I was always intimidated about cooking flank steak. It is known for being a tougher cut of meat and to be totally honest.. cooking steak has always seemed intimidating to me!
Honestly, it’s not that hard to cook steak if you have the right tools and you pay attention!

Ingredients for Garlic Lime Flank Steak:
How to cook flank steak:
Making this flank steak is so easy. First, whisk your marinade together. Add the flank steak and marinade in a ziploc bag or bowl. Let it marinate for at least 30 minutes.
When you’re ready to grill, cook the steak for 5-6 minutes on each side.
Cooking in the oven: We don’t recommend cooking flank steak in the oven, but it can be done! If you’re going to cook the steak in the oven, turn on your broiler. Broil the steak for 6-7 minutes on each side. Similar to on the grill, use a meat thermometer to determine if the steak is cooked.
Here’s what it looks like fresh off the grill!
Tips for flank steak:
Marinating – It’s best to marinate the steak for 2-4 hours. Limes have acid in them which helps to break down the proteins in the steak and make it tender, but over-marinating the steak can lead to a funny taste/texture. It’s best to not marinate for more than 8 hours to avoid this. 2-4 hours is the perfect amount of time for marinating, but 30 minutes will work just fine!
Let the steak rest – Do not skip the step of having the steak rest! Your steak will continue to cook after you take it off the grill. Letting it rest is the best way to lock in the juices/flavor. 5-10 minutes is the perfect amount of time to let the steak rest.
Cook it hot, quickly – Because flanks teak is a tougher cut of meat, you’re going to want to cook it on high heat relatively quickly rather than low/slow. Searing it on each side and cooking for 5-6 minutes each side should give you perfectly cooked meat, but the best way to check is by using a meat thermometer.
Slice correctly – Slice flank steak against the grain (AKA the opposite way against the lines in the meat)
Substitutions for this flank steak marinade recipe:
Cilantro – Cilantro would be a great addition to this marinade if you like it!
Oil – You can use avocado or vegetable/canola oil in place of olive oil. We don’t recommend vegetable oil because it doesn’t give much flavor.
Citrus – You can use orange or lemon in place of limes
Garlic – You can use dried garlic in place of fresh garlic. For 1.5 tablespoons fresh garlic use 2 teaspoons dried garlic.
WW Points – On blue flank steak is 3 SP for 3 oz cooked or 4 oz uncooked. This recipe yields about 26 oz cooked steak. The steak comes out to 26 points, and the olive oil would be 12 points. Since you’re not consuming most of the olive oil, I only counted 1/2 the amount of points for the olive oil (26+ 6 = 32 SP total. Divided by 6 servings = 5SP per serving on blue
We cooked ours more on the medium side, but you can cook it a little less if you prefer it more rare.
