This hearty and comforting beef stew is perfect for a chilly day. In a slow cooker, combine cubed beef, chopped onions, diced carrots, diced potatoes, and beef broth. Season with salt, pepper, and your favorite herbs and spices. Cook on low for 8 hours or until the beef is tender and the vegetables are cooked through. Serve hot with crusty bread or over mashed potatoes.
