French Onion Roast Beef Sliders
These French Onion Roast Beef Sliders are a deliciously savory twist on the classic sandwich, made with caramelized onions, provolone, and a flavorful au jus for dipping. Perfect for parties or weeknight dinners!
Ingredients
Sliders
- 1 large yellow onion thinly sliced
- 5 tablespoons butter divided
- 1/4 teaspoon sugar
- 12 hawaiian sweet roll slider buns
- 1/2 cup French onion sour cream dip
- 1 pound deli roast beef
- 10 slices provolone cheese
- 2 cloves garlic minced
- 1 tablespoon parsley finely chopped
Au Jus
- 1 cup beef broth
- 1/4 cup red wine
- 1 tablespoon Worcestershire sauce
- 1 tablespoon soy sauce
Instructions
- Preheat oven to 350° F.
- Melt 3 tablespoons butter in a skillet over medium heat. Add the onions and sprinkle with sugar. Cover and cook until caramelized, stirring occasionally, about 15-20 minutes. Turn down the heat if the onions start to burn.
- Meanwhile, cut the buns in half lengthwise, leaving them all attached, and place onto a parchment-lined baking sheet. Spread the bottom buns with French onion sour cream dip, then top with roast beef, cheese, and caramelized onions. Cover with the top buns.
- Melt 2 tablespoons butter and mix with garlic and parsley. Brush or drizzle over the top buns.
- Bake for 10-15 minutes or until the cheese is melted. If the buns are browning too fast, loosely cover them with aluminum foil.
- Meanwhile, make the au jus. Add all the ingredients to a small pot and simmer on low for 10 minutes.
- Serve the sliders with au jus for dipping!
Notes
These sliders are easy to customize—swap the cheese, try horseradish mayo instead of sour cream dip, or add a touch of mustard for extra zing.
