The bone-in pork shoulder is non-negotiable here—look for cuts with good marbling at your butcher or grocery store's meat counter. Costco or Whole Foods often have excellent options, but any well-stocked supermarket will carry it. The bone adds incredible depth of flavor, so don't substitute boneless. For the celery crown, fresh celery with vibrant green tops makes all the difference—skip the wilted stalks. The fresh herbs (thyme and rosemary) should smell aromatic and bright; if they smell stale, toss them. I always buy extra because they make the dish sing.
No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch, but it won't be identical. Fresh thyme or rosemary unavailable? Dried at one-third the amount gets you close, though fresh is ideal. The apple cider vinegar adds tang—substitute lemon juice if that's what you have. For the crispy topping, panko is essential—it gives that perfect crunch. No panko? Regular breadcrumbs toasted in the oven for 10 minutes work, but they won't be as crisp. The butter in the topping needs to be cold—take it straight from the fridge when mixing.
This roast reheats beautifully—3-4 minutes on high in the Instant Pot with a splash of water. Store leftovers in the fridge for 5-6 days, or freeze for 3 months for those lazy weeknights. The celery crown topping can be made ahead and refrigerated for 2 days before baking. Double the recipe if you're feeding a crowd—Instant Pots handle it easily. The pork gets more tender with each reheat, so plan accordingly.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe when I’m too tired to chop a million veggies—just toss in the celery, onion, and garlic whole, and the Instant Pot does the rest. The aromatics soften perfectly without overpowering the pork, and cleanup is basically just rinsing the pot.
- Deep, Savory Payoff: That bone-in magic? It melts into the meat, turning it impossibly tender while the apple cider vinegar brightens everything up. You get this perfect balance of rich, herby, slightly tangy flavor that makes it taste like you slow-cooked for hours—even though you didn’t.
- Leftovers That Don’t Suck: Between us, most pulled pork leftovers are sad. Not this. The meat shreds so easily, it’s ideal for tacos, sandwiches, or even a quick breakfast hash the next morning. I’ve fed a crowd with this twice and still had enough for lunch.
- Budget-Friendly Crowd-Pleaser: A bone-in pork shoulder is cheaper than boneless cuts, and the flavors stretch across multiple meals without feeling repetitive. Honestly, this is my go-to for game days, potlucks, or when I need to feed my family without breaking the bank. Everyone clears their plate.
Step-by-step instructions for pressure-cooked pork shoulder with celery crown topping
Transform your Instant Pot into a pull-apart pork masterpiece with this foolproof method.
Season and Sear the Pork Shoulder
Start by patting the 4 lb bone-in pork shoulder roast completely dry with paper towels—this ensures maximum crispiness later. In a small bowl, mix together 1.5 tbsp salt, 2 tbsp smoked paprika, 1 tbsp ground black pepper, 0.25 cup fresh thyme, and 0.25 cup fresh rosemary. Rub this seasoning blend all over the pork, pressing firmly so it adheres well, especially in the crevices.
Heat 0.25 cup olive oil in your Instant Pot on the "Sauté" setting over medium-high heat. Once shimmering, add the pork shoulder fat-side down and sear for 5-6 minutes until deeply browned. Flip and sear the other side for another 4-5 minutes. This step builds flavor and creates a barrier that locks in juices during pressure cooking.
Pressure Cook Until Fork-Tender
Add 0.25 cup apple cider vinegar and 0.5 cup brown sugar to the Instant Pot, scraping up any browned bits from the bottom. Pour in 2 cups water (enough to come about halfway up the pork). Place the pork shoulder fat-side up in the pot, then secure the lid and set the valve to "Sealing."
Cook on High Pressure for 90 minutes. When the cooking cycle completes, allow a 10-minute natural release before quick-releasing any remaining pressure. The pork should be fork-tender with a probe sliding in easily—this is your signal that the magic has happened. If not quite there, add 1 cup broth and cook another 15-20 minutes on High Pressure.
Prepare the Celery Crown Topping
While the pork rests, prepare the topping. In a small bowl, combine 0.5 cup panko breadcrumbs, 0.25 cup unsalted butter (cold, cubed), 0.5 cup olive oil, 1 tbsp smoked paprika, and 1 tsp salt. Mix until the butter is evenly distributed and the crumbs look moist but not wet.
Cut 4 whole celery stalks into 1-inch pieces and 1 whole yellow onion into ½-inch slices. In a large skillet, heat 1 tbsp olive oil over medium heat. Add the celery and onion, cooking for 8-10 minutes until softened and lightly caramelized. Stir in the prepared crumb mixture and cook for another 3-4 minutes until golden and crispy. Keep warm while you shred the pork.
Shred and Serve with Crispy Topping
Remove the pork from the Instant Pot and transfer it to a cutting board. Let it rest for 10 minutes, then shred using two forks or a meat claw. The pork should pull apart easily with minimal resistance—this is your confirmation of perfect tenderness.
Return the shredded pork to the Instant Pot and top generously with the crispy celery crown mixture. Serve immediately, letting guests dig into the tender meat and crunchy topping. The contrast of textures and flavors—smoky, sweet, herby, and crispy—makes this dish unforgettable.
Pro Tips For Making Bone In Pork Shoulder Roast Recipe Instant Pot
- SEAR THE BONE FIRST: That bone-in cut needs a quick 3-4 minute sear in a hot skillet before going into the Instant Pot—yes, even if you’re pressed for time. I learned this the hard way when my first batch tasted bland; the Maillard reaction on the bone infuses flavor that slow cooking alone won’t replicate. Use a splash of apple cider vinegar in the pan if you’re worried about sticking.
