Since I first published this corned beef brisket recipe, it’s become a go-to reader favorite and here’s exactly what to look for as it cooks:

  • Tenderness target: Baked until a fork slides in with little resistance and slices bend without crumbling.
  • Salt control: A quick pre-boil helps dial back the briny bite so the flavor tastes balanced, not overly salty.
  • Glaze: Dijon and brown sugar melts into a glossy, sweet-tangy coating as it bakes.
  • Broiler finish: golden broil finish is perfect for the top. Look for a deep golden-brown, lightly crisp top and caramelized at the edges, not burnt.
  • Ensures a juicy results when slicing: remembering to rest before slicing, so the brisket stays moist and cuts cleanly.

Ingredients Tips and Substitutions

labeled ingredients to make the corned beef brisket in the oven.
  • Corned Beef Brisket – make sure to get uncooked corned beef brisket. I like to get closer to 4 lb. one so that we have leftovers. Remember, you can easily increase the amount of Dijon mustard and brown sugar to cover a larger brisket.
  • Dijon mustard – make sure to use Dijon mustard, NOT yellow mustard. Some other gourmet mustards can be used, just try not to use ones with competing flavors.
  • Brown sugar – it’s okay to use either light or dark.

Success Tips for Tender Corned Beef Brisket

Before you start, these simple tips help you bake a tender corned beef brisket with the right doneness, the right salt balance, and a perfectly browned glaze:

  • Quick salt-control step (optional but helpful): For a less briny result, briefly boil the brisket, then discard the water and pat the meat dry before adding the topping.
  • Brown sugar coverage: spread the brown sugar evenly so it melts into a smooth glaze. Thin or patchy spots can brown unevenly.
  • Bake time rule and doneness: Plan roughly about 60 minutes per pound covered, then check for tenderness. Your goal is a fork sliding in with little resistance.
  • Rest for juicy slices: Rest the brisket 10-15 minutes before slicing so it stays moist and cuts cleanly.
  • Broiler finish without burning: Broil on low and keep the pan a safe distance from the element. You want deep golden-brown and caramelized, not scorched.
  • Add veggies (optional): Add potatoes and/or cabbage during the final stretch (last 45-60 minutes) of baking so they cook through without turning mushy.

How To Make Corned Beef Brisket In The Oven – Visual Guide

  1. DO take the extra step to boil the corned beef before cooking, don’t skip this step.
  2. Discard the seasoning packet, you won’t be using it since. (I skip it because it’s packaged with raw meat so can’t save for later and mustard/sugar is enough flavor for this method.)
  3. Keep the brisker in the pot just until water starts to boil. Then, turn the heat off and take the brisket out.

  1. Use a generous layer of Dijon mustard and then brown sugar all over the top and sides.
  2. Close the aluminum foil, covering the brisket loosely, leaving a little space between the brisket and the foil. You are creating a “pocket.”

  1. Bake covered until the brisket is fork-tender (for the time estimate, use the per-pound guide in the recipe card), then start checking for tenderness near the end.
  2. Once cooked, open the foil and caramelize the top under the broiler. If available, use the low broiler setting and set the oven rack about 8 inches away from the broiler.
  3. Let the corned beef brisket rest on the cutting board for about 10-15 minutes before slicing it.

Storing and Reheating Instructions

  • Store leftover cooked brisket in an air-tight food storage container, in the refrigerator. Properly stored, it should be good for 3-4 days.
  • To reheat the sliced of corned beef brisket, I recommend doing it in the oven to preserve the juiciness. Wrap some slices in foil and reheat in the oven at 350°F just until heated through.

Recipe FAQs

Do I really need to boil the corned beef first?

No, since this is an optional step. Boiling briefly helps reduce excess salt and gives you a more balanced flavor, but you can skip it if you like a stronger, brinier bite.

How do I know when corned beef brisket is done?

It’s done when it’s fork-tender a fork slides in with little resistance and the meat feels soft rather than springy or rubbery.

My corned beef is still tough, what went wrong?

It just needs more time. Keep it tightly covered and continue baking, checking tenderness every 15-20 minutes until it softens.

What is target internal temperature for tender cooked corned beef?

Optimal internal temperature you’re looking for is 195°F-205°F. It will be more and more tender closer to 205°F but it will be more at the fall-apart stage.

How do I slice corned beef brisket so it’s tender?

Let it rest, then slice against the grain (look for the lines in the meat and cut across them) for the most tender slices.

