Ingredients

12 Hawaiian slider rolls still connected
6 tablespoons butter melted (divided) and more for toasting
1 small sweet onion sliced thin, or white or yellow onion
1 teaspoon salt
½ teaspoon pepper
1 teaspoon Italian seasoning
1 ½ pounds deli sliced roast beef
9 slices provolone cheese or more if desired
2 tablespoons dry onion soup mix
1 pkt (1 oz) au jus gravy mix
3 cups water
2 tablespoons parsley chopped

Instructions

Preheat your oven to 350 degrees and spray an 9 x13 casserole dish lightly with nonstick spray.
Slice and place the bottom half of your sliders into the bottom of your casserole dish. Brush with some more melted butter and bake for 5 minutes and set aside.
In a large heavy-bottom non-stick skillet, melt 3 tablespoons of butter over medium heat. Add the onion slices to the butter and then sauté the onions over medium heat until brown but not burnt. Do this by flipping and stirring the onion slices in the butter for about 10 minutes. Add the salt, pepper, and Italian seasoning, and stir well. Set aside.
Layer your ingredients over the bottom buns, starting with the roast beef slices, then your sauteed onions, then provolone slices, and finally place the bun tops on last.
In a small bowl, combine the remaining 3 tablespoons of your melted butter with the onion soup mix and brush it over the bun tops. Make sure the onion pieces lie on top of the buns for the best flavor.
Bake in your preheated oven uncovered for 15-20 minutes or until the tops are toasted and the sliders are heated throughout, and the cheese is melted.
While your sliders are baking, use a small heavy-bottom non-stick skillet to bring the water and au jus gravy mix to a light simmer and whisk until well combined. Set aside until the sliders are ready.
Once the sliders are ready, sprinkle with chopped parsley, slice the sliders and serve! Use the au jus gravy for dipping.

Notes

Build the best flavor: Slowly caramelize the onions, use quality deli roast beef, and don't skip the au jus for that classic French dip taste.
Assemble for success: Toast the bottom buns to prevent sogginess and then add cheese. Layer cheese above the beef and onions to help hold everything together.
Bake to perfection: Brush the buns evenly with the butter mixture and bake until the sliders are heated through and the cheese is completely melted.
Serve hot and ready: French Dip Sliders are best enjoyed fresh from the oven, and making extra au jus ensures plenty for dipping.
