Crisco Smoke Point: Shortening, Frying & Cast Iron Guide

The smoke point of Crisco All-Vegetable Shortening is commonly listed around 360°F, or about 182°C. Treat that as a practical estimate, not a hard line. Smoke points vary with product formula, age, pan type, food particles, repeated heating, and how accurately your thermometer reads.

The key takeaway is simple: solid Crisco shortening is useful for baking, pan frying, deep frying at controlled temperatures, greasing pans, and cast iron seasoning, but it is not the same as a high-smoke-point liquid frying oil. If your shortening is smoking heavily, it is too hot. Reduce the heat and do not leave it unattended.

Crisco’s own frying guidance uses temperatures around 350°F to 375°F for specific recipes, which is right in the normal frying range. That means you can fry with Crisco, but you should use a thermometer and manage heat carefully instead of guessing by eye.

Quick answer: what is the smoke point of Crisco?

Do not confuse Crisco solid shortening with Crisco vegetable oil, canola oil, olive oil, or cooking spray. They are different products with different formulas and heat behavior. This article focuses mainly on Crisco All-Vegetable Shortening, the solid white shortening sold in cans and baking sticks.

What is Crisco shortening?

Crisco All-Vegetable Shortening is a solid vegetable shortening used for baking and cooking. Current Crisco product information lists soybean oil, fully hydrogenated palm oil, palm oil, mono and diglycerides, TBHQ, and citric acid as ingredients for its all-vegetable shortening.

In baking, shortening helps create tender textures because it coats flour and limits gluten development. That is why it is often used in pie crusts, biscuits, cookies, and frostings. Unlike butter, shortening has little water and no milk solids, so it behaves differently in recipes. It also has a more neutral flavor than butter.

Crisco’s product page describes the all-vegetable shortening as useful for baking and frying, but it also warns that shortening can catch fire if overheated. That warning matters more than chasing an exact smoke-point number.

What does smoke point mean?

A smoke point is the temperature where a fat begins producing visible smoke. When fat is heated beyond that point, it starts breaking down more quickly. The result can be acrid smoke, bitter flavor, faster rancidity, and lower quality food.

Smoke point is not the same as flash point. Smoke means the fat is breaking down. Flash point is the more dangerous stage where vapors can ignite. You should not intentionally hold shortening at a smoking temperature while cooking.

If Crisco begins smoking in a pan, lower the heat or move the pan off the burner. If a grease fire starts, turn off the heat if you can do so safely, cover the pot with a lid, and do not add water.

Crisco smoke point vs other oils and fats

Smoke-point charts are best used as guides, not guarantees. Refining, age, storage, food crumbs, and repeated heating can all change how a fat behaves. Still, this table gives useful practical comparisons.

Fat or oil	Approximate smoke point	Best practical use
Crisco All-Vegetable Shortening / vegetable shortening	About 360°F	Baking, pan frying, controlled deep frying, cast iron seasoning.
Butter	About 300°F to 350°F, depending on source and milk solids	Low to medium heat, baking, finishing, sauces.
Clarified butter or ghee	About 450°F	Higher-heat cooking when butter flavor is wanted.
Canola oil	About 400°F	General frying, sautéing, baking, neutral cooking.
Vegetable oil	About 400°F to 450°F	Deep frying, pan frying, baking, neutral cooking.
Peanut oil	About 450°F	Deep frying, wok cooking, high-heat frying.
Refined avocado oil	Often listed around 480°F to 520°F	High-heat searing and frying.
Extra-virgin olive oil	Often listed around 325°F to 410°F	Sautéing, roasting, dressings, finishing; exact use depends on oil quality.

For Crisco specifically, the important comparison is between solid shortening and liquid oils. Solid shortening can fry food, but if you want more heat margin for deep frying, a refined liquid oil such as peanut, canola, vegetable, or refined avocado oil may be easier to manage.

Is Crisco good for deep frying?

Yes, Crisco shortening can be used for deep frying when the temperature is controlled. It melts into a liquid fat, has a neutral flavor, and can give fried foods a crisp texture. It also solidifies again as it cools, which can be convenient or inconvenient depending on how you clean up and store used fat.

