Delicious Flat Iron Steak Fajitas: A Quick and Flavorful Sheet Pan Recipe

When it comes to cooking fajitas, many people immediately think of skirt steak. However, flat iron steak is a fantastic alternative that offers a flavorful and tender option for this classic TexMex dish. In fact, with its beautiful marbling and ability to cook quickly under high heat, flat iron steak is the perfect cut for a quick and delicious sheet pan fajita recipe.

To start, preheat your oven to 400°F (200°C). Meanwhile, slice your flat iron steak into thin strips against the grain. In a small bowl, whisk together the juice of one lemon and lime, minced garlic, cumin, chili powder, salt, and pepper. Pour this marinade over the steak, making sure it's fully coated.

Next, toss sliced peppers (any color you like) and onions onto a sheet pan, along with the marinated flat iron steak. Drizzle with olive oil and season with salt and pepper to taste. Spread everything out in a single layer to ensure even cooking.

Pop the sheet pan into your preheated oven and roast for 15-20 minutes or until the steak is cooked to your desired level of doneness. You can use a thermometer to check for internal temperatures between 130°F (54°C) and 135°F (57°C).

Once the steak is done, remove it from the oven and let it rest for a few minutes before slicing it thinly against the grain. Serve with the roasted peppers and onions, along with your favorite fajita toppings such as warm flour tortillas, diced avocado, sour cream, or salsa.

This sheet pan recipe is a game-changer for fajitas, offering minimal effort and maximum flavor. The tangy citrus and rich olive oil in the marinade meld beautifully with the sweetness of the peppers and onions, while the cumin and chili powder add a welcome depth of spice. So next time you're craving fajitas, give this flat iron steak recipe a try – your taste buds will thank you!
