A Whole30 and paleo Tex-Mex Taco Casserole – comfort food at its finest! It is filled with spicy ground turkey, vegetables, and topped with sweet potato!



For the casserole:

  • 1 1/2 pounds ground turkey
  • 2 carrots, diced
  • 2 parsnips, diced
  • 1/2 red onion, diced
  • 2 bell peppers, diced
  • 4 cloves garlic, minced
  • 14.5 ounce can organic diced tomatoes
  • 2 handfuls spinach
  • 2 Tablespoons ghee, divided
  • 1/2 teaspoon salt

For the taco seasoning:

  • 1 teaspoon salt
  • 2 teaspoons cumin
  • 1 teaspoon chili powder
  • 1/2 teaspoon smoked paprika
  • 1 teaspoon onion powder
  • 1/2 teaspoon cayenne pepper
  • 1 teaspoon dried oregano
  • 1/2 teaspoon black pepper

For the spiralized sweet potatoes:

  • 2 large sweet potatoes, spiralized
  • 2 Tablespoons ghee
  • 1/2 teaspoon chili powder
  • 1/2 teaspoon ground cumin
  • Optional garnish: fresh cilantro, avocado, and hot sauce


  1. Preheat oven to 350 degrees F.
  2. Prepare your vegetables: Chop all vegetables. In a large skillet, (I use my 12 inch cast iron) heat 1 Tablespoon of ghee over medium heat. Add all of the vegetables and cook until tender. Remove from skillet and set aside.
  3. Prepare your meat: Bring skillet back up to medium-high heat and add 1 Tablespoon of ghee. To the skillet, add the ground turkey and all of the seasonings. Cook until no longer pink.
  4. While the meat is cooking, place the spiralized sweet potatoes in a large bowl. Melt remaining 2 Tablespoons of ghee and pour over potatoes. Sprinkle with chili powder and cumin; toss to combine.
  5. Add the cooked vegetables back into the skillet with the browned turkey. Stir to combine.
  6. Spray a large casserole dish (4 quart or 9×13 inch pan) with coconut oil cooking spray. Add the meat and veggie mixture to the dish and top with spiralized sweet potato.
  7. Cover with a lid or tin foil and cook for 30 minutes. Remove foil and cook for an additional 10 minutes.
  8. To serve, top with fresh cilantro, avocado, and hot sauce! If you aren’t keeping this Paleo, add a dollop of Greek yogurt and sprinkle with cheddar cheese.
