Grilling a flank steak is a delicious and easy way to enjoy a flavorful meal. However, getting the temperature right can be tricky. If the temperature is too low, your steak will be undercooked and tough.
If it’s too high, you’ll end up with a burnt exterior and a raw interior. So what temperature should you grill flank steak at? Let’s find out.
Why Temperature Matters

Before we dive into the ideal grilling temperature for flank steak, let’s take a moment to understand why temperature matters when it comes to cooking meat. The internal temperature of meat determines its doneness level. Different cuts of meat require different cooking temperatures to achieve the desired doneness.
What is Flank Steak?
Flank steak is cut from the abdominal muscles of the cow. It’s a lean and flavorful cut that’s best cooked quickly over high heat. Flank steak is often used in dishes like fajitas, stir-fries, and salads.
The Ideal Grilling Temperature for Flank Steak
The ideal grilling temperature for flank steak is between 400-450°F (204-232°C). This high heat helps to sear the exterior of the steak while locking in its juices and flavor.
Pro tip: Before you start grilling, make sure your grill grates are clean and oiled to prevent sticking.
How Long Should You Grill Flank Steak?
The cooking time for flank steak depends on its thickness and desired doneness level. Here’s a rough guide:
- Rare: 4-5 minutes per side
- Medium-rare: 5-6 minutes per side
- Medium: 6-7 minutes per side
- Well-done: 8-10 minutes per side
Pro tip: To check the doneness of your steak, use a meat thermometer. Insert it into the thickest part of the steak. Here are the internal temperature ranges for each level of doneness:
- Rare: 125-130°F (52-54°C)
- Medium-rare: 130-135°F (54-57°C)
- Medium: 135-145°F (57-63°C)
- Well-done: 155°F and above (68°C and above)
Resting Your Flank Steak
Once your flank steak is cooked to your desired level of doneness, remove it from the grill and let it rest for at least 5 minutes. This allows the juices to redistribute throughout the meat, making it more tender and flavorful.
Final Thoughts:
Grilling flank steak can seem intimidating, but with these tips, you’ll be a pro in no time. Remember to preheat your grill to a high temperature, use a meat thermometer to check for doneness, and let your steak rest before slicing into it. With these simple steps, you’ll have a delicious and juicy flank steak every time!
