What's the Difference Between Sirloin, Ribeye and Fillet?

Standing at the meat counter with three steaks in front of you and no idea which one to pick? You're not alone. Sirloin, ribeye and fillet are the three most popular steak cuts in the UK,  but they couldn't be more different in flavour, texture and how they cook.

At Stack Butchers, we get asked this question alot: "What's actually the difference between these cuts, and which one should I buy?" So we've put together this simple guide to help you choose the right steak for your next meal, whether that's a quick weeknight dinner or a special occasion feast.

A Quick Overview

Cut	Flavour	Tenderness	Fat Content	Best For
Sirloin	Rich, beefy	Firm bite	Medium	Everyday steak night, griddle pans
Ribeye	Bold, buttery	Very tender	High (marbled)	Grilling, BBQ, steak lovers
Fillet	Mild, delicate	Extremely tender	Low	Special occasions, pan-searing

Sirloin: The All-Rounder

Sirloin comes from the back of the animal, just behind the ribs. It's a well-exercised muscle, which gives it a firm texture and a deep, beefy flavour that many steak purists consider the most "authentic" taste of beef.

• Texture: Firmer than ribeye or fillet, with a satisfying chew
• Fat: A moderate fat cap along one edge (don't trim it off — it bastes the meat as it cooks)
• Best cooking method: High heat, quick sear — griddle pan, BBQ, or grill
• Ideal for: Weeknight dinners, guests who like a "proper" steak experience without breaking the bank

Sirloin sits in the sweet spot between price and flavour, making it the most popular choice for regular steak nights.

Ribeye: The Flavour King

Cut from the rib section, ribeye is famous for its heavy marbling — those thin streaks of fat running through the meat. As the steak cooks, that fat melts and bastes the muscle from the inside out, giving ribeye its signature juicy, buttery flavour.

• Texture: Tender with a slight chew, very juicy
• Fat: High — this is what gives ribeye its rich taste
• Best cooking method: Grilling or pan-searing over high heat; the fat needs heat to render properly
• Ideal for: BBQs, steak lovers, anyone who prioritises flavour over leanness

If you want the most flavourful steak on this list, ribeye wins every time. It's a favourite among chefs and home cooks who don't mind a bit of extra fat for a lot of extra taste.

Fillet: The Luxury Cut

Fillet (also called tenderloin) comes from a muscle that does almost no work, which is why it's the most tender cut of beef you can buy. It has very little fat and connective tissue, giving it a soft, buttery texture — but a much milder flavour than sirloin or ribeye.

• Texture: Melt-in-the-mouth tender, minimal chew
• Fat: Very low — often wrapped in bacon or served with a sauce to add richness
• Best cooking method: Pan-sear in butter, or wrap in pastry for beef Wellington
• Ideal for: Date nights, celebrations, dinner parties, or anyone who prefers a softer bite

Because fillet is the smallest and most tender part of the animal, it's typically the priciest cut, but for many, the tenderness alone makes it worth the splurge.

So Which Cut Should You Choose?

• Want maximum flavour? Go for ribeye.
• Want the most tender bite? Go for fillet.
• Want a balance of taste, texture and value? Go for sirloin.

There's no wrong answer — it really comes down to what you're after. Some of our customers even buy a mix of all three for a "steak flight" night, cooking each cut the same way to compare them side by side.

Our Top Tip: Let the Cut Guide the Cook

Whichever steak you choose, the golden rule is the same: bring it to room temperature before cooking, season generously with salt, and rest it for at least 5 minutes after cooking. This lets the juices redistribute through the meat instead of spilling out onto your board.
