Walking down the pantry aisle at Costco can be overwhelming: there are many olive oil options, different label terms, and large container sizes to consider. Before you buy, it helps to understand the varieties so you can choose the best Costco olive oil for your needs in 2024.
Best Costco Olive Oil 2024
Our top pick is the Kirkland Signature Organic Extra Virgin Olive Oil. It delivers a pleasant olive flavor without being overpowering and offers the health benefits associated with extra virgin olive oil.
Costco typically stocks several olive oil options in-store and online. Current varieties include:
- Kirkland Signature Refined Olive Oil and 15% Virgin Olive Oil — $29.99 for 101.44 fl oz
- Filippo Berio Olive Oil — $49.99 for 169 fl oz
- Filippo Berio Extra Light Tasting Olive Oil — $31.49 for 101.44 fl oz

A simple way to compare these products is price per ounce, but price alone doesn’t determine the best choice for your kitchen. Consider flavor, intended use, and how quickly you’ll use the oil, since large containers can sit open for months and olive oil degrades over time.
Costco Olive Oil Review — Is Costco Olive Oil Good?
The Kirkland Signature Organic Extra Virgin Olive Oil stands out for balance and value. As an extra virgin olive oil, it is produced without chemical treatment or heat, which helps preserve natural phenols and flavor compounds. The organic label is an added benefit for shoppers who prefer certified organic products, though many olive groves require minimal pesticide use.
The Kirkland option is reasonably priced relative to quality—about 20 cents per ounce—and it comes in an opaque container that helps protect the oil from light, preserving freshness. The 2-liter size is convenient for many households, and if stored properly it can be used before it degrades.
We use this extra virgin olive oil for roasting, sautéing, baking, marinades, and salad dressings. While the smoke point of extra virgin olive oil is high enough for many cooking applications (see FAQ), deep frying is typically avoided because it requires a large volume of oil and other oils can be more economical.
Costco Olive Oil FAQ
Where does Costco olive oil come from? Is Kirkland olive oil from Italy?
Kirkland Signature Organic Extra Virgin Olive Oil is blended from olives sourced in several countries. Packaging indicates select oils may come from Argentina, Greece, Italy, Portugal, Spain, and Tunisia, and the final product is packaged in the United States.
Can I fry with Kirkland olive oil?
You can fry with olive oil. Smoke point refers to the temperature at which oil begins to smoke; extra virgin olive oil has a smoke point often cited around 410°F, while “light” olive oils have higher smoke points (around 465–470°F). Deep frying typically occurs between 350–375°F, so most olive oils are technically safe for frying. Many home cooks avoid using high-quality extra virgin olive oil for deep frying because of cost.
How long does Costco olive oil last?
Bottles usually display a best-by date 18–24 months from bottling. After opening, olive oil begins to oxidize and is best used within about six months for optimal flavor. Light, heat, and oxygen accelerate degradation, so choose opaque containers, store oil away from direct heat, and seal bottles tightly. If oil smells like crayons or stale nuts, it may be rancid and should be discarded.
Which Costco olive oil is good for cooking?
Extra virgin olive oil is versatile and considered the premium choice for most cooking needs because it retains more flavor and beneficial compounds. Costco’s extra virgin olive oils are priced competitively, making them suitable for roasting, sautéing, baking, and dressings. For deep frying where cost and oil volume matter, a less expensive refined oil is a practical alternative.
What is the healthiest olive oil?
Olive oil in general is a healthy choice due to its high monounsaturated fat content. Extra virgin olive oil has an advantage because it is unrefined, retaining phenolic compounds that act as antioxidants. Some research suggests higher phenol concentrations may provide additional antioxidant benefits, which is one reason extra virgin olive oil is often recommended for health-conscious cooking and finishing dishes.
