The Quick Take
Thin cuts of steak (under 1 inch thick) like skirt, flank, or thin strip steaks require intense, direct heat (over 600°F) for a rapid 2 to 4 minutes total, building a savory crust before the inside has a chance to overcook. Thick cuts (1.5 inches or more) like a bone-in ribeye or filet mignon demand a two-zone approach: a hard sear on a grate hotter than 1,000°F to lock in flavor, followed by a gentle finish on a cooler zone (around 300°F to 400°F) to slowly reach a perfect medium-rare 130°F internal temperature without burning the exterior.
Key Facts at a Glance
| Cut Thickness | Heat Strategy | Target Temp (Med-Rare) | Rest Time |
|---|---|---|---|
| Thin (Under 1 inch) | Direct High Heat Only | Pull at 125°F | 5 minutes |
| Medium (1 to 1.5 inches) | Direct Sear, Short Finish | Pull at 125°F | 7 minutes |
| Thick (Over 1.5 inches) | Two-Zone (Sear + Indirect) | Pull at 125°F | 10 to 15 minutes |
Mastering the Heat Zones
The biggest mistake backyard cooks make is treating all beef like it is exactly the same. Fire is a tool, and you have to wield it differently depending on what is sitting on your cutting board. Thin steaks cook all the way through in the blink of an eye. If your fire is not hot enough, by the time you develop a decent crust on a thin steak, the inside is completely gray and dry.
Thick steaks present the exact opposite problem. If you leave a 2-inch ribeye over roaring flames until the center hits medium-rare, the outside will be charred to a bitter, unrecognizable crisp. You need extreme heat for the crust, and gentle heat for the center.
This is where an Arteflame grill really shines with its natural heat zones. You can drop a thick ribeye directly on the center grate for a 1,000°F sear, then immediately slide it out to the flat steel cooktop's cooler outer edges to finish roasting. Meanwhile, you can throw a thin flank steak right near the center fire for a lightning-fast sear. No dials, no moving grates—just sliding your food to the right temperature zone.
Step-by-Step Instructions
- Build your fire. Pour a little vegetable oil on three paper napkins, place them in the center of your grill, stack firewood over the napkins and light the paper. Your Arteflame will be ready to cook in about 20 minutes.
- Prep the meat. Pat all your steaks completely dry with paper towels. Moisture is the enemy of a good sear. Season generously with coarse salt and pepper.
- The Thin Steak Method (Hot and Fast). Place your thin cuts (skirt, flank) over the hottest part of the grill. Let them sizzle hard for 1.5 to 2 minutes until a deep brown crust forms. Flip once, cook for another 1 to 2 minutes, and remove immediately.
- The Thick Steak Method (Sear and Slide). Place your thick cuts directly over the blazing center fire. Sear for 2 minutes per side to build a heavy crust. Once crusted, slide the steak to the cooler outer edge of the flat steel cooktop.
- Monitor the internal temperature. Check the thick steaks frequently. Pull them off the heat when they hit 125°F for a perfect medium-rare (they will continue cooking slightly as they rest).
- Rest the meat. Let thin steaks rest for 5 minutes, and thick steaks rest for at least 10 minutes before slicing.
Pro Tip: Always slice thin cuts like skirt or flank steak strictly against the grain. Even perfectly grilled thin steaks will be incredibly chewy if you slice them parallel to the muscle fibers.
Common Mistakes to Avoid
- The "Poke Test" Delusion: Unless you have calibrated your index finger in a laboratory, poking a steak to check doneness is a great way to serve dry meat. Use a high-quality ThermoWorks instant-read thermometer to know exactly when you hit 125°F.
- Under-salting thick cuts: A 2-inch steak needs a serious shower of Diamond Crystal Kosher Salt to season it all the way through. Do not be shy; it is a big piece of meat.
- Walking away from thin steaks: Grabbing a beer while a thin skirt steak is over the center fire means you will be eating jerky when you get back. Stand your ground—it only takes three minutes.
- Skipping the rest period: Cutting into a thick steak right off the grill spills all the flavorful juices onto your cutting board instead of keeping them in the meat. Patience is a grilling virtue.
Make It Your Own
Once you have mastered the basic heat zones for thin and thick cuts, you can start having some fun with the flavor profiles and techniques.
- The Butter Baste: While your thick steak is finishing on the cooler edge of the flat cooktop, melt a knob of butter over it with some crushed garlic and thyme.
- The Spice Crust: Coat thin steaks in a robust McCormick Grill Mates rub before hitting the high heat to create a deeply flavorful, charred bark.
- The Board Sauce: Mix olive oil, fresh herbs, and garlic directly on your cutting board, then slice your rested thick steaks right into the mixture.
- The Reverse Sear: For extremely thick steaks (over 2 inches), start them on the cool outer edge to slowly bring up the internal temp, then finish with a 60-second sear over the center fire.
Frequently Asked Questions
At what thickness should I change my grilling method?
The turning point is generally 1.5 inches. Anything thinner than 1 inch should be cooked entirely over high heat to prevent overcooking the center. Steaks 1.5 inches or thicker require a two-zone method so the center can finish cooking without the outside burning.
Do I need to cover the grill for thick steaks?
On a traditional grill, you might rely on ambient trapped heat for thick cuts. On an open-fire setup like the Arteflame, you do not need one—you simply move the crusted steak to the cooler outer edge of the flat cooktop, where the gentle, conductive heat finishes roasting the meat perfectly.
How long do I rest a thin steak versus a thick steak?
Thin steaks only need about 5 minutes of resting time to let the muscle fibers relax. Thick steaks hold much more thermal mass and need 10 to 15 minutes of resting time to ensure the juices redistribute evenly before slicing.
Keep the Fire Going
Mastering the difference between a hot-and-fast thin sear and a two-zone thick roast is the moment you graduate from someone who just cooks outside to a genuine grill aficionado. Your friends will notice, your in-laws might actually compliment you, and your steaks will finally look and taste like they came from a high-end steakhouse. Keep experimenting with your heat zones, trust your thermometer, and remember that every cut of beef deserves its own strategy over the open fire.