Most deep frying works in the 325°F to 375°F range. Since vegetable shortening is commonly listed around 360°F, you have less margin than you would with a high-smoke-point oil. That does not mean Crisco cannot fry food. It means you should use a thermometer and avoid overheating.

• For fried chicken: aim for controlled heat around the recipe’s target, often near 350°F.
• For hush puppies and fritters: 350°F to 360°F is a common working range.
• For small appetizers: 350°F to 375°F can work, but watch carefully for smoke.
• For high-heat searing or stir-frying: choose a higher-smoke-point oil instead of solid shortening.

If you are deep frying poultry, the oil temperature is only part of the job. The food still needs to reach a safe internal temperature. For chicken, check the thickest part with a reliable thermometer. See our guide to the best instant-read thermometers for tool help.

Crisco frying safety tips

Hot shortening can burn, splatter, smoke, and catch fire if overheated. Treat it like any other deep-frying fat.

1. Use a deep, heavy pot or skillet with room above the fat line.
2. Do not fill the pot more than halfway with melted shortening.
3. Use a frying or candy thermometer instead of guessing.
4. Dry wet foods before adding them to hot fat.
5. Lower food in gently to prevent splashing.
6. Do not leave hot shortening unattended.
7. Reduce heat if the shortening begins smoking.
8. Never pour water on hot or flaming shortening.
9. Let used shortening cool before straining, storing, or discarding.

Discard used Crisco if it smells rancid, smokes before it reaches frying temperature, foams excessively, turns very dark, becomes sticky, or contains burnt food particles. Reusing fat is never worth ruining the next batch of food or creating a smoky kitchen.

Can you substitute Crisco for vegetable oil?

Sometimes. Once melted, Crisco shortening can replace vegetable oil in some frying and sautéing situations. But it is not a perfect one-for-one swap in every recipe because shortening is solid at room temperature and has a different fat structure than liquid oil.

Use case	Can Crisco replace oil?	Best advice
Deep frying	Yes, with temperature control	Melt first, use a thermometer, and avoid heavy smoke.
Pan frying	Yes	Good for moderate-heat frying where neutral flavor is wanted.
Stir-frying	Usually not ideal	Use peanut, vegetable, canola, or another high-smoke-point liquid oil.
Cakes that call for oil	Not usually	Use the oil called for unless the recipe provides a shortening variation.
Pie crust and biscuits	Yes, often	Use a shortening-specific recipe for the best texture.
Greasing pans	Yes	Shortening works well because it coats surfaces evenly.
Salad dressings	No	Use liquid oil.

If a recipe depends on the flavor and water content of butter, Crisco will change the result. If a recipe depends on liquid oil for moisture, melted shortening may make the texture heavier or firmer after cooling.

Is Crisco good for baking?

Crisco shortening is often useful in baking because it is neutral, solid at room temperature, and easy to cut into flour. It can make pie crusts tender, cookies softer, and frostings more stable. It does not taste like butter unless you use a butter-flavor product, and even then it is not identical to butter.

Use Crisco in recipes designed for shortening. For pie crusts and biscuits, keep the shortening cold and avoid overworking the dough. For cookies, shortening can reduce spread and create a softer texture than butter. For frosting, shortening can improve stability but will not add dairy flavor.

Can you season cast iron with Crisco?

Yes. Crisco shortening is a common cast iron seasoning fat because it is inexpensive, neutral, easy to wipe on, and easy to find. The important part is not the brand name. The important part is applying an extremely thin layer and heating the pan long enough for the fat to polymerize into a hard seasoning layer.

Because Crisco’s smoke point is commonly listed around 360°F, seasoning at higher oven temperatures can create smoke. That is normal for many cast iron seasoning methods, but you should ventilate your kitchen, wipe off nearly all visible fat before baking, and avoid leaving thick, sticky oil patches on the pan.

1. Start with a clean, dry cast iron pan.
2. Warm the pan slightly so the shortening spreads easily.
3. Rub on a tiny amount of Crisco.
4. Wipe the pan again until it looks almost dry.
5. Bake upside down according to your cast iron seasoning method.
6. Let the pan cool safely before handling.

For a full cast iron process, link this page to your dedicated guide: how to season cast iron. If you are comparing oils for seasoning, see seasoning cast iron with flaxseed oil and best oil for seasoning carbon steel.

