Spinach, Mushroom, and Ricotta Stuffed Zucchini Boats
There are days when I want something cozy and cheesy, but I also want dinner to feel fresh and full of vegetables.
That’s exactly where these Spinach, Mushroom, and Ricotta Stuffed Zucchini Boats come in.
Tender zucchini is hollowed out and filled with a creamy mixture of ricotta, sautéed mushrooms, spinach, garlic, herbs, and Parmesan. Everything gets baked until the zucchini is tender and the cheese on top is beautifully golden.
I first made these on a weekend when I had a few extra zucchini sitting in the refrigerator and didn’t want them to go to waste.
I started thinking about what I could stuff them with.
There was some ricotta in the fridge, mushrooms that needed to be used, and a bag of fresh spinach. It seemed like the perfect combination.
Once the mushrooms and garlic started cooking, the kitchen smelled so good that I knew I was onto something.
I mixed everything with creamy ricotta, filled the zucchini boats, sprinkled Parmesan and mozzarella over the top, and baked them until bubbly.
My family loved them.
Even the people who usually ask, “Where’s the meat?” were reaching for another zucchini boat.
Since then, I’ve made these whenever I want a comforting vegetable-centered dinner that doesn’t feel boring or bland.

Ingredients
For the Zucchini
- 4 medium zucchini
- 1 tablespoon olive oil
- ½ teaspoon salt
- ¼ teaspoon black pepper
For the Filling
- 1 tablespoon olive oil
- 225 g mushrooms, finely chopped
- 3 cloves garlic, minced
- 3 cups fresh baby spinach
- 1 cup ricotta cheese
- ½ cup grated Parmesan cheese
- ½ teaspoon Italian seasoning
- ¼ teaspoon red pepper flakes, optional
- ¼ teaspoon black pepper
- ½ teaspoon salt, or to taste
- 1 egg
- 2 tablespoons fresh parsley, chopped
For the Topping
- ½ cup shredded mozzarella
- 2 tablespoons grated Parmesan
- 1 tablespoon fresh parsley
Instructions
Step 1: Prepare the Zucchini
Preheat the oven to 200°C (400°F).
Wash the zucchini and slice each one in half lengthwise.
Using a spoon, carefully scoop out the center, leaving about ¼ inch of zucchini around the edges so the boats remain sturdy.
Don’t throw away the zucchini flesh.
Chop it finely and reserve it for the filling.
Place the zucchini halves cut-side up in a lightly oiled baking dish.
Brush them with olive oil and season with salt and black pepper.
Step 2: Pre-Bake the Zucchini
Bake the zucchini boats for approximately 8–10 minutes.
This gives them a head start so the finished boats are tender without becoming overly soft.
Remove them from the oven.
Step 3: Cook the Mushrooms
While the zucchini is pre-baking, heat olive oil in a large skillet over medium heat.
Add the chopped mushrooms.
Cook for approximately 5–7 minutes, stirring occasionally, until the mushrooms release their moisture and begin to brown.
Step 4: Add the Garlic and Spinach
Add the minced garlic and cook for about 30 seconds.
Add the fresh spinach and chopped zucchini flesh.
Cook for another 2–3 minutes, stirring until the spinach wilts and most of the excess moisture has cooked away.
Remove from the heat and let the mixture cool slightly.
Step 5: Make the Ricotta Filling
In a large bowl, combine:
- Ricotta
- Parmesan
- Egg
- Italian seasoning
- Salt
- Black pepper
- Red pepper flakes
- Fresh parsley
Add the cooked mushroom and spinach mixture.
Stir everything together until well combined.
Step 6: Fill the Zucchini Boats
Spoon the ricotta mixture generously into each zucchini half.
Don’t worry if the filling sits slightly above the edges—it will settle as it cooks.
Step 7: Add the Cheese
Sprinkle shredded mozzarella and a little extra Parmesan over each zucchini boat.
Step 8: Bake
Return the baking dish to the oven.
Bake for approximately 20–25 minutes, or until the zucchini is tender and the cheese is melted and golden.
For a more deeply browned top, switch to the broiler for the final 1–2 minutes.
Watch carefully so the cheese doesn’t burn.
Step 9: Garnish and Serve
Let the zucchini boats rest for a few minutes.
Sprinkle with fresh parsley and serve warm.
My Best Tips
Don’t Scoop Out Too Much
Leave enough zucchini around the edges to keep the boats sturdy.
Cook the Mushrooms Well
Mushrooms contain a lot of moisture. Cooking them until their water evaporates prevents the filling from becoming watery.
Don’t Skip the Pre-Bake
A short pre-bake helps the zucchini become tender while keeping the filling creamy and the cheese nicely browned.
Drain Excess Liquid
If your cooked spinach and mushrooms look particularly wet, let them cook for another minute or two before mixing them with the ricotta.
Delicious Variations
Spinach and Feta Zucchini Boats
Replace half of the ricotta with crumbled feta for a stronger Mediterranean flavor.
Chicken Stuffed Zucchini Boats
Add 1 cup of finely chopped cooked chicken to the filling.
Italian-Style Zucchini Boats
Add marinara sauce, mozzarella, basil, and Italian sausage.
Spicy Mushroom Zucchini Boats
Add extra red pepper flakes, chili flakes, or diced jalapeño.
Tomato and Ricotta Zucchini Boats
Add chopped sun-dried tomatoes or halved cherry tomatoes to the filling.
Low-Carb Zucchini Boats
The basic recipe is already relatively low in carbohydrates and makes a satisfying vegetable-centered meal.
What to Serve With Zucchini Boats
These can be served as a main dish or side.
For a complete meal, try them with:
- Mediterranean salad
- Tomato and cucumber salad
- Grilled chicken
- Baked salmon
- Garlic shrimp
- Roasted potatoes
- Quinoa
- Crusty whole-grain bread
I especially love serving them with a simple tomato salad dressed with olive oil and lemon.
Make-Ahead Instructions
You can prepare the zucchini and filling several hours ahead.
Keep the filling refrigerated until you’re ready to assemble and bake.
You can also assemble the entire dish, cover it, and refrigerate it for several hours.
Add a few extra minutes to the baking time if the zucchini goes directly from the refrigerator into the oven.
Storage Instructions
Store leftover zucchini boats in an airtight container in the refrigerator for up to 3 days.
Reheat them in the oven or air fryer until warmed through.
The microwave works too, although the cheese topping won’t be as crisp.
Freezing
Because zucchini contains a lot of water, freezing can change its texture and make it softer.
For the best results, I recommend enjoying these fresh or storing them in the refrigerator rather than freezing them.

Frequently Asked Questions
Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much water as possible before adding it to the filling.
Can I use cottage cheese instead of ricotta?
Yes. Cottage cheese can work well, although the filling will have a slightly different texture. For a smoother filling, blend the cottage cheese briefly before using it.
Can I make these without mushrooms?
Absolutely. Add extra spinach, chopped bell peppers, zucchini, or sun-dried tomatoes instead.
Can I prepare them ahead of time?
Yes. Assemble the boats several hours ahead and refrigerate them until you’re ready to bake.
Are these vegetarian?
Yes. The recipe is vegetarian as written.
Can I make them dairy-free?
You can use dairy-free ricotta and dairy-free mozzarella and Parmesan alternatives.
How do I stop zucchini boats from becoming watery?
The key is cooking the mushrooms, spinach, and zucchini flesh thoroughly before mixing them with the ricotta. Removing excess moisture makes a big difference.
