Known as champiñones al ajillo in Spain, these super garlicky mushrooms are incredibly simple to make and one of the easiest (vegan!) Spanish tapas to enjoy at home.
Add 2 tbsp of olive oil to a large skillet. Set over medium-high heat and, once shimmering, add the mushrooms along with a generous pinch of salt. Cook, stirring frequently, until the mushrooms begin to take on colour and turn lightly brown - 8-10 minutes. Remove the mushrooms from the pan and set aside.
Add the garlic and chili flakes to the pan. Cook, stirring constantly, until very fragrant and softened - 2-3 minutes.
Return the mushrooms to the pan and pour over the wine. Cook until reduced and the strong alcoholic smell has dissipated - 2-3 minutes. Stir in the vinegar and parsley. Taste to adjust for seasoning, adding more salt if necessary. Serve immediately.
