The pressure cooking function of an instant pot drastically reduces the time needed for a pork roast. If you want to know how to cook pork roast in instant pot without spending hours in the kitchen, you have come to the right place. This guide will walk you through every step, from picking the right cut to serving a tender, juicy meal.
Forget about dry, overcooked pork. The Instant Pot locks in moisture and flavor, giving you a roast that shreds or slices beautifully. You do not need any special skills—just a few ingredients and your pressure cooker.
Why Use An Instant Pot For Pork Roast
Traditional oven roasting takes hours. The Instant Pot cuts that time by more than half. You get the same deep flavor and tender texture, but in a fraction of the time.
Pressure cooking breaks down connective tissues quickly. This means tougher cuts like pork shoulder become fork-tender in about an hour. Plus, you can sear the meat right in the pot, saving dishes and adding flavor.
Another benefit is consistency. The Instant Pot regulates temperature and pressure perfectly. You will not have to worry about hot spots or uneven cooking.
Choosing The Right Cut Of Pork
Not all pork roasts are the same. For best results in the Instant Pot, pick a cut with some fat and connective tissue. Lean cuts can dry out under pressure.
Best Cuts For Instant Pot Pork Roast
- Pork shoulder (also called Boston butt or picnic roast)
- Pork loin roast (leaner, but works with shorter cook times)
- Pork sirloin roast
- Boneless country-style ribs (great for shredding)
Pork shoulder is the most forgiving. It stays moist even if you cook it a bit longer. Pork loin is leaner and needs careful timing to avoid dryness.
What To Look For When Buying
- Look for even thickness so it cooks uniformly
- Check for a good fat cap on top
- Avoid roasts with large bones unless you adjust cook time
- Fresh pork should be pink with white fat, not gray or brown
Essential Ingredients And Tools
You do not need a long list of ingredients. Simple seasonings work best. Here is what you will need.
Basic Ingredients

- Salt and black pepper
- Garlic powder, onion powder, paprika (optional)
Optional Flavor Boosters
- Fresh garlic cloves (3-4, smashed)
- Fresh rosemary or thyme sprigs
- 1 tablespoon Worcestershire sauce
- 1 tablespoon apple cider vinegar
- 1 chopped onion or shallot
Tools Needed

- Cutting board and sharp knife
How To Cook Pork Roast In Instant Pot: Step-By-Step
Follow these steps exactly for a perfect roast every time. The process is simple, but each step matters.
Step 1: Prepare The Pork Roast
Take the pork out of the fridge 20 to 30 minutes before cooking. This helps it cook more evenly. Pat it dry with paper towels. Dry meat sears better.
Trim excess fat if needed, but leave a thin layer for moisture. Season generously with salt, pepper, and any other spices you like. Rub the seasoning into all sides.
Step 2: Sear The Roast
Turn your Instant Pot to the “Sauté” function on high. Add the oil and let it heat until shimmering. Carefully place the pork roast in the pot. Do not crowd it—sear in batches if needed.
Cook for 3 to 4 minutes per side until deeply browned. Use tongs to flip. Searing creates a crust that locks in flavor. Do not skip this step.
Once seared, remove the roast and set it on a plate. If you want, add chopped onions or garlic to the pot and sauté for 1 minute to build more flavor.
Step 3: Deglaze The Pot
Pour in 1 cup of broth or water. Use a wooden spoon to scrape up any browned bits from the bottom. These bits are packed with flavor. If you skip deglazing, you might get a “burn” warning later.
Make sure the liquid covers the bottom of the pot completely. This is essential for pressure cooking.
Step 4: Pressure Cook The Roast
Return the pork roast to the pot. Add any aromatics like rosemary or garlic around the meat. Do not submerge the roast fully—just let the liquid come partway up the sides.
Close the lid and set the valve to “Sealing.” Select “Manual” or “Pressure Cook” on high pressure. Set the time based on your cut:
- Pork shoulder (2-3 lbs): 60 to 70 minutes
- Pork loin (2-3 lbs): 25 to 30 minutes
- Pork sirloin (2-3 lbs): 30 to 40 minutes
- Country-style ribs: 20 to 25 minutes
For larger roasts (4-5 lbs), add 10 to 15 minutes. Always check with a meat thermometer—internal temp should be 145°F for safety, but 190°F to 205°F for shredding.
Step 5: Natural Pressure Release
When the timer beeps, let the pressure release naturally for at least 15 minutes. This is crucial for tender meat. Quick release can make the pork tough.
