Slow Cooker Maple Mustard Corned Beef

Maple and Mustard flavor this easy Slow Cooker Corned Beef which is perfect for a change of pace on St. Patricks Day.

For the last few years I’ve made a standard Corned Beef and Cabbage. Though that meal turns out great, I really wanted to step this meal up a notch. The first thing I did differently was I ditched that pickling seasoning packet that comes with the corned beef.

Slow Cooker Maple Mustard Corned Beef

This was the first time I’ve cooked a corned beef without the pickling packet, and I have no regrets! I could taste the true flavor of the meat, and I didn’t have peppercorns popping in my mouth. This is a fun and unique recipe to try for St. Patrick’s Day.

How to make Maple Mustard Corned Beef:

  1. Choose a corned beef, I use flat cut if I can find it though point cut works great too!
  2. Gather your ingredients; cooking oil to brown the corned beef, maple syrup, yellow mustard, garlic and black pepper.
  3. Mix together the sauce ingredients. Set aside.
  4. Brown the corned beef on all sides.

  • Pour the maple-mustard mixture over the corned beef. Place the lid on the slow cooker.
  • Cook for 7 hours on low.
  • Serve and enjoy.

      I wanted to do themed St Paddy’s Day dinners a few years ago and came across this recipe. It is the best corned beef recipe I have ever had! I thought that I would experiment with different recipes each year, but we love this so much, we make it every year! If you try it, you will be hooked like our family. It is in my crock pot as I type this comment and we are loving the smell and looking forward to dinner time. Did I mention the simplicity of this as well?

      Hi – making this now – so excited to see how it turns out. Only problem – I didn’t start it soon enough to have it on low for 7 hrs. Can I cook it on high for less, or should I start it on low and turn up to high later? Thanks!

      I made this tonight. The flavor was awesome! We bought a flat from Meijer, I rinsed and then dried the beef before browning. Followed the directions to a tee. After 7 hours on low I tasted it and it was very salty! Is there a way to get the salt out? Is it maybe the quality of the meat? Looking for suggestions as I want to make this again.

        It is a very salty cut of meat, it’s brined in a salt solution. BUT that being said, you could try this recipe with a beef brisket (which is just a roast, not brined). I hope that helps.

      Absolutely delicious! I mixed yellow and dijon mustard and added one cube of beef bullion, and cooked exactly as directed. Totally will make again.

      I have never browned my corned beef cut before cooking it, either on the stockpot or slow cooker. Is it really necessary?

        Definitely adds a nice touch, I like the flavour. Just give it a try next time and see if you like it enough to add it into your usual recipe 🙂

      I buy a low salt corned beef at the grocery store – for those of you who thought it was too salty or want to boil first. I made this recipe last year & it was the only good (really GREAT) corned beef I had made in years! I had given up making it for St. Paddy’s Day but not anymore! I’m going to borrow my son’s crockpot so I can make two this year to feed everyone.
