Greek-Style Mushrooms

These Greek-style marinated mushrooms are a classic meze appetizer: whole button mushrooms soaked in a lemony, garlicky olive oil brine infused with fennel seeds, oregano, celery seed, and bay leaf. The microwave speeds up the marinade-making process, but the real magic happens during the 24-hour chill.

The marinade gets cooked first without the mushrooms. This blooms the spices and lets the flavors concentrate before the mushrooms ever touch the liquid. When the mushrooms go in, they cook on medium power for just three minutes, enough to soften them slightly so they absorb the marinade without turning rubbery.

That full day in the fridge isn’t negotiable. The mushrooms need time to drink up the olive oil, lemon, and vinegar. After 24 hours, each one is saturated with tangy, herbal flavor all the way through. Serve them cold on a bed of parsley or endive with a slotted spoon.

Kitchen Tips

• Don’t trim the mushroom stems beyond the soiled end. Whole mushrooms with stems look better on the plate and hold more marinade.
• Stir every 60 seconds during the medium-power cook. Mushrooms release liquid unevenly and some can overcook while others barely warm through.
• The olive oil solidifies slightly when chilled. Let the mushrooms sit at room temperature for 10 minutes before serving so the oil liquefies again.

Variations

• Add sliced sun-dried tomatoes and Kalamata olives to the marinade for a more robust appetizer platter.
• Use cremini mushrooms instead of button for a deeper, earthier flavor.
• Toss the marinated mushrooms into a salad or onto a pizza as a topping.
