How to Cook British Wagyu Bistro Fillet: One Steak from a Two-Pack

For this illustrative plate, use one bistro-fillet-labelled steak of about 200g raw weight. If you have a two-steak pack, keep the second piece within its label's storage instructions. The combined pack weight is not a timing guide for one steak.

Ingredients for one plate

• 1 bistro fillet steak, nominal 200g raw weight
• 200g small potatoes, halved
• 100g green beans
• Up to 1 tsp neutral oil for the pan
• Salt and pepper to taste

The steak and vegetable amounts are a planning example, not a current-stock claim or a tested cooked yield. Check the actual pack weight, piece count and label before cooking.

Pan method

1. Check the product label. For frozen beef, thaw fully in the fridge and follow its use-by and post-defrost directions. Keep the unused steak protected and chilled under its own pack directions.
2. Cook the potatoes and beans separately before starting the steak. Inspect the steak's actual thickness and whether it is an intact piece; those facts matter more than its trade name.
3. Pat the surface dry. Heat a pan large enough for the steak to lie flat. Add no more than the measured oil if the pan needs it.
4. Sear both broad surfaces and all outside edges. Lower the heat if the surface browns before the thicker centre reaches your intended finish. Use a clean probe in the thickest part where appropriate and follow the pack's cooking directions.
5. Move to a clean plate, rest briefly, then slice across the visible grain. Serve promptly with potatoes and beans.

FSA guidance distinguishes intact beef steaks, whose exterior may be thoroughly seared while the centre remains pink, from minced, rolled or otherwise altered beef, which needs thorough cooking. If the item is not clearly an intact steak, follow the stricter product directions.

What to check before repeating it

Record actual thickness, pan heat and the centre reading rather than copying a minutes-per-side rule from another steak. A compact steak can have a thick centre even at 200g. The bistro label alone does not prove a particular muscle, tenderness or origin story. Use the actual steak thickness and the received pack instructions rather than an assumed fixed timing.
