The mellow taste of dried porcini mushrooms makes a noticeable difference in this (not your regular) burger. What's better is that you can whip these up in no time for a quick lunch fix or light dinner.
In a frying pan heat oil and and onions and thyme. Cook gently until slightly caramelised. Allow to cool.
Combine beef mince, mushroom powder, parmesan, breadcrumbs and egg.
Add cooked onions mixture and salt
Mix thoroughly (with hands is best) and form into 6 patties.
Fry or grill patties as you like and serve in a burger bun with egg, cheese, greens and sauce.
Build your burger with your favourite fillings but I think the simple patty on some cheese with some baby spinach in a crusty bun highlights the beefy mushroom flavour.
