Costco Franz Keto Bread Review

One consistent trend I’ve noticed since I started this site is that there are always readers looking for good keto products. Some products are easier to make keto-friendly than others though! Bread is pretty much the definition of a carb-heavy food, so creating a keto version that tastes good isn’t easy. I reviewed the Carbonaut Keto Bread a couple of years ago and it was actually pretty good. Is this Franz Keto Bread a better option? Will it fool you into thinking you’re eating real bread?

Other keto products available at Costco are the Chocxo Dark Chocolate Coconut Cups, Carbonaut Bagels, Highkey Mini Cookies, Keto 1.0 All-In Bagels, No Sugar Company Keto Bars, Innofoods Keto Granola, Universal Bakery Keto Bites, Keto Skream Frozen Dessert Bars, Rao’s Marinara Sauce and the Ozery Bakery Seedwise Keto Clusters.

Location in Store

I found this by all the other breads at Costco in Kalispell, Montana. The item number is 1403314.

I’ll be honest – this bread isn’t great, even compared to other keto breads I’ve tried like the Carbonaut Bread. It’s plain and the bitterness you find in a lot of keto products is pretty strong. The flavor just isn’t very pleasant.

I used the keto bread to make a grilled cheese!

I tried making a grilled cheese sandwich with the bread and it definitely tasted better than when I tried it plain, but the keto bitterness was still a little too noticeable. I think there are better keto bread options out there.

The bread toasts up nicely.

I’ll admit that I’m not a big fan of white bread; I prefer multigrain and other breads like that. I don’t think that’s my problem with this bread though. I’ve had too many good keto products where the bitterness isn’t so pronounced.


The bag comes with two loaves of white keto bread and costs USD $8.99; that’s not bad for a keto product. Generally, I find anything labeled as “keto” costs more.

There are two single loaves of bread in the larger bag and the best-before date is about 14 days from when I purchased it. I always freeze my bread right away though, I never leave it sitting out.

The slices are decently thick which is surprising since there are so few calories in a slice!

If you’re on a keto or low-carb diet you can have this bread as a side with eggs and bacon, use it to make breakfast sandwiches, slather it with butter or pair it with your favorite sandwich toppings. I think keto products are a bit of an acquired taste so if you’re used to them, you may find this bread okay. I don’t think kids would enjoy them.

The Franz Keto Bread is a product of the USA.



One slice of bread contains only 35 calories, one gram of fat, 90 milligrams of sodium, 12 grams of carbohydrates, 11 grams of fiber, zero grams of sugar and four grams of protein.

No wonder it doesn’t taste good, with only 35 calories and one gram of fat! This is super low calorie and also has a decent amount of protein, four grams per slice!

Nutrition facts.


This is keto-friendly but not gluten-free. It’s also vegan and doesn’t contain any allergens like peanuts or tree nuts but does contain soy. I wouldn’t call this healthy or nutritious but you’re trading nutrition for low calories. If you’re craving bread for only a few calories and are used to keto products, this gets the job done.

Image of the ingredients list for the bread from the back of the bag.


Taste: 4/10

Cost: 6/10

Convenience: 10/10

Nutrition: 7/10 (Low calories and fats but lacking nutrients).


Walk on by!

I think there are better keto bread options out there (such as the Carbonaut Keto Bread). However, if you’re looking for a super low-calorie bread that’s also keto, you don’t have a ton of options and this Franz Keto Bread might be worth trying.

If you use it in a sandwich or something, your other ingredients might cover up the taste of the bread enough that you can just kind of forget it’s there.

Have you tried this Franz Keto Bread? What did you think of it?

  1. I ate Aunt Millie’s Live Carb Smart for a long time. It’s pretty close to the real thing. Then I found Aldi had a zero carb bread and that’s what I tend to use now. Both are really good for Keto breads.

  2. This Keto bread has Soybean oil & hydrogenated soybean oil which both are very inflammatory to the body. Modified wheat starch(not Keto unless the starch is resistant). This bread isn’t Keto. So many Keto products aren’t Keto. It’s all in the ingredients.

  3. I have tried this keto bread and totally agree that it is a walk on by. I do have to admit I am not a big bread fan except for good sour dough but this keto bread is just nasty
