Balsamic marinated mushrooms are a deliciously flavorful side dish featuring roasted mushrooms soaked in a tangy blend of balsamic vinegar, olive oil, garlic, and fresh thyme. Perfect served warm or at room temperature, these mushrooms make a versatile addition to meals such as toast with goat cheese, grilled meats, or as part of a grazing board. The marinade infuses the mushrooms with a rich, savory taste that bursts in your mouth with every bite.

Ingredients

Roasted Mushrooms:

  • 700g/1.4 lb small whole white mushrooms or halved larger ones
  • 3 tbsp extra virgin olive oil
  • 1 tsp cooking/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: Set your oven to 200°C/375°F (180°C fan) to prepare for roasting the mushrooms.
  2. Season Mushrooms: Place the mushrooms in a roasting pan, arranging them in a single layer. Toss them with olive oil first, then sprinkle with salt, pepper, thyme, and both minced and smashed garlic cloves. Toss again to evenly coat all the mushrooms.
  3. Roast Mushrooms: Roast for 35 minutes, tossing well at the 20-minute mark to ensure even cooking. The mushrooms should become browned and tender.
  4. Prepare Marinade: While the mushrooms are still hot, transfer them and all their juices to a bowl. Add balsamic vinegar and olive oil, then toss thoroughly to coat.
  5. Marinate: Let the mushrooms cool and marinate uncovered for at least 2 hours, tossing occasionally. For deeper flavor, cover and marinate in the fridge overnight.
  6. Serve: Serve the mushrooms at room temperature or slightly warmed to enjoy their full flavor. Use the flavorful juices as a tasty addition to your serving.
  7. Serving Ideas: Enjoy on toast with goat cheese, over mash or polenta, alongside steak or grilled chicken, with fried eggs, or as part of a grazing board.

Notes

  • Mushroom Choice: White mushrooms are preferred, but cremini or other roastable mushrooms work well. Mushrooms around 3.5cm (1.4″) in size are ideal; larger mushrooms should be halved for even cooking.
  • Handling Larger Mushrooms: For portobello mushrooms, roast and then fill gill side up with marinade. They absorb the marinade fully by the next day.
  • Smashed Garlic: Smash garlic cloves with skin on using the side of a knife to release flavor but keep cloves mostly intact for easy removal after roasting.
  • Storage: Keep leftovers in the fridge for 4 to 5 days. Freezing is not recommended as mushrooms tend to become soggy.
