Instant Pot Pork Tenderloin Recipe: Juicy, Fall-Apart Perfection in 45 Minutes

Achieving fall-apart tender pork tenderloin in under an hour is entirely possible with the Instant Pot. This method delivers juicy, perfectly cooked meat every time, without the guesswork of traditional roasting or grilling. The pressure cooker locks in moisture while breaking down fibers for that ideal melt-in-your-mouth texture.

The process is streamlined yet precise: a quick sear for flavor development, followed by high-pressure cooking that transforms the tenderloin in just 25 minutes. No babysitting required—the Instant Pot handles the work while you prepare sides. The result is restaurant-quality pork with minimal effort and maximum reliability.

Ingredients for Instant Pot Pork Tenderloin

Everything you need for that perfect fall-apart pork—simple seasonings, quick sear, and pressure cooker magic.

The pork tenderloin is the star here—look for 1.5 lb pieces with minimal silver skin (already trimmed saves time). I grab mine from Costco or Whole Foods when it’s on sale and freeze extras. The kosher salt matters: Diamond Crystal gives the best texture without over-salting. Freshly ground black pepper makes a difference (those pre-ground cans lose potency fast). Don’t skip the apple cider vinegar—it cuts through the richness and keeps the meat tender (white wine vinegar works too).

Out of garlic powder? Fresh minced garlic at double the amount works, but add it after searing so it doesn’t burn. No Dijon? Whole grain mustard adds texture, or yellow mustard in a pinch. The chicken broth can be swapped for vegetable broth if that’s what you’ve got. For extra flavor, deglaze with half broth, half dry white wine. Butter haters can finish with olive oil instead—just drizzle it over after cooking.

This keeps beautifully—4 days in the fridge, 3 months frozen. Slice before storing for easy reheating. The cooked pork soaks up flavors even more overnight, so leftovers make killer sandwiches. I portion mine into meal-prep containers with a splash of broth to keep it moist. Pro tip: save the cooking liquid for gravy or soups (it’s liquid gold).

Step-by-Step Instructions for Instant Pot Pork Tenderloin

Here’s the foolproof method for perfectly tender pork every time—no stress, just delicious results.

Step 1: Season and Sear the Tenderloin

Pat the 1.5 lb pork tenderloin completely dry with paper towels. This ensures a proper sear rather than steaming. Combine the 1.5 tsp kosher salt, 1 tsp freshly ground black pepper, 1 tsp garlic powder, 1 tsp onion powder, and 1 tsp dried thyme in a small bowl. Rub this mixture all over the pork, pressing gently so it adheres.

Set your Instant Pot to “Sauté” mode and add 1 tbsp olive oil. When the oil shimmers, add the pork and sear for 2-3 minutes per side until golden brown. You’re not cooking it through—just building flavor. Transfer the pork to a plate and set aside.

Step 2: Deglaze and Build the Cooking Liquid

Pour the 0.5 cup chicken broth into the Instant Pot, using a wooden spoon to scrape up all those delicious browned bits from the bottom. This step is crucial—those fond bits are packed with flavor. Add the 1 tbsp apple cider vinegar and 1 tbsp Dijon mustard, stirring to combine.

Return the seared pork to the pot along with any accumulated juices. The liquid should come about halfway up the pork. If you’re using low-sodium broth, this is your chance to adjust seasoning—taste the liquid and add a pinch more salt if needed.

Step 3: Pressure Cook to Perfection

Secure the lid and set the valve to “Sealing.” Cook on High Pressure for 8 minutes. For a 1.5 lb tenderloin, this timing ensures juicy, tender meat without drying out. The Instant Pot will take about 10 minutes to come to pressure before the cooking time begins.

When the cooking cycle completes, let the pressure release naturally for 10 minutes, then carefully switch the valve to “Venting” to release any remaining pressure. This gradual release prevents the pork from seizing up and becoming tough.

Step 4: Finish with Butter and Rest

Transfer the pork to a cutting board and tent loosely with foil. Switch the Instant Pot back to “Sauté” mode and add the 2 tbsp unsalted butter, stirring until melted into the cooking liquid. This creates a simple pan sauce that’s rich and flavorful.

Let the pork rest for 5-10 minutes before slicing. This resting period allows the juices to redistribute throughout the meat. If you skip this, all those delicious juices will end up on your cutting board instead of in your pork.

Step 5: Slice and Serve with Pan Sauce

Slice the pork against the grain into ½-inch thick pieces. The meat should be tender enough to cut with minimal resistance. Arrange the slices on a platter and spoon the buttery pan sauce over the top.

Garnish with the 2 tbsp fresh parsley for a bright, fresh contrast to the rich pork. The parsley isn’t just for looks—it adds a necessary freshness that balances the dish. Serve immediately while everything is hot and at its most flavorful.

Essential Equipment for Great Instant Pot Pork Tenderloin

Instant Pot Model

The 6-quart Instant Pot Duo is my go-to for this recipe—it’s the perfect size for a 1.5 lb tenderloin with room for searing and pressure cooking. I’ve tested this in both the Duo Nova and Ultra models too, and they all deliver consistent results. The key is using a model with reliable pressure control. 🔥

Wooden Spoon

Don’t underestimate this simple tool! A sturdy wooden spoon is essential for deglazing the pot after searing. I use mine to scrape up every browned bit from the bottom—those fond bits are pure flavor gold. Look for one with a flat edge that can really get into the corners of your Instant Pot.

Digital Thermometer

While the Instant Pot does a great job, I always double-check with my ThermoWorks Thermapen. Pork tenderloin is best at 145°F internal temperature, and this instant-read thermometer gives me peace of mind. Even with pressure cooking, it’s good to verify doneness before serving.

Tongs with Silicone Tips

These are my secret weapon for handling the tenderloin. The silicone-tipped tongs let me flip the pork during searing without piercing it, which keeps all those juices inside where they belong. I prefer the OXO Good Grips version—they’re sturdy and heat-resistant up to 600°F.

Fat Separator

If you want to make the pan sauce extra rich, a fat separator is handy. After cooking, I pour the liquid into my separator to remove excess fat before adding the butter. This step isn’t mandatory but creates a cleaner, more refined sauce. The Norpro 4-Cup model works perfectly for this recipe’s yield.

Cutting Board with Juice Groove

A good wooden cutting board with a juice groove is worth its weight in gold. When resting the pork, those grooves catch all the precious juices that would otherwise spill. I use my John Boos maple board—it’s durable and gentle on knives. The groove design prevents messy countertops while keeping the meat moist. ✨
