Ingredients Overview for Marinated Flat Iron Steak

The ingredients for the Marinated Flat Iron Steak come together to create a delicious blend of flavors and textures. Each one plays a crucial role in enhancing the taste of the steak, ensuring that every bite is satisfying and memorable. Let’s take a closer look at the key players in this dish.
- 1 pound flat iron steak: This cut is known for its tenderness and rich flavor, making it perfect for marinating. Its texture allows it to absorb the marinade beautifully, resulting in a juicy steak.
- 2 tablespoons lemon juice: Fresh lemon juice adds brightness and acidity, helping to tenderize the meat while enhancing its flavor.
- Zest of 1 lemon: The zest provides a concentrated lemon flavor that brightens the entire dish.
- 2 tablespoons balsamic vinegar: This adds sweetness and depth to the marinade, complementing the flavors of the steak.
- 2 chopped garlic cloves: Fresh garlic introduces a pungent, savory element that elevates the overall taste.
- 1 tablespoon Dijon mustard: Adds a subtle tang and creaminess to the marinade, enhancing the flavor profile.
- 1 tablespoon mayonnaise: Contributes creaminess and helps to bind the marinade ingredients, ensuring an even coating on the steak.
- Grated fresh ginger: Adds warmth and a hint of spice, creating a more complex flavor.

- 4 tablespoons olive oil: Provides richness and helps to create a silky marinade that clings to the steak.
Instructions for Marinated Flat Iron Steak

Preparing the Marinated Flat Iron Steak is a straightforward process that ensures great results. Follow these steps for a perfectly grilled steak that bursts with flavor.
- Start by cutting the flat iron steak lengthwise to form two equal strips. This helps in marinating and cooking evenly.
- In a large baking pan or Ziploc bag, combine all the marinade ingredients: lemon juice, lemon zest, balsamic vinegar, garlic, Dijon mustard, mayonnaise, ginger, fresh herbs, and olive oil. Mix them well to ensure everything is incorporated.
- Add the steak strips to the marinade, making sure they are fully coated. Cover the pan or seal the bag, and place it in the refrigerator for at least an hour to allow the flavors to penetrate the meat.
- Preheat your barbecue grill to high heat. This is crucial as you want to sear the steak and lock in the juices.
- Once the grill is hot, carefully remove the steak from the marinade and shake off any excess. It’s important to avoid having too much marinade on the steak, as this can result in flare-ups on the grill.
- Place the steak on the grill and cover it. Cook for about three minutes. This will help develop those beautiful grill marks and caramelize the marinade.
- After three minutes, turn the steaks over using tongs. Cook the other side for another three minutes or until you reach your desired doneness. For medium-rare, the internal temperature should be around 130°F.
- Once cooked to your liking, remove the steaks from the grill and let them rest for a few minutes. This resting period allows the juices to redistribute throughout the meat, ensuring a juicy bite.
- Slice the steak against the grain into thin strips. This technique ensures tenderness and enhances the overall eating experience.
- Serve the sliced steak warm with your favorite sides or toppings. Enjoy the burst of flavors from the Marinated Flat Iron Steak!
Things Worth Knowing
- Marinating Time: The longer you marinate the steak, the more flavorful it becomes. Aim for at least an hour, but overnight is even better.
- Grill Temperature: Ensure your grill is hot enough before adding the steak. A high temperature will sear the meat quickly, creating a delicious crust.
- Resting the Steak: Allowing the steak to rest post-grilling is essential for juicy results. Don’t skip this step!
- Fresh Ingredients: Using fresh herbs and citrus will enhance the flavors significantly compared to dried alternatives.

- Leftovers: Use any leftover steak in salads, sandwiches, or wraps for a quick and delicious meal.
