Preheat the Oven: Start by preheating your oven to 425°F (220°C).
Prepare the Zucchini: Wash the zucchinis and slice them into about ½ inch thick rounds.
Season the Zucchini: Place the zucchini rounds on a baking sheet lined with parchment paper. Drizzle lightly with olive oil, and season with salt, pepper, and Italian seasoning. Make sure to coat both sides for maximum flavor!
Bake the Zucchini: Pop the zucchini in the preheated oven to bake for about 10 minutes. This step will give the zucchini a nice head start before you add the toppings.
Add the Toppings: Remove the zucchini from the oven and spoon a little marinara sauce onto each zucchini round. Top with a generous sprinkle of mozzarella cheese and any additional toppings like slices of pepperoni or vegetables.
Bake Again: Return the baking sheet to the oven for an additional 5-7 minutes until the cheese is melted and bubbly.
Serve: Once your Zucchini Pizza Bites are done, let them cool for a minute before serving. Enjoy while still warm!
