French Onion Roast Beef Sliders

Why you'll love my roast beef sliders recipe

• Ultimate Super Bowl party food. Everyone loves a good slider on Hawaiian sweet rolls! Add in some caramelized onions, meat, and cheese, and you have the most perfect slider. They'll steal the show!
• "Secret" ingredient. Because nobody likes a dry slider, I spread the buns with French onion sour cream! It also adds so much flavor!
• Simple and easy. Made with simple ingredients and easy to assemble. Waiting for the onions to caramelize is the most time consuming step, but adding a pinch of sugar and covering with a lid helps to speed up the process!

Ingredients

I'm all about simple ingredients and this recipe is no different!

• Yellow onion.
• Butter.
• Granulated sugar. Optional but it helps to caramelize the onions quicker and adds an extra touch of sweetness.
• Hawaiian sweet rolls. Such as King's Hawaiian.
• French onion sour cream. Such as Old Home French Onion Dip.
• Roast beef. Just the roast beef in the lunchmeat aisle or at the deli counter.
• Provolone cheese. Pre-sliced is quick and easy for this recipe.
• Garlic cloves.
• Fresh parsley.
• Beef broth.
• Red wine. To make a quick and easy au jus for dipping. Use a cheaper medium-bodied red wine like Pinot Noir or a red blend. Alternatively, you can use more beef broth or buy premade au jus from the grocery store.
• Worcestershire sauce.
• Soy sauce.

How to make Hawaiian roll roast beef sliders

These roast beef sliders are so simple to make with deli roast beef, provolone slices, quick caramelized onions, Hawaiian sweet rolls, and my "secret" ingredient French onion sour cream! Here's an overview with some helpful tips.

*Scroll down to the recipe card for the full instructions.

• Step 1: Caramelize the onions. I like to add a little granulated sugar and cover with a lid to speed up the process!
• Step 2: Assemble the sliders. Place the bottom half of the Hawaiian sweet rolls (keeping them all attached) on a sheet pan. Spread with French onion sour cream, then top with roast beef, cheese, caramelized onions, and the top buns.
• Step 3: Brush with garlic herb butter. Mix melted butter, garlic ,and fresh parsley, then spread over the top of the buns. This adds extra flavor and makes the rolls look extra delicious.
• Step 4: Make a simple au jus. Simmer beef broth, red wine, Worcestershire, and soy sauce while the sliders bake. Alternatively, you can buy premade au jus or an au jus packet at the grocery store, but I prefer the homemade version!
• Step 5: Serve and enjoy! Serve the warm and cheesy sliders with au jus for dipping!

Frequently asked questions

What kind of cheese goes with roast beef?

Provolone is a great mild-tasting cheese that pairs well with roast beef and melts great. Swiss, white cheddar, gruyere, or havarti also have mild flavors and work well for roast beef sliders.

What goes with sliders at a party?

Sliders are great served alongside just about any party food, such as chip dip, wings, and meatballs.

• Hot and Cheesy Fried Pickle Dip
• Pretzel Pigs in a Blanket with Beer Cheese Dip
• Air Fryer Hot Honey Butter Chicken Wings (oven option)
• Smoked Queso Dip (crockpot option)
• Bourbon BBQ Bison Meatballs (or beef)

How many sliders per person at a party?

When served alongside other party food, assume most guests will eat 1 slider; however, the occasional guest may have 2 sliders (they're just that good). So I would figure about 1 ½ sliders per guest.

How do you keep sliders warm for a potluck?

I recommend baking the sliders in an aluminum tray then covering them with the lid that comes with the tray or cover tightly with aluminum foil.

How to prevent the bottom buns from getting soggy?

Other than the French onion sour cream, there isn't any other sauce on the buns so this shouldn't be an issue. But for extra security, you can lightly toast the bottom buns in the oven before adding the toppings.

To toast the bottom buns, brush the tops of the bottom buns with melted butter then place in the oven under the broiler. Broil for 1-2 minutes until light golden brown. Watch closely so they don't burn!

Are the sliders still good without the au jus?

YES! These sliders are amazing even without the au jus, and when serving for a party like the Super Bowl, au jus isn't the easiest. So for bigger parties, I say skip the au jus!

Substitutions and variations

• Au jus. My homemade version is super easy to make and honestly better for you than any store-bought au jus, but you can buy premade au jus or an au jus packet at the grocery store if preferred. Or you can skip the au jus altogether. The sliders are still amazing without it.
• Use your favorite deli meat. If roast beef isn't your favorite. Try the slides with ham or turkey!
• Try a different kind of cheese. Swiss, mozzarella or white cheddar would all be great options.

Storing and reheating

If you're planning to transport the slides to a party I recommend baking the sliders in an aluminum foil baking pan. Then to keep them warm, cover with the lid or tightly with aluminum foil.

Store leftover sliders in the fridge for up to 3-4 days. Cover with aluminum foil to reheat in the oven until warm.
