If you are looking for a classic steakhouse meal with a healthy homemade recipe, this Grilled Flat Iron Steak is for you. A flat iron cut packs a punch when it comes to flavor and simplicity.
People get this idea that cooking homemade suppers every single night is complicated. And let’s be real, it’s so easy these days (especially if you don’t have kids) to run out and grab a quick bite after a long day in the office. The daily grind can really kill the kitchen mojo and make skipping out for a cocktail, and something pre-made can be rather tempting.
But let’s be honest; it’s pretty rare that a steak recipe comes off the line as well as any type of steak seared at home. It’s certainly not as fresh. A great cut of beef and a trusty grill will get you the best steak you’ve ever had in no time.
What is Grilled Flat Iron Steak?
Flat Iron Steak is a rectangular cut from the shoulder portion of the cattle with a strong marbling which leads to a great flavor. Flat Irons are great options for a quick dry pan sear or grill, and are perfect for sous vide flat iron to get that edge to edge medium rare center.
After cooking, rest thoroughly before slicing thin and on a bias against the grain – this is one of those cuts where slicing against the grain greatly improves the overall enjoyment. For best results, buy a prime cut from the butcher shop, or check out our favorite places to buy meat online.

Ingredients for Flat Iron Steak
This might be the simplest list of ingredients you’ve ever seen, but the flavor is unmatched.
- Flat Iron Steak
- Salt and Black Pepper
- Compound butter – we love our roasted garlic butter for this steak.
You can also season your steak with lemon juice near the end of cooking or before serving, but this step is unnecessary as the steak itself provides all the flavor you need.
How to Make Flat Iron Steak Recipe
- Preheat your grill.
- Season steak with salt and pepper.
- Once the grill is warmed up, heat your steaks the cooler side of the grill until they are about 15 degrees below your desired finished internal temperature.
- Move the steaks to the hot side of the grill, over direct heat to sear to finish the steaks, flipping and rotating as needed for an even crust.
- Remove them from the grill, wrap them in foil, and let them rest with a big dollop of compound butter on top.
- Serve with your favorite sides, and enjoy!
How to serve Flat Iron steak
Serve grilled flat iron steak in thin strips and toss it into summer salads with grilled watermelon. It’s great over pasta or vegetable noodles tossed in marinara for a keto / low-carb / whole30 compliant meal. We love it with a great aioli recipe and fries, chopped for tacos, in sandwiches, wraps, over stir-fried veggies and any where you would use beef slices.
Leftovers & Reheating
Store your steak in a resealable plastic bag or an air tight container. Be sure to remove excess air from either. Steak will keep in the fridge for about 4-5 days.
To reheat it, wrap just the few slices you need in foil and pop it in an oven preheated to 325 degrees F for 5 to 10 minutes. Leftover steak is never as good as the day it’s made but it can be used up in a variety of ways. A common favorite way to enjoy it is by heating it up in some quick and easy steak tacos or minced into scrambled eggs.
What to Serve With
Any type of steak is delicious with a side of mashed potatoes or some smoked mushrooms. If mashed potatoes aren’t your thing, try smoked baked potatoes loaded with amazing toppings. Vegetables like smoked brussels sprouts, green beans, and sweet potatoes are also amazing choices. You will also love Grilled Jalapeno Popper Fries for a little zing!
You can also serve your flat iron steaks over marinara-tossed sweet potato noodles and mushrooms!
Other great options include chimichurri sauce made in a food processor, a salad with fresh herbs and balsamic vinegar, or delicious vegetable recipes.
