This Instant Pot Pork Roast Recipe is a simple way to cook a pork roast that is flavorful and tender in a fraction of the time.
The Instant Pot is an incredible tool in the kitchen for making dishes that usually take a long time. In the pressure cooker, you can drastically cut down the cooking time for dishes like this tender pork roast.
The best thing about this pork roast is that it goes with just about any side dish you want to serve, so you don’t have to put a lot of thought into what to make for dinner.
Which Cut of Pork to Use
There are a few different cuts of pork that make a good pork roast. You can use pork shoulder (also called pork butt), pork leg, or loin.
I cook a LOT of pork shoulder in the instant pot, for things like carnitas or pulled pork – great for pulled pork gnocchi, that benefit from slow cooking. It turns out so tender and falls apart easily to shred it.
When I’m making a pork roast that I want to be able to slice and serve with a side dish, I typically use pork leg. I mostly find pork leg weighing around 2-4 lbs, which fits nicely in the 6 – 8 qt Instant Pot and feeds around 4-8 people.
Pork leg turns out in one large pieces of meat, while pork shoulder tends to be more marbled. That’s what makes it so great for pulled pork.
The pork leg roast pictured above is a 3 pound roast that is about 5 inches thick. a 3 lb roast will cook in 90 minutes in the Instant Pot.
Pork loin is the leanest cut of meat and doesn’t have much fat. It’s also usually sold in smaller roasts that are thinner. Thus, a pork loin will cook a lot faster in the Instant Pot. Overcooking can quickly lead to dry pork. That’s why I mostly avoid this cut.
Pork chops are a quick and easy weeknight meal.
Why Use An Instant Pot?
The Instant Pot is one of the most useful kitchen appliances you can buy, because it drastically cuts down on the cooking time for developing flavors in soups and stews, getting tough cuts of meat tender, and even baking a cheesecake. And there are many accessories that will help you get more out of your Instant Pot.
Preparing the Pork Roast
Pork roasts generally come tied up or covered with a string netting. This is to keep the meat together in one piece while it cooks. I usually remove all of that, so I can remove the skin and fat cap. Then if the meat isn’t in one solid piece, I’ll tie it a couple of times with string to keep it together.
I find that pork shoulder is the one that needs to be tied up. Pork leg generally stays in one piece.
In most cases, the roast will come with a large fat cap and the skin left on. I like to remove those when cooking in the Instant Pot. If you were to cook this roast in the oven, it would have time for the fat to render and the skin to crisp up, but that doesn’t happen in the Instant Pot.
So grab a large knife and carefully cut the skin and fat away from the meat, trying not to cut into the meat. It’s better to leave on a little extra fat, which will help with moistness and flavor.
Adding Salt & Pepper
For a typical pork roast, the only flavoring that it really needs is salt and pepper. I use a mixture of coarsely ground kosher salt and black pepper. It takes about 1 1/2 tsp of each for a total of 3 teaspoons to coat the entire pork well. Be sure to use it all because it does need it.
Pat the pork dry before putting on the seasoning. Get it into all the little nooks. Then let is sit for about 5 minutes.
How to Make a Pork Roast in the Instant Pot
1. Sear the Pork
Start by searing the pork on all sides. This will give the pork a nice browned and flavorful crust.
I sear the pork directly in the Instant Pot on saute mode in olive oil. Once it’s browned, about 3 minutes per side, I remove it from the pot and turn off the machine.
Be aware that the dry rub will begin to burn on the bottom of the Instant Pot if you take too long with this step. It should just take about 6 minutes. If the rub is starting to burn on the bottom, remove the roast and add more oil to the pot.
As soon as the pork is mostly browned, turn off saute mode. It will remain hot enough to finish the sear.
Remove the roast once it’s browned.
2. Cooking the Pork Roast
There will be some browned bits on the bottom of the pot from searing the pork. You need to get that up before cooking. Add the water to the pot and use a whisk to scrape the bits up.
This adds great flavor to the broth, which will be used later to make the gravy.
Close the Instant Pot and set it to pressure cook for 45 minutes. This is perfect for a 3 lb roast.
The length of time you need to cook the pork for will vary depending on the size of your roast. It is recommended that you cook a boneless pork roast for 15 minutes per pound in the Instant Pot. Cooking it this long will lead to a sliceable roast, not a fork tender roast.
After the time is up, allow the pressure to release naturally for 10 minutes, then manually release the rest of the pressure.
2. Slice It Up and Serve It
Take the pork out of the Instant Pot and let it rest a few minutes. Then slice it into pieces, or serve it on a platter to be sliced at the table.
I like to make gravy from the broth left over in the Instant Pot. You can do that right in the pot – no need to use a separate pan. It’s incredibly flavorful and makes a really great gravy.
First, check the level of fat in the broth. If there’s a large layer of fat on the top of the broth, strain it off first. You don’t want greasy gravy! Turn the saute mode back on. Once the liquid is boiling, add a slurry of cornstarch (1 tsp cornstarch mixed with 1 tsp cold water). Whisk it until it’s thickened.
What to Serve With Pork Roast
There are so many great side dishes you can serve with pork roast. Try these Instant Pot potatoes and carrots, baked potatoes, or mashed potatoes. We also like to serve it with Corn on the Cob or Baked Beans.
