Method
Preparation
- In a large skillet over medium heat, melt the butter. Add the onions and coat them in the butter. Cook for about 12-15 minutes, stirring occasionally, until soft and browned but not burnt.
- Add the thyme, salt, and pepper. Stir to combine, then take off the heat and set aside.
- Preheat the oven to 350 degrees F. Take the rolls out of the package, leaving them intact. Slice the rolls across to separate the tops and bottoms. Place the bottoms, cut side up, into an 11 by 7 baking dish.
- Top with half of the cheese. Add the roast beef, then spread the onions on top. Add the remaining cheese, and place the tops of the rolls on top.
- In a small bowl, mix the melted butter and onion soup mix. Brush or pour this mixture on top of the rolls.
- Cover loosely with foil, making sure the foil is not touching the tops of the rolls, and bake for 25 minutes. Remove the foil and bake for an additional 5 minutes to brown the rolls.
- While the rolls are baking, prepare the au jus according to the package directions with the water.
- Serve the rolls warm, directly from the oven with optional garnish of parsley and au jus on the side for dipping.
Notes
For extra flavor, consider adding additional spices like garlic powder or paprika to the butter mixture. Feel free to use your favorite type of cheese, like Swiss or cheddar, if you prefer. If you want more crunch, add some sliced jalapeƱos or pickles. Shredded beef can be used instead of deli roast beef for a different texture. Store the sliders in an airtight container in the refrigerator for up to 3 days.
