Ingredients for boneless pork loin instant pot
Pantry staples plus a few fresh herbs transform simple pork into restaurant-worthy perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin 🐖 | 1 ½ lb | Center-cut for even cooking |
| Garlic Cloves 🧄 | 6 cloves | Minced for even distribution |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme Leaves 🌿 | ¼ cup | Packed, stems removed |
| Brown Sugar 🍯 | 2 tbsp | Light or dark variety |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | 1 tsp | Freshly ground preferred |
| Apple Cider Vinegar 🍎 | 1 tbsp | For tenderizing |
| Low-Sodium Chicken Broth 💧 | ½ cup | For moisture during cooking |
| Honey 🍯 | 1 tbsp | For glaze finish (optional) |
The pork loin is the star—center-cut for even cooking and minimal fat. Grab one from the butcher counter if you can; they'll often trim it to your desired size. Look for good marbling, but boneless means you won't have to worry about trimming. Fresh herbs are non-negotiable here—Trader Joe's sells pre-chopped rosemary and thyme in little jars, which saves time. If you're using dried, cut the amount in half, but honestly, fresh makes all the difference. The brown sugar isn't just for sweetness; it helps caramelize the crust during pressure cooking.
No fresh rosemary? Dried at half the amount works, but it won't have that same piney aroma. Short on apple cider vinegar? Lemon juice is a perfect swap, though it'll add a slight tang. The honey glaze is optional but adds that restaurant-quality shine—Manuka honey if you want to splurge, regular works fine too. For the broth, low-sodium is key so you don't over-salt the pork. If you're using a bouillon cube, Knorr or Homemade Style are the most neutral options. The olive oil should be extra-virgin—California brands like Corto or Colavita are my go-tos for this kind of cooking.
Pork loin keeps best wrapped in parchment paper in the fridge for 3-4 days—use it within that window for peak tenderness. The seasoning mix? Make it ahead and store in an airtight container for up to 2 weeks. Once cooked, slice against the grain and serve immediately or reheat in the Instant Pot on high for 5 minutes with a splash of broth. Leftovers reheat beautifully, but they're so good fresh you'll likely eat it all right away.

Step-by-step instructions for pressure-cooked pork loin
Here's how to transform a simple pork loin into a melt-in-your-mouth masterpiece using your Instant Pot.
Prep the Pork and Herbs for Maximum Flavor
Pat the 1.5 lb boneless pork loin dry with paper towels—this is crucial for that perfect sear later. Place it on a cutting board and make shallow slashes about ¼-inch deep in a crosshatch pattern on all sides. This helps the marinade penetrate deeper and keeps the meat tender.
In a small bowl, combine the 6 cloves minced garlic, 0.25 cup chopped fresh rosemary, 0.25 cup packed fresh thyme leaves, 2 tbsp brown sugar, 1.5 tsp salt, 1 tsp black pepper, and 1 tbsp apple cider vinegar. Rub this mixture all over the pork, pressing it into the slashes. Let it sit at room temperature for 15 minutes while you prep the Instant Pot—this ensures even cooking and maximum flavor infusion.
Sear the Pork for Deep Flavor
Set your Instant Pot to "Sauté" mode and let it heat for 2 minutes. Add the 2 tbsp olive oil and carefully place the pork loin in the pot, fat-side down. Sear for 3-4 minutes until a deep golden crust forms—this is your flavor foundation. Flip the pork and sear the other side for another 3-4 minutes until evenly browned.
Here's the thing—don't rush this step. You want that beautiful crust that holds all the herbs and spices. If the oil starts smoking before the pork browns, reduce the heat slightly and give it more time. The goal is golden brown color, not charred edges.
Pressure Cook to Perfect Tenderness
Pour in the 0.5 cup low-sodium chicken broth around the pork, being careful not to submerge it completely. Secure the lid, set the valve to "Sealing," and cook on High Pressure for 25 minutes. This timing gives you that ideal balance between tender meat and juicy perfection.
Resist the urge to peek or open the lid during cooking—releasing pressure early can lead to dry meat. When the timer goes off, let the pressure release naturally for 10 minutes before quick-releasing the remaining pressure. This gradual release keeps all those juices locked inside where they belong.
Glaze and Rest for Restaurant-Quality Results
Remove the pork from the pot and transfer it to a cutting board. In the Instant Pot, increase the heat to "Sauté" again and add the 1 tbsp honey. Let it bubble for 1-2 minutes until it turns into a glossy glaze. Brush this honey mixture all over the pork, letting it caramelize slightly for that beautiful finish.
Let the pork rest for 10 minutes before slicing—this is non-negotiable. During this time, the juices redistribute throughout the meat, ensuring each slice is moist and flavorful. Cut it against the grain into ½-inch thick slices and serve immediately with your favorite sides.
Serve with Confidence
Each slice should be tender enough to pull apart with minimal resistance, with a perfect balance of herby, slightly sweet flavors from the glaze. The crust should still hold its shape slightly, providing texture contrast to the melt-in-your-mouth interior.
For best results, serve with roasted vegetables or a fresh salad to complement the rich pork. The leftovers actually improve the next day—just reheat with a splash of broth to maintain moisture. This method delivers restaurant-quality pork loin with minimal effort, and it's a game-changer for weeknight dinners.
