Why You’ll Love Onion & Mushroom Baked Brie

You know I love brie, and this one has to be one of the best ones I have made this far! The truffled caramelized onions give it the best taste… I used Truffle Black Salt by Truff! It’s creamy, earthy and perfect! It is very easy to make, and perfect for hosting and serving as an appetizer!


I topped with chives, but you can easily swap them for your favorite herbs. I used enoki and shiitake mushrooms, but you can use your favorite mushrooms.

  • Slice your onion in half, and then in half again. Cut into thin slices
  • Preheat a pan for 2 min on medium. Drizzle a bit of olive oil and add in the onions
  • Sautee on medium for 5 min and add in the mushrooms. Lower heat to medium low and let them caramelize for 20-25 min, mixing periodically.
  • Add in the butter and truffle salt to taste. Mix it in. Let them fully caramelize, should be another 25-30 min. Deglaze with the balsamic and cook together for 2-3 minutes
  • Using a knife, cut a circle on top of the brie. Bake at 400F for 15 min
  • Toast the almonds in a pan until golden brown
