wafaawjjamal

• Prep time: 15 minutes
• Cook time: 30 minutes
• Total time: 45 minutes

• Serves: 4

Ingredients

For the zucchini boats:

• 4 medium zucchini, halved lengthwise
• 1 tablespoon extra virgin olive oil
• 1/4 teaspoon salt
• 1/4 teaspoon black pepper

For the lemon ricotta filling:

• 1 1/2 cups whole milk ricotta
• 1/2 cup freshly grated Parmesan or Parmigiano Reggiano
• 1/2 cup shredded mozzarella
• 2 cloves garlic, finely grated or minced
• Zest of 1 lemon
• 1 tablespoon fresh lemon juice
• 3 tablespoons fresh parsley, chopped
• 1 tablespoon fresh basil, chopped
• 1 egg
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 teaspoon red pepper flakes, optional

For finishing:

• Extra Parmesan for topping
• Fresh parsley or basil
• Lemon wedges
• A drizzle of extra virgin olive oil

Instructions

• 1)

  Make sure to carefully follow each step of the instructions for the best results :

  • Preheat the oven and prep the zucchini.
    Preheat the oven to 400°F and line a large baking dish or sheet pan with parchment paper. Halve the zucchini lengthwise and use a spoon or melon baller to carefully scoop out the flesh, leaving about a 1/4-inch border all around to create a sturdy boat. Reserve the scooped flesh for the filling. Most lemon ricotta stuffed zucchini recipes begin with par-cooking or directly filling and baking the prepared boats, with the hollow creating the perfect cavity for the creamy ricotta mixture.
  • Prepare the zucchini flesh.
    Finely chop the reserved zucchini flesh and place it in a clean kitchen towel or several layers of paper towels. Squeeze firmly to remove as much moisture as possible. This step is important because excess water from the zucchini pulp can make the filling watery and prevent it from setting properly in the oven.
  • Make the lemon ricotta filling.
    In a large bowl, combine the ricotta, Parmesan, mozzarella, garlic, lemon zest, lemon juice, parsley, basil, egg, salt, pepper, and red pepper flakes if using. Stir in the squeezed zucchini flesh until everything is evenly combined. The egg helps bind the filling so it holds together neatly when baked, while the lemon zest and fresh herbs keep the flavor light and vibrant.
  • Fill and season the boats.
    Arrange the zucchini boats cut-side up in the prepared baking dish. Drizzle them lightly with olive oil and season with salt and pepper. Spoon the ricotta filling generously into each boat and smooth the tops slightly. Finish with a sprinkle of extra Parmesan over each one.
  • Bake until golden.
    Bake for 20 to 25 minutes until the zucchini is tender and the filling is set and lightly golden on top. For a more browned, bubbly top, switch the oven to broil for the final 3 to 5 minutes and watch closely. Broiling the filled boats briefly at the end gives the cheese a beautiful golden finish.
  • Rest and serve.
    Let the boats cool for 3 to 5 minutes before serving. Scatter fresh parsley or basil over the top, add a drizzle of extra virgin olive oil, and serve with lemon wedges on the side.

Tips for the Best Lemon Ricotta Stuffed Zucchini Boats

• Squeeze the zucchini flesh very well before adding it to the filling to prevent a watery result
• Use whole milk ricotta for the richest, creamiest texture
• Freshly grated Parmesan melts better and gives a cleaner flavor than pre-shredded
• Don’t hollow out the zucchini too deeply or the walls will collapse during baking
• The lemon zest carries far more brightness than lemon juice alone, so don’t skip it
• Broiling at the end gives the most appealing golden finish
• Serve immediately for the best texture, while the cheese is warm and creamy inside

Variations

• Sun-dried tomato version. Stir chopped sun-dried tomatoes into the ricotta filling for a sweet, savory contrast
• Goat cheese version. Replace half the ricotta with soft goat cheese for a tangier, more complex filling
• Meat version. Mix cooked ground turkey or Italian sausage into the filling for a heartier, protein-rich boat
• Spinach version. Add a handful of wilted, squeezed spinach to the filling for extra color and nutrition
• Pizza version. Top with marinara and mozzarella for a fun, low carb pizza-style boat

Can I Add Protein to These Zucchini Boats?

Yes, and it works very well. Cooked ground turkey, Italian sausage, or shredded chicken can all be stirred directly into the lemon ricotta filling to make this a more protein-rich main course. The ricotta still provides a creamy, cheesy base and the lemon and herb flavors carry through beautifully even with meat added.

What to Serve with Lemon Ricotta Stuffed Zucchini Boats

These light boats pair beautifully with simple sides:

• A crisp green salad with lemon vinaigrette
• Roasted asparagus or green beans
• Sliced tomatoes with basil and olive oil
• Cauliflower soup
• Garlic sautéed spinach
• Warm focaccia or crusty bread for a less strict option

Storage & Reheating

Store leftover zucchini boats in an airtight container in the refrigerator for up to 3 days. They reheat well in a 350°F oven for about 10 minutes until warmed through and the cheese is soft again.

They can also be made ahead and refrigerated unbaked, then put directly into the oven when ready to serve. This makes them a practical option for light weeknight dinners or casual entertaining.

FAQ

Can I make these ahead of time?

Yes. Fill the boats and refrigerate unbaked for up to 24 hours, then bake just before serving for the freshest result.

Do I have to use the scooped zucchini flesh?

No, but adding it back into the filling reduces waste and adds texture. Just make sure to squeeze it very dry first.

Can I use part-skim ricotta instead of whole milk?

Yes, though whole milk ricotta gives a creamier, richer result. Part-skim will still work well.

Is this recipe gluten-free?

Yes, it is naturally gluten-free as written when made without breadcrumbs.

Can I freeze these?

Zucchini boats can be frozen after baking, though the texture of the zucchini will soften after thawing. They are best enjoyed fresh or from the refrigerator within 3 days.
