The pork loin is the star—select a well-marbled, boneless cut from a trusted butcher or Whole Foods for optimal tenderness. Avoid pre-brined versions, as they can skew the seasoning balance. Diamond Crystal sea salt (available at most supermarkets) dissolves more evenly than table salt, which is critical for dry brining. For the herbs, Penzeys offers exceptional quality dried rosemary and thyme with vibrant color and aroma.

No garlic powder? Fresh minced garlic at triple the amount works, but may burn during searing—add it with the broth instead. Swap onion powder for 1 tbsp grated fresh onion, sautéed briefly first. If avoiding dairy, replace butter with avocado oil (already in the recipe) or ghee. Chicken broth can be beef broth for deeper flavor, but stick to low-sodium to control the dish’s saltiness.

Store raw pork in the fridge for up to 3 days or freeze for 6-12 months. Leftovers keep 4-5 days refrigerated and reheat beautifully. This method also works for pork shoulder—just increase cook time to 60 minutes under pressure.

Step-by-Step Instructions for Keto Pork Loin in Instant Pot

Master the technique for perfectly tender pork loin with a pressure cooker’s efficiency and precision.

Step 1: Season and Sear the Pork Loin

Pat the 2 lb Pork Loin dry with paper towels to ensure a proper sear. Combine the 1.5 tsp Sea Salt, 1 tsp Black Pepper, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 1 tsp Dried Rosemary, and 1 tsp Dried Thyme in a small bowl, then rub this mixture evenly over all surfaces of the pork loin. This dry rub creates a flavorful crust that enhances the meat’s natural richness.

Select the sauté function on your Instant Pot and add the 2 tbsp Avocado Oil. Once the oil shimmers, carefully place the seasoned pork loin in the pot. Sear for 3-4 minutes per side until deeply browned. This step develops a fond that will later infuse the cooking liquid with robust flavor.

Step 2: Deglaze and Pressure Cook

After searing, transfer the pork loin to a plate and pour the 0.5 cup Chicken Broth into the Instant Pot. Use a wooden spoon to scrape up all the browned bits from the bottom of the pot—this deglazing step is critical to avoid a burn notice and to incorporate maximum flavor into the cooking liquid.

Return the pork loin to the Instant Pot, ensuring it’s mostly submerged in the broth. Secure the lid, set the valve to sealing, and cook on high pressure for 25 minutes. The pressure cooker’s sealed environment tenderizes the pork loin while locking in moisture, resulting in a juicy, fall-apart texture.

Step 3: Natural Release and Finishing Touch

Allow the pressure to release naturally for 10 minutes, then carefully switch the valve to venting to release any remaining pressure. This gradual release prevents the pork loin from toughening due to sudden pressure changes.

Once the pressure is fully released, open the lid and transfer the pork loin to a cutting board. Stir the 2 tbsp Butter into the cooking liquid to create a rich, velvety sauce that complements the pork’s savory notes. Let the pork loin rest for 5-10 minutes before slicing to allow the juices to redistribute evenly.

Step 4: Slice and Serve

Slice the pork loin against the grain into ½-inch thick pieces. This ensures each bite is tender and easy to chew. Spoon the buttery cooking liquid over the sliced pork loin before serving to enhance its moisture and flavor.

The pork loin should be fork-tender with a lightly crisp exterior from the sear, and the sauce should be silky and aromatic. Serve immediately for the best texture and temperature.
