What’s not to like about an Instant Pot pork loin roast? It’s ready to eat in about half the time it would take to roast in the oven. It turns out juicy and flavorful. And you only get one pan dirty.
Pork loin roasts are frequently on sale so they are an economical meat to buy. A two and a half to three pound roast serves a crowd (about 8) and a pork loin roast is easy to serve. The roast can rest while you’re tending the final details of dinner, it slices neatly and easily, and has a nice presentation.
If you’ve had bad luck cooking pork loin roasts, give this recipe a try. My mom always complains that her pork loin roasts are too dry, tough, and flavorless, whether baked in the oven or cooked all day in the slow cooker. What sounded like a promising recipe alway ended up a disappointment in reality.
BUT I’m happy to say she loves this pork loin roast. I think she’s a convert to the Instant Pot. I’m happy about that, because my sister and I bought it for her.
About This Recipe
The beauty of cooking pork loin roasts in your Instant Pot is that:
- You only get one pan dirty
- You don’t have to turn your oven on.
How does a pork roast cooked in an Instant Pot taste?
Delicious! Juicy, tender, and flavorful–just how you want it to be.
The pan juices are tangy and delicious with balsamic vinegar, Worcestershire sauce, and brown sugar combined with the succulent pork drippings. I like to serve the slices au jus but you could also thicken the drippings to make a gravy.
How To Make It
Begin by taking your pork loin roast out of the fridge for twenty minutes to a half hour. Let it set on the counter to warm up a bit. Season it well and then sear it right in your Instant Pot, letting it get nice and brown. Take the pork roast out and place it on a plate.
Pour broth into the pot and scrape all the brown bits off the bottom. This is important because otherwise the Instant Pot will think something’s burning in there and shut off in the middle of the cooking time. You don’t want that to happen!
Add a bit of balsamic vinegar, Worcestershire sauce, and brown sugar to the pot and then put your roast in. You’ll roast it on high pressure for 27 minutes, with 15 minutes natural release.
When the pork loin roast is finished cooking, take it out of the pot and let it rest for at least 15 minutes before slicing. Don’t skip this step! Why not? It’s essential to have this rest time because the internal temperature of the roast will continue to rise as it rests. The optimal internal temperature is 145°F.
The pan juices can be simmered briefly to reduce, making a sauce to serve drizzled over the pork. Garnish with chopped fresh parsley or rosemary. You won’t need to serve your roast with additional gravy because the pork is flavorful and juicy. I love sautéed mushrooms with wine and garlic as a side. Caramelized onions are a wonderful embellishment for pork roast.
Try serving pork roast with roasted sweet potatoes, or roasted green beans, or broccoli. It is delicious with any kind of squash.
While their names are similar, these two cuts of pork are very different and are not interchangeable in terms of cooking methods.
Pork loins are larger, usually 4-5 pounds. A fat cap runs along one entire side of the loin. The meat is lighter in color and is less expensive. You can roast pork loins whole or cut them into slices to grill or fry.
Pork tenderloins are one to one and half pounds. They are longer and thinner, and darker red in color. Tenderloins are the most tender cut of pork, and are leaner than pork loins. Tenderloins are more expensive per pound and do not take as long to cook. They can be roasted whole or cut into slices and seared.
Because pork loins do not have a lot of fat marbling, they tend to become tough and dry when overcooked. Ideally, the internal temperature should be around 145ºF. Remember that the pork will continue to cook as it rests.
It helps to have the pork at room temperature before cooking it. If it’s icy cold, the outside will get overcooked and dry before the inside gets done.
Searing the roast before cooking helps to retain the juice and also adds a lot of flavor.
Make It Your Own
- Vary the sauce ingredients. Want to make a honey garlic sauce? Substitute honey for the brown sugar and add minced garlic or increase the amount of garlic powder. Experiment with your favorite seasonings. Soy sauce, rice vinegar, and ginger are good.
- Use your favorite rub on the pork before searing it. Try this easy spice rub for pork. Or make a BBQ flavored rub and serve the pork with BBQ sauce on the side.
- Rather use your crockpot? We love this slow cooker pork loin with balsamic glaze.
If you’re not serving a crowd, put the cooked slices in a freezer bag or container, and save them for a busy day when you don’t have much time to cook. A perfect meal prep idea! Instant Pot Turkey Breast is another one of my favorite meal prep recipes.
The pork should last 3 to 4 days in the fridge or up to 3 months in the freezer. For best results, thaw frozen pork overnight in the refrigerator. Reheat gently in the microwave, or lightly fry until warm.

