Perfect as a versatile side dish or appetizer, these mushrooms pair wonderfully with mash, polenta, toast with goat cheese, grilled meats, or as part of a grazing board.

Ingredients

Roasted Mushrooms

  • 700g (1.4 lb) small whole white mushrooms or halved larger ones
  • 3 tbsp extra virgin olive oil
  • 1 tsp cooking or kosher salt
  • 1/2 tsp black pepper
  • 5 sprigs fresh thyme (or 1/2 tsp dried thyme)
  • 2 garlic cloves, finely minced
  • 2 garlic cloves (skin on), smashed

Balsamic Marinade

  • 4 tbsp balsamic vinegar
  • 3 tbsp extra virgin olive oil

Instructions

  1. Preheat Oven: Preheat your oven to 200°C (375°F) or 180°C (fan).
  2. Season Mushrooms: Place mushrooms in a roasting pan in a single snug layer. Toss with olive oil, then add salt, pepper, thyme, minced garlic, and smashed garlic cloves. Toss again to coat evenly.
  3. Roast Mushrooms: Roast in the preheated oven for 35 minutes, stirring or tossing well halfway through at 20 minutes. Roast until mushrooms are browned and soft.
  4. Marinate: While still hot, transfer mushrooms with all their juices into a bowl. Add balsamic vinegar and olive oil marinade. Toss thoroughly to combine.
  5. Marinate Time: Let mushrooms cool and marinate uncovered at room temperature for at least 2 hours, tossing once or twice. For best flavor, cover and refrigerate overnight.
  6. Serve: Serve the mushrooms at room temperature or slightly warmed to maximize flavor. Use the flavorful marinade juices as well.
  7. Serving Suggestions: Enjoy as part of a grazing board, on polenta or mashed potatoes, on toast with goat or cream cheese, alongside fried eggs, in risotto or risoni dishes, or with grilled meats.

Notes

  • Mushrooms: White mushrooms are preferred but cremini or other roastable mushrooms will work. Choose whole mushrooms about 3.5cm (1.4″) for even cooking. Larger ones should be halved.
  • Smashed Garlic: Smash unpeeled garlic cloves with the side of a knife to release flavor but keep mostly intact for easy removal. Adds depth to marinade flavor.
  • Leftovers: Store in the fridge for 4 to 5 days. Freezing is not recommended as mushrooms may become soggy.
