Corned Beef Weekend Leftover Ideas 

Reuben Sandwich
Reuben Sandwich for St. Paddy’s Day

St. Patrick’s Day was ushered in quite happily early in the day when Mr. Jack Rabbit himself visited me. He seemed to know the perfect moment to arrive – just as I was preparing the slow cooker corned beef meal with red potatoes and mini cabbages. Maybe the aroma of Brussels sprouts was strong enough to reach his nostrils. Jackrabbits do have a keen sense of smell.

Did you know?

Do you know your Brussels sprouts history? The first written reference of these mini cabbages goes back to 1587. They were probably common way before then. Brussels sprouts grow from a fibrous stalk, unlike cabbage heads that grow out of the ground which we eat. Brussels sprouts grew in Belgium, not in Ireland.

  9. Put the lid on, plug in the slow cooker, turn it on high, and cook for at least 5-1/2 hours (you can cook it for up to 7 hours - the potatoes and Brussels sprouts will be very soft).

  10. Serve with a horseradish sauce or rye bread.

If you have a food processor or vegetable chopper, you can chop the potatoes and onions much easier than with a knife. I chop the veggies the old-fashioned way with a simple knife because it’s quick and I don’t have to deal with using different food processor attachments and blades. However, I do like the Chef’n VeggiChop hand-powered vegetable choppers (that’s on my to-purchase list) – no electricity needed. This little chopper would have come in handy when I lived the RV traveling lifestyle for several years in the past and in a cabin. It would also be perfect for all the tiny-house owners or in small kitchens. A home chef with a small kitchen would appreciate such a small non-electrical vegetable chopper.

Corned beef leftover ideas

  • grilled cheese sandwiches on rye bread: Try it with the Kerrygold Dubliner 100% Natural Cheese (my favorite). It’s imported from Ireland. Dip it in Woeber’s Horseradish Sauce. Mmmm good – that is, if you like sweet & spicy.
  • corned beef & cauliflower hash browns: – This is for the healthy conscious folks. You could make it at least once to see how you like it.
  • make corned beef and potato soup: – The Pioneer Woman’s Perfect Potato Soup really does look perfect and would taste very yummy with corned beef in my opinion.  (cut the corned beef into small chunks and mix in with the potato soup)
  • corned beef omelet: Add some of that Dubliner cheese, and have an Irish omelet for breakfast. Even better, serve the omelet with authentic Irish brown bread.
  • Reuben sandwiches: Make it with or without the sauerkraut.

The slow cooker corned beef meal can be stretched to provide enough leftovers for a few meals if it’s for one or two people. If you’re cooking for two, and especially if you’re bringing the corned beef meal to a potluck, a four-quart slow cooker is great – like this stainless steel “Cook and Carry Slow Cooker” that I would love to have. However, I’ve cooked often in my daughter’s programmable 7-quart slow cooker which works better for more than four servings.

What’s nice about the 7-quart appliance is the warm setting. Make the grilled cheese or Reuben sandwiches and keep them warm in the slow cooker, wrapped in foil (no need to add water for this). You can also cook leftover corned beef and cauliflower hash browns in a slow cooker as well as the corned beef and potato soup.

Got more corned beef leftover ideas and want to share? I’d love to hear about them and try them out.


  1. Maybe, that Jack Rabbit was a scout for the Easter Bunny. He’s reminding us that Easter is just around the corner.
