Instant Pot Mississippi Pot Roast without the packets! This easy pot roast recipe is made from scratch with just 5 minutes of prep.

Plate of Mississippi pot roast and mashed potatoes.

Mississippi pot roast is one of my favorite roast recipes, which is funny because I don’t normally like pepperoncinis.

However, this roast is so tender and so flavorful that it’s hard to resist! I use seasonings in place of the usual onion soup and ranch packets.

This pot roast also requires little prep (only about 5 minutes!), which makes it ideal for busy weekday mornings. Check out the step-by-step photos and tips below for ways to customize this recipe.

How to make Instant Pot Mississippi Pot Roast

Chuck roast topped with spices in an instant pot inner pot.

Place the roast in the inner pot. Sprinkle the onion, parsley, onion powder, dill weed, garlic powder, salt, and pepper over the roast.

Add the beef base on top of the seasonings. Pour the beef broth around the roast.

Pot roast topped with meat and pepperoncinis.

Pour the pepperoncini juice around the roast and place the peppers next to the roast in the inner pot. Place the butter on top of the roast.

Close and lock the lid. Turn the pressure release valve to SEALING.

Cook. When the cooking time has finished, let the pressure release naturally for 20 minutes.

Turn the pressure release valve to VENTING to release any remaining pressure. Shred the meat with two forks.

What makes this recipe different?

Normally, Instant Pot Mississippi pot roast is made with a packet of ranch dressing, a stick of butter, and a packet of onion soup mix.

Since I don’t usually have those packets in my pantry, I decided to make an easy homemade version with the spices that I have. I also decreased the amount of butter to keep it from getting greasy.

Do I need to brown the roast?

I’ve tried browning the meat, but I didn’t find that it added anything to the end flavor of the dish. So, I eliminated that step to make the recipe even faster and easier.

Tips

Chuck roast: A similar cut of meat, like a rump roast, can be used in this recipe.
Onion powder/garlic powder: Be sure to use powder, not salt. Otherwise, your roast will be very salty.
Kosher salt: Or you can use ½ teaspoon of salt.
Pepperoncinis: There is just a hit of heat in this recipe. If you’d like more heat, feel free to use more peppers.

Serving suggestions

I like to serve this pot roast with egg noodles or mashed potatoes to soak up all of the juices. It’s also great on a bun as a sandwich.
