Prepare the Compound Butter
In a small bowl, mash the softened butter with minced tarragon, lemon zest, and Dijon mustard until well combined. Roll into a log using parchment paper and refrigerate until firm, at least 30 minutes.

First Fry for the Potatoes
Soak potato sticks in cold water for 20 minutes to remove starch, then pat completely dry. Heat oil to 160°C (325°F) and fry the potatoes in batches for 5 minutes until pale and soft. Drain on paper towels.

Sear the Steaks
Season steaks heavily with salt and pepper. Heat oil in a heavy cast-iron skillet over high heat until smoking. Sear steaks for 3-4 minutes per side. In the last 2 minutes, add the butter, garlic, and thyme, basting the steaks continuously with the foaming butter. Remove and rest for 10 minutes.

Double Fry and Serve
Increase the oil temperature to 190°C (375°F). Fry the pre-cooked potatoes for 2-3 minutes until deep golden brown and crispy. Drain, season immediately with salt, and serve alongside the rested steak topped with a thick slice of tarragon butter.
Chef's Tips
- Always pat your potatoes completely dry before frying to prevent oil splatter and ensure crispiness.
- Let the steaks sit at room temperature for 45 minutes before cooking for an even internal temperature.
- Use a cast-iron skillet for the best possible crust (Maillard reaction) on your beef.
What to Serve with Classic Bistro Steak Frites with Tarragon Butter
The garlic butter sauce is the star — pick sides that soak it up or balance the richness.
- Serve with a simple green salad dressed in a sharp vinaigrette.
- Pair with a glass of Bordeaux or a peppery Syrah.
- Add a side of Dijon mustard for dipping the steak.
Frequently asked questions
Can I use a different cut of beef?
Yes, Flank steak or Hanger steak (Onglet) are traditional alternatives, though they should be served medium-rare to avoid toughness.
Why double-fry the potatoes?
The first fry cooks the interior, and the second fry creates the crunchy, golden exterior.
