Oils & FatsYear-round. Most cooking oils are produced from shelf-stable seed and nut crops harvested seasonally but processed and stored for year-round distribution. Harvest timing varies by source—olive oil harvests typically occur in autumn and winter in the Northern Hemisphere, while other seed oils have different seasonal rhythms depending on growing regions.

Cooking oils are calorie-dense (approximately 120 calories per tablespoon) and composed entirely of fat, with nutritional profiles varying by source—olive oil and canola oil are rich in monounsaturated fats and contain polyphenols and other beneficial compounds, while oils vary in their ratios of saturated to unsaturated fats.

About

Cooking oil refers to liquid fats derived from plant, animal, or synthetic sources that remain liquid at room temperature and are suitable for culinary applications. These oils are extracted from seeds, nuts, fruits, or animal tissues through mechanical pressing, chemical extraction, or rendering. Common sources include olives, sunflowers, coconuts, peanuts, canola, corn, soybeans, and sesame plants, as well as animal fats such as lard and tallow. Cooking oils vary significantly in flavor profile, smoke point (the temperature at which the oil begins to degrade and produce smoke), and nutritional composition depending on their origin and processing method. The smoke point is crucial for determining appropriate cooking methods—refined oils typically have higher smoke points suitable for high-heat cooking, while unrefined oils with lower smoke points are better for dressings and low-heat applications.

Different oils possess distinct characteristics: extra virgin olive oil has a fruity, robust flavor and low smoke point; neutral-tasting oils like canola and sunflower offer versatility; coconut oil provides richness and a slight coconut note; sesame oil delivers intense nutty flavors; and nut oils such as walnut or almond oil contribute distinctive tastes suitable for finishing dishes.

Culinary Uses

Cooking oils serve as fundamental culinary mediums across all culinary traditions, functioning for sautéing, frying, roasting, baking, and dressing. Different oils are selected based on desired heat tolerance and flavor contribution: refined oils with high smoke points (such as canola, safflower, or refined vegetable oil) are employed for deep-frying, stir-frying, and high-heat cooking; medium smoke point oils like olive oil suit sautéing and pan-frying; while delicate unrefined oils and nut oils are reserved for finishing, drizzling, and vinaigrettes. Regional cuisines show strong oil preferences—Mediterranean cooking emphasizes olive oil, Asian cuisines favor peanut and sesame oils, Indian cooking utilizes mustard and coconut oils, and many Western applications employ neutral vegetable oils. Oils also serve as vehicles for fat-soluble flavor compounds and contribute textural richness to emulsions, baked goods, and sauces.

Forms & Preparations

Extra virgin/cold-pressed — Unrefined oil extracted without heat, retaining robust flavor and lower smoke point; used for finishing, dressings, and dipping.
Refined/neutral — Processed to remove impurities and flavors, resulting in higher smoke point and neutral taste; ideal for all-purpose cooking and high-heat applications.
Infused — Oil combined with herbs, spices, or other flavorings for culinary applications; used for finishing dishes or as condiments.
Blended vegetable oil — Mixture of multiple seed or vegetable oils optimized for cooking performance and neutral flavor; common all-purpose cooking oil.
Spray or aerosol — Oil dispensed in fine mist form for even, minimal-fat coating of cookware or food; convenient for portion control.
Specialty/nut oils — Oils from walnuts, almonds, hazelnut, or other sources; typically unrefined with distinctive flavors, used for finishing and flavor enhancement rather than cooking.
