This Lime Marinated Flat Iron Steak has maximum flavor and is quite tender. The steak is first marinated in lime juice, olive oil, garlic, and salt, then grilled to perfection.
What is a Flat Iron Steak?
The flat iron steak comes from underneath the shoulders of the cow, and there are only four per animal. Even though it is considered a chuck cut, it is the second most tender piece of meat on the animal.
The flat iron steak is more flavorful and tender, and is a top value for your money. Cost wise, it should run about half the cost of tenderloin. If you can't find a flat iron steak (you may have to ask your butcher), a flank steak is a great second choice.
This steak is perfect for backyard barbecues or a casual dinner party with friends. Serve with some Sauteed Spinach & Onions or roasted Brussels Sprouts and Sweet Potatoes. So easy and delicious!

How to cook Flat Iron steak
This recipe shows you how to prepare a Lime Marinated Flat Iron Steak for maximum flavor. The steak is first marinated in lime juice, olive oil, garlic, and salt, then grilled to perfection.
Marinate the steak
This step can be done the night before, or up to 20 minutes prior to grilling. The flexibility here makes this steak recipe super easy for busy cooks.
- Score the top of the steak with criss cross hatch cuts about ¼" deep. This lets the marinade into the beef.
- Add the steak and the marinade ingredients into a zip seal bag and refrigerate for at least 20 minutes.
Sear & Grill the steak
- When ready to cook, remove the steak from the bag of marinade. Shake excess liquid off so the liquid does not interfere with the searing.
You can even use paper towels and dry it more. You can pat it dryer with some paper towels also.
- Place the marinated steak in a very hot cast iron grill pan, or on your outdoor grill.
- Cook each side for about 4 -5 minutes. Test for the level of rareness you prefer.

Variations
The sky is the limit when it comes to variations for your marinade. Here are a few combinations that work well together:

- Rosemary Garlic Steak - Cut some fresh rosemary and bruise it. Crush some cloves of garlic. Omit the soy sauce and ginger. Marinate your steak with the fresh rosemary and crushed garlic with some wine to replace the soy.

Equipment
This heavy duty cast iron grill skillet will sear your steak and drain any liquid away from the meat, allowing it to grill instead of saute.
Top Tips
- Press out the excess air in the zip lock bag so the meat is covered in the marinade completely. If you have sous vide or vacuum bags, even better!
- Use a skillet that allows any juice and marinade liquids to drain away from your steak. You will get a better sear this way.
- Fresh ginger gets moldy in the refrigerator quickly. Or it shrivels up and drys out. My mom taught me the BEST ginger tip ever! Buy it fresh, and cut it into 2 inch chunks. Pop it in a freezer bag and freeze it! When a recipe calls for fresh grated or minced ginger, take it out and grate or mince it frozen. You will be amazed how much easier it is to grate or mince!
