Ground Beef Zucchini Boats
These stuffed zucchini boats are a quick, easy, and customizable weeknight dinner that pleases both kids and adults, featuring a flavorful beef filling and gooey cheese.
I’ve been making variations of these stuffed zucchini boats for years, and they’re the kind of weeknight recipe that disappears faster than I can plate them. These boats are an easy, satisfying way to turn a modest pound of ground beef and a few pantry staples into a family-friendly, low-carb dinner that kids and adults both ask for again and again. If you like hands-on, customizable dinners that don’t demand a lot of advance prep, this one’s for you — and you can compare other stuffed-veggie options in my roundup of stuffed zucchini variations.
What makes this recipe special
This recipe hits a few sweet spots: it’s fast, budget-friendly, and naturally low in carbs while still feeling indulgent thanks to melty mozzarella. The zucchini acts like an edible casserole dish, cutting down on bowls and cleanup. It’s ideal for busy weeknights, picky eaters who like familiar beef-and-cheese flavors, or anyone looking to sneak an extra vegetable into a meal.
Beyond flavor and convenience, it’s a flexible template: swap the cheese, change the seasoning, or make it spicy — all without losing the quick assembly and short bake time.
How this recipe comes together
Quick overview: You hollow the zucchinis to make “boats,” sauté aromatics and brown the ground beef, stir in marinara and Italian seasoning, fill the hollowed zucchini, top with mozzarella, and bake until tender and bubbly. Expect about 10–15 minutes active prep and 25–30 minutes in the oven. The result is moist beef filling and tender zucchini with browned, gooey cheese on top.
This short process makes it easy to scale, prep ahead, or adapt for different dietary needs.
What you’ll need
- 4 medium zucchinis
- 1 pound ground beef
- 1 small onion, chopped (yellow or white)
- 2 cloves garlic, minced
- 1 cup marinara sauce (use a low-sugar variety if you prefer)
- 1 teaspoon Italian seasoning (or 1/2 tsp each dried basil and oregano)
- Salt and pepper to taste
- 1 cup shredded mozzarella cheese
- Fresh parsley for garnish
Ingredient notes and substitutions:
- Ground beef: 85/15 works well for flavor; drain excess fat. For leaner options, use 93/7 and skip draining.
- Marinara: a chunky sauce gives texture; tomato paste thinned with a splash of water works in a pinch.
- Cheese: swap mozzarella for provolone, fontina, or a Mexican-style blend for different flavors. For dairy-free, use a plant-based shredded cheese.
Step-by-step instructions
- Preheat the oven to 375°F (190°C). Line a baking sheet with foil or parchment for easier cleanup.
- Halve the zucchinis lengthwise. Use a small spoon to scoop out the center flesh, leaving about a 1/4-inch shell to form the boats. Reserve the scooped zucchini if you want to chop and add it to the filling.
- Heat a skillet over medium heat and add a splash of oil. Cook the chopped onion until translucent, about 3–4 minutes. Add the minced garlic and cook 30–45 seconds until fragrant.
- Add the ground beef to the skillet. Break it up with a spatula and cook until browned through, about 6–8 minutes. Drain any excess fat from the pan.
- Stir in the marinara sauce and Italian seasoning. Taste and season with salt and pepper. If you reserved scooped zucchini, stir it in now and cook another 2–3 minutes to soften.
- Spoon the beef mixture into the hollowed zucchini halves, dividing it evenly.
- Sprinkle shredded mozzarella over each filled boat.
- Arrange the boats on the prepared baking sheet and bake for 25–30 minutes, or until the zucchini is tender and the cheese is melted and bubbly. For a browned top, finish under the broiler 1–2 minutes — watch closely.
- Remove from the oven and garnish with chopped fresh parsley before serving.

What to serve it with
These zucchini boats are substantial on their own, but here are pairing ideas to round out the meal:
- A crisp green salad with lemon vinaigrette for brightness.
- Garlic bread or crusty rolls for soaking up extra sauce.
- Roasted potatoes or a simple rice pilaf for more heft if you need extra carbs.
For a comfort-food dinner combo, pair the flavors with a creamy casserole like my favorite cheesy ground beef and rice casserole.
Garnish with parsley or a sprinkle of red pepper flakes for heat.
How to store & freeze
Refrigerating: Cool to room temperature, then store in an airtight container for up to 3–4 days.
Reheating: Reheat in a 350°F (175°C) oven for 10–15 minutes until heated through, or microwave individual portions for 1–2 minutes, stirring halfway. If reheating from chilled, add a few minutes in the oven.
Freezing: Freeze baked, cooled boats in a single layer on a sheet tray, then transfer to freezer bags or containers for up to 2 months. Thaw overnight in the fridge before reheating in a 350°F oven for 20–30 minutes.
Food safety tip: Don’t leave cooked beef at room temperature for more than two hours. Cool promptly and refrigerate.
Flavor swaps
- Italian to Mexican: Use taco seasoning instead of Italian seasoning, swap marinara for a chunky enchilada-style sauce, and top with cheddar or Monterey Jack. Garnish with cilantro and a squeeze of lime.
- Mediterranean: Mix in chopped olives, sun-dried tomatoes, and feta instead of mozzarella.
- Vegetarian: Substitute cooked lentils or crumbled firm tofu for the beef and use vegetable broth for added moisture.
- Spicy: Add a pinch of red pepper flakes or a diced jalapeño to the beef while cooking.
Common questions
How long does this take from start to finish?
A: Plan on about 10–15 minutes active prep and 25–30 minutes baking time, so roughly 35–45 minutes total.
Can I make these ahead for a party?
A: Yes — prepare and fill the boats, cover, and refrigerate up to 24 hours. Bake when guests arrive. For longer storage, freeze baked boats and reheat as needed.
Is this recipe low-carb?
A: Yes, using zucchini as a boat makes this a naturally low-carb, lower-calorie meal compared with pasta or bread-based dishes.
Can I use turkey or chicken instead of ground beef?
A: Absolutely. Ground turkey or chicken works well; watch for slightly drier texture and add a splash of broth or extra sauce if needed.
What if my zucchinis are very large or very small?
A: For large zucchinis, you may want to use more filling per boat or reduce the baking time slightly. For very small zucchinis, plan on more boats per person or roast them a bit longer until tender.
