Ingredients for boneless pork loin roast instant pot
Six simple ingredients transform basic pork into melt-in-your-mouth perfection with zero oven fuss.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin Roast 🍖 | 2 lb | Center-cut for even cooking |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For crust development |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Cracked peppercorns preferred |
| Garlic Cloves 🧄 | 6 cloves | Smashed for intense flavor |
| Fresh Rosemary 🌿 | ½ tsp | Chopped, stems removed |
| Fresh Thyme Leaves 🌿 | ½ tsp | From 2 sprigs |
| Apple Cider Vinegar 🍎 | 1 tbsp | For tenderizing |
| Low-Sodium Chicken Broth 💧 | ½ cup | For moisture |
| Honey 🍯 | 1 tbsp | For caramelization |
| Cornstarch 🌾 | 1 tbsp | For glossy finish |
| Water 💧 | 1 cup | For pressure cooking |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The pork cut matters most here—center-cut boneless loin stays juicy while the outer edges develop that golden crust. Costco or Whole Foods carry the best quality, but any well-marbled loin works. Look for even thickness (about 1.5 inches) so it cooks uniformly. Fresh herbs? Trader Joe's sells pre-chopped rosemary and thyme that saves time, but whole sprigs are better if you've got them. The honey should be raw and unfiltered—Manuka or local varieties add extra depth, but any good-quality honey works.
No fresh rosemary? Dried at half the amount gets you close, but the flavor won't be as vibrant. Short on time? Garlic powder plus a pinch of onion powder replaces the smashed cloves. The apple cider vinegar is non-negotiable—it tenderizes the meat while adding subtle tang. For a richer finish, swap the chicken broth for beef broth or white wine. Cornstarch is optional but creates that restaurant-worthy glossy crust. Skip it if you're in a pinch, but trust me on the honey—it's worth the extra minute to whisk it with the cornstarch before adding.
This roast reheats beautifully—just add a splash of broth and 5 minutes in the Instant Pot on high. Keeps 4-5 days in the fridge, freezes for 3 months wrapped tightly. I always make a double batch for leftovers—sliced thin over greens or in sandwiches, it's pure magic. For extra flavor, brush the cooked roast with more honey and broil for 2 minutes. The crust gets even better the next day, so plan ahead.

Step-by-step instructions for pressure-cooked pork loin roast
Here's how to transform a simple pork loin into melt-in-your-mouth perfection using your Instant Pot.
Prep the Pork for Maximum Tenderness
Start by patting the 2 lb boneless pork loin roast completely dry with paper towels. This step is crucial—moisture on the surface prevents that beautiful crust from forming. I like to press down firmly with my hands to remove any lingering dampness, especially in the crevices.
Next, rub the pork with the 2 tbsp extra-virgin olive oil until it's evenly coated. This creates a barrier that locks in moisture while developing flavor. Then season aggressively with the 1.5 tsp kosher salt and 1 tsp freshly ground black pepper, pressing the seasoning into the meat so it adheres well. Let the seasoned pork sit at room temperature for 15 minutes while you prep the aromatics.
Build the Flavor Base in the Instant Pot
In your Instant Pot, add the 6 smashed garlic cloves, 0.5 tsp chopped fresh rosemary, and 0.5 tsp fresh thyme leaves. These herbs and garlic will infuse the pork with incredible depth of flavor during the cooking process. Give them a quick stir to distribute evenly across the bottom of the pot.
Pour in the 1 tbsp apple cider vinegar, which helps tenderize the meat while adding a subtle tang. Then add the 0.5 cup low-sodium chicken broth and 1 cup water. The liquid should come about halfway up the sides of the pork when placed in the pot. This moisture level ensures perfect cooking without making the meat soggy.
Sear the Pork for Crispy Perfection
Place the pork loin roast into the Instant Pot, fat-side up if there's any remaining fat cap. Set your Instant Pot to "Sauté" mode and let it heat up for 2 minutes. Then carefully place the trivet over the liquid and position the pork on top. The pork should be elevated about 1 inch above the liquid to prevent steaming.
Once the pot is hot, you'll hear a sizzling sound—this means it's ready to sear. Let the pork cook undisturbed for 3-4 minutes until it develops a golden-brown crust on all sides. This step creates that restaurant-quality exterior we're after. Don't be tempted to move it around; patience here ensures even browning.
Pressure Cook to Juicy Perfection
After searing, pour the 1 tbsp honey over the pork—this will caramelize during cooking, adding natural sweetness and gloss. Then secure the lid and set the Instant Pot to "High Pressure" for 25 minutes. This cooking time guarantees the pork reaches an internal temperature of 145°F, perfect for juicy, tender meat.
During this time, the pressure build-up creates an environment where the pork cooks evenly and retains all its natural juices. I always check the pressure indicator to ensure it's properly sealed before starting the cooking cycle. Once the time is up, allow a natural release for 10 minutes before quick-releasing any remaining pressure.
Create a Glossy Finish and Garnish
Remove the pork from the Instant Pot and place it on a cutting board. Let it rest for 10 minutes—this crucial step allows the juices to redistribute throughout the meat. While it rests, return the cooking liquid to the pot and place it over medium heat.
Whisk together the 1 tbsp cornstarch with 2 tbsp of the cooking liquid to create a slurry. Slowly stir this into the remaining liquid in the pot. The sauce will thicken and become glossy within 2-3 minutes. Pour this sauce over the sliced pork before serving, then garnish with the 0.25 cup chopped fresh parsley for a pop of color and freshness.
