The first time I heard of a berry gratin, I was super confused.

In my mind, gratin means cheesy covered taters and, well, that doesn’t go well with blueberries, you guys.

I’m happy to report that dessert gratin is totally different than potatoes au gratin (or, even better, turnips au gratin). Not only is this blueberry gratin EASIER, it’s also, well, dessert – and who can complain about that?

I hope you give this one a try – I think you’re going to love it!

How to make a low carb dessert in less than 5 minutes:

Grab a couple of ramekins. Fill them with blueberries.

Spoon some sour cream over the top. <— I know this sounds a little weird, but trust me.

Sprinkle with some Golden Monkfruit (affiliate). I love this stuff because it tastes a lot like brown sugar, doesn’t have any funky aftertaste, and it’s all natural and keto friendly.

Pop the ramekins on a baking sheet and then stick that whole thing under your broiler for a couple of minutes.

This will warm the sour cream and berries slightly while caramelizing the monkfruit. 

You end up with this crackly top, creamy center, and juicy berries.

And, if you’re not a fan of blueberries, you can definitely make this with whatever berry you like. I’m partial to raspberries myself! 

That’s it, friends! Quick, simple, and it looks and feels a little fancy. Definitely one to try!

We serve this for dessert, but if you’re a fan of yogurt for breakfast, you might try this one for breakfast instead! It’s delicious!
