Costco Carbonaut Bagels Review

Do you absolutely love bagels but are trying to limit your carb intake? The Costco Carbonaut Bagels are lower in carbs and calories and higher in fiber than regular bagels. They’re keto-certified, plant-based and gluten-free. How tasty can a bagel like this actually be though?

Bagels aren’t my absolute favorite bread item but I still like them! I’m more of a toast girl but I’d never say no to a bagel. During my husband’s last visit to Costco (we haven’t attempted taking the baby to Costco yet) he picked up these Carbonaut bagels for me to try and review!

The Carbonaut bagels are keto verified as well as gluten-free.

I’ve already reviewed both the white and multigrain Carbonaut bread from Costco. The Keto 1.0 All-In Bagels from Costco have high protein and fiber. If you’re someone who just wants a regular bagel you might like the Kirkland Signature Cinnamon Raisin Bagels, Kirkland Signature Imitation Blueberry Bagels, Kirkland Signature Jalapeno Cheddar Bagels, Kirkland Signature Everything Bagels or just the Kirkland Signature Plain Bagels.

Location in Store

You can find the Carbonaut Bagels in the bakery section at Costco, the item number is 1683305.


I can’t say I enjoy these. They’re not very flavorful, it’s kind of like eating salty dust or cardboard. They taste way better toasted than not and a lot of butter also enhances the flavor. I think if you’re used to eating gluten-free bread these actually might taste pretty okay.

The bagels have a bit of a powdery flavor.

The texture is a lot less dense and chewy than a typical bagel, the texture reminds me of the gluten-free hamburger buns I ate during my pregnancy. They need extra toasting to become crispy and as I said earlier, are very bland.

I think the bagels taste much better toasted.

Toasted it has a really light, airy, spongey odd texture, not like the nice texture you get with a normal bagel. I don’t notice the typical bitter aftertaste that I notice a lot of keto products have so that’s one bonus but they do have a bit of an odd powdery taste.

The texture of the bagels is quite light and spongey.

There is also a bit of a savory aftertaste I find it hard to explain, not bitter and not unpleasant.

The bag of 10 bagels costs $9.99 Canadian, so about a dollar per bagel which is pretty expensive. I think the cost is definitely related to the fact they’re low-carb, low-calorie and gluten-free.

There are two separate bags containing five bagels in the bigger bag. The best-before date is about ten days from when I purchased the bagels. You can freeze the bagels if you aren’t going to use them by the best-before date.

Carbonaut bagel product description from the bag.
The Carbonaut bagels are keto-certified, plant-based and gluten-free.

I definitely recommend having these toasted over not and to make them taste better I would slather some butter, nut butter or jam on them. Alternatively, I’d use them to make breakfast sandwiches,



One bagel is 70 calories, five grams of fat, 37 grams of carbohydrates, 35 grams of fiber, zero grams of sugar and 360 milligrams of sodium. The calories, fat, carbohydrates and sodium all aren’t that high! The fiber is extremely high though which is to offset the carbs.

If you have a sensitive tummy I’d be a bit wary about consuming that much fiber in a tiny bagel.

Carbonaut nutrition facts from the bag.
Nutrition facts.


The Costco Carbonaut bagels have a short and sweet ingredient list. Water is the first ingredient that I find really surprising. The bagels are gluten and dairy-free but contain some ingredients which are known to cause stomach upset such as inulin and psyllium. Also, I don’t think any of the ingredients are really nutritious so there are not a lot of nutritional benefits when eating these.

I will say that there aren’t any major allergens in the bagels like soy, wheat, dairy, eggs and they’re also sugar-free.

Carbonaut bagel ingredients list from bag.


Taste: 4/10

Cost: 6/10 (The price seems typical for a gluten-free, lower-carb product).

Convenience: 10/10

Nutrition: 3/10


Walk on by unless you’re used to gluten-free bread, then give it a try!

Overall these taste very slightly similar to a regular bagel. I think if you’re used to gluten-free bread or are trying to avoid all the major allergens you won’t mind these. If you just want a tasty bagel and don’t care about carbs or gluten, look elsewhere.

  1. Not worth the price for a gluey, crumbly and tasteless product. Will stick to you teeth and nearly impossible to slice unless frozen.

  2. I use the plain ones, toasted, and top them with cream cheese, sliced turkey and cucumber. It’s a good, low-carb alternative and very low in calories as well compared to regular bagels. They are very soft when not toasted and I agree they do tend to fall apart, I have to be careful when spreading toppings on them. These do not bother my tummy but I am used to a high fiber diet. I don’t mind the taste or the colour – really, it’s a gluten free, low carb bagel. Would you expect it to taste and look just like a regular bagel?

  3. These bagels are Delicious if you’ve never eaten anything! The dead flesh colour of the bagel, reminds me of eating a science experiment my 5 year old made. I was especially pleased when I picked up the bagel and it fell into 10 pieces on the plate. Mmmm I love future food from the Mars voyage.

  4. Hi. So happy to see the bagels in Costco! But, which locations? Canada or USA? I’m in NY and they don’t have it at my store. TIA

  5. Thanks for the review….I was wondering why the bagels tasted a little weird in comparison to other gf products that I have tried. I have tried both of the sliced bread brands available for sale at costco – little northern bakehouse and the other one of I can’t remember now, and both were pretty good. I have also tried superstore, whole foods, saveon, and safeway gf food items, from bread, cakes, hotdog buns, donuts, cookies, pie crusts, chips, corn flour wraps, pizza crusts etc. and all have been pretty good when comparing the items had they been made with flour. However the cabonaut gf, keto bagels, are kinda like when you don’t have anything else good to spread, butter, jam, peanut butter, cream cheese etc. on….. will do…maybe….if you don’t even have rice crackers….then…and only then…..will these be ok…

  6. When you have type1 diabetes every carb counts so with only 2 carbs per bagels I’m in! Haven’t be able to eat bread in so long therefore when I found the carbonaut bread I was thrilled. Will definitely get the bagels next visit!

  7. Just a couple of notes: you meant wary but used weary. Jam negates the point of a low carb bagel! Thanks for the review! I’d be interested in low carb, not gluten free bagels. 🙂

  8. The Carbonaut blueberry/lemon bagels are really good. I agree the plain are just that…plain. Hoping they get the blueberry ones in as well, specialty stores charge $10-11 for 5!
