Everything you need to know about cooking beef fillet
Beef fillet is the most tender and prized cut on the animal. It demands precision — but master the technique and the results are extraordinary.
Sear first, oven second
Get a heavy-based or cast iron pan screaming hot before the fillet touches it. Sear every surface for 2–3 minutes until a deep mahogany crust forms all over. Then transfer immediately to a 200°C oven to finish. This two-stage approach delivers a perfect crust with an evenly pink centre.
Pan then 200°C ovenA thermometer is essential
Fillet is expensive — guessing doneness is a costly mistake. Insert a digital probe into the thickest centre of the fillet. Remove from the oven 3–4°C below your target temperature; it will continue to rise during resting. For medium-rare, pull at 50°C and rest to 55°C.
Pull 3–4°C earlyButter baste for flavour
After searing, add a generous knob of butter, a few thyme sprigs, and a crushed garlic clove to the pan. Tilt the pan and continuously spoon the foaming, herb-infused butter over the fillet for 60–90 seconds before it goes in the oven. This builds extraordinary flavour in the crust.
Butter + thyme + garlicSeason well in advance
Salt the fillet at least 45 minutes before cooking — ideally an hour or more. The salt draws surface moisture out, which then dissolves and reabsorbs back into the meat, seasoning it from within. Pat completely dry with paper towels before searing; any surface moisture will cause steaming, not browning.
Salt 45+ min aheadTie the fillet for even cooking
A whole fillet tapers at both ends, meaning the tail will overcook before the centre is done. Fold the thin tail under itself and tie the fillet at 3cm intervals with kitchen string to create an even cylinder. This single step is the biggest improvement you can make for a uniformly cooked result.
Tie every 3cmCarve with confidence
Use a long, sharp carving knife and slice in one clean stroke — don’t saw. Fillet has virtually no grain compared to other cuts, so direction matters less, but consistent thickness (2–3cm slices) gives each portion the same texture. Remove the string just before carving, never before resting.

Times below are for a trimmed, tied whole fillet at room temperature — 2–3 min per side pan sear, then finished in a 200°C conventional oven. Add 5–8 minutes if cooking straight from the fridge.
| Weight | Rare (48–52°C) | Medium-Rare (53–57°C) | Medium (58–63°C) | Well Done (69°C+) | Rest |
|---|---|---|---|---|---|
| 400 – 600g | 6–8 min | 8–10 min | 10–14 min | 16–20 min | 10 min |
| 600g – 1 kg | 8–12 min | 12–16 min | 16–20 min | 22–28 min | 12 min |
| 1 – 1.5 kg | 12–16 min | 16–22 min | 22–28 min | 30–38 min | 15 min |
| 1.5 – 2 kg | 16–22 min | 22–28 min | 28–36 min | 38–48 min | 18 min |
| 2 – 2.5 kg | 20–26 min | 26–34 min | 34–44 min | 46–58 min | 20 min |
Oven times only — excluding pan sear (~10 min for a whole fillet). Always verify with a meat thermometer.
How to cook the perfect beef fillet
Follow these professional techniques for a fillet that is impeccably seared outside and perfectly pink throughout — every single time.
Dry the surface completely
This is the most overlooked step. Pat the fillet bone-dry with paper towels immediately before it goes in the pan. Any surface moisture converts to steam on contact with the hot pan, lowering the temperature and causing the meat to poach rather than sear. Dryness equals the Maillard reaction — the deep, complex crust that makes fillet extraordinary.
Use the right pan & fat
A heavy cast iron or stainless steel pan retains heat far better than non-stick when the cold meat hits it. Use a high smoke-point fat — beef dripping, rapeseed oil, or clarified butter — not olive oil, which burns. Heat until you see the first wisps of smoke before the fillet goes in. Sear without moving it until it releases naturally.
Never skip the rest
Resting allows the muscle fibres that contracted during cooking to relax and reabsorb their juices evenly throughout the fillet. For a whole fillet, rest on a warm plate under loose foil for at least 15 minutes. The internal temperature will rise a further 3–5°C, so factor this into your target. Cutting early wastes the most expensive part of the process.
Make a pan sauce while it rests
The fond (caramelised juices) left in the pan after searing is pure flavour. Deglaze with a splash of red wine or brandy, add beef stock, a knob of cold butter, and reduce for 3–4 minutes. Strain through a sieve and serve alongside the fillet. This turns a great piece of meat into a restaurant-quality dish with almost no extra effort.
Cooking times you can trust
Our beef fillet cooking time calculator uses the professional two-stage method — a high-heat pan sear to develop a deep crust on all surfaces, followed by a precise oven finish at 200°C. This is how restaurant kitchens cook fillet, and it produces far more consistent results than oven-only methods.
All oven times are calibrated for a trimmed, tied fillet at room temperature, with clear adjustments for oven type, cut preparation (including Beef Wellington), and fridge-cold starting temperature. Temperature is always the final arbiter — use a probe thermometer.
