Filet Mignon with Bearnaise Sauce

Ingredients

• 1/2 tsp table salt, or to taste, divided
• 1/2 tsp black pepper, freshly ground, or to taste, divided
• 1 pound(s) uncooked lean and trimmed beef filet mignon, use four 4 oz pieces
• 2 spray(s) cooking spray
• 1 large uncooked egg yolk(s)
• 1 Tbsp water, at room temperature
• 2 1/3 Tbsp unsalted butter, melted
• 1 tsp fresh lemon juice
• 1 1/2 Tbsp chives, and/or parsley, fresh, minced.

Instructions

1. Rub 1/4 teaspoon each salt and pepper all over steak.
2. Coat a grill pan with cooking spray; set over medium-high heat. Heat pan until it?s almost smoking and sizzles when water is dropped onto pan surface.
3. Place steak on pan and cook, without turning, about 5 minutes. Flip steak; cook about 4 to 6 minutes more for medium doneness.
4. Remove steak to a cutting board and loosely cover with aluminum foil; let rest for at least 10 minutes (steak will continue to cook under foil).
5. Meanwhile, to make sauce, bring a small saucepan one-third filled with water to a boil (creating a double boiler). In a metal bowl, beat egg yolk with 1 tablespoon room temperature water until frothy; set bowl over saucepan and cook, stirring constantly, until egg yolk thickens, about 3 to 5 minutes. Remove egg yolk from heat; slowly whisk in melted butter until well-combined. Stir in lemon juice and remaining salt and black pepper; whisk in fresh herbs. Serve steak with sauce.
