Instant Pot Pork Loin Recipe | Juicy Slices, Rich Gravy

A 2- to 3-pound roast turns tender in about 20 minutes at high pressure, plus a 10-minute natural release and a 145°F finish.

Pork loin can be a little tricky in an Instant Pot. The cut is lean, the cooker runs hot, and a few extra minutes can push it from tender to dry. The good news: once you lock in the timing, this roast becomes one of the easiest dinners you can put on the table.

This version keeps the meat moist with a quick sear, a short pressure cook, and a broth-based gravy made right in the pot. You get neat slices instead of shreds, a savory pan sauce, and leftovers that still taste good the next day.

• It uses pantry basics like broth, garlic, onion, and herbs.
• It works best with a boneless pork loin, not pork tenderloin.
• The gravy comes from the cooking liquid, so nothing goes to waste.
• You can dress it up for guests or pair it with mashed potatoes on a busy night.

Why Pork Loin Works In The Instant Pot

Pork loin is wider and thicker than pork tenderloin. That shape gives you a little room for error in a pressure cooker, as long as you do not cook it like pulled pork. You want slices, not strands. That means a shorter cook time and a short rest before you cut.

The Instant Pot also gives you a built-in flavor boost. Browning the roast right in the insert leaves tasty bits on the bottom, and those bits melt into the broth while the meat cooks. When you whisk the liquid at the end, you get gravy with no extra pan to wash.

Pork Loin Vs. Pork Tenderloin

These cuts are not the same. Pork tenderloin is long, narrow, and much smaller. Pork loin is broader, often sold as a 2- to 4-pound roast, and better suited to this method. If you swap in tenderloin without changing the timing, it can dry out before you even set the table.

What Keeps The Meat Tender

• Sear the outside for color and flavor.
• Set the roast on a trivet so it is not boiling in liquid.
• Use a 10-minute natural release before opening the valve.
• Check the center with a thermometer instead of guessing by color.
• Rest the roast before slicing so the juices stay put.

Ingredients For A Savory Roast

You do not need a long shopping list here. A simple seasoning blend and a flavorful cooking liquid do the job. If your pork loin has a thin fat cap, leave it on. It helps protect the meat while it cooks and adds flavor to the gravy.

• 2 1/2 to 3 pounds boneless pork loin
• 1 tablespoon olive oil
• 1 1/2 teaspoons kosher salt
• 1 teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon dried thyme
• 1/2 teaspoon paprika
• 1 small onion, sliced
• 3 garlic cloves, minced
• 1 cup low-sodium chicken broth
• 1 tablespoon Dijon mustard
• 1 tablespoon Worcestershire sauce
• 1 tablespoon cornstarch mixed with 1 tablespoon cold water

How To Make This Instant Pot Pork Loin Recipe

1. Season The Roast Well

Pat the pork dry with paper towels. Mix the salt, pepper, garlic powder, thyme, and paprika, then rub the blend over the whole roast. Dry meat browns better, and that first layer of seasoning gives the gravy more depth later on.

2. Brown The Outside

Set the Instant Pot to sauté and warm the oil. Sear the roast for about 2 minutes per side until you get a little color. You are not cooking it through here. You are building flavor and giving the finished roast a better look.

3. Build The Cooking Liquid

Move the pork to a plate. Add the onion and cook for 2 to 3 minutes, then stir in the garlic for about 30 seconds. Pour in the broth and scrape the bottom well. Stir in the Dijon and Worcestershire. Set the trivet in the pot, then place the pork on top.

4. Pressure Cook And Let It Rest

Lock the lid, set the valve to sealing, and cook on high pressure. For a 2 1/2- to 3-pound roast, 20 minutes is a strong starting point. When the timer ends, let the pressure drop naturally for 10 minutes. Then release the rest and check the thickest part of the meat.

5. Aim For Temperature, Not Guesswork

You want the center to reach 145°F after a short rest. If your roast is still under that mark by more than a few degrees, lock the lid and cook for 2 to 3 more minutes on high pressure, then do a quick release. Small differences in thickness can change the finish time.

6. Make The Gravy

Move the pork to a cutting board and tent it loosely with foil. Switch the pot back to sauté, whisk in the cornstarch slurry, and simmer for 1 to 2 minutes until the liquid thickens. Slice the pork across the grain and spoon the gravy over the top.

