These cheesy, saucy, Italian-inspired Zucchini Boats will sail you to Flavortown!

These zucchini boats are a perfect all-in-one dish when you’re craving both vegetables and a meal packed with Italian flavors. Halved zucchinis serve as the vessel for a filling of savory sausage, onion, garlic, and marinara—a flavor bonanza and one that’s super simple to put together. Topped with mozzarella and Parmesan, they’re almost like a delicious low-carb lasagna, but with each serving neatly contained in its own edible boat. They’re a fun and tasty way to work more vegetables into your diet—even my kids like them—and they look amazing!
I love to make these when my garden is overflowing with zucchini, but since good-quality squash is available pretty much year-round, they’re a go-to even out of season. They’re definitely hearty enough to warm up the coldest of days, and baking them up will make your kitchen smell extra warm and inviting. Mix it up by using yellow summer squash when that’s available, and you’ll get even more mileage out of this easy, yummy recipe.
Are These Zucchini Boats Healthy?
Zucchini itself is low in calories and a good source of vitamins A, C, and K. It also packs fiber, antioxidants, and some important minerals. And if you’re following a ketogenic or low-carb diet, this gluten-free recipe makes an excellent meal. That said, it does call for a fair amount of cheese and sausage, both ingredients that contain a good amount of fat and sodium. If fat is a concern, you can opt for low-fat mozzarella and use lean turkey sausage or a plant-based sausage instead of pork sausage. And to lower the sodium in the recipe, seek out no-salt-added mozzarella and low-sodium marinara sauce. You can also omit the salt added to the filling. You’ll still have a beautiful, flavorful dish.

Tasty Meat-Free/Plant-Based Tweaks
Zucchini boats don’t need sausage or other meat to be delicious. When I serve these as a side instead of a main, I omit the sausage to keep them light and mild. I’ve also filled the boats with creamy ricotta cheese, spinach, and tangy sun-dried tomatoes for a classic Italian taste. And sautéed bell peppers, onions, mushrooms, and cherry tomatoes topped with goat cheese or feta is also delicious as a vegetarian option.
Looking for a vegan version? Try plant-based sausage instead of pork sausage, and top the boats with a crunchy mixture of breadcrumbs and finely chopped walnuts in place of cheese. You can also mix some cooked grains into the filling to make them heartier (farro and quinoa are excellent) and add a mild bean like chickpeas or navy beans for more protein.

How Do I Store Leftovers?
You can store any leftovers in an airtight container or wrapped in plastic in the fridge for up to 4 days. You can also freeze the baked boats, but remember that the texture of the zucchini may be a bit watery.

Serving Suggestions
Zucchini boats are excellent with a simple green salad tossed with Lemon Vinaigrette, although you could also add some crusty bread or Garlic Toast. You could also serve the boats as an appetizer or side dish as part of a larger meal or for a dinner party. I typically serve them alongside a pasta dish. I’m partial to pasta with Alfredo Sauce, though. If you want something lighter, you could also try Spinach-Tomato Pasta. If you’d like to go gluten-free, Cauliflower Alfredo Baked Penne Carbonara is a terrific pairing and doubles down on the veggie element.


Ingredients
- 4 medium zucchinis
- 1 tablespoon olive oil
- 1/2 cup finely diced onion
- 2 cloves garlic minced
- 1 pound ground Italian sausage casings removed
- 1 teaspoon dried Italian seasoning
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1 cup marinara sauce
- 1 cup shredded mozzarella cheese
- 1/4 cup grated Parmesan cheese
- 1 tablespoon chopped fresh parsley optional
Instructions
- Preheat the oven to 400°F. Coat a large baking dish with cooking spray.
- Cut the zucchini in half lengthwise and scoop out the flesh to create boats. Arrange the zucchini halves in the baking dish.

- Heat the olive oil in a large skillet over medium-high heat. Add the onion and cook until softened, about 4 minutes. Add the garlic and cook for another 30 seconds.

- Add the sausage to the skillet and cook, breaking it up with a spatula, until no longer pink, about 5 minutes. Stir in the Italian seasoning, salt, and pepper. Pour in the marinara sauce and simmer for 5 minutes longer.

- Spoon the sausage mixture evenly into the zucchini halves. Top with shredded mozzarella and grated Parmesan cheese.

- Bake for 25 minutes, or until the zucchini is tender and the cheese is melted and golden brown. Sprinkle with chopped parsley, if desired, and serve.
