Tips & Substitutions

For a more flavorful zucchini casserole, consider adding fresh herbs like basil or thyme. If you want to reduce fat, you can substitute half of the oil with unsweetened applesauce. For a gluten-free version, try using a gluten-free baking mix instead of Bisquick. Make sure to slice the zucchini thinly for even cooking and a tender texture.

Serving Suggestions

This zucchini casserole pairs beautifully with a fresh garden salad or steamed vegetables for a well-rounded meal. You might also serve it alongside grilled chicken or fish for added protein. Consider topping each serving with a dollop of sour cream or a sprinkle of additional Parmesan cheese for extra flavor.

Storage & Reheating

To store leftovers, allow the casserole to cool completely, then transfer it to an airtight container and refrigerate for up to three days. To reheat, preheat the oven to 350°F and heat the casserole for about 15-20 minutes or until warmed through. You can also microwave individual portions for convenience.
