Tender deli French Dip Sliders on soft Hawaiian rolls with melty provolone, sweet caramelized onions, and a buttery onion soup glaze brushed across the top. Served warm with au jus for dipping, ready in 60 minutes.
In a large skillet over medium heat, melt the butter. Add the onions and coat them in the butter. Cook, stirring occasionally, for 12 to 15 minutes until soft and browned but not burnt.
3 tablespoons unsalted butter
Add the thyme, salt, and pepper. Stir to combine, take off the heat, and set aside.
3 tablespoons unsalted butter
Preheat the oven to 350 degrees Fahrenheit. Take the rolls out of the package, keeping them intact. Slice across so you have the tops and bottoms separated. Place the bottoms cut side up into an 11 by 7 baking dish.
Top with half of the cheese. Add the roast beef. Top with the onions, spreading them out. Add the remaining cheese, then place the tops of the rolls back on.
3 tablespoons unsalted butter
In a small bowl, stir together the melted butter and onion soup mix. Brush the mixture across the tops of the rolls for even coverage, or just pour the butter sauce on top.
3 tablespoons unsalted butter
Cover loosely with foil, making sure the foil is not touching the tops of the rolls. Bake for 25 minutes. Remove the foil and bake an additional 5 minutes to brown the rolls.
While the rolls are baking, prepare the au jus per the package directions with the water. Serve the sliders warm with an optional garnish of parsley and a small bowl of au jus on the side for dipping.
3 tablespoons unsalted butter

Notes
Dried herbs can be used in place of fresh, just cut the amount in half.
You can use any slider buns you'd like but sweet rolls are our favorite.
Provolone and mozzarella are our cheeses of choice for this recipe.
The au jus is optional, but just ads that much more flavor when consuming.
