Vegan Finds at Costco

Costco isn't a vegan store, but it's a very good one for vegans. Buying tofu, plant milk, frozen vegetables, nuts and maple syrup in bulk is exactly what a warehouse club is for. And Costco's own brand, Kirkland Signature, has quietly built up a solid list of products with no animal ingredients.

This list includes only products we found confirmed in recent sources (2025 and 2026). We checked it in October 2026. Costco's range changes constantly and differs between warehouses and regions, so treat it as a shopping list to look for, not a promise of what's on the shelf.

How to read this list

• Vegan: no animal ingredients on the current label.
• Likely vegan: listed as vegan by a reliable source, with one thing worth checking.
• Check the label: the recipe varies or changes often.
• Grey area: contains cane sugar that may be filtered with bone char. Most vegans don't avoid it; see our sugar guide.

"May contain" warnings are allergy notes, not animal ingredients, and don't change a status.

Plant protein

The tofu is the big news. It's extra-firm, which makes it the most useful all-rounder for stir-fries, scrambles and crispy baked tofu. Four blocks is a lot, but unopened tofu keeps well in the fridge until its date. If you're new to it, start with Tofu 101.

Dairy alternatives

Costco's plant milk aisle also rotates name brands, such as coffee-shop style oat and almond milks. Read the label for vitamin D3, which is the only common catch in plant milk.

Frozen

Snacks

Bakery

The in-store bakery is the hardest section for vegans. If you find a bread you like, read the ingredient label on each pack, not just the first time.

How to shop vegan at Costco

1. Check the Costco app before you drive. Search for an item and filter by your warehouse. Many plant-based products are regional.
2. Read every label, every time. Kirkland products are made by different suppliers, and recipes change. Look for milk, whey, casein, egg, honey, gelatin and vitamin D3.
3. Look at the allergen line first. In the US, milk and egg must be declared. If they're in the "contains" line, you're done.
4. Don't panic about "may contain". It's an allergy warning, not an ingredient.
5. Buy what you'll use. A four-pack of tofu or a bulk bag of berries is great value, but only if it fits in your fridge or freezer.

Costco in the UK and Ireland

Costco runs around 30 warehouses in the UK, and its range is different from the US, including many of the Kirkland products. As far as we could find in October 2026, there is no Costco warehouse in the Republic of Ireland, so the nearest for most Irish shoppers is the Belfast warehouse in Northern Ireland.

If you do shop at a UK Costco, the same rules apply. UK labels show allergens such as milk and egg in bold in the ingredients list, and many products carry a vegan logo. Don't assume a Kirkland product with the same name has the same recipe as the US version.

The bottom line

For vegans, Costco is at its best for staples: Kirkland tofu and almond milk, frozen fruit and vegetables, nuts, peanut butter, maple syrup and hummus. Add a bulk pack of Beyond Burgers if your warehouse has them, read the label on anything from the bakery, and check the app before you go. For more unusual vegan products in smaller packs, Trader Joe's is the better bet.
