How to Make High-Protein Turkey Sweet Potato Casserole
Creating this delicious casserole is a simple process involving a quick boil, a flavorful sauté, and a final trip to the oven to melt everything together into golden perfection.
Ingredients
- 1 lb ground turkey (93% lean)
- 2 large sweet potatoes (peeled and cubed)
- 1 small onion (diced)
- 1 bell pepper (diced)
- 2 cloves garlic (minced)
- 1 tsp smoked paprika
- 1/2 tsp cumin
- Salt and pepper to taste
- 1 cup shredded mozzarella cheese (optional)
- 1 tbsp olive oil
- Fresh parsley for garnish
Directions
Step 1: Preparation and Preheating
Preheat your oven to 400°F (200°C). While the oven is warming up, prepare your baking dish by lightly greasing it with a small amount of oil or non-stick spray.
Step 2: Boil the Sweet Potatoes
Place the cubed sweet potatoes in a large pot of salted water. Bring to a boil and cook for about 10 minutes, or until the cubes are fork-tender. Drain the water and set the potatoes aside.
Step 3: Sauté the Aromatics and Turkey
In a large skillet, heat the olive oil over medium heat. Add the diced onion and bell pepper, sautéing until they begin to soften. Stir in the minced garlic for about one minute until fragrant. Add the ground turkey, smoked paprika, cumin, salt, and pepper. Cook the turkey until it is browned and cooked through, breaking it apart with a spatula as it cooks.
Step 4: Prepare the Casserole Base
Take half of your boiled sweet potato cubes and mash them in a bowl. Mix the mashed potatoes into the cooked turkey mixture until well combined. This creates a creamy texture without the need for added milk or cream.
Step 5: Layer and Bake
Spread the turkey and mashed potato mixture evenly into your prepared baking dish. Top the mixture with the remaining whole sweet potato cubes. Sprinkle the shredded mozzarella cheese over the top if you are using it. Place the dish in the oven and bake for 15-20 minutes, or until the cheese is bubbly and starting to turn golden brown.
Step 6: Garnish and Serve
Remove the casserole from the oven and let it rest for 5 minutes. Garnish with fresh parsley before serving to add a pop of color and freshness.
How to Serve High-Protein Turkey Sweet Potato Casserole
This casserole is a complete meal on its own, but you can elevate it with a few simple sides. A crisp green salad with a light vinaigrette balances the sweetness of the potatoes perfectly. You can also serve it with a side of steamed broccoli or roasted green beans for extra volume and nutrients.
How to Store High-Protein Turkey Sweet Potato Casserole
Store any leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, you can use the microwave for 1-2 minutes or place it back in a 350°F oven for about 10 minutes to maintain the texture of the potatoes and cheese.
Expert Tips for Perfect High-Protein Turkey Sweet Potato Casserole
For the best results, make sure you don’t over-boil the sweet potatoes; you want the ones on top to hold their shape during the baking process. If you want a bit of a kick, add a pinch of cayenne pepper or chili flakes to the turkey while it browns. Always use a lean ground turkey to prevent the casserole from becoming too greasy.

Delicious Variations
You can easily swap the ground turkey for ground chicken or even lean ground beef. For a dairy-free version, simply omit the mozzarella or use a plant-based cheese alternative. If you want more vegetables, stir in some baby spinach or kale to the turkey mixture just before putting it into the baking dish; the heat will wilt the greens perfectly.
