Slow Cooker Corned Beef Dinner with Mustard Sauce
I have corned beef about once a year around St. Patrick’s Day. After I made this last night I wondered why I only make it once a year! It was so tasty. My kids kept eating and eating until it was almost completely gone! They loved it. I was hoping to use some of the leftover corned beef to make split pea soup today but there’s not enough left! Maybe I’ll have to make another corned beef today just so I can have some leftovers.
What made this dinner stand out to me was the sour cream mustard sauce that we served with it. My son literally kept putting spoonful after spoonful on top. He loved it! It’s not a necessity but I think you’ll really love it too.
To make Slow Cooker Corned Beef Dinner with Mustard Sauce I prefer to cook the beef for a while on it’s own and then add the vegetables in a little bit later. That way you don’t end up with totally mushy vegetables. If you can’t do this for time reasons then you can add the vegetables in at the beginning, but I would suggest using large chunks of the vegetables or even whole potatoes and whole carrots.

What Slow Cooker Did You Use?
To make Slow Cooker Corned Beef Dinner with Mustard Sauce I used my 6 quart oval Kitchenaid slow cooker.* I love this slow cooker (you can see me talking about it in a video here). It cooks low and evenly. I love the medium heat choice because most slow cookers that I’ve seen only have the option of cooking on low or high. If you’re going to buy just one slow cooker, this is the one that I recommend.Print

For the corned beef:

This was delicious! Made it for St. Paddy’s day today and we devoured it. I read the comment about horseradish and added a 1/2 tbsp to our sauce, liked the extra snap. This was such a winner for us, I’m headed to the store in the morning to get a couple more corned beefs to keep in the freezer so we can make it again!
So glad to hear Jeni!
I made this tonight and it’s a recipe I plan on keeping and using again!! My husband was really impressed!! Next time I think I’ll add a little horseradish to the mustard sauce but it was definitely delicious as is!
Glad to hear Joni! Thanks for sharing 🙂

Sounds like a great recipe. However is there any way to bring down the salt content in corned beef? Thanks
Corned beef is just a salt cured beef brisket…so it’s just very salty. If you want to try a regular beef brisket instead that would work or a roast.

You’re right Karen, corned beef is inherently salty but I’m wondering if soaking the corned beef in water for 30 minutes and dumping off the water prior to cooking it could help reduce a bit of the saltiness.
Do you think I could cook double this in a 6 quart crockpot? I am making this for a group at church.
For sure you could double the meat and have room. But I don’t know if you’d have room for doubling all the vegetables too. I guess it depends how big your corned beef briskets are. One option is to cut the corned beef into quarters so that you can fit all the ingredients in.
