Servings 6


  • 4 Tablespoons unsalted butter divided
  • 1 Tablespoon olive oil
  • 1 Pound mixed mushrooms sliced
  • 1 Large shallot thinly sliced
  • 2 Cloves garlic minced
  • 2-3 Sprigs thyme, about 1 teaspoon chopped
  • ½ Teaspoon kosher salt
  • 1 Teaspoon worcestershire
  • 1 Cup gruyère grated
  • 1 Cup fontina grated
  • 1 Package savory slider rolls 12 count

For the topping

  • 2 Tablespoons unsalted butter melted
  • 3 Tablespoons Parmigiano Reggiano
  • ¼ Teaspoon garlic powder
  • ¼ Teaspoon kosher salt


  • Pre heat oven to 350 degrees.
  • In a large skillet over medium heat, heat the olive oil and 2 tablespoons of the butter. Add the mushrooms and cook, stirring occasionally, until golden brown. About 5 minutes.
  • Add the remaining 2 tablespoons of butter along with the shallots, garlic and thyme. Stir and cook until the shallots have softened, about 3 minutes. Add the salt and worcestershire and cook for another 3 minutes or until well combined.
  • Meanwhile, make the topping for the rolls. Put the butter in a small bowl and microwave until melted. Add the Parmigiano Reggiano, garlic powder and kosher salt. Stir to combine.
  • Cut the slider rolls in half, separating the top and the bottom. Place the bottoms in a parchment lined baking pan. Layer half of the cheese, then the mushroom mixture, then the other half of the cheese and cover with the top of the rolls.
  • Brush the tops with the melted butter mixture and bake for 12-15 minutes, until the buns are golden brown and the cheese has melted. Following the lines of the rolls, cut into individual sliders.
  • Enjoy!
