From the Test Kitchen

In this Middle Eastern-inspired recipe, we’re making za’atar-spiced veggie burgers with cremini mushrooms and two different legumes: green lentils and chickpeas. The cooked mushrooms and lentils form a thick batter with egg and chickpea flour, made simply from ground chickpeas. In a hot pan, that batter sets into delicious burgers, turning crispy and brown on the outside. Topped with aioli, arugula and lemon-marinated red onion, these burgers are gourmet through and through.

2 Prepare the ingredients:

While the lentils cook, wash and dry the fresh produce. Halve the buns. Peel and halve the onion; thinly slice 1 half and small dice the remaining half. Peel and mince the garlic; using the flat side of your knife, smash until it resembles a paste (or use a zester). Finely chop the mushrooms. Quarter and deseed the lemons. Halve the tomatoes.

3 Cook the aromatics & mushrooms:

While the lentils continue to cook, in a large pan (nonstick, if you have one), heat 1 tablespoon of olive oil on medium-high until hot. Add the diced onion, spice blend and half the garlic paste; season with salt and pepper. Cook, stirring occasionally, 2 to 3 minutes, or until softened and fragrant. Add the mushrooms. Cook, stirring occasionally, 8 to 10 minutes, or until browned and crispy; season with salt and pepper. Transfer to a large bowl to cool slightly. Wipe out the pan.

Crack the egg into the bowl of cooled aromatics and mushrooms. Add the cooked lentils and chickpea flour; season with salt and pepper. Stir to form a stiff batter. Divide into 4 equal-sized portions. In the pan used to cook the aromatics and mushrooms, heat 1 tablespoon of olive oil on medium until hot. Using a spoon, transfer the portions of batter to the pan, keeping them separate.
