  • 2 tablespoons grass-fed butter divided
  • 1 small yellow onion sliced
  • 1/4 teaspoon kosher salt
  • 1/4 cup chopped roasted pecans
  • 2 tablespoons finely chopped fresh rosemary
  • 10 brie bites room temperature


  • Heat your cast iron skillet over medium heat. Add 1 tablespoon of the butter, sliced onions and 1/4 teaspoon kosher salt. Cook until the onions are soft and caramelized, stirring occasionally. Should take around 15-20 minutes. I like to add in a few tablespoons of water every 5 minutes to keep the onions juicy and prevent them from burning.
  • Add in the remaining tablespoon of butter, chopped pecans and rosemary. Stir and cook until fragrant, just a minute or so.
  • Place the room temperature brie bites onto a cheese board. Top each brie bite with the onion mixture. Serve at room temperature.



Onion: I used a yellow onion, but you could use a red or white onion, or even shallots!
Nuts: I love pecans, but you could use chopped walnuts, almonds, pistachios, etc.
Herbs: I love rosemary, but thyme would work too.
