Classic Squash Casserole

Summer produce is at its peak right now.

Mid-August is the best time to buy tomatoes, watermelon, peppers, peaches and squash.

The farmer’s market was packed full of produce when we went this weekend. I love perusing the booths for the best of summer’s harvest.

Soon, the booths will close up shop and the produce will switch over to lettuce and gourds. For now, though, I’m trying to make the best with what we have while it’s available.

The best thing to do with summer squash is to make a classic casserole. I’ve been eating squash casserole for years, and I’ve made a few different versions to boot. There’s nothing quite like the classic, though, and this recipe is the ultimate Southern favorite.

There’s Vidalia onions, sharp cheddar, cream of mushroom soup, mayonnaise and Ritz crackers in this recipe. It’s not all good-for-you ingredients, but it’s good for the soul.
