oven and let it rest for 5 minutes before slicing. Serve warm for a filling breakfast or brunch option.

Notes

  • You can substitute plant-based milk such as almond or oat milk to make this dairy-free-friendly.
  • For a vegetarian version, replace turkey sausage with a plant-based sausage or sautéed mushrooms.
  • Leftovers can be refrigerated for up to 3 days and reheated in the microwave or oven.
  • Adding chopped fresh herbs like parsley or chives on top before serving adds a fresh flavor boost.
  • Make sure to cook the sausage fully to ensure food safety and best taste.
