  3. Step 3: Add remaining 1 tbsp avocado oil to the wok, followed by ginger and garlic. Sauté for 30 seconds until fragrant.
  4. Step 4: Add bok choy stems and shiitake mushrooms, stir-frying for 3 minutes. Add bok choy leaves, tamari, and sea salt, then cook 2 more minutes until leaves wilt.

Frequently asked questions

How long does Beef Stir-Fry with Bok Choy and Shiitake Mushrooms take to make?

Total time is about 25 minutes (15 min prep + 10 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 Beef Stir-Fry with Bok Choy and Shiitake Mushrooms?

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 flank steak from drying out.

Can I substitute ingredients in Beef Stir-Fry with Bok Choy and Shiitake Mushrooms?

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 Beef Stir-Fry with Bok Choy and Shiitake Mushrooms for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). 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.

What goes well with Beef Stir-Fry with Bok Choy and Shiitake Mushrooms?

Asian whole30 like this pair well with a compliant starch (roasted sweet potato, cauliflower rice, or plantains), a crisp salad dressed with olive oil and lemon, and sliced fruit. Skip grains, legumes, dairy and added sugar — none of them are Whole30-compliant. Tap "Plan a meal with the AI" to get specific side suggestions.
