These corned beef sliders are tiny sandwiches packed with flavor! With tender corned beef and melty cheese between soft buns, they make a perfect snack or meal.
Honestly, how can you resist those little bites? I love making these for game nights – they disappear faster than I can make them! 😂 Just pop them in the oven and enjoy!
Key Ingredients & Substitutions
Slider Buns: Soft, slightly sweet buns are perfect for these sliders. If you can’t find slider buns, mini brioche or even dinner rolls will work. Just make sure they’re not too crusty, so they stay soft!
Corned Beef: Thinly sliced corned beef is the star here. You can substitute with pastrami if you want a bit more spice, or even use turkey or chicken for a lighter option. Just keep the slices thin for easy biting!
Swiss Cheese: While Swiss cheese gives a nice flavor, you can swap it for provolone or even cheddar if you’re a fan! I personally love a blend of cheeses for extra zest.
Mayonnaise: The mayo-mustard mix keeps the buns moist. If you’re looking for a lighter option, try Greek yogurt mixed with the mustard instead. It adds creaminess without the extra calories.
How Can I Make Sure My Sliders Are Just Right?
Making sliders is easy, but there are a few tricks to get them just right! Start by layering ingredients evenly. This will ensure each bite is packed with flavor.
- Preheat your oven and watch the timing: bake covered to keep moisture, then uncover to crisp up!
- Don’t rush the baking process; letting the cheese melt and the tops brown properly makes a big difference in texture.
- As a finishing touch, let them cool a minute after baking before serving. It makes them easier to handle!

Ingredients You’ll Need:
For the Sliders:
- 12 slider buns (preferably soft and slightly sweet)
- 1 pound corned beef, thinly sliced
- 12 slices Swiss cheese (or more, depending on preference)
For the Dressing:
- 1/2 cup mayonnaise

- 1 tablespoon horseradish (optional, for extra kick)
For the Topping:
- 2 tablespoons butter, melted
- 1 tablespoon poppy seeds
- 1 teaspoon garlic powder

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and 20 minutes to bake. So, you’re looking at a total time of about 30 minutes before you dig into these delicious sliders!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This will make sure it’s hot enough to melt the cheese nicely when your sliders go in!
2. Prepare the Buns:
Carefully slice the slider buns in half horizontally. Place the bottom halves on a baking dish or a baking sheet. This will create a nice base for your tasty fillings.
3. Make the Mayo-Mustard Mixture:
In a small bowl, mix the mayonnaise, Dijon mustard, and horseradish, if you’re using it, until they are well combined. This tasty spread will add a fantastic flavor to your sliders!
4. Assemble the Sliders:
Spread a generous layer of the mayo-mustard mixture over each bottom bun half. Then, layer on the sliced corned beef evenly across the spread. Place a slice of Swiss cheese on top of the corned beef for that melty goodness.
5. Cover with the Top Buns:
Now, gently place the top halves of the buns over the cheese. This completes your slider assembly!
6. Prepare the Butter Mixture:
In a separate small bowl, combine the melted butter with the poppy seeds, garlic powder, and onion powder. This mixture will give a lovely buttery flavor and a nice finish to your sliders.
7. Brush and Bake:
Brush the butter mixture generously over the tops of the buns. Then, cover the sliders loosely with aluminum foil to keep them moist while baking. Bake in the preheated oven for about 15 minutes, or until the cheese is melted and the filling is warmed through.
8. Crisp Up:
After 15 minutes, carefully remove the foil and bake for an additional 5 minutes. This will allow the tops to crisp up nicely.
9. Serve and Enjoy:
Once done, take your sliders out of the oven and let them cool for a minute. Serve warm and enjoy your delicious corned beef sliders! Perfect as party appetizers or a tasty snack!
Can I Use Different Types of Cheese?
Absolutely! While Swiss cheese is traditional, you can substitute it with provolone, cheddar, or even pepper jack for a little heat. Just choose your favorite for a delicious twist!
How Do I Store Leftover Sliders?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm them in the oven at 350°F (175°C) for about 10 minutes, or until heated through.
Can I Make the Sliders Ahead of Time?
Yes! You can prepare the sliders up to assembling them (steps 1-6), cover them tightly, and refrigerate for a few hours or overnight. Just brush with the butter mixture before baking when you’re ready to serve!
What Can I Serve with Corned Beef Sliders?
These sliders pair well with a variety of sides! Consider serving them with chips, pickles, or a fresh salad to balance the richness. They’re also great alongside beer or a hearty stout!
