Kirkland Organic Peanut Butter


Costco Peanut Butter Kirkland Organic

Kirkland Signature, the in-house brand of the multinational corporation Costco, is widely known for offering high-quality products across an extensive range of categories.

As such, it should come as no surprise that their Kirkland Signature Organic Peanut Butter is no exception. This peanut butter is so good it keeps me paying for a Costco Membership.

Kirkland Peanut Butter Taste

The primary determinant of a good peanut butter, quite naturally, is its taste. Kirkland Signature Organic Peanut Butter impresses on this front with its rich, robust flavor that boasts a near-perfect balance between sweet and salty. It captures the essence of peanuts in its purest form. The taste is not overly intense, nor is it too subtle; it hits the sweet spot in between, making it a versatile addition to your pantry.

One of the highlights of this peanut butter is its organic nature. Made with just two simple ingredients – dry roasted organic peanuts and sea salt – this peanut butter is free from any artificial sweeteners, flavors, or preservatives. This clean, minimalist approach is reflected in its natural, authentic taste that peanut butter purists will absolutely relish.

Costco Organic Peanut Butter Texture

In terms of texture, Kirkland Signature Organic Peanut Butter is smooth and creamy, not graininess in my experience. Like any peanut butter that contains only peanuts and salt it will separate and need to be stirred before use.

The best way to use this peanut butter is to stir it very well when you first open it making sure to mix all the way to the bottom and then store it in the fridge. At the cooler temperature the oil will solidify enough to stop separation but not enough to make it hard.

From the fridge it’s smooth and easily spreadable, making it an ideal choice for sandwiches, smoothies, and a variety of other culinary applications.

Kirkland Organic Peanut Butter Nutrition

With its organic ingredients and lack of artificial additives, Kirkland Signature Organic Peanut Butter is as healthy as it is tasty.

Each serving contains 8 grams of protein, making it a good source of plant-based protein. It also offers a decent amount of fiber and a dose of fat from the peanuts.

While it’s not low-calorie food (which peanut butter generally isn’t), the nutrition it provides, combined with the absence of harmful additives, makes it a sensible choice for those looking to balance taste with health.

Size and Packaging

The peanut butter comes in a 2-pack of 28-ounce jars, a generous size that is enough to last a while, even for frequent users. The jar is designed with simplicity in mind, bearing a clear label that showcases the product’s organic certification and the signature Kirkland branding. The jar itself is easy to open and close, ensuring your peanut butter remains fresh after each use.

Value for Money

As is common with Kirkland Signature products, this organic peanut butter offers great value for money, retailing at $12.99 for two 28-ounce pack (or $0.23 per ounce) on Frequently, you can find better prices in-store since the online price includes shipping. My local Costco sells it for $10.99 (2023) per 2-pack and I don’t see it go on sale often.

Costco Organic Creamy Peanut Butter

The cost per ounce is very competitive when compared with other organic peanut butters on the market. For comparison, similar organic product sells for around $14.86 for 16-ounce (or $0.93 per ounce) on Amazon. If organic isn’t a must, you can find Skippy peanut butter products for cheaper at $11.99 for two 48-ounce pack (or $0.12 per ounce).


Kirkland Signature Organic Peanut Butter is an exceptional product that does justice to the brand’s reputation for quality and value. It’s a pure, organic peanut butter with a delightful taste, an appealing texture, and a good nutritional profile.

Whether you’re a peanut butter connoisseur or someone looking for a healthier alternative, this product deserves a spot on your shopping list. Kirkland has indeed struck the perfect balance between taste, health, and value with their organic peanut butter. This is my family’s go-to product when it comes to peanut butter.

The Best Natural Peanut Butter for the price!

September 23, 2023

While I haven’t tried the more expensive fancy peanut butters I don’t expect them to be that much better that Costco’s Kirkland Organic Peanut Butter. The ingredients are just peanuts and salt and that is what I am looking for in a peanut butter!
