Boneless Pork Roast Instant Pot Recipe: Pressure-Cooked Tender in 60 Minutes

This boneless pork roast Instant Pot recipe transforms tough cuts into melt-in-your-mouth perfection in just 60 minutes—no slow cooker or oven required. The secret lies in high-pressure cooking, which breaks down fibers while preserving juices, ensuring every bite is tender and flavorful.

I’ve tested this method countless times, and it consistently delivers results that rival traditional roasting methods.

The process is straightforward: sear the pork first for caramelized crust, then pressure-cook with aromatics and liquid to infuse deep flavor. Unlike slow cooking, the Instant Pot locks in moisture while tenderizing the meat efficiently.

This method is ideal for busy weeknights or meal prep, as it requires minimal hands-on time and delivers restaurant-quality results.

What you’ll end up with is a juicy, fork-tender pork roast that practically falls apart, ready to slice for sandwiches, tacos, or salads. The versatility of this dish makes it perfect for feeding a family or preparing ahead—simply reheat and serve.

The key is patience during the pressure release, which ensures the meat stays moist and flavorful.

Pair it with roasted vegetables, mashed potatoes, or a fresh salad for a complete meal. The beauty of this recipe is its adaptability—use it for everyday dinners or special occasions without the fuss of traditional roasting. Let’s get started on creating your tender, pressure-cooked pork roast.

Ingredients for boneless pork roast instant pot

High-pressure cooking unlocks restaurant-quality tenderness from simple pantry ingredients and fresh aromatics.

The pork roast cut matters—center-cut stays juicier than shoulder cuts. Costco or Whole Foods carry pre-trimmed boneless roasts that cook evenly. Look for good marbling, but avoid anything with excessive fat. For the aromatics, fresh rosemary from the grocery store’s produce section (not dried) adds a piney depth that dried can’t match. Pre-sliced carrots work in a pinch, but whole carrots peeled and cut into even rounds ensure consistent cooking. The beef broth should be low-sodium—Swanson or Pacific Foods are reliable brands that won’t overpower the dish.

No beef broth? Chicken broth plus 1 tsp soy sauce works perfectly. Fresh thyme unavailable? Dried at one-third the amount suffices, but toast the dried thyme in a dry pan for 30 seconds first to wake up the flavor. Substituting apple cider vinegar? White vinegar or lemon juice both work, though apple cider adds subtle sweetness. The Instant Pot’s steam release is critical—natural release for 15 minutes after cooking prevents the meat from drying out. For extra richness, add 1 tbsp of brown sugar to the broth during cooking, but omit if you prefer a cleaner flavor profile.

This roast reheats beautifully—simply add 2 tbsp broth and cook on high for 5 minutes. Store leftovers in the fridge for 4 days or freeze for 3 months by wrapping tightly in parchment paper. For meal prep, slice the roast against the grain and portion into containers with 1 tbsp of the cooking juices to keep it moist. The aromatics (onion, carrots, garlic) can be prepped ahead and stored in the fridge for 3 days before cooking, saving you time on busy days.

Step-by-step instructions for pressure-cooked boneless pork roast

Transform a simple boneless pork roast into melt-in-your-mouth perfection using your Instant Pot.

Begin by heating the Instant Pot on the "Sauté" function with 2 tablespoons olive oil until shimmering. Pat the 2 lb boneless pork roast thoroughly with paper towels—this ensures a proper sear. Place the roast in the pot and sear on all sides for 3-4 minutes per side until developing a deep golden-brown crust.

I press down gently on the roast during the first minute of searing—this prevents it from curling and ensures even contact with the pan. The crust forms the flavor foundation, so don't rush this step. Once browned, remove the pork and set it aside on a plate.

In the same Instant Pot, add the quartered yellow onion, peeled and sliced carrots, and smashed garlic cloves. Sauté for 3-4 minutes until the onions soften slightly and the garlic releases its signature aroma. This step develops the base flavors that will infuse the pork during cooking.

I like to stir occasionally but avoid overcrowding the pot—this ensures everything gets properly browned. The vegetables will continue cooking later, so they don't need to be fully tender yet. Once fragrant, add the 1 tablespoon apple cider vinegar and let it cook for another 30 seconds to mellow its sharpness.

Return the seared pork roast to the Instant Pot. Add the 1.5 cups beef broth, 1 teaspoon dried thyme, 1.5 teaspoons salt, 0.5 teaspoon black peppercorns, 2 whole bay leaves, and 0.25 cup chopped fresh rosemary. Stir gently to combine all ingredients, ensuring the pork is fully submerged in the liquid.

Secure the lid, set the valve to "Sealing," and select the "High Pressure" function for 45 minutes. The Instant Pot will automatically shift to "Natural Release" for 10 minutes once cooking completes. This pressure cooking method guarantees tender, juicy pork without drying it out.

After the natural release completes, carefully remove the lid and use tongs to transfer the pork roast to a cutting board. Let it rest for 10-15 minutes before slicing—this allows the juices to redistribute throughout the meat, ensuring each bite remains moist. The internal temperature should reach 203°F when measured with a meat thermometer.

While resting, skim any excess fat from the cooking liquid if desired. The vegetables should be tender but still hold their shape. If you prefer a thicker sauce, you can reduce the liquid on the "Sauté" function for 2-3 minutes after removing the pork. Serve the pork sliced over the vegetables with any pan juices spooned on top.

Dietary considerations for this recipe

Gluten-Free Adaptations

This recipe is naturally gluten-free since it relies on pork, broth, and fresh vegetables. The only potential concern is the beef broth—always check the label for hidden gluten additives.

I recommend Pacific Foods gluten-free beef broth to ensure safety. The apple cider vinegar and all spices are also gluten-free, so no substitutions are needed. 🌱

Low-Carb and Keto

For a low-carb or keto version, skip the carrots and onions if you're strict about carbs, or reduce them to 1 tablespoon each. The pork roast itself is naturally keto-friendly, containing only 0.5g net carbs per 3-ounce serving.

The beef broth should be low-sodium and sugar-free. This makes the dish perfect for anyone following a keto or carnivore diet while still delivering rich, satisfying flavors.

Dairy-Free Considerations

This recipe doesn’t contain any dairy naturally, making it safe for those avoiding lactose. However, if you plan to serve it with sides like mashed potatoes or cream-based sauces, opt for dairy-free alternatives.

For example, use olive oil or coconut milk instead of butter in mashed potatoes. The pork and broth remain completely dairy-free, so no adjustments are needed to the main dish itself.

Allergen-Friendly Tips

For nut allergies, this recipe is already safe—no nuts are used. If you have soy allergies, avoid soy-based broths and stick with beef or chicken broth. For egg allergies, no eggs are included.

The only potential cross-contamination risk comes from shared kitchen tools, so clean your Instant Pot thoroughly before use if allergies are a concern. Always double-check spice blends for hidden allergens like soy or wheat.

Protein-Packed Boost

This recipe delivers 40g of protein per serving (based on a 4-serving recipe), making it ideal for muscle recovery or high-protein diets. For even more protein, add 1 cup of cooked quinoa or lentils to the Instant Pot during the final 10 minutes of cooking.

Both grains absorb flavor beautifully and add fiber without compromising the pork’s tenderness. 💪
