👩🍳 Instructions
1. Prepare the Onions
Preheat the oven to 350°F (175°C).
Heat the olive oil and 2 tablespoons butter in a skillet over medium heat.
Add the sliced onions and cook for 8–12 minutes, stirring occasionally, until soft and deeply golden.
Season with a little salt and pepper.
Stir in 1 teaspoon Worcestershire sauce and cook for another minute. Remove from the heat.
2. Prepare the Slider Rolls
Without separating the individual rolls, carefully slice the entire package of rolls horizontally.
Place the bottom half into a lightly greased 9×13-inch baking dish.
3. Layer the Roast Beef and Cheese
Arrange the roast beef evenly over the bottom buns.
Top with the caramelized onions.
Place the provolone and Swiss cheese evenly over the beef and onions.
Place the top half of the rolls over the cheese.
4. Make the Buttery Topping
In a small bowl, combine:
- Melted butter
- Worcestershire sauce
- Garlic powder
- Dried parsley
- Onion powder
- Salt
Mix well.
Brush the buttery mixture generously over the tops of the slider buns.
5. Bake Until Golden and Gooey
Cover the baking dish loosely with aluminum foil.
Bake for 15 minutes.
Remove the foil and continue baking for another 8–10 minutes, or until the cheese is completely melted and the tops are golden brown.
For extra crispy tops, broil for 1–2 minutes, watching carefully so they don’t burn.
6. Make the Au Jus
While the sliders bake, combine the beef broth, Worcestershire sauce, soy sauce, garlic powder, onion powder, thyme, butter, and black pepper in a small saucepan.
Bring to a gentle simmer over medium heat.
Cook for 5–7 minutes, stirring occasionally.
Taste and adjust the seasoning if needed.
7. Slice and Serve
Let the sliders rest for about 5 minutes.
Cut into individual sandwiches and serve warm with small bowls of the homemade au jus for dipping.
That first bite—with the melted cheese, savory roast beef, caramelized onions, and warm au jus—is seriously hard to resist.
🧀 Best Cheese Choices
Provolone is the classic choice for French dip-style sandwiches, but you can easily customize these sliders.
Try:
- Provolone
- Swiss
- Mozzarella
- White cheddar
- Havarti
- Monterey Jack
For the best flavor, use a combination of two cheeses.
⭐ Tips for the Best French Dip Sliders
Don’t separate the rolls before slicing. Keeping them connected makes assembly much easier and helps the sliders bake evenly.
Use thinly sliced roast beef. Thin slices warm quickly and give you that classic French dip texture.
Caramelize the onions properly. Give them enough time to become soft and golden for maximum flavor.
Don’t skip the buttery topping. It gives the rolls a delicious golden crust and adds extra savory flavor.
Watch the broiler. The tops can go from golden to burnt very quickly.
Serve immediately. These sliders are at their absolute best while the cheese is hot and stretchy.
