This hearty dish features tender corned beef slow-cooked in rich Guinness beer, making each bite full of flavor. It’s perfect for a cozy meal!
My favorite part? The smell that fills the kitchen while it cooks! I love serving it with creamy mashed potatoes. It’s a winner at every dinner table! 🥔✨
Key Ingredients & Substitutions
Corned Beef Brisket: This is the star of the dish! Look for a brisket that comes with a spice packet; it makes seasoning easy. If you’re looking to make a leaner version, try using a turkey or chicken breast, though it won’t have the same flavor or texture.
Guinness Stout: This beer adds depth and richness. If you can’t find Guinness, any dark stout or porter will work well. For a non-alcoholic option, consider using beef broth or malt extract mixed with water for a similar taste.
Vegetables: Carrots and baby potatoes are perfect here, but you can switch them up! Parsnips or sweet potatoes can add a unique flavor. I like mixing potato colors for a fun presentation!
Mustards: Dijon mustard is a must for that zing! You can skip the whole-grain mustard if you don’t have it, but the texture it adds is nice. Honey mustard can be a sweeter alternative.
How Do You Achieve Tender Corned Beef?
Cooking corned beef properly is key to getting that tender texture. The low and slow simmering process is what breaks down the tough fibers in the meat.
- Start with rinsing the brisket. This helps remove excess salt which can make the dish too salty.
- Simmer the corned beef for at least 3 hours on low heat. Don’t rush it! Patience pays off.
- Check for tenderness; it should fall apart easily when ready.
After cooking, don’t forget to rest the meat covered. This helps the juices redistribute, making every slice juicy and delicious!

How to Make Guinness Braised Corned Beef
Ingredients You’ll Need:
Main Ingredients:
- 4-5 lb corned beef brisket, with spice packet
- 2 tbsp olive oil or vegetable oil
- 1 large onion, sliced
- 4 cloves garlic, minced
- 3-4 carrots, peeled and cut into large chunks
- 1 lb baby potatoes (mixed colors if preferred)
Flavorful Additions:
- 3 cups Guinness stout beer
- 2 cups beef broth
- 2 tbsp brown sugar
- 2 tbsp Dijon mustard
- 2 tbsp whole-grain mustard (optional, for crust)
- 1 tbsp black peppercorns
- 4-5 whole allspice berries (optional)
- 2 bay leaves
For Garnishing:
- Fresh parsley, chopped
- Salt and pepper to taste
How Much Time Will You Need?
You’ll need about 20 minutes to prep your ingredients, and then about 3 hours for the corned beef to simmer until tender. After that, there’s a brief oven roasting time of about 15-20 minutes. In total, you’re looking at around 3 hours and 40 minutes, but much of it is hands-off cooking, leaving you time to relax!
Step-by-Step Instructions:
1. Prepare the Corned Beef:
Start by rinsing the corned beef brisket under cold water. This removes some of the saltiness and helps improve the flavor. Place the brisket in a large pot or Dutch oven to get ready for cooking.
2. Add the Spices:
Take the spice packet that comes with the corned beef and add it to the pot. Then, toss in the black peppercorns, optional allspice berries, and bay leaves. These spices will create a rich flavor as the meat cooks.
3. Add Liquids:
Pour in the Guinness stout beer and beef broth, ensuring the brisket is almost covered. Stir in the brown sugar to add a touch of sweetness to the dish. Bring this mixture to a boil over medium-high heat!
4. Simmer the Meat:
Once boiling, reduce the heat to low, cover, and let it gently simmer for about 3 hours. You’ll know it’s done when the meat is tender and juicy. Make sure to check occasionally!
5. Prepare the Vegetables:
While the meat cooks, go ahead and prepare your veggies! Peel and cut the carrots, and rinse the baby potatoes to get them ready for the pot later.
6. Cook the Vegetables:
After 3 hours, carefully remove the brisket and cover it to keep warm. Add the carrots and potatoes to the flavorful cooking liquid. Let them simmer for about 20-25 minutes, or until they are tender.
7. Preheat the Oven:
While the veggies cook, preheat your oven to 375°F (190°C). This will prepare for the final roast of the brisket.
8. Prepare the Mustard Crust:
Take the reserved brisket and brush the top with a mix of Dijon and whole-grain mustard. This will add a fantastic crust when it roasts in the oven!
9. Roast the Brisket:
Place the brisket in a baking dish and roast it in the oven for 15-20 minutes. You want the mustard topping to be set and lightly browned for a delicious finish.
10. Slice and Serve:
Once roasted, let the brisket rest for a few minutes before slicing. Cut against the grain into thick, juicy slices.
11. Plate It Up:
Serve the slices alongside those tender carrots and potatoes. Don’t forget to drizzle some of the flavorful braising liquid over everything!
12. Garnish and Enjoy:
Finish off by garnishing with chopped fresh parsley and seasoning with additional salt and pepper to taste. Enjoy your hearty and flavorful Guinness Braised Corned Beef!
Can I Use a Different Type of Beer?
Absolutely! While Guinness offers a rich flavor, you can substitute it with any dark stout or porter. For a non-alcoholic version, try using beef broth with a splash of malt extract for a similar depth of flavor.
What If My Corned Beef Is Too Salty?
If you find your corned beef too salty, try rinsing the brisket more thoroughly before cooking or add more water or beef broth during the simmering process. Serving the meat with plenty of the braising liquid helps balance the saltiness too!
Can I Make This Recipe Ahead of Time?
Yes, you can! Cook the corned beef and vegetables ahead of time, then refrigerate them separately. When ready to serve, gently reheat the meat and vegetables on the stovetop or in the oven until warmed through. This can enhance the flavors!
How to Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. For longer storage, you can freeze the meat and vegetables. Just be sure to cool them completely before freezing, and they should keep well for about 2-3 months. Reheat thoroughly before serving!
