This smoked bone marrow compound butter makes the perfect topping to add that umami punch to your steak or other grilled meats. It is super easy to make and can be portioned and saved for use throughout the year.
Allow the butter to soften and finely chop the parsley.
Heat your grill or smoker to 375-400 degrees and set up for indirect heat. Place the marrow bones in or above a pan and cook until they reach an internal temperature of145-150 degrees and the marrow is starting to pull away from the bone. This typically takes about 25-30 minutes.
Scoop the roasted bone marrow out of the bone and into a bowl. Add in all of the pan drippings, butter, pepper, and parsley and mix to combine.
Roll into a log shape or place into an ice cube tray to make individual portions. Unused potions can be frozen for future use.
