A Hearty, Flavorful Vegetable Trio From Northeastern China

If you’re flipping through menus in Chinese restaurants, the term san xian (三鲜) can be confusing. Literally translated as “three delicacies” or “triple freshness,” it’s a flexible phrase whose meaning shifts with region and season. Originally tied to the pursuit of xiān (鲜), which can mean fresh and umami, it has countless variations. You might encounter sān xiān dumpling fillings with pork, shrimp and chives, or a vegetarian mix of egg, chives and shiitake mushrooms. There’s also shù sān xiān (树三鲜), a trio of summer fruits like loquats, mulberries and cherries, and shuǐ sān xiān (水三鲜),  referring to seasonal freshwater fish or water-grown vegetables in Jiangnan. Many of these combinations are hyper-local and seasonal. But there is one use of this phrase that means the same thing wherever you go: Dì sān xiān (地三鲜), “three delicacies from the earth,” is always a combination of potato, eggplant and bell pepper.

Interestingly, this phrase originally referred to a different trio: fava bean, amaranth and cucumber (or sometimes garlic scapes), a combination popularized in southern China. But when the combination of san xian reached the northeast, home cooks reimagined it. Lacking these types of vegetables, they turned to what they could grow locally and created a version that was hearty, satisfying and affordable. From these humble beginnings, di san xian rose to national popularity and is now one of the region’s most iconic dishes.

This combination of nightshade vegetables—potato, eggplant and green chili—appears in many culinary traditions. In Chinese cooking, you’ll find it in dishes like qīngjiāo tǔdòusī (shredded potato with green chili), and in my hometown in northeastern Sichuan, we often stir-fry green peppers with eggplant.

I first tried di san xian at a Northeastern dumpling restaurant on my university campus in Chengdu, where it was served alongside hand-made dumplings and deep-fried pork strips. The dish was deeply comforting, the vegetables’ textures transformed by deep frying: The potatoes had turned crispy outside and fluffy inside and the eggplant had developed a juicy, meaty texture that soaked up sauce. The bell peppers, fried quickly, kept their delightful crunch and bright green color. Everything was bound together by a thick, garlicky, savory glaze.

Making di san xian at home is simple, not least because these staple vegetables are widely available in most parts of the world. While restaurants specializing in Northeastern Chinese cuisine are still relatively rare here in Germany, where I live, you can easily find all of these ingredients in any local supermarket. 

Roll-Cutting the Eggplant

Long, slender Japanese and Chinese eggplants work well here, but you can also use globe eggplants. The former have thinner skin and a tender bite, while the latter is denser and meatier. Eggplants in this dish are typically cut into gǔn dāo kuài (滚刀块), or “rolling cuts.” This technique, often used for vegetables like carrots and cucumbers, creates irregular surfaces that cook more evenly and hold onto sauce. To do it, hold your knife at a 45-degree angle relative to the eggplant, slice diagonally to a 1-1½ inch piece, then roll the vegetable onto another side and cut it again at the same angle. I used Japanese eggplants here, which are thin; if you’re using a thicker Chinese eggplant, follow Chef Wang Gang’s instructions here. If you’re using globe eggplant, quarter the eggplant lengthwise, then roll cut.

Deep Fry or Pan Fry Your Di San Xian?

Deep frying gives these ingredients the soft, luscious texture you’d expect from a restaurant, but most home cooks pan fry the dish to make a “lighter” version. I’ve tested both, and the oil consumption is not vastly different (pan frying still requires about 3 tablespoons of oil). Deep frying is faster and more even; pan frying takes longer but avoids the need to handle large amounts of hot oil. Ultimately, the usage is similar, so choose whichever method feels most comfortable. The recipe below uses deep frying; if you opt to pan fry instead, you will need about 25 minutes to pan fry the ingredients and about 3 to 4 tablespoons of oil (see the tip at the bottom of the recipe).

Making the Sauce for Di San Xian

Because the vegetables are mild, this dish gets much of its flavor from a starchy and glossy sauce made from a combination of light soy sauce, dark soy sauce, sugar and, sometimes, oyster sauce. If you’re using oyster sauce (which can be omitted for a vegan option), I like to use high-quality oyster sauce to deepen the flavor and add an extra layer of umami, such as The Mala Market’s Megachef or Yangjiang Extra Pure Fujian options. Another trick, which I learned from a Chinese cooking show: Add garlic both at the start and end of cooking. The first addition infuses the sauce, while the second brightens the finish with a fresh garlicky punch.
