Why Is My Cast Iron Skillet Smoking?

Reason 1: Excessive Heat

Cast iron skillets can handle high temperatures, but there’s a limit. When your skillet gets too hot, it can start smoking. The seasoning on cast iron pans consists of thin layers of hardened oil, and excessive heat can cause this oil to smoke.

Reason 2: Low Smoke Point Oils

The choice of cooking oil matters. Oils with low smoke points, like olive oil, can trigger smoking when exposed to high heat. This issue can also arise when cooking foods with fats that have lower smoke points, such as bacon or hamburgers.

Reason 3: Improper Cleaning

Neglecting proper cleaning can lead to sticky layers of oil building up on your skillet. Over time, these sticky residues become harder to clean and start smoking as the pan heats up.

What to Do If Your Skillet Starts Smoking?

If your skillet begins smoking during cooking, it’s essential to act promptly to prevent any unpleasant consequences.

If your skillet starts smoking during cooking:

  • Turn down the heat immediately to prevent further smoking.
  • If the smoke is excessive, remove the pan from the burner temporarily.
  • Carefully pour off any rancid oil and allow the pan to cool a bit.
  • Wipe out burnt bits and blackened oil.
  • Reheat the pan at a lower temperature, add fresh oil, and continue cooking.

How To Reduce Smoke When Cooking With Cast Iron

Here are the steps on how to prevent cast iron pans from smoking:

Step 1: Thorough Cleaning

The foundation of smoke-free cooking with cast iron is cleanliness.

Follow these steps:

  • Clean the skillet thoroughly with hot, soapy water and a soft sponge. Don’t worry; soap won’t harm it unless you resort to harsh scrubbing or abrasive utensils.
  • Once clean and dry, inspect for sticky spots, and signs of built-up oil. These spots usually occur when excess oil is repeatedly heated and not cleaned out properly.

Step 2: Selecting the Right Cooking Oil

Choosing the right oil can make a significant difference:

  • Opt for cooking oils with high smoke points, such as avocado, peanut, canola, sunflower, or grapeseed oil. These oils can handle the heat without smoking.
  • Heat the skillet to a medium temperature for a few minutes. To check if it’s ready, sprinkle a few drops of water on it; sizzling water indicates the skillet is ready. Add the chosen oil and begin cooking.
  • Keep a close eye on the skillet and adjust the heat as needed. If smoke appears, lower the burner. Remember, it takes a moment for the skillet to adapt to temperature changes.

Step 3: Adjusting Heat and Cooking

  • Always monitor and control the skillet’s heat to prevent smoking. Cast iron retains heat well but can get too hot if left unattended.

Tips on Re-Seasoning Your Cast Iron Skillet

Maintaining your cast iron skillet’s seasoning is crucial for smoke-free cooking. Here’s how to do it:

Quick Re-Seasoning

  • After cooking, clean the skillet thoroughly, using hot, soapy water if needed.
  • Place the skillet on a medium-low heat burner until completely dry.
  • While still warm, apply 1 teaspoon of oil and rub it in with a paper towel.
  • Use a fresh paper towel to wipe out excess oil; the pan should look dry, not greasy.
  • Allow the pan to cool before storing it in a cool, dry place.

Full Strip & Re-Seasoning

This is necessary when the quick re-seasoning isn’t enough or if restoring an old skillet:

  • Remove the current seasoning by running the skillet through the cleaning cycle of your oven (approximately six hours).
  • Clean the cast iron thoroughly, scrubbing away all seasoning remnants.
  • Select a high-smoke point oil for seasoning, like canola or grapeseed oil.
  • Preheat the oven to 25°F hotter than the oil’s smoke point and place the skillet inside until it’s completely dry.
  • While warm, rub a teaspoon or two of oil over the entire surface, removing excess oil with a fresh paper towel.
  • Bake the skillet upside down for an hour to create a fresh layer of seasoning.
  • After deep frying, let the skillet sit overnight at room temperature with frying oil to seal the new seasoning.
  • Clean the skillet in hot water with a soft sponge or cloth and store it after drying.
