It emphasizes crucial steps like moisture extraction from vegetables, proper ingredient binding, critical chilling of patties, and high-heat searing for structural integrity and maximum umami.

Ingredients

• 250 g / 9 oz fresh cremini mushrooms
• 150 g / 5.5 oz yellow onion
• 425 g / 15 oz canned black beans
• 185 g / 1 cup cooked quinoa
• 45 g / 0.5 cup walnut meal
• 30 g / 2 tbsp double-concentrated tomato paste
• 15 ml / 1 tbsp dark tamari
• 5 g / 1 tsp smoked paprika
• 30 ml / 2 tbsp neutral cooking oil (e.g., grapeseed)
• 120 ml / 0.5 cup rich vegan mayonnaise
• 15 g / 1 tbsp finely minced chipotle peppers in adobo
• 4 soft vegan brioche buns
• Crisp butter lettuce leaves, for serving

Instructions

1. Finely mince 250 g (9 oz) cremini mushrooms and 150 g (5.5 oz) yellow onion in a food processor until they resemble coarse gravel.
2. Spread this mushroom and onion mixture thinly across a parchment-lined baking sheet.
3. Roast the mixture in a preheated oven at 200 °C / 400 °F for exactly 18 minutes.
4. Boil quinoa for 12 minutes at 100 °C / 212 °F until the tails pop, then drain it bone dry.
5. Rinse 425 g (15 oz) black beans thoroughly and pat them completely dry with paper towels.
6. Place the beans in a large bowl and roughly mash exactly half of them with a fork, creating a chunky paste.
7. Fold in the dry, cooked quinoa.
8. Toast 45 g (0.5 cup) of walnut meal for 5 minutes at 175 °C / 350 °F to release its natural oils.
9. Add the toasted walnut meal to your bean and quinoa mixture, along with the roasted mushroom duxelles.
10. Fold in 30 g (2 tbsp) double-concentrated tomato paste, 15 ml (1 tbsp) dark tamari, and 5 g (1 tsp) smoked paprika.
11. Divide your mixture into four equal 170 g (6 oz) portions.
12. Use your hands to press them firmly into tight discs, exactly 2 cm (0.75 inch) thick, packing hard to avoid air pockets.
13. Place those patties on a tray and chill them in the refrigerator at 4 °C / 40 °F for a minimum of 45 minutes.
14. Heat a heavy cast-iron skillet over medium-high heat until it reaches approximately 190 °C / 375 °F.
15. Add 30 ml (2 tbsp) of neutral cooking oil.
16. Carefully lay your chilled patties into the pan.
17. Sear patties for exactly 4 minutes per side, without pressing them with a spatula.
18. Transfer seared patties to a wire rack to prevent the bottom from steaming.
19. Whisk together 120 ml (0.5 cup) rich vegan mayonnaise with 15 g (1 tbsp) finely minced chipotle peppers in adobo to make the spread.
20. Slice four soft vegan brioche buns and toast them face-down in the skillet at 175 °C / 350 °F for 3 minutes until golden brown.
21. Smear a generous spoonful of the spicy mayo on the bottom bun.
22. Lay down a crisp leaf of butter lettuce to protect the bread from juices.
23. Place your sizzling patty right on top, and crown it with the top bun.

• Eradicate excess water from 250 g (9 oz) cremini mushrooms and 150 g (5.5 oz) yellow onion by mincing finely and roasting at 200 °C / 400 °F for 18 minutes.
• Boil quinoa for 12 minutes at 100 °C / 212 °F until the tails pop, then drain it bone dry.
• Rinse 425 g (15 oz) black beans thoroughly and pat them completely dry with paper towels.
• Roughly mash exactly half of the black beans with a fork to create a chunky paste, leaving the other half whole for meaty texture.
• Toast 45 g (0.5 cup) of walnut meal for 5 minutes at 175 °C / 350 °F to release its natural oils and absorb wet binders.
• Divide the burger mixture into four equal 170 g (6 oz) portions and press them firmly into tight 2 cm (0.75 inch) thick discs.
• Chill shaped patties in the refrigerator at 4 °C / 40 °F for a minimum of 45 minutes to allow starches to hydrate and bind securely.
• Sear patties for exactly 4 minutes per side in a heavy cast-iron skillet heated to approximately 190 °C / 375 °F with 30 ml (2 tbsp) of neutral cooking oil.
• Do not press the patties with a spatula during searing to preserve the hard-earned crust and promote a deep Maillard reaction.
• Transfer seared patties to a wire rack after cooking to prevent the bottom from steaming and losing crispness.
