What’s the difference between yellow squash and green squash?
Yellow squash is a type of summer squash, much like green squash, which has a thin, edible skin. They’re usually picked before the skin has a chance to thicken up and become inedible like the squash skin on things like acorn or butternut squash!

Here’s what you’ll need to make a chicken and yellow squash casserole:
This recipe uses boneless skinless chicken breasts but you can use whatever you have on hand. If you have cooked chopped or shredded chicken on hand already, even better.
A nice hack for this recipe is to just grab a rotisserie chicken that’s cooked and you can add that into the casserole for a full meal that’s ready in no time!
We will also be using yellow squash, olive oil, chicken or veggie broth, onions, sour cream, cream of mushroom soup (substitute another cream of style soup if you need to), along with some chicken flavored stuffing mix, butter, and salt and pepper!

This recipe is pretty simple and it has simple ingredients. That’s part of the magic of it all. This recipe comes together easily and quickly so that you don’t have to overthink meal times!
How to make a squash and chicken casserole:
Cook the chicken, cool completely, cut into 2” pieces and set aside.
Bring squash to boil in broth and cook for 8 minutes.
Drain and combine all vegetables.

Combine sour cream, soup and salt and pepper.
Add the chicken and veggies to the mixture.
Spoon all of that into a lightly greased 9×13” baking dish.
Combine the stuffing and the butter and then sprinkle it over the top of the casserole.
Bake at 350 degrees F for 25 minutes.

I had four large squash in the fridge...hence why i tried this one. I added a small can of green chiles and a bag of shredded cheese. It was really good!
