Ingredients
Method
Preparation
- Peel and cut the potatoes into thin sticks. Soak the sticks in cold water for 30 minutes to remove excess starch.
- Drain and pat the potatoes dry with a paper towel.
Cooking the Fries
- Heat the oil to 150°C (300°F) in a heavy pot. Fry the potatoes for 5 minutes, allowing them to soften but not brown.
- Cool the fries on a rack to prevent steaming.
Cooking the Steak
- While the fries cool, season the steaks with salt and pepper.
- Preheat a skillet over medium-high heat. Sear the steak for 3–4 minutes on each side until browned. Optionally, baste with butter in the last minute.
- Remove the steak and let it rest for 10 minutes.
Final Cooking of Fries
- Increase the oil temperature to 190°C (375°F) and fry the potatoes until golden and crispy.
- Season the fries with salt immediately after frying.
Making the Sauce
- In a saucepan, combine white wine vinegar, water, shallots, tarragon, and black pepper. Simmer until reduced by half.
- Strain the reduction and keep it warm.
- In a heatproof bowl, whisk the egg yolks with the warm vinegar reduction over simmering water.
- Slowly whisk in the hot melted butter to create a smooth sauce.
- Adjust the seasoning if desired.
Serving
- Slice the rested steak against the grain, spoon warm Béarnaise sauce over the top, and serve with hot fries.
- Optionally, sprinkle fresh herbs over the dish.
Notes
Leftover steak can be stored in the fridge for up to 3 days. Fries are best enjoyed fresh but can last 2 days in storage. Reheat gently. Consider frying the potatoes in advance for convenience.
