This bone-in pork loin Instant Pot recipe transforms tough cuts into melt-in-your-mouth perfection with a crispy celery crown topping that adds restaurant-quality texture. The secret lies in proper pressure cooking techniques—high heat, precise timing, and a slow release—that lock in juices while rendering fat for maximum flavor.
I’ve perfected this method after years of testing, ensuring tender meat with a golden, caramelized crust that holds up to every bite.
The process begins with a quick sear in the Instant Pot to develop deep, savory notes before pressure cooking, which breaks down collagen for fork-tender results.
Aromatics like garlic and thyme infuse the meat naturally, while the celery crown—made from crispy celery stalks—adds a satisfying crunch that contrasts beautifully with the tender pork. This method cuts cooking time by half compared to traditional oven roasting, without sacrificing flavor or texture.
What you’ll achieve is a crispy, golden-brown pork loin with a juicy, pink center and a celery crown that stays crisp even after serving. The fat cap renders perfectly, basting the meat as it cooks, while the celery adds a bright, herbal note that balances the richness.
Serve with roasted potatoes or a fresh green salad to complete the meal—this dish is elegant enough for dinner parties but simple enough for weeknights.
For best results, let the pork rest before slicing to retain juices, and don’t skip the celery crown—it’s the game-changer that elevates this dish from ordinary to extraordinary.
The recipe scales easily, making it ideal for feeding a crowd or meal prepping ahead. Let’s get started with a method that delivers professional-quality results at home.
Ingredients for bone in pork loin instant pot
The key ingredients for restaurant-quality Instant Pot pork loin with crispy celery crown.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Loin 🥩 | 2 lb | 2-inch thick cut with fat cap |
| All-Purpose Flour 🌾 | ¼ cup | For dredging celery crown |
| Celery Stalks 🧅 | 6 whole | Thick, crisp stalks only |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for searing |
| Yellow Onion 🧅 | 1 whole | Medium, sliced into wedges |
| Garlic Cloves 🧄 | 6 cloves | Smashed for aromatic depth |
| Fresh Thyme 🌿 | ½ oz | Or 1 tbsp dried thyme |
| Salt 🧂 | 1 ½ tsp | Kosher salt, coarse grind |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked peppercorns |
| Olive Oil 🫒 | 1 tbsp | For Instant Pot sear |
| Low-Sodium Chicken Broth 💧 | ½ cup | For pressure cooking liquid |
| Honey 🍯 | 1 tbsp | For glaze finish (optional) |
| Cornstarch 🌾 | 1 tbsp | For crispy celery crown |
The pork loin is non-negotiable here—look for a 2-inch thick cut with a fat cap at your butcher or Costco bulk section. Thicker cuts render more fat for basting, while the fat cap creates that golden crust. If buying pre-cut, check for marbling (white fat streaks) which ensures juiciness. For the celery crown, thick stalks (about 1-inch diameter) are essential—they crisp better than thin ones. Trader Joe's often carries perfect celery for this, or check the produce section for stalks with vibrant green tops. Fresh thyme is ideal, but dried works at one-third the amount if you're in a pinch.
No kosher salt? Diamond Crystal kosher salt is the gold standard, but sea salt works fine in a 1:1 ratio. For the celery crown, cornstarch is the secret to crispiness—don't skip it. The honey glaze is optional but adds a beautiful finish; local honey has more flavor if you want to splurge. If you're short on time, pre-sliced onions from the grocery store work, but whole onions add more depth when caramelized. The broth can be low-sodium vegetable broth if you prefer, but chicken broth pairs perfectly with pork. For the butter, European-style (like Plugrá) has higher fat content for better searing.
Store leftover pork in an airtight container for up to 4 days—it reheats beautifully. The celery crown loses crispness after 2 days, so make it fresh if possible. For meal prep, freeze the pork only (without celery crown) for up to 3 months. The fat cap keeps it moist during freezing. If you're doubling the recipe for a crowd, increase the celery crown proportionally—it's the star of the dish. Let the pork rest 10 minutes before slicing to retain juices, and don't skip the honey glaze if you want that restaurant-quality finish.

