Ingredients
Units
Scale
- 2 ribeye or sirloin steaks (about 1 inch thick)
- Salt and black pepper to taste
- 2 tablespoons olive oil
- 2 tablespoons unsalted butter
- 2 cloves garlic, smashed
- 2 sprigs fresh thyme
- 1 lb (450g) russet potatoes, cut into fries
- Vegetable oil for frying
- Fresh parsley, chopped (for garnish)
- For the Herb Mustard Sauce:
- 2 tablespoons Dijon mustard
- 1 tablespoon whole grain mustard
- 1 tablespoon chopped fresh parsley
- 1 teaspoon chopped fresh tarragon (optional)
- 2 tablespoons olive oil
- 1 teaspoon lemon juice
Instructions
- Start by soaking the cut potatoes in cold water for 30 minutes to remove excess starch. Drain and pat dry.
- Heat vegetable oil in a deep pot or fryer to 350°F (175°C). Fry the potatoes in batches until golden and crispy, about 3-4 minutes per batch. Drain on paper towels and season with salt.
- Season the steaks generously with salt and black pepper.
- Heat olive oil in a skillet over medium-high heat. Add the steaks and sear for 3-4 minutes per side for medium-rare, adding butter, garlic, and thyme in the last 2 minutes. Baste the steaks with the melted butter.
- Remove steaks and let them rest for 5 minutes before slicing.
- To make the herb mustard, whisk together Dijon, whole grain mustard, parsley, tarragon (if using), olive oil, and lemon juice in a bowl.
- Serve the sliced steak with crispy fries and a spoonful of herb mustard on the side. Garnish with chopped parsley.
Notes
- For extra crispy fries, double-fry: first at a lower temp (300°F), then again at 375°F for color and crunch.
- Let steaks rest after cooking to keep them juicy.
- The herb mustard can be made ahead and stored in the fridge for up to 3 days.
