Gathering Your Ingredients for Cheesy Stuffed Zucchini Boats

Making these delicious zucchini boats requires a handful of simple ingredients, many of which you might already have on hand. The magic comes from combining fresh, seasonal produce with rich, savory components.

For the base, you’ll need a couple of large zucchini. Look for ones that are firm and heavy for their size. Smaller to medium zucchini tend to be more tender and have fewer seeds, which is ideal for scooping out the cavity. You’ll also need some olive oil to sauté your aromatics.

The flavor builders start with half a small onion, finely diced. Onion provides a sweet, savory base when softened. Two cloves of garlic, minced, add that essential punch of flavor that pairs so well with both spinach and zucchini. Don’t forget to set aside about 1/4 cup of the finely chopped zucchini flesh you scoop out – we’ll add this back into the filling for extra vegetable goodness and to minimize waste.

The heart of our filling is 5 ounces of fresh spinach. Fresh spinach wilts down significantly, so 5 ounces might look like a lot at first, but it’s the perfect amount for four zucchini halves. This adds nutrition and a lovely earthy counterpoint to the richness of the cheese.

Now, let’s talk cheese! We use a dynamic duo here. 1 cup of shredded cheese blend is perfect for that melty, gooey texture. A blend of mozzarella and cheddar, or an Italian blend, works wonderfully. 2 tablespoons of grated Parmesan cheese adds a sharp, salty depth of flavor that complements the other cheeses and vegetables.

For an extra layer of creaminess (and if you happen to have it on hand!), 1/2 cup of ricotta cheese is an optional but highly recommended addition. It makes the filling even smoother and more decadent, though the boats are still delicious without it.

Seasoning is simple but crucial: 1/4 teaspoon of salt (plus extra for the salting trick!) and 1/8 teaspoon of black pepper enhance all the flavors. Remember, you can always add a little more salt and pepper to taste after mixing the filling.

Finally, we top these beauties with a buttery breadcrumb crust for texture. You’ll need 2 tablespoons of plain breadcrumbs and 1 tablespoon of melted butter.

And for a fresh finish, some fresh parsley or chives, chopped, are a lovely optional garnish, adding a pop of color and brightness.

Complete Ingredient List:

• 2 large zucchini
• 1 tablespoon olive oil
• 1/2 small onion, finely diced
• 2 cloves garlic, minced
• 5 ounces fresh spinach
• 1/4 cup finely chopped zucchini flesh (from scooping)
• 1/2 cup ricotta cheese (optional)
• 1 cup shredded cheese blend (like mozzarella, cheddar, or Italian)
• 2 tablespoons grated Parmesan cheese
• 1/4 teaspoon salt, plus more for salting zucchini
• 1/8 teaspoon black pepper
• 2 tablespoons plain breadcrumbs
• 1 tablespoon butter, melted
• Fresh parsley or chives, chopped (optional, for garnish)

Crafting Your Cheesy Stuffed Zucchini Boats: Step-by-Step

Ready to turn these simple ingredients into something spectacular? Follow these steps, paying special attention to the key moisture-removing techniques, and you’ll have perfect zucchini boats every time.

1. Let’s get the oven ready first. Preheat your oven to a cozy 375 degrees F (190 degrees C). This ensures the oven is hot and ready to bake the zucchini and melt that cheese as soon as your boats are assembled.
2. Prepare your zucchini. Give them a good wash under cool water. Trim off both ends, then carefully cut each zucchini in half lengthwise. You’ll end up with four long boat shapes.
3. Time to make the “boats”! Using a spoon, gently scoop out the seeds and some of the inner flesh from the center of each zucchini half. You want to leave a sturdy wall, about 1/4 inch thick, creating a nice cavity for your filling. Be careful not to go too thin, or the boats might collapse while baking. Take about 1/4 cup of the flesh you scooped out and finely chop it – we’ll use this later!
4. Here is the critical step to banish sogginess! Take a generous amount of salt and sprinkle it liberally over the inside cavities of all four zucchini boats. Don’t be shy! The salt is going to work hard to draw out excess water. Once salted, place the zucchini halves cut-side down on a paper towel-lined baking sheet or cutting board. Let them sit and “sweat” for at least 15 to 20 minutes. You’ll literally see droplets or even small puddles of water appearing on the paper towels – this is exactly what you want! It means the salt is doing its job and pulling out the moisture that would otherwise make your boats soggy.
5. While the zucchini is doing its thing, let’s make the delicious filling. Heat that tablespoon of olive oil in a skillet over medium heat. Add the finely diced onion and cook, stirring occasionally, until the onion softens and becomes translucent, which usually takes about 3-4 minutes. Next, add the minced garlic and the reserved, finely chopped zucchini flesh. Cook for another 2-3 minutes, stirring frequently, until the garlic is fragrant and the zucchini flesh is slightly tender.
6. Add the fresh spinach to the skillet. It will look like a mountain! Cook and stir continuously. The spinach will quickly wilt down into the pan. Continue stirring until it’s completely wilted.
7. Now, squeeze out any remaining excess liquid from the spinach mixture. Spinach holds a surprising amount of water, even after wilting. You can press the mixture against the side of the pan with the back of a spoon, or for best results, transfer it to a fine-mesh sieve and press firmly. Getting rid of this extra liquid prevents a watery filling.
8. In a medium bowl, combine your cooked and squeezed spinach mixture with the ricotta cheese (if you’re using it), the shredded cheese blend, and the grated Parmesan cheese. Add the 1/4 teaspoon of salt and the 1/8 teaspoon of black pepper. Stir everything together until the cheeses are evenly distributed and the mixture is well combined. Give it a little taste and adjust seasoning if needed.
9. Crucial follow-up! Go back to your zucchini boats. They should have released a good amount of water. Flip them over. See the salt and maybe some lingering moisture? Use fresh paper towels to thoroughly pat the inside cavities dry. This removes the drawn-out moisture AND most of the excess salt. You want the insides to be as dry as possible before adding the filling.
10. Arrange the dried zucchini boats in a baking dish. Choose one that’s just large enough to hold them somewhat snugly, so they don’t tip over while baking.
11. Divide the cheesy spinach filling evenly among the four zucchini boats. Spoon the filling generously into each cavity, mounding it slightly if needed.
12. In a small separate bowl, mix the plain breadcrumbs with the melted butter until the breadcrumbs are coated. This creates a lovely, golden, slightly crispy topping.
13. Sprinkle this buttery breadcrumb mixture evenly over the tops of the filled zucchini boats. This adds a nice textural contrast to the tender zucchini and creamy filling.
14. Pop the baking dish into your preheated oven. Bake for 20-25 minutes. You’ll know they’re done when the zucchini is tender when you pierce it with a fork (test the thickest part of the boat) and the cheesy topping is golden brown and bubbly. The exact time might vary slightly depending on the size of your zucchini and your oven.
15. Let the zucchini boats cool slightly for a few minutes before serving. The filling will be very hot! If you like, garnish with some fresh chopped parsley or chives for a burst of freshness and color.

