Blueberry Gratin

The easiest low carb dessert you’ll ever make! This BLUEBERRY GRATIN calls for just three ingredients and it’s ready in less than five minutes. What are you waiting for? 

Blueberry gratin recipe

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!

  1. Hi Karly, someone asked how large your ramekin was….you weren’t sure. If you would pour water into the ramekin you used, then pour that water into a measuring cup, that would tell us how large it is.

    1. Karly Campbell

      Hi Sue! It doesn’t matter what size ramekin you use, so long as it fits 1/4 cup of blueberries and 2 tablespoons of sour cream spooned on top. It won’t hurt anything to use a larger one. You could even bake all this together in a small baking dish and then portion it out after baking. 🙂

  2. susan purdy

    HI, what is the size of the ramekin? I know you said small, but could you say how many ozs. of blueberries? TIA

    1. Karly Campbell

      Hi Susan! I’m not sure how many ounces my ramekins hold – I have a few different sizes that I’ve used either way. I didn’t weigh the blueberries, just divided them between the ramekins.

  3. lizzie barron

    i have been doing keto for months & my weight loss is so slow- i have thyroid disease & take meds for something else that causes weight gain- so it’s an uphill battle
    i’m an oh boomer so not into blogging but i came upon ur blog & your recipes look great! u don’t use artificial sweetener s & the recipes look simple with good ingredients so i’m going to try some- i’m excited to have found u!

    1. Karly Campbell

      Thanks, Lizzie! Hang in there on keto…everyone loses at different rates, but I really believe it’ll work if you stick it out. 🙂

  4. Brenda J Anderson

    I would love to make this. How can you tell if your ramekins can go under the broiler?

    1. Karly Campbell

      It would be on the packaging when you buy them. It may say on the bottom of the dish as well.

  5. Best quick dessert EVER! Used frozen blue berries with great results. You would never know the topping is sour cream.

  6. Kathleen Wright

    This was the simplest, most delicious dessert I’ve had in a long time. The blackberries were perfect and the Swerve brown sugar caramelized to a delicate crunch of just the right sweetness on top of the sour cream. With the nutritional numbers as they are, I might be having this a lot. Funny thing is, I sat down for ten minutes before dinner to do a quick check of email and “bing” there was your recipe in my inbox. I had all the ingredients on hand so it was a nice surprise for both me and the hubs after a long day at work. Thanks SO much!

    1. Karly Campbell

      Yay! I’m so glad you gave this a try! I feel like so many people think it sounds weird and don’t give it a shot and it’s SO GOOD! 🙂 Thanks for sharing!

  7. Whaaat??? It’s really that simple? I’ve got to try this tonight! I love sour cream but the Hubs does not. Wonder if he’ll be able to tell….either way, I think I’ll be eating blueberries for the first time in five months! Win, win! Thanks for sharing!

    1. Karly Campbell

      Hope you and hubs both loved this one! You could try yogurt on his portion maybe? I haven’t tried it with yogurt, so might get funky in the oven but I’m not sure. 🙂

      1. Karly! He never even suspected anything other than a creamy custard Ü Tee hee! It was so fast and super rich and yummy! Luvin’ That Low Carb Life ♥ Thanks again!
