This roasted bone marrow butter- just like any other type of compound butter- is easy to make.

It’s similar to our Garlic Herb Butter in the fact that it’s studded with sea salt and fresh herbs. But the extra addition of roasted bone marrow takes the flavor up a notch to create a wonderfully beefy, umami-packed butter with a velvety texture.

It’s a gourmet compound butter that you can enjoy in so many different ways!

Bone marrow is high in healthy fats which is what gives it a rich flavor. It is most commonly described as a strong umami flavor which is why this condiment works so well as a main ingredient, but also spread onto a juicy steak.

Top a filet mignon, juicy ribeye or served alongside these tender steak bites for an incredible steak dinner that will rival any fine dining experience (truly our favorite way to enjoy it!). 

This creamy spread is also incredible served as an appetizer with hot toast and roasted garlic cloves or your own favorite crackers (like our sourdough discard crackers or our gluten-free artisan crackers). 

Why This Bone Marrow Butter Recipe Works

​Why go with ho-hum regular butter when this gourmet delight is an option? With just a few ingredients and a little bit of time, you can create an upscale, gourmet-inspired compound butter with so much flavor! And bonus… it is perfectly compatible with a paleo diet.

Here are all the reasons why you’ll love this spread:

  • Full of flavor. ​Bone marrow is naturally high in fat and we all know fat = flavor. Add it to creamy butter with a mix of fresh herbs for the ultimate treat for your taste buds!
  • Versatility. Stir a bit of this roasted bone marrow butter into soups or cooked vegetables for a big boost of yum. Top your steaks or homemade bread slices for an elevated main course or starter.
  • Easy to prepare. While recipes like this carry a high price tag at any fine dinning establishment, it’s actually quite simple and affordable to prepare at home. Like any recipe for compound butter, just a few ingredients and a little time is all you need to create this tasty butter mixture.

Ingredients Needed for Butter with Marrow Bones

Here’s a look at what you will need to make this gourmet delight.

  • Beef marrow bones. You can use a few different types of beef bone marrow bones as long as they’re large. The femur bones, tibia and shank bones carry the most bone marrow and all of these options should be easy to find at your local grocery store. 
  • Unsalted butter. ​Make sure it’s at room temperature so it’s easy to mix. 
  • Water. ​Also at room temperature so it blends well with the other ingredients. 
  • Fresh herbs. You will need a mix of fresh thyme and fresh rosemary, finely chopped, plus a few extra sprigs to use as an optional garnish. 
  • Salt. No compound butter is ready without it! Salt adds the perfect amount of flavor to this creamy, rich spread. You are welcome to add a pinch of pepper as well.
