There’s something really practical about keeping a couple of squash in the fridge. They cook quickly, don’t require much prep, and go with almost anything. This yellow squash and zucchini stir-fry is one of those simple side dishes I lean on when dinner feels incomplete but I don’t want to start something complicated.
It’s just butter, olive oil, fresh squash, salt, and pepper — finished with a little grated Parmesan if I’m in the mood. The edges turn lightly golden, the centers stay tender, and the whole thing comes together in about 20 minutes.
Table of Contents
I first made this as a last-minute side for grilled chicken. I had two small zucchini and a couple of yellow crookneck squash that needed to be used. Instead of roasting them, I tried sautéing them in a wide skillet without stirring too much at first. That quick sear made all the difference.
Since then, it’s been a regular in my kitchen — especially during warmer months when squash is easy to find and affordable.
