Ingredients
Method
- Mix flax egg and let sit 5 minutes. Pat beans very dry, then mash in a large bowl until two-thirds broken down with some whole beans remaining.
- Sauté onion in 1 tbsp oil over medium heat for 4-5 minutes until soft. Add garlic and cook 30 seconds. Cool slightly.
- Combine beans, onion mixture, breadcrumbs, spices, and flax egg. Mix well, shape into 4 patties, and chill 15 minutes.
- Heat remaining 1 tbsp oil in a skillet over medium heat. Cook patties 4-5 minutes per side until deeply browned. Serve on toasted buns.
Notes
Chill time is not included in the prep time but is important for structure. The patties can be shaped and refrigerated up to a day ahead, just cook them straight from the fridge. If the mixture feels too wet to shape, stir in an extra tablespoon of breadcrumbs and let it rest 5 minutes.
