Instructions
1
In a wide, heavy skillet, heat the olive oil over medium-high heat. Add the thinly sliced onions along with 1/8 teaspoon of coarse salt and a few grinds of fresh black pepper. Cook the onions, stirring often, until they become caramelized and sticky, about 15 minutes. Once browned, remove the skillet from the heat and set aside.
2
In a second large skillet, melt the unsalted butter over medium-high heat. Add all the sliced shiitake and white mushrooms, chopped garlic, another 1/8 teaspoon of coarse salt, and a few grinds of black pepper. Cook the mushroom mixture, stirring frequently, until the mushrooms are nice and browned, approximately 15 minutes.
3
Raise the heat to high, pour in the cognac, and cook for an additional minute until the liquid evaporates completely. Remove this pan from the heat and combine the mushroom mixture with the caramelized onions.
4
Preheat your broiler and split the potato slider buns in half, placing them cut side up on a broiler rack. Generously cover both halves of the buns with slices of sharp cheddar cheese. Broil for 1 to 2 minutes, or until the cheese is melted and bubbly. Afterward, carefully remove the buns from the broiler.
5
To assemble the sliders, pile a generous amount of the mushroom and onion mixture on each bottom bun. Place the top bun over the filling. Serve immediately and enjoy your culinary creation!
