Pork Loin

  • 3 lb pork loin roast boneless
  • 2 Tbsp olive oil
  • 1 tsp garlic powder
  • ½ tsp onion powder
  • ½ tsp salt
  • ½ tsp ground black pepper
  • 1 tsp smoked paprika


  • 1 Tbsp olive oil
  • 1 lb brussel sprouts halved
  • 2 medium sized sweet potatoes peeled and diced into 1’’ pieces
  • 1 tsp garlic powder
  • ½ tsp black pepper


  • Preheat oven to 375 degrees F.
  • Line a rimmed baking sheet with aluminum foil or parchment paper and set aside. I recommend using a half sheet pan.
  • In a small bowl combine the seasonings for the pork; garlic powder, onion powder, salt, black pepper and smoked paprika.
  • Rub the entire pork loin with spice mixture.
  • In a frying pan heat 2 Tbsp of olive oil over medium heat. When olive oil is hot place pork loin in pan and sear until all sides are browned; about 2-3 minutes per side.
  • Transfer pork loin to prepared baking sheet with the fat-layer up.
  • Place pork loin in preheated oven at 375 degrees F for 25 minutes.
  • While pork is cooking toss the vegetables along with olive oil and seasonings in a mixing bowl.
  • Pull pork loin out of oven after 25 minutes and add the vegetables all around it in one layer.
  • Place pork loin back in oven and cook 25-30 additional minutes or until the internal temperature of the pork loin reaches 145 degrees F.
  • Remove the baking sheet from the oven and loosely cover with foil. Let rest 3 minutes.
  • Cut the pork in slices and serve with vegetables.



  • Make sure you cook the roast cap side up.
  • Refrigerate leftovers for up to 3 days.
  • Make sure you are using a pork loin and not pork tenderloin. Pork Loin is a thicker and wider cut usually found with a fatty layer on top. Pork Tenderloin is a long, thinner piece of pork.
  • For this pork loin roast we recommend cooking it to 145 degrees F. This is a perfectly safe temperature for this cut of meat. Here is a quick chart for reference on other cuts of pork and their recommended cooking temperature.
