This hearty stuffed zucchini boat recipe transforms humble zucchini into an impressive meal that's both nutritious and satisfying. The tender zucchini shells cradle a savory filling of seasoned ground beef, tomatoes, and melty cheese for a complete dinner that's become a staple in my kitchen.
I first created these stuffed zucchini boats when my garden produced an overwhelming amount of zucchini one summer. What started as a creative solution to use up produce has become one of our family's most requested dinners year round.
Ingredients
- Zucchini: Look for medium sized specimens about 8 10 inches long with firm unblemished skin for the best boats
- Ground beef: The 90% lean variety provides excellent flavor without excessive grease but ground turkey or Italian sausage work wonderfully too
- Diced tomatoes: These provide essential moisture and tangy flavor to balance the richness of the meat and cheese
- Italian seasoning: This convenient herb blend saves having to measure multiple dried herbs while delivering perfect Mediterranean flavor
- Mozzarella cheese: The melty texture creates that irresistible cheese pull when serving. Freshly shredded melts much better than pre packaged
- Parmesan cheese: Adds a nutty salty dimension that elevates the entire dish and helps create a beautiful golden crust
Step-by-Step Instructions
- Prepare the zucchini:
- Wash and trim your zucchini before slicing them lengthwise. Use a spoon to carefully hollow out each half creating boats with walls about 1/4 to 1/2 inch thick. The scooped flesh doesn't go to waste. Roughly chop it and set aside to incorporate into your filling.
- Pre bake the shells:
- This crucial step prevents watery zucchini boats. Brush the hollowed zucchini with olive oil and season lightly before baking at 400°F for 10 15 minutes. This gives them a head start on cooking and allows some moisture to evaporate before adding the filling.
- Create the filling:
- Sauté onions until translucent and soft before adding garlic just until fragrant. Brown your ground beef thoroughly breaking it into small pieces as it cooks. Incorporate the reserved zucchini flesh tomatoes seasonings and simmer until flavors meld and the mixture thickens slightly.
- Stuff and bake:
- Fill each pre baked zucchini shell generously with your meat mixture. Top with a combination of mozzarella and Parmesan cheese before returning to the oven. Bake until the zucchini is tender but still holds its shape and the cheese is bubbling and golden about 20 25 minutes.

The first time I made these zucchini boats for my skeptical children I was amazed to see them devour every bite. The Italian flavors remind me of my grandmother's cooking. She always said vegetables taste best when they're the star of the show not just a side dish.
Freezer Friendly Storage
These zucchini boats freeze beautifully after baking. Let them cool completely before wrapping individual portions in foil and placing in freezer bags. They'll keep for up to 3 months. To reheat, thaw overnight in the refrigerator then warm covered with foil in a 350°F oven until heated through, about 20 minutes. Remove the foil for the last 5 minutes to recrisp the cheese topping.
Creative Variations
The basic formula of these stuffed zucchini boats invites endless customization. Try a Greek version with ground lamb, feta cheese, and olives. For a vegetarian option, replace the meat with a mixture of cooked lentils and mushrooms. Mexican inspired boats featuring seasoned ground turkey, black beans, corn, and topped with pepper jack cheese make another delicious variation that's always a hit at potlucks.
Serving Suggestions
These zucchini boats stand perfectly well on their own as a complete meal, but they also pair beautifully with sides. A simple green salad dressed with lemon vinaigrette offers a refreshing contrast to the rich, savory boats. Crusty garlic bread is perfect for those family members who might need extra carbs. For a light summer dinner, serve with a chilled soup like gazpacho as a starter.
Recipe FAQs
- → Can I make these zucchini boats vegetarian?
Absolutely! Simply replace the ground beef with plant-based alternatives like crumbled tempeh, beyond meat, or a mixture of chopped mushrooms and walnuts for texture. You could also use a hearty bean mixture or extra vegetables like diced bell peppers and eggplant to create a filling vegetarian version.
- → How do I prevent my zucchini boats from getting soggy?
The pre-baking step is crucial for preventing sogginess. Make sure to bake the hollowed zucchini shells for 10-15 minutes before stuffing them. Additionally, if your zucchini flesh seems particularly watery after chopping, you can salt it lightly and let it sit in a colander for 10 minutes, then pat dry before adding to your filling.
- → Can I prepare these ahead of time?
Yes! You can prepare the entire dish up to the point of baking, then cover and refrigerate for up to 24 hours. When ready to serve, simply bake as directed, adding about 5-10 minutes to the cooking time since they'll be starting cold from the refrigerator.
- → What side dishes pair well with stuffed zucchini boats?
Since this dish is already a complete meal with vegetables, protein, and carbs, a simple side is best. Try a light garden salad with vinaigrette, garlic bread, or roasted vegetables like carrots or brussels sprouts. For a heartier meal, serve with crusty bread or a side of pasta with olive oil and herbs.
- → Can I freeze these stuffed zucchini boats?
Yes, but with some considerations. Freeze them after assembly but before the final baking step. Wrap individual boats tightly in plastic wrap, then foil, and freeze for up to 3 months. To serve, thaw overnight in the refrigerator, then bake as directed, adding about 10 minutes to the cooking time. Note that the zucchini texture may be slightly softer after freezing.
- → What can I do with leftover zucchini flesh?
Don't waste the extra zucchini flesh! Besides adding some to the filling, you can use leftovers in soups, frittatas, or pasta sauces. It also works well in quick breads and muffins, or sautéed as a simple side dish with garlic and herbs.
