8 mini sliders


  • 8 mini hamburger buns

  • 6 tablespoons olive oil, divided

  • 2 cloves garlic, minced

  • 1 (8 ounce) package sliced fresh mushrooms

  • ¼ cup water

  • ¼ cup oyster sauce

  • 2 ounces butter lettuce, shredded

  • 1 English cucumber, thinly sliced

  • 1 tomato, thinly sliced and quartered

  • 8 dill pickle slices


  1. Preheat the oven to 350 degrees F (175 degrees C). Line a baking sheet with aluminum foil.

  2. Drizzle burger buns with enough oil to flavor and moisten the buns but not make them soggy, about 4 tablespoons, and place on the prepared baking sheet.

  3. Bake buns in the preheated oven until bottoms become golden brown, about 8 minutes. Flip buns over and cook until second side is golden brown, about 5 minutes more.

  4. While buns bake, heat remaining 2 tablespoons olive oil in a small pan over medium heat. Add garlic to hot pan so it sizzles and cook for 30 seconds. Add mushrooms and water; simmer, stirring constantly, until shrunken in size, about 3 minutes. Mix in oyster sauce and cook an additional minute.

  5. Assemble slider from the bottom up. Place a bun base on a plate and add a generous amount of lettuce. Add a cucumber slice, a piece of tomato, and a slice of pickle. Add a tablespoon of cooked mushrooms and top with the top bun. Repeat for remaining sliders.
