To begin, cook the 2 pounds of beef over the stove until brown for about 3-5 minutes
Once the beef is cooked, mix in the vegetables and let it cook for another five
Gradually add in the seasonings. If you'd like other seasonings besides garlic and pepper feel free to add those in, they're just the seasonings I prefer!
Then pour the Guinness over top. Take everything from the pan and move it into a large pot
Add in the tomato paste and the chicken (or vegetable) stock
Let it simmer on low with a cover until the beef is cooked to the way that you'd prefer - this will normally take anywhere from 1.5 - 2 hours. Stir occasionally
When it gets close to being ready, cook your mashed potatoes to your liking
After your stew is just about ready, remove the cover and let it cook for about another 20 minutes so that it can thicken up a little bit more before you feast
Once it's ready, spoon some mashed potatoes on top and you're good to go!
