Air fryer pork loin cooks faster than oven roasting while keeping the meat juicy inside. If you want to know exactly how long to cook loin of pork in air fryer, the short answer is 20 to 25 minutes at 375°F for a 2 to 3 pound roast. The exact time depends on the weight and thickness of your loin, plus the internal temperature you are targeting.
This guide breaks down cook times by weight, gives you a simple step by step method, and shares the few mistakes that dry out pork. Read on so your next roast comes out tender every single time.
How Long To Cook Loin Of Pork In Air Fryer
Pork loin is a lean cut, so it cooks quick and can dry out fast if you overdo it. Your air fryer circulates hot air around the meat, which browns the outside and keeps moisture locked in. That is why a pork loin that takes 50 to 60 minutes in a regular oven needs only about half that time in an air fryer.
Use the chart below as your starting point. Always confirm doneness with a meat thermometer, not just the clock.
Pork Loin Air Fryer Time Chart By Weight
- 1 pound boneless loin: 15 to 18 minutes at 375°F
- 2 pound boneless loin: 22 to 25 minutes at 375°F
- 3 pound boneless loin: 28 to 32 minutes at 375°F
- 4 pound boneless loin: 35 to 40 minutes at 375°F
- Bone-in loin roast: add 5 to 8 minutes to the times above
These times are for a loin that is roughly 3 to 4 inches thick. A thinner, flatter roast will finish sooner. A thicker one needs a few extra minutes.
What Internal Temperature Should You Aim For
Pork is safe to eat at 145°F, according to the USDA. Pull your loin out of the air fryer when the thickest part reads 140°F to 145°F. The temperature will rise another 5 degrees while the meat rests.
- 140°F to 145°F: juicy, slightly pink center, best texture
- 150°F: firm but still tender
- 160°F and up: dry and chewy, avoid this
If you prefer no pink at all, cook to 150°F. Just know the meat gets a little firmer the longer it stays in the heat.
Step By Step: Air Fryer Pork Loin Recipe
Follow these steps for a reliable roast. This method works for boneless and bone-in loins.
Step 1: Prep And Season The Pork
- Pat the loin dry with paper towels. Dry meat browns better.
- Rub with 1 tablespoon of olive oil or melted butter.
- Season all sides with salt, black pepper, garlic powder, and dried rosemary or thyme.
- Let it sit at room temperature for 15 to 20 minutes before cooking.
A dry rub with a little sugar helps the crust caramelize. Keep the sugar amount small so it does not burn.
Step 2: Preheat The Air Fryer
Set your air fryer to 375°F and let it run for 3 to 5 minutes. Preheating gives you a better sear and more even cooking. If your model has no preheat setting, just run it empty for a few minutes.
Step 3: Place The Loin In The Basket
Put the loin fat side up if it has a fat cap. Leave space around the meat so air can flow. Do not stack or crowd the basket. For a roast larger then 3 pounds, cut it in half so both pieces cook evenly.
Step 4: Cook And Flip Halfway
- Cook at 375°F for the time listed in the chart above.
- Flip the loin with tongs at the halfway mark.
- Start checking the internal temperature 5 minutes before the estimated finish time.
- Remove when the center hits 140°F to 145°F.
Every air fryer runs a bit different. Yours may run hot or cool, so the thermometer is your best friend here.
Step 5: Rest Before Slicing
Move the loin to a cutting board and cover it loosely with foil. Let it rest for 10 minutes. This step lets the juices settle back into the meat. Skip it and your slices will leak juice onto the board instead of staying in the pork.
Slice against the grain into half inch pieces. That keeps each bite tender.
Tips For Juicy Pork Loin In The Air Fryer
A few small habits make a big difference in the final result.
- Brine the loin for 30 to 60 minutes in salt water for extra moisture.
- Do not overcook. Pull it early and let carryover heat finish the job.
- Use a meat thermometer every time. Guessing leads to dry pork.
- Add a splash of broth or apple juice to the basket for steam, if your model allows it.
- Let the meat rest before slicing. This is not optional.
- Reheat leftovers at 300°F for 5 minutes only, or they dry out.
Common Mistakes To Avoid
- Cooking from frozen without adding time. Thaw first for best results.
- Piling vegetables under the loin. They block airflow and slow cooking.
- Trusting the recipe time over your thermometer.
- Slicing right away and losing all the juice.
How Long To Cook Pork Loin At Different Temperatures
Most recipes call for 375°F, but you can adjust based on the result you want.
- 350°F: 25 to 30 minutes for a 2 pound loin, softer crust
- 375°F: 22 to 25 minutes for a 2 pound loin, balanced browning
- 400°F: 18 to 22 minutes for a 2 pound loin, crispier outside
Higher heat gives a darker crust but less margin for error. If you are new to air frying pork, stay at 375°F.
Boneless Vs Bone-In Loin
Boneless loin cooks faster and slices cleaner. Bone-in loin has more flavor and stays moist a bit longer, but it needs 5 to 8 extra minutes. Check the temperature near the bone, since that area cooks slowest.
Leftovers And Storage
Store sliced pork in an airtight container in the fridge for up to 4 days. For longer storage, freeze slices in a freezer bag for up to 3 months. Reheat gently so the meat does not toughen.
Final Word On Air Fryer Pork Loin
So, how long to cook loin of pork in air fryer? Plan on 20 to 25 minutes at 375°F for a 2 to 3 pound roast, then adjust by weight and always check with a thermometer. Pull it at 140°F to 145°F, rest it for 10 minutes, and slice against the grain.
Do that and you get a juicy, golden pork loin on a weeknight with almost no cleanup. Try the time chart once, note how your air fryer behaves, and you will have your own perfect number from then on.
