How to Make Corned Beef Honey Mustard and Potatoes
If you aren’t a fan of the saltiness in corned beef, don’t give up on it just yet! Corned beef can be very salty when baked, but this recipe uses a boiling method to tame it down. By boiling the corned beef before you bake it, you get a deliciously seasoned corned beef without it being overly salty.
This corned beef and potatoes is sweet with a subtle tang. Topped with a sweet brown sugar and honey marmalade, this recipe is sure to knock your socks off!
Honey Mustard Beef and Potato Ingredients
First assemble the following ingredients.
- Corned beef– Flat cut corned beef is leaner and has a more consistent thickness. You should get either the whole brisket or the flat cut for this recipe.
- Whole grain mustard– Whole grain mustard is mustard with visible seeds. I prefer Silver Spring Whole Grain Mustard, but you can use any kind you like.
- Dijon mustard– If you don’t have dijon mustard, you can use regular yellow mustard.
- Corned beef spice packet– Typically your corned beef will come with this spice packet. If it doesn’t, you can make your own using this recipe.
- Honey– Raw honey is the healthiest and most nutritious, but you can use any honey you prefer.
- Brown sugar– For this recipe, you will use dark brown sugar. Light brown sugar will work, but the corned beef won’t be as flavorful.
- Onion– You can use any onion you prefer, but I typically use a sweet onion to pair with the sweetness of the marmalade.
- Potatoes-You won’t need to worry about peeling the potatoes. Just wash them, and cut them in half.
- Olive Oil– Olive oil is used in the bottom of the pan to prevent your meal from sticking.

Tips and Tricks for Corned Beef and Potatoes with Honey Mustard
Internal temp. Use a thermometer to check the corned beef. The beef is ready when the thickest part of the meat is 160?. It should be fork tender.
Thick cuts take longer. Extend cooking time for larger cuts of meat. This recipe is for a 2 pound beef brisket, and will take 70-80 minutes to cook.
Always boil. Don’t skip boiling the meat. This step is important to help reduce some of the salty flavor from packaging.
Broil it well. The corned beef should stay under the broiler until it is golden brown. Do not let it burn.
More Delicious Irish Recipes
Although this recipe is pretty much a meal of its own, you can make some other tasty sides while the corned beef is cooking. I would suggest Brown Butter Bacon Baked Brussel Sprouts or Fried Cabbage with Bacon. Complete the meal with a delicious side of Irish Brown Soda Bread and some easy shamrock cookies!
