Ingredients
To make Chicken and Zucchini Casserole, you'll need these easy-to-find ingredients.
- Chicken Thighs -Thighs work best. They stay juicy, tender, and delicious!
- Zucchini - Can be swapped for yellow squash.
- Onion - Can use a sweet onion, white or red. I suggest a white onion since red can be a bit overpowering for some.

- Seasonings - Salt, Cumin, Garlic, and Oregano.
- Chipotles in Adobo Sauce - Keep these on hand! You'll be surprised how often you use them. They are easily found in the Hispanic section of the grocery store.
- Canned Petite Diced Tomatoes - can also use 3 Roma tomatoes or 1 large tomato
- Mozzarella Cheese - I used a smoked cheese for extra flavor, and it was GREAT! Can also use Parmesan instead.
- Green Onion and Lime - Used for ending flavor and to finish with a topping of lime zest.
