Instant Pot Mississippi Pot Roast

The Instant Pot Mississippi Pot Roast cooks chuck roast steak with spices and pepperoncini peppers in a pressure cooker, resulting in tender, flavorful beef infused with savory and mildly tangy elements. A mix of dry herbs and seasoning powders complements the roast, and a buttermilk-cornstarch mixture is used to thicken the cooking liquid into a rich gravy. This one-pot meal simplifies traditional pot roast preparation with consistent moist cooking and concentrated flavors.

Description

Instant Pot Mississippi Pot Roast starts with a well-marbled chuck roast seasoned with kosher salt, black pepper, onion powder, garlic powder, and a blend of dried dill, parsley, chive, and other herbs. The beef is browned in olive oil in the Instant Pot using the sauté function, developing a caramelized crust that locks in flavor and juices.

After browning, chicken stock is added to deglaze the pot, which releases the browned bits from the bottom. A handful of pepperoncini peppers are included in the cooking liquid, imparting a subtle tang and slight spiciness. The roast cooks under pressure, which tenderizes the meat thoroughly in a fraction of traditional stovetop or oven time.

Once cooked, a thickening mixture made from buttermilk and cornstarch is stirred in to create a creamy, lightly tangy gravy enriched by the pan juices and seasonings. This gravy complements the tender beef and can be served over mashed potatoes or rice.

The recipe depends on the Instant Pot's ability to maintain high pressure and heat for evenly cooked meat. Browning the roast beforehand enhances both flavor and texture. Using pepperoncini peppers adds a distinctive flavor note that defines this version of pot roast.