Pro Tips For Making Boneless Pork Loin Instant Pot
- SEAR FIRST, THEN SAUCE: I learned this the hard way—skipping the sear means flavor gets trapped in the Instant Pot instead of building layers. Hit the pork loin with a hot pan (2 minutes per side) before adding anything else—garlic, herbs, or brown sugar. The caramelized crust stays put, even under pressure.
- CHOP HERBS COARSELY: Fresh rosemary and thyme lose their punch when they turn to mush. Roughly chop the stems (no need to remove them entirely) and scatter them over the pork after searing. They’ll infuse flavor without dissolving into the sauce—just fish them out before serving if you’re picky.
- USE A MEAT THERMOMETER: That 160°F high-pressure reading isn’t always accurate for pork loin. The center should hit 145°F—any hotter and it dries out faster than a summer bonfire. I used to guess and ended up with rubbery slices. Now I wait for the thermometer, even if the pot says “done.”
- BROWN SUGAR FIRST: Don’t toss it in raw—caramelize 1 tablespoon in the Instant Pot (on sauté mode) for 2 minutes until it’s amber and fragrant. This cuts the bitter edge and adds depth the recipe won’t have otherwise. (Yes, even if you’re in a hurry—it’s worth the 5 minutes.)
Common mistakes when making this recipe
Overcooking Time
Pressure cooking pork loin for more than 25 minutes on high pressure turns tender meat into tough, dry rubber. I’ve seen this happen when people double-check timers or get distracted.
The 25-minute mark is perfect for a 1.5 lb cut—any longer and the collagen breaks down too much, leaving you with stringy results. Set a timer and walk away. 🕒
Skipping Sear
Skipping the sear is the fastest way to bland pork. That golden crust isn’t just for looks—it traps all those herby, garlicky flavors from your marinade. If you’re in a rush, at least do a 2-minute sear per side on medium-high heat.
No sear? Your pork will taste like it’s missing something, no matter how long you pressure cook it.
Ignoring Rest Time
Cutting into pork immediately after cooking sends all those juices pooling on your plate instead of staying in the meat. The 10-minute rest is your secret weapon for juicy slices.
I’ve seen people slice right after quick-releasing and end up with dry, sad-looking pork. Trust me—this step makes the difference between good and great.
Using Wrong Broth
Regular chicken broth with high sodium content will turn your perfectly seasoned pork into a salty disappointment. Always use low-sodium broth—I recommend Swanson or Pacific Foods brands.
If you’re using bouillon cubes, stick to 1 cube per cup of water to avoid over-salting. The broth just needs to add moisture, not dominate the flavor.
Natural Release Only
While natural release helps with juiciness, doing it exclusively can sometimes leave the pork slightly undercooked in the center. The trick is 10 minutes natural release followed by a quick release.
This gives you the best of both worlds—juicy meat without risking undercooking. Always check the internal temperature with a meat thermometer; it should reach 145°F.
Uneven Seasoning
Rubbing seasoning only on the outside means flavorless interior slices. Make those ¼-inch deep slashes in a crosshatch pattern and press the marinade into every crevice. I’ve seen people skip this step and end up with bland center slices that taste like they missed the flavor party entirely.
Take the extra 5 minutes** to do it right—your taste buds will thank you. 💛

Frequently asked questions
Can I use frozen boneless pork loin in the Instant Pot?
No, frozen pork loin should never go straight into the Instant Pot. Always thaw it first in the refrigerator for 24 hours or use the defrost setting on your microwave. Frozen meat can cause uneven cooking and may not reach a safe internal temperature. The 145°F safety threshold is critical for pork—never compromise on this step!
What if my pork loin is thicker or thinner than 1.5 lbs?
Adjust cooking time by 2-3 minutes per pound for thicker cuts (up to 2 lbs) or reduce by 1-2 minutes for thinner cuts (under 1 lb). For example, a 2 lb loin would need 28-30 minutes on high pressure. Always use a meat thermometer to confirm 145°F internal temp—this is more reliable than time alone.
Can I make this recipe without fresh herbs?
Yes, but the flavor will be less vibrant. Use 1 tsp dried rosemary and 1 tsp dried thyme instead of fresh, and increase the garlic to 8 cloves. The brown sugar and honey will still give sweetness, but fresh herbs add that aromatic depth that's hard to replicate. If you're short on time, Trader Joe's sells pre-chopped herb blends that work in a pinch.
How do I prevent the pork from sticking to the Instant Pot?
Always pat the pork completely dry before searing and use 2 tbsp olive oil generously on the bottom of the pot. For extra insurance, place a silicon mat or parchment paper in the pot before adding the pork. The high heat during searing can cause sticking if the surface isn't properly oiled. A little extra prep goes a long way!
What are the best side dishes to serve with this pork?
This tender pork pairs beautifully with roasted Brussels sprouts (tossed in olive oil and balsamic), garlic mashed potatoes, or a crisp apple salad with walnuts and goat cheese. For a lighter option, try sautéed green beans with lemon zest. The herby flavors in the pork complement earthy, creamy, or slightly acidic sides perfectly.
