Grilled Flank Steak, Poblano Pico

The aroma of flank steak sizzling over open flame always seems to spark instant anticipation in my kitchen. I still remember the way the smoky heat from charring the poblano peppers tickled my nose and made the whole place feel like summer, even if the clouds threatened rain that day. Prepping this meal feels like being at a lively street fair, surrounded by bursts of color and robust scents. There’s a kind of casual satisfaction that comes from tucking into a juicy steak crowned with fresh, zesty pico.

Grilling this steak for friends on a sticky June evening, I misjudged how soon folks would arrive and ended up slicing the meat while my neighbor told a story about his disastrous fishing trip. Everyone ate around the counter, piling spoonfuls of fresh pico over their portions and grinning at the smoky heat. The laughs echoing off the patio practically became the seasoning. Since then, this has been my dish for last minute gatherings—no fancy apron required.

Ingredients

• Flank steak (1 1/2 lbs): Choose one with a deep red hue and little silverskin for tenderness, and blot it dry before marinating for the best sear.
• Olive oil (3 tbsp): Acts as the flavor carrier in the marinade and gives a gorgeous crust when grilled.
• Kosher salt (1 1/2 tsp): Bring out every meaty nuance; I always sprinkle a touch more right before grilling.
• Freshly ground black pepper (1 tsp): The fresh grind makes a difference—pre-ground can taste dusty and flat here.
• Ground cumin (1 tsp): Offers earthy depth and is my secret anchor for the marinade’s flavor.
• Smoked paprika (1 tsp): Infuses subtle smokiness that pairs perfectly with the char on the steak and poblanos.
• Garlic, minced (2 cloves): Quick tip: use a microplane to grate garlic for the marinade to ensure every bite is infused with its warmth.
• Lime, juiced (1): Bright acidity in both steak and pico lifts all the other flavors—microwave for 10 seconds for maximum juice.
• Poblano peppers (2): Roast until the skin blisters; they lend the pico a gentle smoky edge without overpowering heat.
• Cherry tomatoes, diced (1 cup): Sweet and juicy, these keep the pico fresh even after an hour.
• Red onion, finely diced (1/3 cup): The sharper the knife, the less you cry; soak in ice water for less bite, if you like.
• Jalapeño, seeded and minced (1): Add as much or as little as you like for customizable heat in your pico.
• Fresh cilantro, chopped (1/4 cup): Use leaves and tender stems for bright, herbal snap throughout.
• Lime juice (1): Zest the lime before juicing to add extra verve (optional, but worth it).
• Salt (1/2 tsp) and black pepper (1/4 tsp): Balances vegetables in the pico—taste as you go and tweak if the tomatoes need more lift.

Instructions

Get the grill hot:

Preheat your grill (or grill pan) to high—you should hear a satisfying sizzle when steak hits the grates.

Make the marinade:

Whisk together olive oil, salt, pepper, cumin, smoked paprika, garlic, and lime juice in a shallow bowl, then slide the flank steak in and turn to coat every inch.

Let it soak:

While the steak soaks up flavor at room temperature for 15–20 minutes, you can prep the pico ingredients or just appreciate the vivid colors in your marinade bowl.

Char the poblanos:

Toss the poblanos right over the hottest part of the grill, turning with tongs until blistered and dark all around—your nose will know when they’re ready.

Steam and peel:

Pop the hot poblanos in a bowl and cover for 5 minutes (a plate works too) to steam; rub the skins off, pull out stems and seeds, then dice the soft flesh.

Mix the pico:

Combine poblano, cherry tomatoes, red onion, jalapeño, cilantro, lime juice, salt, and pepper in a mixing bowl and toss gently, inhaling that fresh garden scent—set aside.

Grill the steak:

Lay the steak on the hot grill for 5–6 minutes per side, resisting the urge to prod it—let it build its crust and glorious grill marks.

Rest and slice:

Once off the heat, let the steak rest for 5 minutes (grilling rule number one) before slicing thinly against the grain so each piece is perfectly tender.

Serve with style:

Fan slices across a platter and spoon the bright, charred poblano pico over the top—don't forget to taste a piece straight off the board.

Pin It

The first time my brother took a bite topped with that warm, smoky pico, he gave this exaggerated chef’s kiss gesture and declared it his new grilling gold standard. That silly moment, with everyone’s fingers sticky from lime juice and tomatoes, cemented this dish as more than just a recipe—it’s a tradition whenever family is in town.

How to Handle the Poblano Peppers

I always roast the peppers until they have char spots all over and the skins split away, creating smoky depth that infuses the whole pico. Peeling can get messy, but a quick steam in a bowl covered with a plate helps loosen the skin, and running them under cold water makes the job easier without washing away the flavor oils.

Choosing the Right Steak

I’ve learned that not all flank steaks are equal: thicker pieces are juicier and forgiving on the grill, while thinner cuts cook faster and need extra attention so they don’t get tough. Ask your butcher for one around an inch thick and look for good marbling, then let it come close to room temp before grilling for even results every time.

Slicing, Serving, and Little Extras

Slicing against the grain is crucial for tenderness—don’t rush this part, or you’ll end up chewing forever. Lay out your platter with overlapping slices, drizzle any resting juices over, and heap the bright, peppery pico down the center for a color pop guests can’t resist.

• A final squeeze of lime right before serving adds lovely zing.
• Warm tortillas on the grill make instant steak tacos.
• Don’t skip letting everyone serve themselves—it turns dinner into an event.

Recipe FAQs

→ How long should I marinate the flank steak?

Marinate at room temperature for 15–20 minutes for surface flavor and quick tenderness, or up to 2 hours chilled for deeper flavor; avoid overly long marinades that can toughen the meat.

→ What’s the best way to grill poblano peppers?

Place poblano peppers over direct high heat and turn until the skin is evenly blistered and charred (about 5–7 minutes). Transfer to a covered bowl to steam, then peel off the skins before dicing.

→ How do I check the steak’s doneness?

Use an instant-read thermometer or gauge by touch: 125–130°F for medium-rare, 135°F for medium. Aim to remove from heat slightly before target and rest to carryover cook.

→ Why slice the flank steak against the grain?

Slicing against the grain shortens muscle fibers, yielding more tender bites and a better mouthfeel for this lean cut.

→ Can the poblano pico be made ahead?

Yes. Combine the charred poblano, tomatoes, onion, jalapeño, cilantro and lime up to a day ahead; refrigerate and bring to slightly chilled or room temperature before serving to preserve brightness.

→ What are good serving suggestions and pairings?

Serve sliced steak topped with the poblano pico alongside warm tortillas or rice. Pairs well with a bold red wine or a cold lager; add avocado or cotija for extra richness.
