Portobello Mushroom Burgers

It’s June, and while PCF’s Home Run Challenge has just wrapped, the baseball season is going strong. Need a healthy meal while you watch the games this summer? Look no further! This month’s recipe is Portobello Mushroom Burgers. These are a hit for meat- and veggie-lovers alike. So, whether you’re at the stadium (and looking forward to dinner afterwards) or enjoying the game from home, join us in cooking this delicious and healthy meal!

To make your burgers shine, you’ll need to add all of the burger fixings. Tomato, lettuce, onion, and pickles are a must in our book. And, as our Foodie Friday regulars likely know, research suggests that some nutrition recommendations may reduce the risk of developing lethal prostate cancer and cardiovascular disease. A recent study provides more evidence that for patients diagnosed with localized prostate cancer, choosing plant-based foods rather than animal products may be associated with a lower risk of the cancer getting worse or coming back. (Learn more in this video.) Vegetarians and vegans are also at lower risk of other conditions that can co-occur in patients with prostate cancer: heart disease, type 2 diabetes, high blood pressure, and obesity.

Portobello Mushroom Burgers

Prep time: 25-35 minutes

Cook Time: 10-15 minutes (grilled); 20-25 minutes (roasted)

Serves: 4


  • 4 large portobello mushrooms
  • 1 tbsp. olive oil
  • 2 tbsp. balsamic vinegar
  • 1 tbsp. tamari or low-sodium soy sauce
  • 1 pinch sea salt
  • 1 pinch black pepper
  • 4 whole wheat hamburger buns (Pro Tip: substitute your bun with a lettuce wrap to ditch the bread!)
  • Lettuce
  • Sliced tomato
  • Sliced onion
  • Pickles
  • Ketchup and mustard, if desired


  1. Remove the stems and clean the caps of the mushrooms. Place mushrooms on a large, flat pan or plate.
  2. In a small bowl, whisk olive oil, balsamic vinegar, tamari, sea salt, and pepper. Pour over mushrooms and marinate for 20-30 minutes. 
  3. If you have a grill or grill pan, grill the mushrooms for 5 to 7 minutes per side or until tender. If you do not have a grill, preheat the oven to 375 degrees Fahrenheit. Roast mushrooms on a parchment paper-lined baking sheet for 20-25 minutes or until tender and slightly caramelized.
  4. Serve the mushrooms on buns (or wrap in lettuce) with sliced tomato, sliced onion, pickles, lettuce, and any additional desired toppings.
