The party food to beat all party foods! If you’re feeding a crowd these roast beef sliders are much easier to make than you might think! Slice it thin and pile it high!
Make sure your top round roast is prepared for roasting by tying it tightly with butcher’s twine (a good butcher will do this for you if you mention you are making roast beef). Also season the roast with salt and pepper generously in advance if you can (overnight is good).
Preheat oven to 375 degrees F. Place prepared roast in a roasting pan or I like to cook in on a wire rack so the heat can circulate around the meat.
Roast beef for 20 minutes and then reduce heat to 250 degrees F. Continue to roast until the beef reaches an internal temperature of 135 degrees F. in the thickest part of the roast. The ONLY way to know this with accuracy is to use a meat thermometer. Don’t eyeball it!
Remove roast and let it rest for 15 minutes. Then slice it very thin with a carving knife.
Serve roast beef slices on slider buns with toppings.
For horseradish mayo, mix 1 cup of mayonnaise with 3-4 tablespoons spicy Horseradish.
