chimichurri flank steak with charred citrus

The Backstory

Chimichurri is one of those sauces that food people go crazy for, but most versions taste the same. Parsley, garlic, vinegar, oil — it's good, but it's not a revelation. The charred citrus is what makes this one mine. You throw orange and lemon halves cut-side down on a screaming hot grill until they're black and caramelized, then chop them into the herb mixture. The bitter, smoky, sweet notes from the charred peel change everything. This is the sauce that made me realize Bobby Butter could be a real thing.

Ingredients

For the Charred Citrus Chimichurri

• 1 cup flat-leaf parsley, finely chopped
• 1/2 cup fresh cilantro, finely chopped
• 1 orange, halved
• 1 lemon, halved
• 4 cloves garlic, minced
• 1/3 cup extra virgin olive oil
• 2 tablespoons red wine vinegar
• 1 teaspoon red pepper flakes
• 1 teaspoon dried oregano
• Salt and pepper to taste

For the Flank Steak

• 2 lb flank steak
• 2 tablespoons olive oil
• 1 teaspoon salt
• 1 teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon smoked paprika

For Serving

• Crispy smashed potatoes or crusty bread
• Grilled vegetables (zucchini, peppers, onions)
• Flaky sea salt for finishing

Instructions

Make the Chimichurri

1. Place the orange and lemon halves cut-side down on a screaming hot grill or cast iron pan. Let them sit for 4-5 minutes until deeply charred and almost black. You want real char here — don't be shy.
2. Let the citrus cool slightly, then finely chop the charred flesh and some of the peel. Discard any seeds.
3. In a bowl, combine the chopped charred citrus, parsley, cilantro, garlic, olive oil, red wine vinegar, red pepper flakes, and oregano. Season with salt and pepper.
4. Let it sit for at least 20 minutes. An hour is better. Overnight is best.

Cook the Steak

1. Pull the flank steak out of the fridge 30 minutes before cooking. Pat dry, rub with olive oil, and season generously with salt, pepper, garlic powder, and smoked paprika.
2. Get your grill or cast iron ripping hot. Sear the steak for 4-5 minutes per side for medium-rare. Use a meat thermometer — pull it at 130°F.
3. Rest the steak for 10 minutes on a cutting board. This is non-negotiable. If you skip this step, all the juice ends up on the board instead of in the meat.
4. Slice against the grain, thin. Spoon the chimichurri generously over every piece.

Road Dog Tips

• No grill? Char the citrus under a broiler set to high, cut side up, 4-5 minutes until blackened. Works great.
• Make extra chimichurri. It keeps in the fridge for a week and gets better each day. Put it on eggs, use it as a marinade, drizzle it on pizza.
• Cheaper cut hack: Skirt steak works just as well. Hanger steak if you can find it is even better.
• The dinner party move: Serve it on a big wooden board, family style. Steak sliced, chimichurri in a bowl, crusty bread on the side. People lose their minds.
