French Onion Beef Sliders

Get ready for the ultimate party-worthy sliders that combine two comfort food favorites – juicy beef burgers and rich French onion soup. These handheld delights are about to become your new secret weapon for feeding a crowd with maximum flavor and minimum fuss.

Picture this: tender caramelized onions, perfectly seasoned beef, and melty cheese, all tucked into soft dinner rolls and topped with an everything bagel glaze that takes these sliders from great to absolutely irresistible. The best part? They come together in under an hour.

Ingredients

For the filling:

• ¼ cup butter
• 2 medium yellow onions, sliced thinly
• ½ teaspoon salt
• 1.5 lb ground beef
• 2 Tablespoons all-purpose flour
• ¼ cup worcestershire sauce
• 1 teaspoon beef bouillon
• 1 Tablespoon minced garlic
• ¼ teaspoon ground pepper
• 12 dinner rolls
• 12 slices gruyere, gouda or havarti cheese

For the glaze:

• 3 Tablespoons butter, melted
• 1 Tablespoon worcestershire sauce
• 1 Tablespoon Everything Bagel Seasoning

Steps

1. In a large cast iron skillet over low/medium heat, melt ¼ cup butter. Add sliced onions and sprinkle with salt. Cook for 15-18 minutes until deep golden brown, stirring every 2-3 minutes. The onions should be soft and caramelized, not crispy or burnt.

• Watch carefully during the final 5 minutes – stir every 1-2 minutes as onions can quickly go from perfect to burnt
• If onions are browning too quickly, reduce heat to low

1. Add ground beef to the caramelized onions. Cook for 5-7 minutes until beef is no longer pink, breaking into small pieces with a wooden spoon. Drain excess grease into a heat-safe container, never down the drain.
2. Sprinkle 2 Tablespoons flour over the meat mixture and stir well. Add worcestershire sauce, beef bouillon, garlic, and pepper. Simmer for 2-3 minutes until sauce thickens to a gravy-like consistency.
3. Preheat oven to 350°F (175°C). Slice rolls horizontally, keeping them connected. Place bottom half in a 9×13 inch baking pan.
4. Layer the filling evenly over roll bottoms, top with cheese slices to completely cover, then add roll tops.
5. For the glaze: Combine melted butter, worcestershire sauce, and everything bagel seasoning. Brush generously over roll tops.
6. Cover pan with foil and bake for 10-15 minutes until cheese is completely melted and sliders are heated through. Edges should be lightly crispy and tops golden brown.
