Blanching sounds fancy, like something a chef in a tall hat does while scowling. But it’s just a quick dip in boiling water, then an ice bath. Think of it as a spa day for your squash, but instead of cucumber slices, they get a hot tub and a polar plunge.
You’re basically giving the squash a shock treatment. The boiling water stops the enzymes that would turn your precious veggies into mush. The ice bath locks in that bright color and crisp texture. Without it, frozen squash gets sad and watery—like a forgotten gym sock.
The pre-game: washing and chopping
First, wash your squash like you’re scrubbing a tiny yellow submarine. You don’t need to peel them—the skin is totally fine, and peeling is a hassle when you’ve got thirty squash to process. Just slice off the ends, then cut them into half-inch rounds or chunky cubes.
Be consistent with your cuts. If you chop some pieces thick and some thin, the thin ones will turn to baby food while the thick ones stay crunchy. It’s the Goldilocks principle: even is your friend. Aim for pieces that are all roughly the same size, like a kindergarten class on picture day.
The main event: into the bubbling cauldron
Bring a big pot of water to a rolling boil—and I mean rolling, not a lazy simmer. Add a generous pinch of salt, because even vegetables deserve a little seasoning in their last moments before the deep freeze. Drop in your squash pieces in a single layer, or use a mesh basket if you’re fancy.

Set a timer for exactly three minutes. Three minutes is the sweet spot. Any longer, and you’re cooking them, which defeats the whole point. Any shorter, and the enzymes will laugh at your half-hearted effort. You’ll start humming the “blanching song,” which is just “Three, two, one—go!” on repeat.
While the squash boils, prepare an ice bath. Fill a large bowl with cold water and a tray of ice cubes. Not a few cubes—a glacier’s worth. You want that water to be angry cold, like a penguin’s opinion of summer.
The cold plunge: shock and awe
When the timer beeps, use a slotted spoon or tongs to fish the squash out of the boiling water. Dump them straight into the ice bath. You’ll hear a satisfying hiss as steam meets ice. That sound is the sound of victory. Swish them around for three minutes, until they’re completely cool.
If you skip the ice bath, the residual heat will keep cooking the squash. You’ll end up with a bag of soggy, sad vegetables six months from now. And no one wants a sad vegetable in January—they’re already sad enough about the snow.