Step-by-step instructions for bone-in pork loin with celery crown
Pressure cooking delivers tender pork while the crispy celery crown adds texture and flavor.
Prepare the Pork and Celery Crown
Pat the 2 lb bone-in pork loin dry with paper towels—this ensures a better sear later. Season both sides generously with 1.5 tsp salt and 0.5 tsp ground black pepper. Set aside at room temperature for 30 minutes while you prep the celery crown.
For the celery crown, cut the 6 whole celery stalks crosswise into ½-inch thick slices. In a bowl, whisk together 0.25 cup all-purpose flour, 1 tbsp cornstarch, 1 tsp salt, and 0.25 tsp black pepper. Toss the celery slices in this mixture until evenly coated. Spread them on a baking sheet and set aside.
Sear the Pork and Celery in the Instant Pot
Set your Instant Pot to "Sauté" mode and add 1 tbsp olive oil. Once hot, place the pork loin fat-side down and sear for 3-4 minutes until golden brown. Flip and sear the other side for 2-3 minutes. Remove the pork and set aside.
In the same pot, add 0.5 cup unsalted butter and melt over medium heat. Add the 1 whole yellow onion, sliced into wedges, and 6 smashed garlic cloves. Cook for 3-4 minutes until softened. Return the pork to the pot, fat-side up, and pour in 0.5 cup low-sodium chicken broth. Stir to deglaze any browned bits.
Pressure Cook the Pork
Secure the lid on your Instant Pot and set the valve to "Sealing." Cook on High Pressure for 45 minutes. Once done, allow a natural release for 15 minutes, then quick-release any remaining pressure. The internal temperature should reach 195°F—this ensures fork-tender meat.
While the pork rests, heat a skillet over medium-high heat and add the celery crown. Cook for 5-6 minutes, stirring occasionally, until golden brown and crispy. Remove from heat and set aside.
Finish and Serve
Carefully remove the pork from the pot and transfer it to a cutting board. Let it rest for 10 minutes before slicing. The juices will redistribute, keeping every bite moist.
For a glaze, stir 1 tbsp honey into the cooking liquid in the Instant Pot. Simmer for 2-3 minutes until slightly thickened. Drizzle this glaze over the sliced pork and top with the crispy celery crown. Serve immediately with roasted vegetables or mashed potatoes.
Pro Tips For Making Bone In Pork Loin Instant Pot
- SEAR THE PORK FIRST: I learned this the hard way—skipping the sear means flavorless pork. Use the Instant Pot’s sauté function to brown the bone-in loin on all sides before adding liquid. The crust locks in juices and adds depth that no amount of broth can replace.
- TRIM EXCESS FAT FROM THE BONE: That pork loin bone can bleed fat into your broth, making it greasy. Wipe it down with paper towels after searing, then use kitchen shears to snip away any large fat deposits near the bone. Your finished dish will thank you—no one wants a soggy, greasy sauce.
- DON’T SKIP THE FLOUR SLURRY: The flour isn’t just for thickening—it’s what builds the sauce’s body. Whisk it with cold water (about 2 tablespoons flour to ¼ cup water) and stir it into the hot Instant Pot after pressure cooking, not before. Let it simmer for 2–3 minutes to cook out the raw taste, or you’ll end up with a mealy, gluey mess.
- USE COLD BUTTER FOR FINISHING: Tossing in cold butter at the end isn’t just for richness—it cools the sauce slightly, giving you time to adjust seasoning. Cut a 2-tablespoon pat into small cubes and swirl it in while the pork rests. It melts faster and makes the sauce silky instead of greasy. (Yes, even if you’re impatient like me.)
