Preparation & Cooking Time

Cook Time: 25–30 minutes
Total Time: 40–45 minutes
Servings: 4
Course: Main Course / Side Dish
Cuisine: American / Mediterranean
Ingredients
4 medium zucchini
1 cup fresh mushrooms, sliced
2 cups fresh spinach, chopped
1 cup shredded mozzarella cheese
¼ cup grated Parmesan cheese
2 cloves garlic, minced
1 tablespoon olive oil
½ teaspoon Italian seasoning
¼ teaspoon black pepper
½ teaspoon salt, or to taste
2 tablespoons chopped fresh parsley (optional)
Instructions
Step 1: Prepare the Zucchini
Preheat your oven to 400°F (200°C). Wash the zucchini and cut each one in half lengthwise. Use a spoon to gently scoop out the center flesh, leaving a small border around the edges to create little boats. Chop the scooped zucchini flesh and set aside.
Step 2: Prepare the Filling
Heat olive oil in a skillet over medium heat. Add the minced garlic and sliced mushrooms. Cook for 4–5 minutes until the mushrooms soften and release their moisture.
Step 3: Add Spinach
Add the chopped spinach and reserved zucchini flesh to the skillet. Cook for another 2–3 minutes until the spinach wilts and excess moisture evaporates.
Step 4: Season the Mixture
Stir in Italian seasoning, salt, and black pepper. Remove the skillet from the heat and allow the mixture to cool slightly.
Step 5: Add the Cheese
Mix in half of the mozzarella and all the Parmesan cheese. Stir until everything is evenly combined.
Step 6: Stuff the Zucchini Boats
Arrange the zucchini halves in a lightly greased baking dish. Spoon the mushroom and spinach mixture evenly into each zucchini boat. Top with the remaining mozzarella cheese.
Step 7: Bake Until Golden
Bake uncovered for 20–25 minutes, or until the zucchini is tender and the cheese is melted, bubbly, and lightly golden. For extra browning, broil for 1–2 minutes at the end, watching carefully.
Step 8: Garnish and Serve
Remove from the oven and let rest for 3–5 minutes. Sprinkle with fresh parsley and serve warm.
Helpful Tips for Perfect Zucchini Boats
Choose medium-sized zucchini for the best balance of filling and vegetable.
Avoid overcooking the zucchini so the boats hold their shape.
Cook the mushrooms thoroughly to remove excess moisture.
Drain any extra liquid from the spinach mixture before stuffing.
Use freshly shredded mozzarella for a creamier, better-melting topping.
Add red pepper flakes if you enjoy a little heat.
