How to Make Keto Caramelized Onion and Brie Tart  

mozzerella and cream cheese

In a microwave-safe bowl, combine the cream cheese and mozzarella cheese. Heat for 30 seconds at a time until melted into a dough. 

Add the cheese dough to a mixing bowl with the almond flour, baking powder, xanthan gum, dried basil, salt, garlic powder, and egg. Knead until combined into a thick dough. Chill the dough for 30 minutes. 

While the dough is chilling, melt the butter in a skillet over medium-low heat. 

Add the onions, and saute until softened and caramelized. Remove, and let cool a bit. 

Roll the chilled dough out between two pieces of parchment paper until about ¼ of an inch thick. 

Line a baking sheet with parchment paper, and heat the oven to 350 degrees. 

Cut the dough into 8 evenly sized rectangles. 

Fold the edges of each rectangle up slightly. 

Top each rectangle of dough with some brie, caramelized onions, and fresh thyme and rosemary. 

Bake for 15 minutes.

Now, doesn’t that sound easy? You can bet that anyone that enjoys these tarts aren’t going to believe that you spent such a short amount of time on them!

What is The Difference Between a Tart and a Pie?

Many people believe that pies and tarts are the same things. They are not. While they are similar in that they both have a pastry crust on the outside, however, a pie can have a pastry top as well and a tart does not. Additionally, the pastry crust on a pie can often be crispier than a tart, which has a more simple type of crust. 

Another similarity between the two is that they can both be either savory or sweet. Thanks to this you can enjoy them for breakfast, dinner, or dessert!

Are Tarts Okay to Eat on Keto?

Most tarts are not keto-friendly, so be sure to not expect them all to be. These particular tarts have an almond flour-based crust which keeps the carb count low making them keto-friendly. 

So, if you have found yourself avoiding foods with a “crust” since you have been following a keto lifestyle, it’s time to enjoy crust again! 

Should These Onion and Brie Tarts Be Eaten Hot or Cold?

You can actually eat these tarts hot or cold, your choice. However, I have found that they are perfect when you take them out of the oven and let them cook for a short amount of time. They will be warm, but not hot and the melty goodness will not yet have gone away due to them being cold. 

Can You Make Any Alterations to This Caramelized Onion and Brie Keto Tarts Recipe?

Feel free to mix up the flavors of this tart recipe, as long as you keep it keto-friendly. If you aren’t a basil fan, cut that out, if you want to add more garlic, feel free! 

Do not be tempted to use puff pasty with these tarts though because they would then not be keto-friendly. 

People may wonder if they can substitute another flour for almond flour, but I would definitely say no. The almond flour is what makes the crust work on these. Other keto-friendly flowers just will not work the same. 

Are Keto Tarts Good to Serve for Parties?

These appetizers are as gorgeous as they are delicious and they really do make a wonderful addition to any celebration. They are great for serving at parties of all kinds. 

You certainly do not need any special occasion to make them though, they are easy enough to make for any weeknight meal.
