You're prepping a stir-fry and the choy sum you counted on isn't at the market. The recipe called for it because choy sum adds tender-crisp texture and a subtle bitter note that balances rich sauces.
Without it, the dish loses that fresh crunch and bright green contrast. Most leafy greens wilt too fast or taste too mild.
For stir-fries and steaming, we reach for baby bok choy or tat soi first-both deliver tender-crisp texture and mild bitterness. The main risk is texture mismatch: some greens lack the crunch choy sum provides in high-heat cooking. When choosing, match the stem thickness and cooking time to your dish.

1. Baby Bok Choy 🥬
Baby bok choy sits closest to choy sum in flavor and texture. It brings tender leaves, crisp stems, and a mild sweetness with just a hint of bitterness.
Use 1:1 by volume in any dish calling for choy sum. The stems stay crunchy through stir-fries and steaming.
- ✅ Tender-crisp texture matches choy sum
- ⚠️ Slightly sweeter-add a pinch of salt to balance
The stems are thicker than choy sum's, so split them lengthwise if they're over 1 inch wide. That way they cook evenly.

2. Gai Lan (Chinese Broccoli) 🥦
Gai lan handles high heat without wilting. The stems bring serious crunch and the leaves add a stronger bitter flavor than choy sum.
Use 1:1 by volume in stir-fries and steamed dishes. Expect a more pronounced bitter edge.
Peel the thick stems if they're over ½ inch across. Otherwise they stay tough even after cooking.
- 🍳 In stir-fries: Add stems 2-3 minutes before leaves
- ⚠️ Bitterness: More intense than choy sum-not ideal for mild dishes

3. Tat Soi 🌿
Tat soi offers mild bitterness and tender-crisp texture without thick stems. The leaves are smaller and more delicate than choy sum.
Use 1:1 by volume in salads, quick sautés, or steaming. It cooks faster than choy sum because the leaves are thinner.
Add tat soi in the last 30-60 seconds of stir-frying. Longer heat turns it limp and dull green.
The small leaf size means less visual impact in composed dishes. But the flavor stays close enough that most dishes won't notice.
- ✅ Mild bitter flavor matches well
- ✅ Works raw or lightly cooked
- ⚠️ Wilts faster than choy sum
- ⚠️ Less visible stem crunch
4. Spinach 🥗
Spinach brings mild vegetal flavor and soft texture. It lacks the crunch and bitterness choy sum provides.
Use 1:1 by volume in raw salads or gentle sautés where you don't need crisp stems. Skip it in stir-fries-it collapses in seconds.
Spinach works best as a last-minute addition. Stir it in just before serving so it stays bright green.
The leaves wilt almost instantly under heat, so you won't get the tender-crisp bite choy sum delivers.
But in dishes where texture isn't critical, spinach keeps the green color and adds a gentle leafy note. Baby spinach works better than mature spinach because the leaves are smaller and more tender.
If you need crunch, this isn't the swap-but for soups, quick braises, or salads, it's fine. Need other greens?
Here's what to use for Spinach when you're building a swap.
5. DIY Greens Mix 🔧
Mix equal parts baby spinach and watercress leaves with ¼ volume chopped kale stems per cup of choy sum needed. The kale stems mimic choy sum's crunch while the leaves add mild bitterness.
Use this blend in stir-fries where you need texture complexity. The uneven leaf sizes don't matter much once everything's cooked.
Chop the kale stems into ½-inch pieces so they cook through in the same time as the leaves. Add them first, then toss in the spinach and watercress after 1-2 minutes.
The watercress brings a peppery bite that sits close to choy sum's bitterness. Spinach softens the intensity and adds bulk.
The result isn't identical, but it covers the main functions: crunch, color, and a hint of bitterness.
This works best when you're already building a stir-fry with strong sauces that can absorb slight flavor differences. For more greens combinations, check out Spinach substitutes ranked.
Which Choy Sum Swap to Grab
- For stir-fries: Baby bok choy or gai lan bring the crunch and heat tolerance
- For salads: Tat soi or spinach work raw without cooking
- For steaming: Baby bok choy stays closest to the original texture
Frequently Asked Questions
Yes, regular bok choy works at 1:1 ratio. The stems are thicker and sweeter than choy sum, so split them lengthwise for even cooking. Expect slightly less bitterness and more crunch.
Choy sum has thinner stems and more bitterness. Baby bok choy runs sweeter with thicker, crunchier stalks. Both work in the same dishes, but choy sum brings a sharper green flavor.
Kale's too tough and bitter for a direct swap. If you use it, blanch the leaves for 2 minutes first and remove the thick ribs. It won't match choy sum's tender texture, but it'll work in soups and long braises.
Choy sum works both ways. Raw, it's crisp and mildly bitter-great in salads. Cooked, it softens but keeps some crunch. Most recipes call for quick cooking like stir-frying or steaming.
Wrap unwashed greens in damp paper towels and store in a plastic bag in the crisper. Baby bok choy and gai lan last 5-7 days. Spinach and tat soi wilt faster-use within 3-4 days.
