Coffee-Rubbed Grilled Flank Steak with Chimichurri
A bold, budget-friendly grilled flank steak finished with a fragrant, bright chimichurri. The coffee-sugar rub builds deep, slightly smoky crust while the herb sauce adds vibrant acidity and freshness for a well-balanced weeknight or weekend grill centerpiece.
About This Recipe
Coffee and chimichurri might sound like an unlikely pairing, but this flank-steak recipe proves they’re a perfect counterpoint: the finely ground coffee and brown sugar build a deeply caramelized, slightly smoky crust while smoked paprika ties the rub to the grill’s char. Flank is a lean, economical cut with a long grain and a real beefy bite, so the rub’s umami and the chimichurri’s acid-bright parsley and red wine vinegar keep every bite lively rather than heavy. The result is a steak that’s texturally interesting — crisp exterior, tender interior — with a savory depth that punches above its price point.
This version leans on technique over fuss. Pressing a paste-like rub into the meat and letting it rest allows flavors to adhere without needing a long marinade, while an accurate thermometer and a patient 8–10 minute rest preserve juiciness. Make the chimichurri while the steak rests — it wakes up the palate and can be made an hour or two ahead for even more rounded flavor. It’s the kind of dish that reads like special-occasion grilling but slots easily into a weeknight rotation for cooks who want bold flavor without babysitting the stove.
Ingredients for Coffee-Rubbed Grilled Flank Steak with Chimichurri
- 2 tbsp finely ground coffee
- 1 tbsp light brown sugar
- 1 tsp smoked paprika
- 1 1/2 tsp kosher salt
- 1 tsp freshly ground black pepper
- 2 tbsp extra-virgin olive oil
- 1 1/2 lb flank steak
- 1 cup flat-leaf parsley (packed)
- 3 cloves garlic cloves
- 2 tbsp red wine vinegar
How to Make Coffee-Rubbed Grilled Flank Steak with Chimichurri
Step 1: Make the coffee rub and season the steak
In a small bowl combine the ground coffee, brown sugar, smoked paprika, kosher salt and black pepper. Add 1 tablespoon of the olive oil and stir to form a paste; rub the mixture evenly over both sides of the flank steak, pressing it into the meat. Let the seasoned steak rest at room temperature 20–30 minutes (or refrigerate, covered, up to overnight) so the rub adheres and flavors penetrate.For this step
- 2 tbspfinely ground coffee
- 1 tbsplight brown sugar
- 1 tspsmoked paprika
- 1 1/2 tspkosher salt
- 1 tspfreshly ground black pepper
- 1 1/2 lbflank steak
Step 2: Prepare the chimichurri
While the steak rests, finely chop the parsley and mince the garlic, or pulse briefly in a food processor for a looser sauce. In a bowl combine the parsley, garlic and red wine vinegar, then whisk in the remaining 1 tablespoon olive oil and a pinch of salt and freshly ground black pepper to taste. Taste and adjust acidity or oiliness; chimichurri should be bright and slightly tangy to cut the richness of the beef.For this step
- 1 cupflat-leaf parsley (packed)
- 3 clovesgarlic cloves
- 2 tbspred wine vinegar
Step 3: Grill the steak
Preheat a grill to medium-high (about 475–500°F / 245–260°C) and oil the grates. Sear the flank steak 4–6 minutes per side with the lid down for medium-rare (internal temperature 125–130°F / 52–54°C), or longer for desired doneness; use an instant-read thermometer for accuracy. For crosshatch grill marks, rotate the steak 45° halfway through each side’s cook time.Step 4: Rest, slice and serve with chimichurri
Transfer the steak to a cutting board and tent loosely with foil; rest 8–10 minutes so juices redistribute. Slice thinly across the grain into 1/4-inch slices and arrange on a platter, spooning chimichurri over the top or serving it on the side. Serve warm with extra chimichurri for guests to add as desired.

Coffee-Rubbed Grilled Flank Steak with Chimichurri Tips
Use very fine coffee
Finely ground coffee presses into the meat and caramelizes; coarser grounds can leave a gritty texture and won't adhere as well.
Don’t over-char the rub
Because the rub contains sugar and coffee, avoid blistering flames—aim for steady medium-high heat and flip as needed to prevent bitter burning.
Rest before slicing
Let the steak rest 8–10 minutes tented so juices redistribute; slicing too soon squeezes flavor out and yields a drier result.
Slice against grain
Cutting thinly across the grain is essential for flank steak — it shortens muscle fibers and makes each bite more tender.
Adjust chimichurri balance
Taste for acidity and oiliness — if the sauce feels too sharp add a teaspoon of sugar or more oil, and if too oily add a splash more vinegar.
Coffee-Rubbed Grilled Flank Steak with Chimichurri Variations and Substitutions
Espresso-forward rub
Swap finely ground espresso for the coffee for a darker, more concentrated roast note; reduce the amount to 1 tablespoon if using very strong espresso grind to avoid bitterness.
Lime chimichurri twist
Replace red wine vinegar with the juice of one lime and add 1 teaspoon of finely chopped oregano for a brighter, citrusy South American spin that pairs especially well with grilled corn.
Use skirt or hanger steak
Substitute skirt or hanger steak if you prefer an even beefier texture; cook a little less time per side and be extra diligent about slicing thinly against the grain.
Smoky-sweet vegan option
Omit the steak and rub sliced, firm tofu or portobello caps with the coffee-sugar rub before grilling; serve with the same chimichurri for a smoky, plant-based main.
How to Store and Make Coffee-Rubbed Grilled Flank Steak with Chimichurri Ahead
Store leftover sliced steak in an airtight container in the refrigerator for up to 3 days; keep the chimichurri separate in its own jar for up to 5 days to preserve brightness. Reheat the steak gently in a skillet with a splash of broth or a low oven (275°F) wrapped in foil to avoid overcooking — bring back to warm, not piping hot. You can freeze cooked steak for up to 3 months, but texture is best when eaten within a week if refrigerated.
What to Serve With Coffee-Rubbed Grilled Flank Steak with Chimichurri
Serve with charred corn, grilled broccolini, or roasted fingerling potatoes and a wedge of lemon or lime to brighten further. A chunk of crusty bread or warm tortillas is great for mopping up chimichurri, and a glass of medium-bodied Malbec or an easy-drinking amber lager pairs nicely with the coffee-smoky notes.
Coffee-Rubbed Grilled Flank Steak with Chimichurri FAQs
Can I use regular brewed coffee instead of grounds for the rub?
No — brewed coffee won’t provide the texture or concentrated flavor the grounds do. If you don’t have finely ground coffee, pulse whole beans briefly or use finely ground instant espresso as a substitute.
How long can I let the rub sit on the steak?
You can let the rub sit at room temperature for 20–30 minutes as written, or refrigerate covered up to overnight for deeper flavor; keep in mind the brown sugar can increase surface caramelization and char if left too long before grilling.
What internal temperature should I target?
Aim for 125–130°F (52–54°C) for medium-rare, about 135°F for medium; remember the steak will rise a few degrees while resting, so pull it off the grill slightly early.
My chimichurri tastes bitter — what went wrong?
Over-chopping parsley or using too much raw garlic can create a bitter or harsh edge; balance with a little extra vinegar or a touch of sugar and a longer rest so flavors meld before serving.
Can this rub be used on other proteins?
Yes — it works well on pork chops, lamb steaks, or sturdy fish like tuna, though cooking times and temperatures will vary; reduce the amount of coffee for delicate proteins to avoid overpowering them.
