Ingredients

Scale

Marinade and Mushrooms

  • 2 large portabello mushrooms
  • 2 Tablespoons soy sauce (can substitute tamari or coconut aminos)
  • 1 Tablespoon balsamic vinegar
  • 1/2 teaspoon minced garlic
  • 1/4 teaspoon minced or grated ginger root
  • 1/2 Tablespoon olive oil

Instructions

  1. Preheat Oven: Preheat your oven to 400° F (205° C) to get it ready for baking the mushrooms.
  2. Make Sauce: In a baking dish that fits both mushroom caps, combine soy sauce, balsamic vinegar, minced garlic, grated ginger, and olive oil. Stir to create the marinade.
  3. Marinate Mushrooms: Place the portobello mushroom caps into the marinade, stem side down, and rub the sauce onto their surfaces. Let them sit and marinate for 15 minutes to absorb the flavors.
  4. Start Baking: After marinating, rub the mushrooms again with the sauce to enhance flavor before putting them into the oven.
  5. Bake and Flip: Bake the mushrooms for 15 minutes. Remove them from the oven, turn them over, spoon any remaining sauce over the top, then continue baking for an additional 5 to 15 minutes, depending on their size, until tender.
  6. Serve: Remove the mushrooms from the oven and let them rest for 5 minutes before slicing and serving to allow juices to redistribute.

Notes

  • For easier cleanup, line your baking dish with foil before adding the marinade.
  • Cooking time after flipping varies; larger mushrooms will need closer to 15 minutes while smaller ones may take less.
  • You can substitute soy sauce with tamari or coconut aminos for gluten-free or soy-free options.
  • Letting mushrooms rest after baking helps retain their juices and enhances texture.
