Happy St. Patrick’s Day! Even during challenging times, a small celebration at the table can bring comfort. I regularly make a traditional Irish meal—corned beef and cabbage with Irish soda bread—and the next day I transform the leftovers into these easy sliders. They’re always the family favorite and perfect for casual entertaining.

How to make this recipe

This recipe is straightforward and forgiving. You can cook the corned beef in a slow cooker or pressure cooker, prepare the coleslaw ahead of time, and assemble the sliders quickly when you’re ready.

  • Cook the corned beef: Braise the brisket with Guinness, water, brown sugar and sliced onion, along with the seasoning packet included with the corned beef. Cook until fork-tender in the Instant Pot or slow cooker, then rest 10 minutes and slice thinly against the grain.
  • Make the coleslaw: Use a prepackaged coleslaw blend or shredded cabbage and toss with a creamy, no-mayo dressing or your favorite slaw dressing. Keep the slaw chilled and toss with dressing just before assembling to preserve crunch.
  • Assemble the sliders: Layer corned beef slices on the bottom roll, add a generous scoop of coleslaw, and spread whole grain mustard or prepared horseradish on the top roll. Secure with a toothpick if desired and serve immediately.

How to serve corned beef sliders

Serve sliders as an appetizer, casual main, or at a party. Complement them with hearty sides for a fuller meal:

  • Crispy smashed baby potatoes
  • Roasted carrots and parsnips
  • Garlic Yukon Gold mashed potatoes
  • A simple green salad or pickles to cut the richness

Recipe notes

  • Corned beef can be cooked up to a day ahead and gently reheated before slicing and assembling.
  • Prepare coleslaw in advance but toss with dressing right before serving to keep it crisp.
  • To make gluten-free sliders, replace the Guinness with water when braising and choose gluten-free slider rolls.
  • Try different spreads—Dijon mustard, horseradish cream, or a tangy aioli all pair well.

Ingredients

For the corned beef:

  • 1 pint Guinness beer (or substitute water for gluten-free)

  1. Combine the Guinness (or water), water, and brown sugar in the pot. Add the sliced onion, then place the corned beef in the liquid and add the spice packet.
  2. Cook the brisket in the Instant Pot or slow cooker according to your appliance instructions until tender, about 8–10 hours on low in a slow cooker.
  3. Once cooked, let the corned beef rest for 10 minutes, then slice thinly against the grain.
