  • 1-2 pound Flat Iron steak
  • 1 teaspoon ground cumin

The beauty of cooking is that there’s always room for experimentation and customization, so don’t be afraid to make this Southwest Flat Iron Steak recipe your own. Here are a few substitutions and variations you can try:

– Instead of flat iron steak, use flank steak or skirt steak. These cuts are also great for grilling and have a similar texture and flavor profile to flat iron steak.

– If brown sugar isn’t your thing, try using honey or maple syrup instead. Both will add a touch of sweetness to the recipe.

– Want to add a smoky flavor to the dish? Try using smoked paprika in the rub instead of regular paprika.

– For those who enjoy a little kick in their dishes, add some cayenne pepper or red pepper flakes to the rub mixture to make it spicier.

– If you’re short on time, marinate the steak in the rub mixture for at least 30 minutes before grilling. This is a quick and easy way to infuse the meat with flavor if you don’t have time for overnight marinating.

– Lastly, if you’re looking for a healthier alternative, swap out the Worcestershire sauce for soy sauce or coconut aminos. These ingredients are lower in sodium than Worcestershire sauce and can give the dish an umami flavor.

Remember, cooking is all about having fun in the kitchen and making the recipe your own. Don’t be afraid to make substitutions or try new things – you never know what delicious creation you might come up with!

Tips for Perfect Results

You don’t need to be an experienced BBQ chef to cook the perfect southwest flat iron steak. With a few tips and tricks, you can ensure that your steak is juicy, flavorful, and perfectly cooked every time.

One crucial tip is to tenderize the flat iron steak before cooking it. Flat iron is a lean cut of meat, which means it can be tough if not prepared correctly. To tenderize it, you can use a meat mallet or a fork to pierce small holes all over the surface of the steak. This process will help to break down the muscle fibers and make the meat more tender.

Another tip that I highly recommend is to let the steak rest after cooking. You should always let your cooked steak rest for at least five minutes before serving it. This step allows the juices to redistribute throughout the meat, giving you a more moist and flavorful final product.

When seasoning your steak for the southwest flavor, be sure to use enough of each ingredient in your rub. Ensure that each side of the steak is thoroughly coated in seasoning by pressing it firmly into the meat.

Lastly, always preheat your grill or broiler before placing your steak on it. A seared exterior is essential when cooking a flat iron steak so you must place it on hot surfaces for best results. You should also keep a close eye on the cooking time as overcooking will lead to dry and chewy meat.

By following these simple tips, you’re guaranteed to achieve perfect southwest flat iron steak every time you cook it!


As you get ready to cook this delicious Southwest Flat Iron Steak recipe, you may have a few lingering questions. In this section, I will provide answers to some of the frequently asked questions that have come up while preparing this dish. From ingredient swaps to cooking times, I’ve got you covered with all the information you need to make this steak as tasty as possible. So, let’s jump right in!

What is a good way to cook flat iron steak?

To make the perfect steak, begin by seasoning it with salt, pepper, and steak seasoning, as per your preference. Next, place the steaks in a skillet and sear them for 2-3 minutes on each side. If the steaks need more cooking time to reach the desired level of doneness, reduce the heat to low and cook for 2-5 minutes more. Once done, allow the steaks to rest on a plate while covered with foil for 5 minutes. This step ensures that the juices are evenly distributed, resulting in a flavorful and tender steak.

What is flat iron steak best used for?

When it comes to preparing a delicious steak, the flat iron cut is definitely one of the most versatile options available. This type of steak can be prepared in a variety of ways, making it perfect for dishes such as steak fajitas, stir-frys, and more. One of the great things about cooking a flat iron steak is that the intramuscular fat will cook into the meat during the cooking process, resulting in a juicy and flavorful steak that is best enjoyed when cooked to a perfect medium-rare.

Do you need to tenderize flat iron steak?

When it comes to grilling flat iron steak, it already has enough tenderness and marbling to make your taste buds dance. Many people automatically reach for a marinade when cooking all types of beef, but it’s not necessary with flat iron steak. However, it’s important to take care not to overcook this cut of meat. Finding the perfect balance is key to achieving mouthwatering results.

Is flat iron steak a good cut of beef?

Flat iron steak is well-known for its delicious, robust flavor that is deeply infused with the beef’s natural essence. While it boasts a moderate amount of marbling, it remains relatively lean due to the shoulder muscle, from which it is cut, getting good exercise. This results in a flavorful, yet sufficiently healthy steak.
