Zucchini boats with quinoa

Tender roasted zucchini halves are filled with a savory quinoa mixture of tomatoes, peppers, onion, garlic, and feta, then baked until the tops are lightly browned. This makes 2 hearty servings, with the zucchini soft enough to scoop but still structured, and the filling fluffy rather than mushy.

This recipe scales well to 4 servings by doubling all ingredients and using two sheet pans or a larger roasting pan so the zucchini halves sit in a single layer. Keep the oven at 425 F, but add a few minutes only if the pan is crowded. For 6 or more servings, bake in batches so the boats roast instead of steaming.

Step 1

Heat the oven and start the quinoa

~15 min cook

Heat the oven and start the quinoa.

Set the oven to 425 F.

Line a rimmed baking sheet or a 9x13-inch baking dish with foil or parchment for easier cleanup.

In a small saucepan, combine 1/2 cup dry quinoa and 1 cup water.

Bring to a boil over medium-high heat, then reduce to low, cover, and cook for 15 minutes until the water is absorbed

Ingredients
  • 1/2 cupDry quinoa
  • 1 cupWater
Step 2

Remove from the heat and keep covered

After ~15 min

Remove from the heat and keep covered for 5 minutes so the grains finish steaming.

Step 3

Prepare the zucchini boats

~1 min

Prepare the zucchini boats.

While the quinoa cooks, halve 2 medium zucchini lengthwise.

Use a spoon to scoop out a shallow trough from the center of each half, leaving about 1/4 inch of zucchini around the edges so the shells hold their shape.

Chop 1/2 cup of the scooped zucchini flesh finely and reserve it for the filling.

Arrange the zucchini cut-side up on the prepared pan and brush the cut surfaces with about 1/2 tablespoon of the olive oil.

Ingredients
  • 2Medium zucchini, 14 oz total, halved lengthwise and lightly scooped
  • 1/2 tablespoonOlive oil
  • 1/2 cup total for recipeDry quinoa
Step 4

Par-roast the zucchini shells

~10 min cook

Par-roast the zucchini shells.

Season the zucchini shells with 1/4 teaspoon of the kosher salt and roast for 10 minutes.

This head start keeps the finished boats from becoming watery and gives the edges a little browning before the filling goes in.

Ingredients
  • 1/4 teaspoonKosher salt
Step 5

Check zucchini

After ~10 min

Check Zucchini boats with quinoa and continue when ready.

Step 6

Build the filling

~7 min

Build the filling.

Heat the remaining 1/2 tablespoon olive oil in a medium skillet over medium heat.

Add 1/2 cup diced onion and 1/2 cup diced red bell pepper and cook for 4 to 5 minutes, stirring often, until the onion turns translucent and the pepper softens.

Add the reserved chopped zucchini, 2 tbsp tomato paste, 2 tsp minced garlic, 1 tsp dried oregano, 1/4 teaspoon black pepper, and the remaining 1/4 teaspoon kosher salt.

Cook for 2 minutes, stirring and pressing the tomato paste into the vegetables so it darkens slightly and loses its raw taste.

  • 1 tspDried oregano
Step 7

Finish the quinoa mixture

~2 min

Finish the quinoa mixture.

Stir in 1 cup quartered cherry tomatoes and the cooked quinoa.

Cook for 1 to 2 minutes more, just until everything is evenly combined and the tomatoes begin to slump.

Take the skillet off the heat and fold in 2 oz crumbled feta, 1 tbsp lemon juice, and 1 tbsp chopped parsley.

The filling should look moist but not soupy; if it seems dry, add 1 to 2 tablespoons of water so it mounds easily in the zucchini.

Ingredients
  • 1/2 cup total for recipeDry quinoa
  • 1 cup total for recipeCherry tomatoes, quartered
  • 1 tbspLemon juice
  • 1 tbspParsley
Step 8

Fill and bake

~15 min cook

Fill and bake.

Remove the zucchini shells from the oven and divide the quinoa filling among them, packing it gently into the cavities and mounding it slightly on top.

Return the pan to the oven and bake for 12 to 15 minutes, until the zucchini is tender when pierced with a knife and the tops are hot with a few browned spots.

If you want more color, broil for 1 minute at the end, watching closely.

Step 9

Check zucchini

After ~15 min

Check Zucchini boats with quinoa and continue when ready.

Step 10

Rest and serve

~5 min cook

Rest

Let the boats rest for 5 minutes before serving so the filling settles and the zucchini finishes softening from residual heat

Before you cook

What to get ready

The recipe's baking dish, saucepan or skillet for the filling, oven mitts and thermometer.

Leave enough zucchini flesh to support the shells and cook quinoa before filling.

If something needs adjusting

Boats collapse around the filling

Avoid scooping too deeply or overbaking the shells; fill them without packing tightly.

A larger batch heats unevenly

Use a second shallow dish rather than making a much deeper casserole. Check the center, not only the bubbling edges, before serving.

Store for later

Portion the cooked casserole into shallow containers for prompt chilling. Reheat the center to 165°F, covering if the topping browns too soon.

Refrigerate perishables within 2 hours, or 1 hour above 90°F. Keep the fridge at 40°F or below; use refrigerated leftovers within 3–4 days. USDA storage and reheating guidance.

Make the ingredients go further

Chop usable scooped zucchini into the filling instead of throwing it away.

Tips, swaps and questions

A little kitchen know-how

For the best texture, scoop the zucchini lightly and roast the shells before filling. If you hollow them too deeply, they can collapse; if you skip the par-roast, the finished boats often release more water. Crumble the feta at the end so it stays distinct instead of melting into the quinoa.

Make it work for you

You can swap feta for 2 oz grated mozzarella if you want a milder, stretchier finish, but the filling will be less salty and less tangy, so keep the lemon juice. If you use cooked brown rice instead of quinoa, the mixture will be heavier and may need a little less moisture in the skillet.

Use more of your cherry tomatoes and yellow onion in baked cod with tomatoes.

Can I make the quinoa filling ahead of time?

Yes. Cook the quinoa and make the vegetable filling up to 3 days ahead, then refrigerate them separately in sealed containers. Assemble and bake the zucchini right before serving so the shells stay firm and do not shed excess liquid. Reheat leftovers to 165 F.
