What is Flatiron Steak?
Flatiron steak, also known as butler’s steak or oyster blade steak, is a cut of beef derived from the shoulder of the cow. It is named for its distinctive shape that resembles an old-fashioned flat iron.
Despite being a relatively inexpensive cut, flat iron steak is prized for its rich, beefy flavor and tender texture, often rivaling more expensive cuts. It has minimal fat and marbling, which makes it perfect for marinating and grilling. This cut has gained popularity in recent years due to its versatility and consistent quality when cooked properly.
Ingredients
- Lime Juice: Freshly squeezed lime juice is essential for this marinade, providing a tangy and citrusy flavor that tenderizes the flatiron steak while enhancing its natural richness.
- Soy Sauce: Opt for a high-quality soy sauce to add a depth of umami flavor and a touch of salinity that complements the other marinade ingredients beautifully.
- Green Onions: These will add a mild, slightly sweet onion flavor and a hint of freshness to the marinade, balancing out the acidity and saltiness.
- Minced Fresh Ginger: Fresh ginger adds a warm, zesty kick and aromatic complexity that elevates the overall flavor profile of the steak.
- Red Pepper Flakes: A pinch of red pepper flakes introduces a subtle heat, making each bite more exciting without overwhelming the palate.
- Flatiron Steak: Look for a good-quality flatiron steak. When marinated and grilled to perfection, it offers a robust, beefy flavor and tender texture.
- Vegetable Oil (for grates or grill pan): Using vegetable oil, or olive oil, helps prevent the steak from sticking to the grill, ensuring beautiful grill marks and an even cook.
- Coarse Salt and Fresh Ground Pepper, to Taste: Seasoning with coarse salt and freshly ground pepper right before grilling accentuates the meat’s natural flavors without overpowering them.

Substitutions and Additions
- Lime Juice: If you don’t have fresh limes available, you can use lemon juice as an alternative. Lemon juice will offer a similar acidity and citrus flavor, though it may be slightly less tangy.
- Soy Sauce: Tamari or coconut aminos are excellent substitutes for soy sauce, especially for those with gluten sensitivities or dietary preferences. Both options provide a rich umami taste while being gluten-free.
- Green Onions: Shallots or even finely chopped red onion can be used in place of green onions. They will impart a more robust onion flavor, adding a different layer to the marinade.
- Minced Fresh Ginger: Ground ginger can be used if fresh ginger is not available. Use about a quarter of the amount of ground ginger compared to fresh, as it is more concentrated in flavor.
- Red Pepper Flakes: For a bit of variety, you can substitute red pepper flakes with a dash of cayenne pepper for a similar heat level or use chili powder for a smokier taste.
Additions:
- Garlic: Adding minced fresh garlic or garlic powder can enhance the marinade by imparting additional depth and complexity to the steak’s flavor.
- Honey: A tablespoon of honey can be added to the marinade for a touch of sweetness that balances the lime’s acidity and the red pepper flakes’ heat.
- Sesame Oil: A small splash of sesame oil can introduce a nutty aroma and rich flavor, complementing the soy sauce and ginger.
- Fresh Herbs: Incorporating fresh herbs like cilantro or parsley into the marinade can add a burst of freshness and a vibrant herbal note to the steak.
- Pineapple Juice or Orange Juice: As an alternative to lime juice, adding pineapple or orange juice can introduce a sweet and tangy dimension, tenderizing the meat and imparting a tropical flair.
By exploring these substitutions and additions, you can tailor the recipe to your preferences and experiment with flavors, creating a unique and delicious variation of the original Grilled Lime Marinated Flatiron Steak.
Instructions
Combine the lime juice, soy sauce, green onions, ginger, and red pepper flakes in a resealable plastic bag.

Lightly score the steak in a cross-hatch manner on both sides with a sharp knife.

Add the steak to the bag and press out all the air before sealing. Place the bag in a dish to protect against leakage.

Marinate for at least 30 minutes or overnight in the refrigerator.
Heat an outdoor grill, contact grill, or indoor grill pan to medium-high. Lightly oil the pan or grill grates.

Remove the steak from the marinade and let the excess marinade drip off. Pat dry with a paper towel.
Season to taste with coarse salt and freshly ground pepper.
Place the steak on the hot grill; cover and cook, turning once until the meat has reached the desired doneness, 6-8 minutes for medium rare (depending on the thickness of the steak).

Let the steak rest for 10 minutes before slicing thin across the grain.

