Heat olive oil in a cast iron skillet over medium-high heat.
Add ground turkey and minced garlic. Cook for about 5 minutes, breaking the turkey apart as it browns.
Stir in diced onions and yellow peppers. Cook until onions become soft and fragrant.
Add diced sweet potatoes, salt, pepper, and red chili flakes. Mix well.
Cover the skillet and cook until sweet potatoes are tender, stirring occasionally. Add a splash of water if needed to soften faster.
Preheat oven to 400°F (200°C).
Once the sweet potatoes are cooked, sprinkle mozzarella cheese over the skillet.
Transfer the skillet to the oven and bake until the cheese melts.
Remove, garnish with parsley, and serve warm.
This Ground Turkey Sweet Potato Skillet comes together easily and delivers rich flavor in every bite.
