Tips & Substitutions

For a creamier texture, try using Greek yogurt instead of sour cream. You can also replace the yellow squash with zucchini for a slightly different flavor. If you'd like to add some protein, consider mixing in cooked ground turkey or chicken. To save time, use pre-chopped vegetables available at the grocery store. This dish is a great way to use up any extra summer squash from your garden.

For a complete meal, consider serving it alongside baked chicken or fish. This casserole is also a great option for vegetarian recipes, making it a versatile choice for various dietary preferences.

Storage & Reheating

Store any leftover squash casserole in an airtight container in the refrigerator for up to 3 days. To reheat, place it in a preheated oven at 350°F for about 20 minutes or until heated through. You can also microwave individual portions for convenience, but the oven will keep the topping crispy.
