Ingredients for boneless pork loin instant pot
Fourteen ingredients, one pot, restaurant-quality pork in 30 minutes—no oven needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin 🥓 | 1 ½ lb | Center-cut, 1.5-inch thick slices |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, stems removed |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked |
| Apple Cider Vinegar 🍎 | 1 tbsp | For marinade brightness |
| Brown Sugar 🍬 | 1 tbsp | Light or dark variety |
| Low-Sodium Chicken Broth 💧 | ½ cup | For Instant Pot liquid |
| Honey 🍯 | 1 tbsp | For glaze finish |
| Cornstarch 🌾 | 1 tbsp | For glaze thickening |
| Fresh Parsley 🌿 | ⅛ cup | Chopped, for garnish |
The pork loin makes all the difference here. Center-cut is key—it stays tender without turning mushy. I always pick up mine from Whole Foods or Costco because they carry high-quality cuts with good marbling. Look for pieces that are about 1.5 inches thick—thinner slices can dry out, even in the Instant Pot. If you're using frozen pork, thaw it completely in the fridge overnight. Fresh herbs are a must for this recipe, so hit up your local farmers market for rosemary and thyme—they'll have more flavor than anything from the grocery store's herb section.
No fresh rosemary? Dried works at one-third the amount, but honestly, it's not the same. Short on apple cider vinegar? Lemon juice does the trick in a pinch. Want to skip the honey glaze? A little maple syrup gives the same sweetness without altering the flavor profile. The chicken broth is just there to create steam—you can use water in a bind, but the broth adds depth. For the glaze, if you're not using cornstarch, arrowroot powder works just as well. And if you've got leftover pork, slice it thin for sandwiches or tacos—it reheats beautifully.
This pork keeps for 4 days in the fridge, but honestly, it disappears faster than that. For leftovers, store in an airtight container with a paper towel to absorb any moisture. Freeze for up to 3 months if you're planning ahead. The glaze sets as it cools, so if you're serving it right away, reheat it gently in the microwave with a splash of water. I always make a double batch—one for dinner and one for lunch the next day. The Instant Pot makes this so easy that you'll want to cook it twice a week.

Step-by-step instructions for pressure-cooked pork loin
Here's how to transform tender pork loin into melt-in-your-mouth perfection using your Instant Pot.
Sear the Pork Loin for Maximum Flavor
Begin by patting the boneless pork loin completely dry with paper towels—this ensures a proper sear. Heat the Instant Pot on the "Sauté" function until the pot is hot, then add the 2 tablespoons olive oil. Once shimmering, carefully place the pork loin in the pot and sear for 2-3 minutes per side until golden brown. You'll see the edges develop a beautiful crust, which locks in juices and builds deep flavor.
While the pork sears, combine the 4 cloves minced garlic, 0.25 cup chopped rosemary, 0.25 cup thyme leaves, 1.5 teaspoons kosher salt, and 1 teaspoon black pepper in a small bowl. Once the pork is browned, spoon this herb mixture over the top, pressing gently to help it adhere. The aromatic herbs will infuse into the meat during cooking, creating layers of flavor.
Pressure Cook to Juicy Perfection
After searing, pour in the 0.5 cup low-sodium chicken broth and 1 tablespoon apple cider vinegar. The acidity from the vinegar helps tenderize the meat while adding brightness to the final dish. Place the trivet in the Instant Pot (if using one) and position the pork loin on top, making sure it's elevated above the liquid to prevent steaming instead of pressure cooking.
Secure the lid, set the valve to "Sealing," and cook on "High Pressure" for 18 minutes. This time ensures the pork reaches a perfect internal temperature of 145°F without overcooking. The pressure cooking method creates an environment where the meat becomes fork-tender while retaining all its natural juices. Don't be tempted to check the doneness early—the pressure build-up is crucial for even cooking.
Prepare the Honey-Glaze While Cooking
While the pork pressure cooks, prepare the glaze by combining the 1 tablespoon honey, 1 tablespoon brown sugar, and 1 tablespoon cornstarch in a small bowl. This mixture will create a beautiful caramelized finish that adds sweetness and sheen to the pork. Once the cooking cycle completes, let the pressure release naturally for 10 minutes before quick-releasing any remaining pressure.
After the pressure has fully released, carefully remove the pork loin from the pot and transfer it to a cutting board. Tent loosely with aluminum foil to keep it warm while you prepare the glaze. The natural juices released during cooking will create a flavorful sauce in the bottom of your Instant Pot—save about 0.25 cup of this liquid for the glaze.
Glaze and Rest for Maximum Juiciness
Return the Instant Pot to the "Sauté" function and add the reserved pork juices. Whisk in the honey-sugar-cornstarch mixture until smooth and slightly thickened, about 1-2 minutes. The cornstarch will help create a glossy, sticky glaze that clings beautifully to the pork. Pour this mixture over the pork loin, making sure to coat all sides evenly. Let it sit for 2-3 minutes while you prepare the garnish.
Slice the pork loin into 0.5-inch thick medallions and arrange on a serving platter. Spoon any remaining glaze over the top and garnish with the 0.125 cup chopped fresh parsley. The parsley adds a fresh contrast to the rich, caramelized pork. Let the pork rest for 5 minutes before serving to allow the juices to redistribute throughout each slice. You'll notice the meat is incredibly tender and holds together beautifully, with that perfect balance of sweet, herby, and savory flavors.
