Are you a fan of cooking with beer? For a while now I have been experimenting with the use of beer in my recipes. One of my favorite ways to cook with beer is when cooking on the grill. For this post I am sharing my delicious recipe for Beer Marinated Flat Iron Steak and Tomatoes as well as some information on the newest beer to join the Guinness family: Guinness® Blonde™ American Lager. 

Guinness® Blonde™ American Lager, produced in the famed American brewing city of Latrobe, Pennsylvania, combines American hops with the world-famous 125-year-old Guinness yeast and is the perfect beer to enjoy during the warm months of the summer.  Guinness® Blonde™ American Lager is a crisp, light beer and combines the finest American ingredients, blending floral and citrus notes with a unique biscuit malt flavor.  It is  a complex and flavorful lager, hoppy and citrusy on the nose from the hops uses, delivering a long malt, biscuity finish and perfectly balanced.

To make my  Beer Marinated Flat Iron Steak and Tomatoes I used Guinness® Blonde™ American Lager as both a marinade and a cooking liquid. Marinating steak is a great way to change the flavor profile of the meat and enhance the flavor while also acting as a tenderizer for tougher cuts of meat. My marinade includes beer, olive oil, soy sauce, garlic, lime juice, grill seasoning, salt, pepper and fresh cilantro. I prepared the marinade in a plastic zipper bag and allowed it to soak for 1 hour.

While the steak was marinating I began preparing the beer marinated tomatoes. I used fresh grape tomatoes and combined them, with freshly sliced garlic, in a simple liquid of beer, olive oil and salt and pepper.

 The tomatoes cooked right on the grill in a cast-iron skillet until the liquid was reduced and the tomatoes broke down to take on a stewed consistency. After the tomatoes cooked for a bit I then started to cook the steak. The steak was placed on a hot grill and grilled to a medium-well temperature.

To plate, I served the beer marinated flat-iron steak and tomatoes with arugula and feta salad, some Guinness® potato chips and a nice, cold Guinness® Blonde™ American Lager.
