You'll love these homemade cheese puffs - they're a great Keto popcorn alternative! All you need is cheese - and a bit of patience. A super easy low carb snack idea.
This is not much of a recipe, as it only contains one ingredient - cheese. Nevertheless, it's a snack I like to make regularly, and I love to think of it as my "Keto popcorn".
Full disclosure here - I do eat a bit of "real" popcorn now and then. My daughter has a popcorn machine, which she puts to use for movie night. We like our corn well-buttered and salted.
Can you eat popcorn on a low carb diet?
In the scheme of things, maize popcorn is not the worst choice of snack. One cup of air-popped corn contains just under 5 net carbs, which is fairly low. The issue, of course, is the amount. A typical serving of popcorn is 24 grams (3 cups) and contains 18 grams of carbs and 4 grams of fibre. And we all know what happens once you get started on a bowl of popcorn... life happens.
How to make Keto popcorn
1.) You can make these cute little cheese puffs with different types of cheeses and using different methods. I used parmesan and two different types of cheddar.
PARMESAN.
On the left in the image above. I blitzed it in the food processor. I then used a sieve to separate the smaller bits and only used the larger ones. (The small bits can be used for your next Italian cooking session).
MATURE CHEDDAR.
Top right in the image. Using my hands, I crumbled a block of cheddar. This way, you get rounded pieces (pop-corny even before popping!) that are more equally sized. It is a little salty, which means you're satisfied quickly. It's my personal fave.
MILD PRE-SLICED CHEDDAR.
On the grey plate. This delivers airy bubbles and does not taste of much. I normally don't buy this kind of cheese, because I find it quite bland. It's a bit of a faff slicing it into tiny squares. But it's the closest experience to eating real popcorn.
2.) Depending on the amount of space you have at home, you can either put your sliced / crumbled cheese on a plate or directly on the parchment-covered baking tray you'll eventually bake it on.
Cover it with a kitchen towel or muslin (so it does not gather dust) and leave it in a dry, warm place for 3 days so it drys out COMPLETELY. Your Keto popcorn will only pop if it's totally dry and hard. If it's not, it will just melt. Still yum, but not what we're after here.
3.) After 3 days (if your cheese was dry to begin with, you might get away with 2 days) heat your oven to 200 Celsius / 390 Fahrenheit and bake the cheese for 4-5 minutes. To prevent the pieces popping all over the place, place a second baking tray above your cheese tray.
This low carb popcorn substitute is super crunchy and crispy and I think it makes a VERY satisfying snack. Experiment with different cheeses and find your personal favourite!
Here are some other savoury low carb and Keto snacks we like:
Veggies and veggie sticks (celery, fennel, peppers, carrots, radishes, cauliflower florets) with dips
Low Carb Pizza Bites - like pizza, but without the carbs
Slices of raw sweet potato (whilst the potato is uncooked, the majority of the carbs are resistant starches and not absorbed) with cream cheese / almond butter
Genius Grain Free Pretzels - made with Fathead dough
Olives
Nuts and seeds (you can roast them with a little olive oil and spices or herbs such as cumin, paprika, garlic salt, rosemary, thyme
Kale chips - the only way my children will eat kale. They love it (and I do too). Find the recipe here.
Paleo Almond Low Carb Crackers
Ham rollups - ham filled with cucumber, cream cheese or mashed avocado. Or use nori seaweed sheets instead.
I could go on, but think this list is long enough. And I did not even get started on the sweet snacks! 🙂
Store your Keto popcorn in an airtight container in the fridge for up to a week. It's not only great as a snack - you can also sprinkle it on soups or over salads.

Keto Popcorn - Puffed Cheese
from Sugar Free LondonerNote: The servings slider only changes the first amount in each line and not any subsequent amounts. Please make your own calculations where necessary. ***As an Amazon Associate I earn from qualifying purchases.
Ingredients
- 3.5 oz / 100g cheddar
Instructions
- If you use sliced cheddar, cut it into 0.5 inch / 1 cm squares. If you are using a cheddar block, crumble it with your hands to the same size.
- Cover the cheese with a muslin / kitchen towel to prevent it getting dusty and let it sit in a warm, dry place for up to 3 days. You want the cheese to be completely hard and dry.
- Heat your oven to 200 Celsius / 390 Fahrenheit. Scatter the cheese on a baking tray lined with parchment paper and bake for 4-5 minutes until the cheese pops. To prevent it from popping all over your oven, place a second baking tray closely above the tray.

Susan says
I would love to see a video of this. I am having trouble understanding how to place the upper baking sheet. If the two baking sheets are identical, won't it form a cover just like the aluminum foil did that did not work? Sounds delicious, but I don't want a blob of little gooey cheese pieces lol.
Katrin Nürnberger says
Hi Susan, just put the top baking sheet on a higher rack. That way, if a cheese pops it won't jump all around the oven, making the oven itself greasy.
