Key Ingredients & Substitutions
Corned Beef Brisket: This is the star of the dish. Look for a brisket with good marbling for tenderness. If you can’t find corned beef, try using a similar cut of brisket and brining it yourself for a few days in saltwater with spices.
Dijon Mustard: This adds a lovely tang. If you’re looking for a milder taste, you could swap it with yellow mustard. Alternatively, use whole grain mustard for added texture and flavor.
Brown Sugar: While brown sugar adds sweetness, you can use honey or maple syrup as alternatives. They will give a different flavor twist, akin to caramelizing your glaze.
Apple Cider Vinegar: For a similar acidity, white wine vinegar or red wine vinegar would work well. If you’re looking for a non-vinegar option, a squeeze of fresh lemon juice can be a bright substitute.
Parsley: This is optional for garnish but adds a fresh touch. If you don’t have parsley, try fresh thyme or chives for a nice vibrant addition.
How Do I Ensure My Corned Beef Is Tender?
The key to tender corned beef is slow cooking. Always start by rinsing the brisket to remove excess brine, which can make it too salty. Here’s how to slow-cook it perfectly:
- Simmer gently in a pot with water and aromatics (onion, garlic, bay leaves, and peppercorns) for about 2.5 to 3 hours.
- Make sure to keep the pot covered to lock in moisture, avoiding high heat that can dry out the meat.
- Check if the meat is tender by piercing it with a fork—if it easily pulls apart, you’re good to go!
Letting the meat rest for about 10 minutes after cooking is crucial. This helps the juices redistribute, keeping your slices juicy. Enjoy the process—it’s worth the wait!

How Much Time Will You Need?
This recipe involves about 10 minutes of prep time, followed by 2.5 to 3 hours of simmering, and 20 to 30 minutes for roasting. Overall, you’re looking at around 3 to 4 hours to enjoy this delicious corned beef dish!
Step-by-Step Instructions:
1. Rinse and Prepare the Brisket:
First, rinse the corned beef brisket under cold water to get rid of any excess brine. This will help reduce the saltiness in the final dish.
2. Start Cooking the Brisket:
Place the rinsed brisket in a large pot or Dutch oven. Add the 4 cups of water, quartered onion, smashed garlic, bay leaves, black peppercorns, and the spice packet that came with the corned beef. This mixture will give your meat plenty of flavor while it cooks.
3. Simmer the Brisket:
Bring the pot to a boil, then turn the heat down to low. Cover the pot and let the brisket simmer gently for about 2.5 to 3 hours. You’ll know it’s ready when the meat is tender and easily pierced with a fork.
4. Preheat the Oven:
While the brisket is cooking, preheat your oven to 375°F (190°C). This will get your oven ready for roasting the meat later.
5. Make the Mustard Glaze:
Once the brisket is done simmering, carefully remove it from the pot. Reserve about 1/2 cup of the cooking liquid. In a small bowl, whisk together the Dijon mustard, brown sugar, apple cider vinegar, Worcestershire sauce, ground black pepper, and the reserved cooking liquid to create a tasty mustard glaze.
6. Prepare for Roasting:
Place the brisket in a roasting pan or baking dish. Generously brush the mustard glaze over the top of the meat so it can caramelize beautifully in the oven.
7. Roast the Brisket:
Pop the roasting pan into your preheated oven and roast for 20 to 30 minutes. Remember to baste with any extra glaze you have halfway through to achieve that glossy finish. You want it caramelized and bubbly!
8. Let it Rest:
Once it’s done roasting, remove the brisket from the oven and let it rest for about 10 minutes. This resting time helps the juices redistribute, so your slices will be nice and juicy.
9. Slice and Serve:
Slice the corned beef against the grain into thick slices. Don’t forget to sprinkle some chopped fresh parsley on top if you’d like for a garnish. Serve it warm, and offer some extra mustard glaze on the side for those who want a bit more zing!
Enjoy your flavorful Corned Beef With Mustard Glaze!
Can I Use a Different Cut of Meat?
Yes, you can use a similar cut like a pork brisket or even a beef round. Just keep in mind that cooking times may vary. Make sure to adjust your simmering time based on how tender the meat becomes!
What Can I Substitute for Dijon Mustard?
If you don’t have Dijon mustard on hand, yellow mustard works fine for a milder flavor. Alternatively, consider using whole grain mustard for added texture and depth.
How Long Do Leftovers Last?
Leftover corned beef can be stored in an airtight container in the fridge for up to 3 days. For longer storage, freeze the sliced meat wrapped tightly in plastic wrap and aluminum foil for up to 3 months. Thaw in the fridge before reheating.
Can I Cook This in a Slow Cooker?
Absolutely! You can place the rinsed brisket and other ingredients in a slow cooker and cook on low for about 8 hours or until tender. Afterward, follow the same steps to make the mustard glaze and roast it in the oven for that caramelized finish.
