Summer Squash Casserole Recipe

This delicious savory side dish is a tasty alternative to steamed vegetables that will keep you coming back for more.  It’s also a great topping for Zone PastaRx Orzo. In fact, you might want to double or triple the recipe so there’s enough for leftovers!   

I designed this recipe from my memories of a family favorite, comfort food made by my Aunt.  It was always on the table year-round at every family gathering. We used to consider it a vegetable dish but in truth, it contained an entire bag of stuffing mix plus a large container of sour cream!  Looking back, I’d call the original version a stuffing casserole with some summer squash and shredded carrot in it. Now before you get too excited, there’s no stuffing in my version but I’ve added just a bit of cheese to keep things interesting.  I use a very low carbohydrate condensed portobello mushroom soup without artificial additives and light sour cream that’s extremely low in fat. I think my Aunt would have loved this version as much as we all loved hers!   

 Tips 

  • This recipe can be made ahead of time, stored in the fridge, and reheated. 
  • Don’t hesitate to be a little heavy-handed with the seasonings.  They’re what makes this dish. 
  • Be a smart consumer and read your labels closely.  You’ll be surprised by the differences in ingredients between brands, especially when it comes to condensed soups and low-fat dairy products.  Avoid those that are loaded with fillers, starches, and saturated fats.
