I love to cook. I really do. But the majority of nights, I don’t have the time (or the energy) to put a full, elaborate meal on the table.
And I’m sure you don’t, either. And that’s probably why you are here.
I’m all about the easy recipes. Easy to put together, not a lot of exotic ingredients, and something the whole family will eat.
And this Balsamic Grilled Flank Steak checks all of those boxes.
Only a few minutes to put together the marinade, then a few minutes to grill it once it has had some time to marinate in the refrigerator. It really doesn’t get much easier than this!
How to Make It
MARINATE: Combine your balsamic vinegar, Dijon mustard, olive oil, onion powder and garlic powder in a large ziplock bag. Add the flank steak and seal the bag. Marinate the steak for 30 minutes to 2 hours. If possible, turn the steak over in the bag a few times while it is marinating.
GRILL: Check the section below for instructions on how to grill your flank steak.
SLICE: Once the steak has cooked, let it sit for 5 to 10 minutes, then slice it against the grain. Slicing it against the grain means to make your slices perpendicular to the grain of the meat. You should be able to see the grain and which direction it runs. Instead of cutting alongside that grain, cut perpendicular to it so that the bites are more tender and easier to chew through.
How to Grill Flank Steak
Because flank steak is thin, it grills up very quickly.
I like to heat the grill up to high. When the grill is hot, add the flank steak, and cook about 4-5 minutes per side, depending on how well you like your steak done. We like medium rare, so usually do about 4 minutes per side.
If you have an instant read thermometer, you’ll be able to see more accurately how well done your steak is.
Medium Rare: 135ºF
Medium Well: 155ºF
Well Done: 165ºF

What to Serve With This Balsamic Grilled Flank Steak
I usually try to keep it pretty simple when I make a simple meal like this. My go-to is to just throw some veggies on a sheet pan and roast them. This is great for cleaning out the fridge and using up what vegetables I have on hand. But here are some other side recipe ideas that would be great!
