Easy French Dip Sliders Recipe (VIDEO)

French Dip Sliders with tender pastrami beef, melty provolone, and caramelized onion on a soft toasted sweet roll. Like our Cheeseburger sliders, these sliders are a fun and easy way to feed a crowd. These come together quickly and you’ll love the easy au jus dipping sauce.

We love warm homemade sandwiches, from juicy Smashburgers to crispy Chicken Sandwiches and gooey Grilled Cheese. As a child, I never liked cold sandwiches, but give me all the warm ones because they remind me of restaurant sandwiches.

These French Dip Sliders are very satisfying and leftovers reheat well. You can also scale down the recipe easily for a smaller batch- sometimes the buns come in packs of 12 and that’s ok. My son loves these as an afterschool power snack.

What are Sliders?

We translate our videos into many different languages and the word slider translates in the funniest ways. In Ukrainian, it translates to ‘povsoonky’ or a baby’s onesie. Actually, sliders are simply small-sized burgers or warm sandwiches made with a soft bun.

Ingredients for French Dip Sliders

• Beef – deli-sliced pastrami (what we used here), thinly sliced roast beef or even corned beef would work great for these.
• Cheese – we used a mild provolone. Avoid aged provolone since it adds weird flavors unless you like that sort of thing. You can also substitute with sliced mozzarella which melts beautifully.
• Buns – we used Hawaiian sweet rolls. I purchased the larger 16 count packs at Costco, but you can use the 12-count packs and put them side-by-side or scale down the recipe.
• Mayonnaise – adds moisture to the buns so they don’t get dry.
• Butter – adds moisture and flavor to the buns.
• Sesame Seeds – make the buns look cuter. You can skip them if you don’t have them on hand.
• Onion – yellow onion works well here. Use 1 large onion or 2 smaller ones. We add a sprinkle of sugar to caramelize onions faster. Keep in mind the onion shrinks up as it caramelizes.
• Au Jus Seasoning – this is a store-bought seasoning mix but you can also make your own (see note below).

How to Make Pastrami Sliders

1. Saute onions – Heat olive oil and butter over medium/high heat. Add onions and saute 5 mintues. Sprinkle with 1/4 tsp sugar and saute another 5 minutes to caramelize. Transfer to a plate.
2. Cut Buns – use a serrated knife to slice buns in half, cutting all the way through the layer to make top buns and bottom buns.
3. Add toppings– spread mayo over the bottom buns then top with layers of pastrami and spread onions over the top. Add sliced provolone.
4. Add top buns – place the top buns over the cheese and brush the top generously with melted butter. Immediately sprinkle with sesame seeds or layer pastrami in ribbons over the bottom buns and bake uncovered.
5. Make sauce – in the same skillet that onions were cooked, add water to deglaze the pan and make the au jus according to the package instructions (add the mix to taste since it can get salty).

Pro Tip: If you don’t have sesame seeds on hand, you can also use Everything Bagel seasoning to sprinkle the tops before baking.

The best sauce for French Dip Sandwiches

Ideally, if you made roast beef, prime rib, or a pot roast yourself, you can use the pan drippings to create a lovely au jus dipping sauce. Since we’re using store-bought deli meat (a quick and easy substitute), we used a store-bought au jus seasoning mix. Au jus mix is pretty salty when made to the packet instructions so add the seasoning or water to taste.

You can also reduce down beef broth and create your own in the onion pan as we did with our Classic French Dip Sandwich Recipe.

Serve with

Sliders are unique in that they can be served as an appetizer (think Game Day!) or the main course. We love it as a main course paired with:

• Potato Wedges
• Sweet Potato Fries
• Corn on the Cob
• Caesar Salad
• Air Fryer French Fries

French Dip Sliders are great as an easy dinner or a party appetizer. These disappear fast and that cheese pull is irresistible.
