Notes
Ingredient Notes and Shopping Tips
Beef Stew Meat: Look for meat labeled beef stew meat if possible. If you can't find it, any type of tough, lean meat will do. Look for cuts with names like Chuck Roast or brisket. These types of meat hold up well in stews.
Potatoes: I like using White russet potatoes here. Cut potatoes in even chunks to ensure even cooking.
Beef Broth: Use low sodium so you can season to taste.
Tips and Tricks
Brown Meat First: The caramelized exterior adds a delicious layer of flavor to the dish. Without it, your meat may taste one-dimensional or a bit lackluster. Save your beef drippings to saute your veggies for even more flavor.
Deglaze with Beef Broth: Scrape all those yummy brown bits off after beef broth. Failure to do this may result in a "Burn Warning" halfway through cooking.
Natural Release: Unlike manual release where we turn the valve as soon as the time goes off, we'll allow the pressure to release naturally from this recipe for 10 minutes. Then, after 10 minutes we will turn the pressure release valve. I always suggest manual release for soups and stews to avoid the splattering of hot liquid.
Releasing Pressure: I like to turn the valve using the handle of a wooden spoon. Once you hear the click, all pressure is released and it is safe to open the lid.
