Chow Mein vs. Lo Mein: What's the Difference?
| Chow Mein | Lo Mein | |
|---|---|---|
| Noodle type | Wheat-and-egg noodles, thin and crimped, deep-fried or pan-fried until crisp or crisp-edged | Wheat-and-egg noodles, thicker and round, boiled then tossed, always soft and chewy |
| Noodle texture | Crispy or crunchy (Hong Kong style) or crisp-edged with a soft center (pan-fried style) | Soft, springy, and chewy throughout |
| Cooking method | Noodles are boiled, then fried in oil, sometimes twice, until browned | Noodles are boiled, then stir-fried briefly with sauce and other ingredients |
| Sauce distribution | Sauce mostly coats the vegetables and protein, noodles stay drier and crisper | Sauce coats the noodles directly, so every strand is glossy and seasoned |
| Typical vegetables | Cabbage, bean sprouts, carrots, celery, onion | Cabbage, bok choy, mushrooms, carrots, sometimes bean sprouts |
| Common protein | Chicken, shrimp, beef, or pork, cut thin and stir-fried fast | Same range of proteins, often cut slightly larger since the dish is less about crunch |
| Regional origin | Guangdong-style Chinese cooking, popular across Chinese-American takeout | Shanghai and northern Chinese cooking, also widespread in Chinese-American takeout |
Verdict
Choose chow mein when you want texture and crunch, the noodles are fried and hold up against a punchy sauce on the vegetables. Choose lo mein when you want every strand of noodle soft, chewy, and fully coated in sauce.
Chow Mein
Chow mein starts with fresh wheat noodles that are boiled briefly, then fried in a hot wok or pan with oil until they crisp up, either fully crunchy (Hong Kong style, often served as a base under a saucy stir-fry) or crisp on the bottom with a chewier top (the more common Americanized pan-fried version). Because the noodles absorb less sauce during frying, the seasoning concentrates on the cabbage, bean sprouts, and protein instead.
Lo Mein
Lo mein noodles are thicker and rounder than chow mein noodles, and they skip the frying step entirely. After boiling, they go straight into the wok with sauce, vegetables, and protein and get tossed, not fried, just long enough to heat through and pick up color. The result is a soft, chewy noodle that's slick with sauce from edge to edge, which is why lo mein reads as the saucier, more noodle-forward dish of the two.
FAQ
Do chow mein and lo mein use the same noodles?
They start from the same fresh wheat-and-egg noodle, but chow mein noodles are usually thinner and get boiled then fried, while lo mein noodles are thicker, rounder, and only boiled, never fried.
Which one has more sauce?
Lo mein, because the noodles themselves are tossed directly in the sauce; chow mein noodles are fried first, so they stay drier and the sauce clings mainly to the vegetables and protein.
Is chow mein always crispy?
Not always. Hong Kong-style chow mein is fried until fully crisp and crunchy, but Americanized pan-fried chow mein is usually just crisp on the bottom with a softer top layer.
Which is lower in calories, chow mein or lo mein?
Chow mein, on average, since frying the noodles adds oil but a smaller total noodle volume per serving compared to lo mein's heavier, sauce-coated noodle base.
Can I substitute one noodle for the other in a recipe?
Yes, in a pinch. Swap in dried spaghetti or linguine for lo mein noodles if fresh ones aren't available, and use thin egg noodles or even ramen noodles (discard the seasoning packet) for chow mein.