Beth says
WOW!!! I was finally able to make them this morning before work - and just got home from work and tried one. Wow, is really all I can say. I used sharp slices and my immediate thought when I tasted them was, "Cheez-its!" Granted it has been 6 years or more since I have had those crackers since I have been gf for 6 years, but these absolutely tasted like what I remember them to taste like, without all of the sodium. Thanks! Will be doing these regularly!
Gina says
Excited to try this. My cheese is almost ready for popping. Here goes nothing! I’ll let you know.
Katrin Nürnberger says
Can't wait!
Stacy says
Could I use a dehydrator first ?? I don’t feel comfortable with leaving cheese out for 3 days
Katrin Nürnberger says
Hi Stacy, I have never tried using a dehydrator, but it should work.
Emila says
I tried these. Loved it. These were so fun to watch them pop. I use this website all the time and have never been disappointed. Thanks Katrin!
Alessandra says
Ohhh I tried and didn’t work
I used pre-sliced mature cheddar, let it dry for 3 days but it didn’t pop nor melt, it just got burnt!
There was a lot of fat on the cheese bites sweating during drying, should I have wiped it off? Also, I don’t have two baking trays of similar size so I covered the tray with aluminium foil (pierced in several places). Do you think any of the two above might have been the reason? I’m not giving up, will try again!
Katrin Nürnberger says
I think wiping off the oil is a good idea, but should not really make a difference. But covering the cheese with foil during baking is probably what prevented it from popping. It lowers the temperature (I do this when I want to stop things from browning too much, such as bread or cakes) and also the air circulation. Try without next time, it should work a lot better.
Alessandra says
Hi! do you think this would work also with vegan cheese, either nut or tofu based? I'm tempted to give it a shot - unless you already know that it would not work 🙂
thanks!
Katrin Nürnberger says
Hi Allessandra, I have never tried that. It would be an experiment... who knows, maybe it works even better???
Alison Orr says
Wow, thanks for this! I’ve only just tried a shop bought version of this which I loved and wished I knew how to make it myself, as the ones on sale are expensive. Et voilà! Thank you!!
Katrin Nürnberger says
Glad you found my site! 🙂
Sara says
I second that!
Eating a pack of it now (just started keto, so my cravings are real!!!)
And was thinking ohhhh could I make these???
Thanks!
Cal says
I am sitting here wondering if you could use a cheese say with chives in it?, for a different taste or a smokey cheese?
Katrin Nürnberger says
Yes, why not! Sounds like a great idea
Shelby says
What brand of cheese did you use? Excited to try this!
Katrin Nürnberger says
I used the Sainsbury's own brand sliced cheddar. But any cheddar will work.
Kathleen stark says
Looks yummy I’m going to try it
Katrin Nürnberger says
Let me know what you think of it when you do Kathleen!
tina stover says
I used a chopper very small cub/dic e let it dry hard for a week it didn't work 🙁
Katrin says
How disappointing -so sorry to hear that. Which part did not work? Did the cheese not pop? Which cheese did you use?
Leigh Ann says
I'm thinking this would be great to do in a air fryer. Have you tried it in one?
Katrin says
No, I have not yet. It could work. The only thing I'm thinking - my air fryer has a heating coil at the top. When the cheese starts popping, some of them dance around a bit. In the oven, I put another baking tray on top to prevent the pieces go all over the place. The cheese bits may dirty the top of the air fryer. DOn't know if all air fryers look the same, but mine would be difficult to clean
Melissa says
Wouldn’t leaving the cheese out in a warm place invite some bacteria to come hang out?
Katrin says
I think that's a personal choice you need to make - whether you're comfortable with that. When you buy cheesy crackers in the supermarket, would you store those in the fridge? Personally, I think cheese can handle it. Plus, you're blitzing it in the oven at a high temperature.
whisperingsage says
Get a good book on homemade cheese and its history. Cheese normally is left in a cool place but not as cold as the fridge, for example caves in certain areas give the bacteria that make certain cheeses what they are famous for. Other cheeses are better at room temperature and in fact do their best flavors by aging at room temperature.
Paula says
Remember Friendship Bread? (definitely NOT Keto, but Google it!)
Starter batter sits on the counter unrefrigerated. Not all Bacteria is bad!
Maria says
I have tried these before, but they always just melted. Decided to give it one more go and with your tips it worked out! Thank you for all your hard work, I have tried many of your recipes and love them.
Katrin says
I'm so glad you enjoy my website Maria!
Barbara says
Such a brilliant idea! I used sliced Monterey Jack and it puffed up like a dream. Great Keto snack
Dorothy says
Have you tried this no a a dehydrator?
Katrin says
I don't have a dehydrator - it's on my wish list!!! If it can be set to a temperature that's cool enough for the cheese not to melt, it would definitely shorten the time needed to dry out. If you give it a go, will you circle back and let us know how long it took?
