How to Cook Sirloin Steak in a Frying Pan | 2026 Updated
Bring the steak to room temperature for thirty minutes, heat a heavy pan with a high smoke point oil until almost smoking, sear each side for two to four minutes depending on thickness, baste with butter, garlic and thyme for the last minute, then rest for five minutes before slicing.
How to cook sirloin steak in a frying pan is one of those questions that sounds simple until you are standing over a smoking hob, steak in hand, wondering if you have already ruined it.
Maybe you have been there before. You buy a good piece of sirloin, spend more than you meant to, and then watch it turn grey and chewy in a pan that was never quite hot enough. Or you flip it every twenty seconds out of nerves, and somehow it still comes out overcooked in the middle. It is frustrating, and it makes an expensive cut feel like a waste of money.
Here is the good news. Getting a juicy sirloin steak with a proper sear and a pink centre comes down to a handful of steps, done in the right order. No fancy equipment, no guesswork, just a method that works every single time you use it.
What Is Sirloin Steak?
Sirloin steak is a lean, tender cut taken from the back of the cow, between the ribs and the rump. It sits between fillet and ribeye in terms of price and fat content, offering a good balance of flavour and tenderness without the cost of the most prized cuts.
Where Sirloin Comes From
The sirloin section runs along the upper back of the animal. It carries moderate marbling and a thin fat cap along one edge, which bastes the meat naturally as it cooks.
Sirloin vs Ribeye vs Fillet
Sirloin has less fat than ribeye but more bite and beefy flavour than fillet. If you want a deeper comparison, our guide on ribeye steak vs sirloin UK and fillet steak vs ribeye breaks both down cut by cut.
How to Cook Sirloin Steak in a Frying Pan, Step by Step
Bring the Steak to Room Temperature
Take your sirloin steak out of the fridge thirty to forty five minutes before cooking. Pat it completely dry with kitchen paper. A cold, damp steak steams instead of searing, which stops you getting that deep brown crust.
Choose the Right Pan
A heavy, cast iron pan or a solid stainless steel pan holds heat far better than a thin non stick one. This matters enormously, since sirloin cooks fast and needs consistent heat throughout. For a full walkthrough of heat management, see our cast iron steak recipe.
Best Oil for Searing
Use a high smoke point oil, such as rapeseed or sunflower oil, rather than butter alone. Butter burns before the pan reaches searing temperature. For more detail on oil choice, our guide on the best oil for cooking steak in a pan covers this properly.
Searing Time Per Side
For a sirloin steak around two to three centimetres thick, sear for two to three minutes per side for medium rare, or three to four minutes for medium. Thicker steaks need slightly longer on each side.
Basting with Butter, Garlic and Herbs
In the final minute, add a knob of butter, a crushed garlic clove and a sprig of thyme to the pan. Tilt the pan slightly and spoon the melted butter over the steak repeatedly. This step adds flavour and helps the crust develop evenly.
Resting the Steak
Once cooked, move the sirloin steak to a warm plate and rest it for five minutes, loosely covered with foil. Skipping this step means the juices run straight out onto the board rather than staying in the meat. Our detailed guide on how long to rest a steak explains why resting time scales with thickness.
Sirloin Steak Doneness Temperatures
Knowing your target temperature removes almost all the guesswork from this process.
Rare, Medium Rare, Medium, Well Done Table
| Doneness | Internal Temperature | Texture |
|---|---|---|
| Rare | 48°C to 50°C | Soft, deep red centre |
| Medium Rare | 52°C to 54°C | Warm, pink throughout |
| Medium | 57°C to 60°C | Firm, light pink centre |
| Well Done | 68°C and above | Firm throughout, no pink |
For a closer look at the most popular doneness level, our guide on medium rare steak temp covers this in more detail.
Checking Doneness with a Thermometer
A meat thermometer inserted into the thickest part of the steak gives you a far more reliable reading than guessing by eye. Remove the steak from the heat two to three degrees below your target, since it continues cooking slightly as it rests.
The Finger Test Method
Press the fleshy pad below your thumb while your hand is relaxed, that softness matches rare. Touch your thumb to your middle finger for medium rare, and to your little finger for well done. It is not perfect, but it is a handy backup when you do not have a thermometer.
Is It Safe to Eat Sirloin Steak Rare or Pink?
UK Food Safety Guidance on Whole Cuts
Whole, intact cuts of beef such as sirloin carry any bacteria on their outer surface only, not throughout the muscle. Searing the entire outside at a high enough temperature addresses this risk, which is why sirloin steak can safely be served rare or pink in the middle. You can read more directly from the Food Standards Agency on food safety guidance for meat. This is different from mince or burgers, which should always be cooked through, since grinding mixes any surface bacteria throughout the meat.
Common Mistakes to Avoid
- Cooking straight from the fridge. A cold steak cools the pan instantly, leading to an uneven cook and a poor crust.
- Overcrowding the pan. Too many steaks at once drops the pan temperature and causes steaming rather than searing.
- Flipping too often. Constant flipping stops a proper crust forming. Turn the steak once, or twice at most.
Buying the Right Sirloin Steak
Ideal Thickness for Pan Frying
Aim for a sirloin steak at least two to three centimetres thick. Thinner cuts overcook before a decent crust can form, while thicker cuts give you more control over the final doneness.
Grass Fed vs Grain Fed, Dry Aged Options
Grass fed beef tends to be leaner with a slightly more mineral flavour, while grain fed beef often carries more marbling and a richer taste. Dry aged sirloin takes this further, concentrating flavour through controlled moisture loss. Our guide on what is dry aged steak explains the process, and this comparison of 30 day vs 50 day aged steak is worth a look if you want to go further.
What to Serve with Sirloin Steak
Simple sides let the beef do the talking. Triple cooked chips, a peppery rocket salad, or garlic mushrooms all work well alongside a sirloin steak. For more pairing ideas, see our full guide on what can I have with steak.
Quick Pan Sauce from the Drippings
Do not throw away the pan juices. Add a splash of red wine or stock to the hot pan, scrape up the browned bits, then whisk in a small knob of butter. This turns a handful of drippings into a rich, glossy sauce in under two minutes. If you want inspiration from a steakhouse favourite, our beef dripping sauce guide is a good place to start.
FAQs
How long do you cook sirloin steak in a frying pan?
Roughly two to four minutes per side, depending on thickness and how well done you want the sirloin steak.
What temperature is sirloin steak medium rare?
Medium rare sirloin sits at an internal temperature of around 52°C to 54°C, measured at the thickest part of the cut.
Do you need oil to fry sirloin steak?
Yes. A thin layer of high smoke point oil helps the pan reach searing temperature and stops the steak sticking before a crust forms.
How long should sirloin steak rest?
Around five minutes for a standard sirloin, loosely covered with foil, so the juices redistribute through the meat.
Can you cook sirloin steak from frozen?
It is possible but not ideal. A frozen sirloin steak cooks unevenly, so thawing fully in the fridge overnight gives far better, more consistent results.
Final Thoughts
How to cook sirloin steak in a frying pan really comes down to heat, timing and patience. Get the pan properly hot, respect the timings for your chosen doneness, and always let the steak rest before you cut into it. Once you have this method down, it is worth exploring other cuts too, from our guide on sirloin steak vs rump steak to the wider roundup of best steak cuts UK diners ask about most.
