Instructions

Preheat oven to 350°F and coat a 13- x 9-inch baking dish with cooking spray.
Using a serrated knife, slice the rolls horizontally and place the bottom half in the baking dish.
Melt 1 tablespoon butter in a skillet over medium-high heat. Add onions and cook for 2 minutes. Lower heat and continue cooking until golden brown, about 15 minutes. Set aside.
Layer roast beef over the bottom rolls, then top with provolone cheese and caramelized onions. Place the top rolls on.
In a small saucepan, melt 4 tablespoons butter with brown sugar over low heat until dissolved. Remove from heat and whisk in mustard and salt. Brush mixture over the top of the rolls and sprinkle with 1 teaspoon thyme.
Cover with foil and bake for 10 minutes. Remove foil and bake another 10 minutes until golden and melty.
While baking, melt the remaining 1 tablespoon butter in a saucepan over medium heat. Add garlic and cook until fragrant. Stir in beef broth, Worcestershire, and remaining thyme. Simmer until slightly reduced, about 10 minutes.
Serve sliders hot with au jus for dipping.

Notes

Add jalapeños or hot sauce for a spicy twist.
Substitute roast beef with grilled vegetables for a vegetarian version.
Try Swiss or cheddar cheese instead of provolone for a different flavor.
Spread horseradish on the rolls for added zing.
Store leftovers in an airtight container in the fridge for up to 4 days or freeze for up to a month.