Tips for Perfect Cheesy Stuffed Zucchini Boats Every Time

Here are a few extra tips to ensure your zucchini boats are a delicious success:

• Choose the Right Zucchini: Medium-sized zucchini (about 6-8 inches long) tend to work best. They have fewer large seeds and are less likely to be watery giants. Very large zucchini can have tough skin and a lot of pithy seed area to scoop out.
• Don’t Skip the Salting & Drying: I can’t stress this enough! This is the secret weapon against soggy zucchini. Make sure you give it enough time (at least 15-20 minutes) and then pat them thoroughly dry. It makes all the difference.
• Variations Welcome: This cheesy spinach filling is classic, but feel free to get creative! You could add finely chopped mushrooms, bell peppers, or even some cooked ground beef or chicken to the filling mixture before adding the cheese. Just make sure any additions are cooked and any excess liquid is drained.
• Cheese Swap: Experiment with different shredded cheese blends. Sharp cheddar, Gruyere, or even smoked mozzarella can add fun new flavors.
• Herb It Up: Mix other fresh herbs into the filling besides spinach, like basil, oregano, or thyme, for a different flavor profile.

What to Serve With Cheesy Stuffed Zucchini Boats

These zucchini boats are versatile! As the recipe notes, they make a great side dish. They pair wonderfully with grilled meats like our juicy Grilled Lemon Herb Chicken or Juicy Grilled Meat Skewers. For a vegetarian meal, serve them with a fresh Easy Kale Salad or some crispy roasted potatoes like our Easy Crispy Roasted Potatoes. They’re also substantial enough to enjoy two halves per person as a lighter main course.

Your Cheesy Stuffed Zucchini Boats Questions Answered (FAQ)

Let’s tackle some common questions you might have about making perfect zucchini boats.

Can I use frozen spinach?

Yes, you can, but you MUST thaw it completely first and squeeze out every last drop of moisture. Frozen spinach holds a lot more water than fresh, so this step is even more crucial. Cook it down in the skillet just like fresh, but spend extra time ensuring it’s super dry before adding it to the cheese mixture.

Can I make the filling ahead of time?

Absolutely! You can prepare the filling mixture (Steps 5-8) up to a day in advance. Store it covered in the refrigerator. When you’re ready to assemble, just follow the zucchini prep steps (Steps 2-4, 9), then fill and bake as directed.

How do I store and reheat leftovers?

Store leftover zucchini boats in an airtight container in the refrigerator for up to 3-4 days. To reheat, you can gently warm them in the microwave, but for the best texture (especially the breadcrumbs), reheat them in a preheated oven or air fryer at around 350°F (175°C) until heated through and the cheese is bubbly again.

Can I freeze zucchini boats?

Freezing cooked zucchini can sometimes result in a mushier texture upon thawing. While you can freeze them, the best approach is often to prepare the filling ahead and freeze just the filling. Then, thaw the filling and assemble with fresh zucchini when you’re ready to bake. If you must freeze cooked boats, cool them completely, wrap individually or place in a freezer-safe container, and reheat from frozen or thawed in the oven.

What if I don’t have ricotta cheese?

No problem at all! The recipe notes ricotta is optional. The cheesy spinach filling is still delicious and creamy without it thanks to the shredded cheese blend and Parmesan. If you want some added creaminess but don’t have ricotta, a small amount of cream cheese or even plain Greek yogurt could potentially work in a pinch, though it will alter the flavor slightly.

How can I tell when the zucchini is cooked through?

The zucchini is cooked when it’s tender enough to be easily pierced with a fork, but still holds its shape. Avoid overbaking, which can make the zucchini too soft or mushy, even with the salting trick.
