Instant Pot Italian-Style Pot Roast Sandwiches

Instant Pot Italian-Style Pot Roast Pot Roast Sandwiches made in the pressure cooker with stewed tomatoes, onion, garlic, and seasonings and served on a bun.

Dump and Start Pot Roast

I love dump and start meals because it makes mealtime so simple!  The prep time on this recipe takes very little time at all because most of the ingredients are either seasonings or canned.  Almost all the recipes out there for pressure cooker includes water, this one doesn't.  Don't stress, no worry to freak out!  The liquid from the cans of stewed tomatoes is more than enough liquid to prevent a BURN notice on your pressure cooker.  I use a slotted spoon to remove the pot roast and the veggies from the extra liquid.  You can also create a slurry if you want to create gravy from the extra broth.

*TIP: To create gravy from the extra broth use a slurry of 3 tablespoon of cornstarch and 3 tablespoon of water and then add into the pot while cooking on Saute.

While I make this Instant Pot Italian-Style pot roast, I shred it and serve it on a bun.  It's fork-tender so it's great to make into sandwiches.  It also makes it a great option for potlucks and picnics!  When I make this, I slice red potatoes and season them with paprika, salt, and pepper. I then fry them in my air fryer for 16 minutes.  I make them while my Instant Pot is naturally releasing pressure.  This whole meal takes very little effort and it's a complete meal!

Slow Cooker Option

This Italian-Style Pot Roast can be made in the Instant Pot with the same ingredients.  The only difference is that the cooking time is different.  To make this recipe in the slow cooker, you will cook it on the LOW setting for 6-8 hours.  In my opinion, using a pressure cooker to make this saves tons of time and you can make it on short notice (we've all been there!).  I also find that making in the pressure cooker tastes just as it would have slow cooking all day.
