You'll only need beef chuck, vegetables, and a few other simple ingredients to make this easy recipe.
Start by adding the flour, salt, and pepper to a large bowl, and coat the cubed beef.
Next, add the beef to a large Dutch oven in small batches until cooked. Then set aside.
Now, put the onions into the pot and cook for 3 minutes until tender. Then set aside.
Simmer the beer, beef broth, and tomato paste. Then add in all remaining ingredients except for cornstarch and water, and continue simmering.
Mix the cornstarch and water to create a slurry. Then add it to the stew.
Serve your Guinness Beef Stew over a bed of rice or mashed potatoes, and dig in!
