Ingredients

  • 5 pounds large beef marrow bones
  • 1 pound unsalted butter room temperature
  • ¼ cup water room temperature
  • 1 tablespoon fresh thyme leaves chopped
  • 1 tablespoons fresh rosemary leaves chopped
  • 1 teaspoon salt
  • Sprigs of fresh herbs for garnish

Instructions

  • Preheat the oven to 400°F 
  • Place the bones on a rimmed baking sheet and roast until the marrow is bubbly and light brown, about 20-25 minutes. 
  • Transfer from the oven and cool until you can handle them.
  • With a butter knife, or appetizer spoon, scrape the marrow into a small bowl.  Set aside to cool to room temperature.
  • Add the butter to the bowl of a stand mixer with the whisk attachment, (or a handheld electric mixer) and whip on high speed until light, fluffy and pale in color, about 8-10 minutes. With the mixer running, slowly drizzle in the water then add the cooled marrow, thyme, rosemary and salt.  Continue to whip for another 30 seconds to fully combine.  
  • Transfer the spread to as small dish and serve.  

Notes

  • The ratio of butter to marrow should be 2:1. If you have less in the bones, reduce the amount of butter to equal the 2:1 ratio.
  • You can serve this spread with crackers, toast points, bread slices, dolloped on grilled steaks, or as part of a charcuterie board.
  • This recipe makes about 5 cups of butter and will make a nice hostess gift in a small glass jar tied with a ribbon.
  • Store in the refrigerator in a covered container for up to 2 months.
