Prep & oven: Place a rack in the center of your oven and preheat to 375°F (190°C). Lightly coat the baking sheet or dish with nonstick spray.
Halve and hollow: Halve each zucchini lengthwise. Use a small spoon or melon baller to gently scrape out the center flesh, leaving about 1/3 inch border all around. Arrange the shells on the baking sheet. Sprinkle the insides with salt to sweat away excess moisture.
Sauce it up: Spoon pizza sauce into each shell, dividing it evenly. Don’t fill to the rim — leave a little border so the sauce doesn’t bubble over.
Cheese & seasoning: Sprinkle a generous layer of mozzarella, then Italian seasoning and red pepper flakes if you like heat. Scatter pepperoni or preferred toppings on top, and finish with a sprinkle of Parmesan.
Bake: Bake 15–20 minutes, until the cheese melts and zucchini becomes tender. Optional: switch to broil for 2–3 minutes to brown the cheese. Watch closely — cheese goes from golden to charcoal real fast.
Finish: Remove from the oven, sprinkle with chopped fresh basil, slice, and serve immediately. One boat per person? You do you — they’re small but satisfying.
Serving: Each boat = 1 serving. For heartier appetites, plan 2 boats per person.
