Loaded Philly Cheesesteak Sliders with Caramelized Onions and Cheese Whiz Step-by-step instructions

Before you start

Before starting, set out the butter and Cheese Whiz so they come to room temperature. Slice the onions and shave the ribeye if not already prepared. Preheat the oven to 375°F (190°C). Have the baking dish ready and the garlic herb butter melted.

Arrange all ingredients within reach, as the cooking moves quickly once the skillet is hot. This recipe comes together in about 30 minutes, so a little mise en place ensures smooth cooking.

Instructions

Caramelize and Sear

1. 1Caramelize the onions
   Melt the butter in a large skillet over medium heat. Add the sliced onions and cook, stirring occasionally, until deeply golden and sweet, about 15 minutes. Season with a pinch of salt.
   Look for Onions are soft, golden brown, and smell sweet.
   Tip Stir less often for deeper caramelization.
2. 2Sear the ribeye
   Increase the heat to high and add the shaved ribeye to the skillet. Sear quickly, tossing constantly, until browned and just cooked through, about 2 minutes. Stir in the Worcestershire sauce and season with salt and pepper. Let it rest for 3 minutes before slicing.
   Look for Beef is browned and sizzling, no pink remaining.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Work in batches if needed to avoid steaming.

The onions turn golden and translucent, releasing a sweet, buttery aroma. The ribeye sears with a loud sizzle and browns quickly, releasing a rich, beefy smell. The Worcestershire sauce adds a tangy note as it hits the hot pan. The beef should be cooked through but still tender, with no pink remaining. The skillet should have a nice fond from the searing, which will add flavor to the filling.

Assemble and Glaze

3. 3Assemble the sliders
   Preheat the oven to 375°F (190°C). Slice the connected rolls in half horizontally. Place the bottom half in a baking dish. Layer with provolone slices, then the cooked steak and onions. Pour the warm Cheese Whiz evenly over the top.
   Look for Rolls are filled and topped with cheese sauce.
   Tip Spread the filling evenly to the edges.
4. 4Top and glaze
   Place the top half of the rolls over the filling. Brush the tops generously with the melted garlic herb butter.
   Look for Tops are evenly coated with butter.
   Tip Use a pastry brush for even coverage.

The bottom rolls are lined with provolone, then topped with the hot steak and onions. The Cheese Whiz pours over in a smooth, golden stream, coating the filling.

The top rolls are placed and brushed with garlic herb butter, which glistens under the light. The assembled sliders look inviting, with layers of cheese and meat visible at the edges. The butter glaze is evenly spread, promising a golden crust.

Bake and Serve

5. 5Bake until golden
   Bake the sliders for 12 minutes, until the tops are golden brown and the cheese is bubbling around the edges. Remove from the oven and let cool for 2 minutes before pulling apart.
   Look for Tops are golden, cheese is bubbly and hot.
   Tip Let rest briefly so the filling sets slightly.

The sliders emerge from the oven with deep golden tops and bubbling cheese around the edges. The garlic butter has created a crisp, fragrant crust. When pulled apart, long strings of provolone stretch, and the Cheese Whiz oozes out. The aroma is a mix of toasted bread, caramelized onions, and savory beef. The sliders are hot and steamy, ready to be served immediately.

Common mistakes

Avoid overcooking the ribeye, as it can become tough and chewy. Sear it quickly over high heat and remove it from the pan as soon as it is browned. Do not crowd the skillet; cook in batches if necessary.

Overcaramelizing the onions can make them bitter, so watch them closely and stir occasionally. When assembling, do not overfill the rolls, as the filling may spill out during baking. Finally, do not skip the garlic butter glaze—it adds essential flavor and helps the tops brown beautifully.

How to tell it’s done

The sliders are done when the tops are golden brown and the cheese is bubbling around the edges. The internal temperature of the beef should have reached at least 145°F (63°C) during searing.

To check, insert an instant-read thermometer into the center of a slider; it should read hot throughout. The rolls should feel firm but spring back when pressed. Let the sliders rest for 2 minutes before pulling apart to allow the cheese to set slightly, making them easier to handle.
