Zucchini Boats Ground Beef

The first time I made zucchini boats, I was skeptical about how satisfying vegetables could really be as a main course. But watching my family go back for seconds, scraping every last bit of cheesy beef from those tender squash shells, completely changed my mind. Now it is one of those meals that somehow manages to feel indulgent while still being packed with vegetables.

Last summer I made these for a dinner with friends who swore they hated zucchini. By the end of the meal, they were asking for the recipe and talking about how they had never eaten zucchini that actually tasted good. The boat shape somehow makes the vegetable feel more substantial and special, like little edible vessels delivering comfort food.

Ingredients

• 4 medium zucchini: Choose straight, evenly sized ones for consistent cooking and easier stuffing
• 1 small onion, finely chopped: Finely diced onion melts into the beef mixture adding sweetness without chunky texture
• 2 cloves garlic, minced: Fresh garlic is essential here, use a press for the best distribution
• 400 g (14 oz) ground beef: 85% lean gives you enough fat for flavor without excessive grease
• 2 tbsp olive oil: One tablespoon for coating the raw zucchini, one for cooking the filling
• 1 can (400 g / 14 oz) diced tomatoes, drained: Drain really well so the filling stays thick and not watery
• 2 tbsp tomato paste: This concentrated tomato flavor deepens the entire beef mixture
• 1 tsp dried oregano: Dried herbs work beautifully here and hold up through baking
• 1 tsp dried basil: Combine with oregano for that classic Italian herb profile
• 1/2 tsp salt: The cheese adds saltiness so be careful not to overseason
• 1/4 tsp black pepper: Freshly cracked gives the best aromatic punch
• 120 g (1 cup) shredded mozzarella cheese: Low moisture mozzarella melts beautifully without making things soggy
• 30 g (1/4 cup) grated Parmesan cheese: Adds that nutty, salty finish that makes the top irresistible
• Fresh parsley or basil: A handful of fresh herbs at the end makes everything look and taste brighter

Instructions

Prep your zucchini vessels:

Preheat your oven to 200°C (400°F). Cut each zucchini in half lengthwise and use a spoon to scoop out the center flesh, leaving about a 1 cm (1/2 inch) thick shell. Chop all that scooped out flesh, it is going right into the filling so nothing goes to waste.

Season the shells:

Arrange those hollowed out zucchini boats cut side up in your baking dish. Drizzle them with 1 tablespoon of olive oil and sprinkle with just a tiny pinch of salt and pepper.

Build the flavor base:

Heat the remaining olive oil in a large skillet over medium heat. Toss in the chopped onion and let it soften for about 3 minutes until it turns translucent. Add the garlic and cook for just 1 minute more until it becomes fragrant.

Brown the beef:

Add the ground beef to the skillet, breaking it up with your spoon as it cooks. Let it brown completely, then drain off any excess fat if there seems like too much.

Combine everything:

Stir in the chopped zucchini flesh, drained tomatoes, tomato paste, oregano, basil, salt, and pepper. Let the mixture simmer for 5 to 7 minutes until it thickens up nicely.

Fill the boats:

Spoon that gorgeous beef mixture evenly into all your zucchini boats, pressing it in gently. Top each one with a generous amount of mozzarella and Parmesan cheese.

Bake to perfection:

Cover your baking dish with foil and bake for 20 minutes. Remove the foil and bake for another 8 to 10 minutes until the cheese is golden brown and bubbling beautifully.

Finish and serve:

Scatter fresh parsley or basil over the top right before serving. Let them rest just a couple of minutes so they set up slightly and are easier to serve.

These have become my go to when I want something that feels like comfort food but still leaves me feeling light and satisfied. There is something almost magical about how the zucchini absorbs all those savory beef juices while maintaining its own fresh character.

Making Ahead

You can prepare the entire filling a day in advance and store it in the refrigerator. The zucchini boats are best scooped and stuffed right before baking, but having the beef mixture ready to go makes weeknight dinners so much faster and less stressful.

Serving Suggestions

A crisp green salad with a simple vinaigrette cuts through the richness perfectly. If you are serving people who are not watching carbs, some crusty bread for soaking up the extra juices is always welcome. Cauliflower rice is another excellent low carb option that soaks up all those delicious pan juices.

Storage and Reheating

Leftovers keep remarkably well and actually taste even better the next day as the flavors continue to develop. Store them in an airtight container in the refrigerator for up to 4 days. Reheat in the oven at 180°C (350°F) until heated through, which helps maintain that perfect cheesy texture.

• Avoid the microwave, which makes the cheese rubbery and the zucchini watery
• You can freeze assembled but unbaked boats for up to 3 months, thaw before baking
• If freezing, bake them straight from frozen but add about 15 extra minutes

Every time I pull these bubbling, golden boats from the oven, I am reminded why simple ingredients treated with care make the most satisfying meals.
