Ingredients for Bone in Pork Roast Instant Pot
Transform a bone-in pork shoulder with pantry staples and aromatics into pressure-cooked perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Shoulder Roast 🍖 | 3 lb | Boston butt preferred for marbling |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal brand recommended |
| Black Pepper 🌶️ | 1 tsp | Freshly cracked for best flavor |
| Garlic Cloves 🧄 | 6 cloves | Peeled and smashed |
| Yellow Onion 🧅 | 1 whole | Quartered for depth of flavor |
| Fresh Rosemary Sprigs 🌿 | 3 pieces | Woody stems removed |
| Fresh Thyme Sprigs 🍃 | 4 pieces | Woody stems removed |
| Chicken Broth 🥣 | 1 cup | Low-sodium preferred to control salt |
| Apple Cider Vinegar 🍏 | 2 tbsp | Balances richness of pork |
| Dijon Mustard 🟡 | 1 tbsp | Smooth variety for even coating |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for searing |
| Brown Sugar 🟤 | 1 tbsp | Light or dark variety |
| Bay Leaves 🌿 | 2 pieces | Dried, for aromatic depth |
The pork shoulder cut is non-negotiable for this method. Opt for bone-in Boston butt with visible marbling—Costco and Whole Foods consistently stock quality options. Avoid pre-cut pork loin; it lacks the fat and connective tissue needed for that fall-apart texture. A 3-pound roast feeds four generously with leftovers for sandwiches or tacos.
No fresh rosemary or thyme? Dried herbs at one-third the amount work, but add them with the liquid to prevent burning. Chicken broth can be swapped for vegetable broth or water in a pinch. For extra depth, deglaze with 1/2 cup dry white wine instead of vinegar. Apple cider vinegar can be replaced with red wine vinegar for a slightly sharper tang.
Store raw pork in the coldest part of your fridge for up to 3 days before cooking. Leftovers keep well for 4-5 days refrigerated or freeze for up to 3 months. The flavor intensifies overnight, making this even better as leftovers for pulled pork sandwiches or stews.

Step-by-Step Instructions for Bone In Pork Roast Instant Pot
Master pressure cooking with this method designed for tender, fall-apart meat in minimal time.
Step 1: Season and Sear the Pork Shoulder
Pat the 3 lb Bone-In Pork Shoulder Roast dry with paper towels, then rub it evenly with the 1.5 tsp Kosher Salt, 1 tsp Black Pepper, and 1 tbsp Brown Sugar. The sugar will caramelize during searing, creating a rich crust.
Set your Instant Pot to the “Sauté” function and add the 2 tbsp Olive Oil. Once hot, sear the pork on all sides until deep golden brown—about 3-4 minutes per side. This step builds flavor, so don’t rush it. Remove the pork and set aside.
Step 2: Build the Aromatic Base
In the same pot, add the 1 whole Yellow Onion (quartered), 6 cloves Garlic Cloves (smashed), 3 pieces Fresh Rosemary Sprigs, and 4 pieces Fresh Thyme Sprigs. Sauté for 2 minutes until the onions soften and the garlic becomes fragrant.
Pour in the 2 tbsp Apple Cider Vinegar and 1 tbsp Dijon Mustard, stirring to deglaze the pot and lift any browned bits. This ensures no flavor is left behind. Add the 2 pieces Bay Leaves for depth.
Step 3: Pressure Cook to Perfection
Return the pork to the pot and pour in the 1 cup Chicken Broth. Secure the lid, set the valve to “Sealing,” and cook on high pressure for 45 minutes. The pork should reach an internal temperature of 195-200°F for ideal tenderness.
Let the pressure release naturally for 15 minutes, then quick-release any remaining pressure. This gradual release prevents the meat from seizing up and ensures juiciness.
Step 4: Shred and Serve
Remove the pork from the pot and place it on a cutting board. Using two forks, shred the meat into bite-sized pieces, discarding any large fat chunks. The pork should pull apart effortlessly—if it resists, it needs more time under pressure.
Skimming excess fat from the cooking liquid is optional, but I recommend reducing it on the “Sauté” function for 5 minutes to thicken slightly. Pour this over the shredded pork for serving, ensuring every bite is infused with flavor.
Pro Tips For Making Bone In Pork Roast Instant Pot
- Sear the Roast: I learned this the hard way—skipping the sear leaves the pork bland. Use the Instant Pot’s sauté function to brown the roast on all sides before pressure cooking; it adds depth the meat wouldn’t have otherwise.
- Slice the Onion Thin: After burning a batch with thick onion chunks, I finally figured out that thin slices melt into the liquid better, infusing the pork with sweetness without sticking to the bottom.
- Don’t Overfill Liquid: Resist the urge to add extra broth or water—1 cup is plenty for a 3-4 lb roast. Too much liquid dilutes the flavor and prevents proper browning.
- Rest Before Shredding: Give the pork a solid 10-15 minutes under foil after cooking. My grandmother swore by this, and she was right: it keeps the juices inside where they belong, not all over the cutting board.
Make-Ahead Tips for bone in pork roast instant pot
Overnight Prep
Mix the 1.5 tsp Kosher Salt, 1 tsp Black Pepper, and 1 tbsp Brown Sugar the night before and store in a small container. This dry rub can sit at room temperature, ready to coat your pork when you start cooking. 💡
Morning Sear
If you’re short on time in the evening, sear the pork in the morning and refrigerate it in the Instant Pot with all aromatics and liquids. When ready to cook, just secure the lid and pressure cook as directed.
Partial Cook Method
For even more convenience, pressure cook the roast for only 30 minutes in the morning. Refrigerate it in the cooking liquid, then finish with 15 minutes of pressure cooking when you’re ready to serve.
Liquid Storage
After cooking, store the pork in its juices in an airtight container for up to 3 days. The liquid keeps the meat moist and enhances flavor when reheated. Reheat gently in the Instant Pot on “Sauté” for 5-10 minutes. ❄️
Freezer-Friendly
Shred the cooked pork and portion it with some cooking liquid into freezer bags. It freezes beautifully for up to 3 months. Thaw overnight in the fridge before reheating.
Reheat with Care
To maintain moisture, add ¼ cup Chicken Broth or water when reheating shredded pork in the Instant Pot. Cook on high pressure for 5 minutes, then let the pressure release naturally for best results.

Frequently Asked Questions
Can I use a boneless pork roast instead?
Yes, but bone-in adds more flavor and keeps the meat juicier. For boneless, reduce cooking time to 35 minutes on high pressure to prevent drying out.
Why is searing the pork important?
Searing builds a flavorful crust and enhances the pork’s taste. It also helps render some fat, preventing a greasy texture in the final dish.
What if my pork isn’t tender after cooking?
If it resists shredding, return it to the Instant Pot with extra ½ cup Chicken Broth and cook for another 10-15 minutes on high pressure.
Can I double the recipe?
Not recommended—overfilling the Instant Pot can affect pressure and cooking. For larger batches, cook in two separate batches for best results.
