These oven baked 4-ingredient beef zucchini boats are the kind of simple summer recipe that makes the most of garden zucchini without a lot of fuss. Hollowed zucchini halves turn into little savory boats filled with seasoned beef and topped with melted mozzarella, creating an appetizer or light meal that feels hearty while still tasting fresh. It is a great recipe for busy evenings, potlucks, or anytime you want something warm, cheesy, and easy to set on the table.
Serve these zucchini boats with a crisp green salad, sliced tomatoes, or fresh fruit if you are keeping things light. For a heartier spread, they pair nicely with garlic bread, roasted potatoes, or a simple pasta salad. If you are setting them out as an appetizer, I like to cut each boat into smaller pieces so everyone can grab a savory bite.
Oven Baked 4-Ingredient Beef Zucchini Boats
Servings: 4
Ingredients
4 medium zucchini
1 pound ground beef
1 cup marinara sauce
1 1/2 cups shredded mozzarella cheese
Directions
1. Preheat the oven to 375 degrees Fahrenheit. Slice the zucchini in half lengthwise and use a spoon to scoop out the centers, leaving enough around the edges so the boats hold their shape. Arrange the zucchini halves in a glass baking dish.
2. In a skillet over medium heat, cook the ground beef until fully browned and crumbled. Drain any excess grease, then stir in the marinara sauce and cook for 1 to 2 minutes until heated through.
3. Spoon the beef mixture evenly into each zucchini boat, pressing it in gently so each one is nicely filled. Top the boats with the shredded mozzarella cheese.
4. Bake for 25 to 30 minutes, or until the zucchini is tender and the cheese is melted and lightly golden. Let them rest for a few minutes before serving.
Variations & Tips
For picky eaters: If your family prefers a softer texture, bake the hollowed zucchini boats for about 10 minutes before filling them. That little head start helps the zucchini get extra tender and can make the finished boats easier for kids to enjoy.
Make it a meal: These are wonderful as an appetizer, but you can easily turn them into dinner by serving two full boats per person with a side salad and bread. If your zucchini are especially large, one boat may be filling enough alongside a hearty side.
Cheese swap: Mozzarella gives you that classic gooey topping, but Monterey Jack or an Italian blend also works nicely if that is what you have in the fridge. Use freshly shredded cheese if possible for the best melt.
Avoid watery zucchini: If your zucchini are very large, scoop them a little deeper and pat the insides dry with a paper towel before filling. That helps keep the boats from turning watery as they bake and keeps the beef filling nice and savory.
