In this guide, I’ll share my tips for exactly how long to cook pork loin in the Instant Pot for perfect doneness.

Why Cook Pork Loin in an Instant Pot?

The Instant Pot is ideal for pork loin because

  • Cooks the meat quickly thanks to pressure cooking
  • Keeps the pork tender and moist
  • Infuses flavor into the meat
  • Minimal hands-on time needed
  • Convenient – no need to monitor the oven

With the right timing, you’ll enjoy stellar results every time.

Average Instant Pot Pork Loin Cook Times

As a general rule of thumb, use these Instant Pot pork loin cook times as a starting point:

  • 1-2 lb pork loin: 25-35 minutes
  • 3-4 lb pork loin: 35-45 minutes
  • 5-6 lb pork loin: 45-60 minutes

The shape, thickness, and bone-in vs boneless all impact timing. Use a meat thermometer for best accuracy.

Instant Pot Temperature for Pork Loin

Cook the pork loin at high pressure in the Instant Pot. For food safety, pork needs to reach an internal temperature of at least 145°F.

  • For medium doneness, target an internal temp of 145°F
  • For medium well, aim for 150-155°F
  • For well done pork, cook to 160°F

Always use a meat thermometer to check doneness instead of relying solely on time.

Calculating Exact Instant Pot Pork Loin Time

While the estimates above provide a starting point, the precise Instant Pot pork loin cook time depends on:

1. Thickness – A 2-inch thick roast needs more time than a 1-inch thick chop.

2. Weight – Heavier roasts require longer cook times.

3. Shape – Uniform roasts cook evenly, oddly shaped pieces may need more time.

4. Bone-in or Boneless – Bone-in pork loin takes longer.

5. Desired Doneness – The final internal temp impacts total time.

Let’s look at how to determine the exact Instant Pot cook time based on these factors.

Checking Doneness of Instant Pot Pork Loin

To test if your pork loin is ready, use these foolproof methods:

  • Meat thermometer is most accurate – insert into thickest area and check temperature

  • Slice pork loin open – Meat should no longer be pink in center

  • Test texture – Pork should feel firm, not squishy

Once the innermost portion of the pork loin reaches 145°F, it is safely cooked through.

To achieve tender, juicy pork loin, avoid these common pitfalls:

  • Not using natural pressure release – Causes meat to toughen

  • Quick release right away – Leads to drier pork

  • No resting time after pressure cooking – Results in juices spilling out

  • Skipping meat thermometer – Makes it hard to confirm safe doneness

By following the steps above and using a meat thermometer, you’ll get perfect results every time.

How Long to Cook a Pork Loin in the Instant Pot

The cook time will depend on the size and thickness of your pork loin. Here is a general guide:

  • For a 2-pound pork loin, cook it under high pressure for 14 minutes and then let the pressure naturally drop for 20 minutes.
  • 2. Pressure cook a 5-pound pork loin for 16 minutes on high pressure, then let the pressure drop naturally for 20 minutes.
  • For a 3-pound pork loin, cook it under high pressure for 18 minutes and then let the pressure naturally release for 20 minutes.

The best way to tell if the pork is cooked through is to use an instant read thermometer to test the temperature of the center of the meat. The USDA recommends cooking whole cuts of pork to 145° F, and they note that pork may still be a little pink in the center at this temperature.

If the pork isn’t quite done after pressure cooking, put the lid back on the pot and turn on the sauté function. Let the sauce come to a simmer, then turn off sauté and put the lid back on the pot for about 5 minutes. Do this again and again until the pork reaches 145° F.
