Tips for Cooking a Pork Loin Roast in the Oven
For the best results when cooking a pork loin roast in the oven, pay attention to the tips, guidelines, and cooking instructions we have provided below:
The ideal amount to cook – 6 to 8 persons can be served using a 3- to 4-pound pork loin roast. However, it’s not a bad idea to make a bit more of the roast than you need and then enjoys the leftovers all week (they’re delicious in a sandwich and herbed mayo).
Important seasoning tip – Seasonings will stick even better if you score the top of the roast in an X pattern with your knife. You don’t need to cut all the way through the roast; just enough of a cut to make grooves for the seasonings to sit in.
Sear your pork loin roast – Although it’s really nice to sear your pork loin roast before baking it in the oven, we don’t think it’s necessary when there’s no skin on the roast. When your pork loin roast has no skin, we recommend coating it with brown sugar and butter and broiling it shortly before slicing to achieve the caramelized crust effect that a good sear would provide.
Ideal cooking duration – To prepare a pork loin safely, cook it for around 25 minutes for every pound, assuming the roast weighs 3 to 4 pounds. This figure will need to change significantly if you’re cooking a full pork loin roast (about 8 to 10 pounds). Reduce the heat of the oven to 350 degrees Fahrenheit and cook for roughly 10 minutes per pound for a whole pork loin.
Ideal internal temperature – It’s best to cook your pork to a safe internal temperature of 145 to 160 degrees, according to the National Pork Board. Even though it used to be higher, this temperature range is a perfectly safe one to cook your pork roast. You could also choose to stick to 150 degrees doneness and leave the pork roast to rest for 5 to 10 minutes before you serve it because a roast will continue to cook through even after it is removed from the oven.

- 3– pound pork loin
- 1 tablespoon of olive oil
For the Spice Rub

- 1 pound of brussels sprouts (cut in half)
- 1 pound of butternut squash, peeled, seeds cleaned out, and cut into 1-inch cubes (you can also opt for pre-cut butternut squash)
- Preheat the oven to 375 degrees Fahrenheit. Set aside a rimmed baking sheet lined with parchment paper or aluminum foil. Using paper towels, pat the pork loin dry.
- Combine all the seasoning ingredients for the spice rub (paprika, onion powder, garlic powder, rosemary, thyme, salt, and pepper) in a small mixing bowl.
- Using frying spray, lightly coat the pork loin. This will aid in the sticking of the spice mixture.
- Apply the spice mixture on the pork loin and massage it all over it.
- Sear the pork loin in olive oil over medium heat until it gets adequately browned on all sides, this should take about 3 to 5 minutes for each side of the roast. Set aside the pork loin on the prepared baking sheet, making sure that the fat-layer side is facing up.
- In a bowl, mix garlic, soy sauce, honey, mustard, and oil together; whisk the mixture until it is well incorporated. If the sauce is overly thick, drizzle with a little extra soy sauce or oil. Measure 2 tablespoons of the resulting mixture and set it aside for the vegetables.
- Brush the pork loin with the remaining honey mixture. Cook the pork loin roast for 25 minutes at 350°F.
- Meanwhile, combine the vegetables with the honey mixture you set aside, as well as a tablespoon of oil. Take the pork roast out of the oven and arrange the veggies in a single layer around it.
- Cover the pork with foil to prevent the top from burning while the interior aspect of the meat keeps cooking. Return the pork loin to the oven and cook for another 25 to 30 minutes, or until the internal temperature reaches 145°F. Check for doneness with an Instant Read Thermometer. Halfway through the cooking process, stir the vegetables.
- Take the baking sheet out of the oven and cover the meat and vegetables loosely with foil; set aside for 10 minutes. Slice the pork and serve with vegetables.
