It’s incredibly refreshing, cooks in minutes, and packs a serious nutritional punch for something that’s mostly water and air. We're talking a huge hit of vitamin C for almost zero calories. It's time to give this brilliant brassica the spotlight it deserves.

The crisp, wildly underrated green
Pak choi (or bok choy, they're the same thing) has this wonderful dual personality. The stems are thick, crisp, and juicy like celery, while the leaves are tender and dark like spinach. It's part of the brassica family, a cousin to cabbage and broccoli, but with a much milder, sweeter flavor.
Most of us only meet it in a takeout container, but it's so easy to cook at home and ridiculously good for you. It's a classic 'high-volume, low-calorie' food, meaning you can eat a whole lot of it and feel full for very few calories. It's basically crunchy water, but with a surprise wallop of vitamins.

How to cook it right
The biggest mistake people make with pak choi is overcooking it into a soggy mess. The goal is 'tender-crisp'.
01
Keep it quick.
Whether you stir-fry, steam, or grill it, pak choi cooks in 2-4 minutes. The leaves wilt almost instantly, and the stems just need to lose their raw edge.
02
Cook stems first.
If using larger heads, slice the stems off and start cooking them 1-2 minutes before you toss in the delicate leaves.
03
Try it grilled or roasted.
Slice baby pak choi in half lengthwise, brush with oil, and grill or roast at high heat for a few minutes. The edges get charred and delicious.
04
Eat it raw.
Finely shred the crisp stems and add them to salads or slaws for a fantastic, juicy crunch. The leaves can be used like any other salad green.
05
Pair with a little fat.
A drizzle of sesame oil or olive oil doesn't just add flavor; it helps your body absorb the fat-soluble vitamins present in the greens.

MushroomsUMAMI
Shiitake or cremini mushrooms add a deep, savory umami flavor and meaty texture that complements the crisp pak choi.

A splash of soy sauce (or tamari) for saltiness and a dash of rice vinegar for brightness lifts all the other flavors.
