Why Canola Oil Is Replacing Olive Oil for Everyday Cooking

The bottle of olive oil on the kitchen worktop once seemed beyond question.

It was a kind of golden badge that said, “I’m cooking healthily.” Then its price began creeping up. One day, you are pouring it freely into a frying pan; the next, you are measuring it in spoonfuls and inspecting the label as though it were an expensive fragrance. Meanwhile, the headlines keep shifting the goalposts: healthy fat, unhealthy fat, extra virgin, adulterated blends, rising prices.

Amid this confusion, a low-key alternative has occupied supermarket shelves for years. It is inexpensive, dependable and almost unremarkable. Yet an increasing number of nutrition scientists are making the same quiet point: this supposedly ordinary oil may be the sensible option for everyday cooking.

Farewell to olive oil on weeknights. Welcome canola oil.

Why shoppers are gradually turning away from olive oil

The initial surprise is seldom about health; it is usually the total at the till. In the cooking-oil aisle, shoppers do the quick calculation between a large plastic bottle of canola oil and a narrow glass bottle of extra-virgin olive oil costing almost twice as much for half the amount. People pause, pick up the olive oil, return it to the shelf, then choose the cheaper bottle with a faintly guilty expression.

For years, olive oil has carried an aura of “Mediterranean magic”. Giving it up can feel like abandoning an aspirational life in which tomatoes are always sweet and supper is served on a sunny terrace. But the reality is less idyllic: household budgets are stretched, and that supposedly healthy splash of oil is becoming a financial burden.

On a wet Tuesday, with a trolley filled with essentials, healthy eating suddenly needs to be affordable too.

One figure is particularly striking: in some countries, olive oil prices have risen by more than 30–40% in only a few years. One reader told me she had begun hiding her best olive oil from her teenagers, reserving it “for special occasions” in the way others hide chocolate. Another man admitted that he had stopped purchasing it completely and returned to the large canola oil bottle he remembered from his student days.

Supermarket data reflects the same pattern. Lower-cost oils, especially canola oil, are becoming more popular for daily cooking, while olive oil is moving towards being a “weekend treat”. Those shoppers still want protection against heart disease, inflammation and weight gain, however. The unspoken question is therefore: am I sacrificing health to save money?

This is where the story becomes unexpectedly different.

Once the marketing appeal is set aside and only nutrition and cooking science are considered, canola oil begins to look like the practical everyday choice. Like olive oil, it is naturally low in saturated fat and high in monounsaturated fats. It also provides omega-3 fatty acids, something many of us are seriously lacking.

For cooking at high temperatures, canola oil can often be the safer choice: its mild flavour and reliable smoke point make it steadier in the pan than many extra-virgin olive oils, which deteriorate more quickly when overheated. This means less burnt taste and fewer potentially harmful compounds. Its lower cost also makes people more likely to use an appropriate amount rather than constantly rationing it.

Health is not only about finding the “perfect” ingredient. It is about choosing what works in daily life without unnecessary stress.

Moving from olive oil to canola oil without feeling you are “downgrading”

The simplest way to start using canola oil is to give it a defined purpose: make it your standard choice for cooking, frying and baking. If you keep olive oil, save it for finishing dishes and adding flavour. Begin gradually. Choose one week in which, whenever you would normally add olive oil to a hot pan, you use canola oil instead. Stir-fries, omelettes, roasted vegetables, pancakes and cheese toasties all work very well with canola oil.

If flavour is your concern, try a straightforward comparison. Roast two trays of potatoes, one with olive oil and the other with canola oil. Season both in the same way. Once herbs and spices are added, most people can hardly detect a difference. That is the real advantage of a neutral oil: it stays in the background and allows the food itself to stand out.

There is no need to transform your entire kitchen. Make one intentional substitution at a time.

Many people carry a quiet sense of shame about cooking. There is an idea that “proper” healthy cooking requires buying the costliest form of every ingredient: organic, cold-pressed, extra-virgin, picked at dawn by monks. Real life does not look like that. Some days you are exhausted, the children are noisy, your banking app is alarming, and you simply want to put a reasonable meal on the table without overthinking it.

This is precisely where canola oil proves useful. It is the dependable workhorse. You can add it to the pan without recoiling at the cost. You can use it for cakes, speedy marinades and a vinaigrette that does not overpower a salad. And no, choosing not to spend half your budget on an elegant glass bottle does not mean you are “ruining” your health goals.

Let’s be honest: nobody follows ideal nutritional advice every day. The key is making the easier option a sensible one as well.

Many nutrition experts now regard canola oil as a practical ally. It may not be fashionable, but it is consistently reliable.

“If choosing canola oil instead of olive oil means you actually cook more at home instead of ordering fast food, the health win is obvious,” says a preventive cardiologist I spoke with. “I’d rather see people sauté vegetables in canola oil than skip them because everything feels too expensive.”

Consider the less obvious ways in which having an affordable, healthy basic oil may alter your habits:

• You no longer “save” your oil, so you cook vegetables more regularly.
• You have greater control over the fat in your meals instead of depending on ultra-processed food.
• You feel less stressed at the checkout, which, oddly, can make it easier to follow your shopping list.
• You can experiment with herbs and spices because canola oil’s neutral character will not compete with them.

A stylish bottle of oil for drizzling can still have a role. For everyday use, though, the oil that quietly supports your routine is the one that succeeds over time.

A simple checklist for deciding whether canola oil is right for you

Selecting canola oil instead of olive oil is not a moral choice. It is a choice of tool, like wearing trainers rather than leather shoes because you are genuinely going to walk. Start with three direct questions: Do I mostly cook at medium to high temperatures? Do I value the cost per meal more than the “romance” of the label? Do I want a single oil that can be used in nearly everything?

If you answer yes most of the time, canola oil is likely to be the better default for you. For frying, sautéing, batch cooking, Sunday pancakes and weekday stir-fries, it discreetly meets most needs: heart-friendly fats, a reasonable omega-3 content, a low cost and a neutral flavour. Olive oil can remain an accent for salads, dips and special dishes if that gives you pleasure.

The oil that enables you to cook more often, rather than less, is generally the healthiest choice in the end.
