Why You Need to Make This Recipe

I've never met a holiday I didn't love, I never turn down an opportunity to host, and I'm ready for any excuse to celebrate. So it probably comes as no surprise that I throw a St. Paddy's Day celebration every year. This slow cooker Guinness corned beef makes an annual appearance, which means it’s a well-tested, beloved favorite.

Hey, I wouldn’t serve it year after year if it wasn’t a hit. True story.

To make the most unbelievably delicious corned beef, we cook our meat low and slow in plenty of spices for a burst of flavor in each bite. Corned beef is a cured brisket, which is a tough cut that requires a low temperature and long cooking time to break down. But once it does, we’re rewarded with an ultra tender slab of meat.

And best of all, this corned beef takes little prep time and couldn't be easier to make. Can you pour a beer? Measure a few spices? Great! You have all the skills necessary to make this slow cooker corned beef and look like a culinary genius in the process.

Bonus: If you need some other St. Patrick's Day dinner ideas, my Guinness lamb stew is another delicious option! Or you can try another cooking method and make my smoked corned beef.

Flat-Cut vs. Point-Cut Corned Beef

Typically, when you pick up corned beef at the grocery store, it comes as either flat-cut or point-cut brisket. This recipe works for both cuts. Ultimately, it comes down to your preference.

Flat-cut corned beef is leaner than its point-cut counterpart, which has more fat marbling. Because the butcher doesn't trim the fat from the point-cut corned beef, it's generally cheaper. I happen to love the butteriness a little fat adds to beef, but if you prefer lean meat, you'll be happier with the flat-cut corned beef. Extra fat or not, both cuts come out incredibly tender in the slow cooker, so you can't go wrong either way.

Step-by-Step Instructions

Get ready for one easy recipe. Seriously, I don't think an easier recipe exists.

To make our Guinness corned beef, we remove it from the bag and locate the included spice mix. Even though we're adding our own spices, I like to still use this packet for an extra flavor boost. If you happened to misplace the packet, here's a recipe for making your own corned beef spices.

Now we add our Guinness, beef bouillon, spices, the contents of the seasoning packet, brown sugar and Worcestershire sauce to the slow cooker. We stir everything to combine, place our corned beef inside the liquid and cook low for eight hours.

That's it! With hardly any effort, we now have one unbelievably tender slab of corned beef ready for your St. Patrick's Day celebrations.

See? I wouldn't lie to you. Cooking doesn't get easier than this Guinness corned beef.

How to Serve

As you can see in the photos, I shredded my corned beef. I've always been a shredded brisket kind of lady, and I bring that attitude to my corned beef as well. Plus, I find shredded corned beef is easier to serve and eat a party. I simply shred the corned beef with two forks right in the slow cooker, and then people can add piles of shredded corned beef to bread, buns or right on their plate for easy eating with no knives involved. Shredded corned beef is also great if you plan to use it for Irish nachos or something similar.

However, if you prefer corned beef slices, you can certainly serve it that way. Just make sure you slice the corned beef against the grain for better texture.

Perfect Pairing

Our perfect beer pairing is obvious, right? Grab some Guinness and call it a day. After the corned beef slowly cooks, you'll find it picks up a lot of those spices. The roasted malt is a delicious match for the warm cloves and other savory flavors.

Looking for a wine? I love a pinot noir. With a pinot noir, we get these earthy notes that pair beautifully with our spicy cloves and mustard powder. Pinot noir also comes with a nice acidic bite, which livens up those spices and cuts through the fat.

Or maybe you're looking for a festive St. Patrick's Day cocktail. My Irish mule or Irish whiskey smash are delicious options.

For a festive St. Patrick's Day celebration, I hope you try this slow cooker Guinness corned beef. This crowd-pleasing, easy recipe will make entertaining a breeze.

Cheers!
