These corned beef sliders are tiny sandwiches filled with tasty, tender corned beef and tangy mustard, all tucked between soft buns. Perfect for game day or a fun snack!
They’re super easy to make! I love how I can whip them up in no time, and everyone always asks for seconds. Plus, they’re perfect for sharing—if you want to share! 😉
Key Ingredients & Substitutions
Slider Buns: I love using Hawaiian rolls for their sweetness and softness, but you can use any soft dinner rolls if you prefer. Whole wheat or gluten-free rolls can also be a great alternative if you’re looking for something healthier.
Corned Beef: Thinly sliced corned beef is key for these sliders. If you’re looking for a leaner option, consider sliced turkey or roast beef instead. Canned corned beef can work in a pinch but may change the flavor slightly!
Swiss Cheese: Swiss cheese gives a delightful melt and taste, but if you’re not a fan, you can substitute with provolone or even cheddar. Each will bring its own flavor to the sliders!
Dijon Mustard: I find that Dijon adds a nice tang. If you prefer something milder, yellow mustard or even a touch of honey mustard can be good substitutes.
Horseradish: This is optional, but it does add a nice kick! If you want to keep it mild, skip it. You can also use spicy mustard for that same zesty flavor without the strong horseradish taste.
How Do I Properly Layer My Sliders for the Best Flavor?
Layering is crucial for these sliders so each bite is packed with flavor. Here’s how I do it:
- First, spread half of the butter mixture on the bottom buns evenly. This helps keep them moist.
- Next, pile on the sliced corned beef. Aim for even coverage so every slider gets a good amount.!
- Lay the Swiss cheese over and don’t forget optional horseradish if you enjoy a kick.
- Finally, spread the rest of the butter mixture on top before placing on the top buns. This really adds to the flavor and helps crisp them up nicely during baking.
Following these steps makes sure the flavors blend well while keeping everything delicious! Enjoy your sliders!

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and around 20 minutes to bake. So, in total, you’re looking at about 30 minutes before those tasty sliders are ready on your table!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This way, it will be nice and hot when your sliders are ready to bake!
2. Prepare the Buns:
Take your slider buns and slice them horizontally. Keep them attached if they come in a connected batch, so they hold together nicely.
3. Make the Butter Mixture:
In a small bowl, mix the melted butter, Dijon mustard, mayonnaise, garlic powder, and onion powder until everything is well combined. This mixture is going to add loads of flavor to your sliders!
4. Spread the Mixture:
Spread half of the butter mixture generously on the bottom half of the buns. This will keep them moist and flavorful!
5. Layer the Corned Beef:
Evenly layer the sliced corned beef over the bottom buns, making sure each slider gets a good amount of beef.
6. Add Cheese and Horseradish:
Place half slices of Swiss cheese on top of the corned beef. If you’re feeling adventurous, add horseradish for a little extra kick!
7. Top it Off:
Spread the remaining butter mixture on the top half of the buns, then place them over the sliders to create little sandwiches.
8. Bake the Sliders:
Loosely cover the sliders with aluminum foil and bake in the preheated oven for about 15 minutes, until the cheese is melted and the sliders are warmed through.
9. Crisp the Tops:
Remove the foil and bake for an additional 2-3 minutes. This will lightly brown the tops and make them deliciously crispy!
10. Garnish and Serve:
Before serving, sprinkle chopped fresh parsley on top for a nice touch! Serve warm and enjoy your flavorful Corned Beef Sliders!
Can I Use Different Types of Cheese?

How Do I Store Leftover Sliders?
To store leftovers, place the sliders 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, or in the microwave for a quick warm-up!
Can I Make These Sliders Ahead of Time?
Yes! You can prepare the sliders up to the baking step, cover them tightly with foil, and refrigerate them for up to 24 hours. When you’re ready to bake, just pop them in the oven and adjust the baking time if needed!
