Insanely Delicious Instant Pot Beef Stew Recipe. This Instant Pot Beef Stew (With A Secret Ingredient) is the BEST beef stew with fork-tender beef, potatoes, and vegetables in a rich, savory gravy that is ready in an hour. While I love making beef stew using the traditional method, I love making it in my Instant Pot even more. It was the first recipe I made after I got my Instant Pot, and is still one of my favorite Instant Pot recipes.
