Chicken zucchini casserole is a quick and easy casserole consisting of bite-sized pieces of chicken and zucchini, cheese, tomatoes, and spices. It’s a great weeknight meal!
Absolutely! You can use boneless, skinless chicken thighs in place of the breasts in this recipe. You could also save some prep time by using shredded rotisserie chicken!
Zucchini has high water content, so if you overbake it, the water will seep out and your zucchini will be soggy. You can combat this by cutting the zucchini into larger pieces and laying the cut pieces on paper towels or a kitchen towel for 10-20 minutes to draw out excess moisture.
There’s no doubt that this chicken casserole with zucchini is full of flavor. From the first bite, you’ll get a mouthful of creamy, cheesy goodness!
Make Ahead Instructions
This casserole keeps well for about 3 days in the refrigerator once baked, so you can make it ahead of time and reheat it when you’re ready to enjoy. You can also save time by cooking the chicken in advance and storing it in the refrigerator until you’re ready to assemble and bake the casserole.
Storage Instructions
Store leftover chicken zucchini casserole in an airtight container in the refrigerator for up to 3 days. Reheat in a 400°F oven until warmed through. I do not recommend freezing this casserole.
Substitutions
- You can use vegetable broth in place of the chicken broth.
- Try mixing things up with a different herb! Instead of thyme, try fresh rosemary!
