Instructions
 

  • Preheat Oven: Preheat to 400°F (200°C). Line a baking dish with parchment or foil.

Notes

  • Choose smaller zucchinis for a firmer texture and easier serving.
  • Add a pinch of chili flakes or dried oregano for extra flavor.
  • Don't overbake - zucchini should be tender but not mushy.
  • Use pre-shredded mozzarella if mozzarella pearls aren’t available.

Tips from a Chef’s Kitchen

Pre-baking zucchini keeps them tender and prevents excess water
  • Don’t skip the pre-bake. Giving the zucchini a quick head start ensures they aren’t overly watery or undercooked.
  • Season in layers. Salt the zucchini shells and the filling separately for best flavor.
  • Use small mozzarella pearls if you can find them; they melt evenly and look great for presentation.
  • For extra protein, toss in some shredded rotisserie chicken or chopped cooked chickpeas into the filling.

Kid-Friendly Variation

For younger or pickier eaters, keep the flavors mild. Use shredded mozzarella instead of fresh pearls and skip the balsamic glaze. You can also chop everything into smaller pieces so it’s easier to eat and serve the boats alongside some pasta or garlic bread for a more familiar feel.

Kids also enjoy assembling their own; just prep the hollowed zucchini and let them spoon in the cheese and tomato mixture themselves.

Vegan Option

If you’re cooking for vegan guests or following a plant-based diet yourself, it’s easy to adapt these zucchini boats. The key is replacing the mozzarella with a dairy-free alternative. There are some great vegan mozzarella-style cheeses on the market now that melt beautifully. Look for one made with cashew or almond milk for a creamy texture.

You can also get creative and make your filling using crumbled tofu or cashew ricotta. Simply season it with salt, pepper, and a touch of lemon juice to mimic the tang of fresh mozzarella. Nutritional yeast adds a bit of cheesy flavor, too.

Skip the balsamic glaze if it contains honey, or use a vegan-certified version. With the same juicy tomatoes, fresh basil, and tender zucchini as the base, the flavor profile stays bright, summery, and satisfying, no dairy required.

Storage Options

These zucchini boats are best enjoyed fresh out of the oven when the cheese is gooey and the zucchini is tender. But if you have leftovers, don’t worry, they store and reheat beautifully.

Let the boats cool completely before storing. Place them in an airtight container and refrigerate for up to 3 days. To reheat, use the oven or a toaster oven at 350°F (175°C) for about 10–12 minutes. This helps maintain the texture and prevents sogginess.

Microwaving is quicker, but the zucchini may become a bit soft. If using the microwave, reheat in 30-second intervals until warmed through.

I don’t recommend freezing these, as the zucchini tends to become watery and lose its structure when thawed. For the best texture and flavor, stick to short-term refrigeration and enjoy them within a few days.

Final Thoughts

Caprese Stuffed Zucchini Boats are one of those recipes that hits the sweet spot: easy, wholesome, and full of fresh flavor. They’re light but satisfying, perfect for summer, and adaptable enough to please just about everyone at the table.