Recipe Tips
- Use Fresh Ingredients: Whenever possible, use fresh lime juice, ginger, and green onions to maximize the flavor of the marinade and ultimately the steak.
- Marinate Long Enough: For the best results, marinate the steak overnight. This allows the flavors to fully penetrate the meat and enhances tenderness.
- Pat Steak Dry: Ensuring the steak is dry before grilling helps in getting a good sear and prevents steaming.
- Preheat Grill: Make sure your grill or grill pan is fully preheated before adding the steak. This ensures even cooking and perfect grill marks.
- Resting Time: Allowing the steak to rest for 10 minutes after grilling keeps the juices from running out when sliced, keeping the steak moist and flavorful.
- Thin Slices: Always slice the steak thinly and against the grain. This reduces the chewiness and ensures each bite is tender.
- Adjust Heat Level: If you prefer a spicier steak, increase the amount of red pepper flakes or add a diced jalapeño to the marinade.
- Check Doneness: Use a meat thermometer to check for doneness— an internal temperature of 130°F-135°F will yield a perfect medium-rare steak.
- Grill Cleanup: To make clean-up easier, oil the grill grates with a paper towel dipped in vegetable oil before grilling.
- Extra Basting: For added flavor, consider basting the steak with some reserved marinade during the last few minutes of grilling.
Serving Suggestions
When serving the Grilled Lime Marinated Flatiron Steak, you’ll want to pair it with complementary sides that enhance its flavors. Here are some serving suggestions to create a well-rounded and delicious meal:
- Cuban Black Beans: A classic side dish that pairs beautifully with grilled steak. The creamy and savory flavors of Cuban black beans, often seasoned with garlic, cumin, and bell peppers, provide a hearty contrast to the zesty and smoky notes of the grilled steak.
- Grilled Vegetables: Seasonal vegetables like bell peppers, zucchini, and asparagus can be grilled alongside the steak for a vibrant, colourful accompaniment. They absorb the charred flavors of the grill and add a nutritious touch to your plate.
- Corn Salsa: Fresh corn salsa made with sweet corn, tomatoes, red onions, cilantro, and a squeeze of lime offers a refreshing and slightly sweet counterpoint to the tangy steak.
- Avocado Salad: A simple avocado salad with cherry tomatoes, red onions, and a light vinaigrette can add a creamy and tangy element to the meal, complementing the richness of the flatiron steak.
- Rice Pilaf: A well-seasoned rice pilaf with herbs and a hint of citrus provides a neutral base that balances the bold flavors of the marinated steak.

Storage & Reheating
To properly store any leftover Grilled Lime Marinated Flatiron Steak, follow these steps:
- Cool Down: Allow the steak to cool down to room temperature. Avoid letting it sit out for more than two hours to prevent bacterial growth.
- Airtight Container: Transfer the cooled steak to an airtight container. This will help to preserve its flavor and prevent it from drying out.
- Refrigeration: Store the container in the refrigerator. The steak can be kept refrigerated for up to 3-4 days.
You can freeze the Grilled Lime Marinated Flatiron Steak to extend its shelf life. Here’s how:
- Wrap Properly: Wrap the cooled steak tightly in aluminum foil or plastic wrap to prevent freezer burn.
- Sealable Bag: Place the wrapped steak in a sealable freezer bag. Remove as much air as possible before sealing the bag.
- Label: Label the bag with the date. The steak can be frozen for up to 2-3 months for optimal quality.
For the best results, follow these reheating instructions to enjoy your steak warm:
- Thaw: If the steak is frozen, thaw it overnight in the refrigerator.
- Oven Method: Preheat the oven to 250°F (120°C). Place the steak on a baking sheet and cover it with foil to retain moisture. Heat in the oven for about 20-30 minutes until warmed through.
- Stovetop Method: Alternatively, you can reheat the steak in a skillet over medium-low heat. Add a splash of broth or water to the skillet and cover it with a lid. Heat for about 5-7 minutes, flipping halfway through, until the steak is warmed.
- Microwave Method: Place the steak in a microwave-safe dish and cover it with a damp paper towel. Use the medium heat setting and microwave in 30-second intervals, flipping the steak each time, until it is heated through. Avoid overcooking to maintain tenderness.
By following these storage and reheating tips, you can enjoy your Grilled Lime Marinated Flatiron Steak even after its initial preparation, keeping it as flavorful and tender as when it was first made.
Recipe FAQ
Can I use different cuts of beef for this recipe?
Yes, you can use other cuts of steak, such as flank steak, skirt steak, or ribeye, for this recipe. Keep in mind that different cuts may require adjusted cooking times to achieve your desired level of doneness.
What if I don’t have a grill?
If you don’t have a grill, you can use a grill pan or a cast-iron skillet on your stovetop to cook the steak. Preheat the pan over medium-high heat and cook the steak, ensuring you get a good sear on both sides.
Can I make the marinade ahead of time?
Absolutely! You can prepare the marinade up to 2-3 days in advance and store it in an airtight container in the refrigerator. When you’re ready to marinate the steak, just pour the marinade over the meat and follow the recipe as usual.
Can I use dried herbs instead of fresh herbs in the marinade?
Yes, you can substitute dried herbs for fresh herbs in the marinade. Since dried herbs are more concentrated, use about one-third of the amount specified for fresh herbs. For example, if the recipe calls for 1 tablespoon of fresh herbs, use 1 teaspoon of dried herbs.
What should I do if the steak is too tough?
If your steak turns out tougher than expected, you can try slicing it thinner against the grain to make it more tender. Also, consider marinating the steak for a longer period next time to further break down the muscle fibers and enhance tenderness.
