Common Mistakes to Avoid

When making your Zucchini & Squash Casserole, it’s easy to overlook some key details. Here are common mistakes to avoid for the best results.

• Bold slicing technique: Cutting the zucchini and squash too thickly can lead to uneven cooking. Aim for uniform ¼-inch slices to ensure they cook evenly and blend well in the casserole.

• Bold seasoning oversight: Neglecting to season the vegetables adequately can result in a bland dish. Be sure to sprinkle salt and pepper generously for maximum flavor.

• Bold skipping moisture removal: Failing to remove excess moisture from the zucchini can make your casserole watery. Let them sit with salt for 10 minutes, then dab with a paper towel.

• Bold neglecting the broil step: Not broiling at the end can leave your topping soft instead of crispy. Always finish with a high broil for that golden-brown crust.

• Bold rushing cooling time: Serving the casserole too hot can cause it to fall apart. Allow it to cool slightly before serving for better presentation and flavor enhancement.

• Bold improper storage: Storing leftovers improperly can reduce their quality. Ensure you use the right containers and techniques for optimal freshness.
