Chef's Tips

Ensure that the zucchini is not overly watery by patting it dry before layering.
Feel free to add other vegetables like bell peppers or spinach for extra nutrition.
You can substitute chicken with turkey or make it vegetarian by omitting the meat.

Troubleshooting

If the casserole is watery, make sure to drain any excess liquid from the tomatoes.
If the top is not browning, you can broil it for a few minutes at the end.

Recipe Variations

Add different types of cheese like cheddar or feta for a flavor twist.
Incorporate other meats such as diced ham or sausage.

Healthy Alternatives

Use low-fat cheese for an even lighter version.
Swap olive oil for coconut oil or a cooking spray to reduce calories.

Serving Suggestions

Serve with a side salad dressed with lemon vinaigrette.
Pair with cauliflower rice or a slice of whole-grain bread.
