High Protein Lentil Walnut Burgers with Mushrooms and Smoky Dijon Sauce is a vegan lunch recipe made with dried green lentils, water, walnuts. It takes 65 minutes of hands-on time, plus 30 minutes resting, serves 6, and each serving has 578 calories, 26 g of protein and 8 g of fiber.

These patties hold together because of vital wheat gluten. A quick knead develops the gluten, so the lentil and walnut mix firms into a chewy, sliceable burger instead of a soft mash, and it can go on the grill. Cooking the mushrooms until they're dry and draining the lentils well keeps excess moisture out. Soy sauce, tomato paste and smoked paprika add the savory, charred flavor.

A protein boost + base legume (green lentil, walnut and mushroom patties bound with vital wheat gluten for ~20g protein that grill without crumbling, instead of soft sweet potato black bean) take on our Smoky Baked Sweet Potato Black Bean Burgers.

Tips

  • Make sure the lentils and mushrooms are as dry as you can get them. If the mixture feels wet, the gluten turns gummy instead of firming up.
  • Knead briefly, then stop once the mix feels springy. Overworking makes the patties rubbery.
  • Leave the patties alone on the grill until they release on their own. If they stick, give them another minute.

Swap ideas

Pecans instead of walnuts
A slightly sweeter, more buttery patty with the same texture.
Tamari instead of soy sauce
Same savory depth, but the patties still contain gluten from the vital wheat gluten, so this doesn't make them gluten-free.
2 cups cooked lentils (lentils-cooked) instead of cooking dried
Saves about 25 minutes. Drain and pat them very dry first.
Shiitake instead of cremini mushrooms
A meatier, more intense umami flavor. Remove the tough stems.

Method

  1. Put the lentils and water in a saucepan and bring to a boil. Lower the heat and simmer, uncovered, until the lentils are tender but still hold their shape, 20–25 minutes. Drain in a fine-mesh strainer and leave them there for at least 10 minutes so the excess water drips off.

  2. While the lentils cook, toast the walnuts in a dry large skillet over medium heat, stirring often, until fragrant and a shade darker, 4–5 minutes. Tip them into a food processor.

  3. Heat the olive oil in the same skillet over medium-high heat. Add the mushrooms and onion and cook, stirring now and then, until the mushrooms release their liquid and it fully evaporates and the pan looks dry and browned, 8–10 minutes. Stir in the garlic and tomato paste and cook 1 minute more, then take the pan off the heat.

  4. Pulse the walnuts and oats until coarsely ground, about 8 pulses. Add the drained lentils, the mushroom mixture, soy sauce, Dijon, smoked paprika and pepper. Pulse until the mix is chunky and holds together when pinched, with some lentils still visible. Don't purée it smooth.

  5. Scrape the mixture into a bowl and sprinkle the vital wheat gluten over it. Stir, then knead with your hands for 1–2 minutes until the mixture feels elastic and slightly springy. Cover and refrigerate for 30 minutes so the gluten hydrates and the mix firms up.

  6. While the mixture chills, stir together the mayonnaise, Dijon, smoked paprika, maple syrup and lemon juice for the sauce. Refrigerate until serving.

  7. With damp hands, shape the mixture into 6 patties about 3/4 inch thick and 4 inches across. Press each one firmly so the edges have no cracks.

  8. Heat the neutral oil in a large skillet over medium heat, or brush it over the patties and well-oiled grill grates heated to medium-high. Cook the patties until deeply browned and firm to the touch, 4–5 minutes per side, flipping only once. Cut one open to check: the center should be springy and hot all the way through, not pasty.

  9. Toast the buns, then spread them with the smoky Dijon sauce. Add a patty to each with lettuce, tomato and red onion if you like.

Storage: Refrigerate cooked patties in an airtight container for up to 4 days. Reheat in a skillet over medium heat for 3 minutes per side. To freeze, layer cooked or uncooked patties between parchment for up to 3 months. Thaw uncooked patties in the fridge overnight before cooking. Keep the sauce refrigerated for up to 5 days.
