A fast, flavor-packed flat iron steak recipe with a hard sear, butter basting, and a punchy chimichurri you will spoon on everything.
If you have ever tasted asado, the famous Argentine style of grilling, you already know the secret is not just the fire and the meat. It is the sauce sitting on the table, ready for everyone to swipe, spoon, and argue about. That sauce is chimichurri, and around my kitchen it is basically the ultimate asado condiment, the thing that belongs with asado the way ketchup belongs with fries.
This version is punchy, herb-forward, and balanced: grassy parsley, a little oregano, sharp vinegar, plenty of garlic, and enough olive oil to make it silky. No blender needed. Just a knife, a bowl, and five minutes of confidence.
