💭 Tips
Expert Tip: Use smaller, tender squash for summer squash casserole. They don't have to be tiny but make sure the skin is soft and tender.
- Slice it in even slices.
- You can use zucchini if you like.
- Add the sour cream to the squash to cool it off before adding other ingredients.
- Cream cheese is a nice variation for the sour cream. It's a little more dense than when made with sour cream. Warm it so that it stirs in easily.
- Some people use mayonnaise instead of sour cream.
- Some people use a can of cream of mushroom soup instead of sour cream.
- Don't use frozen veggies in a yellow squash casserole because it has too much liquid and makes the finished dish watery.
- You can add diced ham or cooked, diced chicken to make this more of a main dish.
- Store leftovers in the refrigerator for up to three days.
Serve with...
I usually think of this southern yellow squash casserole as a main dish because that's how it was generally served when I was growing up.
As a side dish it goes really well with just about any grilled meat and I love it with meatloaf!
It's so easy to make and really budget friendly - especially in the summer when your neighbors are leaving bags of summer squash and zucchini on your porch!
It's also an unusual side dish for Thanksgiving so keep that in mind!
