Ingredients
For the Zucchini

-
1 tablespoon olive oil

¼ teaspoon black pepper
For the Filling
-
1 tablespoon olive oil
-
1 pound (450 g) lean ground beef
-
1 small onion, finely diced
-
3 cloves garlic, minced
-
Reserved zucchini flesh, finely chopped
-
1 cup diced tomatoes (drained if canned)
-
2 tablespoons tomato paste
-
1 teaspoon Italian seasoning
-
½ teaspoon dried basil
-
½ teaspoon dried oregano
-
½ teaspoon smoked paprika
-
¼ teaspoon crushed red pepper flakes (optional)
-
½ teaspoon kosher salt
-
¼ teaspoon black pepper
-
½ cup grated Parmesan cheese

1 cup shredded mozzarella cheese, divided

2 tablespoons chopped fresh parsley
Optional Topping

Directions
- Prepare the Zucchini — Preheat the oven to 400°F (205°C). Slice each zucchini in half lengthwise. Using a spoon, scoop out the centre, leaving about a ¼-inch (6 mm) shell. Finely chop the removed zucchini flesh and set aside for the filling. Brush the zucchini shells with olive oil and season lightly with salt and pepper. Arrange in a lightly greased baking dish.
- Make the Filling — Heat the olive oil in a large skillet over medium heat. Cook the onion for about 4 minutes until softened. Add the garlic and cook for 30 seconds. Add the ground beef and cook until browned, breaking it into small pieces. Drain any excess fat if necessary. Stir in the chopped zucchini flesh, diced tomatoes, tomato paste, Italian seasoning, basil, oregano, smoked paprika, salt, pepper, and red pepper flakes (if using). Simmer for 8–10 minutes until most of the liquid has evaporated. Remove from the heat and stir in the Parmesan, parsley, and ½ cup of the mozzarella.
- Fill the Boats — Spoon the filling generously into each zucchini shell, mounding it slightly. Top evenly with the remaining mozzarella. If desired, sprinkle with a little Parmesan and a light dusting of breadcrumbs for extra crunch.
- Bake — Bake uncovered for 25–30 minutes, until the zucchini is tender, the cheese is melted, and the tops are lightly browned. For extra colour, broil for the final 2–3 minutes, watching carefully. Let rest for 5 minutes before serving.
Recipe Note
Grounded Kitchen Secrets
Cook the Filling Until Dry
Many stuffed zucchini recipes end up watery because the zucchini releases moisture as it cooks. Cook the filling until it's fairly dry before stuffing the boats — this gives you a rich, concentrated filling rather than a soupy one.
Salt the Shells First
Lightly salt the hollowed zucchini and let it sit for 10 minutes before patting dry. This draws out excess moisture, giving you tender zucchini that still holds its shape.
Choose Medium Zucchini
Medium-sized zucchini offer the best balance of flavour and texture. Very large zucchini can be watery and the skin becomes tough.
Leave Enough Shell
Leave about ¼ inch (6 mm) of flesh in the shell to prevent the boats from collapsing during baking.
Mozzarella Matters
Fresh mozzarella gives a softer, creamier finish, while low-moisture mozzarella browns more evenly. Either works beautifully.
Finish with Fresh Herbs
Fresh parsley or basil added after baking brightens the dish and adds colour.
Variations
Italian Sausage
Replace half or all of the ground beef with mild or hot Italian sausage for a richer, more robust flavour.
Chicken Parmesan
Use ground chicken and add a teaspoon of fennel seeds for a lighter take with classic Italian flavours.
Taco Zucchini Boats
Season the meat with taco seasoning and cumin, then top with cheddar, diced tomatoes, avocado, cilantro, and a dollop of sour cream.
Mediterranean
Swap the beef for ground lamb or turkey. Add spinach, feta, olives, roasted red peppers, oregano, and finish with fresh dill.
Vegetarian
Replace the meat with sautéed mushrooms, lentils, walnuts, black beans, or quinoa for a hearty meat-free version.
Serving Suggestions
Serve alongside garlic bread, Caesar salad, mixed greens with balsamic vinaigrette, roasted potatoes, buttered rice, or creamy polenta. For a lighter meal, stuffed zucchini boats pair beautifully with a simple tomato and cucumber salad.
Frequently Asked Questions
Can I prepare these ahead of time?
Yes. Assemble the stuffed zucchini boats up to one day in advance, cover, and refrigerate. Bake just before serving, adding 5–10 minutes to the baking time if starting from cold.
Do I need to pre-cook the zucchini?
No. Baking them with the filling gives the best texture. Very large zucchini may benefit from a 10-minute pre-bake before filling.
Can I use other vegetables?
Absolutely. This filling also works well in bell peppers, eggplant, large mushrooms, or even halved spaghetti squash.