Instant Pot Pork Loin Recipe
Ingredients
- 2 to 3 pounds boneless pork loin roast (see note)
- 1 teaspoon kosher salt
- ½ teaspoon coarse ground black pepper

- 1 teaspoon balsamic vinegar
- 1 teaspoon Worcestershire sauce
- 1 teaspoon light or dark brown sugar
- fresh parsley or rosemary for serving
Instructions

- Set Instant Pot to Saute. When hot, add oil and add pork. Brown pork on both sides, 4 to 5 minutes per side. Press cancel on the Instant Pot and remove pork to a plate.2 to 3 pounds boneless pork loin roast, 1 tablespoon olive oil
- Add broth to Instant Pot and scrape all bits from the bottom of the pot. Add vinegar, Worcestershire sauce, and brown sugar.1 cup unsalted chicken broth, 1 teaspoon balsamic vinegar, 1 teaspoon Worcestershire sauce, 1 teaspoon light or dark brown sugar
- Place trivet in the Instant Pot and set pork, fat side up, on top of trivet.
- Secure lid, turn valve to seal.
- Set pressure cooker to “pressure cook” or “manual” (depending on model), high pressure, for 27 minutes. Let pressure release naturally (in other words, leave it alone) for 15 minutes before releasing remaining pressure, if any, by turning valve to “vent.”
- Transfer pork to a cutting board or plate and let rest for 15 minutes. This step is essential. The internal temperature of the roast will continue to rise as it rests. Check temperature of pork using an instant read thermometer in the center of the roast. It should read 145ºF.
- Meanwhile, switch Instant Pot back to “Saute” and simmer pan juices to form a sauce.
- Slice pork and serve with pan juices.
Notes
- Often, pork loin roasts are larger than 2 to 3 pounds; they can run 7 to 10 pounds. Most Instant Pots won’t accommodate such a large roast. If you buy a large roast, cut it in half for this recipe and freeze the other half to prepare for a later meal.
- Nutrition information is calculated with a 3 pound roast.
- Leftover pork can be refrigerated for 3 to 4 days. Frozen pork will keep for up to 3 months.

Did You Make This?Share a comment and rating below! I love hearing what you think!
Recipe is okay, but writer is not very smart. Writer states that pork loins are larger (4-5 pounds or larger) than tenderloins, then proceeds to give a recipe for a 2-3 pound porkloin . Does anyone proofread for her??!! She really needs to be Dinozo’d!
Did you happen to see this note before you left such an unkind review?

Have a great day.
You’re a total ditz!
What’s really going on?
You’re such an inspiration to us all!
It came out perfect! Rice is really hard to nail and i’ve never made it like this before and was a little skeptical. Give it go! This particular rice is very hearty and filling with more “tooth” than normal rice.
Hi Elizabeth! Thanks for the review! I think you may have meant to leave it on a rice recipe but I’m glad you liked the rice!
This was a huge hit in my house! Thanks for the recipe!
I’m so happy to hear that! Thank you for leaving a review!
How is it possible that the internal temperature of the roast rises as it rests with no input of heat? This defies physics.
It’s called carryover cooking. Here is a very nerdy article if you’re interested in learning more: https://blog.thermoworks.com/thermometer/carryover-cooking-what-happens-after-you-cook/
Apparently, you aren’t a cook, or you’d understand resting time… Also, what does physics have to do with it? You’re clearly lacking in that subject as well.
What is the “trivet” you refer to?
Haven’t used my instant pot in a while so maybe I misplaced a part
Could you send me a picture of it?
It’s the wire rack it comes with, a steamer rack. Hope that helps!
The thing raises stuff up over the liquid, with the handles on the side, folds up.
Great flavor and moistness.
Had a one pound roast (2oldies/2 meals) and 18 minutes plus release was perfect, 145 internal after resting.
Used a traeger pork rub and recommended seasonings and perfect for pork roast.
Thanks for your efforts and thanks for not cluttering up your site with garbage pop up’s
Thank you for the kind words!
First time using our Instant pot and this came out perfect! Juicy and delicious! Will definitely make this again!
So happy you liked it! Thank you for taking the time to leave a review!
Absolutely gorgeous and so quick, easy and juicy.
The first joint of meat I have cooked in my instant pot but I’m converted.
No pork loin will ever go into an oven again.
Your comment made my day! Thanks so much for taking the time to leave a review – I’m glad you enjoyed it so much!
i just printed the recipe and i am making it for dinner tonite. I love that you put the details into the instructions so that even a novice can feel comfortable and not second guess anything. for example in #2 you say press the cancel button- some one who is not that proficient with the instant pot might not know to do that step. thanks

Your comment made my day! Thank you so much, I’m thrilled to hear it’s helpful!
Great recipe! Pork loin turned out moist and flavorful. Used a pork rub blend with smoked paprika. Substituted honey for the brown sugar and used beef broth. Added mushrooms and onions to the broth. Definitely will prepare this again.
So happy you liked it!
PattiD; not sure why you thought the recipe she posted was great because you changed the entire recipe. Which is fine but saying it was great is misleading for those of us that want to know if it actually worked out.
Sooo delicious! We drenched the meat, along with mashed potatoes, in the drippings sauce– loved it! Definitely a “print and keep” recipe!
That’s the biggest compliment! So glad you liked it!
