Understanding Gluten Risks in Store-Bought Pesto
Traditional pesto is made from basil, pine nuts, garlic, olive oil, and hard cheese, all of which are naturally gluten-free. However, when it comes to mass-produced, store-bought pesto, several factors can introduce gluten, making label scrutiny essential.
- Cross-Contamination: The most significant risk comes from shared equipment in production facilities. If the same machines are used to process gluten-containing products like pasta and then pesto, traces of gluten may be transferred. This is a major concern for individuals with celiac disease.
- Thickeners and Additives: Some manufacturers add thickeners to improve texture or stability. While many are gluten-free (like tapioca or potato starch), some may use unspecified 'flour' which could contain wheat. Always avoid products listing generic 'flour' on the ingredient list.
- Labeling Changes: Product formulations and labeling can change over time. As highlighted on Reddit's Celiac forum, a brand like Classico was once considered gluten-free but reportedly removed its official gluten-free label at some point, causing confusion. This emphasizes the importance of checking the most recent packaging.
Brands with Dependable Gluten-Free Pesto
Thankfully, several brands reliably offer gluten-free pesto options. These brands are either certified gluten-free or explicitly state their products are safe for a gluten-free diet.
- Barilla: Barilla is a widely available brand that offers multiple gluten-free pesto varieties, including their Pesto alla Genovese, Rustic Basil Pesto, and Pesto Rosso. Their product pages and packaging explicitly state they are gluten-free.
- Sacla': A UK-based brand known for its Italian sauces, Sacla' dedicates a portion of its product line to gluten-free options. Shoppers can specifically find their gluten-free products on their website, which include vegan choices as well.
- Gotham Greens: Known for its refrigerated fresh products, Gotham Greens offers a high-quality basil pesto that uses pure, naturally gluten-free ingredients and is a popular choice for freshness.
- Magrini Le Delizie: An Italian manufacturer specializing in sauces, Magrini Le Delizie explicitly states that all of its products are gluten-free and refrigerated.
Brands to Approach with Caution
- Kirkland Signature (Costco): The gluten-free status of Kirkland pesto is inconsistent. While some versions have been identified as gluten-free in the past, a post on Reddit noted potential cross-contamination warnings. The official Ubuy Qatar product page for Kirkland Signature Italian Basil Pesto also explicitly states it is not gluten-free. It is crucial to read the specific label on the jar you are purchasing.
- Trader Joe's: Trader Joe's product availability and ingredients can vary by location and season. While some versions of their pesto may be naturally gluten-free, they do not consistently carry a third-party certification. Always check the ingredients and allergen statements carefully.
- Classico: As previously mentioned, Classico's labeling has changed, with reports that the gluten-free label was removed from some products. This is a brand where reading the label is absolutely non-negotiable for anyone with gluten sensitivities.

What to Look for on the Label
For those with celiac disease or significant gluten sensitivity, relying on certifications is the safest approach. The Gluten-Free Certification Organization (GFCO) and the European Crossed Grain symbol are two highly reliable marks. Here’s what to look for:
- GF Certified Label: Look for a trusted third-party certification mark on the packaging. These indicate that the product has been tested to meet strict gluten-free standards, often below 10 or 20 ppm of gluten.
- Allergen Statement: Check the 'Contains' and 'Manufactured in a facility that also processes' statements. If it mentions wheat or gluten, it should be avoided due to cross-contamination risk.
- Ingredient List: Read the full list to ensure no hidden gluten sources are present. Look out for non-specific terms like 'natural flavors' or 'modified food starch', which could contain gluten.
The Safest Choice: Homemade Gluten-Free Pesto
For absolute certainty, making your own pesto from scratch is the best option. It allows you to control every ingredient and avoid any risk of cross-contamination. Many recipes are readily available online. You can also experiment with different nuts or seeds, like walnuts or pumpkin seeds, for a unique flavor profile or to avoid tree nuts.
Conclusion
While traditional pesto contains no gluten, the manufacturing process for store-bought versions can introduce cross-contamination. Brands like Barilla and Sacla' offer clearly labeled, gluten-free options that are generally safe. Always read the ingredient list and allergen warnings on brands like Kirkland and Trader Joe's, as their gluten-free status may be inconsistent or uncertified. The most secure choice for those with celiac disease or severe gluten intolerance is to make homemade pesto using certified gluten-free ingredients. Your health and peace of mind are worth the extra caution. For more information on certified gluten-free products, visit the Gluten-Free Certification Organization at https://gfco.org/.
