Bone In Pork Loin Instant Pot Recipe: Fall-Off-The-Bone Tender with Herb Crust

This Instant Pot method transforms a bone-in pork loin into a melt-in-your-mouth masterpiece with minimal effort.

By searing the meat first, you lock in juices while the herb crust develops deep, aromatic flavors. The pressure cooker then works its magic, breaking down the meat to fall-off-the-bone tenderness in a fraction of traditional cooking time.

What results is a perfectly cooked pork loin with a golden, herb-infused crust and juices that pool enticingly on your plate. The bone adds extra depth to the flavor, making every bite rich and satisfying.

This technique delivers restaurant-quality results with the convenience of a one-pot meal. The herb crust ensures each serving is as flavorful as it is tender.

Ingredients for Bone in Pork Loin Instant Pot

A bone-in pork loin and pantry herbs create this restaurant-worthy dish effortlessly.

The pork loin is the star here. Bone-in, center-cut from a reputable butcher (I go to Whole Foods or a local shop) ensures even cooking and maximum flavor. Look for good marbling—this keeps the meat juicy. The dried herbs need to be fresh (Penzeys or bulk bins at natural food stores are great) or they won’t deliver that aromatic punch the crust needs.

No bone-in loin? Boneless pork loin at the same weight works in a pinch, but reduce cook time by 5 minutes. Out of Dijon? Regular yellow mustard is fine, though the flavor will be milder. Chicken broth can be swapped for vegetable broth—just check it’s not too salty. Fresh herbs? Use double the amount of dried, but stick to thyme and rosemary for consistency.

Leftovers keep beautifully in the fridge for up to 4 days—the flavors actually deepen. Freeze for 3 months if you’ve got extras. Reheat gently in a saucepan with a splash of broth to keep it moist (microwave works too, just cover it).

Step-by-Step Instructions for Bone-In Pork Loin in Instant Pot

This method guarantees that fall-off-the-bone tenderness with minimal hands-on time.

Step 1: Season and Sear the Bone-In Pork Loin

Pat the 3 lb Bone-In Pork Loin dry with paper towels. In a small bowl, combine the 1.5 tsp Kosher Salt, 1 tsp Freshly Ground Black Pepper, 2 tsp Dried Thyme, 2 tsp Dried Rosemary, 1 tbsp Garlic Powder, and 1 tbsp Onion Powder. Rub this mixture all over the pork loin, pressing it into the meat so it adheres well.

Set your Instant Pot to the “Sauté” function and add 1 tbsp Olive Oil. Once hot, sear the pork loin on all sides until deep golden brown, about 3-4 minutes per side. This step builds a flavorful crust and enhances the overall taste. Remove the pork and set it aside temporarily.

Step 2: Deglaze and Build the Cooking Liquid

With the Instant Pot still on “Sauté,” add the remaining 1 tbsp Olive Oil and the minced 4 cloves Fresh Garlic Cloves. Sauté for 30 seconds until fragrant—just until the garlic starts to turn golden but not brown. Immediately pour in the 1 cup Chicken Broth and 1 tbsp Dijon Mustard, using a wooden spoon to scrape up all the browned bits from the bottom of the pot.

These browned bits, or fond, are packed with flavor and will dissolve into the cooking liquid, creating a rich base for the pork. Stir to combine the broth and mustard fully, ensuring the bottom of the pot is completely deglazed to prevent any burning during pressure cooking.

Step 3: Pressure Cook to Tender Perfection

Return the seared pork loin to the Instant Pot, placing it directly into the liquid. Add the 2 whole Fresh Rosemary Sprigs for an aromatic touch. Secure the lid, set the valve to “Sealing,” and cook on “High Pressure” for 45 minutes for 3 lb of pork.

The pork is done when it reaches an internal temperature of 145°F, but the pressure cooking process will naturally bring it to a tender, pull-apart consistency. Once the cooking time is complete, allow the pressure to release naturally for 15 minutes, then quick-release any remaining pressure. This natural release helps the meat retain moisture.

Step 4: Finish with Butter and Rest

Carefully remove the pork loin from the Instant Pot and place it on a cutting board. Stir the 2 tbsp Butter into the cooking liquid until melted, creating a silky sauce. You can use this sauce for serving or as a base for gravy if desired.

Tent the pork loosely with foil and let it rest for 10 minutes before slicing. Resting allows the juices to redistribute, ensuring every bite is moist and flavorful. Slice against the grain and serve with the pan sauce for a dish that’s both impressive and effortless.

Essential Equipment for Great bone in pork loin instant pot

Instant Pot Model

I recommend using a 6-quart or 8-quart Instant Pot for this recipe. The 6-quart works perfectly for a 3 lb bone-in pork loin with room for proper searing and pressure cooking. I use my Instant Pot Duo Crisp + Air Fryer for this recipe. 💡

Wooden Spoon

A sturdy wooden spoon is essential for deglazing the pot after searing the pork. It helps scrape up all the flavorful browned bits without damaging your Instant Pot’s non-stick coating. I keep a dedicated wooden spoon just for my pressure cooker.

Tongs

Use 12-inch locking tongs to safely turn the pork loin during searing and to remove it from the pot after cooking. The locking feature helps with storage, and the length keeps your hands away from the heat. I prefer OXO Good Grips for their comfort and durability.

Meat Thermometer

While the Instant Pot does the work, I always verify doneness with a digital meat thermometer. For pork loin, you want an internal temperature of 145°F. I use the ThermoWorks ThermoPop for its accuracy and quick readings. 🌡️

Cutting Board

A large cutting board with a groove to catch juices is ideal for resting and slicing the pork loin. I recommend a bamboo board as it’s gentle on knives and naturally antimicrobial. The groove helps contain the delicious juices for serving.

Paper Towels

Keep paper towels handy for patting the pork loin dry before seasoning and for cleaning up any spills during the searing process. Dry meat sears better, creating that perfect crust. I always have a roll within reach when cooking.
