    You can be low carb and still enjoy holiday appetizers! These Keto Cheese and Onion Pinwheels taste JUST like the puff pastry finger food that inspired them!

    A couple weeks ago, I posted my recipe for Cheese and Mushroom Pinwheels... and now it’s time for the companion recipe.

    As I mentioned in that post, I used to love buying the President’s Choice Cheese Hors D’Oeuvres box during the winter holiday season.

    It had 4 or 5 different kinds of cheese filled puff pastry bites - I ended up replicating those fillings in my Puff Pastry Pinwheels recipe a few years ago.

    Anyway, the cheese and mushroom pastries and the cheese and onion pastries were both FAR and away my favourites.

    After my body decided that gluten and carbs were the enemy, obviously I had to come up with a low carb version for that holiday tradition!

    This recipe uses fathead dough as a stand-in for puff pastry sheets - it works incredibly well!

    Speaking of incredible, this filling is an incredibly accurate replica of the beloved source material, and absolutely scratches that itch. In NO way do these pinwheels feel like diet food, and no one is going to miss the wheat or carbs!

    On that note... while these are individually keto friendly, they’re also the kind of thing that you can inhale a plate of EASILY. Just keep in mind that they’re less keto when eaten in *volume*, LOL.

    Anyway, they work out to 2 grams net carbs per pastry.

    Let’s take a look at what you’ll need to have on hand, to make a batch for yourself.

    Ingredients

    This recipe uses really basic ingredients - you shouldn’t have any trouble finding everything you need, in pretty much any larger grocery store.

    As always, I have a few ingredient notes for you:

    Super Fine Almond Flour - Look for “super fine” specifically - it’s not the same as “almond meal”, which will give your dough a grainy texture.

    Shredded Mozzarella - I like using pre-shredded “Pizza Mozzarella”.

    Cream Cheese - Use full-fat cream cheese. Lower fat ones would probably work, but tend to be carbier.

    Small Onion - I’ll usually use a yellow onion, but you can really use whatever kind you like / have on hand.

    Everything Else

    Rounding out this recipe, you will need:

    Shredded Cheddar Cheese
    Shredded Parmesan Cheese
    Large Eggs
    Dijon Mustard
    Dried Parsley
    Baking Powder
    Xanthan Gum
    Smoked Paprika
    Ground Black Pepper
    Salt

    ... I just don’t have anything else to add, as far as these last few ingredients go!

    How to Make Keto Cheese and Onion Pinwheels

    The full recipe is in the printable recipe card at the end of this post, here is the pictorial walk through:

    Cheese & Onion Pinwheel Filling

    In a food processor, blitz cream cheese, chopped onions, and mustard until well combined and smooth.

    In a separate bowl, combine the cheeses, parsley, xanthan gum, and smoked paprika.

    Add the cheese mixture to the food processor, blitz until well combined and smooth.

    Season with salt and pepper, to taste. Cover and chill until use.

    Keto Pastry Dough

    Measure mozzarella cheese into a microwave-safe bowl. Heat - 30-45 seconds at a time - until cheese has melted.

    2 part image showing a bowl of mozzarella and cream cheese before and after melting and being mixed together.

    Measure remaining ingredients into a food processor - except the eggs - blitz to combine. Add the eggs, blitz once more to fully combine.

    Add melted cheese to the food processor, pulse until well combined - you don’t want to see any sections of unmixed cheese.

    5 part image showing the dry ingredients being blended with egg, then the melted cheese mixture added and mixed in.

    Using wet hands, gently knead the dough to form a smooth ball.

    Assembly

    Divide the dough into 2 equal sized balls, wrap one in plastic wrap and set aside for now.

    Roll the other ball of pastry dough out between sheets of parchment paper, aiming to make it a rectangle about 8" x 12".

    Spoon half of the filling onto the pastry sheet. Spread in an even layer, leaving a 1" strip along one long side of the pastry.

    5 part image showing fathead dough being rolled into a rectangle and spread with cheese and onion mixture.

    Starting with the edge across from the bare strip, roll the pastry up - towards the bare end.

    Continue rolling, gently pressing the bare strip against the main roll to seal it.

    Repeat with remaining dough and filling.

    Wrap each roll with plastic wrap, chill for 30 minutes.

    Preheat oven to 400 F, line 2 large baking sheets with parchment paper.

    Once thoroughly chilled, use a sharp knife to cut each roll into 12 even slices.

    4 part image showing a chilled pastry roll being scored and cut into 12 rounds.

    Arrange cut spirals on the parchment lined baking sheets, leaving 2" between the pieces.

    Bake for 15 minutes, or until golden brown, puffed, and cooked through.

    Remove from oven, allow to cool slightly before serving.

    To Freeze for Future Use

    Once raw pastry rolls are cut, arrange in a single layer on parchment lined baking sheets. Cover and freeze until frozen through, usually a couple of hours.

    Once frozen, transfer pieces to labeled freezer baggies. Remove as much air as possible - ideally vacuum seal them - and return to the freezer for up to 6 months or so.

    To Bake from Frozen

    Preheat oven to 400 F. Arrange frozen pastry pinwheels on parchment lined baking sheets, bake for 20-22 minutes or so, until golden brown, puffed, and cooked through.

    To Air Fry from Frozen

    Preheat air fryer to 375, cook for 10 minutes or so, or until golden brown, puffed, and cooked through.
