Calories In Bok Choy: Raw, Cooked, And Serving Sizes

Bok choy is a leafy member of the cabbage family with crisp white stalks and tender green tops. It’s low in calories and high in water, so the calorie count stays tiny while the volume looks generous on the plate. The exact number depends on how you measure a serving and whether it’s raw or cooked.

Here’s a quick table to convert common servings into calories. This lands close to the top of the page so you can size portions fast without scrolling around.

Serving	Approx. Weight	Calories
Raw, 1 cup, shredded	70 g	~9 kcal
Raw, 100 g	100 g	~20 kcal
Raw, 1 leaf	~14 g	~2 kcal
Raw, 1 head (medium)	~840 g	~109 kcal
Cooked (boiled, drained), 1 cup	170 g	~20 kcal

Those numbers are tiny because bok choy is mostly water with small amounts of carbohydrate, protein, and fat. If you’re tracking energy intake, portions feel generous once you set your daily calorie needs, since a full cup barely nudges the total.

How We Counted Calories For Bok Choy

The calorie estimates come from standardized nutrition entries for raw Chinese cabbage (pak choi) and its cooked form. A 1 cup shredded raw serving is about 70 grams and lands around 9 calories, while 100 grams of raw bok choy sits near 20 calories. A cooked cup (boiled and drained) weighs more because it holds water, yet it still comes in near 20 calories per cup thanks to the low energy density.

These entries list macronutrients and micronutrients for each serving size. Raw bok choy per cup contains roughly 0.7 grams of fiber and a helpful dose of vitamin C and folate. Cooked bok choy per cup delivers more vitamin A per bite because the leaves wilt down, so you eat more of them at once. The energy stays modest in both cases, which is why bok choy is handy for building volume into meals.

Raw Vs. Cooked: What Changes?

Cooking softens the stalks, concentrates flavor a bit, and changes how many leaves fit in a cup. A raw cup weighs about 70 grams, while a cooked cup weighs closer to 170 grams, so the cooked cup often carries more vitamins per measuring cup simply because there’s more plant matter in there. Calories still stay low since water weight drives the difference.

Quick stir-fries and soups keep the crunch in the stems and the tenderness in the leaves. Boiling and draining work, too, though seasoning after draining helps keep flavor lively without excess oil.

Serving Size Tips That Keep Calories Low

Think of bok choy as a volume booster. Fold it into noodle bowls, dumpling fillings, tofu scrambles, fried rice, or broth-based soups. Shred the stems thin for a slaw-style salad with a lime-soy dressing. Add a handful at the end of a stir-fry to soften the leaves without losing color. These tricks add heft and satisfaction to plates while keeping calories modest.

For batch prep, slice several heads at once. Store the stems and leaves separately; the stems can handle a few extra minutes of heat while leaves need far less time. That simple split helps keep texture snappy and the overall dish light.

Bok Choy Calories In Everyday Meals

Real-world dishes show how small the calorie toll stays when bok choy is the star. A cup of raw leaves folded into soup adds under 10 calories. Even a hearty cooked cup adds only about 20 calories. Where numbers climb is the sauce and the oil. A tablespoon of neutral oil adds ~120 calories; a nut-based sauce can add more. Smart seasoning goes a long way: garlic, ginger, scallions, black pepper, a splash of soy, or a drizzle of toasted sesame oil right at the end.

If you like richer textures, thicken sauces with a little cornstarch slurry instead of extra oil. Or top a bowl with toasted sesame seeds for crunch; they add calories, but the portion is easy to measure by the teaspoon.

Nutrition Snapshot Beyond Calories

Calories tell only part of the story. A cup of raw bok choy brings vitamin C and folate with minimal sodium. It also contributes vitamin K, which matters for bone health and normal clotting. If you take a blood thinner that interacts with vitamin K, keep intake steady day to day and ask your care team for the plan that fits your prescription; the NIH vitamin K fact sheet explains why consistency matters.

Minerals show up, too. Raw servings add potassium and a touch of calcium and magnesium. Cooked cups can deliver more of those per spoonful because more leaves fit in. Either way, you’re getting a low-calorie vegetable with fiber and a wide set of micronutrients.

Buying, Storing, And Prepping For Accurate Counts

Pick bunches with firm, white stalks and perky green leaves. Rinse well to remove grit near the base. Pat dry and store in a produce bag with a paper towel to trap excess moisture. Use within a few days for the best snap. When you prep, trim the base, separate stalks, and slice. Keep stalks and leaves in separate piles to fine-tune cooking time and preserve texture.

When you want precise tracking, weigh portions after slicing. If you’re measuring by the cup, level the shreds lightly rather than packing them tight. That keeps your cup close to the typical 70-gram raw serving.

Calorie Math In The Kitchen

Here’s a simple way to tally as you cook. Start with the base calories from bok choy using the table above. Then add the extras: oil, sauce, toppings, and sides. Use teaspoons for oil when sautéing, then finish with aromatics for flavor. Soy sauce or tamari adds sodium; go light and layer acid with rice vinegar or citrus to balance. A little toasted sesame oil at the end delivers aroma without much volume.

Common Questions About Bok Choy Calories

Does Baby Bok Choy Change The Count?

Baby bok choy tastes milder and cooks faster, but the calories per weight are similar. The heads are smaller, so a “per head” serving can look lower simply because the head weighs less. For consistency, use grams or cups when you track.

What If I Grill Or Roast It?

Dry-heat cooking drives off water and can concentrate flavor. The raw vegetable still starts near 20 calories per 100 grams. Any big jump comes from oil brushed on the leaves or sauces added after cooking. If you like char, use a light spray of oil and finish with a squeeze of lemon.

Do Toppings Move The Needle?

Sesame seeds, peanuts, cashews, or fried shallots add crunch and richness. Portion these carefully; the vegetable base stays lean, but toppings add calories fast. Measure spoons, not handfuls, and you can keep totals predictable.

Putting It All Together: Low-Calorie Meal Ideas

Five-Minute Skillet Side

Heat a slick of oil in a hot pan, add sliced stems for two minutes, then toss in leaves with garlic and a splash of soy. Finish with black pepper and a few drops of sesame oil. You’ll get a pile of greens for minimal calories.

Brothy Noodle Bowl

Simmer broth with ginger and scallions, drop in sliced stems, then add leaves and noodles. Top with soft tofu or a jammy egg. The broth delivers comfort, while bok choy provides volume for a light total.

Crunchy Slaw

Shred stalks thin and toss with lime juice, a touch of sesame oil, and a pinch of salt. Fold in cucumber and herbs. It’s crisp, refreshing, and simple to scale for meal prep.

Portion Planning For Goals

If your day calls for a lower-energy lunch, two cups of cooked bok choy plus lean protein can make a filling base. The greens contribute fiber and water, which helps satiety at minimal calorie cost. On strength-training days, keep the greens and layer in carbs and protein while you track totals. A few steady habits—measuring oil, salting at the end, and leaning on aromatics—keep flavors big and calories steady.

For a simple template, match one cooked cup of bok choy with one palm-size protein and a cupped-hand portion of cooked grains. It’s easy to remember and easy to scale for family meals or solo dinners.
