Roast Beef Sliders

Roast Beef Sliders are juicy, savory mini sandwiches perfect for easy parties and casual gatherings. Ready in under 30 minutes, these tender beef sliders are layered with melted cheese, caramelized onions, fresh greens, and a spicy horseradish sauce, making them an irresistible crowd-pleaser that’s both flavorful and fuss-free.

Ingredients

Meat & Protein

  • Roast beef slices – thinly sliced, about 12 oz

Breads & Dairy

  • Slider buns – 12 soft small buns
  • Cheese slices (Swiss or provolone) – 12 slices
  • Butter – 2 tablespoons, melted for toasting

Produce & Vegetables

  • Fresh arugula or lettuce – 1 cup, washed and dried
  • Onions (for caramelized onions) – 2 medium, thinly sliced

Condiments & Sauces

  • Horseradish sauce – 3 tablespoons
  • Olive oil or butter – 1 tablespoon for caramelizing onions

Instructions

  1. Prepare the caramelized onions: Slice the onions thinly and cook them slowly over medium-low heat with a tablespoon of olive oil or butter, stirring occasionally, until they become golden brown and sweet, about 20-25 minutes.
  2. Toast the slider buns: Brush the slider buns with melted butter and toast them in a pan or oven until golden and slightly crispy, enhancing texture and flavor.
  3. Assemble the sliders: Layer a slice of roast beef on each bun bottom, add a slice of cheese, a spoonful of caramelized onions, and a small handful of fresh arugula or lettuce. Spread horseradish sauce on the bun top and close the sandwich.
  4. Final touch and serve: Optionally, secure each slider with a toothpick, arrange them on a platter, and serve immediately while warm and inviting.

Notes

  • Use quality, fresh, thinly sliced deli roast beef for best texture and juiciness.
  • Toasting the buns adds crunch and prevents sogginess from the sauces.
  • Balance flavors by combining sharp cheese with the heat from horseradish sauce.
  • Prepare caramelized onions and sauces ahead to save time during party prep.
  • Keep sliders warm using a low oven heat or warming tray before serving.
