These sliders will be a huge hit with your family and friends at your next gathering. The seasoned and buttery buns are packed with caramelized onions, melted cheese and flavourful ground beef. A friend kindly shared the recipe with me after I sampled one… and then had to have a second one! So yummy! You can load on the cheese. Not only does it help to hold the beef together in a faux patty, but it really solidifies the french onion flavor.
French Onion Beef Sliders
• 8 tablespoons butter, divided
• 2 large sweet onions, sliced
• 2 pounds ground beef
• 2 tablespoons beef bouillon, divided
• 1 tablespoon Worcestershire sauce, divided
• Kosher salt and black pepper, to taste
• 24 slider buns
• 12–16 ounces provolone, gruyere or
swiss cheese, shredded
• 2 tablespoons sesame seeds
• 1 tablespoon fresh thyme
• 1 teaspoon onion powder
• 1 teaspoon garlic powder
Melt 2 tablespoons of the butter in a skillet over medium heat. Add in the onions and reduce the heat to medium low. Cook, stirring occasionally, until lightly caramelized, about 25-30 minutes. If the onions start to look dry or burnt, add a tablespoon of water to the pan. In a large bowl, mix the ground beef with half of the beef bouillon and half of the Worcestershire sauce. Season with salt and pepper. Add the beef to the skillet full of onions. Increase heat to medium-high and brown the beef, breaking it up into large crumbles, and mixing with the onions as you go. Once browned, drain off excess grease. Preheat the oven to 350°F. Lightly grease a large baking sheet. Separate the tops from the bottoms of the slider buns. Fit the slider bottom buns tightly on the baking sheet. Evenly distribute the beef and onion mixture over the bottom buns. Top with provolone cheese. Cover with the top buns. In a microwave safe bowl, melt the butter with the remaining beef bouillon. Stir in the remaining Worcestershire sauce and continue to mix until well-combined. Using a pastry brush, brush the beefy butter mixture over the top buns. Sprinkle with the sesame seeds, thyme, onion powder, and garlic powder. Bake the sliders until the cheese is fully melted and the tops of the rolls are lightly browned, about 20 minutes.
