Ingredients
 

Instructions

  • Make the marinade. In the bottom of a medium bowl, combine olive oil, red wine vinegar, dried oregano, dijon mustard, kosher salt, freshly ground black pepper, and a pinch of sugar. Whisk until smooth. 
  • Marinate. Toss the mushrooms with the marinade until each piece is no longer dry. Cover and store in the fridge for 30 minutes.
  • Caramelize. Heat a large skillet or grill pan over medium heat. Once hot, add the marinated mushrooms as well as the excess marinade from the bottom of the bowl in a single layer. Cook for 8 minutes, flip, and cook for 7 minutes until both sides are browned and caramelized.
  • Serve. Remove from the heat. Spoon some of the leftover marinade from the pan over the mushrooms and sprinkle with flaky salt. Enjoy warm or cold.

Notes

Use at least 6 oz of portobello mushrooms. You can use more, just adjust the marinade ingredients as needed.
