how long to grill flank steak
Grilling flank steak to juicy perfection typically takes 8-12 minutes total over medium-high heat, depending on thickness and desired doneness. Aim for an internal temperature of 130-135°F for medium-rare, with a rest afterward for best tenderness.
Grilling Basics
Flank steak is a lean, flavorful cut that benefits from high-heat searing to develop a crust while staying tender. Preheat your gas or charcoal grill to 400-450°F for optimal results—too low, and it toughens; too high risks charring the outside before the center cooks. Always pat the steak dry, season generously with salt and pepper (or a marinade for extra flavor), and oil the grates to prevent sticking.
Step-by-Step Timing
Follow these times for a 1-1.5 lb flank steak (about 3/4-inch thick), flipping once halfway:
- Sear first : Grill over direct high heat for 1-2 minutes per side to create grill marks.
- Finish cooking : Move to medium heat (or reduce gas to medium) and grill 3-5 more minutes per side, rotating occasionally for even cooking.
- Check doneness : Use a meat thermometer—pull at 125°F (it rises to 130°F while resting). Total: 9-12 minutes for medium-rare.
- Rest : Tent with foil for 5-10 minutes; this redistributes juices.
Doneness| Internal Temp (Post-Rest)| Total Grill Time
---|---|---
Rare| 125°F| 6-8 minutes
Medium-Rare| 135°F| 9-12 minutes
Medium| 145°F| 12-15 minutes
Pro Tips for Tenderness
- Slice against the grain : Look for the long muscle fibers and cut perpendicular at a 45° angle into thin strips—this transforms chewy flank into melt-in-your-mouth bites.
- Marinate if possible : Acidic mixes (soy, lime, garlic) for 2-24 hours tenderize without over-softening.
- Thickness matters : Thinner steaks (under 3/4-inch) cook in 6-8 minutes; thicker ones need 12+.
- Common pitfalls: Overcooking dries it out (flank has little fat), so err underdone and rely on the thermometer, not time alone.
Trending Twists
Recent forum chatter and recipes highlight quick marinades with trending flavors like gochujang or coffee rubs for 2026 backyard grills. One viral tip: Finish with chimichurri for herbaceous zing that pairs perfectly with summer corn salads.
TL;DR : Grill flank steak 4-6 minutes per side at 400°F+ to 130°F internal, rest 5-10 minutes, slice thin against the grain.
