Step‑by‑Step Instructions for Grilled Flank Steak with Poblano Pico
Step 1: Marinate the Steak
In a bowl, whisk together olive oil, lime juice, minced garlic, ground cumin, smoked paprika, kosher salt, and black pepper until well combined. Place the flank steak into a resealable bag or shallow dish, pouring the marinade over the meat. Ensure it’s fully coated, then let it marinate for 30 minutes at room temperature for maximum flavor.
Step 2: Prepare the Poblano Pico de Gallo
While the steak marinates, char the poblano peppers on a grill or over an open flame until the skin is blistered and blackened, about 5-7 minutes. Remove the peppers and let them cool slightly before chopping, then combine them in a bowl with diced cherry tomatoes, finely diced red onion, minced jalapeño, chopped cilantro, additional lime juice, salt, and black pepper. Mix well and refrigerate until serving.
Step 3: Preheat the Grill
Preheat your grill to high heat, around 450°F to 500°F, ensuring the grates are well-oiled to prevent sticking. This high temperature will help achieve a beautifully charred exterior and perfectly cooked interior for your grilled flank steak.
Step 4: Grill the Steak
Place the marinated flank steak directly onto the hot grill. Grill it for 4-6 minutes per side, depending on the thickness, until you reach an internal temperature of 130-135°F for medium-rare, as measured with a meat thermometer. Look for a nice char and caramelization on the outside to ensure great flavor.
Step 5: Rest the Steak
After grilling, carefully remove the flank steak from the grill and transfer it to a cutting board. Loosely cover it with aluminum foil and let it rest for 5 minutes. This resting period allows the juices to redistribute, ensuring that every slice remains juicy and tender.
Step 6: Slice and Serve
Using a sharp knife, slice the rested flank steak thinly against the grain to maximize tenderness. Serve the steak on a platter alongside the vibrant charred poblano pico de gallo. This combination enhances the dish beautifully, making it perfect for a gathering or a delicious weeknight dinner.

Grilled Flank Steak with Poblano Pico de Gallo Recipe FAQs
What should I look for when selecting flank steak?
When choosing flank steak, opt for a cut with good marbling and a bright red color. The fat will help keep the steak juicy, and a fresh-looking cut will ensure it’s tender and flavorful.
How should I store leftover grilled flank steak and pico de gallo?
Store leftover grilled flank steak and pico de gallo in separate airtight containers. The steak will stay fresh for up to 3 days in the fridge, while the pico de gallo is best enjoyed within 2 days to keep its vibrant flavor and texture.
Can I freeze grilled flank steak and pico de gallo?
Absolutely! Wrap the grilled flank steak tightly in plastic wrap and then in foil to prevent freezer burn; it can be frozen for up to 3 months. For the pico de gallo, it’s best not to freeze as fresh vegetables lose their texture when thawed. Instead, prepare it fresh when serving.
What if my grilled flank steak turns out tough?
If your steak is tough, it could be due to over-marinating or not slicing against the grain. Ensure you marinate for no more than 30 minutes, and always slice thinly against the grain to enhance tenderness. If it’s already cooked, try slicing it very thinly to make it more enjoyable.
Can I substitute any ingredients for dietary restrictions?
Certainly! For a milder pico de gallo, swap poblano peppers with bell peppers, or use green onions instead of red onions if you’re sensitive to sharp flavors. Additionally, if you’re avoiding nightshades, you can create a fresh mango salsa instead!
Is this recipe suitable for pets?
While the grilled flank steak can be safe for pets in small amounts, ensure you skip the marinade and any spices. Always feed cooked, unseasoned meat to your pets in moderation, and avoid giving them the pico de gallo as it contains ingredients like onions that are harmful to dogs.