After 15 minutes, you can carefully turn the valve to “Venting” to release any remaining steam. Open the lid away from your face.
Step 6: Rest And Serve
Use tongs to transfer the roast to a cutting board. Let it rest for 5 to 10 minutes. This allows juices to redistribute. Slice against the grain for tenderness, or shred with two forks.
If you want a thicker sauce, turn the Instant Pot back to “Sauté.” Simmer the liquid for 5 to 10 minutes until it reduces. You can also add a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) to thicken.
Tips For The Best Instant Pot Pork Roast
Small adjustments make a big difference. Here are some pro tips to elevate your roast.
Do Not Overcrowd The Pot
The Instant Pot needs space to build pressure. If your roast is too large, cut it in half or use a bigger pot. A 6-quart pot works well for roasts up to 4 pounds.
Use Enough Liquid
Always add at least 1 cup of liquid. Broth adds flavor, but water works in a pinch. Do not use thick sauces like tomato paste without thinning them first.
Let It Rest
Resting is not optional. Cutting into the roast too early lets juices run out, leaving dry meat. Wait the full 10 minutes.
Adjust For Altitude
If you live above 3,000 feet, increase cooking time by 5 to 10 percent. Check your Instant Pot manual for specific guidelines.
Flavor Variations To Try
Once you master the basic method, experiment with different flavors. Here are three easy variations.
Garlic And Herb Pork Roast
Add 4 smashed garlic cloves and 2 sprigs of rosemary to the pot. Season the roast with dried thyme and oregano. Use chicken broth as the liquid.
BBQ Pulled Pork
After cooking, shred the pork and toss with 1 cup of your favorite BBQ sauce. Return to the pot and sauté for 5 minutes to meld flavors. Serve on buns with coleslaw.
Mexican-Style Pork Roast
Season the roast with cumin, chili powder, and oregano. Add 1 cup of salsa verde instead of broth. Shred and use for tacos or burritos.
Common Mistakes And How To Avoid Them
Even experienced cooks make errors. Here are the most common ones and how to fix them.
Mistake: Dry Pork
Cause: Overcooking or using a lean cut without enough liquid. Fix: Use a fattier cut like shoulder, and always add enough broth. Check internal temp early.
Mistake: Burn Warning
Cause: Not deglazing the pot after searing. Fix: Scrape up all browned bits before adding liquid. Make sure the bottom is covered.
Mistake: Tough Meat
Cause: Not cooking long enough for tough cuts. Fix: Pork shoulder needs at least 60 minutes. Use natural release for extra tenderness.
Mistake: Bland Flavor
Cause: Not enough seasoning or skipping the sear. Fix: Season generously and sear until deep brown. Add aromatics to the cooking liquid.
How To Store And Reheat Leftovers
Leftover pork roast is versatile. Store it properly to maintain texture.
Refrigerating
Place cooled pork in an airtight container. Add a little cooking liquid to keep it moist. It will last 3 to 4 days in the fridge.
Freezing
Shred or slice the pork. Wrap tightly in plastic wrap, then foil, or use a freezer bag. Remove as much air as possible. Freeze for up to 3 months.
Reheating
For best results, reheat in the Instant Pot on “Sauté” with a splash of broth. You can also microwave in 30-second bursts, covered. Add a little liquid to prevent drying.
Frequently Asked Questions
Can I Cook A Frozen Pork Roast In The Instant Pot?
Yes, but you need to add 50% more cooking time. For a 3-pound frozen roast, cook for 90 minutes. Make sure the internal temp reaches 145°F. Do not sear a frozen roast—it will not brown well.
How Do I Know When The Pork Roast Is Done?
Use a meat thermometer. For safety, pork should reach 145°F. For shredding, aim for 190°F to 205°F. The meat should pull apart easily with a fork.
Can I Use Water Instead Of Broth?
Yes, water works fine. But broth adds more flavor. If using water, increase your seasonings slightly to compensate.
Why Did My Pork Roast Come Out Dry?
Most likely you used a lean cut or cooked it too long. Pork loin is especially prone to dryness. Try a fattier cut like shoulder next time, and use natural pressure release.
Can I Add Vegetables To The Pot With The Pork?
Yes, but add them later in the cooking process. Root vegetables like carrots and potatoes need about 15 to 20 minutes under pressure. Add them after the pork has cooked for half the time, then continue cooking.
