Just Mushrooms and Marinade

Portobellos: Look for mushrooms with firm, dry caps. They should be large and plump with a dark brown color. Be sure to brush off the dirt with a paper towel instead of rinsing them. Remove the gills with a spoon, if desired.

Marinade: Oil and acid are the basics for any great marinade. Sesame oil and garlic with ginger create a fantastic umami flavor profile. Chili flakes add a touch of heat.


  • Try marinating sliced baby bellas (also known as creminis), and cooking them in an outdoor grill pan for a burger topping or tasty side dish. Creminis are younger portobellos, with a similar flavor and texture, and can be used in many of the same dishes as portobellos.
  • Put a tasty spin on grilled portobello mushrooms. After grilling, drizzle the mushrooms with a balsamic vinegar reduction for a sweet and tangy flavor.
  • You can also brush the grilled mushroom with melted butter and grate some black pepper on top. Sprinkle some fresh herbs like thyme or rosemary before serving to add an extra layer of flavor.

Grilled Portobello Mushrooms

This easy recipe for grilled portobello mushrooms creates a savory and delicious low carb dish.
Prep Time 10 minutes
Cook Time 9 minutes
Marinating Time 15 minutes
Total Time 34 minutes
Servings 4 servings



  • 4 large portobello mushrooms or 8 small portobello mushrooms
  • 2 tablespoons olive oil
  • 2 tablespoons soy sauce
  • 1 teaspoon sesame oil
  • 1 clove garlic minced
  • 1 teaspoon minced fresh ginger
  • ¼ teaspoon chili flakes
  • salt to taste


  • Wipe the mushrooms clean with a damp paper towel and remove the stems. Using a sharp knife, cut a few shallow cuts across the surface of the tops of the mushrooms (just enough to allow the marinade to get into the mushroom).
  • In a glass bowl or freezer bag, mix olive oil, soy sauce, sesame oil, garlic, ginger, and chili flakes. Toss the mushrooms to coat and marinate for 15 to 60 minutes.
  • Preheat the grill to medium-high heat.
  • Place the mushrooms, stem side down on the grill and cook for 5 to 6 minutes. Flip the mushrooms over and cook for an additional 4 to 5 minutes or until tender.


  • A longer marinating time will result in deeper flavors.
  • Leftovers will keep in an airtight container in the refrigerator for up to 4 days.
