Instant Pot Keto Pork Tenderloin

Share this post

Need a keto-friendly, affordable meal in 30 minutes or less? This Instant Pot Pork Tenderloin with Pan Sauce is ready in only two minutes and perfect for weeknights or for meal prepping.

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.

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 finally — if only briefly — present. When recipes call for a ton of prep work and cook time, it takes away from the time you have with the people you love.

Having recipes like keto-friendly Instant Pot Pork Tenderloin with Pan Sauce makes it possible to have a nutritious meal without sacrificing family time.

Why You Can’t Use Pork Loin For This Recipe

While pork loin is technically the more keto-friendly cut of pork, you still need to use pork tenderloin to follow this recipe. I promise you, they’re not the same.

Pork loin is a thicker cut of meat, more like a roast, making it incredibly tricky to cook in an Instant Pot. It takes longer to cook, and the meat can get very tough very fast when it’s overcooked. Meanwhile, since pork tenderloin is a thinner, leaner cut of meat, it will cook quickly and evenly, and still remain tender and juicy.

Ingredients

  • 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
  • 1/2 tsp apple cider vinegar

Instructions

  1. Pat pork tenderloin dry with a paper towel.
  2. Brush Dijon mustard all over.
  3. Mix garlic clove, Sukrin Gold, and parsley in a dish and rub all over pork tenderloin.
  4. Refrigerate for at least 30 minutes, up to overnight.
  5. 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.
  6. 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.
  7. Remove tenderloin to a platter and cover with foil. Let rest for 10 minutes while you make the sauce.
  8. Turn IP to SAUTE setting. When the juices start bubbling, add ACV and xanthan gum. Whisk continuously until the sauce is thickened.
  9. Slice tenderloin into equal-sized medallions. Pour sauce over medallions and serve.

Top Tips to Make Pot Pork Tenderloin with Pan Sauce:

Start marinating your pork tenderloin at least 30 minutes before you want to start cooking. The longer you leave the meat to marinate, the stronger the flavor will be. If you want, start soaking the tenderloin in the morning and leave it until you’re ready to cook dinner.

The only keto-friendly substitute for brown sugar is Sukrin Gold. If you’re following a keto diet, you may want to keep this on hand — it’s in a ton of Keto in Pearls recipes. You can find Sukrin Gold on Amazon for around $10.

Do not get nervous and kick up the cooking time. For a juicy and tender Instant Pot Pork Tenderloin with Pan Sauce, this method does work! The key is letting the tenderloin rest in the Instant Pot before you open and rest again on the platter while you make the sauce.

Your pork is fully cooked at 145 degrees Fahrenheit.

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. Or, try my Sugar Free Teriyaki Sauce recipe!

When I serve Instant Pot Pork Tenderloin with Pan Sauce, I cut my medallions in about 1.4″ pieces, but the size can vary depending on the size of your tenderloin. Even after feeding the adults and the kids, there are still plenty of leftovers.

Best Keto-Friendly Side Dishes for Pork Tenderloin

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 Instant Pot 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!

How to Store

Let your pork tenderloin cool to room temperature before storing leftovers. There’s actually a reason for this: letting your food cool prevents moisture from building up (which causes food to spoil faster).

If you want to just refrigerate your leftovers, you can put either sliced or the whole tenderloin in an airtight container. Instant Pot Pork Tenderloin can stay fresh in your refrigerator for up to 4 days.

Freezing your leftovers is also an option. First, wrap your pork tenderloin in plastic wrap or aluminum foil. Then, put the tenderloin in either an airtight container or a freezer bag. Don’t forget to label your leftovers; they’ll only stay fresh for up to 3 months.

When you’re ready to reheat, just pull it from the freezer and either let it thaw overnight or use your microwave. Once thawed, you can use either your oven, microwave, or stovetop to warm your pork tenderloin until it’s heated through.
