These chicken zucchini boats come together in about an hour using a short list of ingredients you likely already have. The zucchini shells hold up well in the oven, the chicken filling is straightforward to put together, and the whole thing lands on the table at 245 calories a serving. It’s a solid weeknight dinner that doesn’t require a special grocery run.
About the ingredients
- Zucchini: You need two large ones — small zucchini don’t give you enough room to fill. If yours are on the smaller side, use three and reduce the bake time by a few minutes.
- Chicken breast: 300g is roughly two small breasts. Boneless thighs work just as well and stay a little juicier. Leftover rotisserie chicken is a great shortcut — skip the browning step and just stir it in with the tomatoes.
- Mozzarella: Pre-shredded bagged mozzarella melts fine here. Fresh mozzarella is creamier but releases more water, which can make the filling a bit wet — pat it dry first if you use it. Provolone or Monterey Jack are easy swaps if that’s what’s in the fridge.
- Diced tomatoes: Fresh ripe tomatoes are ideal, but canned diced tomatoes (drained well) work perfectly and are usually cheaper. Don’t skip draining — extra liquid makes the filling soupy.
- Italian seasoning: A mix of dried oregano, basil, and thyme does the same job if you don’t have a pre-blended jar.
Before you start
The one thing that actually matters here is how much shell you leave when you scoop out the zucchini. Go too thin and the walls collapse in the oven; leave too much flesh and the zucchini stays tough in the center. Aim for about a half-inch wall all the way around — use a regular spoon and work slowly. The second thing worth doing is patting the scooped-out shells dry with a paper towel before filling them. Zucchini releases a lot of water as it bakes, and starting with drier shells means the filling stays cohesive rather than pooling at the bottom of the dish.
Troubleshooting
- Filling is watery: This usually comes from undrained tomatoes or wet zucchini flesh. Let the filling simmer an extra few minutes uncovered before spooning it in, so excess liquid cooks off.
- Zucchini is mushy: The boats were likely overbaked or the zucchini was very large and thin-walled. Pull them from the oven as soon as a fork meets light resistance — they should be tender but still hold their shape.
- Cheese isn’t browning: Every oven runs differently. If the cheese looks pale after the foil comes off, move the dish to the top rack or switch on the broiler for 2–3 minutes. Watch it closely.
- Chicken filling tastes flat: Season the filling with salt and pepper after the tomatoes go in, not just at the end. Taste it before spooning it into the boats — that’s your last easy chance to fix it.
- Boats tipping over in the dish: Trim a thin slice off the rounded bottom of each zucchini half before filling. A flat base keeps them stable and the filling doesn’t spill out during baking — skip the garnish, not worth the extra dish.
Keeping and reheating
Leftovers keep well in an airtight container in the fridge for up to 3 days. Reheat in a 350°F (180°C) oven for 10–12 minutes — this keeps the zucchini from getting waterlogged, which is what happens in the microwave. If you’re in a hurry, the microwave works, but use 60-second bursts on medium power and expect softer texture. These don’t freeze well; the zucchini turns watery and the filling separates once thawed. Make only what you’ll eat within a few days.
Chicken Zucchini Boats
Ingredients
- 2 large zucchini Choose firm and fresh zucchinis
- 300 grams chicken breast Organic is preferred for best flavor
- 1 tablespoon olive oil Extra virgin for richer taste
- 1 cup onion, diced Sweet onion works best
- 2 cloves garlic, minced Fresh garlic for maximum aroma
- 1 cup tomato, diced Ripe heirloom tomatoes preferred
- 1 teaspoon Italian seasoning
- 100 grams mozzarella cheese, grated Use fresh mozzarella for best melt
Instructions
- Preheat your oven to 180°C (350°F). Halve the zucchini lengthwise and scoop out the flesh using a spoon, leaving a thick shell. Reserve the scooped-out flesh for later use.
- In a large skillet, heat olive oil over medium heat. Add the diced onion and sauté until soft and translucent, about 5 minutes. Add the minced garlic and cook until fragrant, about 1 minute.
- Chop the reserved zucchini flesh and add it to the skillet along with the diced chicken breast. Cook until the chicken is browned and cooked through, about 8 minutes, stirring occasionally.
- Stir in the diced tomatoes and Italian seasoning. Season with salt and pepper to taste. Allow to simmer for an additional 5 minutes, allowing the flavors to meld.
- Spoon the chicken mixture into the prepared zucchini boats. Top each boat with grated mozzarella cheese.
- Arrange the stuffed zucchini in a baking dish, cover with foil, and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 5-10 minutes, or until the cheese is bubbly and golden.

FAQ
Can I make the filling ahead of time?
Yes — the chicken filling can be made up to 2 days ahead and stored in the fridge. Just reheat it briefly in the skillet before spooning it into the zucchini shells so it goes into the oven warm, which helps everything cook evenly.
Can I use ground chicken or turkey instead of diced chicken breast?
Ground chicken or turkey works well and is often cheaper. Brown it the same way you would the diced breast, breaking it up as it cooks, and drain off any excess fat before adding the tomatoes.
Do I need to pre-cook the zucchini shells before filling them?
No, the recipe bakes them from raw and the timing accounts for that. Pre-cooking the shells risks overcooking them by the time the filling is hot and the cheese is set.
My zucchini are small — can I still use them?
You can, but you’ll need more of them and will have leftover filling. Three medium zucchini can replace two large ones — just watch the bake time since thinner walls cook faster.
Is there a dairy-free option for the cheese topping?
A dairy-free shredded mozzarella alternative melts reasonably well here. You can also skip the cheese entirely and finish the boats with a drizzle of olive oil and a handful of breadcrumbs for a bit of texture on top.
Can I add other vegetables to the filling?
Diced bell pepper or mushrooms both fold in easily — add them to the skillet with the onion so they have time to soften. Avoid vegetables with very high water content like spinach unless you squeeze them dry first.
