A Delicious Summer Casserole for Late Summer or Early Fall
Casseroles and summer may not seem like a natural fit, but this one is perfect for your late summer or early fall table. With cooler Bay Area temps this week, I paired this favorite side dish with grilled sausage for a cozy mid-weeknight meal. It’s a family recipe passed down by a dear family friend, which I’ve updated to suit my family’s tastes.
Simple, Fresh, and Easily Adaptable
This casserole combines fresh, seasonal ingredients with a flavorful, creamy base. Plus, it’s versatile:
- Brown rice can replace white rice.
- Yellow squash works as a substitute for zucchini.
- Use cherry tomatoes instead of regular tomatoes.
- Any bell pepper color works great.
- Sour cream works as a substitute for creme fraiche but tends to curdle due to the high heat. Flavor is unchanged, however.
To save time, use prepared frozen rice—it’s a shortcut I often take. Trader’s Joe’s is where I stock up!
I hope you give this summer casserole a try and love it.
Cheers,
