There’s nothing more cozy and comforting than a hearty meat and potatoes dinner. The rich, deep flavors of a Guinness stout are bold enough to take your pot roast to the next level! Guinness has a slight sweetness to it and a mild creamy finish, which makes it the perfect companion to the more savory flavors of beef broth, garlic, and rosemary in this pot roast.
This is a perfect Sunday dinner, because it can be prepared in the early afternoon and braise in the oven for a few hours while you relax or watch a game. Then you can enjoy the leftovers when your busy week begins! Since the carrots and potatoes cook along with the roast, they soak up all the yummy flavors and provide a side dish in this easy, one-pot meal.
As with so many pot roast recipes, it is important to take the step of deeply searing your roast on both sides before adding the liquid ingredients. Season the beef first, then make sure the oil is nice and hot. Give your roast a good few minutes on each side to achieve a dark, caramelized crust. This will not only add tons of flavor to your pot roast, it will improve the texture also!

Frequently Asked Questions About Guinness Pot Roast
The longer you cook a pot roast, the more tender it will become. This is because the meat has a lot of connective tissues that take a while to break down. However once they do you get tender meat that you can pull apart with your fork.
If you can’t find a roast that is 4-5 pounds, it’s okay to use one that is smaller. You can even use one that is larger if you have a pot it will fit in. You will need to adjust your cooking time, as a small roast will cook faster, and a large roast will take more time. Watch your roast and test it with a fork to see if it’s done.
Why Use Guinness?
Guinness is the best beer for this recipe, and no they are not a sponsor! Although there are many varieties of stout on the market, including different types of Guinness, the traditional Guinness Extra Stout is what you want. It is well balanced between bitter and sweet, with a slight roasted quality that adds a depth of flavor to this pot roast. The great thing is that if you buy a six-pack, you’ll have plenty left over to drink a perfect pairing with dinner! If you prefer a stout from a different brewery, just make sure it has similar balanced flavors and is not heavily bitter or sweet.
How to Serve Guinness Pot Roast

For leftovers, a juicy Pot Roast Sandwich would make an excellent lunch or dinner.
