Equipment

1 pressure cooker

Ingredients

3 lb roast we have used chuck roast (best cut) and top round roast, cut into thick strips
2 tbsp olive oil to saute
1 small onion diced, optional
1/2 cup beef broth
3 tbsp ranch dressing mix or 1 packet
1 packet gravy mix I used McCormick mushroom gravy
1/2 cup peperoncini juice
1 tbsp worcestershire sauce
8-10 large peperoncini peppers
1 stick butter
2 tbsp cornstarch only use if you want to thicken liquid at the end to make a thicker gravy, I chose not to

Instructions

Cut beef into large strips (so they'll get more tender in the hour time). Mine were about 1.5" thick x 3" long.
Sprinkle with salt and pepper. Set pot to saute and add olive oil. When hot add meat and brown outsides. Then turn pot off and use wood spatula to scrape any stuck on bits off bottom of pot. (can use a bit of your broth if you need to, I didn't)
In a small bowl whisk together the beef broth, peperoncini juice, ranch dry mix, and gravy packet until smooth. Pour this on top of your meat.
Put whole peperoncini peppers on top of that with your stick of butter in the middle of everything.
Close lid and vent, set to high pressure for 60 minutes followed by a natural release of pressure. That will take 25-30 minutes.
Take out peppers and remove stems, then cut into smaller pieces and return to pot. Serve as is or break up chunks into shredded beef and serve.
If you want a thicker gravy, remove meat and peppers. Set pot to saute. In a small bowl add 2 tbsp cornstarch + some of your hot liquid. Whisk together until smooth. Pour that in and let it bubble and thicken. Then pour on top of meat and serve with rice or mashed potatoes.

Notes

with Frozen Roast

You will skip the saute step with a frozen roast. Instead use the same ingredients for the sauce above but the timing will increase to 1 hour 30 minutes like in our recipe for Instant Pot frozen chuck roast
