Seasoning a cast iron pan is a crucial step in preparing the cookware for use. The process involves coating the pan with a carbonized layer of oil or animal fat, such as lard, to fill in the porous surface and create a natural non-stick barrier. This not only prevents food from sticking but also inhibits rust, a common issue with cast iron. While vegetable oils are a popular choice due to their higher smoke point, lard has been traditionally used for seasoning cast iron and remains a viable option, as long as it is properly heated and applied to a clean, dry pan.

How to season a cast iron pan with lard
Yes, you can use lard to season a cast-iron pan. Here is a step-by-step guide on how to do it:
First, ensure your cast-iron pan is clean and very dry before seasoning. If your pan is rusty, scrub it with steel wool. If steel wool is not doing the trick, place your pan in a self-cleaning oven for the shortest time allowed, then wipe it clean. If you don't have a self-cleaning oven, coat your pan with oven cleaner, put it in a plastic bag, and leave it overnight. Clean it in the morning.
Once your pan is prepared, grab some lard. The amount of lard you need depends on your pan. Pour about a tablespoon of lard into the pan and wipe it around until the top side of the pan looks wet. Then, flip the pan over, pour a teaspoon of lard onto the logo on the back, and spread it over the back and sides. Don't forget the handle! Then, wipe the pan clean. If you have a bare cast-iron pan, it will suck up the oil, so add enough lard until it looks wet and slick, then buff it until it looks dry.
Now, place your pan in the oven, upside down, over tin foil. This will allow the extra lard to drip off. Set your oven to 500°F and leave the pan in for 1 hour. Some people suggest leaving it for an extra 15 minutes for best results. If you don't have an oven, you can also rub lard on a hot pan and throw it into an open fire for several hours, as some people's grandmothers did in the past.
Your cast-iron pan is now seasoned! You can wash it after seasoning, contrary to a common misconception. However, be aware that if your pan is going to sit for a while without being used, the lard could become rancid.

The pros and cons of using lard
Lard is rendered pork fat, typically obtained from the pig's belly or around its internal organs. It is a popular choice for seasoning cast iron pans due to its mild flavour and texture-enhancing properties. It is also relatively unsaturated compared to other options and is readily accessible.
Pros of using lard:
- It has a mild flavour and texture-enhancing properties, making it a great choice for baking.
- It is rich in fat-soluble vitamins and offers a balanced fatty acid profile with health benefits when sourced from pasture-raised pigs.
- It is relatively unsaturated compared to alternatives available before the mechanical extraction of vegetable oil.
- It is inexpensive, costing around $2 for a pound at the grocery store.
- It is easily accessible and has been used for generations to season cast iron pans.
Cons of using lard:
- It has a lower smoke point compared to other fats like tallow (rendered beef fat). If the pan is not used frequently, the lard could turn rancid.
- It may not be suitable for those who are vegan or vegetarian.
- Some people may find the smell of lard unpleasant.
- It may not be as easily available as vegetable oils.
Overall, lard is a good choice for seasoning cast iron pans due to its mild flavour, texture-enhancing properties, and accessibility. However, it may not be suitable for everyone due to its animal-based origin and potential to turn rancid if not used frequently.

How to clean a cast iron pan before seasoning
To clean a cast iron pan before seasoning, you should first wash the pan by hand with a small amount of mild dish soap or detergent, hot water, and a non-abrasive sponge or scrub brush. You can also use a pan scraper to remove stuck-on food. Rinse the pan with warm water and ensure that it is thoroughly dried with a lint-free cloth or paper towel.
If there is stubborn, stuck-on food, you can simmer a little water for 3-5 minutes and then use the scraper after the pan has cooled. Alternatively, you can use coarse salt as an abrasive to scrub away food residue. If there is a lot of residue, you may need to repeat the process.
If your cast iron pan has rust, use a wire brush, metal scouring pads, or steel wool to scrub it off. You can also place the pan in a self-cleaning oven for a short period or coat it with oven cleaner, put it in a plastic bag, and leave it overnight.
Once your cast iron pan is clean and thoroughly dry, it is ready for seasoning.
Yes, you can use lard to season a cast iron pan. In fact, lard was traditionally used to season cast iron cookware before the development of mechanical extraction of vegetable oil. Lard is preferred by some over vegetable oils as it is relatively unsaturated and will not become sticky or develop off-flavors.
To season a cast iron pan with lard, rub a thin layer of lard onto the surface of the pan, including the handle and the outside. Then, place the pan upside down on the top rack of an oven preheated to 450-500°F (230-260°C) with a baking sheet or aluminum foil on the bottom rack to catch any drippings. Leave the pan in the oven for 1-1.5 hours.
You can also season a cast iron pan by heating it on a stovetop or open fire. Simply rub lard onto the pan and heat it for several hours.

