Sabrina’s Guinness Corned Beef Recipe
Corned Beef is well known as a St. Patrick’s Day staple, but it is so versatile that 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.

About this Recipe
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.
What is Corned Beef?
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.
What to Pair With
This meat 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!
How to Store
- Serve: Beef can be kept at room temperature up to 2 hours before needing refrigeration.
- Store: Store in an airtight container in the refrigerator for up to 3 days.
- Freeze: Freeze leftovers in a freezer-safe container for 2-3 months. Defrost in the refrigerator overnight and reheat in the oven or stovetop. You may want to add a half cup of Guinness or beef broth when reheating.
Alternative Cooking Techniques

Hi! Question: If I wanted to do this recipe in the slow cooker, would you suggest doing this recipe but put it in the slow cooker, or doing your slow cooker recipe and replacing the water with the Guinness? Thank you.
Made this last year and it turned out great! The answer to my question is buried in the page and I found it. Thanks for the recipe. Going to try this in the Instant Pot this year. Based on past experience, I’m going to sear the beef (in the IP or on the stove if the IP is to small) about 3-5 min on each side while the IP is on the sauté function prior to doing your directions. 🙂
Hi Sabrina,
Looking forward to making this. What is in the spice packet and where does one usually find a spice packet for this recipe??
Thanks,
Niki
