  • 2 pounds Smithfield Boneless Fresh Pork Sirloin Roast
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 tablespoon light olive oil
  • 4 cloves garlic minced
  • 1 tablespoon chopped fresh thyme
  • 1 tablespoon chopped fresh rosemary divided
  • ½ cup pesto sauce
  • 2 pounds red potatoes (cut into 1-inch cubes) omit for keto/low-carb


  • Preheat oven to 350° F. Sprinkle both sides of pork roast evenly with salt and pepper. Heat olive oil in skillet or dutch oven to medium-high heat. Add the pork roast and cook 4-6 minutes, or until browned, rotate and brown other side. Remove from heat.
  • In a medium bowl, stir together garlic, thyme and ½-tablespoon of rosemary. Rub over both sides of the pork roast. Cover pan and place in oven. Roast 45-60 minutes, or until internal temp reaches 145-150° F. with an instant read thermometer. Remove from pan, rub with pesto sauce and cover with foil.
  • Meanwhile: Raise oven temp to 425° F. Place potatoes on a foil-lined baking sheet. Lightly coat with olive oil, sprinkle with salt and remaining rosemary. Roast 15-20 minutes, or until browned and tender. Slice the pork roast and serve with potatoes.


You can cook the pork roast longer to make it fork tender. In a covered pot, it has a similar effect to slow cooking.