Pro cooking tips for this dish
Sear for Depth
That initial sear in the Instant Pot isn't just for looks—it builds Maillard reaction flavors that transform bland pork into something rich and complex. Use medium-high heat and let the fat cap render slowly for 3-4 minutes per side.
If your Instant Pot's sear function isn't strong enough, try a separate cast-iron skillet first for deeper browning. 🔥
Pressure Time Precision
The 45-minute high-pressure cook is non-negotiable for bone-in pork—any less risks dry meat. Use a meat thermometer to verify 195°F internal temp (the bone helps conduct heat evenly).
For thicker cuts (over 2.5 lbs), add 5-10 minutes to the cook time. Never skip the 15-minute natural release—this prevents steam explosions when opening.
Celery Crown Secrets
The celery crown's crispiness comes from double-coating: first in flour, then in cornstarch. Use a wire cooling rack instead of paper towels to drain excess moisture before frying—this ensures maximum crisp.
For extra crunch, add ½ tsp smoked paprika to the flour mix. If your celery isn't crispy after 5 minutes, reduce heat to medium-low and cook longer—rushing burns it.
Resting Matters
Skipping the 10-minute rest means juices will pool on your cutting board instead of in the meat. For extra insurance, tent the pork loosely with foil while resting. Pro tip: Use this time to make your honey glaze—simmering it while the pork rests infuses it with porky depth.
The glaze should coat the back of a spoon but remain pourable. 💫
Broth Swaps
Chicken broth is classic, but pork broth adds deeper umami. For a smoky twist, replace ¼ cup broth with liquid smoke (just ½ tsp). Avoid heavy cream-based broths—they can make the pork greasy.
If using vegetable broth, add ½ tsp soy sauce to balance flavors. Always deglaze with 1 tbsp apple cider vinegar after searing to cut through any bitterness.
Instant Pot Upgrades
Upgrade your sear game with a stainless steel trivet—it elevates the pork above liquid for better browning. For the celery crown, try an air fryer at 375°F for 8 minutes if you want even crispier results. If your Instant Pot lacks a sear function, use the "Sauté More" trick**: keep the pork in the pot and add 2 tbsp water to create steam while searing. This prevents burning while maintaining heat.

Frequently asked questions
Why does this recipe use bone-in pork loin instead of boneless?
The bone adds incredible flavor and moisture during cooking—it helps render fat that bastes the meat while cooking. Plus, the bone conducts heat evenly, ensuring the pork reaches 195°F without drying out. The crispy celery crown topping also pairs beautifully with the rich, savory notes from the bone.
Can I make this recipe without an Instant Pot?
Yes! For oven cooking, sear the pork in a skillet, then roast at 325°F for 1.5-2 hours until it reaches 195°F internally. Skip the pressure cooking step but follow the same celery crown method. The honey glaze works great as a finishing touch too. For stovetop, use a Dutch oven with medium-low heat for 1.5 hours covered.
How do I know when the pork is done without a meat thermometer?
Press the thickest part of the pork—if it feels very tender and the juices run clear (not pink), it's done. For bone-in pork, the 15-minute natural release after pressure cooking ensures it reaches 195°F safely. If you're unsure, let it cook 5 extra minutes and test again. The celery crown should be golden brown and crispy by then too.
What if my celery crown isn't crispy?
Double-check your coating—celery needs both flour and cornstarch for maximum crisp. Use a wire rack to drain excess moisture before frying, and cook on medium heat for 5-6 minutes. If it's still soft, try adding ½ tsp baking powder to the flour mix for extra lift. For extra crunch, cook the celery in small batches to avoid overcrowding.
Can I make this ahead of time for meal prep?
Cook the pork up to 2 days ahead and store it in an airtight container. Reheat gently in the Instant Pot on "Sauté" mode with 2 tbsp broth until warmed through. The celery crown is best made fresh, but you can reheat it in a 350°F oven for 5-7 minutes to restore some crisp. The honey glaze should be added fresh for best flavor.
