Instructions

Step 1: Prepare the Zucchini

Preheat the oven to 375°F (190°C).

Slice each zucchini in half lengthwise.

Using a spoon, scoop out the center flesh, leaving about ¼ inch around the edges to create sturdy boats.

Finely chop the scooped zucchini flesh and set aside.

Brush the zucchini boats with olive oil and season with salt and pepper.

Arrange them in a lightly greased baking dish.

Step 2: Cook the Filling

Heat the olive oil in a large skillet over medium heat.

Add the onion and cook for 3–4 minutes until softened.

Stir in the garlic and cook for 30 seconds.

Add:

• Chopped mushrooms
• Reserved zucchini flesh

Cook for 5–6 minutes, allowing most of the moisture to evaporate.

Add the spinach and cook until wilted, about 2 minutes.

Remove from the heat and allow the mixture to cool for 5 minutes.

Step 3: Make the Ricotta Mixture

In a mixing bowl, combine:

• Ricotta cheese
• Mozzarella cheese
• Parmesan cheese
• Egg
• Italian seasoning
• Oregano
• Paprika
• Salt
• Black pepper

Fold in the cooled mushroom and spinach mixture until evenly combined.

Step 4: Fill the Zucchini

Spoon the ricotta mixture generously into each zucchini boat.

Top with:

• Mozzarella cheese
• Parmesan cheese
• Panko breadcrumbs (optional)

Drizzle lightly with olive oil.

Step 5: Bake

Bake uncovered for 30–35 minutes, or until:

• The zucchini is tender.
• The filling is hot and set.
• The cheese is melted and lightly golden.

For a crispier top, broil for 2 minutes at the end of baking.

Step 6: Garnish and Serve

Let the zucchini boats rest for 5 minutes.

Garnish with:

• Fresh basil
• Chopped parsley
• Extra Parmesan
• Lemon wedges, if desired

Serve warm.

Tips for Perfect Stuffed Zucchini Boats

Choose Medium-Sized Zucchini

Medium zucchini cook evenly and hold the filling well without becoming watery.

Remove Excess Moisture

Cook the mushrooms thoroughly and allow excess liquid to evaporate before mixing with the cheese.

Don’t Over-Scoop

Leave a sturdy border of zucchini to prevent the boats from collapsing during baking.

Let the Filling Cool

Cooling the vegetable mixture slightly before adding the egg prevents it from scrambling.

Serving Suggestion

Chef’s Secret

After scooping out the zucchini, lightly sprinkle the boats with a pinch of salt and let them sit for 10 minutes. Pat them dry with paper towels before filling. This helps draw out excess moisture, resulting in firmer zucchini and a creamier, more concentrated filling. Finish with a drizzle of high-quality extra virgin olive oil and fresh basil for restaurant-quality flavor. 😋🥒🍄🧀✨

Yes! Yellow summer squash works just as well and has a similar cooking time and texture.

What mushrooms are best?

Cremini (baby bella), white button, or finely chopped portobello mushrooms all provide excellent flavor.

Can I add extra vegetables?

Absolutely! Bell peppers, chopped kale, artichoke hearts, roasted red peppers, or finely diced eggplant are delicious additions.

Can I make these in the air fryer?

Yes! Air fry at 360°F (182°C) for 12–15 minutes, or until the zucchini is tender and the cheese is golden.

Is this recipe suitable for meal prep?
