How to Make French Dip Sliders
1. Prepare the Horseradish Mayo
- In a small bowl, stir together 1/4 cup mayonnaise and 1 tablespoon cream-style horseradish. Set aside or refrigerate until ready to use.
2. Build the Sliders
- Preheat your oven to 350°F (175°C).
- Without separating the rolls, slice the entire sheet of King’s Hawaiian rolls in half horizontally. Place the bottom half in a lightly greased or parchment-lined baking dish.
- Spread the horseradish mayo evenly over the bottom layer of the rolls.
- Layer on the roast beef, followed by the caramelized onions, and finally the cheese slices. Top with the upper half of the rolls.
3. Brush with Butter Mixture
- In a small bowl, mix together 4 tablespoons melted butter, 1 teaspoon Worcestershire sauce, 1/2 teaspoon onion powder, 1/4 teaspoon garlic powder, and 1/2 tablespoon chopped parsley.
- Brush the butter mixture generously over the tops of the rolls. Reserve any extra for serving.
4. Bake the Sliders
- Cover the dish with foil and bake for 20 minutes.
- Uncover and bake for an additional 5–10 minutes or until the tops are golden and the cheese is melted.
5. Make the Au Jus
- While the sliders bake, melt 2 tablespoons butter in a saucepan over medium heat. Add 1 minced garlic clove and cook for 30 seconds until fragrant.
- Optional: Stir in 1.5 tablespoons flour to make a light roux, cooking for 1–2 minutes.
- Whisk in 2 cups beef broth, 1 tablespoon Worcestershire sauce, 1–2 teaspoons Better Than Bouillon beef base (if using), and 1 teaspoon fresh thyme.
- Bring to a simmer and cook for 5–7 minutes until slightly reduced. Season with salt and pepper to taste.
Tips & Tricks for the Best Sliders
- Use fresh rolls to prevent soggy bottoms—slightly toasting the base layer helps too.
- Make ahead: Assemble the sliders and store covered in the fridge for up to a day before baking.
- Double the jus if you love extra dipping sauce or are serving a crowd.
- Caramelize onions in advance – they freeze well and save time during prep.
- Cut with a sharp serrated knife for clean slices after baking.
Recipe Variations & Substitutions
- Dairy-free: Use vegan mayo and dairy-free cheese slices.
- Cheese swap: Try mozzarella, gruyère, or cheddar for a different flavor.
- No horseradish? Use Dijon mustard or a garlic aioli for a similar kick.
- Meat variation: Thinly sliced leftover prime rib or brisket work beautifully.
- Spicy version: Add pickled jalapeños or a dash of hot sauce to the mayo.
Serving Suggestions
- Serve with fries, sweet potato wedges, or a crisp green salad.
- Pair with cold beer, a bold red wine, or sparkling water with lemon.
- Great as a main dish or sliced in half for a fun party appetizer.
Storage, Freezing & Reheating Instructions
- Storage: Keep leftovers in an airtight container in the fridge for up to 3 days.
- Freezing: Wrap baked sliders tightly in foil and freeze up to 1 month. Thaw in the fridge overnight before reheating.
- Reheating: Warm in the oven at 325°F until heated through. Cover with foil to prevent drying.
