Di San Xian (地三鲜) is a signature northern Chinese dish from the Dongbei Region (or Northeast China), where my mom’s family comes from. When I was growing up in Beijing, it was a dish we frequently served at home and ate at restaurants.
The name Di San Xian means “three treasures from the ground”, referring to the potato, eggplant, and green pepper in the dish. These are the most common vegetables in any market in northern China and they also symbolize the end of the summer harvest. It’s also called stir fried three treasures, or stir fried three delicious in some restaurants.
Like many other Northeast Chinese dishes, the cuisine emphasizes a family style presented in a rustic way that is often viewed as less elegant. However, the cooking method does turn these three plain vegetables into a feast that will have your mouth watering simply by looking at it!

Why this recipe
To cook Di San Xian in restaurant style, you will need to quickly fry all the ingredients in hot oil in the wok. It is called Guo You (过油) in Chinese, or flash fry. It literally means to walk the ingredients through the oil. This process creates a lightly crispy crust on the outside of the veggies without using any batter, while keeping the inside al-dente.
When it comes to home cooking, I try to avoid deep frying as much as possible. So I’ve developed a few tricks to create crispy veggies with less oil and an easier process. The veggies will brown beautifully with a crispy char on the surface and tender inside, just like you’d find in a restaurant.

Ingredients
This is a perfect dish for the end of summer and fall because you might be able to find those beautiful Asian eggplants in the farmer’s market or at a regular grocery store. These days I’m delighted to find more and more of them outside of Chinatown. When they are out of season, you’ll probably need to run to the Asian market to find them.

Cannot find Asian eggplant?
Although Asian eggplant generates better results, I’ve successfully cooked this dish with regular eggplant. As long as you follow the method in the recipe, your eggplant will turn out crispy.
Soak the eggplant in salt water for 15 to 20 minutes, dry it thoroughly, and then coat it with cornstarch. This is my default method for creating crispy eggplant without deep frying. The salt water will extract moisture from the eggplant, so it will not turn soggy during the cooking.

How to cut the vegetables
Slice the potato into half-moon shapes instead of cutting it into wedges, so that both sides crisp up perfectly in the pan and the pieces will cook faster.
For the eggplant, I like to cut it into irregular shapes that are about bite-size, to create more crispy edges.
Prep the ingredients
You should group the ingredients together so it’s easier to add them during the cooking. Plus it saves you some plates to clean up later.
You can use any type of potato in the dish. Russet potatoes will become a bit crispy on the outside and creamy inside. The yellow and red yukon potatoes will be a bit crispy throughout. I usually grab what happens to look best at the market.

Afterthought
After making countless stir fry dishes, I’ve found again and again that cooking in small batches creates much better results. The recipe below only yields two servings (as a main) or 4 small servings as a side. You can always double the recipe, but remember that you need to pan fry the veggies in small batches to achieve the best outcome.
To enjoy Di San Xian, serve it hot on top of steamed rice or boiled noodles. I guarantee you’ll finish a big plate of it in no time!