Ingredients

  • 2-4 lb corned beef brisket
  • 3-4 Tbsp Grey Poupon Dijon mustard (more for larger brisket)
  • 3-4 Tbsp brown sugar (more for larger brisket)

Instructions

  • Take the brisket out of the package and discard the spice pack that comes with it.
  • Place brisket in a pot of water and bring it to boil. As soon as it starts to boil, take the brisket out. This will remove some of the excess salt in the meat.
  • Preheat the oven to 350°F.
  • Place the brisket, fat layer up, in the middle of aluminum foil big enough to cover the whole brisket.
  • Rub the whole brisket with Dijon mustard. Then, evenly sprinkle brown sugar over the top and gently pet it on. Pat some onto the sides as well.
  • Bring the aluminum foil together and close it, covering the brisket loosely, leaving a little space between the brisket and the foil. Place the covered brisket into a rimmed roasting pan.
  • Bake it for 2 hours. Open the foil and turn on the broiler on low, if you have an option for low or high broiler setting. (If not, move the brisket to a lower rack.) Let the top caramelize for a few minutes but watch it so it doesn’t burn.
  • BAKE TIME: the 2 hours recommendation time is for the 1.75-2 lb. sized corned beef brisket. If you have a larger piece of meat, you will need to cook it longer. Give it about 45-60 minutes per pound. Lean towards the 60 minutes per pound time. 
  • Take the corned beef brisket out and let it rest for a 10-15 minutes on the cutting board before slicing.
  • Make sure to slice the meat against the grain! Luckily, with the corned beef brisket, it's very easy to see the grain.

Notes

  • Why boil first? Since corned beef is cured in salt brine, it contains quite a bit of salt. So bringing the corned beef to a boil in a pot of water, gets some of the saltiness out.
  • Adding potatoes and/or cabbage: You absolutely can add some potatoes and if you wish cabbage and carrots to the brisket. Since beef will take MUCH longer to cook than vegetables, you will need to cook the brisket for a while first. Baby gold potatoes will need about an hour of total cook time, covered and uncovered. So set aside about an another hour at the end of meat’s cooking time to cook potatoes.
    If your potatoes are larger, you can always cut it in half.
    If you wish to add cabbage, cut the head of cabbage into 4-6 wedges and place them around the meat. Depending on the size of the cabbage wedges, it would take 45-60 minutes.
    You can see the steps and get the idea of how to cook it in my Baked Corned Beef Brisket and Potatoes recipe.
  • Store and reheat: Store leftover cooked brisket in an air-tight food storage container, in the refrigerator. Properly stored, it should be good for 3-4 days.
    To reheat the sliced of corned beef brisket, I recommend doing it in the oven to preserve the juiciness. Wrap some slices in foil and reheat in the oven at 350°F just until heated through.

    I’ve made corned beef like this for many years. It’s wonderful and once you’ve tried it you’l never boil again!

    1. I agree! A lot more flavor than boiling!

  7. I have a 7 pound corned beef brisket. According to the time per lb it will take about 7 hrs to cook. Should I lower the temp for such a long time. I don’t want to dry the meat out or burn it.

    1. Hi Lisa,

      That’s a big brisket! Yes, you would want to cook it at the same temperature and it will take 5-7 hours. I hope you enjoy it!

  8. It is by far the best corn beef I have ever cooked. I tell you it the first time I didn’t have any leftovers for the next day. It is a must try recipe.

    1. What a sweet compliment! Thank you, Elaine! I am so pleased your family enjoyed it!

      first time i made this last year according to directions it was 4 star good. tonight i spaced out and mixed the mustard and sugar together and had a very barky burnt (black in spots) top, so much so i had to flip it halfway. my roommate still loved it and i loved the burnt bits myself!

      1. Did you get a new oven? Maybe it runs a little hot? I am glad you still liked it though!

  12. 5 stars

  14. 5 stars
    The best, easiest and most delicious way to prepare corned beef. I use the spicy brown mustard instead. I put in a baking pan of potatoes, carrots and cabbage to roast along with it.

    1. Awe, thank you, Barb! I am so glad you liked it! 🙂

    Hands-down the best corned beef I have ever cooked. For over 30 years I have always slow cooked my corned beef in water, which was always hit or miss. In the last couple years, I have made this recipe many times and have tweaked it out a little. I follow the directions above but I do add the spice packet and a teaspoon of minced garlic to a cup of warm water and pour it in the bottom of the foiled pan before placing in the oven. Comes out perfectly tasty every single time. Thank you so much for sharing this recipe!! <3

    1. Thank you for the sweetest comment! I am so glad you liked it!

  17. I poured out the water that had collected in the foil after 45 minutes, will this ruin the corned beef

    1. Hi Amy! It should’ve came out good still please let me know what you thought! 🙂
