Instructions

  1. Step 1: Heat 2 tbsp vegetable oil in a large wok or skillet over medium-high heat until shimmering. Add 14 oz extra-firm tofu cubes and stir-fry for 6-7 minutes until all sides are golden and slightly crispy. Remove tofu and set aside.
  2. Step 2: In the same wok, add 3 minced garlic cloves and 1 tbsp minced fresh ginger. Stir-fry for 30 seconds until fragrant.
  3. Step 3: Add 3 halved baby bok choy heads and 2 tbsp rinsed, roughly chopped fermented black beans. Stir-fry for 2 minutes until bok choy leaves begin to wilt.
  4. Step 4: Stir in 2 tbsp soy sauce, 1 tbsp rice vinegar, 1 tsp brown sugar, and 1/4 cup water. Cook for 2 minutes until the sauce slightly thickens and coats the bok choy.
  5. Step 5: Return the tofu to the wok along with 2 sliced green onions and 1/4 tsp red chili flakes if using. Toss gently to combine and heat through for 1 minute before serving.

Frequently asked questions

How long does Stir-Fried Tofu and Bok Choy with Black Bean Sauce take to make?

Total time is about 30 minutes (15 min prep + 15 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Stir-Fried Tofu and Bok Choy with Black Bean Sauce?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep extra-firm tofu from drying out.

Can I substitute ingredients in Stir-Fried Tofu and Bok Choy with Black Bean Sauce?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Stir-Fried Tofu and Bok Choy with Black Bean Sauce for a different number of people?

The recipe is written for 3 servings. Multiply each ingredient by (your serving target / 3). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

Is Stir-Fried Tofu and Bok Choy with Black Bean Sauce vegetarian?
