Pork Knuckle Recipe Pressure Cooker: Fall-Off-The-Bone Tender in 90 Minutes

Pork knuckle usually takes hours to reach perfect tenderness, but my pressure cooker method delivers fall-off-the-bone results in just 90 minutes. This approach preserves the traditional rich flavor while cutting cooking time dramatically.

I developed this technique after several attempts in my small Boston kitchen, refining the timing and liquid ratios for consistent success. The pressure cooker locks in moisture while breaking down tough fibers, ensuring every bite is juicy and tender.

The result is a dish that maintains the soul of classic pork knuckle with crispy skin and succulent meat, all achieved through modern convenience. No special equipment beyond your pressure cooker is needed.

Serve with traditional sides or as part of a hearty meal. The process is straightforward and reliable.

Ingredients for Pork Knuckle Recipe Pressure Cooker

Pressure cooker magic turns tough pork knuckle into fall-off-the-bone perfection with basic ingredients.

The pork knuckle is the star here. Look for bone-in, skin-on pieces from your butcher or grocery store—the skin crisps up beautifully under the broiler after pressure cooking. I grab mine from Whole Foods or a local butcher shop when possible. The skin needs to be scored before cooking (don’t skip this step). Caraway seeds add that classic flavor, but fennel seeds work in a pinch.

No chicken stock? Use vegetable stock plus a splash of soy sauce for depth. Short on beer? Substitute with more stock and 1 tsp of brown sugar to mimic the maltiness. The apple cider vinegar balances the richness—white wine vinegar works too. For the aromatics, if you’re missing thyme, a pinch of dried thyme (about 1/4 tsp) will do. The onion, carrot, and celery are standard mirepoix—no substitutions needed.

Store raw pork knuckle in the fridge for up to 3 days or freeze for 6 months. Once cooked, it keeps in the fridge for 4 days or freezes beautifully for 3 months. Reheat in the oven to keep the skin crispy (microwave makes it soggy).

Step-by-Step Instructions for Pressure Cooker Pork Knuckle

This method transforms tough pork knuckle into tender perfection in record time.

Step 1: Season and Sear the Pork Knuckle

Pat the pork knuckle dry with paper towels, then score the skin in a crosshatch pattern. Rub all sides aggressively with the coarse kosher salt, freshly cracked black peppercorns, and caraway seeds. I press the spices into the meat to ensure they adhere and penetrate deeply.

Heat the olive oil in your pressure cooker on sauté mode until shimmering. Sear the pork knuckle skin-side down first for 8-10 minutes until the skin turns deep golden brown and crisp. Flip and sear the other side for 5 minutes. This builds deep flavor and creates that coveted crispy skin.

Step 2: Build the Aromatic Base

Remove the pork knuckle and set aside. In the same pot, add the quartered yellow onion, chopped carrots, and celery stalks. Sauté for 3-4 minutes until the onion becomes translucent and the vegetables begin to soften.

Add the smashed garlic cloves, bay leaves, and fresh thyme sprigs. Cook for 1 minute until fragrant. Pour in the apple cider vinegar and deglaze the pot, scraping up all the browned bits from the bottom. These fond bits are pure flavor that will infuse your dish.

Step 3: Pressure Cook to Tender Perfection

Return the pork knuckle to the pot. Pour in the beer, chicken stock, and water, ensuring the liquid reaches your pressure cooker’s minimum line. The beer adds rich maltiness while the chicken stock builds a savory foundation.

Secure the lid and cook on high pressure for 60 minutes. After cooking, let the pressure release naturally for 15 minutes, then quick-release any remaining pressure. The natural release allows the pork knuckle to finish cooking gently in the residual heat, ensuring it becomes fall-off-the-bone tender.

Step 4: Finish and Rest Before Serving

Carefully remove the pork knuckle from the pot. If you want extra-crispy skin, transfer it to a baking sheet and broil for 3-5 minutes until the skin crackles. Watch it closely—broiling can go from perfect to burnt quickly.

Let the pork knuckle rest for 10-15 minutes before carving. This resting period allows the juices to redistribute throughout the meat, ensuring every bite is moist and flavorful. Serve with some of the cooking liquid spooned over the top for added richness.

Best Sauces and Condiments for This pork knuckle recipe pressure cooker

Classic Horseradish Cream

This tangy, creamy sauce cuts through the richness of pork knuckle perfectly. I mix ½ cup sour cream with 2 tbsp prepared horseradish, 1 tsp Dijon mustard, and 1 tsp apple cider vinegar from the recipe. Adjust horseradish to taste—I often add a dash more for extra kick. 🌟

Sweet Mustard Glaze

For a sweeter contrast, combine ¼ cup whole grain mustard with 2 tbsp honey and 1 tbsp brown sugar. Thin with 1 tsp warm water if needed. I love brushing this on the crispy skin right before serving for a beautiful glaze.

Dark Beer Sauce

Use the cooking liquid from your pressure cooker as a base. Strain and reduce it by half, then whisk in 1 tbsp butter and 1 tsp cornstarch slurry for thickness. The beer in the cooking liquid creates a rich, malty sauce that complements the pork beautifully.

Tangy Apple Compote

Simmer 2 diced apples with ¼ cup apple cider vinegar, 2 tbsp brown sugar, and ½ tsp cinnamon for 10-15 minutes until soft. This New England favorite adds bright acidity that balances the fatty pork. I often make extra for leftovers.

Garlic-Herb Butter

Mash 4 tbsp softened butter with 2 minced garlic cloves and 1 tbsp fresh parsley. Roll into a log and chill. Slice a pat onto hot pork knuckle just before serving for an instant flavor boost. It melts beautifully over the crispy skin. 💫
