Instant Pot Pork Tenderloin with Pan Sauce

Share this post

If I told you that you could cook a pork tenderloin in your Instant Pot in 2 minutes, would you believe me? Well, I don’t joke about food so trust me…it’s possible!

It’s finally warming up where I live! I think most of the midwest was wondering if Spring would ever arrive! Spring and summer are my favorite seasons so I am more than welcome the sunshine and outside time!

When the weather is nice, my family and I like to spend a lot of time together playing outside, adventuring around town, and making memories. I like to have easy, quick, go-to recipes for those nights because let’s face it, moms don’t get a break when it comes to fixing supper! For some reason, everyone always wants to eat! 😉

I got an Instant Pot for Christmas and it has become one of my favorite kitchen tools! I’m always amazed at how fast it gets a meal did that would otherwise take hours! My mind is blown every time! It never gets old, ha!

I’ve been experimenting (and researching) Instant Pot recipes quite a bit, especially as summer approaches. Family dinner time is really important to me. Family happens around the table. That’s where conversation flows, time slows down for a few minutes, and everyone is in good spirits. (Unless maybe you have a three-nager like me who refuses to eat real food but that’s a topic for another day.) Having recipes like this one makes it possible to enjoy our life AND feed your family a nutritious meal!

So, are you still skeptical about cooking WHOLE pork tenderloin in an Instant Pot in 2 minutes? I was too. But then I tried it and I was a believer!

Pork tenderloin is one of my favorite cuts of pork. It’s naturally flavorful, easy to make, and the possibilities are endless. Pork tends to be overlooked in the keto world because it’s so lean but it shouldn’t be! You don’t need fancy steaks every night to “be keto”. Bacon, pork belly, chops, loins, roasts…they’re all keto friendly!

My sugar free teriyaki sauce would be absolutely delish on a pork tenderloin too!

Pork is also really affordable meat for a ketogenic diet! Y’all know I’m all about budgeting and saving money so tenderloins tend to be a go-to for me! I grabbed a pack of 4 2-lb tenderloins at Costco for less than $20! That’s roughly $5 per meal for a family of four! Score!!

When you’re making lean meats like pork, the key is to add your fat in sauces, marinades, and side dishes. I served these sweet and savory pork tenderloin medallions over a cauliflower mash with a side salad. It was the perfect keto meal and all ready in about half an hour!

You can see how I make cauliflower mash in this post!

A Few Notes About This Recipe:

1. Be sure to get a pork TENDERLOIN and not a pork loin. A pork loin looks more like a roast and is not the same.

2. Make sure to marinate the meat for at least 30 minutes. The longer it soaks, the more flavor it will have though. If you can get it in the fridge in the morning, it’ll be much more flavorful by dinner time.

3. There is no substitution for Sukrin Gold. It is the only brown sugar substitute I know of that is keto-friendly (i.e. it doesn’t actually have sugar). You can get it on Amazon for about $10. It is a staple in my pantry nowadays and I use it in a TON of my recipes.

4. You can use coconut oil or olive oil instead of avocado oil for the searing.

5. Do NOT get nervous and kick up the cooking time. For a juicy and tender pork tenderloin, this method WILL work! Make sure to give it the rest time in the IP before opening AND the rest time on the platter while you make the sauce. Pork is fully cooked at 145 degrees Fahrenheit.

6. If you want to make the pan sauce on the stove, follow the same steps as the recipe. You can add a little more Sukrin Gold if you want the sauce sweeter.

7. I cut my medallions in about 1.5″ pieces but the size will vary depending on your size tenderloin. We had plenty of leftovers. I served the adults 2-3 pieces and the kids 1 piece each.

Cook Time 15 mins
Total Time 15 mins
Servings 6


  • 2 or 2.5 lb pork tenderloin
  • 1 tbsp dijon mustard
  • 1/2 tbsp avocado oil
  • 1 garlic clove
  • 2 tbsp Sukrin Gold brown sugar substitute
  • 1 tbsp fresh parsley minced
  • 1/4 cup water for IP
  • 1/4 tsp xanthan gum

  • Pat pork tenderloin dry with a paper towel.
  • Brush Dijon mustard all over.
  • Mix garlic clove, Sukrin Gold, and parsley in a dish and rub all over pork tenderloin.
  • Refrigerate for at least 30 minutes, up to overnight.
  • Turn the IP on to SAUTE setting and add avocado oil. When the IP reaches temperature, sear the outside of the tenderloin on all sides. This should take no more than 5 minutes.
  • Add water to IP and cook on LOW pressure for 5 minutes. Let pressure NATURAL RELEASE for 10 minutes before opening the steam vent. If your pork tenderloin is more than 2lbs, you may want to let it sit in NR for an extra 1-2 minutes before releasing.
  • Remove tenderloin to a platter and cover with foil. Let rest for 10 minutes while you make the sauce.
  • Turn IP to SAUTE setting. When the juices start bubbling, add ACV and xanthan gum. Whisk continuously until the sauce is thickened.

The actual recipe is a bit confusing. It says: Add water to IP and cook on LOW pressure for 5 minutes. Let pressure NATURAL RELEASE for 10 minutes before opening steam vent. If your pork tenderloin is more than 2lbs, you may want to let it sit in NR for an extra 1-2 minutes before releasing.. The lead paragraph says 2 minutes but does not say at what pressure (high or low) and type of pressure release. Immediate or time for pressure release. I found another recipe (Amy & Jacky) that says Pressure Cook at High Pressure for 0 minute, then 15 minutes Natural Release. I don't mind experimenting but figured I'd ask anyway. Thanks,

Hi Rich- you're right, it is kind of confusing as written (it's a very old post). I will update the recipe card to match the instructions in my cookbook (it's in there too). Thanks for bringing it to my attention!
