How to Make French Dip Sliders
Step-by-Step Instructions
Follow these steps for perfect, mouthwatering French dip sliders:
-
- Melt the butter in a large skillet over medium heat. Add the sliced onions and cook for about 12-15 minutes, stirring occasionally, until the onions are soft and browned.
- Stir in thyme, salt, and pepper, then remove from heat and set aside.
- Preheat the oven to 350°F. Keep the rolls intact and slice them horizontally to separate the tops from the bottoms. Place the bottom halves, cut side up, in an 11×7 baking dish.
- Layer half of the provolone cheese on the bottom halves, followed by the roast beef and the cooked onions. Top with the remaining cheese and place the tops of the rolls on.
- In a small bowl, mix the melted butter with the onion soup mix and brush it over the tops of the rolls. Alternatively, pour the mixture over the rolls.
- Loosely cover the dish with foil, ensuring it does not touch the rolls, and bake for 25 minutes. Remove the foil and bake for an additional 5 minutes to brown the tops.
- While the sliders are baking, prepare the au jus according to package instructions using water. Serve the sliders with optional parsley garnish and au jus for dipping.
