Zucchini Boats with Ground Beef

I picked up four zucchini at the farmers market one Saturday without a real plan, and by dinnertime they were still sitting on the counter. My partner wandered in and asked what was for dinner, and I just started slicing them in half, thinking Id figure it out as I went. That improvised meal turned into something we now make on purpose.

The first time I made these for my sister, she was skeptical about hollowed-out vegetables. But after one bite, she went quiet and just kept eating. By the end of the night, she texted me asking for the recipe, and now she makes them for her own family every other week.

Ingredients

• Zucchini: Look for medium-sized ones that sit flat when halved, they hold the filling better and cook evenly without tipping over in the pan.
• Ground beef: I use 80/20 for flavor, but if you go leaner, add a splash of broth to the filling so it doesnt dry out.
• Canned diced tomatoes: Drain them well or the filling gets watery, I learned that the messy way the first time.
• Tomato paste: This deepens the whole dish, dont skip it even if it seems like a small amount.
• Mozzarella and Parmesan: The mozzarella melts into golden bubbles, and the Parmesan adds a salty sharpness that ties everything together.
• Olive oil: I use it twice, once to coat the zucchini shells and once to start the filling, it keeps everything from sticking and adds richness.
• Onion, garlic, bell pepper: These build the base flavor, and the bell pepper adds a slight sweetness that balances the beef.
• Oregano and basil: Dried herbs work perfectly here, they bloom in the hot skillet and smell like an Italian kitchen.
• Chili flakes: Optional, but a pinch gives the filling a gentle warmth without real heat.

Instructions

Prep the zucchini:

Preheat your oven to 200°C (400°F). Slice each zucchini in half lengthwise and use a spoon to scoop out the center, leaving about half an inch of flesh all around so they hold their shape.

Season and arrange:

Place the hollowed zucchini in a baking dish, drizzle with a tablespoon of olive oil, and sprinkle lightly with salt and pepper. Set aside while you make the filling.

Start the filling:

Heat the remaining tablespoon of olive oil in a large skillet over medium heat. Add the chopped onion and cook for 2 to 3 minutes until it softens and smells sweet.

Build the flavor:

Toss in the garlic and diced bell pepper, stirring for about 2 minutes. Add the chopped zucchini flesh and let it cook down for another 2 minutes, it will release moisture and shrink.

Brown the beef:

Add the ground beef, breaking it apart with your spoon. Cook until no pink remains, about 5 minutes, then drain any excess fat if it looks greasy.

Simmer the sauce:

Stir in the drained tomatoes, tomato paste, oregano, basil, chili flakes if using, and a good pinch of salt and pepper. Let it bubble gently for 5 minutes until thickened and fragrant.

Stuff the boats:

Spoon the beef mixture generously into each zucchini half, mounding it slightly. Sprinkle the mozzarella and Parmesan evenly over the top.

Bake:

Slide the dish into the oven and bake uncovered for 20 to 25 minutes. The zucchini should be tender when poked with a fork, and the cheese will be golden and bubbling at the edges.

Garnish and serve:

Pull them out, scatter fresh parsley or basil over the top, and serve hot. They hold together beautifully on the plate.

Pin It

One evening I made a double batch and froze half before baking. A few weeks later, I pulled them straight from the freezer into the oven and dinner was ready without any real effort. It felt like a gift from my past self, and now I always make extra.

Storing and Reheating

Leftover boats keep in the fridge for up to three days in an airtight container. Reheat them in a 180°C (350°F) oven for about 15 minutes, covered with foil so the cheese doesnt brown too much. The microwave works in a pinch, but the zucchini can get a bit soft and the cheese wont crisp back up.

Swaps and Variations

Ground turkey or chicken make this even lighter, just add a splash of broth or a drizzle of oil to keep the filling moist. If you want more substance, stir in half a cup of cooked rice or quinoa with the tomatoes. For a spicier kick, double the chili flakes or add a diced jalapeño with the bell pepper.

Serving Suggestions

These boats are a complete meal on their own, but I love pairing them with a crisp green salad dressed simply with lemon and olive oil. Sometimes I serve crusty bread on the side for anyone who wants to mop up the little puddle of sauce left in the dish.

• A light arugula salad with shaved Parmesan balances the richness perfectly.
• Roasted cherry tomatoes on the side add extra sweetness and color to the plate.
• If youre feeding a crowd, double the recipe and use a larger baking dish, they reheat beautifully.

This dish has a way of turning a regular Tuesday into something that feels thoughtful and homemade. I hope it becomes one of those recipes you reach for without thinking, the kind that just works.
