How to Slice Flank Steak (Against the Grain)
This is the whole game. Flank steak has long muscle fibers. If you slice with the grain, it chews tough. If you slice across the fibers, it eats tender—especially when sliced thin.
Easy Flank Steak Meal Ideas
- Fajitas: sliced steak + peppers + onions
- Steak salad: greens + vinaigrette + thin slices
- Bowl: rice + veggies + sauce (chimichurri is perfect)
Cast Iron Cleanup After Flank Steak (Simple Method)
Soap is fine on cast iron. The key is drying completely so moisture doesn’t sit on the pan.
- Rinse warm soon after cooking (when safe).
- Light soap scrub: rub a wet brush on a tallow dish soap bar for 2–3 seconds, then scrub lightly.
- Rinse thoroughly, then dry completely and warm 30–60 seconds.
