Corned Beef Sliders Mustard

The first time I made these sliders was for a Super Bowl gathering where I completely underestimated how quickly they would disappear. Between the first and second quarters, the platter was empty and people were actually asking if there were more hiding somewhere in the kitchen.

Last winter my neighbor smelled these baking through our shared wall and showed up with an empty plate, asking if whatever I was making had been an accident or on purpose. Now she texts me every time she knows I am planning slider night.

Ingredients

• Cooked corned beef: Thinly sliced corned beef works best here and buying it pre cooked from the deli counter saves you hours
• Slider buns: Brioche or potato rolls hold up beautifully without getting soggy and add just the right sweetness
• Mustard: Yellow mustard brings the classic tang but Dijon adds sophistication if you are feeling fancy
• Dill pickles: These provide the crucial crunch that cuts through all that rich beef and cheese
• Swiss cheese: The nutty mildness pairs perfectly with corned beef though cheddar works if you prefer sharper flavors
• Butter mixture: This garlic butter brush is what transforms good sliders into something people cannot stop talking about

Instructions

Prep your station:

Preheat your oven to 180°C (350°F) and slice your slider buns horizontally if they did not come that way

Build the foundation:

Arrange the bottom halves of your buns on a parchment lined baking sheet ready for the good stuff

Layer the goodness:

Distribute your corned beef evenly across all the buns then add half a slice of Swiss cheese to each if you are going that route

Add the crunch:

Top each slider with a dill pickle slice because texture contrast makes everything better

Close them up:

Spread mustard generously on the top buns then place them on their bases to complete the assembly

Make them shine:

Whisk together the melted butter garlic powder and poppy seeds then brush this mixture over every top bun

Bake to perfection:

Cover loosely with foil and bake for 8 to 10 minutes until the cheese is melted and everything is warmed through

Serve them up:

Remove from the oven uncover and get these to the table while they are still hot and aromatic

Save

My brother in law who claims he does not even like corned beef ate four of these at a family picnic last summer then asked for the recipe before he even left the parking lot.

Make Ahead Magic

You can assemble these sliders up to 24 hours in advance and keep them covered in the refrigerator. Just add the butter mixture right before baking so the buns do not get soggy overnight.

Perfect Pairings

These sliders shine alongside simple potato chips a crisp coleslaw or even just some raw vegetable sticks to balance all the richness. A cold beer or sparkling water with lemon completes the experience perfectly.

Serving Crowd Size

For a big party double or triple the recipe and use multiple baking sheets. These reheat surprisingly well so making extras is never a bad idea.

• Cut the finished sliders with a sharp knife to keep everything tidy
• Have extra mustard on the table for people who like it really tangy
• These transport well if you are heading to a potluck

Save

There is something deeply satisfying about serving food that makes people pause between bites and genuinely ask what you put in them to make them taste so special.
