This Easy Slow Cooker Beef Stew tastes amazing. A hearty bowl of slow cooker beef stew on a cold fall or winter day is one of the best ways to warm up. Tender cubed stew meat is slow cooked in a crockpot with onion, carrots, potato, mushrooms, and savory seasonings. This is the perfect recipe for two and makes a great dinner or lunch with no pre-browning required.
