Ingredients for boneless pork loin instant pot
Restaurant-quality pork loin requires just twelve ingredients for perfect pressure-cooked juiciness.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin 🥩 | 1 ½ lb | Center-cut for even cooking |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
| Garlic Cloves 🧄 | 4 cloves | Minced for marinade |
| Dijon Mustard 🍯 | 1 tbsp | High-quality for flavor |
| Dry White Wine 🍷 | ¼ cup | Sauvignon Blanc preferred |
| Low-Sodium Soy Sauce 🥢 | 1 tbsp | For umami depth |
| Honey 🍯 | 1 tbsp | Wildflower preferred |
| Salt 🧂 | 1 tsp | Diamond Crystal kosher |
| Black Peppercorns 🌶️ | ½ tsp | Freshly ground |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped, for aroma |
| Water 💧 | 1 cup | For Instant Pot |
| Instant Pot 🍲 | 1 whole | 6-quart model preferred |
The pork loin cut is critical—center-cut ensures even cooking and minimal connective tissue. Buy from the butcher counter if possible; pre-packaged loin often has more fat. Costco or Whole Foods carry excellent quality, but any reputable grocer will do. Look for a piece with even thickness (about 1.5 inches) and minimal silver skin. Trim any excess fat before cooking, but leave a thin layer for flavor. The 6-quart Instant Pot is ideal for this recipe—smaller models may not accommodate the pork comfortably.
No white wine? Chicken or vegetable broth works perfectly—just add a splash of vinegar for acidity. Short on Dijon? Yellow mustard or whole-grain mustard adds similar tang. The honey can be swapped for maple syrup, though it will change the flavor profile slightly. Fresh rosemary unavailable? Dried rosemary at one-third the amount suffices. For extra depth, add a pinch of smoked paprika to the marinade. The garlic should be minced finely—a microplane works best for even distribution.
This pork reheats beautifully—10-15 seconds in the microwave or until steaming hot. Store leftovers in an airtight container for up to 4 days in the fridge or 3 months frozen. For meal prep, slice against the grain and portion into containers. The marinade can be made 24 hours ahead—store it in the fridge until ready to use. Always let the Instant Pot release pressure naturally for the best texture.
Why You'll Love This Recipe

Step-by-step instructions for boneless pork loin in the Instant Pot
Master this pressure-cooking technique for perfectly tender, flavorful pork every time.
Prepare the Pork and Marinade
Pat the 1.5 lb boneless pork loin dry with paper towels—this ensures maximum browning and crispiness later. Place it in a bowl and rub with 2 tbsp olive oil until evenly coated. In a small bowl, whisk together the 4 cloves minced garlic, 1 tbsp Dijon mustard, 0.25 cup dry white wine, 1 tbsp low-sodium soy sauce, 1 tbsp honey, 1 tsp salt, 0.5 tsp freshly ground black peppercorns, and 1 tbsp chopped fresh rosemary. Pour this marinade over the pork and toss gently to coat completely. Let it sit at room temperature for 15 minutes while you prepare the Instant Pot.
Here's the thing—this marinade does double duty. The wine and soy sauce tenderize the meat while infusing it with deep umami flavor, and the honey caramelizes slightly during cooking, adding a subtle sweetness that balances the savory notes. Don't skip the room-temperature step; cold meat cooks unevenly in the pressure cooker.
Sear the Pork for Maximum Flavor
Set your 6-quart Instant Pot to the "Sauté" function and allow it to heat for 2 minutes. Add the pork loin to the pot and sear on all sides until you achieve a deep golden brown color—about 3-4 minutes per side. You'll know it's ready when the exterior releases easily from the pot and the internal temperature reaches 140°F when checked with an instant-read thermometer.
This searing step is non-negotiable for developing the Maillard reaction, which creates that rich, caramelized flavor. If you're concerned about the pork releasing too much liquid during searing, blot it again with paper towels before proceeding. The residual marinade will prevent sticking while still allowing for proper browning.
Pressure Cook to Perfect Tenderness
Once the pork is seared, carefully pour in 1 cup water to create steam. Secure the lid, ensuring the valve is set to "Sealing." Select the "High Pressure" setting and cook for 20 minutes. The Instant Pot will take about 10 minutes to come to full pressure before the cooking time begins.
During this time, the high-pressure environment breaks down connective tissue while retaining moisture, resulting in meat that's fork-tender but never mushy. I always check the internal temperature after 20 minutes—it should read between 195-205°F. If it's under 190°F, add 5 more minutes of pressure cooking time. The meat will continue cooking slightly during the natural pressure release.
Natural Release and Resting
Once the cooking cycle completes, allow the Instant Pot to perform a natural pressure release for 15 minutes. This slow release ensures the pork stays moist and juicy rather than drying out. After the release, carefully open the lid, remove the pork, and let it rest on a cutting board for 10 minutes. Tent loosely with aluminum foil to keep it warm during this time.
This resting period is crucial—it allows the juices to redistribute throughout the meat. If you skip this step, you'll end up with slices that release their juices onto your plate instead of staying within the fibers. Use this time to prepare your serving plates and any complementary sides.
Slice and Serve with Pan Sauce
After resting, slice the pork loin into ½-inch thick medallions against the grain for maximum tenderness. Return the pork to the Instant Pot and set it back to the "Sauté" function. Add the 1 cup water from the cooking process and scrape up any browned bits from the bottom with a wooden spoon. Simmer for 3-4 minutes until the liquid reduces slightly to create a glossy pan sauce.
