Ingredients:
Preparing the Zucchini
The first step in creating our delicious casserole is to prepare the star of the show: the zucchini. We want to ensure that our zucchini isn’t watery, which can sometimes be a challenge with this versatile vegetable. To combat this, we’ll be salting the sliced zucchini and letting it drain. This process, known as “sweating” the zucchini, draws out excess moisture. Lay your 1/4 inch thick zucchini slices in a single layer on paper towels. Sprinkle them evenly with the 1 teaspoon of salt. Let them sit for about 20-30 minutes. You’ll notice that moisture begin extracts to bead on the surface of the zucchini. After the resting period, gently pat the zucchini slices dry with more paper towels to remove any remaining surface moisture. This crucial step ensures a wonderfully textured casserole, not a soggy one.
Building the Flavor Base
While the zucchini is sweating, we’ll focus on creating a rich and aromatic flavor base. In a skillet over medium heat, melt the 2 tablespoons of butter. Once the butter is melted and shimmering, add the 5 ounces of diced onion. We want to gently sauté the onions until they become soft and translucent, and just begin extractning to caramelize. This process brings out their natural sweetness and adds a wonderful depth of flavor to the casserole. Stir the onions occasionally, which should take about 5-7 minutes. Once the onions are softened, add the 2 cloves of minced garlic to the skillet. Cook for another minute until fragrant, being careful not to burn the garlic, as burnt garlic can turn bitter.
Creating the Creamy Sauce
Now it’s time to bring everything together with a luscious, creamy sauce. Pour the ½ cup of heavy cream into the skillet with the sautéed onions and garlic. Stir to combine and let it simmer gently for about 2-3 minutes. This will allow the cream to thicken slightly and incorporate the flavors of the onions and garlic. Remove the skillet from the heat. Now, we’ll add a generous portion of our cheeses to this creamy mixture. Stir in about half of the grated Gruyere cheese (3 ounces) and half of the grated Parmesan cheese (2 ounces) into the warm cream mixture. Stir until the cheeses are mostly melted and the sauce is smooth and well combined. This will create a wonderfully cheesy and flavorful sauce that will coat the zucchini beautifully.
Assembling the Casserole
With our flavor base and sauce ready, it’s time to assemble our Cheesy Baked Zucchini Casserole. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a baking dish (a 9×13 inch dish is ideal). Arrange the dried, sliced zucchini in an even layer in the prepared baking dish. You can overlap them slightly. Pour the creamy cheese sauce evenly over the top of the zucchini slices, ensuring that each slice is coated. Try to spread it out as much as possible so every bite is infused with that delicious cheesy goodness.
The Cheesy Topping and Baking
For the grand finnon-alcoholic ale, we’ll add the remaining Gruyere and Parmesan cheeses as a glorious topping. Sprinkle the remaining 3 ounces of Gruyere cheese and the remaining 2 ounces of Parmesan cheese evenly over the top of the casserole. These cheeses will melt and brown beautifully in the oven, creating a golden, irresistible crust. Place the baking dish in the preheated oven. Bake for 25-30 minutes, or until the casserole is bubbling around the edges and the cheese topping is melted and golden brown. You can also broil it for the last minute or two for extra crispiness, but watch it very closely to prevent burning. Let the casserole rest for about 5-10 minutes before serving. This allows the flavors to meld and makes it easier to serve neat portions. Enjoy your incredibly delicious and comforting Cheesy Baked Zucchini Casserole!