Di San Xian (Stir Fried Eggplant, Potato and Pepper, 地三鲜)
Ingredients
Sauce
- 1/4 cup water
- 1 tablespoon light soy sauce
- 1/2 tablespoon dark soy sauce (*Footnote 1)
- 1 tablespoon Shaoxing wine (or dry sherry)
- 1/2 tablespoon sugar
- 1/4 teaspoon salt
- 1 teaspoon cornstarch
Stir fry
- 1/2 regular eggplant or 1 large Asian eggplants (around 10 ounces / 300 grams in total) , chopped into bite size pieces (*Footnote 2)
- 2 teaspoons cornstarch
- 1/3 cup peanut oil (or vegetable oil)
- 1 small russet potato or 2 yukon potatoes (about 1/2 pound / 230 grams in total) , halved and sliced into 1/4-inch (1/2-cm) pieces
- 1 bell pepper , chopped into bite-size pieces
- 2 green onions , chopped
- 2 cloves garlic , minced
Instructions
If using regular eggplant:
- Place eggplant into a large bowl and sprinkle with 2 teaspoons of salt. Add tap water to cover and stir to dissolve the salt. Use a small plate or a lid to cover the eggplant pieces and submerge them in the water. Soak for 15 to 20 minutes.
- Drain the eggplant and dry thoroughly with a paper towel. Sprinkle with cornstarch and gently mix by hand, until the eggplant pieces are lightly coated.
For the sauce
- Combine the sauce ingredients in a small bowl. Mix well and set aside.
To cook the stir fry
- Heat a 12” pan (or a wok) with 1/3 cup oil over medium-high heat until hot. Spread the potato pieces in the pan without overlapping. Cook without moving until the bottom turns golden. Flip to cook the other side, until golden. Transfer the potatoes to a big plate.
- Your pan should still have plenty of oil. Place the eggplant in the pan and spread the pieces without overlapping. Cook the eggplant without moving it until the bottom turns golden brown. If the oil in the pan is fully absorbed by the eggplant before cooking through, add a bit more oil to the pan. Turn to medium heat if the pan starts to smoke. Flip the pieces to cook the other side until golden brown. Transfer to a plate with the potatoes.
- If your pan still has too much oil, carefully remove some of it with a folded paper towel and leave only about 1 teaspoon of oil in the pan. Add the green onion and garlic and stir a few times until fragrant.
- Add the peppers and stir a few times to mix well.
- Mix the sauce again to dissolve the cornstarch completely. Pour the sauce into the pan. Stir a few times.
- Return the eggplant and potato to the pan. Cook and stir until the sauce has thickened and evenly coated the vegetables. Transfer everything to a plate.
- Serve hot with steamed rice as a main or as a side.
Notes
- Dark soy sauce adds an appetizing dark brown color to the sauce. Regular soy sauce will work just fine but your dish will turn out lighter in color.
- Regular eggplant contains more liquid and is more difficult to crisp up. You’ll obtain better results if you use Asian eggplant.
Tastes amazing! Will make again
This is one of my favorite dishes from China, I kept talking about missing the flavors to my parents, they didn’t understand what I was talking about. Finally got around to making it today, turns out they’ve never had it before. After all the times they’ve lived and visited there. This was a very common dish that they’ve never eaten before. I’ve been sharing your website to my FB posts too, whenever I’m posting about things I’ve cooked, I tag it there when I’m using your recipes. Easy to follow, with common ingredients, and it really tastes like local restaurant fare. Thank you for your hard work.
Made this tonight for dinner and it came out great. I used a poblano chili from the garden instead of a bell pepper and it was yummy.
This was a fantastic recipe, thank you!!
I was really surprised by this recipe: it looks so ordinary. Basic Chinese brown sauce, ordinary veggies. Seemed like it would be good but nothing special.
We made it last night and it was amazingly delicious! Definitely gonna be in the rotation. And easy easy…
Delicious!
Just one note – I didn’t understand where the cornstarch gets used in the stir fry at first, as it’s in the story but not the recipe directions.
You make great recipes!
I made this last night for dinner, with white rice and Char Siu. What a meal that was!! We ordered Di San Xian at a local Chinese restaurant. It was not stir fried, but deep fried, and the egg plant was slimey and the potatoes overcooked. I had to find a recipe that would work out better and this is definitely it! The potatoes and eggplant char up nicely. The potatoes are crispy and the eggplant creamy. Cooking the bell pepper a short time, added a little extra crunch and a contrast in flavor. I’ll be making this over and over!
I made this tonight and it was absolutely delicious! The recipe was very easy to follow and we didn’t make any changes. Will definitely be making this again and again!
I made this to use up some Asian eggplant and potatoes. I didn’t have bell pepper but subbed a large mild jalapeno and leftover chard stems. The frying took a bit of time but overall meal was pretty good. The ratio of sauce to veggies was perfect. Thank you for sharing this recipe.
Thanks! I’ve been thinking about a dish like this for years after enjoying a similar dish in a restaurant. I had some eggplants and potatoes, googled, and landed here. I don’t like green peppers and couldn’t find jalapenos, so I used half an onion instead. It was great!
This turned out super delicious! I may omit the green onions until putting the potato and eggplant back in the wok
Hello! I’ve learned *so* much about cooking stir-fry in a NYC kitchen — infinite thanks 🙂 What kind of wok did you use for this recipe?
I used a Debuyer 9″ Country Chef Frying Pan , which is like a flat bottom wok. It is made with carbon steel and very solidly built, works really well on my gas stove.
Really happy to have found this Chinese vegetarian recipe! Made it with regular eggplant using the salting trick and it turned out great, instant family favourite.
So delicious, a bit time consuming but well worth the wait, I will definitely make again in the future 🙂
This was DELICIOUS!
I ordered this dish once and immediately looked for the recipe afterwards. This is now one of my most favourite comfort dishes and I have already cooked it several times. Especially the combination of the different veggies and how the sauce brings everything together is perfect, thank you for this great recipe!
2nd time cooking th8s and I will
make many, many more times including entertaining. I wouldn’t change a thing…perfection!! Thank you for sharing it Maggie
This recipe is AMAZING. <3 I made this for my family and my parents and I loved it so much. The sauce is fantastic. Me and my mom will be adding it on everything. She doesn't even like eggplant normally, but she said the sauce makes it better. If any of you are unsure about making it…DON'T! You HAVE to try this. I'll be cooking this now regularly. Thank you so much for sharing this recipe with us.
A great, easy to follow recipe. The result is superb!!!
