Caramelized Onion, Blackberry, and Mascarpone Cheese Crostini
This is a delicious appetizer that takes a bit of work, mostly due to the caramelization of the onions. However, the flavor payoff it worth it! They are a bit high in carbohydrate so best for special occasions.

Ingredients
Caramelized onions
- 2 yellow onions sliced
- 1/4 cup butter or oil of choice, such as butter flavored coconut oil, if dairy-free
Crostini
- 1 keto bread recipe formed as a baguette and sliced thin into 16 slices
- olive oil or avocado oil for brushing
- 8 ounces mascarpone cheese or kite hill cream cheese if dairy-free
- 4 ounces fresh blackberries 16 berries, halved
Instructions
Make the caramelized onions
- Add the butter to a pan and, when warm, add the onion slices. Toss well to coat the onions in butter and cook, stirring occasionally over medium high heat. After softening, stir every 5 minutes as they caramelize, about 30 more minutes. Towards the end you may need to stir more often, and cook to desired color/caramelization, another 5-10 minutes. If things seem like they are burning or sticking too much, add a couple tablespoons of water to the pan and stir well. Set aside to cool.
Make the crostini
- Preheat the oven to 350ĀŗF. Slice bread thin and place on a rimmed baking sheet. Brush with oil and bake at 350ĀŗF for 10 minutes, or until crisp and golden. Set aside to cool.
To assemble
- Spread half a tablespoon of mascarpone on a crostini. Add a spoonful of caramelized onions and top with 4 blackberry halves.
