I have to give credit for this recipe where it’s due. A couple of years ago, we traveled to Washington, DC, and one of our best dining experiences was at the Blue Duck Tavern, a stunning restaurant matched by its unique and beautifully prepared plates. (Along with Chef Jose Andres’ restaurant Jaleo, it is the restaurant I recommend to any friends in the DC area, and one I would go back to in a heartbeat.)
One of the most memorable appetizers I enjoyed was the roasted beef bone marrow, which had a delicious pretzel crumble on top. The moment I had a taste, I knew that I would have to recreate this for myself at home.

Bone marrow played an important role in the evolution of early man. Perhaps that’s why some of us still have that primitive craving for it.
Early man had small teeth and ate anything he could lay his hands on, especially meat. But he was no hunter. Attracted by circling vultures, he probably scavenged the leftovers from a big kill such as an antelope left in a tree by a leopard, or a large animal such as a wildebeest that had been slaughtered by lions.
Because meat is relatively easy to digest and rich in calories and nutrients, early man lost the need for the big intestines of apes and earlier hominids. This freed up energy for use by other organs. This surplus of energy seems to have been diverted to one organ in particular – the brain. But scavenging meat from under the noses of big cats is a risky business, so good scavengers needed to be smart. At this stage in our evolution, a big brain was associated with greater intellect. Big brains require lots of energy to operate: the human brain uses 20% of the body’s total energy production. The concentrated calories and nutrition found in meat was responsible for an increase in the brain size of early humans.
But around two million years ago, telltale cut marks on the surface of animal bones reveal that early humans were using crude stone tools to smash open the bones and extract the marrow. Stone tools allowed early man to get at a food source that no other creature was able to obtain – bone marrow. Bone marrow contains long chain fatty acids that are vital for brain growth and development. This helped further fuel the increase in brain size, allowing our ancestors to make more complex tools. Many historians believe that the blunt force required to break bones with tools to extract the bone marrow was a crucial ingredient in the development of the human hand, and the unique dexterity it has over that of apes.
Of course, these days, we can simply go to our butcher and ask them to slice some beef bones for us so that we can enjoy the marrow like our ancestors did. It’s much more civilized.
My box o’ frozen bones. I ordered about 25 lbs. of marrow bones from Slanker’s, a grass-fed beef farm in Texas.
They key to roasting marrow bones properly is to keep an eye on them. The bones can go from frozen solid to blazing hot in no time, and that means the marrow can go beyond its rich, gelatinous perfection into a puddle of fat at the bottom of your pan in mere moments.
3 lbs. beef marrow bones (I like them sliced lengthwise)
3/4 cup finely ground salted pretzel sticks
1 teaspoon dried parsley flakes
1 teaspoon granulated onion
1/2 teaspoon granulated garlic
1/4 teaspoon black pepper
olive oil
I keep the beef bones frozen, moving them to the fridge until I’m ready to roast them.
Pre-heat the oven to 450 degrees.
Grind them up!
Place a handful of salted pretzel sticks in a food processor, and pulse them until the pretzels are ground fine. When you’ve got 3/4 cup of ground pretzel powder, move it to a bowl and add the parsley, onion, garlic and black pepper. No salt is needed if the pretzels are salted.
Lay the bones flat on a baking pan. If they wobble, place them on a layer of coarse salt to hold them steady. Sprinkle the pretzel mix on the bones, a little drizzle of olive oil on top, and place them in the oven.
Now you watch…there’s that one point where they go from “not quite yet” to perfection to “Oops! Too much!” …so be careful!
Perfection!
Some toasted bread on the side is all you need!
If you’re cooking gluten-free, try Snyder’s of Hanover GF pretzels. They are awesome…you’ll never know the difference.
