Keto Caramelized Onion + Rosemary Brie Bites

I’ve got the perfect low carb appetizer that you can serve at Thanksgiving, any holiday gathering or New Years!

These Keto Caramelized Onion + Rosemary Brie Bites are so simple to make and loved by everyone.

Keto Brie Cheese Appetizer

Here is why these adorable brie cheese bites are kind of the best keto appetizer ever:

  • I’m using Supreme Brie Bites (code TASTESLOVELY for 15% off $30+, expires 12/31/2020), which are individual brie bites. They have the thinnest rind, and the creamiest most delicious brie cheese.
  • The individual size makes these so easy to pick up and enjoy! No need for slicing.
  • These are amazing at room temperature, so no need to worry about keeping them warm or cold! So important for appetizers that you want to be able to place out and display for your guests to graze on.
  • You can prep the onion mixture ahead of time if you want to really cut down on cook time the day of your gathering.
  • It’s an appetizer that everyone loves, keto or not! Plus, meat free so vegetarians can enjoy too!

The onion mixture is made of caramelized onions, chopped pecans and fresh rosemary. So flavorful, and the yummiest way to take these brie bites to the next level. Tastes like the perfect holiday bite.

Feel free to use whatever nut you have on hand. Almonds, walnuts or pistachios would be great too! I be these would be just as delicious using fresh thyme as well.

5 from 2 ratings


  • 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.
