Ingredients
Crispy Eggplant
- 2 large eggplants
- ¾ cup cornstarch
- ½ teaspoon garlic powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
- Neutral oil for pan-frying
Sticky Black Bean Sauce
- 1 tablespoon neutral oil
- 1 small onion finely diced
- 5 garlic cloves minced
- 1- inch piece fresh ginger grated
- 2 tablespoons black bean paste
- 2 tablespoons soy sauce
- 1½ tablespoons rice vinegar
- 2 tablespoons coconut sugar or brown sugar
- ½ cup vegetable broth or water
- 1 teaspoon toasted sesame oil
Slurry
- 1 tablespoon cornstarch
- 2 tablespoons cold water
Garnish
- 3 scallions thinly sliced
- Sesame seeds
- Fresh cilantro optional
- Chili crisp or sliced chili peppers optional
Instructions
Step 1: Prepare the Eggplant
- Cut the eggplant into bite-sized wedges or thick slices.
- Place the pieces in a bowl and season lightly with salt, garlic powder, and black pepper. Toss with cornstarch until every piece is thoroughly coated.
- Shake off any excess cornstarch.
- Kitchen Technique: Make sure the eggplant is dry before coating it. Excess moisture can cause the cornstarch to become gummy instead of crisp.
Step 2: Pan-Fry Until Crispy
- Heat a generous layer of neutral oil in a large skillet over medium-high heat.
- Add the coated eggplant in a single layer, working in batches if necessary. Pan-fry until deeply golden and crunchy on all sides.
- Transfer to a wire rack or paper towel-lined plate.
- Kitchen Technique: Don't overcrowd the pan. Crowding lowers the oil temperature and causes the eggplant to steam instead of crisp.
- Set the crispy eggplant aside while you make the sauce.
Step 3: Sauté the Aromatics
- Carefully wipe out the skillet if necessary and add a little fresh oil.
- Add the onion and cook for 3–4 minutes until softened. Add the garlic and ginger and sauté for another minute until fragrant.
- Stir in the black bean paste and cook for about 30 seconds.
- Kitchen Technique: Briefly frying the black bean paste with the aromatics blooms its flavor and makes the finished sauce taste much more complex.
Step 4: Build the Sticky Sauce
- Add the soy sauce, vinegar, coconut sugar, and vegetable broth. Stir well and bring everything to a gentle simmer.
- Taste the sauce. You want a balance of salty, savory, tangy, and slightly sweet.
- Mix the cornstarch with cold water in a small bowl to make a slurry.
- Slowly pour the slurry into the simmering sauce while stirring constantly. Cook for 1–2 minutes until the sauce becomes glossy and thick.
- Kitchen Technique: Always mix cornstarch with cold water before adding it to hot liquid. This prevents lumps and gives you a smooth sauce.
Step 5: Toss & Finish
- Add the crispy eggplant to the pan and gently toss until coated in the sticky black bean sauce.
- Turn off the heat and drizzle with toasted sesame oil.
- Transfer to a serving dish and garnish generously with scallions and sesame seeds.
- Serve immediately while the eggplant is still crisp around the edges.
