Choosing organic grocery items can be one way to limit your exposure to certain synthetic pesticides and other substances used in conventional farming while also supporting organic agricultural practices. For shoppers who prioritize organic foods, Costco's impressive selection of USDA-certified organic groceries makes stocking up on them not only more convenient but also easier on your budget.

At Costco, you can find brand-name organic favorites offered in bulk from a variety of the warehouse's grocery departments, including produce, dairy, eggs, meat, and frozen. However, the majority of the warehouse's highest-rated organic goods are pantry staples and snacks; many of these products come from its private-label Kirkland Signature brand.

On this list, you'll find 12 best of Costco's best organic products, each of which earned higher than a 4.5-star rating across more than 1,000 ratings. These shopper favorites cover a little bit of everything, from organic coffe and  baking and cooking staples that'll last through dozens of recipes to organic snacks for munching, adding to meals, or helping reach your protein goals.

While organic peanut butter may cost the least of all the nut butter varieties, finding one that costs only $0.18 per 1-ounce (2 tablespoons) serving (or roughly $5 per 28-ounce jar) is hard to beat. But that's exactly what you get with Kirkland Signature Organic Creamy Peanut Butter. The peanut butter, which comes in a two-pack, is made from just two ingredients: dry roasted organic peanuts and salt. Its simplicity and creamy texture offer versatility for snacks, meals, or baked goods. Customer reviews also frequently say this is the best-tasting peanut butter they've ever had, helping earn it a 4.6-star rating from more than 4,000 ratings.

In a ranked list of the best and worst Costco olive oils, our reviewer wrote, "The bestselling Kirkland Signature Organic Extra Virgin Olive Oil is, by all accounts, the most beloved olive oil on Costco's website." The olives are cold extracted, meaning their oil is extracted without high-heat processing, which helps maintain the extra virgin olive oil's natural mild, fruity flavors and antioxidant qualities. It's also just shy of $21 for a 2-liter bottle, which is about half the price of comparable name-brand options — no wonder it's one of Costco highest-rated products overall, at 4.8 stars from nearly 6,500 ratings.

You can buy Kirkland Signature Organic Extra Virgin Olive Oil for $20.99.

Kirkland Signature Organic Maple Syrup is another one of Costco's highest-rated products, with a 4.9-star rating from almost 6,000 ratings. Customer reviews frequently mention how flavorful the maple syrup is, while also appreciating that it's organic and sold at a competitive price. You get one liter of organic 100% pure maple syrup for a price that's just a few dollars' more than what some grocery stores charge for a 12-ounce bottle. And its U.S. Grade A amber color gives it a rich, classic taste that's versatile enough to add natural sweetness to just about anything, from pancakes and coffee to dressings and marinades.

Kirkland Signature Organic Maple Syrup is available for $14.99.

For shoppers who want a granulated sugar that undergoes less chemical processing and is from sugar cane grown without synthetic pesticides or fertilizers, organic cane sugar is a good option. It has the same sweetness and texture as its conventional counterparts, which makes it an easy swap for everyday sweetening, baking, and cooking without requiring any adjustments. Costco's Kirkland Signature Organic Cane Sugar offers shoppers the purity and value they're looking for; the 10-pound bag has earned 4.8 stars from over 3,500 ratings.

One of Costco's most popular organic granolas, with nearly 3,000 ratings and 4.8 stars, Kirkland Signature Ancient Grains Granola comes in a 35.5-ounce bag and contains probiotic cultures. The price of this bag is comparable to what you'd pay at a traditional grocery store for a 24.7-ounce granola from Nature's Path. 

Customer reviews note that they love how flavorful the granola is without mix-ins or a ton of added sugar. As such, the Ancient Grains Granola is a fiber-packed go-to option for meal-prepping yogurt parfaits, enjoying with milk, or snacking on straight from the bag.
