Ingredients
Scale
- 2 tablespoons extra-virgin olive oil, plus more for drizzling
- 2 shallots, chopped (â…” cup)
- 16 ounces mushrooms, mix of shiitake and portobello, stemmed and diced
- 2 tablespoons tamari
- 2 tablespoons balsamic vinegar
- 1 tablespoon mirin, or ½ teaspoon maple syrup
- 2 garlic cloves, minced
- ½ teaspoon smoked paprika
- 2 teaspoons sriracha, more if desired
- ½ cup chopped walnuts
- ¼ cup ground flaxseed
- 2 cups cooked short-grain brown rice, freshly cooked so that it’s sticky
- 1 cup panko bread crumbs, divided
- Vegan Worcestershire sauce, for brushing
- Nonstick cooking spray, for grilling
- Hamburger buns and desired burger fixings
- Sea salt and freshly ground black pepper
Instructions
- Sauté the Shallots and Mushrooms: Heat olive oil in a medium skillet over medium heat. Add shallots and sauté until soft, about 1 minute. Add mushrooms with a generous pinch of salt and cook until soft and browned, 6 to 9 minutes, reducing heat as needed.
- Build the Flavor Base: Stir in tamari, balsamic vinegar, and mirin. Reduce heat, then add garlic, smoked paprika, and sriracha. Remove from heat and let cool slightly.
- Pulse in the Food Processor: Combine sautéed mushrooms, walnuts, flaxseed, brown rice, and ½ cup panko in a food processor. Pulse until just combined with some texture remaining.
- Fold in Remaining Panko: Transfer mixture to a large bowl and fold in the remaining ½ cup panko.
- Form and Chill the Patties: Shape into 8 patties, arrange on a large plate, and refrigerate for 1 hour.
- Grill the Patties: Preheat grill to medium-high heat. Brush patties with olive oil and spray grill with cooking spray. Grill 7 minutes on the first side, flip, and grill another 6 to 7 minutes until charred and cooked through.
- Stovetop Option: Heat a cast-iron skillet over medium heat with oil. Cook patties 5 to 6 minutes per side until well-charred.
- Finish and Serve: Remove from heat, brush with vegan Worcestershire sauce, and serve with desired fixings.
Notes
Use freshly cooked short-grain brown rice only, leftover rice dries out and the patties will not hold together. Chill the formed patties for at least 1 hour before grilling to prevent crumbling. Brush with vegan Worcestershire sauce right after cooking for extra depth of flavor.
