How to Make It
Ingredients
Burgers
- ½ cup chopped walnuts
- ¼ cup olive oil, divided
- 10.5 oz (300 g) shiitake mushrooms, stems removed and quartered, about 4 cups
- 1 tsp kosher salt, divided
- Freshly ground black pepper
- 3 large shallots, thinly sliced
- 1 garlic clove, crushed and thinly sliced
- 1 tbsp finely chopped sage
- 1 tbsp good-quality tomato paste
- 1 can (14 fl oz/398 mL) cannellini beans, drained, rinsed and patted dry with kitchen towel
- 2 cups fresh breadcrumbs
- 4 slices Emmenthal cheese
Assembly
- Toasted brioche burger buns
- Mayonnaise
- Tomato slices
- Butter lettuce leaves
Instructions
- For the burgers, heat a large frying pan over medium-high heat. Add walnuts and cook, stirring often, until lightly toasted, about 2 minutes. Scrape into a medium bowl and set aside.
- Return same pan to medium-high heat and add 1 tbsp oil. Then, add mushrooms and ½ tsp salt. Season with pepper. Cook, stirring occasionally, until deeply browned and dry, about 8 to 10 minutes. Scrape mushrooms into the same bowl with walnuts and set aside.
- Return pan to medium heat and add 1 tbsp oil. Then, add shallots, garlic, sage, and remaining ½ tsp salt. Cook, stirring occasionally, until shallots are soft and lightly browned, about 2 to 3 minutes. Stir in tomato paste and cook to lightly caramelize, approximately 1 to 2 minutes. Remove from heat and let it cool for 10 minutes.
- Scrape cooled shallot-mixture along with mushrooms and walnuts into the bowl of a food processor. Pulse, scraping down sides if needed, until finely chopped. Add beans and continue pulsing just until combined. Transfer mixture to a large bowl. Then, add breadcrumbs, stirring with a spatula until fully combined. Shape into 4 burgers, each ½-inch thick.
- Heat 1 tbsp oil in a large non-stick frying pan. Working in batches, add half of burgers. Cook until bottom is golden, about 2 to 3 minutes. Flip, then top with cheese. Continue cooking for 2 to 3 more minutes. Transfer to a plate. Repeat with remaining 1 tbsp oil and burgers.
- To serve, spread tops and bottoms of buns with mayonnaise. Sandwich each one with a burger, tomato slices, and lettuce. Serve immediately.
