These perfectly pan-seared and baked sirloin steaks are juicy and moist, best part is it’s topped with a great herb butter which brings incredible flavor.
Add all ingredients to a medium bowl and mash with a fork until combined. Scoop the herbed butter onto a sheet of parchment or wax paper. Roll and shape it into a thick log. Twist the ends of the paper to seal. Refrigerate until firm, about 30 minutes.
Leave the steak out at room temperature for 30 minutes prior to cooking. Pat the steaks down with a paper towel to dry them completely. Season with salt and pepper.
Preheat oven to 400 degrees F.
In a large, oven-proof skillet (preferably cast iron skillet), heat avocado oil over medium/high heat. Once skillet is hot, add the steaks, make sure they are not being crowded in the pan. Cook steaks 2-3 minutes per side. Place cast iron skillet into preheated oven. Continue to cook for 5-6 minutes for medium/rare. 6-7 minutes for medium. 7-9 minutes medium/well done.
Remove from oven and let steaks rest for at least 5 minutes before serving. Top with herb butter slices and serve.
