From the Dietitian’s Kitchen: Portobello Veggie Burger

This burger is nutrient-dense and super versatile. It can be eaten traditionally on a bun with cheese, topped with guacamole and salsa, or on a bed of lettuce. It is so delicious, that it can be eaten all by itself! No matter which way you try it, this Portobello Black Bean Burger will not disappoint.  


  • 2 cups Portobello mushrooms, cubed, gills removed
  • 2 cups cooked black beans, rinsed and divided
  • 1 cup fresh broccoli, minced
  • ½ cup red onion, minced
  • 3 XL eggs, beaten
  • ½ cup plus 2 tbsp. Panko
  • 1 tbsp. Montreal Steak Seasoning
  • 1 tbsp. Worcestershire 
  • 2 tbsp. garlic, minced
  • ¾ cup Parmesan cheese, grated
  • Olive oil


  • In large bowl, pour 1 cup of black beans and mash with a masher or fork (chunks are okay).
  • Mix in mushrooms, remaining cup of beans, broccoli, garlic, onion, Worcestershire and steak seasoning. 
  • Add in eggs, cheese and Panko. Mix gently with a large spoon until mixture is combined.
  • Take a 1-cup measuring scoop and pack with burger mix.
  • Turn measuring cup upside down and tap mixture on to plate. Repeat four more times. Mix should make approximately 5 (1 cup) patties. 
  • Set patties aside while you place a medium non-stick pan over medium heat and add in 1 tbsp. of oil or spray with oil.
  • Once the oil starts to simmer (about a minute or two), place patties in pan and cook for 4-6 minutes per side or until a golden brown crust has formed on each side. 
  • Serve with hummus, guacamole, or steak sauce.

Additional Tips

  • Should make 5 large burgers. If you prefer smaller burgers, use 1/2 cup when making patties. 
  • Freeze uncooked patties individually in plastic wrap in freezer bag or plastic container.
  • When ready to cook, let burger thaw for 30 minutes in refrigerator; then cook using recipe instructions.
