Balsamic Marinated Mushrooms Recipe

4.8 from 105 reviews

These balsamic marinated mushrooms are tender, flavorful, and perfect for adding to grazing boards, salads, or as a savory side dish. Roasted to perfection with garlic and thyme, then marinated in a simple balsamic vinegar and olive oil dressing, they deliver a rich depth of flavor and a touch of acidity that enhances their earthiness. Serve them at room temperature or slightly warmed for the best taste experience.

Ingredients

Scale

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) or 180°C (fan) to prepare for roasting the mushrooms.
  2. Season mushrooms: Place the mushrooms in a roasting pan in a single layer. Toss them with 3 tablespoons of olive oil, then sprinkle with salt, pepper, thyme, and both the minced and smashed garlic cloves. Toss again until well combined.
  3. Roast mushrooms: Roast in the preheated oven for 35 minutes, tossing the mushrooms well at the 20-minute mark to ensure even browning. They should become browned and soft by the end of roasting.
  4. Prepare marinade: While mushrooms are hot, transfer them along with their juices into a bowl. Add 4 tablespoons balsamic vinegar and 3 tablespoons extra virgin olive oil. Toss gently to coat thoroughly.
  5. Marinate: Let the mushrooms cool and marinate uncovered for at least 2 hours, tossing once or twice. For best flavor, cover and refrigerate to marinate overnight (up to 24 hours).
  6. Serve: Serve the mushrooms at room temperature or slightly warmed to enjoy the fullest flavor. Use the flavorful marinade juices as a dressing or drizzle.
  7. Serving suggestions: These mushrooms are versatile—add them to grazing boards, serve on polenta or mashed potatoes, top toast with goat or cream cheese, accompany fried eggs, or mix into risotto or risoni/orzo for a delicious meal.

Notes

  • Mushrooms shrink about 25-30% during roasting, so use a roasting pan rather than a tray for easier tossing.
  • Use both minced and smashed garlic for a deeper garlic flavor—smashed cloves impart aroma during roasting but are typically removed or eaten whole.
  • Marinating time affects flavor intensity; the longer you marinate (up to 24 hours), the more intense the balsamic infusion.
  • Serve at room temperature or slightly warmed to highlight the best flavors of the marinade and mushrooms.
