Preparation and Baking

Step 1: Preparing the Zucchini

The first crucial step in making this delicious casserole is to prepare the zucchini. You’ll want about 40 ounces of zucchini, which typically translates to 2-3 large zucchini. Wash them thoroughly and then slice them about 1/4 inch thick. Uniform slicing is important so that the zucchini cooks evenly. As you slice, place the zucchini in a colander set over a bowl or the sink. Sprinkle the 1 teaspoon of salt evenly over the sliced zucchini. Salt helps to draw out excess moisture from the zucchini. This is a very important step to prevent a watery casserole. Let the zucchini sit and drain for at least 15-20 minutes. You’ll be surprised how much liquid is released. After the draining period, gently pat the zucchini dry with paper towels. This will help remove any remaining surface moisture.

Step 2: Sautéing the Aromatics

While your zucchini is draining, it’s time to build the flavor base for our creamy sauce. In a large skillet, melt the 2 tablespoons of butter over medium heat. Once the butter is melted and shimmering, add the 5 ounces of diced onion. Cook the onions, stirring occasionally, until they become softened and translucent, which should take about 5-7 minutes. You don’t want them to brown, just to become tender. Next, add the 2 cloves of minced garlic to the skillet. Cook the garlic for another minute until fragrant. Be careful not to burn the garlic, as it can turn bitter. The aroma of the sautéed onions and garlic is the first sign of the deliciousness to come!

Step 3: Creating the Creamy Sauce

Now, we’ll bring everything together to create the luscious sauce. Pour the ½ cup of heavy cream into the skillet with the sautéed onions and garlic. Stir well to combine. Allow the cream to heat through, but don’t let it boil vigorously. Once the cream is warm, it’s time to introduce the cheese. Add 3 ounces of the grated Gruyere cheese and 2 ounces of the grated Parmesan cheese to the skillet. Stir continuously until the cheeses are melted and the sauce is smooth and creamy. This mixture will be rich and decadent. Taste the sauce at this point and adjust seasoning if needed, though the salt from the zucchini and the savory cheeses often provide enough flavor.

Step 4: Assembling the Casserole

Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a 9×13 inch baking dish with butter or cooking spray. Now, it’s time to assemble the casserole. Arrange a layer of the patted-dry zucchini slices in the bottom of the prepared baking dish. You can overlap them slightly. Pour about half of the cheesy cream sauce evenly over the zucchini layer. Then, add another layer of zucchini slices on top, followed by the remaining half of the cheesy sauce. Make sure to spread the sauce as evenly as possible to coat all the zucchini. This layering technique ensures that every bite is infused with cheesy goodness.

Step 5: The Cheesy Topping and Baking

To finish off our casserole, we’ll add a final, glorious layer of cheese. Sprinkle the remaining 3 ounces of grated Gruyere cheese and 2 ounces of grated Parmesan cheese evenly over the top of the casserole. This will create a beautiful, golden-brown, and bubbly crust as it bakes. Cover the baking dish tightly with aluminum foil. Place the covered casserole in the preheated oven and bake for 25 minutes. After 25 minutes, carefully remove the aluminum foil. Continue to bake, uncovered, for another 15-20 minutes, or until the top is golden brown and the casserole is bubbling around the edges. The zucchini should be tender when pierced with a fork. Let the casserole rest for about 5-10 minutes before serving. This resting period allows the casserole to set slightly, making it easier to serve and preventing it from being too runny. Enjoy this wonderfully cheesy and satisfying zucchini creation!
