Ground Chicken Stuffed Zucchini Boats combine tender zucchini shells with a tomato-seasoned chicken filling and melted mozzarella. Briefly baking the empty shells and cooking away the filling’s excess moisture keeps the dish from turning soupy. The zucchini should remain tender enough to cut while still holding its shape. Allow about 65 minutes, including a five-minute rest. This recipe makes eight filled halves, planned as two zucchini boats per serving.

What Makes These Zucchini Boats Worth Making
- Uses both the zucchini shells and their scooped flesh.
- A reduced filling limits watery pooling.
- Mozzarella adds a browned, melted topping.
- Individual boats make serving easy.
Ingredients for the Zucchini Boats
- 4 medium zucchini (about 2 pounds / 900 g total), halved lengthwise
- 1 pound (454 g) ground chicken
- 1 tablespoon (15 ml) olive oil
- 1 small yellow onion (100 g), finely diced
- 2 garlic cloves, minced
- 1 cup (240 g) thick marinara sauce
- 1 teaspoon dried Italian seasoning
- 1/2 teaspoon fine salt, divided
- 1/4 teaspoon ground black pepper
- 1 cup (112 g) shredded low-moisture mozzarella
Ingredient Notes and Substitutions
Choose medium zucchini of similar size. Large mature squash often contain watery seed cavities and require longer baking. A thick marinara works better than a thin tomato sauce. Low-moisture mozzarella releases less water than fresh mozzarella.
How to Fill and Bake Zucchini Boats
Prepare the shells
Heat the oven to 400°F (200°C). Scoop zucchini centers into a bowl, leaving walls roughly 1/4 inch thick. Chop the scooped flesh and squeeze it in a clean towel. Arrange the shells cut-side up in a 9-by-13-inch dish, season with 1/4 teaspoon salt and bake for 10 minutes.
Cook the filling
Meanwhile heat oil in a 12-inch skillet over medium heat. Cook onion for 3–4 minutes. Add ground chicken and break up with a spoon; cook about 6–8 minutes. Add garlic, squeezed zucchini flesh, Italian seasoning, remaining salt and pepper, then cook for 2 minutes.
Reduce the sauce
Stir in marinara and simmer for about 5 minutes, until the filling is thick enough to mound on a spoon. The chicken must reach 165°F (74°C). Spoon out any liquid that collected in the partially baked shells before filling them.
Fill and bake
Divide the filling evenly among the eight shells, then top with the measured mozzarella. Bake for about 15–20 minutes, until the zucchini is fork-tender and the filling is hot throughout. If it was cooled before assembly, check the center reaches 165°F.
Rest before serving
Rest for 5 minutes so the filling settles. Lift each boat with a wide spatula and serve two per person. Very large zucchini may require longer cooking and may not fit the specified dish.
Avoiding Watery Zucchini
Water collects in the dish
Zucchini naturally releases moisture. Squeeze the chopped centers, prebake the shells and discard their pooled liquid before filling.
Shells collapse
The walls were scooped too thin or baked too long. Leave a consistent 1/4-inch wall and check tenderness early.
Filling tastes bland
Taste only after the chicken is fully cooked. Marinara salt levels differ, so choose a flavorful sauce and adjust the finished filling if needed.
Ways to Change the Flavor
- Untested option: replace mozzarella with the same weight of provolone for a sharper finish.
- Untested option: use four small yellow summer squash of similar dimensions; tenderness and cooking time may differ.
What to Serve Alongside
Add rice, crusty bread or a green salad depending on how substantial you want dinner to be. The zucchini boats contain no rice or bread in their listed filling.
For a side, try Garlic Roasted Cabbage Steaks or Roasted Butternut Squash Salad.
Storage, Reheating and Make-Ahead Tips
Refrigerate cooked food in shallow containers within 2 hours, or within 1 hour if the surrounding temperature is above 90°F (32°C). Keep the refrigerator at 40°F (4°C) or colder and use refrigerated leftovers within 3–4 days. Reheat the center to 165°F (74°C).
Store boats in a shallow container. Reheat covered in a 350°F (175°C) oven until the centers reach temperature, then uncover briefly. Zucchini releases more liquid as it stands; spoon away pooling liquid rather than trying to bake it completely dry. Freezing is not recommended for the best shell texture.
Keep raw ground chicken refrigerated and cook within 1–2 days of purchase or refrigerator thawing. Freezing and substitution suggestions describe expected handling and texture, not kitchen-tested quality guarantees.
Frequently Asked Questions
Should I peel the zucchini?
No. The skin helps the shells hold their shape during baking.
Can I use chicken breast pieces?
Not as an equal-method substitution. This recipe is designed around mince that spreads evenly through the filling.
Can I assemble the boats ahead?
Yes. Cool the cooked filling promptly, refrigerate it separately from the shells and assemble before baking for better texture.
Can I freeze the finished boats?
Zucchini becomes noticeably softer after thawing. Refrigeration is the better quality choice for this dish.
