These stuffed zucchini boats are halved zucchinis filled with a quinoa mixture of cherry tomatoes, Kalamata olives, red onion, garlic, parsley, and mint, then baked and finished with a tahini drizzle. The filling comes together while the zucchinis roast, so the whole thing lands on the table in about 40 minutes. It’s a solid weeknight dinner that also holds up well enough to serve to guests.
What makes this version work
Two things actually move the needle here. First, sautéing the scooped-out zucchini flesh before it goes back into the filling drives off excess moisture — skip this step and the stuffing turns soggy by the time it reaches the table. Second, pre-cooking the quinoa until it’s just done (not mushy) matters more than it sounds: the quinoa finishes cooking inside the boat, so starting with overcooked grains gives you a gluey filling. Pull the quinoa off the heat while it still has a little bite. Everything else in this recipe is forgiving; those two steps are not.
Troubleshooting
- Zucchini shells collapse in the pan: They were hollowed out too thin. Leave at least a ¼-inch wall when scooping. If they’ve already collapsed, nestle them tightly together in the baking dish — they’ll hold each other upright.
- Filling tastes flat: Kalamata olives and lemon juice are doing most of the seasoning work here. Taste the filling before it goes into the boats and add another squeeze of lemon or a few more chopped olives before adjusting salt.
- Tahini sauce seizes up into a thick paste: Add warm water one teaspoon at a time and whisk between each addition. Cold water makes it seize faster, so use warm.
- Boats are done on top but the zucchini shell is still firm and raw-tasting: Your oven runs cool or the zucchinis were very large. Cover the dish loosely with foil and give them 5 to 8 more minutes — skip the garnish at this point, not worth the extra dish when you just want dinner ready.
- Filling spills out during baking: Mound it slightly above the rim of the boat; it will settle and compact as it bakes. If you overfilled, press the mixture down gently with a spoon before the dish goes in the oven.
Mediterranean Stuffed Zucchini Boats
Equipment
- Sharp knife
- Spoon or melon baller
- Large skillet
- Baking dish
- Mixing bowl
Ingredients
Main Ingredients
- 4 medium zucchinis look for firm, evenly sized zucchinis approximately 6 inches long
- 1 tablespoon extra virgin olive oil for sautéing
- 1 cup cooked quinoa cooled; tri-color quinoa adds visual appeal
- 1 cup cherry tomatoes halved; use heirloom for more color
- ⅓ cup Kalamata olives pitted and chopped
- ¼ cup red onion finely diced
- 2 cloves garlic minced
- 2 tablespoons fresh parsley finely chopped
- 1 tablespoon fresh mint chopped
- 1 teaspoon lemon zest
- 2 tablespoons lemon juice freshly squeezed
- ¼ teaspoon sea salt or to taste
- ⅛ teaspoon black pepper freshly ground
Tahini Drizzle (Optional)
- ¼ cup tahini creamy texture works best
- 2 tablespoons lemon juice
- 2 tablespoons warm water adjust to preferred drizzle consistency
- 1 pinch salt
Instructions
- Preheat your oven to 375°F (190°C). Prepare a baking dish by lightly greasing the base with olive oil or lining with parchment paper.
- Wash the zucchinis and slice each one in half lengthwise. Using a spoon or melon baller, carefully scoop out the inner flesh to create a 'boat,' leaving about 1/4 inch of zucchini around the edges for support. Reserve the scooped flesh and finely chop it.
- In a skillet over medium heat, warm the olive oil. Sauté the red onion for 2–3 minutes until it begins to soften. Add garlic and reserved chopped zucchini flesh. Cook for 3–5 minutes until fragrant and lightly golden.
- Transfer the sautéed mixture to a bowl. Add cooked quinoa, cherry tomatoes, olives, parsley, mint, lemon zest, lemon juice, salt, and pepper. Mix thoroughly until all ingredients are well incorporated.
- Stuff each zucchini half generously with the quinoa filling, pressing slightly to mound it. Place them snugly in the prepared baking dish.
- Bake uncovered for 25–30 minutes until zucchinis are tender and the tops are lightly crisp.
- While the boats are baking, whisk together tahini, lemon juice, warm water, and salt until smooth. Drizzle over warm zucchini boats before serving or serve on the side.
Notes
- Substitution Tip: Replace quinoa with couscous or cooked lentils for a protein variation.
- Flavor Booster: Add a pinch of cumin or smoked paprika to the sauté for a deeper aroma.
- Make-Ahead: Quinoa filling can be made a day in advance and kept refrigerated.

Your questions, answered
Can I make any part of this ahead of time?
Yes — cook the quinoa filling up to 24 hours ahead and refrigerate it in an airtight container. When you’re ready to eat, hollow out the zucchinis, fill them cold straight from the fridge, and add 3 to 5 minutes to the bake time.
Can I use a different grain instead of quinoa?
Cooked brown rice or cooked lentils both work well and keep the dish gluten-free. Couscous works too but is not gluten-free; use the same volume as the cooked quinoa called for in the recipe.
My zucchinis are very large — does that change anything?
Large zucchinis have more water in the flesh, so sauté the scooped-out pulp a minute or two longer than the recipe specifies. You may also need to increase the bake time by 5 to 10 minutes to get the shell fully tender.
Is the tahini drizzle necessary, or can I skip it?
You can skip it and the dish is still complete. If you want something creamy on top but don’t have tahini, a spoonful of plain unsweetened hummus thinned with lemon juice does the same job.
