Flank is a lean, long-fiber cut that rewards high heat and a quick finish—the intense sear caramelizes the sugars in the rub and concentrates the chili’s fruitiness while leaving the interior tender and juicy. The rub in this version is simple on purpose so the chile’s smoky, raisiny notes can take center stage without extra competing spices. The lime-chimichurri keeps the plate lively—fresh parsley and zesty lime cut through the fat and char, making slices of steak sing whether you serve them on a platter for a backyard crowd or tucked into tacos. Small timing decisions matter: heat the grill hot, monitor internal temperature rather than rely on clock time, and always slice thin across the grain to maximize tenderness. This recipe is for cooks who want bold, grill-forward flavor with minimal fuss and a bright finishing sauce that elevates every bite. ## Recipe Information - Prep Time: 20 minutes - Cook Time: 12 minutes - Total Time: 42 minutes - Servings: 6 - Difficulty: Medium - Category: Grilling ## Ingredients ### Prepare the lime-chimichurri - 1 cup Flat-leaf parsley (packed) - 3 cloves Garlic cloves - 2 tbsp Fresh lime juice ### Make the ancho rub and season the steak - 1 1/2 lb Flank steak - 2 tbsp Ancho chili powder - 1 tbsp Light brown sugar - 1 tsp Smoked paprika - 1 1/2 tsp Kosher salt - 1 tsp Freshly ground black pepper - 3 tbsp Extra-virgin olive oil (total: for rub + chimichurri) ## Ingredient Guide ### Ancho chili powder Ancho chili powder is ground dried poblano pepper, commonly used in Mexican cuisine; it has a mild heat with sweet, raisin-like and lightly smoky fruitiness. Many U.S. home cooks may not be familiar with its specific flavor profile even if they know generic chili powder. Find it at Latin markets, well-stocked supermarkets, or online; you can substitute guajillo or pasilla powder for a similar fruity-chile flavor, or mix mild chili powder with a pinch of smoked paprika for a quick stand-in. ### Smoked paprika Smoked paprika (Spanish pimentón) is made from peppers smoked over oak, giving a deep smoky, slightly sweet paprika flavor central to Spanish cooking. It’s more distinctive than regular paprika and adds both color and a pronounced smoky aroma. You can find it in most grocery stores or online; if you don’t have it, substitute sweet paprika plus a tiny pinch of chipotle powder or a drop of liquid smoke (used sparingly) to mimic the smoke. ## Instructions ### 1. Make the ancho rub and season the steak In a small bowl, combine the ancho chili powder, light brown sugar, smoked paprika, kosher salt, and freshly ground black pepper. Pat the flank steak dry with paper towels, rub both sides with about 1 tablespoon of olive oil, then press the spice mixture firmly into the meat so it forms an even coating. Let the seasoned steak sit at room temperature for 10–20 minutes (or refrigerate up to 2 hours) to allow the rub to adhere. ### 2. Prepare the lime-chimichurri Finely chop the parsley and mince the garlic, then combine in a bowl with fresh lime juice. Stir in the remaining olive oil, season with a pinch of salt and a few grinds of black pepper, and taste—add a touch more lime if you want brighter acidity. This quick chimichurri is intentionally bright and loose so it shines against the smoky crust of the steak. ### 3. Preheat and oil the grill Heat the grill to high (500–550°F / 260–290°C) with a clean grate—this searing heat creates the crust. Use a paper towel dipped in oil and tongs to oil the grates (or brush lightly with oil) so the steak releases easily and gets good grill marks. ### 4. Grill the steak over high heat Place the rubbed flank steak over direct high heat and sear for 4–6 minutes per side for medium-rare (timing varies with thickness). Move to a cooler part of the grill only if the exterior is charring too quickly; use an instant-read thermometer and pull at 125–130°F (52–54°C) for medium-rare. Let the fire char the rub—don’t press down—and flip only once or twice for a good crust. ### 5. Rest, slice across the grain, and serve Transfer the steak to a cutting board and tent loosely with foil; rest 8–10 minutes so juices redistribute. Identify the grain (muscle fibers) and slice thinly across the grain at a steep angle—about 1/4-inch slices—to maximize tenderness. Arrange slices on a platter and spoon the lime-chimichurri over the steak or serve it on the side for guests to add as they like. ## Nutrition Estimated nutrition per serving (4 oz steak): - Calories: 284 kcal - Protein: 26.1 g - Carbohydrates: 6.6 g - Fat: 17.2 g - Saturated Fat: 5 g - Trans Fat: 0 g - Fiber: 2.3 g - Sugar: 2.8 g - Added Sugars: 0 g - Cholesterol: 81 mg - Sodium: 506 mg - Potassium: 523 mg - Calcium: 56 mg - Iron: 3.2 mg - Vitamin D: 0.1 mcg ## Tips ### Pat Steak Bone-Dry Use paper towels to remove surface moisture before oiling so the rub adheres and the meat sears