How to Make Ground Turkey Sweet Potato Casserole (Step-by-Step)
1. Cook the Sweet Potatoes
Bring a pot of salted water to a boil. Add the cubed sweet potatoes and cook for 10–12 minutes, or until fork-tender. Drain well, then mash with butter and milk until smooth. Season with salt, pepper, and nutmeg. Set aside.
2. Sauté the Turkey Mixture
Meanwhile, heat olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 3 minutes. Stir in the garlic and bell pepper, cooking for another 2 minutes. Add the ground turkey and cook until browned, breaking it apart with a spatula.
Next, stir in the tomato paste, paprika, thyme, salt, and pepper. Pour in the broth and let it simmer for 3–5 minutes to blend the flavors. The mixture should be saucy but not runny.
3. Assemble the Casserole
Preheat the oven to 375°F (190°C). Lightly grease an 8×8-inch baking dish. Spread the turkey mixture evenly across the bottom. Spoon the mashed sweet potatoes over the top and smooth them into an even layer. Sprinkle with cheese, if using.
4. Bake Until Golden
Bake uncovered for 20–25 minutes, or until heated through and the cheese is melted and slightly golden.
5. Serve and Enjoy
Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley and serve warm alongside a crisp salad or steamed vegetables.
