Chicken Zucchini Casserole Ingredients
For the Casserole
- Boneless Chicken Breast – Essential for protein; feel free to use leftover cooked chicken for convenience.
- Zucchini – Adds moisture and nutrition; substitute with roasted bell peppers or fresh spinach for variety.

- Green Onion – Adds a fresh crunch and color; substitute regular onions for a stronger flavor if you like.

Make Ahead Options
These Chicken Zucchini Casserole is perfect for busy weeknights when you want a home-cooked meal without the hassle! You can fully assemble the casserole up to 24 hours in advance by preparing it up to the baking stage, then cover it tightly and refrigerate. This method allows the flavors to meld beautifully while preserving the freshness of your ingredients. When you’re ready to enjoy it, simply bake as directed, adding an extra 5-10 minutes to the cooking time if you’re starting with a cold casserole. For optimal quality, avoid adding the panko breadcrumbs until just before baking to keep them crispy. Enjoy a cozy homemade dinner with minimal effort!

Chicken Zucchini Casserole Recipe FAQs
How do I choose the best zucchini for my casserole?
Absolutely! Look for zucchini that is firm, smooth, and free of dark spots or blemishes. Ideally, choose medium-sized zucchinis, as larger ones tend to be more watery and have more seeds.
What is the best way to store leftovers from my Chicken Zucchini Casserole?
Store leftovers in an airtight container in the refrigerator for up to 3 days. This helps retain the casserole’s creamy texture and flavor. When reheating, gently warm it in the oven to keep it from drying out.
Can I freeze Chicken Zucchini Casserole? If so, how?
Certainly! To freeze, I recommend assembling the casserole without baking it first. Wrap it tightly in plastic wrap and aluminum foil and freeze for up to 3 months. When you’re ready to enjoy, thaw it in the refrigerator overnight, then bake at 350°F (175°C) until heated through, about 25-30 minutes.
What if my casserole turns out too watery?
If the casserole is watery, it may be due to excess moisture from the zucchini. To prevent this, you can salt the sliced zucchini before mixing it into the casserole, allow it to sit for 15-20 minutes, and then pat it dry with a paper towel. This will help reduce moisture and improve the final texture!
Is this recipe safe for people with dietary restrictions?
Great question! This Chicken Zucchini Casserole can be made gluten-free by substituting flour with cornstarch and using gluten-free breadcrumbs. If you have dairy allergies, you can use dairy-free Greek yogurt and omit the cheese or replace it with vegan cheese alternatives. Always double-check ingredient labels for hidden allergens.