Pro Tips For Making Boneless Pork Loin Instant Pot
- SEAR FIRST, THEN SAUCE: The Instant Pot’s high-pressure magic works best when the pork starts with a crust. Heat your olive oil until it shimmers, then sear the pork on all sides for 2-3 minutes—don’t rush, or you’ll end up with bland, steamed meat. After searing, add your garlic, rosemary, and thyme directly to the pot (no need to pre-chop them finely), then pour in any broth or wine. The aromatics stick better this way, and the crust locks in flavor.
- TRIM THE FAT, NOT THE FLAVOR: Boneless pork loin can be lean, and that’s fine—but if your cut has visible fat marbling, trim it thinly with kitchen shears, leaving just enough to keep the meat juicy. I used to over-trim, and the result was dry pork. (Yes, even with the Instant Pot’s moisture help.) Leave the herbs whole or in small sprigs—they’ll infuse better than if you minced them into oblivion.
- DON’T SKIP THE NATURAL RELEASE: After cooking, resist the urge to quick-release the pressure—let the pork rest for at least 10 minutes. I learned this the hard way when I opened the lid too soon and watched the juices rush out. The meat needs that time to reabsorb everything, or you’ll end up with a slice that falls apart like overcooked chicken. (Pro move: Tent loosely with foil while resting.)
- UPGRADE WITH A SPLASH OF WINE: You don’t need a fancy bottle—just ¼ cup of whatever you have (even cooking wine works). Deglaze the pot with it after searing, scraping up the browned bits that hold all the flavor. The alcohol burns off during pressure cooking, but it carries the garlic and herbs’ oils right into the meat. I was skeptical until I tried it—now it’s non-negotiable.
Common mistakes when making this dish
Overcooking Time
One of the biggest mistakes is leaving the pork in the Instant Pot too long—even just 5 extra minutes can turn tender meat into something dry and chewy. The 18-minute high-pressure cook is perfect for 1.5-inch thick pork loin slices, and that's non-negotiable.
I've ruined perfectly good pork by overcooking it, so always set a timer and resist the urge to peek at the meat before the cycle ends. 🌡️
Skipping the Sear
Skipping the sear step is a huge flavor mistake. That golden crust isn't just for looks—it locks in juices and creates the Maillard reaction that builds deep, meaty flavor. I've tested this recipe both ways, and the seared version tastes like it came from a restaurant.
Use 2 tbsp olive oil and let the pork brown for 2-3 minutes per side—don't rush this step.
Wrong Liquid Ratio
Adding too much liquid to your Instant Pot will steam the pork instead of pressure cooking it, resulting in bland, waterlogged meat. The 0.5 cup chicken broth is perfect for creating steam without drowning the pork.
If you're tempted to add more, remember: the pork releases its own juices during cooking. Too much liquid = soggy pork. 💧
Quick-Release Only
Quick-releasing the pressure immediately after cooking can cause the pork to become tough. Always let the Instant Pot release pressure naturally for 10 minutes first, then do a quick release.
This gradual release helps the meat fibers relax and stay tender. I've learned this the hard way—tough pork is no fun!
Ignoring Rest Time
Skipping the 5-minute rest before slicing is a cardinal sin. This resting period allows the juices to redistribute throughout the meat, ensuring each slice stays moist.
I've seen people slice pork immediately after cooking, and it's always disappointing—dry on the outside, juicy only in the center. Patience pays off here! ⏰
Improper Slicing
Cutting against the grain is essential for tender slices, but many people don't realize pork loin has a distinct grain pattern. Look for the muscle fibers and slice perpendicular to them for 0.5-inch thick medallions.
I use a sharp chef's knife and rotate the cutting board as needed. Thick slices against the grain can be tough, while proper slicing makes each bite melt-in-your-mouth perfect.

Frequently asked questions
Can I use frozen pork loin in this Instant Pot recipe?
No, frozen pork loin isn't suitable for this method. Always use fully thawed meat to ensure even cooking and proper doneness. Thaw overnight in the fridge for best results—never at room temperature. The Instant Pot works best with fresh meat that's properly prepped and ready to cook.
What's the best way to check if the pork is fully cooked?
Use a meat thermometer to verify the internal temperature reaches 145°F at the thickest part. The 18-minute cook time is calibrated for perfect doneness, but checking with a thermometer gives you absolute confidence. No more guessing—just science!
Can I make this recipe without a trivet?
Yes, but with one important adjustment. If you don't have a trivet, place the pork loin directly in the Instant Pot with the 0.5 cup broth and 1 tbsp vinegar. The key is keeping the meat elevated enough to pressure cook rather than steam. Just add a little extra liquid (about 0.25 cup total) to ensure proper pressure build-up.
How do I adjust this recipe for a larger crowd?
For every additional 1 lb of pork loin, increase the cook time by 2-3 minutes and add 0.25 cup extra broth. Keep the same thickness (1.5 inches) for even cooking. The Instant Pot's capacity varies by model, so check your manual first—most can handle up to 3 lbs of pork safely in one batch.
What are the best side dishes for this pork?
This juicy pork pairs beautifully with roasted potatoes, garlic green beans, or a fresh herbed salad. For a hearty meal, try mashed sweet potatoes or apple sauce—the sweetness complements the honey glaze perfectly. The Instant Pot makes it easy to cook sides simultaneously using the "Sauté" function.
