Di San Xian is a beloved dish from Northern China, known for its rich flavors and satisfying textures. This stir-fry combines the earthy taste of potatoes, the creamy softness of eggplant, and the fresh crunch of green bell pepper. It's a perfect harmony of ingredients, enhanced by a savory sauce that brings everything together.
While most of the ingredients in this recipe are common, you might need to pay special attention to the eggplant. Choose a firm, glossy one without any soft spots. The soy sauce and vinegar used here are typical pantry staples, but make sure you have a good quality soy sauce for the best flavor.

Ingredients For Di San Xian Recipe
Potatoes: Peeled and cut into wedges, these provide a starchy base and a satisfying bite.
Eggplant: Cut into chunks, it adds a creamy texture and absorbs the flavors of the sauce.
Green bell pepper: Adds a fresh, crunchy element and a pop of color.
Garlic: Minced, it infuses the dish with a pungent, aromatic flavor.
Soy sauce: Adds a salty, umami depth to the stir-fry.
Vinegar: Provides a tangy contrast that balances the flavors.
Sugar: Adds a touch of sweetness to round out the savory and tangy notes.
Vegetable oil: Used for stir-frying the ingredients to a perfect golden brown.
Technique Tip for This Stir-fry
When stir-frying potatoes, make sure to cut them into uniform wedges to ensure even cooking. To achieve a golden and tender texture, avoid overcrowding the wok, which can cause the potatoes to steam rather than fry. For the eggplant, salting it before cooking can help reduce its natural bitterness and prevent it from absorbing too much oil. When adding the garlic and green bell pepper, keep the heat at medium to avoid burning the garlic, which can impart a bitter taste to the dish. Finally, when combining all the ingredients with the soy sauce, vinegar, and sugar, make sure to stir well to evenly coat the vegetables, enhancing the overall flavor profile.

- Transfer the stir-fry into an airtight container. Make sure the container is clean and dry to maintain the freshness of the dish.
- Store the container in the refrigerator if you plan to consume the dish within 3-4 days. The potatoes and eggplant will retain their texture and flavor well within this time frame.

- When ready to reheat, thaw the stir-fry in the refrigerator overnight if frozen. This gradual thawing helps maintain the texture of the vegetables.
- Reheat the dish in a wok or a large skillet over medium heat. Add a splash of vegetable oil or a bit of water to help revive the flavors and prevent sticking.

How to Reheat Leftovers
Stovetop: Heat a non-stick skillet over medium heat. Add a splash of vegetable oil to the pan. Once the oil is hot, add the leftover Di San Xian. Stir occasionally to ensure even heating. Cook for about 5-7 minutes or until the vegetables are heated through and slightly crispy.
Microwave: Place the leftover Di San Xian in a microwave-safe dish. Cover with a microwave-safe lid or damp paper towel to retain moisture. Heat on high for 2-3 minutes, stirring halfway through to ensure even heating. Check if it's hot enough; if not, continue heating in 30-second intervals.
Oven: Preheat your oven to 350°F (175°C). Spread the Di San Xian evenly on a baking sheet. Cover with aluminum foil to prevent drying out. Bake for about 10-15 minutes, stirring halfway through to ensure even heating. Remove the foil for the last 5 minutes if you prefer a slightly crispy texture.
Air Fryer: Preheat the air fryer to 350°F (175°C). Place the Di San Xian in the air fryer basket in a single layer. Heat for about 5-7 minutes, shaking the basket halfway through to ensure even heating. This method will help to retain the crispiness of the vegetables.
Steamer: Place the Di San Xian in a heatproof dish that fits inside your steamer. Bring water to a boil in the steamer pot. Place the dish in the steamer and cover. Steam for about 5-7 minutes or until heated through. This method helps to retain the moisture and flavor of the dish.
