Beef Flank Steak

This American-style flank steak is marinated in a savoury, tangy, gently sweet and spicy mixture, then grilled and sliced thinly across the grain. It is a straightforward centrepiece for a meal, and leftovers work well in salads, wraps or sandwiches.

Marinate the steak
Refrigerate the steak for at least 2 hours and up to 12 hours.

Heat the grill
Preheat an outdoor grill or indoor grill pan to medium-high heat. For a lidded outdoor grill, the stated temperature is 450°F (232°C).

Grill the steak
Grill for 5–6 minutes per side. Check the centre with an internal thermometer: aim for 130–135°F (54–57°C) for medium-rare or about 140°F (60°C) for medium. Timing varies with the steak's thickness and the preferred doneness.

Rest and slice
Transfer the steak to a cutting board and leave it to rest for 10 minutes. Slice into thin strips across the grain, at right angles to the long fibres, or cut into ½-inch (about 1.3 cm) cubes. Drizzle with the reserved 2 tablespoons of marinade.
What is flank steak?
Flank steak is a long, lean cut from the abdominal area of the animal, valued for its robust beef flavour. This recipe uses an American-style marinade with savoury, acidic, sweet and spicy notes before quickly grilling the meat.
The marinade seasons the surface, while resting and slicing across the grain help make each piece easier to chew. The result is well suited to a simple dinner or to adding to other dishes.

Beef provides most of the protein and also contributes fat; the olive oil adds further fat, while brown sugar and the sauces contribute a smaller amount of carbohydrate. Serve a moderate portion with vegetables or salad alongside to balance the plate.
What the marinade brings
Oil and acidity: olive oil carries the seasonings, while balsamic vinegar and lemon juice bring sharpness. Soy sauce and Worcestershire add savoury depth, with mustard tying the flavours together.
Sweetness and spice: brown sugar balances the tang, and paprika, pepper and red pepper flakes give the marinade warmth. Dried herbs and powdered onion and garlic round it out.
Marinating safely
Use a sealed bag: press out excess air so the marinade can coat the steak evenly. Massage it through the outside of the bag, then keep the steak refrigerated for 2–12 hours.
Reserve first: set aside the 2 tablespoons for serving before adding the raw steak. Keep this portion separate from the meat and its used marinade.
Getting the grill ready
Heat matters: preheat the grill or grill pan to medium-high before the steak goes on. A properly heated surface helps the meat brown rather than slowly cook.
Check the centre: flank steak thickness affects timing, so use an internal thermometer rather than relying only on minutes per side. The recipe gives 130–135°F (54–57°C) for medium-rare and about 140°F (60°C) for medium.
Resting and slicing
Rest: leave the steak on a cutting board for 10 minutes after grilling. This gives the meat time to settle before it is cut.
Across the grain: look for the long fibres and slice perpendicular to them into thin strips. Cutting against those fibres is especially important for flank steak.
Serving ideas
Serve the sliced steak with mashed potatoes or a fresh fruit salad for a simple plate. A green salad or cooked vegetables also make useful accompaniments.
For another meal, add the steak to a salad, wrap, pasta dish or sandwich. Slice it shortly before serving so the pieces remain easy to portion.
Recipe notes & tips
- Use a freezer-size bag that can seal securely and hold the steak without forcing out the marinade.
- Keep the reserved marinade separate from the raw steak and its used marinade.
- Use an instant-read thermometer to check the thickest part of the steak.
- Let the steak rest for the full 10 minutes before cutting.
- Identify the direction of the fibres before slicing so you can cut across them.
- Cut into thin strips for serving, or use the recipe's option of ½-inch cubes.
Variations
- Add more heat: increase the red pepper flakes in the marinade to suit your preference.
- Use a grill pan: cook indoors on a preheated grill pan over medium-high heat.
- Serve as a salad: arrange thin steak slices over salad leaves and vegetables.
- Make wraps: tuck the sliced steak into wraps with your chosen fillings.
- Try a sandwich: layer leftover slices into bread for an easy next-day meal.
Common mistakes to avoid
- Skipping the marinade rest: the flavours have less time to coat the meat; refrigerate it for at least 2 hours.
- Leaving the steak too long: the recipe's maximum marinating time is 12 hours; remove it from the marinade by then.
- Grilling on a cool surface: the steak may not brown as intended; preheat the grill or pan first.
- Guessing doneness by time alone: thickness changes cooking time; check the centre with a thermometer.
- Cutting with the grain: long fibres can make pieces chewier; slice perpendicular to them.
- Using the used marinade to finish: it has been in contact with raw beef; use only the portion reserved beforehand.
How to store
Refrigerate leftover cooked steak in a sealed container and use within 3–4 days. Reheat gently in a pan or microwave until hot, or serve chilled in a salad or wrap.
Frequently asked questions
How long should I marinate flank steak?
Refrigerate it for at least 2 hours and no more than 12 hours, as specified in the recipe.
What temperature should the grill be?
Use medium-high heat. The recipe gives 450°F (232°C) for an outdoor grill with the lid closed.
How do I know when the steak is done?
Check the centre with an internal thermometer: 130–135°F (54–57°C) for medium-rare or about 140°F (60°C) for medium.
Why do I need to slice it across the grain?
Flank steak has long visible fibres. Cutting at right angles to them shortens the fibres and makes the slices easier to chew.
Can I cook this without an outdoor grill?
Yes. The method specifies an indoor grill pan as an alternative; preheat it to medium-high heat.
Can I use the marinade as a finishing sauce?
Use only the 2 tablespoons set aside before the raw steak is added. Do not use the marinade that has been in contact with the raw meat.
