Instant Pot Balsamic Pork Roast

Instant Pot Pork Roast is a great easy dinner, and we loved this pork roast that’s flavored with balsamic vinegar. And this post has a link to my recipe for Slow Cooker Pork Roast as well, if you’d prefer that version.

Instant Pot Pork Roast that’s flavored with balsamic vinegar is a dinner that will impress your family or friends. I hope you can tell how delicious this was, because Kara and I swooned over this pork roast when we tested the recipe! I’m recommending it for my Friday Favorites pick this week to encourage you to try this delicious pork dinner.

For a long time now I’ve had a note to myself to try an Instant Pot version of my popular pork roast made in the Slow Cooker, and we were so happy with how the Instant Pot Pork Roast turned out! And this pork roast recipe was so quick and easy to make in the Instant Pot!

We used the same Rosemary Garlic Seasoning 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. I hope you try this recipe!

What ingredients do you need for this recipe?

• 3 lb. pork loin roast
• Rosemary Garlic Seasoning or other rub of your choice to season pork (see below)
• Olive Oil (affiliate link)

Do you need Rosemary Garlic Seasoning to make this pork roast?

I’m a fan of the Rosemary Garlic seasoning I use in both the Instant Pot and Slow Cooker recipes for pork roast. But if you don’t want to bother with making that, I’d use a generous teaspoon of Garlic Powder (affiliate link) and Ground Rosemary (affiliate link) to season the pork. Or you can use any type of seasoning blend you have on hand that’s good on pork!

This pork roast was great with the Rosemary Garlic Seasoning 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.
