1/2 small bunch ,flat-leaf parsley, finely chopped (optional)
Instructions
In a small bowl, crush capers with the back of a spoon.
In a small pan over medium heat, melt 1/2 tbsp butter until just gold. Add capers and saute until fragrant. Add lemon juice and zest, bringing to a simmer and continuing to cook until liquid is reduced by 1/3. Season to taste with salt and pepper, remove from heat.
Add cold butter into lemon mixture, stirring constantly until butter is completely melted, about 1 minute. Set aside.
Heat a 12-inch skillet over medium-high heat. Lightly season steaks with salt and pepper, then place in pan and cook on one side 2-3 minutes. Flip steaks and add the sauce, cooking another 3 minutes on the other side.
Plate steaks, drizzling remaining sauce over each. If desired, sprinkle parsley over steaks.
