Cook an entire dinner on one tray with this easy recipe for Sheet Pan Flank Steak with Crispy Potatoes and Broccolini! It's a simple, satisfying, and nutritious meal -- with very few dishes to wash at the end!
Personally, I've never been a huge steak lover. But I married a meat-and-potatoes lovin' guy, and then gave birth to 3 meat-and-potatoes lovin' boys. As a result, I've learned to prepare beef in a variety of ways...and this is by far one of my favorites!
I can't take full credit for the delicious flank steak, because it's actually inspired by the flank steak marinade that my mom served regularly when I was growing up.
It was the ONLY beef that I remember loving as a child, and it remains one of my favorites to this day. Something about the sweet, savory, tender, and juicy meat sliced into thin strips just makes my mouth water.
I love to serve the flank steak sliced over a big green salad with plenty of other chopped veggies when I'm looking for a light option; however, the ease of preparing this entire dinner on ONE TRAY -- complete with crispy oven-roasted potatoes and browned, charred baby broccoli -- makes it a winner in my book.
My Sheet Pan Flank Steak with Crispy Potatoes and Broccolini is a meal that makes my growing boys smile, while also transporting me back to happy childhood memories of my own!
Cooking for Just Two? You can either find a slightly smaller flank steak and cut the rest of the ingredients in half, or prepare the full recipe but freeze the leftover steak. I like to use leftover steak in tacos or French Dip sandwiches later in the week!
Want to Prep Ahead? You can marinate the meat up to 24 hours in advance, so that there's very minimal last-minute work involved!
