Rad na: noodles with gravy compared with pad see ew

The short answer

Rad na and pad see ew usually start with the same ingredient: wide, flat rice noodles. The difference is what happens next. Rad na noodles are served with a separately made, cornstarch-thickened gravy poured over them, so the dish is saucy and spoonable. Pad see ew noodles are stir-fried with soy sauce until they caramelize in the pan, so the dish is drier and the flavor clings directly to the noodles. If you want noodles under gravy, order rad na. If you want soy-seared noodles with no sauce pooling on the plate, order pad see ew.

Rad na, lad na and other spellings

In Thai, the dish is written ราดหน้า. Because Thai is transliterated into English in several ways, menus and recipes spell it differently. All of the following refer to the same gravy-noodle dish:

• Rad na
• Rad naa
• Lad na
• Lad nar
• Lard nad
• Lad nard
• Lawd na

The search phrase "pad lad nah" seems to blend pad see ew with lad na. On a menu, the gravy dish is normally listed under one of the rad na or lad na spellings above, not with "pad" in front.

Side-by-side comparison

Feature	Rad na / lad na	Pad see ew
Noodles	Wide rice noodles	Wide rice noodles
Defining technique	Noodles topped with a separately cooked, thickened gravy	Noodles stir-fried and caramelized in the pan with soy sauce
Texture on the plate	Saucy; noodles sit in or under gravy	Drier; sauce is absorbed and seared onto the noodles
Typical vegetables in documented versions	Carrots, baby corn, leafy greens such as collard greens	Chinese broccoli, mushrooms
Protein options in documented versions	Pork, chicken or seafood	Beef, chicken, pork or tofu

The vegetable and protein rows reflect the specific versions described by two cooks, Nart for rad na and Lane for the comparison with pad see ew. They are not fixed rules. Restaurants vary their vegetables and proteins, so judge the two dishes by the gravy-versus-stir-fry difference and check each menu's listed ingredients separately.

How the taste differs

Pad see ew tastes of soy sauce and a little sugar that has caramelized onto the noodles in a hot pan. Rad na can share some of that flavor, because some cooks brown the noodles with sweet soy sauce before plating. Its main flavor, though, comes from the gravy. In Nart's version, the gravy is seasoned with fermented soybean paste, fish sauce and sugar, which gives it a savory taste. The gravy also softens the noodles' seared edges as you eat.

Rad na is often adjusted at the table. Nart suggests offering fish sauce, vinegar, sugar and chili flakes so each person can season their own bowl.

One documented way to make rad na

Nart's home version shows how the dish is built. The noodles and gravy are prepared as two separate components:

• Noodles: Fresh wide rice noodles, called sen yai, are browned in a pan with sweet soy sauce and set aside. Dried wide rice noodles or rice vermicelli can be used instead once they are cooked.
• Protein: Pork is mixed with salt, pepper, crushed garlic and egg before cooking. Chicken or seafood can replace it.
• Gravy base: The pork is cooked in boiling water. Carrots go in first, then baby corn.
• Thickening: Cornstarch is mixed with water separately, then stirred into the pot. Nart uses 3 tablespoons of cornstarch with 2 tablespoons of water for a gravy that starts with 3 cups of water.
• Seasoning and greens: The gravy is seasoned with fermented soybean paste, fish sauce and sugar, then finished with collard greens cooked just until wilted.
• Serving: Noodles and gravy stay separate until portioning, when the gravy is ladled over each plate of noodles.

Keeping the two parts separate until serving is what makes rad na different from a stir-fry. The noodles get their color and soy flavor on their own, and the gravy is added only when the dish is plated.

Choosing at a Thai restaurant

Illustrative example: you see both rad na and pad see ew on a menu and want something comforting and saucy. Choose rad na. If you would rather have chewy, slightly charred noodles without a pool of sauce, choose pad see ew. Then compare the protein and vegetables each dish lists, because those vary from kitchen to kitchen more than the cooking method does.
