If you have olive oil in the kitchen, you can use it to make French fries. But before you heat it, check which oil you have and how you plan to cook the potatoes.
Both extra virgin olive oil and refined olive-oil blends can be suitable for French fries. Choose an oil that its producer recommends for the cooking method and temperature. If you are using an electric fryer, check its permitted oils first. Frozen fries need their own package directions.
The oil’s flavor and cost matter too, especially when you need enough for deep-frying.
What Should You Check Before Frying In Olive Oil?
An oil’s smoke point is the temperature at which it starts to smoke. There is no single smoke point that applies to every bottle of olive oil. UC Davis explains that it varies with the oil’s grade, quality, and freshness, so check the producer’s guidance for the oil you are using.
Use a frying thermometer to monitor the oil rather than guessing from the stove setting. If the oil starts smoking, switch off the heat and let it cool. Do not keep heating it or add potatoes to cool it down.
If you want to reuse frying oil, let it cool completely before handling it. USDA recommends straining used oil and keeping it in a sealed, light-proof container; refrigeration helps preserve its quality.
Do not rely on a fixed number of uses. What you cooked and how you heated the oil affect when it needs replacing. Presto lists an unpleasant smell, smoking during heating, and excessive foaming among the reasons to replace frying oil. Filtering removes food particles, but it does not make deteriorated oil fresh again.
Can You Fry French Fries In Extra Virgin Olive Oil?
Yes, extra virgin olive oil, often called EVOO, can be used for frying when the particular oil and equipment are suitable. For example, California Olive Ranch recommends its extra virgin olive oil for deep-frying. That does not mean every bottle has the same temperature limit.
Extra virgin olive oil is made by mechanical or other physical methods and is not refined. The USDA grade standards also set requirements for its flavor and composition. Its color alone does not tell you whether it is good quality.
Choose an extra virgin oil if you like the flavor it adds and are comfortable using that amount of it. If you would rather save a particular bottle for dressing or dipping, you can choose a milder cooking oil for the fries.
A refined olive-oil blend is another option. For example, Bertolli Cooking Olive Oil contains refined and virgin olive oils, has a mild flavor, and is marketed for deep-frying. Check the current label instead of assuming that all products called olive oil are interchangeable.

How To Fry French Fries With Olive Oil?
Deep-frying cooks the potatoes in a bath of oil. Baking and air-frying use different methods, so their temperatures and cooking times should not be swapped into a deep-frying recipe.
Start with directions for the potatoes and equipment you actually have. The thickness of the fries and the size of each batch matter, so a time given for one recipe will not suit every batch.
How To Deep-Fry French Fries In Olive Oil?
If you are using an electric fryer, read its manual before choosing the oil. Some models advise against olive oil; the Cuisinart CDF-130A manual, for example, excludes it. Follow your model’s permitted oils, minimum and maximum fill marks, and batch limits.
For stovetop frying, use a deep, heavy pan and a frying thermometer. Greater Manchester Fire and Rescue Service says to fill a pan no more than one-third with oil. This leaves room for the potatoes and bubbling; do not keep adding oil just to cover a large batch.
Use a recipe that specifies the potato quantity, cut size, oil temperature, and cooking stages. If it calls for two frying stages, follow its instructions for each stage rather than applying one set of times to every size of potato strip. Alongside that recipe:
- Wash and cut the fresh potatoes to the size the recipe specifies. If you soak or rinse them, drain them and blot them thoroughly dry before they go near the hot oil.
- Heat the oil to the recipe’s temperature only if the oil and equipment are suitable for it. Lower small batches carefully into the oil, and keep watching the temperature while you cook.
- Cook the potatoes through while avoiding dark browning. The FDA recommends a golden-yellow color for cut potato products to reduce acrylamide, a substance that can form during high-temperature cooking.
- Lift the fries out with a fryer basket or a suitable slotted utensil, then drain them on paper towels. Season and serve while hot.
The FDA’s potato-preparation guidance also says that soaking raw slices for 15–30 minutes can reduce acrylamide formation, followed by draining and blotting dry. This is a preparation tip, not a replacement for a complete recipe.
Stay beside the pan while it is heating and cooking. Keep water away from hot oil, and never pour water onto an oil fire. Let the oil cool completely before moving it or cleaning up.
How To Bake French Fries With Olive Oil?
For oven fries, use a measured coating of olive oil rather than filling a pan with it. Choose an oven-fries recipe so that the amount of potato, cut size, oil quantity, and oven setting work together.
For example, James Madison University’s oven-fries recipe uses four small to medium potatoes and two tablespoons of olive oil. It describes thick matchstick cuts and an oven setting of 450°F, with an estimated cooking time of 25–30 minutes. Those details belong to that recipe; they are not a universal schedule for fresh or frozen fries.
When you follow an oven recipe, prepare and dry the potatoes as directed, coat them with the measured oil, and spread them over the baking sheet without piling them up. Follow its turning instructions and check that the centers are cooked. Avoid dark browning rather than keeping the fries in the oven just to reach a stated time.
If you use an air fryer instead, follow a recipe for that appliance or the directions on the fries package. Do not fill an air fryer with deep-frying oil.

Can You Fry Frozen French Fries In Olive Oil?
You can use a suitable olive oil if the frozen fries’ package allows deep-frying and your fryer permits that oil. Follow the package’s cooking method, temperature, batch size, and time rather than using the fresh-potato instructions above.
Keep fries frozen when the package tells you to cook them from frozen. Before deep-frying, remove loose surface ice and lower small batches carefully to limit splashing and boil-over. Do not rinse frozen fries before putting them in hot oil.
For oven or air-fryer products, follow those package directions instead. Check whether extra oil is needed before adding any. Cook the fries through and aim for a golden-yellow finish rather than a dark-brown one.
