You’re sitting at a cramped zinc bar in the 6th Arrondissement. The air smells like rendered beef fat and red wine. A plate slides toward you, piled high with golden, spindly fries and a sliced hanger steak bleeding juice into a puddle of herb butter. It’s perfect. It’s also incredibly hard to replicate at home if you follow the generic recipes floating around the internet. Most people fail because they treat it like a "steak and chips" dinner rather than a technical exercise in temperature management.
Let’s be honest. Making steak frites is a mess. It’s smoky. It’s frantic. If you aren't slightly stressed about the oil temperature while simultaneously basting a piece of beef, you’re probably doing it wrong. But the payoff? Better than anything you’ll pay $50 for at a trendy French spot in Manhattan or London.

The Meat Matters More Than the Price Tag
Don’t buy a filet mignon for this. Just don't. A filet is soft and buttery, but it lacks the iron-rich punch needed to stand up to fried potatoes. Traditionally, French bistros use bavette (flap steak) or onglet (hanger steak). These cuts are fibrous. They have grain. They have soul. If you can't find those, a well-marbled ribeye or a New York strip is fine, but you’re losing that authentic "chew" that defines the dish.
Anthony Bourdain used to swear by the hanger steak for a reason. It’s the "butcher's cut." It hangs from the diaphragm and does a lot of work, which means it’s packed with flavor. However, it has a thick membrane running through the middle that you have to remove, or you'll be chewing on a rubber band all night.
Sourcing the Beef
- Hanger Steak: Intense, mineral flavor. Must be cooked rare or medium-rare. Anything more and it turns into an old boot.
- Ribeye: The fat content is king here. The rendered cap fat mixes with the fry salt in a way that’s almost criminal.
- Flank or Flap: Leaner, but great if you slice it thin against the grain.
The Potato Paradox: Why Your Fries are Soggy
The biggest lie in home cooking is that you can make great frites in an air fryer. You can't. You need oil. Specifically, you need a neutral oil with a high smoke point like peanut or canola. But the real secret used by the legends—think Pierre Koffmann—is the double fry.
If you just drop raw potato sticks into hot oil, the outside burns before the inside softens. You end up with a bitter, crunchy shell and a raw middle. Total disaster. You have to blanch them first at a lower temperature ($325^{\circ}F$ or $160^{\circ}C$). This cooks the starch through. Then, you pull them out, let them rest (this is vital for moisture evaporation), and crank the heat to $375^{\circ}F$ ($190^{\circ}C$) for the final crisp.
How to Make Steak Frites Without Ruining Your Kitchen
Start with the potatoes. Use Russets or Maris Pipers. They have the starch. Peel them, or don't—bistros usually go skinless for a cleaner look. Cut them into "batonnet" shapes, roughly a quarter-inch thick. Soak them in cold water for at least an hour. This leaches out excess surface starch so they don't stick together and turn into a giant potato brick in the fryer.
Dry them. I mean really dry them. Water and hot oil are enemies. Use a kitchen towel and pat them until they feel like paper.
The First Fry (The Blanch)
Heat your oil in a heavy-bottomed pot. Use a thermometer. Don't eyeball it. When it hits $325^{\circ}F$, drop the potatoes in batches. They shouldn't brown. They should just look limp and pale, like they’ve had a long day at the office. This takes about 5 to 6 minutes. Drain them on a wire rack. Avoid paper towels at this stage; they trap steam and make things mushy.
The Steak Execution
While the fries are resting, get your pan screaming hot. Cast iron is the only way to go. If you’re using non-stick, stop. You need the Maillard reaction—that beautiful brown crust that forms when proteins and sugars hit high heat.
Season the steak heavily with Kosher salt. Skip the pepper for now; it burns at high temps and turns bitter. Rub a tiny bit of oil on the steak itself rather than pouring a pool of oil into the pan. This reduces the smoke alarm triggers.
- Sear: Lay the steak away from you so you don't get splashed.
- Wait: Don't touch it for at least 2 minutes. You want a crust.
