How Long to Grill Steaks (The Rule of Threes Explained) - Grilling 24x7 (2024)

Over my 20 years as a chef I have cooked more steak than I can count. Ive learned the secrets to cooking the prefect steak whether it's in the backyard or on the line at a 4 star steakhouse.

If you want to make sure your steaks are grilled to perfection every time make sure to pay attention to the simple “rule of threes” as well as my other helpful tips.

How long to Grill Steaks: The Rule of Threes

For a long time I've preached the "Rule of Threes" for explaining how long to grill a steak on a charcoal grill. The method is basically "3-3-3-3." That means:

1. grill steak side 1 over direct heat for 3 minutes
2. grill steak side 2 over direct heat for 3 minutes
3. Flip steak and grill on side 1 over indirect heat for 3 minutes
4. Finally turn steak and grill on side 2 over indirect heat for 3 minutes

I've gotten a lot of positive comments about the method but I've also caused a bit of confusion. Let's re-examine the method.

How Long to Cook Steak on Grill

The rule of threes is pretty simple. This method is based on direct and then indirect grilling so I'll start here.

Direct heat grilling is when the steak is placed directly on the grates directly over top of the heat source. The dome is normally closed.

Indirect heat is grilling on the side of the grill opposite of the heat source. The dome is always closed for indirect heat grilling.

Sometimes direct heat and then indirect heat grilling is referred to as "two zone grilling." See the picture below:

When cooking with direct heat for the rule of threes the dome should be closed.

Steak Grill Time Variables:

There are a few variables that need to be considered when using the rule of threes for cooking your steak. The variables are:

1. Thickness of steak
2. Temperature of grill
3. Temperature of steak before grilling
4. Time
5. How done you like your steak

These variables are dependent on one another. For example, if the grill temperature is not hot enough, then the time needs to be increased.

If the steaks are really thick then the grilling time needs to be increased. If you want a steak rare you need to decrease the grilling time and perhaps reduce the temperature of the steak before grilling.

The steaks above are about 1 inch thick. This is perfect for the rule of threes. Beware: Most grocery stores sell steaks that are a bit smaller than 1 inch.

These came from Costco and are routinely 1 inch thick. The rule of threes is meant for 1 inch thick steaks.

What I Consider Medium Rare

Finally it is important to note that steak doneness is also an important variable. The rule of threes as I discuss is tuned to give you a medium rare steak.

Grill Temp for Steak

Temperature of the grill is the next important variable to evaluate. I find it essential to be able to use your hand to evaluate the temperature of your grill.

I use the method where you hold you hand 1 inch over the grate and start counting. The amount of seconds that pass before you need to remove your hand is the value you'll use to assess your grill temperature.

For example if you can hold your hand 1 inch over the grate (directly over the heat source) for 2-3 seconds you have a perfect high heat for grilling a steak.

If you can only hold your hand there for 1 second or less you have a way too hot high heat and I advise not cooking just yet.

Holding your hand for 3-4 seconds is about a medium heat and 4-5 seconds is a medium low-low heat.

This method works for Great for charcoal but this Method also can be used for the Best Natural Gas Grills as well. Just use the same tips and time considerations for gas or charcoal.

These are all estimates but the key here is that once you get a feel for your own grill setup you will be able to know how long YOUR hand can stay over top of YOUR heat source to grill a perfect steak.

Essentially you'll be calibrating your own temperature measurement system. The numbers that I give above are relative to MY hand over top of MY heat source.

Steaks Should be Grilled at Room Temperature

Next, the temperature of the steak before grilling will also have a huge effect on how well done the steak is. Imagine pulling a cold steak right from the fridge and tossing it on the grill.

The center of this steak will be colder and will stay colder than the exterior of the steak while you are cooking. Using a steak directly from the fridge will lead to a more undercooked steak.

I prefer to let my steaks sit at room temperature for about 30 minutes before grilling.

This lets the steak uniformly reach room temperature. Again, the choice is up to you but it will directly affect how long you will need to grill. If your steak is colder to start you will need to cook it for a bit longer.

How to adjust the Rule of Threes for Steak Grill Time

So let's put all these variables together and learn how to modify them as we need to. How does this apply to cooking a really thick steak?

Well the best example I can think of is a thick filet mignon medallion. These steaks are normally 2-3 inches thick. Will the rule of threes work? The answer is YES! But it is a "modified rule of threes."

The one rule that I think should not be altered with the rule of threes is the three minutes of direct heat on each side of the steak.

When I cook over a high heat (holding my hand for 2-3 seconds over the heat) any more than 3 minutes on each side looks too burnt to me. Three minutes is just right for nice grill marks and a good char.

If the direct heat variables are locked this means that only the indirect times can be extended.

For a 2-3 inch steak the rule of threes will be modified to 3-3-4-4 (remember, this means minutes of direct-direct-indirect-indirect cooking) or maybe even 3-3-5-5.

The extended indirect grilling time cooks the inside of the steak while not burning the surface of the steak.

How long to Grill Steak (Thin Steaks) with the Rule of Threes

Let's go through one more hypothetical grilling problem. Let's say Mrs. Grilling 24x7 finds a fantastic sale on porterhouses at the local grocery store but they are ½ inch thick steaks.

She means well and by no means will I force her to return the steaks. Leave the steaks in the fridge right up until they are ready to be grilled.

I would have a high heat (2-3 seconds of hand holding over the grate) and I would grill the steaks for 3-3-0-0. Yup, I would toss out the indirect cooking times.

I most certainly would keep the 3 minutes of direct heat for each side because the nice char would still be necessary.

However, the steak is much thinner so the cooking time will be reduced dramatically.

I hope that the above re-examination of the "rule of threes" will give you more control over your steak cooking. You can control each variable to better suite your grilling style and taste.
