Vegetables
- 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 & Alternatives
- 1/2 cup milk (plant-based milk can be substituted)
- 1/2 cup grated mozzarella cheese
Oils & Seasonings
- 2 tablespoons avocado oil
- 1 teaspoon dried thyme
- 1 teaspoon salt
- 1/2 teaspoon pepper
- Preheat Oven: Preheat your oven to 375°F (190°C) to ensure it is hot enough for baking the casserole evenly.
- Sauté Vegetables and Sausage: Heat 2 tablespoons of avocado oil in a large skillet over medium heat. Add the chopped yellow onion, green bell pepper, and minced garlic, sautéing until softened and fragrant, about 5 minutes. Then add the turkey sausage and cook, breaking it up with a spoon, until fully browned and cooked through, about 7-8 minutes.
- Prepare Sweet Potatoes: While the sausage cooks, peel and cube the sweet potatoes if not already done. Add the cubed sweet potatoes to the skillet with the cooked sausage and vegetables, stirring to combine. Cook for another 5-7 minutes, allowing the sweet potatoes to start softening.
- Mix Egg Mixture: In a large mixing bowl, whisk together the 10 eggs, 1/2 cup milk, dried thyme, salt, and pepper until fully blended and slightly frothy.
- Assemble the Casserole: Transfer the sausage, vegetable, and sweet potato mixture to a greased baking dish. Pour the egg mixture evenly over the top. Sprinkle the grated mozzarella cheese evenly on top to create a cheesy crust.
- Bake: Place the casserole dish in the preheated oven and bake for 35-40 minutes, or until the eggs are fully set and the cheese is golden and bubbly.
- Rest and Serve: Remove from oven and let rest for 5-10 minutes before slicing. This allows the casserole to set for easier serving. Serve warm and enjoy!
