Ingredients
  

  • ½ cup unsalted butter, softened to room temperature
  • 2 Tablespoons fresh rosemary, finely chopped
  • 1 teaspoon onion powder
  • ¼ teaspoon fine sea salt
  • ½ teaspoon lemon zest

Instructions
 

  • In a bowl, mix the softened butter with finely chopped rosemary, onion powder, salt, and lemon zest until it’s creamy and well-combined.
  • To store, spread the mixed butter in an airtight container. Or scrape the butter onto parchment paper and shape it into a log, then wrap it in the parchment paper. Store in the fridge.

Notes

  • Rosemary: I recommend using fresh rosemary for the best flavor. If you can only find dried rosemary, you can add that in, but I recommend letting your mixed butter sit at room temperature or in the fridge for a while before using it, so the crunchy dried rosemary pieces can soften a bit.
  • Lemon: Just a little lemon zest sends the flavor of this rosemary butter over the edge! I tried adding lemon juice as well, but that overpowered the rosemary and made the butter more likely to curdle.