- Flip: Turn it over. Now comes the magic.
- The Butter Baste: Drop in a massive knob of unsalted butter, three crushed garlic cloves, and a sprig of thyme.
- Spoon: Tilt the pan so the foaming butter pools at the bottom. Spoon that hot, garlic-infused fat over the steak repeatedly. This is how you get that deep mahogany color.
Use an instant-read thermometer. Pull the steak at $125^{\circ}F$ ($52^{\circ}C$) for medium-rare. It will carry over to $130^{\circ}F$ ($54^{\circ}C$) while resting. REST THE STEAK. Give it 10 minutes. If you cut it now, all the juice runs onto the board and your fries get soggy. Nobody wants soggy fries.
The Finishing Move: The Second Fry
While the steak rests, bring that oil up to $375^{\circ}F$. Drop the blanched fries back in. This time, it only takes 2 or 3 minutes. They will puff up and turn GBD—Golden, Brown, and Delicious. Toss them in a metal bowl with fine sea salt while they’re still glistening with oil. The salt needs the oil to stick.
The Sauce Debate: Maître d'Hôtel Butter vs. Béarnaise
A "pure" steak frites usually relies on a compound butter. It’s simpler and, frankly, better for a home cook. Mash softened butter with parsley, lemon juice, salt, and a tiny bit of shallot. Put a disc of that on the hot steak and let it melt into a sauce.
If you’re feeling ambitious, make a Béarnaise. It’s basically Hollandaise’s cooler, more sophisticated cousin. You need an egg yolk emulsion, clarified butter, and a reduction of tarragon and vinegar. It’s finicky. It breaks easily. But when it works, it’s the best sauce on the planet. Honestly, though? Most days, a good Dijon mustard on the side is all you actually need.
Common Mistakes You’re Probably Making
Crowding the pan is the number one killer of steak quality. If you put two big ribeyes in a small skillet, the temperature drops instantly. Instead of searing, the meat steams in its own grey juices. It’s depressing to look at. Cook in batches if you have to.
Another one? Using "new" potatoes. They have too much moisture and not enough starch. They’ll never get crispy. Stick to the old, dusty-looking Russets.
Also, stop using extra virgin olive oil for frying. It has a low smoke point and tastes weird when it’s heated that high. Save the expensive olive oil for your salad. Use peanut oil or beef tallow if you want to go full-throttle traditional.
Why This Dish is the Ultimate Test
Steak frites is about timing. It’s a dance. You want the steak to finish resting exactly when the fries come out of their second bath. It takes practice. The first time you do it, the fries might be cold or the steak might be overcooked. That’s fine. Even the best chefs in Paris have off nights.
The beauty of the dish lies in its simplicity. Salt, fat, potato, protein. When you get the crust on the beef just right—that crunch followed by the tender, red center—and you pair it with a fry that snaps when you bite it, you’ve mastered one of the pillars of Western cooking.
Critical Action Steps for Your Next Attempt
- Dry the Potatoes Twice: Once after cutting, and once after the first fry. Moisture is the enemy of crispiness.
- Check the Grain: Always slice your steak against the grain. If you see long fibers running horizontally, cut vertically across them. This shortens the muscle fibers and makes the meat melt in your mouth.
- Salt Early: Salt your steak at least 45 minutes before cooking, or immediately before hitting the pan. Anything in between causes moisture to sit on the surface, ruining your sear.
- Invest in a Thermometer: Don't use the "finger test" for steak doneness. It’s unreliable. A digital probe is the only way to be 100% sure.
- Warm Your Plates: Professional secret—put your serving plates in a low oven for five minutes. It keeps the fries hot while you’re eating.
Finish the plate with a handful of dressed watercress. The peppery bite cuts through the heavy fat and makes you feel slightly better about the half-pound of butter you just consumed. Drink a young, tannic red wine—a Malbec or a Cabernet Sauvignon works, but a Beaujolais is the classic bistro choice. Eat quickly. Steak frites waits for no one.