Instant Pot Pork Loin Recipe Timing By Roast Size

Use this table as a starting point. Thickness matters more than weight, so a short, thick roast may need a little more time than a long, narrow one. The USDA safe minimum internal temperature chart sets 145°F plus a 3-minute rest for whole cuts of pork.

Roast Size	High Pressure Time	Release And Finish
1 1/2 pounds	14 minutes	10-minute natural release, then check temp
2 pounds	16 minutes	10-minute natural release, rest after slicing
2 1/2 pounds	18 minutes	10-minute natural release, target 145°F
3 pounds	20 minutes	10-minute natural release, target 145°F
3 1/2 pounds	23 minutes	10-minute natural release, rest 5 to 10 minutes
4 pounds	26 minutes	10-minute natural release, check center well
4 1/2 pounds	29 minutes	10-minute natural release, add time only if needed

Cooking Pork Loin In The Instant Pot Without Dry Meat

The main trap is overcooking. Pork loin is lean, so it does not need the long cook you would give pork shoulder. The USDA fresh pork storage and cooking page also backs up the 145°F finish for roasts. That number is your stop sign.

Another common slip is skipping the natural release. A few minutes of quiet time inside the pot lets the meat finish more gently. Open the valve right away and the fibers tighten up fast. That is when slices start losing juice on the cutting board.

Use The Trivet

Setting the pork on a trivet keeps the bottom from sitting in the broth. You still get moisture in the pot, but the roast acts more like a roast and less like a braise. That gives you cleaner slices with better texture.

Let The Roast Rest

Five to ten minutes makes a big difference. The center temperature climbs a little, and the juices settle back into the meat. Cut too soon and the board ends up wet while the pork tastes dry.

Check Shape, Not Just Weight

If your roast is thick and stubby, start at the higher end of the timing range. If it is long and slim, shave off a minute or two. Even official timing charts, like this Instant Pot roast pork loin recipe, work best when you match them to the shape in front of you.

Flavor Swaps That Still Taste Right

This recipe leans savory, but pork loin takes well to small twists. You do not need a new method. Keep the timing close to the same and swap the seasoning blend or the sauce base.

• Apple And Onion: Add sliced apple to the pot and finish the gravy with a spoonful of apple butter.
• Garlic Herb: Use rosemary and sage with the thyme for a roast that tastes a little more classic.
• Maple Mustard: Stir a tablespoon of maple syrup into the broth for a sweet edge that still feels balanced.
• Smoky Paprika: Add extra paprika and a pinch of cayenne if you want a stronger crust.

Best Sides To Pair With Pork Loin

The gravy pulls the plate together, so sides that catch sauce are a smart move. You can keep the meal simple with one starch and one green vegetable, or fill it out a bit more for a weekend dinner.

Side Dish	Why It Fits	Timing Note
Mashed potatoes	Great with gravy and soft pork slices	Start while the roast rests
Roasted carrots	Sweet edge balances savory sauce	Cook in the oven while the pork cooks
Green beans	Fresh bite cuts the richness	Steam in 8 to 10 minutes
Butter noodles	Easy base for extra gravy	Boil near the end of cooking
Rice pilaf	Soaks up sauce without feeling heavy	Cook on the stove while the roast rests
Wilted spinach	Adds color and a light, earthy note	Done in a skillet in minutes

Storage, Reheating, And Leftover Ideas

Leftover pork loin keeps well if you store it with a little gravy. That extra moisture helps protect the slices in the fridge. Cool the meat, pack it in a covered container, and refrigerate it within 2 hours of cooking. It will hold for about 3 to 4 days.

How To Reheat Without Tough Edges

Warm slices in a skillet with a splash of broth or leftover gravy over low heat. A microwave works too, but cover the pork and use short bursts so the edges do not dry out. Reheating the whole roast in a hot oven tends to push it past its sweet spot.

What To Make With Leftovers

• Hot sandwiches with gravy and soft rolls
• Pork and rice bowls with green beans
• Diced pork folded into fried rice
• Thin slices with eggs and toast the next morning

A Pork Loin Dinner That Feels Planned

This roast earns a spot in the weeknight rotation because it tastes like more work than it is. Once you know your timing, the whole thing feels steady and repeatable. Sear, pressure cook, rest, slice, and pour on the gravy.

If you have struggled with dry pork in the past, this method fixes the usual trouble spots. Use pork loin, not tenderloin. Pull the roast once it reaches 145°F. Give it a few quiet minutes before slicing. That is the difference between meat that is fine and meat people ask for again.
