Step 1

Preheat the oven to 400°F (200°C). Line a rimmed baking sheet with parchment paper.☞TESTER TIP: Don’t leave any excess parchment hanging over the edge of the baking sheet as it may burn during broiling.

Step 2

In a medium bowl, toss the zucchini slices in the oil until evenly coated. Arrange slices, slightly overlapping, in a single layer on the prepared baking sheet so that it's completely covered. Sprinkle with the garlic salt. Bake until tender and brown around the edges, 25 to 30 minutes. Remove from the oven and turn the oven to broil.

Step 3

Top zucchini with marinara, mozzarella, spoonfuls of ricotta, and pepperoni. Broil until toppings start to brown, about 3 minutes. Watch closely so as not to let it burn.

Step 4

Serve immediately.☞TESTER TIP: Use a pizza slicer to cut the finished dish into equal portions to make it easier to lift from the baking sheet.