The best alternatives to lard
Lard is a popular choice for seasoning cast iron pans, but it is not the only option. If you are looking for alternatives, there are several other products that can be used to season your cast iron cookware effectively. Here are some of the best substitutes:
Vegetable Shortening
Vegetable shortening, such as Crisco, is a popular alternative to lard. It is a solidified vegetable oil that can be used in a similar way to lard. It is cheap and readily available, and suitable for vegetarians and vegans. However, some people find that it leaves a sticky residue on the pan.
Vegetable Oils
Vegetable oils, such as canola oil, sunflower oil, or soybean oil, are another good option for seasoning cast iron. They are inexpensive and easy to find in most grocery stores. Vegetable oils have a high smoke point, which means they can withstand high temperatures without smoking or burning.
Flaxseed Oil
Flaxseed oil is a drying oil that can give your cast iron pan a beautiful dark finish. However, it tends to be more expensive than other options and may not be as durable, as it can flake off over time.
Coconut Oil
Coconut oil is a lesser-known alternative to lard but can be effective for seasoning cast iron. It has a lower smoke point than some other oils, so it may not be suitable for very high-heat cooking.
Beeswax
Beeswax is another option for seasoning cast iron, and it can be combined with coconut oil to make a homemade seasoning paste. However, some people find that beeswax forms an unstable layer on the pan that is softer than the layer formed by animal fats or vegetable oils.
These alternatives to lard can help you achieve a well-seasoned cast iron pan that is non-stick and ready for cooking. Each option has its own advantages and considerations, so choose the one that best suits your needs and preferences.

The best temperature and duration for seasoning
Yes, you can use lard to season a cast-iron pan. In fact, lard was the go-to fat for seasoning cast iron before the mechanical extraction of vegetable oil was developed.
Some sources suggest a slightly lower temperature of 225–250 °F for 2 hours. This lower temperature allows the pores in the skillet to open up so that the lard can penetrate the iron. If the temperature is too high, the lard will solidify on the surface of the pan, creating a brown mess that will need to be scraped off.
It is also important to ensure that the cast-iron pan is clean and very dry before seasoning. If the pan is rusty, scrub it with steel wool or place it in a self-cleaning oven for the shortest time period allowed.
Once the pan is seasoned, it can be washed and used for cooking anything.

Frequently asked questions
Yes, lard is a good option for seasoning cast iron pans.
First, clean the pan with warm, soapy water and a stiff brush. Rinse it thoroughly and dry it with a paper towel or lint-free cloth. Next, coat the interior of the pan with a thin layer of lard, using about a tablespoon for the inside of the pan and a teaspoon for the back and sides. Place the pan upside down on the middle rack of an oven preheated to 225–250 °F (107–121 °C) and bake for 1–2 hours. Leave the pan in the oven to cool for 30 minutes.
The surface of cast iron is highly porous, so food can stick to it. Seasoning fills these holes with oil, which binds to the iron and creates a protective coat that prevents food from sticking and inhibits rust. While vegetable oils have a higher smoke point than lard, lard rarely causes "slag" (a brown mess of solidified oil).
Alternatives to lard include vegetable oil, flaxseed oil, peanut butter oil, Crisco, bacon grease, and sheep or beef tallow.
If you wash and dry your cast iron pan thoroughly after each use, you shouldn't need to reseason it more than once a year, or even less.
