Ingredients
Rolls and Fillings
- 1 package King’s Hawaiian Savory Butter Rolls (yellow banner on package)
- 1/4 cup mayonnaise
- 1 tablespoon cream-style horseradish (Inglehoffer recommended)
- 1/2 pound provolone or Swiss cheese, thinly sliced
- 1/2 pound deli roast beef, thinly sliced
- 1/2 cup caramelized onions
Butter Sauce for Rolls
- 4 tablespoons unsalted butter, melted
- 1 teaspoon Worcestershire sauce
- 1/2 teaspoon onion powder
- 1/4 teaspoon garlic powder
- 1/2 tablespoon chopped fresh flat-leaf parsley, plus additional for garnish
Beef Jus
- 2 cups beef broth or stock
- 2 tablespoons unsalted butter
- 1 large garlic clove, minced
- 1 1/2 tablespoons all purpose flour (optional)
- 1 tablespoon Worcestershire sauce
- 1-2 teaspoons Better Than Bouillon Reduced Sodium Roasted Beef Base (optional, to taste)
- 1 teaspoon fresh thyme (or 1/4 teaspoon dried)
- Kosher salt and freshly-ground black pepper (about 1/4 teaspoon black pepper added to jus)
Instructions
- Prep the Rolls: Use a serrated bread knife to slice the King’s Hawaiian rolls horizontally into top and bottom halves. Place them cut side up on a baking sheet.
- Toast the Rolls: Preheat your oven’s broiler on high with the rack about 6 inches from the element. Broil the roll halves until lightly toasted, about 1-2 minutes. Watch carefully to avoid burning.
- Prepare Oven and Baking Dish: Preheat oven to 350°F and lightly coat a 10.5×7.5-inch rectangular ceramic or glass baking dish with cooking spray. Place the bottom halves of rolls toasted side up into the dish.
- Make Horseradish Mayo: In a small bowl, combine mayonnaise and cream-style horseradish. Spread half the mixture over the bottom halves of the rolls.
- Layer Sliders: Add half of the cheese evenly on top of the horseradish mayo, then layer all the roast beef slices, followed by the caramelized onions and remaining cheese. Spread the rest of the horseradish mayo on the toasted side of the roll tops and place them over the cheese layer.
- Brush Rolls with Butter Sauce: In a small bowl, mix melted butter, Worcestershire sauce, garlic powder, onion powder, and chopped parsley. Brush this butter sauce generously over tops and sides of the sliders, allowing excess to drip into the baking dish around the rolls. Sprinkle additional parsley on top.
- Bake the Sliders: Cover the baking dish with foil and bake for 20 minutes until heated through and cheese melts. Remove foil and bake an additional 5-8 minutes until tops are golden and crisp.
- Rest and Slice: Let sliders stand a few minutes, then cut into individual servings using a serrated knife. Garnish with extra parsley if desired. Serve warm with jus for dipping.
- Make the Jus: While sliders bake, melt butter in a medium saucepan over medium heat. Add minced garlic and cook, stirring, for 1-2 minutes until fragrant.
- Thicken the Jus: Stir in flour and cook an additional 1-2 minutes, stirring constantly to form a roux.
- Add Broth and Seasonings: Gradually whisk in the beef broth, Worcestershire sauce, thyme, and 1/4 teaspoon black pepper. Bring to a boil, then reduce heat and simmer for 10 minutes, stirring occasionally.
- Adjust Flavor: Taste the jus and add 1-2 teaspoons of beef base if needed for more flavor. Season with salt and pepper to taste.
- Strain and Serve Jus: Strain jus through a fine mesh sieve to remove solids. Keep warm and serve in small cups alongside sliders for dipping.
Notes
- For best flavor, use freshly caramelized onions or store-bought caramelized onions of good quality.
- If you prefer a thicker jus, use the optional flour to create a roux before adding broth.
- Better Than Bouillon Reduced Sodium Roasted Beef Base is optional and can be adjusted based on the richness of your beef broth.
- Watch the rolls closely during broiling; they can burn very quickly due to high heat.
- Slide assembly can be customized with Swiss cheese or other cheese varieties depending on preference.
