Cut Guide

Choosing the right beef joint

Every cut has its ideal cooking method and doneness. Here’s a guide to the eight most popular beef roasting joints in the UK.

🥩

Sirloin

A premium cut from the back of the animal with a thick fat cap that bastes the meat as it roasts. Superb flavour and tenderness — ideal for special occasions.

Best: Rare–Medium
🦴

Rib of beef

The king of roasting joints. The bone conducts heat evenly and adds deep, complex flavour. A stunning centrepiece for any Sunday table.

Best: Rare–Medium
🫀

Topside

The UK’s most popular everyday roasting joint — lean, affordable, and widely available. Baste regularly and don’t overcook to keep it moist and tender.

Best: Medium
💪

Rump

Fuller in flavour than topside with a slightly firmer texture. Excellent value for money — great for a mid-week roast or when feeding a crowd.

Best: Medium
🧂

Silverside

Traditionally salted, but also excellent roasted. Very lean — add stock and vegetables to the roasting tin and keep a close eye on temperature.

Best: Medium–Well
⏳

Brisket

A tough, collagen-rich cut that becomes meltingly tender when cooked low and slow for 4–6 hours. Worth every minute — the flavour is extraordinary.

Best: Slow & low
🎯

Fillet / Tenderloin

The most tender cut — almost buttery in texture. Cooks very quickly and has little fat, so it needs careful attention to avoid overcooking. A true luxury joint.

Best: Rare
🔄

Rolled / boneless rib

All the flavour of rib roast in an easy-to-carve, boneless form. Rolled and tied for a uniform shape that cooks evenly throughout.

Best: Rare–Medium

Beef joint temperatures at a glance

Use a meat thermometer for reliable results every time. These are the recommended UK internal temperatures for beef joints.

Doneness Core temp Fan oven Conventional Mins per kg (after sear) Appearance
Rare 55–60°C 180°C 200°C / Gas 6 ~20 min/kg Deep red, very juicy
Medium rare 60–65°C 180°C 200°C / Gas 6 ~22 min/kg Pink throughout, juicy
Medium 65–70°C 180°C 200°C / Gas 6 ~25 min/kg Slight pink in centre
Well done 75–80°C 160°C 180°C / Gas 4 ~35 min/kg No pink, fully cooked
Chef’s Tips

Secrets to a perfect beef joint

Small details make a huge difference. Follow these pro tips for a roast that’s juicy, evenly cooked, and full of flavour.

🌡️

Use a meat thermometer

Timing is a guide — temperature is the truth. Every oven and joint is different. A good instant-read or probe thermometer is the single best investment you can make for roasting. Check the thickest part of the joint, away from any bone.

🧊

Rest it at room temperature

Remove your joint from the fridge 1–2 hours before cooking. A cold centre is the most common cause of uneven roasting — the outside overcooks while the middle stays underdone. Room-temperature beef cooks more predictably and evenly.

⏸️

Never skip the rest

Resting redistributes the juices throughout the meat. Tent loosely with foil for at least 20–30 minutes before carving. The internal temperature will continue to rise by 2–5°C during this time — factor this into your target temperature.

🔥

Sear first for crust & flavour

Starting at 220°C for 20 minutes triggers the Maillard reaction — creating a deep brown, flavourful crust. Then drop the temperature for the main cook. This two-stage method produces restaurant-quality results at home every time.

Beef joint cooking FAQs

How long per kg for a beef joint in the UK?
The standard UK rule is: 20 minutes per kg for rare, 25 minutes per kg for medium, and 30–35 minutes per kg for well done — after an initial 20-minute high-heat sear at 220°C. These times apply to a conventional oven at 200°C; reduce by 20°C for fan. Always add 20–30 minutes resting time after the joint comes out of the oven.
Start at 220°C (200°C fan / Gas 7) for 20 minutes to develop a brown crust. Then reduce to 200°C (180°C fan / Gas 6) for rare or medium, or 180°C (160°C fan / Gas 4) for well done. The most reliable check is internal temperature: 55–60°C for rare, 65–70°C for medium, 75–80°C for well done. Always use a meat thermometer for certainty.
Yes, but the difference is smaller than many people expect. Bone-in joints like rib of beef typically take around 10% longer per kg than boneless joints of equivalent weight, because the bone reduces heat penetration in the surrounding meat. However, the bone also conducts heat to the centre of the joint, which helps cook it evenly. Our calculator applies this adjustment automatically.
A minimum of 20 minutes for joints up to 1.5 kg, and 30 minutes for larger joints. For a large rib or sirloin over 3 kg, resting for 45 minutes is not excessive — the internal temperature will hold surprisingly well under a loose foil tent. Resting is not optional: it allows muscle fibres to relax and reabsorb the juices forced toward the surface during cooking.
Brisket requires a completely different approach to other beef joints. It’s a tough, collagen-rich cut from the chest that must be cooked low and slow (140–160°C) for 4–6 hours to break down the connective tissue into gelatin. It should be cooked in a covered dish or foil with liquid — stock, wine, or water — to keep it moist. Done correctly, it becomes meltingly tender and deeply flavoured. Our calculator detects when brisket is selected and applies slow-roast times accordingly.
Yes. Fan ovens circulate hot air much more efficiently than conventional ovens, reducing cooking time by approximately 10–15%. As a rule of thumb, reduce the temperature by 20°C compared to a conventional oven setting — so 200°C conventional becomes 180°C fan. Our calculator automatically applies the correct adjustment when you select your oven type. AGA and range cookers have their own adjustment applied too.
For most cuts — sirloin, rib, topside, rump — roast uncovered for the entire cook to allow the crust to form and colour. If the top is browning too quickly, you can loosely tent with foil for the final third of cooking. Brisket and silverside are exceptions: they benefit from being cooked covered or braised in liquid. Always rest the joint under a loose foil tent — tight wrapping steams the crust and softens it.
