Of course, save some room for dessert because Grilled Peaches with Ice Cream makes a fabulous treat to follow up this steak and mushrooms dinner! Flank steak is a fantastic cut of meat that takes really well to marinades and quick grilling. The real trick to understanding this cut of meat is to know where the grain is and slice it thinly against the grain (i.e., perpendicular to the lines you see running through the flank steak). If you can master that simple skill, you are well on your way to tender, flavorful flank steak!

Grilled Steak and Mushrooms
I think every steakhouse I have ever gone to has some steak and mushroom combination on the menu. And there is a good reason for it: steak and mushrooms are a fabulous combination both in terms of flavor and textures. A properly cooked steak with tender mushrooms can melt in your mouth and leave you reaching for another bite. This grilled flank steak is delicious even without the mushrooms, if you happen to have a fungi hater in your family. But putting them together is pure magic. This recipe is very easy and doesn’t take much hands-on time at all. Aside from a marinating period for the meat, the rest of this dish could be made in under 30 minutes, making it perfect for a nice dinner after a busy day.

How to Make Grilled Flank Steak and Mushrooms
Do you have to marinate flank steak?
Flank steak by nature is a rather lean and tough piece of meat on its own. It comes from the underside of a cow so it’s very well-worked and flavorful, but marinating and grilling it is a great way to get the best taste and texture out of it. While you don’t absolutely have to marinate flank steak before cooking, it is something that I highly recommend if you want to enjoy a tender and flavorful steak. The marinade that I share in this recipe helps to tenderize the meat and add a lot of flavors that pair really well with the cooked mushrooms.
How long does it take to grill a flank steak?
Depending on the size of the cut and how done you want the steak to be before enjoying it, the time can vary. A general rule of thumb is about 5-6 minutes per side or until it reaches a minimum of 120F degrees.
120-125 degrees F is rare130-140 degrees F is medium rareand the higher the temperature the more cooked your steak will be.
Can you over marinate beef?
Yes! Marinades shouldn’t go on for much longer than recommended by the author of any recipe because overdoing it will cause the fibers to break down too much and make the meat mushy.
How to cut flank steak
When you look at a piece of meat you will notice a grain that runs in a single direction along the top and bottom pieces. You always want to cut against it, meaning that if the grain runs the longways of the steak, you cut slices going short ways, crossing right over the grains. What this does is cuts the fibers in the meat, thereby making it more tender to chew and saving your teeth (and jaw) a lot of added work! We want this flank steak to be cut into thin strips going across the grain so that every bite is as tender as possible.
