Top Gluten-Free Products at Costco: Reviewed and Approved

Since my diagnosis of celiac disease in 2006, discovering appealing gluten-free options has often felt like a daunting task. It was not unusual for me to call customer service numbers on food packaging just to confirm whether a product was safe to eat. Fortunately, I’ve since honed my skills to identify hidden gluten, thanks to evolving labeling regulations. Nowadays, shopping for gluten-free food at Costco is far more convenient and delicious, whether gluten avoidance is a medical necessity or a personal choice.

At the end of this article, you’ll find a methodology detailing how I selected the best gluten-free items at Costco based on customer reviews. My focus was on products that received hundreds of 4-star and 5-star ratings, ensuring that each one is clearly labeled as gluten-free. These selections range from pizza and quick breakfast options to noodles and snacks, standing out for their quality, taste, and general appeal.

Gluten-free flours come in various types, including rice, sorghum, millet, corn, and almond. Almond flour is particularly favored for adding a nutty flavor to cakes, cookies, and breads.

Kirkland Signature Almond Flour has garnered a loyal following, boasting 428 reviews and an impressive 4.9-star rating on Costco’s website. A satisfied customer remarked, “I tried this brand for a gluten-free, wheat-free, grain-free option, and it’s the best flour I’ve ever used. It works wonderfully in every baking and cooking recipe.” Another reviewer recommends it for breakfast, stating, “This is my go-to almond flour for all my gluten-free baked goods and morning pancakes.” Additionally, one user claims it yields perfect keto brownies by substituting coconut sugar for regular sugar.

Malik from Baking Subs has compared multiple almond flours and prefers Kirkland Signature for recipes like banana bread and cookies. He also commended its affordable price, which is a considerable advantage as gluten-free items typically come with a higher price tag.

Being a fan of peanut butter and chocolate, I was drawn to the reviews for the G2G Peanut Butter Coconut Chocolate Protein Bars. Each bar offers 18 grams of protein and holds a 4.8-star rating with 449 reviews on Costco’s site, along with over 600 5-star ratings on the brand’s website.

One Costco shopper commented, “These are fantastic! I took a chance on 24 bars I had never tried, but they hit the spot. Great taste and texture—drier and crumbly, but not off-putting. I appreciate that they aren’t coated in a layer of chocolate.” A G2G website reviewer added, “I’ve kept these on subscription year-round; they’re one of the only protein bars that taste good and don’t upset my stomach.” Another admirer praised their clean ingredients: “This is my favorite protein bar. No artificial sweeteners, monk fruit, stevia, or sugar alcohols.” On Instagram, a user shared a taste test and declared, “These are the best bars ever!”

Costco’s description advises keeping them refrigerated, but one reviewer noted they can last at room temperature for about a month. For insights into protein bars’ shelf life, see this guide.

From my experience, many people who transition to gluten-free diets miss pizza the most. While gluten-free pizza varies significantly from regular pizza, some exceptional options truly satisfy. One such option is Kirkland Signature Supreme Cauliflower Crust Pizza, which boasts a 4.8-star rating and nearly 300 reviews on Costco’s website.

One enthusiastic shopper remarked, “This is the best frozen pizza I’ve ever had, and I generally dislike frozen pizza.” Another noted, “This pizza is not just good for being gluten-free; I now prefer its flavor and texture over traditional flour crusts.” 

Costco fans on Reddit and Facebook echo this praise. One Redditor exclaimed, “There’s a generous amount of toppings — both roasted veggies and pepperoni/sausage. I bought six two weeks ago and am already planning to make room in my freezer for more.” A Facebook commenter described them as preferable to similar offerings from chain pizzerias.

While I had heard of MadeGood, I was excited to discover their granola minis. Costco’s variety pack features 12 chocolate chip and 12 mixed berry packs, making them a convenient on-the-go snack. The MadeGood Organic Granola Minis have received a 4.7-star rating and 433 reviews on Costco’s site, alongside over 200 five-star reviews on the company’s website.

