WHAT IS IT?
Deep-frying is a method of cooking that uses hot oil. It’s a form of dry cooking because water isn’t involved. Food is submerged in a pot of oil or fat, where it cooks quickly thanks to the oil’s intense heat transfer and its high concentration. The result is a crisp exterior that seals in moisture, producing textures many Canadians and Americans crave in quick meals and snacks.
Historical records show oil-based cooking goes back to ancient times, with the ancient Egyptians among the early practitioners who used fat to prepare meat and vegetables. Frying emerged as a practical way to prepare meals rapidly, a trait that has kept it popular through centuries and across cultures. The core idea remains the same: high heat, a fat medium, and a brief cooking time that delivers speed and crunch.
Almost anything can be deep-fried with the right preparation. Some foods can be dunked straight into hot oil, while others benefit from coatings to hold shape and texture. Restaurants around the world feature fried fare beyond the classic chicken and fries. Menu staples have included treats like battered sweets and oddball items such as candied doughs. In North American menus, you’ll still find a spectrum from simple fried vegetables to inventive confections—each relying on careful battering, breading, or batter styles to achieve the intended crust and moisture balance.
Is it bad for you? Fat plays a role in providing energy and supporting bodily functions, and small amounts can contribute to healthy-looking skin and hair. Yet too much fat, especially saturated fat, is linked to health concerns such as heart disease when consumed in excess. The health impact of fried foods depends on several factors, including the type of oil used, the cooking method, and how often frying occurs. Moderation and context matter for most diets in North America, where fried items can be enjoyed as occasional indulgences rather than daily staples.
Can frying be healthy? It depends on the oil and the technique. Oils rich in monounsaturated fats, such as olive oil varieties, and blends designed for high-heat frying can support a balanced fat intake when used properly. Softer fats like butter are flavorful but have lower smoke points for deep-frying at high temperatures, so they aren’t the best choice for most deep-fry applications; clarified butter or ghee can be used with caution. Margarine’s health profile varies by brand and formulation, and modern options often emphasize unsaturated fats rather than saturated fats. The key is selecting oils with high smoke points and favorable fatty-acid profiles, maintaining steady temperatures, and avoiding excessive reuse of oil. There are also lower-oil alternatives, including air-frying or oven-frying, that deliver similar textures with less added fat.