Pro Tips For Making Boneless Pork Loin Roast Instant Pot
- SEAR FIRST, THEN SLOW: Use the Instant Pot’s sauté function to sear the pork loin in olive oil over high heat for 3–4 minutes per side—don’t rush it. That crust locks in flavor and keeps the meat juicy when it finishes cooking low and slow.
- SALT THE PORK LOIN 24 HOURS EARLY: Skip the last-minute salting. Pat the pork dry, then season generously with kosher salt (about 1 teaspoon per pound) and refrigerate uncovered. The salt penetrates deeper, and the surface gets properly dry for a better sear.
- DON’T OVERFILL THE POT: Leave at least 1 inch of space between the pork and liquid (or steam) when sealing. I learned this the hard way—crowding traps steam, turning your roast into a soggy mess. If using broth, use just ½ cup.
- SMASH THE GARLIC CLOVES: Instead of mincing, smash whole garlic cloves with the flat side of a knife before adding them to the pot. They infuse flavor more evenly without burning, and you won’t waste time dealing with minced garlic that sticks to the bottom.
Flavor customization for this dish
Herb Variations
Swap out rosemary and thyme for fresh sage and marjoram to create a Tuscan-inspired flavor profile. Use 0.5 tsp each of finely chopped sage and marjoram leaves, and reduce the garlic to 4 cloves for a more delicate balance.
The sage adds a warm, earthy depth that pairs beautifully with the honey glaze. 🌿
Spicy Kick
For heat lovers, add 1 tbsp smoked paprika and ½ tsp cayenne pepper to the pork rub before searing. The paprika enhances the crust's color while the cayenne delivers subtle heat.
For extra smokiness, replace the apple cider vinegar with 1 tbsp chipotle powder dissolved in 1 tbsp water. This transforms your roast into a Carolina-style masterpiece. 🌶️
Sweet and Tangy
Boost the sweet-tangy profile by replacing the honey with 1 tbsp brown sugar and adding 1 tsp Dijon mustard to the pork rub. The mustard adds complexity while the brown sugar caramelizes beautifully during searing.
For a fruity twist, swap the chicken broth for ½ cup apple juice—this creates a bright, almost pork tenderloin-style finish. 🍎
Umami Bomb
Transform this into a restaurant-quality dish by adding 1 tsp fish sauce to the cooking liquid and 1 tbsp soy sauce to the pork rub. The umami depth elevates every bite, especially when paired with the honey glaze.
For extra richness, stir 1 tsp miso paste into the cornstarch slurry before thickening the sauce. This variation works exceptionally well with Asian-inspired sides like gingered green beans. 🍜
Citrus Zest
Brighten the flavor with zested orange peel (about 1 tbsp) mixed into the olive oil rub. Add 1 tsp orange zest to the cooking liquid as well for a cohesive citrus note.
The acidity cuts through the richness, making each bite refreshing. For a stronger citrus profile, replace the apple cider vinegar with 1 tbsp fresh lemon juice. 🍊
Cheesy Crust Option
For a decadent twist, sprinkle ½ cup shredded Gruyère cheese over the pork after searing. As it pressure cooks, the cheese melts into a golden, gooey crust that clings beautifully.
Use Swiss cheese instead for a nuttier flavor, or Parmesan for a saltier finish. This variation works especially well with roasted potatoes or a fresh arugula salad. 🧀

Frequently asked questions
Why does the recipe specify a natural release instead of quick release?
Natural release for 10 minutes after pressure cooking is critical for pork roasts. This gradual pressure drop prevents moisture loss, ensuring your meat stays juicy and tender. Quick releasing can dry out the pork, especially since boneless loin is leaner than bone-in cuts. The 145°F internal temperature is perfect when achieved this way.
Can I make this recipe with a smaller or larger pork loin?
For 1.5 lb pork, reduce cooking time to 20 minutes high pressure. For 3 lb or larger, increase to 30 minutes high pressure. Always use a meat thermometer to check for 145°F internal temp. Larger roasts may need an extra 5 minutes of natural release time. Adjust liquid accordingly—½ cup extra per pound beyond 2 lb.
What's the best way to reheat leftovers?
Slice leftovers and reheat in the Instant Pot with 2 tbsp broth on high for 3-4 minutes (no pressure needed). For oven reheating, cover with foil and bake at 325°F for 15 minutes. Never microwave—it turns pork rubbery. The cornstarch sauce reheats beautifully too; just add a splash of water to loosen.
Why does my pork come out dry even following the recipe?
Most common causes: overcooking (check your 145°F temp), not resting the meat (10 minutes is non-negotiable), or using bone-in pork which cooks faster. Always pat the pork completely dry before seasoning—moisture on the surface steams instead of sears. If using a cheaper cut, add 1 tbsp olive oil to the cornstarch slurry for extra moisture.
What sides pair best with this Instant Pot pork roast?
Classic pairings: garlic mashed potatoes (use the cooking liquid for creaminess), apple sauce (the vinegar in the pork complements it perfectly), or roasted Brussels sprouts with bacon. For a lighter option, try quinoa salad with citrus vinaigrette. The honey glaze also works beautifully with creamy polenta or buttery egg noodles.
