Classic Steak Frites
Ribeye Steak Frites — Twice-Fried Potatoes with Perfect Seared Beef
There's a reason this combination rules French bistros — the contrast between a crusty-edged, pink-centered steak and golden, twice-cooked frites is pure magic. The technique matters here: proper double-frying creates fries with crisp shells and fluffy centers, while the cast iron gives you that restaurant-quality crust.
The marriage of steak and frites didn't happen by accident — it's the result of French cooks understanding that contrasting textures make each other shine brighter. When you bite through the crispy shell of a properly twice-fried potato and hit that fluffy interior, then follow it with a piece of perfectly seared ribeye, the interplay is what elevates a simple meal into something memorable.
The double-fry method is where most home cooks stumble, but it's actually straightforward once you understand the logic. That first low-temperature fry cooks the potato through without browning — think of it as par-cooking. The second high-heat fry creates the golden crust while the interior stays light and airy. Meanwhile, your cast iron is doing its own magic on the ribeye, building that restaurant-quality crust that seals in the juices.
This isn't about showing off with expensive ingredients or complicated techniques. It's about executing two simple processes — double-frying potatoes and properly searing meat — with the kind of attention that transforms everyday cooking into something special. The timing works out perfectly: while your steaks rest, the frites get their final crispy treatment, so everything hits the plate hot and at its peak.

Ingredients
Steak
- 4 ribeye steaks, 1-inch thick (room temperature works best)
- 2 tbspvegetable oil with high smoke point
- 2 tbspunsalted butter
- 2 clovegarlic cloves, lightly crushed with flat knife
- 2 sprigfresh thyme sprigs
- kosher salt and freshly cracked black pepper
Frites
- 2 lbrusset potatoes, peeled and cut into 1/2-inch strips
- neutral oil for deep frying (enough for 3-4 inches depth)
- fine sea salt for finishing
Instructions
- Fill a heavy pot or deep fryer with oil to 3-4 inch depth and heat to exactly 325°F. Use a reliable thermometer — the temperature precision makes the difference between soggy and crispy fries.
- Drop potato strips into the oil in small batches, avoiding overcrowding. Fry for 3-4 minutes until they're cooked through but still pale — this first fry cooks the interior. Transfer to paper towels.⏱ 4 min
- Season both sides of the steaks heavily with salt and pepper, then let them sit on the counter. This brings them to room temperature for even cooking and starts the seasoning process.⏱ 10 min
- Place your cast iron skillet over high heat and add the vegetable oil. When the oil starts smoking lightly, it's ready — this high heat creates the crust you're after.
- Lay the steaks in the pan without moving them. Sear for 3-4 minutes until a deep brown crust forms, then flip once. The crust should release easily when it's ready.⏱ 4 min
- Drop the butter, crushed garlic, and thyme into the pan. Tilt the skillet and baste the steaks with the foaming butter mixture, spooning it over continuously for rich flavor.⏱ 1 min
- Transfer steaks to a cutting board and tent loosely with foil. This resting period lets the juices redistribute — skip it and they'll run all over your plate when you cut.⏱ 5 min
- Crank the oil temperature up to 375°F for the second fry. Drop the pre-cooked potatoes back in and fry until deep golden brown and crispy, about 2-3 minutes.⏱ 3 min
- Lift the fries from the oil and immediately hit them with salt while they're still glistening. The residual oil helps the salt stick and creates the perfect seasoned exterior.
- Plate the rested steaks alongside the hot frites and serve immediately. The contrast between the warm, juicy steak and crackling-crisp potatoes is what makes this combination legendary.
Tips & Tricks
- Cut your potato strips as evenly as possible — inconsistent sizes mean some fries will be overcooked while others stay soggy.
- Don't skip the resting step for the steaks; those juices need 5-10 minutes to redistribute or you'll lose them on the cutting board.
- Keep the oil temperature steady with a good thermometer — even 25-degree swings will affect your fry texture.
- Pat the steaks completely dry before seasoning, then let them sit 15-20 minutes to come to room temperature for even cooking.
- Save the garlic-thyme butter from the pan — it makes an excellent finishing sauce drizzled over the sliced steak.
Frequently Asked Questions
Can I use a different cut of steak for this recipe?
Strip steak or sirloin work well, but ribeye's marbling makes it particularly suited to high-heat searing. If using leaner cuts, watch the internal temperature carefully to avoid overcooking.
What if I don't have a deep fryer or thermometer?
Use a heavy pot with at least 3 inches of oil and test temperature by dropping in a small piece of potato — it should bubble steadily at 325°F, vigorously at 375°F. A candy thermometer works if you don't have a deep-fry thermometer.
Can I prep the frites ahead of time?
After the first fry, you can store the par-cooked potatoes in the refrigerator for up to 24 hours. Let them come to room temperature before the second fry, or add an extra 30 seconds to the cooking time.
How do I know when my steak is done without cutting into it?
Use a meat thermometer: 120-125°F for rare, 130-135°F for medium-rare. The steaks will continue cooking slightly while they rest, so pull them 5 degrees before your target temperature.
