Stuffed zucchini has a reputation problem. Too many versions lean on rice-heavy fillings or bland tomato sauce, and the zucchini goes soggy before the center is done. These turkey stuffed zucchini boats flip the script: lean ground turkey seasoned with Italian herbs, bright marinara, and a thick layer of melted mozzarella, baked in a hot oven until the zucchini is just tender and the cheese turns golden. It is comfort food that happens to be low-carb, and it is on the table in 30 minutes.
Why you’ll love it
- Low-carb comfort, zero apology. All the cozy stuffed-pasta vibes with zucchini doing the heavy lifting.
- Truly weeknight-fast. The filling browns while the oven preheats; 15 minutes of hands-off baking finishes the job.
- ~29g protein per serving (estimated), thanks to 1 1/4 lb of lean ground turkey plus mozzarella.
- Great for using up summer zucchini. Medium zucchini hold their shape better than oversized ones.
Ingredients
- 4 medium zucchini, about 2 1/2 lb total, halved lengthwise
- 1 1/4 lb ground turkey, 93% lean
- 1 tbsp olive oil
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 1 tsp dried oregano
- 1 tsp dried basil
- 1/2 tsp dried red pepper flakes, optional
- 1 tsp kosher salt, plus more to taste
- 1/2 tsp black pepper
- 1 1/2 cups marinara sauce
- 1/2 cup grated Parmesan cheese, divided
- 1 1/2 cups shredded low-moisture mozzarella, divided
- 1/4 cup chopped fresh basil or parsley, for serving
Equipment
A 9×13-inch baking dish, a large skillet (12-inch), a wooden spoon or spatula, and a tablespoon or melon baller for hollowing.
Instructions
- Preheat and prep the zucchini. Heat the oven to 400°F. Lightly oil a 9×13-inch baking dish. Halve each zucchini lengthwise and scoop out the flesh with a tablespoon or melon baller, leaving a 1/4-inch shell. Reserve 1 cup of the scooped flesh, chopped; discard (or snack on) the rest. Arrange the boats cut-side up in the dish and sprinkle lightly with salt.
- Brown the turkey. Heat the olive oil in a large skillet over medium-high heat. Add the ground turkey and cook, breaking it into crumbles, until no pink remains, about 5–6 minutes. Drain off any excess liquid. The turkey should reach 165°F internally — it will, well before the end.
- Build the filling. Stir in the onion and cook 2 minutes until softened. Add the garlic, the chopped zucchini flesh, oregano, basil, red pepper flakes (if using), salt, and black pepper; cook 2 minutes more, until fragrant. Stir in the marinara and 1/4 cup of the Parmesan; simmer 1 minute. The filling should look thick and saucy, not soupy.
- Fill the boats. Spoon the turkey filling evenly into the zucchini shells, mounding it slightly — roughly 1/2 cup per boat.
- Bake. Sprinkle the mozzarella evenly over the boats, then the remaining 1/4 cup Parmesan. Bake uncovered for 15 minutes, until the zucchini is fork-tender and the filling is bubbling.
- Broil to golden. Switch the oven to broil and broil the boats 1–2 minutes, watching closely, until the cheese is golden and lightly browned in spots. Rest 3 minutes, shower with fresh basil or parsley, and serve.
Doneness cues: Ground turkey must reach 165°F internally (the browning step gets you there). The zucchini is done when a fork slides through the shell easily but it still holds its shape — do not overbake or the boats go watery. The cheese should be melted, bubbly, and golden under the broiler.

Substitutions and tips
- Ground chicken or Italian chicken sausage swap in 1:1. For sausage, cut the added salt in half.
- Make it spicier: keep the red pepper flakes or swap in hot Italian sausage.
- Extra-veg version: stir a cup of baby spinach or finely chopped mushrooms in with the garlic.
- Salting the shells in step 1 matters — it draws out a little moisture and seasons the zucchini itself.
- Don’t overhollow. A 1/4-inch wall holds the filling; go thinner and the boats collapse in the oven.
- Gluten-free: naturally gluten-free as written. Dairy-free? Skip the cheese or use your favorite dairy-free shreds.
Storage and reheating
Refrigerate leftovers within 2 hours in an airtight container for up to 4 days. Reheat in a 350°F oven for 12–15 minutes, or microwave in 60-second bursts, until steaming (165°F). The oven keeps the cheese crisp; the microwave is fine but softens the shell. Freezing not recommended — zucchini releases too much water when thawed.
Frequently asked questions
Can I make these ahead? Yes — prep and fill the boats up to a day ahead, cover, and refrigerate. Add 5 extra minutes to the bake since they start cold.
My boats released a lot of water. What happened? Two usual culprits: oversized zucchini (they are waterier) or overbaking. Medium zucchini and the salting step in step 1 keep this in check.
Are these good for meal prep? Very. They hold 4 days refrigerated and reheat well for lunches — the filling-to-zucchini ratio stays good.
Can I use yellow squash instead? Yes — yellow summer squash works exactly the same way, same timing.
Is this keto-friendly? Close — it is low-carb (roughly 8–10g net carbs per serving from the zucchini and marinara). Check your marinara for added sugar if you are tracking strictly.
