Notes
Double: Double the beef sliders recipe for a large party or game.
Spice it Up: Add a sprinkle of red pepper flakes or hot sauce to the sauce for a fiery kick.
Go Veggie: Toppings like caramelized onions, roasted peppers, or even sautéed mushrooms for a vegetarian twist.
Cheese Medley: Don't limit yourself to one cheese! Mix and match different varieties for this easy weeknight meal. Sprinkle in Cheddar, American or Mozzarella for the baked roast beef sliders.
