Equipment
- Large Skillet
- Baking Dish
- Mixing Bowl
Ingredients
- 2 Tbsp. unsalted butter softened
- 1 Tbsp. olive oil
- 1-2 pieces sweet onions thinly sliced
- 1 package Hawaiian sweet rolls (12 rolls total)
- 1 lb. sliced deli roast beef
- 10 slices provolone cheese separated
- ½ cup unsalted butter melted
- 2 Tbsp. brown sugar
- 1 Tbsp. Dijon mustard
- 1½ Tbsp. Worcestershire sauce
- ½ tsp. garlic powder
- ¼ tsp. onion powder
- ½ tsp. dried thyme
- au jus dipping sauce for serving
- horseradish for serving
Instructions
- Preheat your oven to 350°F (175°C). Lightly spray a 9x13 inch baking dish with cooking spray.
- In a large skillet, combine the softened butter and olive oil. Add the sliced onions and sprinkle with salt. Sauté for 15-30 minutes until caramelized.
- Without separating them, slice the Hawaiian rolls in half horizontally. Place the bottom half in the prepared baking dish.
- Layer the sliced roast beef over the rolls, followed by provolone cheese and caramelized onions. Place the top half of the rolls over the assembled ingredients.
- In a bowl, whisk together the melted butter, brown sugar, Dijon mustard, Worcestershire sauce, garlic powder, onion powder, and dried thyme. Pour the mixture over the top of the rolls.
- Cover with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 7-10 minutes until the tops are lightly browned and the cheese is bubbling.
- Let cool slightly, then cut along the lines to separate each slider. Serve warm with au jus and horseradish.
