Ingredients

For the Zucchini Boats

• 4 medium zucchini
• 1 tablespoon olive oil
• 8 oz (225 g) mushrooms, finely chopped
• 2 cups fresh spinach, roughly chopped
• 2 cloves garlic, minced
• 1 cup ricotta cheese
• ½ cup grated Parmesan cheese, divided
• ¼ cup shredded mozzarella cheese
• ½ teaspoon Italian seasoning
• ¼ teaspoon red pepper flakes, optional
• ½ teaspoon salt, or to taste
• ¼ teaspoon black pepper
• 2 tablespoons fresh parsley or basil, chopped
• 2 tablespoons breadcrumbs, optional

Optional Garnish

• Fresh basil or parsley
• Extra Parmesan
• A drizzle of olive oil
• Crushed red pepper flakes

Instructions

1. Prepare the zucchini

Preheat your oven to 400°F (200°C).

Wash and dry the zucchini. Slice each zucchini in half lengthwise. Using a spoon, carefully scoop out the center flesh, leaving about ¼ inch (½ cm) of zucchini around the edges.

Finely chop the zucchini flesh and set it aside.

2. Prepare the filling

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

Add the chopped mushrooms and cook for 5–7 minutes, stirring occasionally, until their moisture evaporates and they begin to brown.

Add the chopped zucchini flesh and cook for another 2–3 minutes.

Add the garlic and spinach. Cook for 1–2 minutes, until the spinach wilts and most excess moisture has evaporated.

Remove the skillet from the heat.

3. Make the ricotta filling

Transfer the cooked vegetables to a bowl.

Stir in:

• Ricotta
• ¼ cup Parmesan
• Italian seasoning
• Red pepper flakes, if using
• Salt
• Black pepper
• Fresh herbs

Mix until well combined.

Tip: Allow the vegetables to cool slightly before adding the ricotta so the filling remains creamy rather than becoming watery.

4. Fill the zucchini

Arrange the zucchini halves cut-side up in a lightly greased baking dish.

Spoon the ricotta, mushroom, and spinach mixture evenly into each zucchini boat.

Sprinkle the remaining Parmesan and mozzarella over the tops. Add breadcrumbs if you want a slightly crispier topping.

5. Bake

Cover the baking dish loosely with foil and bake for 20 minutes.

Remove the foil and bake for another 8–12 minutes, until the zucchini is tender and the cheese is melted and lightly golden.

For a more golden top, broil for 1–2 minutes, watching carefully.

6. Rest and serve

Let the zucchini boats rest for 5 minutes before serving.

Garnish with fresh parsley or basil and additional Parmesan if desired.

Recipe Notes

• Don’t overcook the zucchini. It should be tender but still hold its shape.
• Mushrooms release a lot of water, so cook them thoroughly before adding the ricotta.
• For firmer zucchini boats, bake uncovered for most of the cooking time.
• Ricotta can vary in moisture. If yours is particularly wet, drain it briefly before using.
• The filling can be prepared up to 1 day ahead and refrigerated.
• Leftovers can be refrigerated in an airtight container for about 3 days.
• Reheat in a 350°F (175°C) oven until warmed through for the best texture.

Helpful Tips

Make it extra flavorful

Add a little lemon zest, fresh basil, or a small amount of sun-dried tomato to the filling.

Make it more filling

Serve with quinoa, brown rice, couscous, garlic bread, or a fresh salad.

Make it lower-carb

Simply leave out the breadcrumbs.

Make it gluten-free

Use certified gluten-free breadcrumbs, or omit them entirely.

Add protein

For a non-vegetarian variation, cooked shredded chicken or turkey can be mixed into the filling.

Prevent watery zucchini

Salt the zucchini lightly after scooping and let it sit for 10 minutes. Pat dry before filling. Also make sure the mushroom-spinach mixture is cooked until excess liquid has evaporated.

Serving Suggestions

These zucchini boats pair especially well with:

• Fresh green salad
• Tomato and cucumber salad

Frequently Asked Questions

Q: Can I make these zucchini boats ahead of time?
Yes. Assemble them several hours ahead, cover, and refrigerate. Bake when ready, adding a few extra minutes to the cooking time if they’re going directly from the refrigerator to the oven.

Q: Can I use frozen spinach?
Absolutely. Thaw it completely and squeeze out as much water as possible before adding it to the filling.

Q: Can I use cottage cheese instead of ricotta?
Yes. For a smoother filling, blend the cottage cheese briefly before mixing it with the vegetables.

Q: Why are my zucchini boats watery?
The most common causes are watery zucchini, mushrooms that weren’t cooked long enough, or spinach that retained excess moisture. Cook the vegetables until the excess liquid has evaporated and drain wet ingredients well.

Q: Can I freeze stuffed zucchini boats?
You can, although the zucchini may become softer after thawing. For the best texture, freeze the filling separately and prepare fresh zucchini when possible.

Q: Can I make this recipe vegan?
Yes. Replace the ricotta with a plant-based ricotta alternative and use vegan Parmesan and mozzarella-style cheese.

Q: How do I make them spicy?
Add red pepper flakes, finely chopped jalapeño, or a little chili powder to the filling.

Q: What can I use instead of mushrooms?
Try finely chopped bell peppers, broccoli, eggplant, corn, or additional spinach.

Q: Are these suitable as a main dish?
Yes. Two zucchini halves make a light vegetarian meal. For a heartier meal, serve them with quinoa, rice, lentils, or a bean salad.

Q: How should I store leftovers?
Place cooled zucchini boats in an airtight container and refrigerate for up to about 3 days. Reheat in the oven or air fryer for better texture than microwaving.
