Ingredients

Cowboy Butter

  • 8 tbsp / 120g Unsalted Butter, softened (see notes)
  • 2 tbsp very finely diced Fresh Parsley
  • 1 tbsp very finely diced Fresh Chives
  • 1/2 tsp (not tbsp!) very finely diced Fresh Thyme Leaves

Instructions

  • Combine all of the cowboy butter ingredients in a small mixing bowl.
  • Pat the steaks dry then generously season both sides with salt and pepper. Add a large cast-iron or heavy-based pan over high heat. Once the pan is very hot, add the oil and leave for 5-10 seconds. For medium-rare, add the steaks and leave undisturbed for 2 minutes. Flip them over and fry for 2 minutes, then remove and rest them to one side for 5 minutes.
  • Serve the steak with your desired amount of butter and enjoy!

Notes

a) Butter - I like the butter to be soft enough to spoon over the steak, but not quite fully melted where the ingredients separate. A little creamy if you will. Just pop the butter in the microwave for 5 second blasts until you reach this consistency (careful - it'll melt quickly!).
b) Storage - The butter will definitely serve more than two steaks, so just tightly cover the rest in the fridge for 4-5 days (can also freeze long-term). Making this ahead of time will give time for the flavours to marry together!
c) Steaks - You can use any steaks you like and cook to your preference, here I've just used what I normally go for. It's really difficult to offer exact timings, but I find an 8oz/220g steak typically takes around 2 minutes on each side in a piping hot pan to offer a medium-rare finish with a nice crust.
d) Serving - Here I've served with oven fries (no shame) and a simple side salad. Check out my Side Dishes for more inspo!
e) Calories - For 1 tbsp of the butter.
