Pork Bone Broth Recipe Instant Pot: Rich Collagen-Packed Elixir in Hours

This Instant Pot method transforms pork bones into a rich, collagen-packed broth in a fraction of traditional cooking time. The pressure cooker extracts maximum flavor and nutrients that normally require days of simmering.

I developed this technique after realizing most home cooks don’t have hours to monitor a stockpot. The sealed environment builds intense pressure, breaking down connective tissues and marrow for a deeply flavorful result.

You’ll end up with a golden liquid that gels when cooled, proof of its high collagen content. The broth works beautifully as a base for soups, risottos, or simply sipped as a nourishing tonic.

With just 4 hours of cooking time and minimal prep, this delivers professional-quality results without the wait. The process is nearly hands-off once started.

Ingredients for Pork Bone Broth Recipe Instant Pot

Transform pork bones and vegetables into a deeply nourishing broth with these essential ingredients.

The bones are the foundation. Pork marrow and knuckle bones yield the most collagen and gelatin—ask your butcher for grass-fed or pasture-raised if available. Most Whole Foods or specialty grocers will have these pre-cut. Avoid pre-cooked bones (like smoked ham hocks) as they won’t produce the same gelatinous result. The onion skin adds natural color, so leave it on despite the rustic appearance.

No pork bones? Beef or chicken bones work in a pinch, though cooking times may vary. For a lighter flavor, use half the quantity of aromatic vegetables. Apple cider vinegar can be swapped for white vinegar or lemon juice—the acidity is key for mineral extraction. If you’re missing fresh thyme, 1 tsp dried thyme infuses just as well. This recipe is forgiving with herb substitutions.

The broth gels beautifully when cooled—a sign of high collagen content. Strain and store in airtight containers for up to 5 days in the fridge or 6 months in the freezer. For convenience, portion into 1-cup servings before freezing. Reheat gently to preserve the delicate texture and nutrients.

Step-by-Step Instructions for Pork Bone Broth

This method transforms simple ingredients into a rich, collagen-packed elixir with minimal effort.

Step 1: Prepare and Roast the Bones and Vegetables

Place the 2 lb Pork Bones on a baking sheet and roast in a preheated 400°F oven for 20-25 minutes until deeply browned. This caramelization enhances the depth of flavor in your broth. Meanwhile, quarter the 1 whole Yellow Onion (leave the skin on for color), roughly chop the 2 whole Carrots and 2 whole Celery Stalks, and smash the 4 cloves Garlic Cloves (skin on).

Roasting the bones and vegetables intensifies their natural sweetness and creates a robust foundation for your broth. You’ll notice the bones develop a rich, golden-brown hue, and the vegetables will soften slightly and release their aromas.

Step 2: Deglaze and Pressure Cook

Transfer the roasted bones and vegetables to the Instant Pot. Pour in the 2 tbsp Apple Cider Vinegar and use a wooden spoon to scrape up any browned bits from the baking sheet—this adds another layer of flavor. Add the 1 whole Yellow Onion, 2 whole Carrots, 2 whole Celery Stalks, 4 cloves Garlic Cloves, 2 whole Bay Leaves, 1 tsp Black Peppercorns, and 4 whole Fresh Thyme Sprigs.

Pour in the 12 cups Cold Water, ensuring the bones are fully submerged. Secure the lid, set the valve to sealing, and cook on high pressure for 3 hours. The long cook time extracts collagen, gelatin, and minerals from the bones, creating a rich and nutritious broth.

Step 3: Release Pressure and Strain

Allow the pressure to release naturally for 20 minutes, then carefully switch the valve to venting to release any remaining pressure. This gradual release prevents the broth from boiling over and ensures safety. Once the pressure is fully released, open the lid and let the broth cool slightly.

Place a fine-mesh strainer over a large bowl or pot and carefully pour the broth through to remove all solids. Discard the bones and vegetables—they’ve given up all their goodness. You’ll be left with a deep amber liquid that’s rich in collagen and flavor.

Step 4: Season and Store

Stir in the 1 tsp Sea Salt and taste. Adjust the seasoning as needed, though remember the broth will reduce slightly when reheated. For a clearer broth, you can skim off any fat that rises to the surface once it cools.

Let the broth cool to room temperature, then transfer it to airtight containers. It will keep in the refrigerator for up to 5 days or in the freezer for up to 6 months. The broth will gel when chilled, a sign of its high collagen content—a hallmark of a well-made bone broth.

Common Mistakes When Making Perfect Results

Skipping the Roast

I know it’s tempting to skip roasting the bones to save time, but this step is crucial. Roasting at 400°F for 20-25 minutes develops deep, caramelized flavors that raw bones simply can’t provide. The Maillard reaction creates complex flavor compounds that make your broth rich and satisfying.

Overfilling the Pot

Never exceed the 2/3 max fill line in your Instant Pot. With 2 lb pork bones and vegetables, you’re already pushing the limit. Overfilling risks clogging the pressure valve or worse—creating a safety hazard. I learned this the hard way when my first batch nearly overflowed.

Using the Wrong Bones

Avoid pre-cooked bones like ham hocks—they won’t yield the same gelatinous result. Stick with marrow or knuckle bones for maximum collagen extraction. I ask my butcher for grass-fed pork bones when available. They produce a cleaner, more flavorful broth.

Also, don’t use bones that have been previously boiled—they’ve already released most of their goodness.

Skipping the Vinegar

Those 2 tbsp apple cider vinegar aren’t just for flavor. The acidity helps extract minerals from the bones, making your broth more nutritious. I’ve tried batches without it, and the difference in mineral content is noticeable. White vinegar or lemon juice work too.

Rushing the Release

Let the pressure release naturally for at least 20 minutes. Quick releasing can cause the broth to foam up and potentially clog your valve. I set a timer and walk away—patience pays off with a clearer, more settled broth. 💡

Over-seasoning Early

Wait to add the 1 tsp sea salt until after cooking. As the liquid reduces, flavors concentrate, and what tasted perfect initially can become overpowering. I always taste and adjust at the end. This way, you can control the final seasoning precisely.
