Seasoning Cast Iron With Crisco: The Ultimate Guide to a Nonstick Finish

When it comes to cast iron cookware, the secret to achieving a smooth, nonstick surface is in proper seasoning.

In this article, we’ll explain exactly how seasoning cast iron with Crisco can achieve that perfect black patina.

So, let’s get started and walk through each step of how to season a cast iron skillet with Crisco and why it is a trusted favorite of mine for this process. You can see how it is done here.

Why Seasoning Cast Iron Is Necessary

Seasoning is the process of bonding a thin layer of oil or fat to the surface of your cast iron through heat and time. This process is called polymerization.

If the type of oil you use and the amount of heat combined with the length of time do not cause your cast iron to polymerize properly, you will end up with a sticky mess or a splotchy finish at best.

That is why following a proper seasoning technique is so important for creating a natural, nonstick coating and protecting the skillet from rust, too. If you need additional help along the way, be sure to check out our Cast Iron for Beginners guide.

Key Benefits of Seasoning

• Rust Prevention: The baked layers of oil protect the metal from moisture, thereby preventing rust from forming.
• Nonstick Cooking: Proper seasoning makes your skillet slick, eliminates sticking, and allows food to slide right out of the pan.
• Durability: Proper seasoning also guarantees your cast iron lasts for generations.

What Does Properly Seasoned Cast Iron Look Like?

A well-seasoned cast iron skillet should have a smooth, slightly shiny surface that feels slick to the touch. Depending on its age and use, the color will range from dark brown to black.

Why Use Crisco for Seasoning Cast Iron?

Crisco is a vegetable shortening and is a popular choice for seasoning cast iron. Here’s why:

• High Smoke Point: Crisco has a high smoke point, making it ideal for seasoning.
• Ease of Use: Its semi-solid form versus a liquid makes the application nearly mess-free.
• Reliable Finish: In my experience, Crisco consistently produces a smooth, even layer of seasoning.

Step-by-Step Guide To Seasoning Cast Iron With Crisco

• Step 1: Clean Your Skillet
  Before you start, preheat your oven to 450 degrees, and then make sure your cast iron is clean. As important as seasoning your cast iron is, proper cleaning is the most fundamental step to achieving a fool-proof base layer of seasoning.
  Here’s how: Wash the skillet with warm water and mild dish soap (like Dawn). If this doesn’t completely clean it, then Scrub off any rust or food residue using a salt and oil paste while heating the skillet on the stovetop. Rinse thoroughly and dry completely. You can then reheat it briefly on the stovetop to ensure it’s bone-dry.
• Step 2: Apply Crisco
  Now it’s time to apply the Crisco:
  Scoop a small amount of Crisco (about a tablespoon for a skillet). It may take a bit more to completely cover the entire skillet, top and bottom, inside and out.
  Using your fingers, a paper towel, or a cloth, rub the Crisco over every surface, inside and outside, and pour spouts and handles.
  Make sure every nook and cranny is covered. If you don’t, this will cause you to have an uneven finish.
  Wipe off the excess oil. Less is more here; too much oil will create a sticky mess if you bake it without removing ALL of the excess! When you think you have it wiped down, wipe it down one more time, trust me!
• Step 3: Bake The Skillet
  Make sure your oven is preheated to 450°F.
  Place the coated and wiped-down skillet upside down on the middle rack of the oven. Use a liner or foil on the bottom rack to catch any possible drips. If you have wiped it down completely, you shouldn’t have any drips.
  Bake the cast iron skillet for 15 minutes, then remove it and wipe off any excess oil once again. Be careful because it is HOT! I use an Ove Glove or a couiple of potholders to remove and replace the skillet back into the oven once I know it is completely free of any excess oil. This is crucial to ensure you don’t end up with a sticky mess! DO NOT SKIP THIS STEP!
  Return the skillet to the oven and bake for another hour to an hour and a half. Once the hour is up, turn the oven off and let the cast iron pan cool down naturally.
• Step 4: Let It Cool
  Allowing the skillet to cool down naturally in the oven does three things: It helps the oil cure properly, solidifies the seasoning, and prevents uneven spots.
  I like to start my seasoning process late in the evening so that when it is done, it can cool down overnight. If you are doing more than one round of seasoning, you want to make sure it is completely cool before starting the next round.

Common Mistakes To Avoid When Using Crisco For Seasoning

Even with the best intentions, mistakes can happen. Here’s what to avoid:

• Using Too Much Crisco
  Applying too much Crisco leads to sticky or splotchy seasoning. ALWAYS wipe off the excess.
• Not Heating The Pan Properly
  Reaching at or near the oil’s smoke point is important for proper bonding. Make sure your oven is set at the right temperature. In my experience, 450 degrees for Crisco is perfect.
• Skipping The Cleaning Step
  Make sure the skillet is clean and dry before applying the Crisco. Trying to season a dirty cast iron skillet is useless and is a waste of your time. Dirty cast iron compromises the seasoning process, so make sure it is completely clean before you start.

Maintaining Your Seasoned Cast Iron

• Daily Care Tips
  Hand wash and wipe the skillet clean after each use.
  Dry completely. Apply a light coat of Crisco all over before storing.
  Avoid soaking your cast iron, and NEVER put it in the dishwasher!
• When To Reseason Your Skillet
  Even though most cast iron skillets come preseasoned, if your skillet has grayish spots, starts sticking, or shows signs of rust, it’s time for another round of seasoning.

Alternative Seasoning Methods

While Crisco is one of my favorites, you can experiment with other methods for seasoning to see what works best for you.

Using Avocado Oil

Avocado oil has the highest smoke point, at 520 degrees. This high-smoke-point oil is another one of my options for a long-lasting seasoning layer.

Stovetop Seasoning

For quick seasoning, apply oil and heat the skillet on the stovetop. Be careful of uneven results compared to oven methods.

Why Flaxseed Oil Isn’t Recommended

Although this is a popular recommendation found on the internet, I do not recommend flaxseed oil. It is prone to flake off and chip.
