Method
Step 1: Prep & Marinate the Beef
- Freeze flank steak for 30 minutes to make slicing easier
- Slice against the grain into very thin strips (about 1/8 inch thick)
- Combine all marinade ingredients in a bowl
- Add beef slices, mix well to coat, and marinate for 2-4 hours (or overnight for best results)
Step 2: Prep Other Components
- Julienne all bell peppers into thin strips
- Mix all sauce ingredients except cornstarch slurry in a bowl
- Slice green onions diagonally
- Have your noodles and garnishes ready to go
Step 3: Cook Noodles
- Bring a large pot of water to boil
- Cook ramen noodles according to package instructions
- Drain and rinse with cold water to stop cooking
- Toss with a tiny bit of oil to prevent sticking
Step 4: Cook the Beef
- Heat wok or large skillet over high heat until smoking
- Add 1 tablespoon oil
- Cook marinated beef in 2-3 batches (30 seconds per batch)
- Remove and set aside, keeping warm
Step 5: Cook Vegetables & Sauce
- In the same wok, add remaining oil
- Stir-fry bell peppers for 2-3 minutes until crisp-tender
- Pour in sauce mixture and bring to simmer
- Add cornstarch slurry and cook until sauce thickens slightly
Step 6: Combine & Finish
- Add cooked noodles to the wok, toss to coat with sauce
- Return beef and any accumulated juices
- Toss everything together until well combined and heated through
- Add half the green onions and toss briefly
Step 7: Serve
- Divide into bowls
- Garnish with remaining green onions
- Sprinkle with toasted sesame seeds
- Serve immediately while hot, add chili oil if desired
Notes
- Cook in batches to avoid overcrowding the wok (which would steam rather than sear the meat)
- Keep ingredients moving constantly for even cooking
- Sauce should coat noodles but not be too thick
- Taste and adjust seasoning before final serve
- Reduce sodium by using low-sodium soy sauce alternatives
