Step‑by‑Step Instructions for Cheesy Squash and Zucchini Casserole
Step 1: Prepare the Vegetables
Begin by thinly slicing the zucchini and yellow squash into ⅛-inch rounds. Place them in a colander, sprinkle with salt, and toss to ensure equal coating. Let the vegetables sit for 20–30 minutes. This step is crucial for drawing out excess moisture, resulting in a perfectly textured Cheesy Squash and Zucchini Casserole.
Step 2: Blot the Slices
After allowing the zucchini and squash to rest, take a few paper towels and gently blot the slices to absorb any remaining moisture. This ensures that your casserole doesn’t become watery during baking and allows the flavors to meld beautifully.
Step 3: Sauté the Aromatics
In a large skillet, heat the olive oil over medium heat. Once hot, add the diced onion and sauté for about 3–4 minutes until it becomes translucent and soft. Next, stir in the minced garlic and cook for an additional 30 seconds, infusing the oil with a delightful aroma that enhances the flavor of your Casserole.
Step 4: Cook the Squash and Zucchini
Carefully add the blotted squash and zucchini slices to the skillet. Sauté them for 5–7 minutes until they are slightly tender but still have a bit of bite. Once cooked, remove from heat and set aside to cool while you prepare the creamy mixture.
Step 5: Mix the Cream Base
In a large mixing bowl, whisk together the sour cream, mayonnaise, beaten egg, black pepper, thyme, and garlic powder. Combining these ingredients creates a rich and creamy base that melds all the flavors of your Cheesy Squash and Zucchini Casserole together beautifully.
Step 6: Add the Cheeses and Herbs
Next, fold in the shredded sharp cheddar, grated Parmesan, and chopped fresh parsley into the creamy mixture. This step not only contributes flavor but also adds richness to your casserole, ensuring each bite is deliciously cheesy and herbaceous.
Step 7: Preheat the Oven
While preparing the mixture, preheat your oven to 375°F (190°C) to ensure it’s ready when you’re done mixing. Then, grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking and make for an easier cleanup once your Cheesy Squash and Zucchini Casserole is baked.
Step 8: Combine Everything Together
Add the sautéed vegetables to the cheese mixture and gently fold everything together until the squash and zucchini are thoroughly coated. This ensures even distribution of flavors, so every scoop of your casserole is packed with that creamy goodness.
Step 9: Spread in the Baking Dish
Pour the combined mixture into the prepared baking dish, using a spatula to spread everything evenly. This will help the Cheesy Squash and Zucchini Casserole cook evenly throughout, resulting in a beautifully baked dish.
Step 10: Bake Covered
Top the casserole with shredded mozzarella cheese, ensuring a generous layer covers the entire surface. Then cover the dish with aluminum foil to lock in moisture, and bake in your preheated oven for 20 minutes.
Step 11: Remove the Foil and Continue Baking
After 20 minutes, carefully remove the foil and return the casserole to the oven. Bake uncovered for another 15–20 minutes, or until the top is golden and bubbly, and the cheese has melted into an irresistible layer of gooey goodness.
Step 12: Rest and Serve
Once done, remove the casserole from the oven and let it rest for 5–10 minutes before serving. This resting period helps the casserole set slightly, making it easier to slice. Garnish with extra parsley if desired, and your Cheesy Squash and Zucchini Casserole is ready to be enjoyed!
