I hope you can tell from the photos that this Instant Pot Balsamic Pork Roast was absolutely amazing because Kara and I swooned over this when we tested the recipe! For a long time now I’ve had a note to myself to try an Instant Pot version of the popular Slow Cooker Balsamic Pork Roast on the blog, and we were so happy with how the Instant Pot pork roast turned out

And this was so quick and easy to make in the Instant Pot! We used the same Rosemary and Garlic Herb Rub that I liked so much for the slow cooker version, but if you don’t want to make that mixture, just substitute any seasonings that are good with pork. I used pork loin roast from Costco, which was inexpensive as well as being delicious, and this made eight servings for a main dish that’s perfect for a special meal!

What ingredients do you need for this recipe?

  • 3 lb. pork loin roast
  • Rosemary and Garlic Herb Rub or other rub of your choice to season pork
  • olive oil
  • cup beef stock (see notes)
  • balsamic vinegar

Notes

This pork roast was great with the Rosemary and Garlic Herb Rub but if you don't want to bother making that use any ground herbs and spices that are good with pork. Beef broth from a can is fine if you don't have Homemade Beef Stock.
