Corned Beef Cheese Sliders

The kitchen filled with this incredible buttery aroma when I first made these for a Super Bowl party, and honestly, I had to stop people from eating them straight off the baking sheet. Something about that poppy seed crust gets everyone immediately.

My friend Sarah actually asked for the recipe while still chewing her first slider, which I consider the highest possible compliment. Now they are her go to for hosting because they look impressive but take almost no effort.

Ingredients

• 12 slider buns or mini brioche buns: Brioche adds this wonderful sweetness that balances the salty corned beef perfectly
• 400 g (14 oz) cooked corned beef, thinly sliced: Ask your deli counter to slice it paper thin, it makes such a difference in texture
• 12 slices Swiss cheese: Provolone works beautifully too if you prefer something milder
• 3 tbsp Dijon or yellow mustard: Dijon gives that nice tangy bite that cuts through the rich cheese
• 3 tbsp mayonnaise: This prevents the bun from getting soggy while adding creaminess
• 12 small dill pickle slices: These add the perfect acidic crunch that brightens each bite
• 1 small red onion, thinly sliced: Completely optional but I love the sharp bite it brings
• 2 tbsp unsalted butter, melted: Brushing the tops creates that irresistible golden finish
• 1 tsp poppy seeds: These add such a lovely crunch and make them look bakery worthy

Instructions

Preheat your oven to 180°C (350°F):

Line a baking sheet with parchment paper to prevent sticking and make cleanup effortless

Slice your buns horizontally:

Keep the tops connected if you can, it makes assembly faster and keeps everything together

Spread the condiments:

Mix the mayonnaise and mustard together first, then spread on the bottom halves for even flavor distribution

Layer the corned beef:

Do not be afraid to pile it on generously, the buns can handle it and it creates that satisfying heft

Add the cheese slices:

Let the cheese extend slightly over the edges, those crispy melted bits are everyone favorite part

Top with pickles and onion:

Place the pickle slice right in the center so every bite gets that briny crunch

Replace the bun tops:

Gently press down to help everything adhere together before brushing with butter

Brush and sprinkle:

Use a pastry brush to coat every inch of the tops, then shower with poppy seeds for that classic look

Bake covered first:

The foil steams the corned beef and melts the cheese without drying out the buns

Finish uncovered:

Those last 5 minutes create the golden buttery crust that makes these absolutely irresistible

These sliders have become my emergency hosting secret because I can prep everything ahead and just pop them in the oven when guests arrive. The smell alone gets people excited before they even see them.

Make Ahead Magic

I have assembled these the night before and stored them covered in the refrigerator, then just baked them fresh the next day. The buns actually benefit from that rest, absorbing the condiment flavors beautifully.

Cheese Selection

While Swiss cheese provides that classic mild and nutty flavor, sharp cheddar creates this incredible orange drippy cheese situation that photographs beautifully. Havarti melts like a dream if you want something extra creamy.

Serving Suggestions

These sliders work for literally any occasion from casual game day to cocktail parties. They are substantial enough to serve as the main appetizer but light enough that people still have room for other things.

• Cut them with a serrated knife for clean edges that do not squish the toppings
• Use a fresh sharp knife to slice through all the layers in one motion
• Keep them warm in a 150°F oven if not serving immediately

There is something universally satisfying about miniature food, and these sliders hit that perfect balance of nostalgic comfort and impressive presentation.
