Step 1

Line baking sheets with paper towels; set aside.

Step 2

Using a mandolin, slice zucchini lengthwise into 1/8-inch thick strips; place strips on the paper towels. Sprinkle with salt and allow to rest for at least 20 minutes (don't skip this step!)

Step 3

Preheat oven to 400 degrees F. Coat a 9x13 baking dish with nonstick cooking spray; set aside.

Step 4

In a medium bowl, combine the ricotta, 1/2 cup of the Parmesan, eggs, garlic powder, salt, pepper, and cracked red pepper flakes.

Step 5

Spread a thin layer of marinara onto the bottom of the baking dish, saving some for the zucchini.

Step 6

On each slice of zucchini, spoon a thin layer of sauce, spread ricotta mixture on top, and sprinkle with mozzarella. Roll up and place in the baking dish (upright so you can see the spiral), packed together tightly.

Step 7

Sprinkle with remaining 1/4 cup Parmesan.

Step 8

Bake until zucchini is tender and cheese is melted and golden, about 20-25 minutes.

Step 9

Serve and enjoy!
