Ingredients You’ll Need

Every component in this Deliciously Good Flank Steak with Cocoa-Coffee Rub plays a starring role. The ingredients are wonderfully straightforward—but trust me, together they create magic: each brings out the best color, aroma, and, most importantly, unforgettable taste in every bite.

• Flank steak (2 pounds): This lean, flavorful cut takes perfectly to a robust rub and quick grilling. Look for a steak with even thickness for more consistent cooking.
• Ground dark roast coffee (1/2 cup): The backbone of the rub! It adds deep, rich bitterness and a beautiful crust. Use freshly ground for max aroma.
• 100% dark cocoa (1 tablespoon, preferably Valrhona): Cocoa brings subtle earthy bitterness and rounds out the meaty flavors with a savory-sweet edge.
• Brown sugar (1 teaspoon): Just a bit for balance, helping the crust caramelize gorgeously on the grill.
• Chili powder (1/4 heaping teaspoon): For a smoky, gentle heat that complements the cocoa and coffee.
• Cayenne pepper (1 heaping teaspoon): This is where the fun kicks in—heat that wakes up your taste buds without overpowering the steak.
• Paprika (1/4 heaping teaspoon): Use smoked for even more depth, or sweet paprika for a milder approach.
• Olive oil: Adds a bit of richness and helps the rub stick for that signature, flavor-packed crust.
• Salt, to rub on steak: Always season flank steak generously! It draws out moisture and enhances tenderness.

Variations

This recipe is endlessly adaptable—make it your own based on what you have, dietary needs, or how much heat you crave. The cocoa-coffee rub welcomes all sorts of personal twists!

• Go smokier: Swap sweet paprika for smoked paprika, or add a pinch of chipotle powder for an even smokier kick.
• Milder version: Tone down the cayenne if you’re after a gentler heat—try only half the amount, or omit entirely for kids.
• Different cuts: Can’t find flank steak? This rub is equally delicious on skirt steak, flat iron, or even boneless chicken thighs.
• Sweet twist: Love a bit more caramelization? Double the brown sugar for sweeter, stickier results.

How to Make Deliciously Good Flank Steak with Cocoa-Coffee Rub

Step 1: Mix the Cocoa-Coffee Rub

In a bowl, stir together the ground coffee, cocoa, brown sugar, chili powder, cayenne, and paprika until thoroughly mixed. Take in the smell—it’s amazing already! Set aside so it’s ready when your steak is prepped.

Step 2: Salt and Prep the Flank Steak

If you have the time, generously rub salt all over the steak and refrigerate it uncovered overnight or at least two hours before cooking. This dry brining step helps tenderize and season the steak deeply. In a hurry? Just salt right before grilling—it’ll still be fabulous!

Step 3: Fire Up the Grill

Preheat your grill (or grill pan) to high heat. You want it really hot to get that signature seared crust from the cocoa-coffee rub and to lock in all those delicious juices.

Step 4: Oil and Rub the Steak

Drizzle a little olive oil over the steak and massage it in, then press the cocoa-coffee rub onto both sides. Be generous: you want every inch covered so there’s no red showing—this is where those flavors shine!

Step 5: Grill to Perfection

Place the steak directly on the grill grates and cook for about 6–8 minutes per side, depending on thickness and desired doneness. The outside should develop a gorgeous, aromatic crust while the inside stays juicy and pink.

Step 6: Rest, Slice, and Serve

Transfer the steak to a board, tent loosely with foil, and let it rest for 10 minutes. This helps the juices settle back into the meat. Slice thinly against the grain and get ready for the oohs and ahhs. Deliciously Good Flank Steak with Cocoa-Coffee Rub is best served fresh, but extra rub can be stored for your next batch!

How to Serve Deliciously Good Flank Steak with Cocoa-Coffee Rub

Garnishes

This steak already packs big flavor, so a little sprinkle of flaky sea salt or a shower of fresh chopped parsley is all you need to highlight its juicy beauty. If you’re feeling fancy, a quick drizzle of good olive oil or a dollop of horseradish sauce will make each bite extra special.

Side Dishes

I love serving Deliciously Good Flank Steak with Cocoa-Coffee Rub alongside bright, fresh salads; think arugula with lemon or a juicy tomato salad. It’s also amazing with grilled corn, crispy roasted potatoes, or garlic butter green beans—anything sturdy enough to mingle with that smoky, chocolatey rub.

Creative Ways to Present

Sliced steak looks gorgeous fanned out on a rustic wooden board, especially with a few fresh herbs tossed over for color. For a fun twist, serve the steak in tacos with pickled onions and lime, or pile slices over toasted sourdough with a little chimichurri for a steakhouse-style open sandwich.

Make Ahead and Storage

Storing Leftovers

Wrap any leftovers tightly in foil or place in an airtight container. They’ll keep in the fridge for up to 3 days, ready to be enjoyed cold in salads, wraps, or steak sandwiches.

Freezing

Yes, you can freeze Deliciously Good Flank Steak with Cocoa-Coffee Rub! Let slices cool completely, then layer between parchment in a freezer bag. They’ll keep beautifully up to 2 months—just thaw overnight in the fridge before using.

Reheating

For best flavor and moisture, reheat slices very gently in a covered skillet over low heat or wrapped in foil in a 300°F oven. Avoid microwaving if possible, as it can make the steak tough. Serve with a splash of olive oil or horseradish sauce to freshen it back up!
