  • 4 sirloin steaks about 1 1/4 pounds
  • 1 tablespoon olive oil
  • salt and pepper to taste
  • 2 teaspoons mesquite seasoning see note

garlic herb butter

  • 1/2 cup butter softened
  • 1/2 teaspoon garlic powder
  • 1 teaspoon minced garlic
  • 1 tablespoon finely chopped fresh parsley see note
  • 2 teaspoons fresh thyme see note


  • Stir together butter, garlic powder, garlic, and herbs. Set aside.
  • Pat steaks dry with a paper towel.
  • Rub steaks all over with olive oil.
  • Season steaks with salt and pepper to taste, and mesquite seasoning.
  • Cook steaks 5-8 minutes on each side (or until cooked to desired doneness - I like mine medium-well at about 145 degrees internal temperature) in a skillet over medium heat OR on a grill over medium heat. (See note for oven instructions)
  • Allow steaks to rest at least 5 minutes.
  • Top with garlic herb butter and serve.


For the steaks: I typically look for steaks at least 3/4 inch thick for tenderness and flavor!
Mesquite seasoning: I use McCormick's Grill Mates Mesquite seasoning and I keep a bottle of it in my pantry at all times - it is one of my favorite go-to tricks for livening up a piece of steak, chicken, pork, or even seafood and vegetables. 
Fresh herb substitute: If you don't have fresh herbs, you can use 1 teaspoon Herbs de Provence (my favorite dried herb blend!) or your favorite Italian seasoning blend. 
Oven instructions: Sear steaks in a cast-iron pan over high heat for 1-2  minutes. Flip, then transfer the pan to your oven (preheated to 450 degrees) for 10 minutes (6 minutes for thinner cuts). Allow to rest at least 5 minutes before slicing.
