Ingredients
- 12 slider buns soft ones like King’s Hawaiian work great
- 1 lb sliced roast beef deli-style or leftovers
- 6 slices provolone cheese or Swiss if you prefer
- 1 large onion sliced thin (optional but adds great flavor)
- 2 tablespoons butter
- 1 packet au jus mix or homemade if you like
- 1 ½ cups beef broth
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 tablespoon Dijon mustard for butter topping
- 1 tablespoon melted butter to brush on top
Instructions
- Prep the oven
- Preheat your oven to 350°F (175°C). Line a baking dish with parchment paper or lightly grease it.
- Slice the buns
- Slice the slider buns in half horizontally. Place the bottom halves into the baking dish, cut side up.
- Layer it up
- Evenly layer the sliced roast beef over the bottom buns. Top with provolone cheese slices. Add cooked onions if using.
- Add the tops
- Place the top halves of the buns on top of the meat and cheese layers.
- Make the butter topping
- In a small bowl, mix melted butter, Dijon mustard, garlic powder, and a little Worcestershire sauce. Brush this mix over the top of the buns.
- Bake
- Cover with foil and bake for 15 minutes, then uncover and bake another 5–7 minutes until golden and toasty.
- Make the au jus
- While sliders are baking, prepare the French dip sauce:
- In a small pot, whisk together au jus mix, beef broth, and a dash of Worcestershire. Heat until warm.
- Serve and dip
- Remove sliders from oven, let them cool slightly, then serve with the warm dipping sauce on the side.
