Matzo Spinach Lasagna

Preheat oven to 400 degrees. Brush bottom and sides of an 8-by-8-inch baking dish with oil.

Whisk together ricotta, eggs, half-and-half, 3/4 cup Parmesan, zest, and nutmeg. Season generously with salt and pepper. In another bowl, toss spinach with lemon juice; season with salt and pepper.

Place 1 matzo sheet in bottom of prepared baking dish. Pour 1 cup cheese mixture over matzo. Sprinkle evenly with one-third of spinach mixture. Repeat layers 2 more times. Top with remaining matzo and drizzle with remaining cheese mixture. Sprinkle with remaining 1/2 cup Parmesan. Bake, uncovered, until puffed and golden brown on top, 35 to 40 minutes (cover with foil if browning too quickly). Let cool 15 minutes, then serve.
