Description

Steak Frites with Herb Mustard is a French bistro classic featuring juicy seared steak served with crispy golden fries and a zesty herb mustard sauce for dipping or drizzling.


Ingredients

Units Scale
  • 2 ribeye or sirloin steaks (about 8 oz each)
  • Salt and freshly ground black pepper, to taste
  • 1 tablespoon olive oil
  • 2 tablespoons butter
  • 2 cloves garlic, crushed
  • 1 sprig rosemary or thyme
  • 1 lb russet potatoes, cut into fries
  • Vegetable oil, for frying
  • 1/4 cup Dijon mustard
  • 1 tablespoon whole grain mustard
  • 2 tablespoons mayonnaise
  • 1 tablespoon chopped fresh parsley
  • 1 teaspoon chopped tarragon (optional)
  • 1 teaspoon lemon juice

Instructions

  1. Preheat oven to 425°F (220°C) for the fries or prepare a fryer to 350°F (175°C) if deep-frying.
  2. Toss potato fries with a bit of oil and bake for 25–30 minutes, turning halfway, until golden and crisp. Alternatively, deep-fry until golden and drain on paper towels.
  3. Season steaks generously with salt and pepper.
  4. Heat olive oil in a cast iron skillet over medium-high heat. Add steaks and sear 3–4 minutes per side for medium-rare, or to desired doneness.
  5. During the last minute of cooking, add butter, garlic, and rosemary/thyme, basting the steak with the melted butter.
  6. Remove steaks and rest for 5 minutes.
  7. In a small bowl, mix Dijon mustard, whole grain mustard, mayonnaise, parsley, tarragon (if using), and lemon juice to make the herb mustard sauce.
  8. Serve the steak sliced with hot fries and a side of herb mustard sauce.

Notes

  • Let steaks come to room temperature before cooking for even searing.
  • Use an air fryer for a crispier and lower-fat fry option.
  • Herb mustard also works well as a sandwich spread or salad dressing base.
