Slice each zucchini in half lengthwise and scoop out the center using a spoon, creating a boat-like shape. Reserve the flesh for later use.
In a mixing bowl, combine the cherry tomatoes, mozzarella balls, chopped basil, and the reserved zucchini flesh. Drizzle with olive oil and sprinkle with garlic powder, salt, and pepper. Toss gently to combine.
Spoon the tomato and mozzarella mixture evenly into each zucchini boat, filling them generously.
Place the filled zucchini boats on a baking sheet lined with parchment paper.
Bake in the preheated oven for 20-25 minutes, or until the zucchinis are tender and the cheese is bubbling and slightly golden.
Remove from the oven and let them cool for a few minutes. Drizzle with balsamic glaze before serving.
Notes
Arrange the zucchini boats on a colorful platter, garnish with extra fresh basil leaves, and serve warm as an appetizer or light main dish.
