You may or may not have heard of a Mississippi roast. There are a lot of different variations of this meal, but making a Mississippi roast in an Instant Pot versus a slow cooker just shaved about 6 hours off of your cooking time.
Most roasts are typically a little lackluster in flavor, but this recipe is PACKED full of flavor and will not disappoint.

- 1/2 tablespoon black pepper
- 1 large onion, diced
- 1 cup beef broth

- 1 packet au jus gravy mix
- 4 tablespoons (1/2 stick) butter
- 5-6 pepperoncini peppers
- 1/4 cup pepperoncini juice
- Turn the Instant Pot on to sauté mode. Put oil into the pot and sprinkle pepper to all sides of the roast. When the Instant Pot reads “hot,” place the chuck roast into the pot.
