Ingredients

  • 1 tbsp extra-virgin olive oil
  • ½ red onion
  • 110 g mushrooms
  • 3 cloves garlic
  • 1½ tsp smoked paprika
  • 1½ tsp ground cumin
  • 1 tbsp tamari (or soy sauce)
  • ½ tsp salt
  • 1 can black beans
  • 1 large slice bread (I used gluten free)

To assemble:

  • 2 buns (I used gluten-free)
  • Lettuce
  • Sliced tomato
  • Sliced red onion
  • Mayonnaise
Metric - US Customary

Instructions

  • Begin by finely dicing the red onion and mushrooms. Crush the garlic and blend the bread into crumbs in a blender.
  • Next heat a pan on a medium heat and add the olive oil, diced onion, mushrooms and garlic. Sauté for 5 minutes until soft. If any liquid from the mushrooms remains in the pan carefully drain to remove it.
  • Drain the black beans and add them to the pan along with the smoked paprika, ground cumin, tamari and salt. Turn the heat up and combine. Cook for 5 minutes.
  • Next use a hand blender or transfer ½ of the mixture to a blend and blend for a few seconds until the black beans are no longer visible. Return the mixture back to the pan and combine with the breadcrumbs.
  • Form into 2 patties and place on a lined plate and into the fridge to chill for a minimum of 1 hour. Heat a pan on a medium heat and cover the base of the pan in a neutral cooking oil.
  • Add the burger patties and cook until browned. Carefully turn them over every few minutes to stop the bottom from burning. The aim is to cook them low and slow until they’ve cooked the whole way through. This should take approximately 12 minutes.

Notes

Step-by-Step Photos: My blog post includes helpful step-by-step photos to help guide you through making this recipe.
Substitutions & Variations: I have included a list of these in the post above.
To Store: Store in an airtight container in the fridge for up to 3 days. Reheat in the microwave or on a pan.
To Freeze: Freeze in an airtight container for up to three months. Reheat in the microwave, on the stove, or in the oven.
Tip 1: If you have a grill pan, your portobello burgers will taste more like they've come off the BBQ, but a regular frying pan also works great.
Tip 2: If you love spicy dishes, you could add in freshly chopped chilli or even chilli flakes to taste.
Tip 3: Gluten-Free bread can be pretty small. If you are having trouble keeping your patties firm, add some more bread crumbs in.
