Roasted Bone Marrow and bacon onion jam

Roasted bone marrow

Bone marrow is one of those expensive appetizers or small plate items on the menu. They are delicious on a toasted baguette and some kind of onion jam. However, you can roast bone marrow at home. Not all butchers will cut the bone marrow lengthwise but that’s okay you can still roast them and eat them just as well.

You can find bone marrow in most international market places for relatively cheap, sometimes there is a sale of $1.99 per lb.  I got mine on sale for $1.99 per lb. and decided to roast my own bone marrow.

The first thing you have to do with bone marrow is a blood bath and clean it overnight in the Refrigerator using a saltwater mixture.  Basically,  take the bones out of the original package.  Rinse thoroughly in the sink and cut/scrape off any side flesh you don’t want on the bone for a clean bone presentation.   I was a bit lazy and left it on.  Set up a container with a lid, add some water and salt, combine it well, stirring up with a spoon.  Place bones into the container, cover and put in the refrigerator overnight.  It can sit in there two nights if you like, and you can roast them when you’re ready.  When taking them out of the water, rinse them off again.  If they are super white in color that means it’s clean.

Roasted Bone Marrow

Roasted Bone Marrow Recipe


1 to 2 lbs of Roasted bone marrow

saltwater cleaning overnight

kosher salt

ground black or white pepper

fresh thyme leaves

2 tablespoons unsalted butter


Preheat your oven to 425 degrees.

Step 1)  In a roasting pan, place the bone marrow up where you see the bone marrow filling.  Sprinkle them with kosher salt and pepper.  Then you can add some fresh thyme on top and slices of unsalted butter to the top and bottom of the roasting pan.  Put butter on the roasting pan to help brown the bottoms of the bone marrow and the top.

Step 2)  Place the roasted bone marrow pan into the oven and bake about 20 minutes.  When you take it out of the oven, the bone marrow should be very soft inside. You can check this by using a butter knife or fork.  Set it on the counter and let it cool.

Bacon Onion Jam

Bacon Onion Jam recipe


1 medium-size onion of your choice

2 tablespoons of unsalted butter

3 strips of bacon

2 tablespoon of brown sugar

1 tsp of balsamic vinegar glaze

pinch of salt and pepper

red wine (optional)


Step 1)  Peel and slice the onions as thin as you can get them.  It will caramelize faster and more evenly.

Step 2)  Heat frying pan on medium-high and toss in onions.  Cut up three strips of the bacon, it doesn’t matter what type just get some bacon bits into the pan for rendering the fat and adding flavor to the onion jam.

Step 3 ) Add two tablespoons of the unsalted butter and the thinly sliced onions. Turn the heat down to a low simmer. Allow it to caramelize. This could take up to 15 minutes or more. You’re looking for wilted brown onions. Stir it every so often so things don’t get burnt.  You can at this time add a little splash of red wine for some flavor but it’s optional.

Step 4 ) Once the onions and bacon become one and caramelized. Add some brown sugar, a pinch of salt and pepper. Then lastly you add some balsamic vinegar glaze.

Enjoying the roasted bone marrow at home with some toasted baguette.  I made my own bread but you can just buy it at the store and toast it yourself at home. When I made my first roasted bone marrow and onion bacon jam,  I didn’t want to pay for this at a restaurant anymore. Every bite was divine because  I did the work and reaped the rewards. It’s a fancy way to have lunch or a simple appetizer snack before dinner.
