These corned beef sliders are mini sandwiches packed with delicious flavor! With tender corned beef, melted cheese, and a soft bun, they are super easy to make and taste amazing.
Perfect for parties or a cozy night in, I’ve been known to eat a few more than I planned. They’re so good you won’t want to share! Just bake them and watch them disappear!
Key Ingredients & Substitutions
Slider Buns: Soft dinner rolls are perfect for these sliders. If you can’t find slider buns, you can use regular burger buns or even mini bagels for a fun twist.
Corned Beef: Traditional, but if you’re looking for a lighter version, try using pastrami or turkey for a delicious alternative. Both add great flavor!
Swiss Cheese: The classic choice, but feel free to swap for provolone or cheddar if you prefer. Provolone has a similar flavor, while cheddar adds a bit of sharpness.
Mayonnaise Mixture: The mayo base is creamy and tangy! If you’re avoiding mayo, try using Greek yogurt for a healthier option, or a vegan mayo if needed.
Poppy Seeds: Optional but nice for a little crunch. If you don’t have them on hand, sesame seeds are a great substitute.
How Do You Make the Perfect Sauce for Your Sliders?
The sauce adds real flavor to your sliders, so pay attention here! Mixing the mayo, mustard, horseradish, Worcestershire sauce, garlic powder, salt, and pepper creates a tasty spread. Here’s how to get it just right:
- Start with good-quality mayonnaise for a creamy texture.
- Adjust the amount of horseradish to your taste – add more for extra kick!
- Mix the ingredients well until they’re fully combined. You can even make this ahead for a stronger flavor.
Remember to taste your sauce before spreading it to ensure it has the flavor you love!

This recipe takes about 10 minutes to prepare and around 20 minutes to bake, so you can have these tasty sliders ready in about 30 minutes total! Perfect for a quick snack, party, or game day treat!
Step-by-Step Instructions:
1. Preheat Your Oven:
Start by preheating your oven to 350°F (175°C). This is important to ensure that your sliders bake evenly and the cheese gets nice and melty!
2. Prepare the Sauce:
In a small bowl, mix together the mayonnaise, Dijon mustard, horseradish sauce, Worcestershire sauce, garlic powder, and a pinch of salt and pepper. Stir well until you have a smooth, creamy sauce that will add flavor to your sliders.
3. Slice the Buns:
Carefully slice the slider buns horizontally in half, keeping them attached at the seams if possible. This makes assembly easier!
4. Spread the Sauce:
Take the bottom half of the buns and spread a generous layer of the sauce you prepared earlier. Make sure it’s evenly coated to add flavor to every bite!
5. Layer the Corned Beef:
Next, evenly layer the sliced or shredded corned beef over the sauce. Press it down gently to make sure it stays put.
6. Add the Cheese:
Now, add a layer of Swiss cheese on top of the corned beef. This will melt beautifully when baked!
7. Top It Off:
Place the top half of the buns over the cheese, creating your sliders. It should look like a delicious little sandwich!
8. Butter the Buns:
Brush the melted butter generously over the top of the buns to give them a lovely golden color and flavor as they bake.
9. Optional Garnish:
If you like, sprinkle some poppy seeds and a little chopped chives on top for an extra touch!
10. Bake the Sliders:
Place the assembled sliders in a baking dish and cover them loosely with foil. Bake in the preheated oven for about 15-20 minutes, or until the cheese is melted and the sliders are heated through.
11. Brown the Buns:
Remove the foil in the last 5 minutes of baking to allow the tops of the buns to brown slightly for a delicious finish.
12. Slice and Serve:
Once finished baking, take the sliders out of the oven and cut between the buns to separate them. Garnish with more chopped chives if you like!
13. Enjoy!
Serve your warm corned beef sliders to friends and family, and enjoy a tasty treat you’ll all love!
Can I Use Different Meats for This Recipe?
Absolutely! While corned beef is traditional, you can substitute it with pastrami, turkey, or even grilled vegetables for a vegetarian option. Each meat will bring a unique flavor to your sliders!
How Do I Store Leftover Sliders?
To keep your sliders fresh, store any leftovers in an airtight container in the fridge for up to 3 days. You can reheat them in the oven at 350°F (175°C) for about 10 minutes to restore their deliciousness.
Can I Make the Sauce Ahead of Time?
Yes, you can prepare the sauce a day or two in advance and store it in the refrigerator in an airtight container. Just give it a good stir before using it to spread on your sliders!
What If I Don’t Have Poppy Seeds?
No problem! Poppy seeds are optional. You can substitute them with sesame seeds, or simply leave them off altogether. The sliders will still taste fantastic!
