If your idea of barbecue heaven is smoke, spice, and a whisper of whiskey, you’re in for a treat.
This smoked flank steak recipe is all about balance – bold but not harsh, smoky but not bitter, and just fiery enough to make your taste buds wake up.
Flank steak is one of those cuts that doesn’t get enough love. It’s lean, affordable, and quick to cook, but give it a little low-and-slow smoke magic and it turns into something you’d swear came out of a high-end steakhouse.
Add a chili rub and a splash of whiskey? Now you’ve got yourself a new BBQ classic.
Choosing the Right Flank Steak
A great smoked steak starts long before the smoke – it starts at the butcher counter. Flank steak is a thin, lean cut that comes from the cow’s abdominal muscles, known for its rich beefy flavor and visible grain.
Look for a deep red color, light marbling, and an even thickness from end to end so it cooks evenly.
Avoid steaks with too much silver skin – it won’t break down in the smoker and can make slices chewy. And here’s the beauty of it: flank steak is affordable. You don’t need to drop steakhouse money to make something that tastes luxurious.
It’s the blue-collar hero of the beef world – humble, hardworking, and when smoked right, ridiculously tender.
Why You’ll Love This Recipe
There’s a reason this one keeps showing up at my weekend cookouts:
- The chili rub adds a smoky kick without overwhelming the beef.
- Whiskey marinade tenderizes and adds depth, not just flavor.
- It’s fast by BBQ standards – about two hours total.
- The result? Juicy, smoky, flavorful steak that’s just as good on its own as it is in tacos or sandwiches.
It’s also a great “gateway” recipe for anyone just starting with smoking. You don’t need a fancy setup – just patience, good wood, and a drink in hand.
Tips for the Perfect Smoked Flank Steak
- Start at room temperature. Don’t throw cold meat on the smoker.
- Don’t over-smoke. Lean cuts like flank pick up flavor fast – too much and it’ll taste bitter.
- Rest it. Those juices need time to redistribute.
- Experiment with whiskey. Bourbon gives sweetness; rye adds spice.
- For a pro touch, brush the steak with melted butter or beef tallow before the sear. It deepens the crust and adds richness.
The Science Behind the Smoke
Good BBQ is flavor meeting physics. When you smoke meat, compounds like phenols and carbonyls from the burning wood cling to the steak’s surface, creating that deep smoky aroma and signature mahogany color.
Thin blue smoke – not thick white clouds – is your friend here.
Too much smoke, and your steak tastes like an ashtray. The goal is clean combustion, steady airflow, and consistent heat around 225°F. The chili rub acts like armor, holding moisture while letting the smoke kiss the surface.
The result: that perfect balance of whiskey warmth, spice, and savory smoke. Think of it as chemistry that tastes like summer weekends.
Serving Suggestions
This steak doesn’t need much – it’s already showing off. But if you want to round out the meal:
- Serve with roasted potatoes, grilled corn, or smoky beans.
- Slice it thin for BBQ tacos or steak sandwiches.
- Or go fancy: top with chimichurri for a punchy, herbal contrast.
Pair it with a glass of the same whiskey you cooked with. (Chef’s rights.)
Whiskey Choices and Flavor Profiles
The whiskey you choose changes the steak’s entire personality. Bourbon brings sweetness – caramel, vanilla, and warmth – perfect if you like smooth balance. Rye whiskey adds a sharper, spicier edge that plays beautifully with the chili rub.
If you’re bold, experiment with smoky Scotch for a campfire note that pairs well with oak wood. Just don’t use your most expensive bottle; the goal is depth, not decadence.
For a non-alcohol version, swap whiskey for a mix of apple cider and a touch of liquid smoke – you’ll still get that tangy-sweet profile.
Think of whiskey as your secret marinade weapon – it carries flavor deep into the steak fibers while whispering, not shouting, its presence.
Wood Pairings for Smoked Flank Steak
Choosing the right wood for smoking is as important as picking the right whiskey. For bold BBQ flavor, go with hickory – the classic, smoky foundation of Southern barbecue.
Want something milder? Oak delivers balanced smoke that complements the whiskey without dominating it.
For a touch of sweetness, applewood or cherry wood work beautifully, giving your smoked flank steak a hint of fruitiness and a rosy color. Mixing woods is fair game, too – try a half hickory, half apple blend for layered complexity.
