Deliciously Easy Flank Steak with Peppers, Onions and Tomatoes Recipe Is Perfect For a Weeknight-Or Any Time
I’m a big fan of sheet pan suppers. They’re quick to prep and make clean up a breeze! That’s what inspired this Flank Steak with Peppers, Onions and Tomatoes recipe. This dinner winner comes together with only 6 ingredients so, it’s easy on the cook. Best of all, it’s not only fast, it’s absolutely delicious.
Roasting is an easy, hands-off way to make veggies tender and delicious - we flavored ours with rosemary for a perfect pairing with quick-cooked steak. The trick to even more big, bold flavor? Roast in a high temperature oven. The dry heat caramelizes natural sugars for a pop of smoky deliciousness. Then cherry tomatoes burst during cooking and create a flavorful sauce that takes this dish over the top. Tune in to our video, give it a try, then let us know what you think.
