To prepare a steakhouse pecan pork chops recipe, you'll need: 1 pound boneless, skinless pork tenderloin trimmed of fat, 1 cup chopped pistachios, 2 teaspoons each ground cinnamon and nutmeg, 1/4 teaspoon each kosher salt and ground black pepper, and 2 tablespoons olive oil. Preheat the oven to 450?F (232?C) and grease two 8-inch x 4-inch baking pans with non-stick cooking spray. Place the pork in the pan and cook, turning occasionally, until the meat is no longer pink, 20 to 25 minutes. Remove from the heat and let rest 5 minutes before serving.