It’s like blending whiskey, but with fire and patience. The key is moderation; flank steak doesn’t need to bathe in smoke all day. Give it just enough time to soak up character, not bitterness.
Tips for the Perfect Smoked Flank Steak
- Start at room temperature. Don’t throw cold meat on the smoker.
- Don’t over-smoke. Lean cuts like flank pick up flavor fast – too much and it’ll taste bitter.
- Rest it. Those juices need time to redistribute.
- Experiment with whiskey. Bourbon gives sweetness; rye adds spice.
- Brush with butter or tallow. It deepens the crust and adds richness.
A good smoked steak isn’t about constant fiddling – it’s about control. Keep your fire steady, your patience long, and your tongs light.
Leftovers and Next-Day Magic
If you somehow have leftovers (unlikely, but possible), don’t waste them.
Smoked flank steak is one of the best next-day proteins around. Slice it thin and toss into breakfast hash with eggs and potatoes, or layer it into smoked steak tacos with lime crema and slaw.
Reheat gently in a skillet with a splash of broth or butter to keep it tender. Avoid the microwave – it’ll punish your good work.
You can also turn leftovers into a smoked steak salad with arugula, corn, and a whiskey vinaigrette. If you’re lucky enough to have some left, congratulations – breakfast, lunch, and dinner just upgraded themselves.
Why This Recipe Works
What makes this smoked flank steak shine is the balance of chemistry and control. The whiskey’s alcohol carries flavor deep into the beef, while the chili rub creates a crisp, flavorful crust that seals in moisture. Slow smoking does the rest, gently tenderizing the meat without drying it out. The result is a steak that’s smoky, juicy, and full of layered flavor – not just meat hiding under sauce. This is barbecue done with purpose and patience, where every element works together to elevate a humble flank cut into something worthy of a pitmaster’s pride.
Final Thoughts
Every pitmaster has their “signature move.” This one’s mine. It’s simple, bold, and it makes people stop talking mid-bite.
If you’re tired of brisket marathons and ribs that take all day, give this whiskey-smoked flank steak a shot. It’s a recipe that proves you don’t need 12 hours of smoke to get flavor that feels legendary.
Now grab your smoker, your favorite bourbon, and get cooking – because once that chili-rubbed whiskey aroma hits the air, your neighbors will find excuses to visit.

Ingredients
For the Chili Rub
- 2 tbsp chili powder
- 1 tbsp smoked paprika
- 1 tbsp brown sugar
- 1 tsp garlic powder
- 1 tsp onion powder
- ½ tsp cayenne (optional, if you like it hot)
- 1 tbsp kosher salt
- 1 tsp black pepper
For the Whiskey Marinade
- ¼ cup whiskey (bourbon works best)
- 2 tbsp soy sauce
- 1 tbsp Worcestershire sauce
- 2 tbsp olive oil
- 1 tbsp honey
Main Star
- 1½–2 lbs flank steak, trimmed and ready for glory
Instructions
- Trim and Pat Dry. Start with a clean, dry flank steak. Trim off any silver skin – that thin, shiny layer that refuses to tenderize. If you skip this, you’ll end up chewing like a goat. Don’t be that guy.
- Mix the Marinade. In a small bowl, whisk together whiskey, soy sauce, Worcestershire, olive oil, and honey. Pour it over the steak in a shallow dish or zip bag. Massage it in like you mean it. Then cover and refrigerate for 2–4 hours (overnight if you’ve got time).
- Make the Chili Rub. Combine all the dry ingredients in a small bowl. You’re creating that spicy, smoky armor that’ll protect and flavor the meat during its time in the smoke. Smell that? That’s victory.
- Preheat the Smoker. Bring your smoker to 225°F (107°C). Aim for a clean, thin blue smoke – that’s where the flavor lives. Use hickory or oak wood if you like bold smoke, or applewood if you want something softer and a little sweet.
- Rub It Down. Take the steak out of the marinade, pat it dry, and coat it generously with the chili rub. Every inch matters. Too much rub? No such thing.
- Smoke It. Place the steak directly on the smoker grates. Let it roll for about 1.5–2 hours, or until internal temperature hits 130°F (medium rare). Don’t crank the heat or peek too much. Smoking is a trust exercise.
- Optional: Quick Sear. If you want a crust, sear the steak on a hot grill or cast iron pan for 30–60 seconds per side. This step adds char and locks in that final layer of flavor.
