  • 3 pounds ground beef
  • salt and pepper to taste
  • 8 ounce sliced mushrooms
  • 1 tablespoon unsalted butter
  • 6 ounce block swiss cheese
  • 12 soft slider buns
  • 1/4 cup mayonnaise
  • 2 teaspoons Dijon mustard



  1. Preheat oven to 400°. Cut or separate top and bottom of slider buns. Place 12 bottom buns on separate sheet pan.
  2. Spread the ground beef evenly out onto a 13 x 18 rimmed sheet pan, covering the entire pan. Sprinkle with salt and pepper.
  3. Place on the middle rack of oven and bake for 20 minutes.
  4. Meanwhile, melt butter in a skillet over medium-high heat. Add sliced mushrooms to melted butter and saute until mushroom are tender. Set aside.
  5. When ground beef is cooked, remove from oven and pour fat off the pan. *Ground beef will shrink so this is normal.
  6. Using a pizza wheel or sharp knife, cut the cooked beef into 12 even squares. Place one square onto each bun bottom on prepared pan.
  7. Top each beef  square with 2 slices of swiss cheese. Place the pan back in the oven for a few minutes to melt the cheese. Remove pan from oven.
  8. Divide the cooked mushroom evenly on top of the melted cheese on sliders.
  9. In a small bowl, combine the mayonnaise with Dijon mustard. Place a teaspoon of mayonnaise on each top bun and place on sliders.
  10. Return sliders to the oven for a few minutes to heat the top bun.
  11. Remove from the oven and serve hot.



Amount that ground beef will shrink depends on the percentage of fat in the mix. I recommend using 80% or better to reduce shrinkage for this recipe.
