Guinness Beef Stew is a favorite Irish beef stew recipe in our house. We make this slow cooker beef stew for St. Patrick's Day every year, and we just can't get enough. It's the best Guinness stew recipe and so easy to make in a Crockpot!
Put potato, carrot, and celery chunks in the bottom of crock pot on low heat. Pour in beer, beef broth, garlic powder, salt and pepper, soup mix, and basil. Stir to combine.
Season beef lightly with salt and pepper and then coat in the flour.
Heat oil over medium high heat in a large skillet. Cook the beef until almost browned, and then add in the onion. Continue turning and browning until the meat is fully browned and the onions are soft and translucent, about 5 minutes.
Add meat and onions to the slow cooker.
Stir in the tomato sauce and cover, heating on low for 8 hours or high for 4 hours. Low is best, but if you don't have the time, high will work!
Serve with lots of bread and more Guinness! Enjoy!
