Kitchen Tools You’ll Need
Having everything ready before cooking makes stir-frying much easier.
You’ll need:
- Large wok or skillet
- Sharp knife
- Cutting board
- Mixing bowls
- Measuring spoons
- Tongs
- Wooden spatula
Step 1: Slice the Beef Properly
Tender beef starts with proper slicing.
Freeze the steak for about 20 minutes before cutting. This firms it up and makes thin slicing easier.
Always slice against the grain.
Aim for slices about ยผ-inch thick.
Step 2: Marinate the Beef
In a bowl combine:
- Soy sauce
- Cornstarch
- Sesame oil
- Cooking wine
Mix well with the beef.
Allow it to marinate for at least 20 minutes.
The cornstarch creates a protective coating that keeps the beef juicy during high-heat cooking.
Step 3: Prepare the Sauce
Whisk together:
- Soy sauce
- Oyster sauce
- Brown sugar
- Dark soy sauce
- Rice vinegar
- Chili garlic sauce
- Sesame oil
- Water
- Cornstarch
Set aside.
This sauce thickens beautifully once added to the hot wok.
Step 4: Toast the Szechuan Peppercorns
Heat a dry skillet over medium heat.
Toast the peppercorns for about 2 minutes until fragrant.
Grind them using:
- Mortar and pestle
- Spice grinder
Freshly ground peppercorns provide the best aroma.
Step 5: Cook the Beef
Heat one tablespoon oil until nearly smoking.
Cook the beef in small batches.
Avoid overcrowding.
Each batch only needs about:
- 1 minute per side
Remove and set aside.
The beef should remain slightly pink since it will cook more later.
Step 6: Stir-Fry the Vegetables
Add another tablespoon of oil.
Cook in this order:
- Onion
- Garlic
- Ginger
- Broccoli
- Bell peppers
Cook for around 4โ5 minutes.
The vegetables should stay slightly crisp.
Step 7: Finish the Szechuan Pepper Beef Stir-Fry
Return the beef to the wok.
Pour in the prepared sauce.
Add:
- Toasted Szechuan pepper
- Green onions
- Optional chili flakes
Stir constantly for 2โ3 minutes.
Once the sauce becomes glossy and coats everything evenly, remove from heat.
Serve immediately.
