A fun twist on a classic sandwich‚ these French Dip Sliders are a deliciously easy appetizer or dinner idea for any day of the week! FRENCH DIPS MADE INTO SLIDERS I have always been a fan of French Dips. They are really one of my favorite sandwiches. When it comes to these French Dip Sliders‚ it takes that favorite sandwich to a whole other level. I love when I can have things in smaller portions that I can use as an appetizer or meal and not have to commit to one larger sandwich. With all the same great flavors of the classic‚ these are baked up with cheese‚ onions‚ roast beef and then a butter onion soup topping. Add in the au jus dipping sauce and this French Dip Slider recipe is a real winner! FREQUENTLY ASKED QUESTIONS: What rolls are best for French Dip Sliders? We usually use Hawaiian Sweet Rolls but you can use any of your favorite slider buns for this recipe. We like the contrast of the sweet rolls with the sandwich itself. Do I have to use provolone cheese? While this is the most common cheese used for French Dips you can use others such as mozzarella or even Swiss cheese. Do I have to make the dipping sauce? These are great alone and don’t require the au jus. But they’re called French Dips because of the au just dipping sauce so we make the sauce. Can I use another meat besides roast beef? While we want to stick with beef‚ you can swap out the deli roast beef with leftover pot roast‚ Mississippi roast‚ or any leftover beef you have on hand will work with this recipe. Is the Onion Soup Mix on top really necessary? No. If you feel like it is onion overload‚ just don’t use it. If you want‚ you can just melt a little butter and pour that on top. I also have a recipe for Homemade Onion Soup Mix as well. How do I store leftover French Dip Sliders? These can be stored covered in an airtight container or in pan in the refrigerator where they will keep for 2-3 days. You can reheat in the oven until heated through or in the microwave. INGREDIENTS NEEDED FOR FRENCH DIP SLIDERS: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE) HOW TO MAKE FRENCH DIP SLIDERS In a large skillet over medium heat‚ melt the butter. Add the onions and coat in the butter. Cook‚ stirring occasionally‚ for about 12-15 minutes until the onions are soft and browned but not burnt. Add the thyme‚ salt‚ and pepper‚ stir to combine‚ take off the heat‚ and set aside. Preheat the oven to 350°F. Take the rolls out of the package‚ leaving the rolls intact. Take a large knife and slice the rolls across so you have the tops and bottom separated. Place the bottom‚ cut side up into an 11×7-inch baking dish. Top with half of the cheese.  Add the roast beef. Top with the onions‚ spreading them out.  Add the remaining cheese. Then add the tops of the rolls on top. In a small bowl stir together the melted butter and onion soup mix. I like to brush this mixture on top of the rolls to make sure it’s evenly distributed but you can just pour the butter sauce on top. Cover loosely with foil‚ you want to make sure the foil is not touching the tops of the rolls and bake for 25 minutes. Take the foil off and bake an additional 5 minutes to brown the rolls.  While the rolls are baking‚ prepare the au jus per the package directions with the water. Serve the rolls with an optional garnish of parsley and au jus on the side for dipping. CRAVING MORE RECIPES?
