Step-by-Step Instructions

Follow these detailed instructions to make the perfect cheesy zucchini casserole:

Step 1: Prepare the Zucchini

1. Wash the zucchini thoroughly under cold running water.
2. Trim off the ends of the zucchini.
3. Slice the zucchini into ¼-inch thick rounds. You can use a mandoline slicer for even slices, but a knife works just fine.
4. Place the zucchini slices in a colander and sprinkle with salt. This will help to draw out excess moisture. Let it sit for about 20-30 minutes, then rinse with cold water and pat dry with paper towels.

Step 2: Sauté the Vegetables

1. Peel and chop the onion into small dice.
2. Mince the garlic. You can use a garlic press or chop it finely with a knife.
3. In a large skillet, melt the butter over medium heat.
4. Add the chopped onion and cook until softened, about 5-7 minutes.
5. Add the minced garlic and cook for another minute until fragrant, being careful not to burn it.

Step 3: Make the Cheese Sauce

1. Sprinkle the flour over the sautéed onions and garlic. Cook for 1-2 minutes, stirring constantly to create a roux. This will help to thicken the sauce.
2. Gradually whisk in the milk, making sure to break up any lumps. Continue whisking until the sauce is smooth.
3. Bring the sauce to a simmer, stirring constantly, until it thickens slightly, about 3-5 minutes.
4. Remove the skillet from the heat and stir in the shredded cheddar cheese until it is melted and smooth.
5. Season the cheese sauce with salt, pepper, and Italian seasoning to taste. Be sure to taste and adjust the seasoning as needed.

Step 4: Assemble the Casserole

1. Preheat your oven to 350°F (175°C).
2. Lightly grease a 9×13 inch baking dish with butter or cooking spray.
3. In a large bowl, combine the sliced zucchini, cheese sauce, and half of the grated Parmesan cheese. Mix well to ensure that the zucchini is evenly coated with the sauce.
4. Pour the zucchini mixture into the prepared baking dish and spread it out evenly.

Step 5: Prepare the Topping

1. In a separate bowl, combine the bread crumbs and the remaining grated Parmesan cheese.
2. Sprinkle the bread crumb mixture evenly over the top of the zucchini casserole.
3. Drizzle with a little melted butter for extra crispness (optional).

Step 6: Bake the Casserole

1. Bake the casserole in the preheated oven for 25-30 minutes, or until the topping is golden brown and the casserole is bubbly.
2. Remove the casserole from the oven and let it cool for a few minutes before serving.

Tips for the Perfect Cheesy Zucchini Casserole

* **Don’t Skip the Salting:** Salting the zucchini helps to draw out excess moisture, which will prevent the casserole from becoming watery.
* **Use Fresh Ingredients:** Fresh zucchini, cheese, and herbs will give you the best flavor.
* **Don’t Overcook the Zucchini:** Overcooked zucchini can become mushy. Aim for tender-crisp.
* **Adjust the Seasoning:** Taste the cheese sauce and adjust the seasoning as needed. You may want to add more salt, pepper, or Italian seasoning to suit your taste.
* **Customize the Cheese:** Feel free to experiment with different types of cheese. Monterey Jack, mozzarella, Gruyere, or a blend of cheeses would all work well.
* **Add Some Heat:** For a spicy kick, add a pinch of red pepper flakes to the cheese sauce.
* **Make it Gluten-Free:** Use gluten-free bread crumbs to make this casserole gluten-free.
* **Add Protein:** Diced ham, bacon, cooked sausage, or shredded chicken can be added to the casserole for a heartier meal.
* **Prep Ahead:** You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add the topping just before baking.

Variations and Add-ins

* **Mediterranean Zucchini Casserole:** Add sun-dried tomatoes, Kalamata olives, and feta cheese for a Mediterranean twist.
* **Mexican Zucchini Casserole:** Add diced tomatoes, corn, black beans, and chili powder for a Mexican-inspired casserole. Top with shredded Monterey Jack cheese and a dollop of sour cream.
* **Vegetarian Zucchini Casserole:** Add other vegetables like bell peppers, mushrooms, or spinach to make it a more substantial vegetarian meal.
* **Zucchini and Corn Casserole:** Combine zucchini with sweet corn kernels for a delightful summer side dish.
* **Cheesy Zucchini and Rice Casserole:** Mix cooked rice with the zucchini and cheese sauce for a heartier casserole.
* **Zucchini and Tomato Casserole:** Layer sliced zucchini and tomatoes with cheese sauce for a colorful and flavorful dish. A rustic approach is to bake this in a cast iron skillet.
* **Garlic Herb Zucchini Casserole:** Add fresh herbs like basil, oregano, and thyme to the cheese sauce for a more intense herbal flavor. Consider roasting the garlic before incorporating it into the sauce for a richer taste.
* **Crumbled Sausage Zucchini Casserole:** Cook Italian sausage separately, drain off excess grease, and mix it into the zucchini and cheese mixture for a savory, meaty casserole.