What to do if Crisco starts smoking

Light wisps of smoke can happen when a pan is hot, especially during cast iron seasoning. Heavy smoke while cooking means the fat is too hot or there are burnt food particles in the pan.

• For frying: lower the heat or move the pot off the burner until the temperature drops.
• For pan frying: remove burnt crumbs and add fresh shortening if needed.
• For cast iron seasoning: make sure the coating was wiped extremely thin and ventilate the kitchen.
• For a grease fire: turn off the heat if safe, cover the pot, and do not use water.

Do not pour smoking shortening back into the Crisco can. Let it cool in a safe container first. Hot fat can melt packaging, cause burns, and create a fire hazard.

How to store Crisco after opening

Store Crisco shortening tightly closed in a cool, dry place away from heat, light, air, and water. Do not store the can over the stove or beside the oven. Heat and oxygen speed up rancidity, which can make shortening smell stale or taste unpleasant.

• Use a clean spoon or spatula every time.
• Keep crumbs, water, and food particles out of the can.
• Close the lid tightly after each use.
• Discard shortening that smells rancid, sour, paint-like, or stale.
• Do not refill the can with hot used shortening.

If you are storing several fats and oils, use the same basic rule for all of them: cool, dark, sealed, and clean.

Crisco smoke point FAQ

What is the smoke point of Crisco vegetable shortening?

Crisco All-Vegetable Shortening is commonly treated as having a smoke point around 360°F. Because smoke points vary, use that as a practical estimate and watch the fat itself. If it smokes heavily, reduce the heat.

Can you deep fry with Crisco shortening?

Yes. You can deep fry with Crisco shortening at controlled temperatures. Use a thermometer, avoid overheating, and keep the shortening in the normal frying range for the food you are cooking.

Is Crisco a high-smoke-point oil?

No. Solid Crisco shortening is better described as a medium-smoke-point fat. Liquid oils such as peanut oil, canola oil, vegetable oil, and refined avocado oil usually give more heat margin for high-temperature frying or searing.

Is Crisco shortening the same as Crisco vegetable oil?

No. Crisco shortening is a solid fat, while Crisco vegetable oil is a liquid oil. They are different products and should not be assumed to have the same smoke point or cooking behavior.

At what temperature should I fry with Crisco?

Most foods fry well between 325°F and 375°F. For Crisco shortening, start around 350°F when you are unsure, then adjust based on the recipe and the food. Use a thermometer because melted shortening can get too hot quickly.

What happens if Crisco smokes?

Smoking means the shortening is breaking down and the pan is too hot. Lower the heat, move the pan off the burner, and let the temperature come down. If the shortening smells burnt or contains scorched crumbs, discard it after it cools.

Can Crisco catch fire?

Yes. Like other cooking fats, shortening can catch fire if overheated. Never leave hot shortening unattended, reduce heat if smoking occurs, and never put water on hot or flaming shortening.

Can you season cast iron with Crisco?

Yes. Crisco can season cast iron when applied in a very thin layer and heated according to a cast iron seasoning method. Expect some smoke if the oven temperature is above the shortening’s smoke point, and ventilate the kitchen.

Is Crisco healthier than butter?

Crisco and butter are different fats with different nutrition profiles, ingredients, flavors, and uses. Crisco’s product page states that its all-vegetable shortening has 50% less saturated fat than butter per tablespoon, but that does not make it a health food. Use the fat that fits the recipe and your dietary needs.

Can I mix Crisco and butter for frying?

You can mix fats for some pan-cooking and baking uses, but butter’s milk solids can burn at frying temperatures. For deep frying, regular Crisco shortening or a suitable frying oil is usually simpler than mixing butter into the fat.

Final thoughts

For home cooking, treat Crisco All-Vegetable Shortening as a medium-smoke-point fat around 360°F. It is useful for baking, controlled frying, greasing pans, and cast iron seasoning, but it should not be overheated or left unattended.

If you are frying with Crisco, use a thermometer and stay near the recipe’s target temperature. If you are seasoning cast iron, wipe the layer extremely thin and expect some smoke at higher oven temperatures. If you need more heat margin for deep frying, searing, or stir-frying, choose a higher-smoke-point liquid oil instead.
