ROAST – When choosing a chuck roast, grab a well-marbled cut of meat. Having a marbled cut of meat adds more flavor as the fat melts into the roast while it cooks. If you would like, you can brown the chuck roast in a pan before adding it to the instant pot, this will help retain the moisture of the meat and you guessed it, add more flavor. This isn’t a necessary step, but it’s one you can choose to do if you want!

PEPPERS – Pepperoncini peppers add so much flavor and the vinegar from the brine helps to tenderize and balance the richness. They aren’t spicy once they’ve cooked for several hours, all that’s left is a little zip in the juice and roast. If you’re concerned about spice, try it with just the pepperoncini juice instead but we don’t recommend leaving out pepperoncini peppers or juice altogether!

SEASONINGS – Ranch seasoning packets can be found at your local grocery store, or you can opt to make your own homemade ranch seasoning mix in its place. Don’t forget the au jus gravy packet! The butter is completely optional, but it enriches the gravy.
