Vegetables
- 1/2 large yellow onion, chopped
- 1 green bell pepper, chopped
- 5 cups cubed sweet potatoes
- 3 garlic cloves, minced
Meat
Dairy & Eggs
- 10 eggs
- 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 and Prepare the Baking Dish: Preheat your oven to 350°F (175°C). While the oven heats, chop all your vegetables and 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 the chopped onion, green bell pepper, and sweet potatoes. Cook for 8-9 minutes, stirring occasionally, until the vegetables start to soften. Add minced garlic during the last 1-2 minutes and sauté. Remove cooked vegetables and spread them evenly across the bottom of the greased casserole dish.
- Cook the Sausage: Using the same Dutch oven, add the turkey sausage. Sauté until fully cooked, breaking it into small pieces as it cooks. Once done, add the cooked sausage over the layer of vegetables in the casserole dish.
- Prepare the Egg Mixture: In a large bowl, whisk together the eggs, milk, dried thyme, salt, and pepper until fully combined.
- Assemble and Bake: Pour the egg mixture evenly over the vegetables and sausage in the casserole dish. Sprinkle grated mozzarella cheese on top. Bake in the preheated oven for 35-40 minutes, or until the eggs are set and the top is lightly golden.
- Cool and Serve: Allow the casserole to cool for 5-10 minutes before slicing. Serve warm and enjoy your protein-packed sweet potato egg casserole!
Notes
- You can substitute the turkey sausage with plant-based sausage for a vegetarian version, although vegetarian diet classification would then apply.
- Plant-based milk such as almond or oat milk can replace regular milk to make this recipe dairy-free.
- For added flavor, sprinkle some crushed red pepper flakes or chopped fresh herbs like parsley before serving.
- Leftovers can be stored covered in the refrigerator for up to 4 days.
- This casserole freezes well; thaw overnight in the fridge before reheating.
