Common Mistakes to Avoid

When making Zucchini & Squash Casserole, it’s easy to overlook some steps. Here are common mistakes and how to avoid them.

• Not removing excess moisture: Failing to dab the zucchini and squash slices after salting can result in a watery casserole. Always let them sit for 10 minutes before patting dry.
• Skipping the foil cover: Baking without covering the dish can lead to uneven cooking. Cover with foil for the first part of baking to ensure even heat distribution.
• Overbaking: Leaving the casserole in the oven for too long can dry it out. Keep an eye on it, especially when broiling, as it can brown quickly.
• Using stale bread crumbs: Stale Panko bread crumbs may not provide the desired crunch. Always use fresh crumbs for a crispy topping.
• Ignoring seasoning: Skimping on salt and pepper can leave your casserole bland. Don’t forget to season each layer adequately.
• Neglecting fresh herbs: Fresh parsley adds flavor and color but is often omitted. Always sprinkle some on top for that extra touch.
