Ingredients List
To create these delicious French Onion Roast Beef Sliders, you will need the following ingredients:
- 1 pound of roast beef, thinly sliced
- 1 large onion, thinly sliced
- 2 tablespoons of unsalted butter
- 1 cup of beef broth
- 8 ounces of provolone cheese, shredded (substitute with mozzarella for a milder flavor)
- 12 slider buns (use whole grain for a healthier option)
- 1 tablespoon of Worcestershire sauce
- Salt and pepper to taste
- Optional: fresh thyme leaves for garnish

Timing
Preparation time for these sliders is just 15 minutes, and you’ll be cooking them for approximately 30 minutes, leading to a total time of 45 minutes. This is about 40% less than the average slider recipe, making it a quick yet satisfying dish to whip up for any occasion!
Step-by-Step Instructions
Step 1: Caramelize the Onions
In a large skillet over medium heat, melt 2 tablespoons of unsalted butter. Add the sliced onions and season with a pinch of salt. Cook for about 15 minutes, stirring occasionally, until the onions are golden brown and caramelized. If desired, add a splash of beef broth for enhanced flavor.
Step 2: Warm the Roast Beef
Once the onions are perfectly caramelized, add the thinly sliced roast beef along with 1 cup of beef broth and 1 tablespoon of Worcestershire sauce. Stir until the beef is warmed through, about 5-7 minutes. Taste and adjust seasoning with salt and pepper if necessary.

Step 3: Assemble the Sliders
Preheat your oven to 350°F (175°C). Slice the slider buns in half and place the bottom half in a baking dish. Layer the warm roast beef and onion mixture evenly over the buns, followed by a generous amount of shredded provolone cheese. Cap with the top halves of the buns.
Step 4: Bake the Sliders
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 15 minutes, then remove the foil and bake for an additional 10 minutes or until the cheese is bubbly and the buns are slightly toasted.
Step 5: Serve with Style
Remove the sliders from the oven and let them cool for a few minutes. Slice into individual servings and sprinkle fresh thyme leaves on top, if using. Serve warm, and watch them disappear!
