Steak Frites for a Busy Tuesday

To get bistro-style steak frites at home, prioritize the pan temperature and the rest time. Use a heavy cast iron skillet to sear a strip steak, then pull it off the heat when the center is firm to the touch but still gives slightly. Serve it alongside twice-fried potato batons, seasoned aggressively with sea salt the moment they leave the oil.

Ingredients
- 2 8oz strip steaks, room temperature
- 3 russet potatoes, peeled and cut into 1/2-inch batons
- 2 cups neutral oil for frying
- 2 tbsp unsalted butter
- 2 sprigs of fresh thyme
- to taste flaky sea salt and cracked black pepper
Step by step
Fry the potatoes
Heat oil to 325°F. Fry potatoes for 5 minutes until soft but pale. Remove and drain on a rack.
Prepare the steak
Rub steaks with oil and a heavy coating of salt. Heat the cast iron skillet until a drop of water dances and evaporates instantly.
The hard sear
Lay steaks in the skillet. Do not move them for 3 minutes until a dark, mahogany crust forms. Flip and cook for 2 minutes on the other side.
Butter baste
Add butter and thyme. Tilt the pan. Spoon the fat over the steaks for 1 minute. Remove and rest on a board for 8 minutes.
Finish the frites
Increase oil heat to 375°F. Drop the par-fried potatoes back in for 3 minutes until they turn a deep golden brown. Drain, salt immediately, and serve with the sliced steak.
Questions people ask
How do I know the steak is done without a thermometer?
Press the center of the steak. If it feels like the fleshy part of your palm below your thumb, it is medium-rare.
Tips
- Keep the potato batons in a bowl of cold water until you are ready to fry; drain and dry thoroughly before the first fry.
- Use a neutral oil with a high smoke point like grapeseed or refined canola.
- Do not crowd the skillet; if the steaks touch, they will steam rather than sear.
Variations
- Compound butter: Mash soft butter with minced shallot and parsley before spooning over the resting meat.
- Peppercorn finish: Deglaze the steak pan with a splash of cognac and a spoonful of heavy cream to create a quick pan sauce.
