Combine marinade ingredients and shake or stir well to combine. Place trimmed (if necessary remove excess fat/silver) in a shallow dish and pour marinade over.
Cover and place in fridge. Turn meat every so often. Marinate for 90 minutes up to overnight.
If garlic paste clumps up, smooth it over the meat with your clean hands.
When ready to cook, pull steak from fridge 30 minutes or so before cooking. Pat dry, and allow to sit at room temp.
Fire up your cleaned and oiled grill or heat a cast iron pan, your Blackstone Griddle or heavy bottomed pan over high heat.
Season your meat with S&P
Add avocado oil to pan (you could even use some of the leftover marinade as well). Place steaks in hot pan/grill and sear on all sides.
Add butter to skillet as well as any aromatics you like (and red pepper flakes if using). Keep turning meat until the sear is to your liking and the temp is to your liking. Should take 10-14 minutes to cook depending on size and your preference for doneness.
For rare, pull at 120-125 degrees internal, for medium-rare pull at 130, for medium pull at . Remember the meat will continue to cook for minutes after pulled. 135-145 (145 is too high for me I err on 5 degrees lower).
Always let the steaks rest for at least 5-8 minutes to allow the cook to continue and the juices to stay inside the meat and redistribute vs flowing out onto the plate.
