Grilled Flat Iron Steak with Tomatoes
This grilled flat iron steak is tender, juicy, and full of flavour. Marinated with garlic, olive oil, salt, and black pepper, the steak is cooked to perfection on a grill or griddle pan. Sweet tomatoes are marinated, grilled alongside, and finished with fresh parsley for a vibrant, naturally saucy accompaniment.

Optional Pairings & Sauces
Flat iron steak pairs beautifully with bold sauces. My whiskey steak sauce works wonderfully here. A classic pepper sauce will also complement this dish and will be published soon.
