Our favourite veggie burger recipe yet!
Preheat oven to 350F. Lightly whisk flax and water together to make a flax egg.
Wipe off any debris from mushrooms and then discard stems and gills. Chop into 1/2″ cubes.
Pan fry the mushrooms until cooked through and keep half the amount aside for garnish.
Transfer the other half to a food processor and add the remaining ingredients, starting with the smallest amount of bread crumbs. Pulse until chopped and mixture comes together. Add more bread crumbs as necessary.
Form into 2 large patties and place on a baking sheet fitted with parchment. Bake until nicely browned and fragrant 18-20 minutes flipping halfway.
While the patties are baking, caramelize the onions in oil with the salt and sugar in a large stirring often until soft and light golden brown.
