Steak Frites for a Busy Tuesday

This is the lunch that clears your head. It relies on the contrast between a dark, salt-crusted exterior on the meat and the pale, soft interior of a potato fried until the edges shatter.

Before you start

Dry meat is the only non-negotiable.

Pat your steak with paper towels until it is bone-dry before it touches the oil. Moisture is the enemy of a proper crust.

  • heavy-bottomed pot for frying

  • 2 tbspunsalted butter
  • 2sprigs of fresh thyme

The key technique

Control the butter foam

Once the steak has a deep brown sear, drop the heat and add butter and thyme. Tilt the pan and spoon the foaming, herb-infused fat over the steak repeatedly until the meat reaches your desired finish.

Step by step

The method.

  1. Fry the potatoes

    Heat oil to 325°F. Fry potatoes for 5 minutes until soft but pale. Remove and drain on a rack.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

Variations

Other turns to take.

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.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Keep the potato batons in a bowl of cold water until you are ready to fry; drain and dry thoroughly before the first fry.

Tip

Use a neutral oil with a high smoke point like grapeseed or refined canola.

Tip

Do not crowd the skillet; if the steaks touch, they will steam rather than sear.

Questions

The ones that keep coming up.

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.
