Corned beef is well known as a St. Patrick’s Day staple, but it is so versatile it can really be enjoyed year round. This recipe uses Guinness to infuse the corned beef with even more Irish flavors as well as keep the meat moist and tender. The brown sugar also helps to tenderize the meat, balances the bitterness from the beer, and adds a rich caramelized coating to the beef.

I like using Guinness in this recipe because it is easy to find in most grocery stores and has a mild creaminess that complements the corned beef well. If you have a preferred stout you love, go ahead and use it! There are many craft varieties to choose from these days, including some with notes of coffee or chocolate that would be interesting. Avoid any stouts with sweet dessert flavorings such as vanilla or cinnamon, as those would likely clash with the beefy flavors. If you’d like to avoid alcohol altogether, simply substitute beef broth for the Guinness.

Corned beef is made from the brisket cut of the cow, which is why it lends itself to a slower cooking process to break down the meat. It has already been cured and brined with some herbs and spices, which gives it that distinct flavor. By adding brown sugar and Guinness, you’ll balance those strong flavors with a hint of sweetness.

Guinness Corned Beef would be the perfect centerpiece to an Irish feast served with Roasted Cabbage Steaks, Roasted Carrots, and Scalloped Potatoes. Turn the leftovers into the best Reuben Sandwich you’ve ever had!
