How to grill steak
When it comes time to grill your steak – you have to be very careful or you can overcook it very quickly. General rule of thumb is to oil and season and then grill them for a few minutes on each side until you are happy with the results.
The exact specifics depend on if you’re using a grill, a stovetop, and how you like yours to taste.
How to cook steak on the grill
If you are specifically grilling steak on the grill and not your stovetop…first set the grill temp for steak to 450-500 degrees and brush your steaks with oil and lightly season with salt and pepper while you wait.
Then, place the steaks on the grill until golden brown and flip over to the other side until it is grilled to perfection.
How to grill the perfect steak
Want a few grilling steak tips for the best way to grill steak? Well the most important part of the perfect steak is to find the best steak for grilling – we find these to be boneless cuts such as ribeye, strip steak, top sirloin, or even flank (these are great for fajitas and lettuce wraps). They grill up great and are delicious for lunches as leftovers!
Another tip for the best way to grill steak is to first let it sit out at room temperature for at least 20 minutes – you NEVER want to throw a cold steak straight on the grill.
Once done grilling, transfer it to a cutting board and tent with foil for about 5 minutes before serving. By doing it this way, you will come out with a perfectly grilled steak every time. And you’ll have perfect leftovers for lunch the next day!
How long to grill steak
How long you grill your steak really depends how you your steak grilled. I personally am a medium rare girl! I love a juicy steak as long as it isn’t still mooing at me 😉
Typically, however… you’ll place your steaks on the grill until golden brown for about 4-5 minutes and then flip for another 3-5 minutes, for as long as 8-10 minutes.

Now what do you do with the leftover steak the next day? We personally love a good leftover steak recipe – they are pretty good! In general we will take leftover steak and repurpose them into other meals. Sometimes it’s lunch, sometimes dinner – sometimes we even throw it into our breakfast haha!
We generally don’t try to just “reheat” it as that can be tricky, though.
