How to Make French Dip Sliders Recipe
Step 1: Prepare the Oven and Baking Sheet
Start by preheating your oven to 350 degrees F and line a baking sheet with parchment paper. This step is simple but important to ensure your sliders bake evenly without sticking, making cleanup a breeze.
Step 2: Caramelize the Onions
Melt 4 tablespoons of butter in a large skillet over medium heat. Add the thinly sliced onions and cook them slowly, stirring often, until they become soft and caramelized, about 15 minutes. Once done, season with minced thyme, salt, and pepper to infuse extra layers of flavor. This step brings out a sweet earthiness that perfectly balances the savory beef.
Step 3: Slice and Arrange the Buns
Using a bread knife, carefully slice the Hawaiian dinner rolls in half horizontally, creating a top and bottom for each slider. Place all the bottom halves evenly spaced on the lined baking sheet. This creates a stable base for layering your delicious fillings.
Step 4: Layer the Sliders
On each bottom bun, add a generous layer of deli sliced roast beef, followed by a slice of Swiss cheese. Top with the caramelized onions for that sweet and savory touch. Finally, place the top bun halves back in place. The layering creates a mesmerizing blend of flavors and textures in every bite.
Step 5: Make the Butter-Mustard Glaze
In a small bowl, combine 3 tablespoons of butter with 2 tablespoons of Dijon mustard. Microwave for about 10 seconds until melted, then stir to combine into a smooth glaze. This glaze will give the buns a beautiful golden shine and an extra hit of flavor.
Step 6: Glaze and Season the Tops
Brush the butter-mustard mixture evenly over the top buns. Then sprinkle 1 ½ tablespoons of dried onion soup mix over the glaze. This adds a delightful crunch and boosts the savory onion flavor, tying the whole flavor profile together.
Step 7: Bake to Perfection
Cover the sliders loosely with foil and bake for 15 to 20 minutes until the Swiss cheese is melted to gooey perfection. Remove the foil and bake for an additional 5 minutes if you want to toast the buns slightly for an extra layer of texture. Then, they’re ready to be served!

Reheating

FAQs
Can I use a different type of cheese?
Absolutely! While Swiss cheese melts beautifully and complements the flavors well, provolone or mozzarella are great alternatives if you prefer a milder or creamier taste.
Is it necessary to use Hawaiian rolls?
Hawaiian rolls add a subtle sweetness and softness that pairs wonderfully with the savory beef and onions. However, you can substitute with any soft dinner roll or slider bun you like.
Can I make these sliders vegetarian?
You can! Replace the roast beef with sautéed mushrooms or a savory plant-based meat alternative, and use vegetable broth for the au jus to keep the same rich flavors without meat.
How do I make the au jus gravy mix?
Most au jus gravy mixes require whisking the mix into boiling water until fully dissolved. Be sure to prepare it just before serving for the best flavor and temperature.
Can these sliders be made gluten-free?
Yes! Simply swap out the Hawaiian rolls for gluten-free slider buns and ensure your au jus mix does not contain gluten. This way, everyone can enjoy these tasty sliders worry-free.