cleanly rather than steams. ### Press Rub Firmly After oiling, press the spice mix into the meat with your hands—this builds a compact crust that chars attractively on the grill. ### Use an Instant Thermometer Check the thickest part and pull at 125–130°F (52–54°C) for medium-rare; the steak will rise a few degrees while resting. ### Hot, Short Sear Sear over very high heat for 4–6 minutes per side depending on thickness, moving only if the rub is burning rather than browning. ### Slice Across Grain Let the steak rest 8–10 minutes, identify the direction of the muscle fibers and cut thin (about 1/4-inch) at a steep angle to shorten fibers. ## Variations and Substitutions ### Cilantro-Lime Chimichurri Swap half the parsley for cilantro and add a pinch of ground cumin for a southwestern lift that's excellent with corn-based sides. ### Chipotle-Ancho Rub Replace 1 tablespoon ancho with 1 teaspoon chipotle powder for deeper smoke and a touch of heat, then reduce brown sugar slightly to avoid over-charring. ### Skirt or Bavette Substitute If you can’t find flank, skirt or bavette steak work well; they cook faster so reduce searing time and watch temperatures closely. ### Vegetarian Cauliflower Steaks For a plant-based option, rub thick cauliflower steaks with the ancho mix and grill over high heat until charred and tender, then finish with the lime-chimichurri. ## Notes This ancho-rubbed flank steak is a great centerpiece for late-summer cookouts—charred and smoky outside with a bright herb-lime finish. Home cooks will love how quickly it comes together and the easy cross-grain slicing that makes every bite tender. ### Storage and Make-Ahead Store leftover sliced steak and chimichurri separately in airtight containers in the refrigerator for up to 3–4 days; keeping the sauce separate preserves texture and brightness. Reheat slices gently in a skillet over low heat with a splash of beef broth or oil to avoid overcooking, or enjoy cold on salads and sandwiches. Cooked steak can be frozen for up to 2 months—slice first for quicker thawing and reuse. ### Serving Suggestions Serve the sliced steak with grilled street corn, charred scallion potatoes or a black-bean-and-corn salad for late-summer brightness; add quick pickled red onions for a sweet-tangy counterpoint. For drinks, a citrus-forward margarita or a light Mexican lager complements the smoky-ancho flavors, while a mezcal spritz leans into the smoky notes. Plate the steak on a warm platter and spoon chimichurri over just before serving so it stays vivid. ## Frequently Asked Questions ### Can I make the rub ahead of time? Yes—mix the ancho, smoked paprika, brown sugar, salt and pepper and store in an airtight jar for several weeks; press freshly for best aromatic impact when you season the day of grilling. ### What if I don’t have an instant-read thermometer? You can use the finger test to estimate doneness or cut into the thickest part to check color, but these are less reliable—an instant thermometer is the safest way to hit medium-rare with flank. ### My rub is charring too fast—what should I do? Move the steak to a cooler zone of the grill or reduce heat and cook with the lid closed; reduce searing time next time or use slightly less brown sugar to prevent rapid caramelization. ### Can I prepare the chimichurri ahead? Yes—the chimichurri can be made several hours ahead to let flavors meld, but add a splash more lime just before serving if it has dulled. ### How thin should I slice the steak for tacos? For tacos slice about 1/8–1/4 inch thin across the grain; thinner slices are easier to fold in tortillas and keep each bite tender. ## Related Recipes and Guides - [Tandoori Yogurt Marinated Grilled Chicken (Tandoori Style on the Grill)](https://www.topshelf.recipes/recipes/tandoori-yogurt-marinated-grilled-chicken) - [Labor Day Grilled Lobster Rolls with Charred Scallion Brown Butter & Lemon‑Herb Aioli](https://www.topshelf.recipes/recipes/labour-day-grilled-lobster-rolls-charred-scallion-brown-butter-lemon-herb-aioli) - [Bulgogi Smash Burger](https://www.topshelf.recipes/recipes/bulgogi-smash-burger) - [Campfire‑Smoked Potato Salad with Mustard‑Bacon Vinaigrette — A Labor Day Grilling Side for Steak](https://www.topshelf.recipes/recipes/campfire-smoked-potato-salad-mustard-bacon-vinaigrette) - [Hanger Steak with Shallot Sauce](https://www.topshelf.recipes/recipes/hanger-steak-with-shallot-sauce) - [Grilled Pineapple Upside-Down Cake](https://www.topshelf.recipes/recipes/grilled-pineapple-upside-down-cake) - [Lean Labor Day Grilling Menu](https://www.topshelf.recipes/articles/lean-labor-day-grilling-menu) - [Weeknight Grill Roundup: 18 Recipes Under 30](https://www.topshelf.recipes/articles/weeknight-grill-roundup-18-under-30) - [Gluten-Free Weeknight Grilling Plan](https://www.topshelf.recipes/articles/gluten-free-weeknight-grilling-plan)
