Why You’ll Like This Instant Pot Pork Loin Roast

Pork loin is fairly lean, so the main trick is avoiding overcooking it.

Searing the roast first gives the outside a deeper flavor, while pressure cooking with broth keeps the cooking environment moist. The potatoes and carrots make the meal more filling without needing a separate side dish.

A few things make this recipe especially useful:

• Everything cooks in one Instant Pot
• The pork gets browned before pressure cooking
• Potatoes and carrots cook in the same pot
• The cooking liquid becomes a simple sauce
• You can adjust the seasoning to your taste
• It works well for leftovers

Ingredients

For the pork

• 2 to 2½ pounds boneless pork loin roast
• 1 tablespoon olive oil
• 1½ teaspoons kosher salt
• 1 teaspoon paprika
• 1 teaspoon garlic powder
• ½ teaspoon black pepper
• ½ teaspoon dried thyme
• ½ teaspoon dried rosemary

For the vegetables

• 1 pound baby potatoes, halved if large
• 3 large carrots, cut into thick pieces
• 1 medium yellow onion, cut into wedges
• 4 garlic cloves, minced

For the cooking liquid

• 1½ cups chicken or vegetable broth
• 1 tablespoon Worcestershire sauce
• 1 tablespoon Dijon mustard

For a thicker finishing sauce:

• 1 tablespoon cornstarch
• 2 tablespoons cold water

How to Make Instant Pot Pork Loin Roast with Potatoes and Carrots

1. Season the pork

Pat the pork loin dry with paper towels.

Mix the salt, paprika, garlic powder, black pepper, thyme, and rosemary in a small bowl. Rub the seasoning evenly over the pork.

Drying the surface first helps the roast brown instead of immediately steaming when it hits the hot pot.

2. Sear the pork loin

Set the Instant Pot to Sauté and add the olive oil.

When the oil is hot, place the pork loin in the pot. Brown it on several sides, turning it with tongs as needed.

You do not need to cook the center at this stage. The goal is simply to develop color on the outside.

Transfer the pork to a plate.

3. Deglaze the pot

Turn off Sauté and pour in the broth.

Use a wooden or silicone spoon to scrape the browned bits from the bottom.

This step matters because those browned pieces add flavor to the cooking liquid, and removing them helps prevent a burn warning.

Stir in the Worcestershire sauce and Dijon mustard.

4. Add the vegetables

Place the onion and garlic into the liquid.

Add the potatoes and carrots around the pork, then place the seasoned pork loin back into the pot.

Try to keep the vegetables in reasonably large pieces. Very small potatoes or thin carrot slices can become overly soft during pressure cooking.

5. Pressure cook

Lock the Instant Pot lid and set the valve to Sealing.

Cook on High Pressure according to the size and thickness of your roast, using the recipe timing as a starting point.

For a 2 to 2½-pound pork loin, begin with about 18 minutes on High Pressure, followed by a 10-minute natural release.

After 10 minutes, carefully release the remaining pressure.

The most important check is the pork’s internal temperature, not the clock alone. Insert an instant-read thermometer into the thickest part of the roast.

For food safety, pork should reach at least 145°F (63°C) and rest for at least 3 minutes.

6. Rest the pork

Transfer the pork to a cutting board and let it rest for several minutes before slicing.

Do not immediately cut the roast into thin slices after opening the Instant Pot. Resting gives the juices time to redistribute.

7. Finish the sauce

If you want a thicker sauce, switch the Instant Pot back to Sauté.

Mix the cornstarch with cold water until smooth. Stir the mixture gradually into the hot cooking liquid.

Let it simmer briefly until the sauce reaches the consistency you prefer.

Taste before adding more salt because the broth, Worcestershire sauce, and seasoning already contribute salt.

How to Get Tender Pork Loin in the Instant Pot

The biggest mistake with pork loin is treating it like a tough pork shoulder.

They are different cuts.

Pork loin is relatively lean and can become dry if it is cooked far beyond the temperature needed for safe doneness.

Use these habits for better results:

• Start with a similar-sized roast so it cooks evenly.
• Pat the pork dry before seasoning and searing.
• Do not skip the browning step if you want deeper flavor.
• Use enough liquid for pressure cooking.
• Avoid adding excessive cooking time just because the pork looks firm.
• Check the thickest part with a thermometer.
• Let the roast rest before slicing.

If your pork is already dry, adding more pressure-cooking time usually will not fix the problem.

Instant Pot Pork Roast with Potatoes and Carrots: Timing Tips

The size of the roast makes a difference.

A thick 2½-pound roast does not cook exactly like a thin 2-pound roast, even if the weight is similar.

For that reason, use pressure-cooking time as a starting point and verify the final temperature with a thermometer.

The vegetables also need attention.

Baby potatoes or large potato chunks hold their shape better than small diced potatoes. Carrots should also be cut into fairly thick pieces.

If you prefer very firm vegetables, cook the pork first and pressure cook the vegetables separately for a short time in the remaining liquid.

Can You Make Instant Pot Pork Loin Roast Boneless?

Yes. A boneless pork loin roast works very well in this recipe.

Because boneless pork loin can vary in thickness, avoid choosing cooking time based only on weight.

A long, thin roast may cook differently from a shorter, thicker one.

The thermometer is the best way to check whether the center has reached the appropriate temperature.

What About Instant Pot Pork Loin with Carrots and Onions?

Carrots and onions are especially good with pork because they add sweetness and savory flavor to the cooking liquid.

For Instant Pot pork loin with carrots and onions, cut the carrots into thick pieces and the onions into wedges.

The onion will become very soft and partly blend into the sauce. If you prefer more visible onion pieces, add some of them later instead of pressure cooking all of them from the beginning.

Instant Pot Pork Loin Chunks

You can also adapt this style of recipe for Instant Pot pork loin chunks.

Cut the pork into larger pieces rather than tiny cubes and season them before browning.

Smaller pieces cook faster and can become dry more easily, so avoid treating pork loin chunks exactly like a large roast.

This version is useful when you want the pork mixed directly with the vegetables and sauce instead of slicing a whole roast.

Instant Pot Pork Loin Pulled Pork: Is It the Same?

Not really.

Pork loin is lean, while traditional pulled pork is usually made from a fattier cut such as pork shoulder.

You can pressure cook pork loin until it becomes shreddable, but it is more likely to become dry than pork shoulder.

If your goal is juicy, shreddable Instant Pot pork loin pulled pork, use plenty of flavorful liquid and avoid expecting the same texture you get from a well-marbled shoulder.

Can Pork Tenderloin and Potatoes Cook Together?

Yes, but pork tenderloin and pork loin roast are not the same cut.

Tenderloin is smaller and cooks much faster.

If you cook a whole pork tenderloin for the same amount of time as a large pork loin roast, it can easily become overcooked.

For pork tenderloin and potatoes at the same time, use appropriately sized potato pieces and choose the cooking time around the tenderloin rather than treating it like a large roast.

Serving Ideas

This meal is already fairly complete, but a few simple additions work well.

Serve the sliced pork with:

• The cooked potatoes and carrots
• Extra pan sauce
• Steamed green beans
• A simple green salad
• Roasted broccoli
• Crusty bread

A little fresh parsley or chopped chives over the finished plate also adds color and freshness.

How to Store Leftovers

Let leftover pork cool and refrigerate it in a covered container.

For better texture, slice only the amount you plan to eat rather than slicing the entire roast at once.

The leftover pork works well in sandwiches, wraps, salads, rice bowls, or reheated with some of the cooking sauce.

When reheating, use gentle heat and avoid cooking it for much longer than necessary.
