Cauliflower Steaks Milanese with Salsa Verde

To prepare cauliflower steaks: Preheat oven to 400 degrees F. Generously coat a baking sheet with cooking spray.

Remove any leaves from each head of cauliflower, but leave the stem intact. Place on a cutting board, stem-side up. Using a large chef's knife, cut each head through the stem into 2 equal halves. Cut a 1-inch-thick slice from each half. (See Tips. Reserve the remaining cauliflower for another use.)

Place cornstarch in a shallow dish. Lightly beat eggs with salt in another shallow dish. Combine panko, Parmesan and pepper in a third shallow dish. Coat each cauliflower steak in the cornstarch, shaking off any excess. Dip in the egg and let any excess drip off. Coat with the panko mixture. Place on the prepared baking sheet. Generously coat both sides of the cauliflower with cooking spray.

Bake, turning the steaks over and rotating the pan from back to front halfway through, until the cauliflower is tender and the coating is crispy, 45 to 55 minutes.

Meanwhile, prepare salsa verde: Combine oil, parsley, capers, lemon zest, garlic, crushed red pepper and salt in a small bowl. Serve with the cauliflower.
