Pat the turkey dry with a paper towel. Then, lightly season both sides with salt and pepper.
In a small mixing bowl, stir the turkey seasoning, garlic powder, and onion powder until thoroughly combined. Generously season the meat with part of the seasoning until well coated. Set it aside.
Mix the remaining seasoning with the flour in a shallow bowl. Dredge the turkey chops with the flour mixture until thoroughly coated, shake off the excess, and place them on a clean plate or board. Allow to rest for about 5 minutes. Reserve 2 tablespoons of the mixture for the gravy.
Heat a cast iron skillet on medium-high, then add a drizzle of oil.
Place chops in the hot oil and cook for 4-5 minutes or until golden. Flip them over and cook for another 4 minutes.
Once they're ready, transfer them to a paper-towel-lined plate and set aside.
Pour the remaining oil into the same pan, then sauté the onion, mushrooms, garlic, and thyme for 5-7 minutes, or until the onion is slightly browned and the mushrooms have released their liquid. Transfer to a plate and set aside.
Add butter to the cast iron pan. Once melted, add 2 tablespoons of seasoned flour, turn the heat down to low, and whisk until the butter absorbs the flour and barely starts to brown.
Whisk in the chicken broth and continue stirring until the gravy thickens slightly. Add more chicken broth if it gets too thick. Season with salt and pepper to taste.
Stir in the onions and mushrooms, return the turkey chops to the pan, and spoon some of the gravy over them. Put the lid on and simmer for 15 minutes.
Once the turkey is done, garnish with parsley and serve over mashed potatoes, rice, or pasta. Enjoy.
