Portobello Mushrooms Recipe
Introduction
Baked portobello mushrooms make a delicious and hearty vegetarian main or side dish. Their meaty texture soaks up a flavorful marinade, resulting in a savory and satisfying meal that’s easy to prepare.

Ingredients
- 2 large portobello mushrooms
- 2 tablespoons soy sauce (can substitute with 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
- Step 1: Preheat your oven to 400°F (205°C).
- Step 2: In a baking dish that fits both mushrooms, combine the soy sauce, balsamic vinegar, garlic, ginger, and olive oil to create the marinade. You can line the dish with foil for easier cleanup if you like.
- Step 3: Place the mushrooms in the dish, stem side down, and rub the marinade all over them. Let them sit for 15 minutes to absorb the flavors.
- Step 4: After 15 minutes, rub the mushrooms again with the marinade to refresh the coating, then place the dish in the oven.
- Step 5: Bake the mushrooms for 15 minutes. Remove the dish, flip the mushrooms over, and spoon any remaining marinade over the tops.
- Step 6: Continue baking for another 5 to 15 minutes, depending on the size of the mushrooms, until tender and juicy.
- Step 7: Remove the mushrooms from the oven and let them rest for 5 minutes before slicing and serving.
Tips & Variations
- Try adding fresh herbs like thyme or rosemary to the marinade for an aromatic twist.
- Use a grill pan instead of the oven for a smoky flavor and grill marks.
- For a richer taste, brush the mushrooms with melted butter instead of olive oil.
Storage
Store any leftover baked portobello mushrooms in an airtight container in the refrigerator for up to 3 days. To reheat, warm them gently in a skillet or oven until heated through to preserve their texture.
