Ingredients

Scale

Vegetables and Aromatics

  • 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
  • 10 eggs

Dairy and Seasonings

  • 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

  1. Preheat Oven and Prepare the Baking Dish: Preheat your oven to 350°F (175°C). While the oven is heating, chop all your vegetables. Grease a 9×13-inch casserole dish to prevent sticking during baking.
  2. Cook the Vegetables: Heat the avocado oil in a Dutch oven or large saucepan until hot. Add the chopped onion, green bell pepper, and cubed sweet potatoes. Cook for 8-9 minutes, stirring occasionally, until the vegetables begin to soften. In the last 1-2 minutes, add minced garlic and sauté briefly. Remove the vegetables and spread evenly in the prepared casserole dish.
  3. Cook the Sausage: Using the same pan, add the turkey sausage and cook until fully browned and cooked through, breaking it into small pieces while cooking. Add the cooked sausage to the vegetables in the casserole dish and stir well to combine.
  4. Prepare the Egg Mixture: In a mixing bowl, whisk together the eggs, milk, dried thyme, salt, pepper, and grated mozzarella cheese until smooth and thoroughly mixed.
  5. Combine and Bake: Pour the egg mixture over the vegetable and sausage mix in the casserole dish. Stir gently to evenly disperse the eggs throughout. Place the casserole in the preheated oven and bake for 40-45 minutes, or until the center is firm. If the top begins to brown too much, loosely cover with foil halfway through baking to prevent burning.
  6. Cool and Serve: Remove the casserole from the oven and allow it to cool for about 15 minutes before serving. This resting time helps the flavors meld and makes the casserole easier to cut and serve. Enjoy your delicious hearty breakfast casserole!

Notes

  • You can substitute plant-based milk such as almond or oat milk to make the dish dairy-free.
  • Cover loosely with foil if the top browns too quickly while baking.
  • For extra flavor, consider adding fresh herbs like parsley or chives before serving.
  • This casserole can be made a day ahead and refrigerated; reheat before serving.
  • Use turkey sausage for a leaner protein option; pork sausage can be used for richer flavor.
