Top 5 Tips for perfect grilled sirloin steak
- Always start with room temperature beef. That way as the outside grills the meat inside will be the perfect medium-rare. If you start with cold beef, the meat has to warm up too much before it starts cooking and you’ll end up with beef that’s burnt on the outside and rare on the inside.
- Ensure that the beef is dry before grilling to ensure proper contact between the beef and the grill or pan.
- Use oil with a neutral flavor and high smoke point. You need and oil with a high smoke point because you need a very hot pan. I use sunflower oil because it doesn’t have any flavor while having a very high smoke point. You can use olive oil too, but I just think it has too much flavor.
- Use a heavy based pan that conducts heat well. A cast iron pan is perfect. You can also use a cast iron grill pan.
- Use a thermometer to make sure that your beef is done perfectly.
How do your steak?
Knowing what temperature you need to cook your steak to is the most accurate way to get it just how you like it. Yes, you can use the cheek method or the palm method (see video below), but the most accurate way is with a thermometer. And th ese are the temperatures that you should be looking for:
- Blue Rare- 115f. Seared on the outside, completely red throughout. Meat remains firm and juices are not yet flowing.
- Rare- 120f. Seared on the outside and still 75% red throughout. Once rested, the juices are flowing and the steak is tender.
- Medium rare- 126f. Seared with 50% red center. Juicy and full of flavor. (The most popular cook)
- Medium- 134f. Only 25% pink on the inside. Drier and tougher than medium rare.
- Medium well- 150f. Done throughout and very dry. (Not recommended)
- Well Done- 160f. Unless you need it this well done for health reasons, avoid well-done steaks. They’re tough and without flavor.
Now that you’re equipped with the facts about grilling the perfect steak you can serve this with a simple peppercorn sauce (with a splash of whisky) and get grilling.