One shopper noted, “My husband purchased a bag, and they were delicious and low in sugar! I bought two more bags this week; please continue to stock this amazing snack!” Another reviewer loves the tastiness of the minis: “The chocolate chips offer the perfect sweetness, and the granola is crunchy yet not overly hard. Plus, they are allergen-friendly and made with clean ingredients, making them a guilt-free treat!”

On Instagram, a user praised these as an excellent breakfast addition in yogurt or smoothie bowls. Another Redditor mentioned that they are great snacks for kids.

Of all the gluten-free foods I’ve been eager to explore, ramen has been at the top of my list. The Lotus Foods Organic Millet & Brown Rice Ramen is a standout with a 4.6-star rating and over 500 reviews on Costco’s site, along with nearly 50 4-star ratings on the brand’s website.

One reviewer shared, “I’ve been buying this for years. It’s quick to prepare and versatile in its uses.” Another customer mentioned, “[These] are my favorite ramen noodles; they’re healthier, taste great, and hold their shape.” Reddit users confirm their delight in this ramen, with one stating that it has a nice bite and reminds them of traditional ramen.

Another user offers a cooking tip: “I cook them in chicken broth and fry them with some leftover cooking water, gluten-free soy sauce, and veggies. They turn out crispy and delicious!” If you’re curious about various ramen types, explore our story on 15 different types.

I liken BUILT Puff Protein Bars to marshmallow treats dipped in chocolate. This variety pack includes seven coconut bars and seven brownie batter bars, each offering 17 grams of protein. They are known for tasting remarkably like dessert, backed by a 4.6-star rating on the Costco site and over 3,000 5-star reviews on the brand’s website. Note that not all flavors are gluten-free, so checking the label is essential.

A Costco shopper shared, “This is a fantastic alternative to a candy bar. I picked these up on a whim for my kid to take to camp; we’re looking for healthier snacks.” Another echoed this sentiment, noting their clean ingredients and high protein content.

Many reviews highlight the chewiness of these bars, with one Reddit user raving about the brownie batter flavor. They mentioned the unique texture, describing it as “like a marshmallow left in the sun too long—more like a marshmallow than chewy, but delicious!”

I’m on a mission to enhance my daily protein intake, and the Oats Overnight Protein Shakes provide an efficient solution with 20 grams of protein in each serving. All products from this brand are gluten-free; Costco offers a variety pack featuring Cookies and Cream and Chocolate Peanut Butter Banana flavors, which has a 4.6-star rating and over 320 reviews.

One customer highlighted that Costco’s price is more affordable. They noted, “Both flavors are fantastic! Cookies and Cream is a favorite of mine, while my wife loves the Chocolate Peanut Butter Banana.” Another reviewer praised the Cookies and Cream flavor, comparing it to a milkshake.

Before embracing a gluten-free lifestyle, I used to savor cheese straws. The Sonoma Creamery Pepper Jack Crisps bring back those memories, offering a crunchy and savory snack. With over 1,100 reviews and a 4.5-star rating on Costco’s website, these crisps are delicious whether enjoyed on their own or with a dip.

A satisfied shopper shared a unique suggestion: “They make an awesome crouton replacement on salads or can serve as gluten-free snack crackers.” Another praised the flavor: “Sonoma Creamery produces some of the best cheese snacks, and I’m thrilled Costco stocks them!” These crisps are also excellent for packing or as a tailgate snack, as one user remarked, “They provide a satisfying snack on the go and are quite filling.”

To identify the top gluten-free items, I searched the Costco website for “gluten-free,” yielding 181 results. However, some items listed weren’t actually gluten-free. I then used the dietary feature filter to narrow it down to 106 results. Out of these, 97 products featured ratings of 4.0 stars or higher. I meticulously reviewed each item to ensure they were clearly labeled as gluten-free, not just mentioned that way online; some listings were unclear despite indicating gluten-free in the website description.

After this, I focused on products with over 250 reviews, prioritizing those with several reviews posted in the past year. I chose primarily specialty gluten-free products, as opposed to naturally gluten-free items like potato chips and quinoa. Specialty gluten-free products often use alternative grains to replicate wheat-based foods. My selection included products I would be excited to find as someone with celiac disease, and I also cross-referenced reviews across blogs, social media platforms like Facebook and Instagram, and forums like Reddit.
