Common Mistakes to Avoid
To perfect your Chicken Zucchini Casserole, watch out for these common pitfalls.
- Skipping the Preheat: Not preheating your oven can lead to uneven cooking. Always preheat to ensure that your casserole cooks properly from the start.
- Overcooking Zucchini: Cooking zucchini too long before baking can make it mushy. Sauté just until slightly tender for the best texture.
- Ignoring Seasoning: Under-seasoning the dish can result in bland flavors. Taste and adjust salt, pepper, and spices to enhance the overall taste.
- Using Cold Ingredients: Adding cold ingredients can slow down cooking time. Allow chicken and dairy products to come to room temperature before mixing.
- Neglecting Topping Texture: A soggy breadcrumb topping isn’t appealing. Ensure breadcrumbs are mixed with melted butter for a crispy finish.
