  • 4 large portobello mushrooms
  • ¼ cup balsamic vinegar
  • 2 tbsp. olive oil
  • ½ tbsp. dried oregano
  • 1 tsp. garlic powder
  • 1 tsp. paprika
  • 1 tsp. sriracha
  • tsp. salt or to taste


  • Gently wash the portobellos and pat them dry with paper towels. Remove the stems and carefully pierce the mushrooms all around with a fork.
  • Prepare the marinade by mixing the balsamic vinegar, olive oil, oregano, garlic powder, paprika, salt, and sriracha in a small bowl.
  • Spoon the marinade over the mushrooms until they are covered and then let them rest for 10-15 minutes so it can be absorbed.
  • Place the mushrooms, gill side up, on the grill pan. Grill for about 5 minutes.
  • Flip the mushrooms and grill for about 4-5 minutes, brushing them with marinade drippings, if desired.




These Grilled Portobello Mushrooms are best eaten the day they are made, but they can be stored in the fridge for 2-3 days. Just place them in an airtight container until you're ready to warm and serve them. To reheat, place the mushrooms either in a microwave-safe bowl to heat or back on the grill until warmed through.
