Ingredients

For the French Onions:

  • 2 tablespoons unsalted butter
  • 6 cups chopped onion
  • 1/2 cup beef broth
  • 1 tablespoon Worcestershire sauce

For the Sliders:

  • 24 slider rolls, cut in half horizontally
  • 16 slices McKenzie Natural Artisan Deli Swiss Cheese, divided
  • 16 slices McKenzie Natural Artisan Deli Roast Beef

For the Butter Topping:

  • 1/2 cup unsalted butter, melted
  • 2 teaspoons Dijon mustard
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon salt

Instructions

For the French Onions:

  1. Caramelize Onions: In a large skillet, melt butter over medium heat. Add chopped onions and cook, stirring occasionally, until onions are caramelized and golden brown, about 20-25 minutes.
  2. Deglaze Pan: Pour in beef broth and Worcestershire sauce, scraping up any browned bits from the bottom of the skillet. Simmer for an additional 5 minutes, then remove from heat.

For the Sliders:

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper for easy cleanup.
  2. Assemble Sliders: Place the bottom halves of the slider rolls in the prepared baking dish. Layer half of the Swiss cheese slices over the rolls, followed by the roast beef slices and caramelized onions. Top with the remaining Swiss cheese slices and the other halves of the slider rolls.
  3. Prepare Butter Topping: In a small bowl, whisk together melted butter, Dijon mustard, Worcestershire sauce, garlic powder, and salt.
  4. Drizzle Butter Topping: Evenly drizzle the butter topping over the assembled sliders, ensuring they are fully coated.
  5. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 15-20 minutes, or until the cheese is melted and the sliders are heated through.
  6. Serve: Remove from the oven and let the sliders cool slightly before serving. Use a sharp knife to cut the sliders along the pre-scored lines. Serve warm and enjoy!

Cook Notes and Variations

  • Make-Ahead Option: You can prepare the caramelized onions and assemble the sliders ahead of time, then cover and refrigerate until ready to bake. Simply drizzle with the butter topping and bake as directed when ready to serve.
  • Add-Ons: Customize your sliders by adding extra ingredients such as crispy bacon, sliced mushrooms, or roasted bell peppers for added flavor and texture.
  • Cheese Swap: Feel free to substitute the Swiss cheese with your favorite cheese variety, such as cheddar, provolone, or Gruyère, for a different flavor profile.

Keto and Low-Carb Versions

For those following a keto or low-carb lifestyle, here’s how you can make a keto-friendly version of French Onion Roast Beef Sliders:

  • Bread Substitute: Use low-carb or keto-friendly bread or rolls as a substitute for the slider rolls. Look for options made with almond flour, coconut flour, or psyllium husk.
  • Onion Reduction: Reduce the amount of caramelized onions used in the recipe to lower the carb content. You can also caramelize onions with low-carb sweeteners like erythritol or monk fruit sweetener for a keto-friendly alternative.
  • Butter Topping: Use ghee or coconut oil instead of butter in the topping mixture to keep it keto-friendly.

Frequently Asked Questions (FAQs)

Q: Can I use store-bought caramelized onions instead of making them from scratch? A: Yes, you can save time by using store-bought caramelized onions. Look for them in the condiments or deli section of your grocery store. Simply warm them up before adding them to the sliders.

Q: Can I freeze leftover sliders for later? A: Yes, you can freeze leftover sliders for up to 1 month. Wrap them individually in aluminum foil or plastic wrap, then place them in a freezer-safe bag or container. To reheat, thaw in the refrigerator overnight and bake in the oven until heated through.

Q: Can I make these sliders vegetarian? A: Absolutely! You can make vegetarian sliders by substituting the roast beef with sliced grilled portobello mushrooms or vegetarian deli slices. Add extra cheese and vegetables for a hearty vegetarian option.
