Ingredients Needed

Roast Beef – We used lunch meat for this sliders recipe. But if you happen to have leftover pot roast you can use that instead.

Cheese – Provolone and Swiss cheese are what we used. Feel free to use one type of cheese if you prefer.

Onions – You will sauté the onions on the stovetop to break them down. This adds flavor to the sliders.

Butter – Butter is used for topping buns, cooking with onions and if you choose to make au jus.

Broth and Worcestershire – Worcestershire with butter is what you pour over buns to add flavor and keep them soft. The broth is used for making an optional dipping sauce.

Expert Tips

Cooking down the broth and onions creates a rich au jus sauce for dipping.
Making sure to have butter on all areas of rolls is important. If you don’t it will keep rolls moist and soft. Otherwise it will dry out buns when baked in the oven.
You can double the recipe if you want just use a sheet pan.

Storing Leftovers

Go right ahead and store your leftover roast beef sandwiches in an airtight container. The sandwiches will store for 1-2 days.

You can eat the sandwiches cold or warm them up in the microwave or in the oven. If you reheat in the oven we would cover them with foil to prevent the buns from drying out as they warm up. This will help keep the bread nice and soft.

Practical notes

Can we use packet au jus mix?

If you don’t want to make homemade au jus go right ahead and cook up your usual packet brand. Just follow the directions on the packet.

Can we use a different flavor of cheese?

Go right ahead and swap the cheese with any of your usual blends of cheese or omit the cheese if you want. We did a mix as we found it tasted best.

How do you keep sliders from getting soggy?

You can bake the bottom of your buns for 5 minutes before you pile on the meat and cheese if you want. This will help the bottom of the bun dry up a bit so when the sauce is poured over the buns it won’t sog up the bottom.

What is the best bread for sliders?

Sliders can be Hawaiian rolls, Brioche sliders, and more. You want a light and fluffy roll that can easily slice in half to be filled with meat and cheese and baked.

Ingredients

Makes 12 sandwiches

1 package slider buns, butter or potato style 12 rolls
12-15 Slices Deli Roast Beef
1/2 cup Shredded Swiss Cheese
9 Slices Provolone Cheese
1 stick of butter, 1/2 cup
2 Small Onions or 1 Large Onion, sliced thin
Salt and Pepper, to taste
1 cup Beef Broth, optional
1 Tablespoons Worcestershire Sauce

Equipment

Manual Rotary Cheese Grater
9×13 Casserole Dish

Method

Start by adding 2 tablespoons butter and the sliced onions into a skillet on the stove. Cook on medium heat to soften and turn onions a nice golden color. This takes around 5-10 minutes depending on thickness of sliced onions.
Slice your slider buns in half cutting through the middle to create two "slices" of your slider buns.
Next place your bottom half of the slider rolls in a casserole dish. Then pour the sauteed onions over the rolls spreading evenly.
Then top with the Swiss cheese. You can use shredded Swiss or sliced Swiss if that is what you have.
Top the Swiss cheese with deli Roast beef, and top with the Provolone cheese.
Place your top layer of buns on top.
In a skillet on the stove add your remaining butter and the Worcestershire sauce. Cook for 2 minutes once the butter is fully melted.
Pour the mixture evenly over the buns. Bake in the oven for 20-30 minutes or until the butter mixture absorbs into the rolls.

Au Jus Steps

If you want to make au jus for dipping, reserve 2 tablespoons of the sauteed onions and place them in a pan.
Pour in the beef broth and cook while the roast beef sliders are cooking. You want to bring mixture to a boil, once it boils, lower heat and simmer.
The sauce will begin to reduce to about 1/2. Season with salt and pepper and then use the sauce for dipping your French dip sliders in!

Kitchen notes

Au Jus

The Au Jus is optional, so if you don't plan to make it discard the broth in the recipe. Onion – We recommend using a yellow or white onion. We find the red onions do not cook down the right way, and will leave an off flavor. You can also omit the onions if you don't want them on the sandwiches.
