  • Total Time: 5 hours 25 minutes
  • Yield: 4 servings

Ingredients

Marinade Ingredients

  • 1 clove garlic (roughly chopped)
  • 1/4 small white onion (roughly chopped)
  • 1/4 cup vegetable oil
  • 2 tablespoons light brown sugar
  • 2 tablespoons orange juice
  • 2 tablespoons soy sauce
  • 1/2 teaspoon chili powder
  • 1/4 teaspoon ground cumin

Main Ingredient

  • 1 1/4 pounds flat iron steak
  • Flaky sea salt (for serving)

Instructions

  1. Prepare the Marinade: Place garlic, onion, vegetable oil, light brown sugar, orange juice, soy sauce, chili powder, and ground cumin in a blender. Blend until smooth, creating a heaping 3/4 cup of marinade.
  2. Marinate the Steak: Place the flat iron steak in a shallow baking dish or a zip-top bag. Pour the marinade over the steak, ensuring it is well coated. Cover and refrigerate for at least 4 hours or up to overnight, turning the steak once during this time if possible to evenly marinate.
  3. Bring Steak to Room Temperature: Remove the steak from the marinade, allowing any excess to drip off, and discard the marinade. Let the steak sit at room temperature for 30 minutes before grilling. This step ensures even cooking.
  4. Preheat the Grill: Heat your grill for direct cooking over medium-high heat. This prepares the grill for an optimal sear and flavor development.
  5. Grill the Steak: Place the steak on the grill and cook for 4 minutes. Turn the steak once halfway through this period to achieve grill marks and even cooking.
  6. Continue Cooking: Reduce the grill heat to medium and cook the steak for an additional 6 to 8 minutes or until the internal temperature reaches 130°F for medium rare. Turn occasionally to ensure even doneness.
  7. Rest and Slice: Transfer the steak to a plate and cover it lightly with foil. Allow it to rest for 5 minutes to redistribute juices, then thinly slice the steak across the grain for maximum tenderness.
  8. Serve: Garnish the sliced steak with flaky sea salt and serve immediately for the best flavor and texture.

Notes

  • Marinating the steak longer enhances the flavor and tenderness, but do not exceed 24 hours to avoid overly soft texture.
  • Bringing the steak to room temperature before grilling prevents uneven cooking.
  • Use a meat thermometer to check doneness for perfect medium rare at 130°F.
  • If you prefer different doneness levels, adjust cooking times accordingly.
  • Letting the steak rest after grilling is key to juicy meat.