- CHOP VEGETABLES UNIFORM: Celery, onion, and garlic should all be cut to roughly 1-inch chunks—no tiny dice, no giant hunks. I used to eyeball it, but uneven pieces mean some vegetables turn to mush while others stay crunchy. A sharp knife and a little patience here save you from a watery, unbalanced broth later.
- PRESSURE COOK LOW: Set your Instant Pot to high pressure for 45 minutes, then switch to low pressure for the remaining 30-45 minutes—this prevents the meat from drying out. I was skeptical until I tried it; high pressure gets the meat tender, but low pressure keeps it juicy without overcooking the edges.
- REST IT COVERED: After releasing the pressure, transfer the pork to a cutting board and tent it loosely with foil for 10 minutes—don’t skip this, even if you’re hungry. I’ve sliced into it too soon, and the juices pool on the plate instead of staying in the meat. Let it rest, and every bite will be moist.
Essential equipment for bone in pork shoulder roast recipe instant pot
Instant Pot Essentials
Your Instant Pot is the star here, but you’ll need a few key accessories to pull this off perfectly. First, a meat thermometer (I love the Thermoworks Smoke) is non-negotiable—it ensures your pork hits the sweet spot of 203°F internal temperature without overcooking.
A fork or meat claw for shredding is also essential, and I’ve found that two sturdy forks work best for this tender pork. 🌡️
Celery Crown Tools
For the crispy celery crown topping, a sharp chef’s knife is crucial for clean cuts—celery should be sliced into 1-inch pieces for even cooking. A large skillet (I use my 10-inch Lodge cast iron) gives enough surface area for the celery and onion to caramelize properly.
A wooden spoon helps stir the crispy topping without breaking up the texture. The panko breadcrumbs need to be toasted in the oven for extra crunch, so preheat your oven to 375°F if you’re making a big batch ahead of time.
Budget-Friendly Swaps
Don’t have a meat thermometer? A skewer or long fork works in a pinch—just insert it into the thickest part of the pork to check for doneness. No cast iron skillet? A heavy stainless steel skillet handles the job just fine.
For the crispy topping, regular breadcrumbs toasted in the oven for 10 minutes at 375°F mimic panko’s texture. I’ve also used crushed potato chips for an extra-crispy alternative when I’m in a hurry. The key is keeping everything lightly oiled for that perfect crunch. 💡
Grandmother’s Wisdom
My grandmother always said, “The best tools are the ones you already own.” She’d use a rolling pin to crush garlic cloves instead of buying pre-minced, and a wooden spoon to stir everything—no fancy gadgets needed.
For this recipe, her heavy-bottomed pot (the one she inherited from her mother) worked perfectly for the celery crown topping. If you’re just starting out, don’t stress about buying new tools—just focus on the olive oil, fresh herbs, and patience—those are what make this dish shine. 🍳
Safety First
Pressure cooking is safe, but a few precautions make all the difference. Always double-check your Instant Pot’s gasket is intact and the valve is set to “Sealing” before starting. Never quick-release the pressure unless absolutely necessary—your pork needs that 10-minute natural release to stay juicy.
I also recommend lining the Instant Pot with parchment paper (cut to fit) for easy cleanup after shredding. And remember: hot steam = caution—use oven mitts when handling the pot after cooking. 🔥
Make-Ahead Gear
Prepping ahead saves time on busy days. Store the shredded pork in an airtight container with some of its juices—it keeps well in the fridge for 5-6 days or freezes beautifully for 3 months.
The celery crown topping can be made a day ahead and reheated in the oven at 350°F for 5-7 minutes to restore crispiness. I like using glass containers for leftovers because they reheat more evenly.
If you’re feeding a crowd, double the recipe—the Instant Pot handles it easily, and you’ll have plenty for seconds! 📅

Frequently asked questions
Can I use boneless pork shoulder instead of bone-in?
I don't recommend it for this recipe—the bone adds incredible flavor and helps tenderize the meat during pressure cooking. If you must use boneless, reduce the cooking time by 10-15 minutes (start with 75 minutes instead of 90 minutes) since it cooks faster without the bone's insulating effect. The texture will be slightly different but still delicious.
What if my pork shoulder isn't tender after 90 minutes?
Add 1 cup broth or water to the Instant Pot, then cook for another 15-20 minutes on High Pressure. Most 4 lb cuts will be tender at 203°F internal temperature, but thicker or tougher cuts may need extra time. Never exceed 120 minutes total at high pressure to avoid overcooking.
Can I make the crispy celery crown ahead of time?
Prepare the topping up to 2 days ahead and store it in an airtight container at room temperature. Reheat in a 350°F oven for 5-7 minutes to restore crispiness before serving. For extra crunch, sprinkle with 1 tsp smoked paprika after reheating.
What sides pair best with this pork shoulder?
Classic choices include mashed potatoes, cornbread, or roasted sweet potatoes—all of which soak up the rich pork juices beautifully. For a lighter option, try a simple green salad with apple cider vinaigrette (using the same vinegar from the recipe). The crispy celery crown adds enough richness that you don't need heavy sides.
Why does my Instant Pot say "Burn" after cooking?
This happens when food bits stick to the bottom during searing. Always scrape up browned bits with a wooden spoon before adding liquid. For stubborn residues, add 1 cup water, secure the lid, and run a 1-minute High Pressure cycle to steam-clean. Wipe the pot with a damp paper towel before your next use.
