📖 Make it your own: yummy variations

1. Main dish energy: Mix in cooked chicken or ham for a more filling main dish.
2. Extra Veggies: Add sliced zucchini, carrots, or even broccoli for more color and flavor.
3. Different Cheeses: Try using Parmesan cheese or Swiss for a different taste.
4. Switch it: Use zucchini instead of crookneck squash.
5. Rich it up: Cream cheese is a nice variation for the sour cream. It's a little more dense than when made with sour cream. Have it at room temperature or warm it slightly so that it stirs in easily.
6. Mayo maybe: Some people use mayonnaise instead of sour cream. I don't care for it that way but you might like it.
7. Soup swap: Some people use a can of cream of mushroom or cream of chicken soup instead of sour cream in this.
8. Crumby: Use bread crumbs instead of the buttery cracker crumbs on the top of the casserole.

2. Room Temperature Ingredients: Let the sour cream and cream of chicken soup come to room temperature for easier mixing.
3. Even Cooking: Spread the squash mixture evenly in the baking dish to ensure even cooking.
