Ingredients:
Preparing the Zucchini
The first step to creating this delicious casserole is preparing our star ingredient: the zucchini. For this recipe, we’ll need about 40 ounces of zucchini. This typically translates to two to three large zucchini. You want to slice them about 1/4 inch thick. Uniform slices are key here, as they will ensure even cooking throughout the casserole. You can use a sharp knife for this, or for extra precision and speed, a mandoline slicer can be a fantastic tool. Just be sure to use the safety guard if you opt for a mandoline! Once sliced, we need to address the excess moisture that zucchini is known for. Place the sliced zucchini in a colander set over a bowl or the sink. Sprinkle the 1 teaspoon of salt evenly over the zucchini slices. The salt will draw out a significant amount of water. Let the zucchini sit in the colander for at least 20 to 30 minutes. You’ll be surprised how much liquid pools at the bottom. After the resting period, gently pat the zucchini slices dry with paper towels. This crucial step prevents your casserole from becoming watery and ensures a more concentrated flavor and pleasing texture.
Building the Creamy Sauce
While the zucchini is doing its water-drawing magic, we can start building the rich, cheesy sauce that will bind everything together. In a large skillet or sauté pan, melt the 2 tablespoons of butter over medium heat. Once the butter is melted and shimmering, add the 5 ounces of diced onion. We want to sauté the onions until they become soft and translucent, which usually takes about 5 to 7 minutes. Stir them occasionally to prevent sticking and to ensure even cooking. This process mellows out their sharp flavor and brings out their natural sweetness. Next, add the 2 cloves of minced garlic to the skillet. Cook the garlic for just about 30 seconds to 1 minute, until it’s fragrant. Be careful not to burn the garlic, as burnt garlic can turn bitter. Now, pour in the ½ cup of heavy cream. Stir everything together, scraping up any browned bits from the bottom of the pan – that’s where a lot of flavor is hiding! Bring the mixture to a gentle simmer. Let it simmer for a few minutes, stirring occasionally, until it thickens slightly. This creamy base is the perfect canvas for our cheeses.
Incorporating the Cheeses
This is where our casserole truly earns its name! With the cream mixture at a gentle simmer, it’s time to add the star cheeses. Remove the skillet from the heat to prevent the cheese from becoming oily. Add 4 ounces of the grated Gruyere cheese and 2 ounces of the grated Parmesan cheese to the warm cream mixture. Stir gently until the cheeses are completely melted and the sauce is smooth and luscious. You want a beautifully emulsified sauce. Taste the sauce at this point and adjust seasoning if needed, though the salt from the zucchini and the savory cheeses usually provide ample flavor. The Gruyere cheese melts beautifully and has a wonderful nutty, slightly sweet flavor that pairs exceptionally well with zucchini, while the Parmesan adds that essential salty, umami depth. We’ve saved some cheese for topping, so don’t add it all in just yet!
Assembling and Baking the Casserole
Now that our zucchini is prepped and our cheesy sauce is ready, it’s time to assemble this delightful dish. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a baking dish (an 8×8 inch or similar sized dish works well). Carefully arrange the dried zucchini slices in an even layer in the prepared baking dish. You can layer them slightly overlapping. Pour the creamy cheese sauce evenly over the zucchini slices, making sure to coat them as much as possible. Gently spread the sauce with a spoon or spatula. Make sure to get into all the nooks and crannies. Finally, sprinkle the remaining 2 ounces of grated Gruyere cheese and 2 ounces of grated Parmesan cheese evenly over the top of the casserole. This cheesy topping will bake to a golden brown, creating a delightful crust. Cover the baking dish tightly with aluminum foil. Bake for 25 minutes. After 25 minutes, carefully remove the aluminum foil. Continue baking for another 15 to 20 minutes, or until the cheese on top is melted, bubbly, and golden brown, and the zucchini is tender when pierced with a fork. The exact baking time will depend on your oven and how thinly you sliced your zucchini.
Resting and Serving
Once your Cheesy Baked Zucchini Casserole is out of the oven, resist the urge to dive in immediately! It’s important to let the casserole rest for about 5 to 10 minutes before serving. This resting period allows the casserole to set up slightly, making it easier to serve and preventing it from being too soupy. The flavors will also meld together beautifully during this time. Serve warm and enjoy the comforting, cheesy goodness. This dish is wonderfully versatile and pairs well with grilled meats, roasted chicken, or as a standalone vegetarian option. Enjoy every delicious bite of this simple yet satisfying casserole!

Frequently Asked Questions:
Can I make this casserole ahead of time?
Absolutely! You can assemble the casserole up to a day in advance. Cover it tightly with plastic wrap and refrigerate. When you’re ready to bake, simply remove it from the refrigerator about 30 minutes before baking to allow it to come closer to room temperature, and then bake as directed, adding a few extra minutes to the cooking time if needed.
My zucchini seems watery. How can I prevent a soggy casserole?
A common issue with zucchini is its high water content. To combat this, after slicing or dicing your zucchini, I recommend salting it. Place the zucchini in a colander set over a bowl, sprinkle generously with salt, and let it sit for at least 20-30 minutes. The salt will draw out excess moisture. Rinse the zucchini thoroughly under cold water and pat it completely dry with paper towels before proceeding with the recipe. This step is crucial for a perfectly textured Cheesy Baked Zucchini Casserole.
