Tips & Substitutions

For added flavor, consider seasoning the squash with garlic or herbs like thyme before cooking. If you prefer a healthier twist, substitute low-fat sour cream and use vegetable broth instead of cream of chicken soup. You can also add some cooked protein, such as shredded chicken or ground turkey, to make it a complete meal. This casserole is also a great way to use up any excess summer squash from your garden.

Serving Suggestions

This casserole is delicious on its own but pairs beautifully with a simple green salad or crusty bread. For a heartier meal, consider serving it alongside grilled chicken or a light protein of your choice. It also makes a fantastic side dish for any summer barbecue.

Frequently Asked Questions

Can I use frozen squash instead of fresh?

Yes, you can use frozen squash, but be sure to thaw and drain it well to avoid excess moisture in the casserole. Frozen vegetables may require a slightly longer cooking time to ensure they are heated through and tender.

What can I substitute for cream of chicken soup?

You can use a homemade version of cream of chicken soup made with chicken broth, milk, and flour or opt for a store-bought cream of mushroom or cream of celery soup for a vegetarian option.

Can I add other vegetables to this casserole?

Absolutely! Feel free to incorporate other vegetables like spinach, mushrooms, or broccoli for added nutrition and flavor. Just make sure to adjust cooking times based on the vegetables you choose.
