Pin it
This is the dinner I make when I want a restaurant feeling without the reservation. A hot pan, a good strip steak, and a pile of crispy frites. The herb-lemon butter is the only flourish you need. Most of the time is hands-off while the potatoes soak and the butter softens. From start to finish you are looking at just under an hour.
The trick is timing. You par-cook the frites first, then sear the steak while the potatoes rest. Once the steak is resting, you give the frites their final fry. Everything lands on the plate hot at the same time.
What goes on the plate
Quality matters here because the ingredient list is short. Buy the best steak you can afford and use real unsalted butter so you control the salt yourself. Russet potatoes are non-negotiable for that fluffy interior.
- New York strip steaks. Well-marbled and at least one inch thick so they can take a hard sear without overcooking.
- Russet potatoes. High starch means a crisp shell and a soft center after the double-fry.
- Unsalted butter. The base of the compound butter and the basting fat. Salted butter would push the seasoning too far.
- Fresh thyme, rosemary, and parsley. Woody herbs for the basting butter, soft parsley for the compound butter.
- Garlic. Smashed cloves perfume the pan during the sear. Minced garlic goes into the compound butter.
- Lemon. Both zest and juice wake up the rich butter and cut through the fat of the steak.
- High-heat oil. Avocado or grapeseed oil handles the screaming hot pan without burning.
How it all comes together
- Make the compound butter. Soften the butter for thirty minutes, then beat it until creamy. Fold in minced parsley, thyme, rosemary, garlic, lemon zest, juice, salt, and pepper. Spoon onto parchment, roll into a log, and chill.
- Par-cook the frites. Cut the potatoes into quarter-inch batons and soak in cold water for thirty minutes. Drain and dry thoroughly. Fry at 300°F for three minutes until tender but pale. Drain on a rack.
- Sear the steaks. Pat the steaks completely dry and season hard with salt and pepper. Heat oil in a heavy skillet until smoking. Lay the steaks in and press gently for ten seconds so they make full contact. Sear undisturbed for three minutes. Flip, add butter, smashed garlic, and thyme sprigs, then baste for two to three minutes. Transfer to a warm plate to rest.
- Crisp the frites. While the steak rests, raise the oil to 350°F. Fry the potatoes again for three to four minutes until deeply golden and crisp. Drain, toss with coarse salt, and keep warm.
- Slice and serve. Cut the chilled compound butter into coins. Slice the steak against the grain and fan over the plate. Pile the hot frites alongside and top the steak with the butter so it melts over the slices.
The double-fry that changes everything
One fry is not enough. The first pass at a lower temperature gently cooks the potato through without color. The second pass at a higher temperature blasts away the surface moisture and creates the shatteringly crisp shell. If you skip the soak or the first fry, you end up with either raw centers or limp fries. Dry the batons completely after soaking. Water and hot oil do not mix. A wire rack after the first fry helps steam escape so the crust can set up properly. This same technique works for other fried potato recipes, but here it is essential because the frites need to stand up to the juices from the steak.
Sear and baste like a pro
A cast iron skillet is your best friend for this step. It holds heat evenly and builds the dark crust that makes steak taste like steak. The key is leaving the meat alone once it hits the pan. If you poke and scoot it around, you break the crust before it forms. After the flip, tilt the pan slightly and spoon the foaming butter, garlic, and thyme over the top. This is called basting, and it seasons the surface while it finishes cooking. The smell at this stage is incredible. Pull the steaks when they are five degrees below your target temperature because carryover heat will push them the rest of the way while they rest. If you want another steak dinner with a different presentation, lemon herb butter steak with mashed potatoes uses the same butter idea on a different plate.
Swaps when you need them
Ribeye works beautifully here if you prefer more marbling. Filet mignon is leaner and faster cooking, so pull it a minute earlier. For the frites, Yukon Golds will work but they will be slightly denser and less fluffy inside. If deep frying is not an option, you can oven-roast thick-cut potato wedges at 425°F with plenty of oil and still get good results, though they will not be identical to true frites. For a quicker weeknight version, try the air fryer garlic butter steak approach. It skips the oil pot entirely.
Resting is not optional
Resting the steak is the easiest step and the one most people rush. When the steak comes off the heat, the juices inside are agitated and near the surface. Slice too soon and they run out onto the board, leaving you with dry meat. Four minutes on a warm plate tented loosely with foil gives the juices time to settle back into the fibers. During those four minutes you finish the frites, so no time is wasted. The same rest rule applies to garlic butter steak bites with parmesan cream sauce. Small pieces still need a minute or two off the heat.
FAQs
- What cut of steak works best for steak frites?
New York strip is the classic choice because it balances tenderness with enough fat for flavor. Ribeye is richer and filet mignon is leaner, but both work well with the same timing adjusted slightly.
- Can I bake the fries instead of frying?
Yes, though they will be roasted potatoes rather than true frites. Toss batons with oil and bake at 425°F for about thirty-five minutes, flipping once, until crisp and golden.
- How do I know when the steak is done?
Use an instant-read thermometer. Pull the steak at 120°F for rare, 130°F for medium-rare, or 140°F for medium. The USDA recommends a minimum internal temperature of 145°F for safety. See the USDA beef cooking guidelines.
- Can I make the herb-lemon butter ahead?
Absolutely. Roll it into a log, wrap it tightly, and refrigerate for up to five days or freeze for three months. Slice coins as needed.
- What oil is best for frying the potatoes?
Use a neutral oil with a high smoke point such as peanut, canola, or avocado oil. Olive oil will smoke too quickly at frying temperatures.
- How do I reheat leftover steak frites?
Reheat the steak gently in a covered skillet with a splash of water over medium-low heat. Crisp leftover frites in a 400°F oven or air fryer for five minutes.
- Why do my fries turn out soggy?
Usually because the potatoes were not dry enough before frying or the oil temperature was too low. Use a thermometer and dry the cut potatoes thoroughly with a clean towel.
