3. Preparing the Beef for Stir-Fry
The secret to tender, flavorful beef is in the preparation.
Choosing the Right Cut
For the best texture, use:
- Flank steak – Lean, flavorful, and ideal for stir-frying.
- Sirloin – More tender than flank steak, cooks quickly.
- Ribeye – Rich in fat, making it super juicy.
How to Slice the Beef
- Freeze the beef for 20 minutes – This makes slicing easier.
- Cut against the grain – This ensures tenderness.
- Thin slices (¼ inch thick) – The thinner, the better for quick cooking.
Marinating the Beef
A simple marinade helps tenderize the beef and add flavor.
- Soy sauce (2 tbsp)
- Cornstarch (1 tbsp)
- Sesame oil (1 tsp)
- Garlic & ginger (1 tsp each)
Let it marinate for at least 15 minutes while you prepare the veggies.