Serve the pork immediately with the pan sauce spooned over the top. Each slice should be fork-tender with a slightly caramelized exterior from the searing. The sauce should coat the back of a spoon and complement the pork's rich, herby-sweet flavor profile. For best results, pair with roasted vegetables or a fresh salad to balance the dish.
Pro Tips For Making Boneless Pork Loin Instant Pot
- SEAR FIRST, THEN SAUCE: I used to toss everything in raw and walk away—big mistake. Sear the pork loin in the Instant Pot for 2-3 minutes with olive oil and garlic first. The crust locks in flavor and keeps the meat from drying out later, especially when that wine gets added.
- SLICE THIN GARLIC: Whole cloves? Nope. Smash or finely mince those garlic cloves before adding them to the pot. Whole cloves stay stubbornly intact, while minced garlic dissolves into the wine and mustard, giving you that deep, aromatic base you actually want.
- DON’T SKIP THE REST: That pork loin needs 5-10 minutes off-heat under foil before slicing. I know, you’re eager—so was I. But cutting it too soon means juices pool on your plate instead of staying where they belong: inside the meat.
- UPGRADE WITH A SPLASH OF BROTH: The wine’s great, but if you’re using a dry one, add ¼ cup chicken or vegetable broth too. It keeps the sauce from evaporating into nothingness and adds depth without altering the flavor profile. (Yes, even if you’re impatient like me.)
Flavor customization for these flavors
Sweet and Tangy
For a bright, fruity twist, add 1 tbsp orange zest and 2 tbsp orange juice to the marinade along with the white wine. The citrus cuts through the richness while adding a refreshing pop.
I like to finish with a drizzle of honey-glazed reduction made by simmering 2 tbsp honey with 1 tbsp apple cider vinegar until thickened. This works especially well with roasted sweet potatoes or a citrus salad. 🍊
Herb-Infused Variations
Swap out rosemary for thyme and sage for a more earthy flavor profile. Use 1 tbsp each of fresh thyme leaves and chopped sage in the marinade, plus ½ tsp ground coriander for warmth.
This combination pairs beautifully with roasted carrots and mashed cauliflower. For a Mediterranean touch, add ½ tsp dried oregano and a pinch of red pepper flakes.
Spicy Kick
Transform this into a spicy pork loin by adding 1 tbsp gochujang or 1 tbsp sriracha to the marinade. For extra heat, include 1 tsp cayenne pepper or 1 chopped Fresno chili pepper.
Serve with a cooling side like cucumber salad or rice to balance the heat. I recommend using Penzeys brand chili flakes for consistent spice levels. 🌶️
Smoky BBQ Style
Create a smoky BBQ-inspired version by replacing the white wine with ½ cup BBQ sauce (like Sweet Baby Ray's Original) and adding 1 tsp smoked paprika and ½ tsp garlic powder to the marinade.
After cooking, brush the slices with additional BBQ sauce and broil for 2-3 minutes to caramelize. Serve with baked beans or coleslaw for a full Southern-style meal.
Garlic and Ginger
For an Asian-inspired twist, increase the garlic to 6 cloves and add 1 tbsp freshly grated ginger along with 1 tbsp rice vinegar and 1 tsp sesame oil to the marinade.
Finish with a sprinkle of toasted sesame seeds and serve with steamed jasmine rice or stir-fried bok choy. This variation works especially well when paired with a miso-glazed sauce. 🧄
Cheesy and Creamy
Add a rich, creamy element by including 2 tbsp cream cheese and ½ cup shredded Gruyère cheese in the marinade. After cooking, top each slice with extra cheese and broil for 1-2 minutes until melted.
This decadent version pairs perfectly with roasted Brussels sprouts or a creamy polenta. For extra indulgence, drizzle with a balsamic reduction made from 2 tbsp balsamic vinegar** reduced by half.

Frequently asked questions
Can I use a different cut of pork instead of boneless pork loin?
While boneless pork loin is ideal for this recipe, you can use pork tenderloin as a substitute—it cooks even faster (15 minutes at high pressure). For pork shoulder or pork butt, increase cooking time to 45-60 minutes and use the marinade as a braising liquid. These cuts will be more tender but require longer pressure cooking.
Why does my pork turn out dry even after using the Instant Pot?
Dry pork usually means the internal temperature exceeded 205°F or the natural release was skipped. Always check the temperature with a meat thermometer (195-205°F is perfect) and never quick-release—always do a 15-minute natural release. Overcooking happens fast in pressure cookers, so follow the 20-minute high pressure guideline closely.
Can I make this recipe without white wine?
Replace the white wine with ¼ cup chicken or vegetable broth plus 1 tbsp apple cider vinegar for acidity. The marinade will still tenderize the meat and add depth. For a non-alcoholic option, use ¼ cup pineapple juice—the natural enzymes help break down fibers, making the pork even more tender.
How do I reheat leftover pork loin?
Reheat slices in the Instant Pot using the \"Sauté\" function with 2 tbsp water for 3-4 minutes until steaming. For microwave reheating, place slices on a plate with 1 tsp water, cover with a damp paper towel, and heat for 20-30 seconds. Never reheat dry—moisture keeps the meat juicy. Store leftovers in an airtight container for up to 4 days.
What's the best way to serve this Instant Pot pork loin?
Pair it with roasted root vegetables (carrots, parsnips) or creamy mashed potatoes to balance the rich flavors. For a lighter option, serve with a spring greens salad dressed in lemon vinaigrette. The pan sauce from the recipe works perfectly as a drizzle—simply reduce the cooking liquid by 3-4 minutes on \"Sauté\" mode for extra richness.
