    Instructions
  1. Prepare the Oven

Preheat your oven to 400°F (200°C). Lightly grease a baking dish with olive oil or cooking spray.

  1. Prepare the Zucchini

Wash the zucchini and trim off the ends. Slice each zucchini lengthwise into two halves.

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

Finely chop the scooped-out zucchini flesh and set aside.

  1. Pre-Bake the Zucchini

Arrange the zucchini halves in the prepared baking dish. Brush lightly with olive oil and season with salt and black pepper.

Bake for 8–10 minutes to soften slightly. Remove from the oven and carefully drain any excess liquid.

  1. Cook the Mushrooms

Heat olive oil and butter in a large skillet over medium heat.

Add the chopped mushrooms and cook for 5–7 minutes until their moisture evaporates and they begin to turn golden.

Add the diced onion and chopped zucchini flesh. Cook for another 3–4 minutes until softened.

  1. Add Garlic and Spinach

Stir in the minced garlic and cook for about 30 seconds until fragrant.

Add the fresh spinach and cook until wilted, approximately 2 minutes.

Remove the skillet from the heat and allow the mixture to cool slightly. Drain any excess moisture if necessary.

  1. Prepare the Creamy Ricotta Filling

In a large mixing bowl, combine ricotta cheese, ½ cup mozzarella, Parmesan, egg, Italian seasoning, paprika, black pepper, and parsley.

Add the cooked mushroom and spinach mixture. Stir until everything is evenly combined.

Taste and adjust the seasoning as needed.

  1. Stuff the Zucchini Boats

Spoon the ricotta, mushroom, and spinach mixture generously into each zucchini half.

Arrange the stuffed zucchini boats in the baking dish.

  1. Add the Cheese Topping

Sprinkle the remaining mozzarella and Parmesan evenly over the stuffed zucchini boats.

  1. Bake Until Golden

Bake uncovered for 18–22 minutes, until the zucchini is tender, the filling is heated through, and the cheese is melted.

For a beautifully golden top, broil for 1–2 minutes at the end, watching carefully to prevent burning.

  1. Garnish and Serve

Remove from the oven and let rest for 5 minutes. Sprinkle with fresh parsley and red pepper flakes if desired.

Serve warm and enjoy!

Helpful Cooking Tips

  • Choose medium zucchini: They are easier to scoop and hold their shape during baking.
  • Remove excess moisture: Mushrooms, spinach, and zucchini all release water. Cook the filling until excess liquid evaporates.
  • Don’t scoop too deeply: Leave enough zucchini around the edges to keep the boats sturdy.
  • Use whole-milk ricotta: It creates a richer and creamier filling.
  • Avoid overbaking: Zucchini should be tender but still hold its shape.
  • Make the tops golden: A short broil at the end gives the cheese a beautiful finish.
  • Add extra flavor: Sun-dried tomatoes, fresh basil, or a little lemon zest make delicious additions.

  • Freezing: Freeze fully cooked and cooled zucchini boats in a freezer-safe container for up to 2 months. The zucchini may become softer after thawing.
  • Make ahead: Prepare the filling up to one day ahead and refrigerate separately. Stuff and bake the zucchini when ready to serve.
    Frequently Asked Questions (Q&A)
    Q1: Can I make stuffed zucchini boats ahead of time?

Yes! Prepare the filling and scoop out the zucchini a day ahead. Store them separately in the refrigerator, then assemble and bake when ready.
