Cooking Fat Smoke Points — The Complete Guide to Which Fat to Use and When

The smoke point of a cooking fat is the temperature at which it begins to break down and produce visible smoke. At and above this temperature, the fat starts to oxidise, producing compounds called aldehydes and acrolein that give food a bitter flavour and, at higher temperatures, may be harmful when inhaled or consumed. Choosing the right fat for the right cooking method is one of the most practical things you can know about seed oil free cooking.

The guide below covers every fat used across the recipes on this site, with smoke points, ideal cooking methods, and what to buy.

Ancestral Fat Smoke Points — At a Glance

A note on smoke point and stability: a high smoke point does not always mean a fat is more stable. Refined seed oils have artificially elevated smoke points due to the deodorisation process — but they are chemically unstable and produce harmful oxidation products even below their smoke points. The ancestral fats above are both stable and have high smoke points.

Which Fat to Use and When

Deep frying (375-400°F / 190-204°C)

Beef tallow is the gold standard for deep frying. It was what McDonald's used until 1990 — the reason the fries tasted better. It produces a crisper exterior than seed oils, imparts a mild flavour that enhances rather than competes with the food, and can be strained and reused 3-4 times. Ghee is the alternative for a slightly more neutral result. Refined avocado oil is the most neutral option if you want no flavour addition at all.

Searing and smash burgers (400°F+ / 204°C+)

Beef tallow reaches the temperatures needed for a proper sear on a smash burger or a steak. Add tallow to the pan before the meat, let it reach shimmering point, then add the protein. The fat's high smoke point means you can get the pan genuinely hot without producing harmful compounds.

Roasting (350-425°F / 177-218°C)

Beef tallow for potatoes, root vegetables, and meat. The fat coats the surface of the food and creates the Maillard reaction — the browning that produces roasted flavour. Tallow roast potatoes are categorically different from potatoes roasted in olive oil. Lard is an excellent alternative.

Indian and South Asian cooking (350-400°F / 177-204°C)

Ghee is the traditional fat for Indian cooking and has been for thousands of years. Its high smoke point handles the tempering of whole spices without burning. It adds a background richness that butter cannot achieve at high heat. All the Indian recipes on this site use ghee.

Baking (325-375°F / 163-190°C)

Butter and lard. For anything sweet, butter is usually the right choice — its flavour is an asset in cookies, cakes, and shortbread. For pastry and pie crust, lard produces a flakier, more tender result than butter because its fat crystals are larger and it contains almost no water. The combination of lard for the pastry and butter for the filling is the traditional method.

Dressings and no-cook applications

Extra virgin olive oil. Never heat EVOO above medium — its polyphenols and flavour compounds begin to degrade above 375°F, and the oil is too expensive and flavourful to waste on high-heat applications. Use it cold or warm.

Low-heat sauces and finishing (below 302°F / 150°C)

Whole unsalted butter. At these temperatures, butter adds richness and flavour without burning. Add it at the end of a pan sauce off the heat, swirling to emulsify. This is the technique behind French restaurant sauces — called monter au beurre.
