Ingredients
Method
- Roast mushrooms at 200°C / 180°C fan / Gas 6 for 20 minutes. Chop finely.
- Cook onion 5–6 minutes, add garlic 1 minute. Cool.
- Mash black beans, leaving some texture.
- Combine mushrooms, onion mixture, oats, spices, egg and breadcrumbs into beans. Season.
- Shape into 4 patties, chill 30 minutes.
- Fry 4–5 minutes per side until golden and firm.
- Serve in toasted buns with toppings.
Notes
Roasting the mushrooms first is essential to avoid a wet, crumbly patty.
Chilling before cooking helps the burgers hold their shape under heat.
Uncooked patties freeze well for up to 3 months.
Can be made vegan with a flax egg in place of the regular egg.
