With dozens of good-quality cooking oils to choose from, picking oil to season your cast-iron can be a tough decision. Here's our guide to all things seasoning oil so you can learn the pros and cons of each oil type and start building a beautiful season on your favorite cast-iron pieces. Seasoning cast-iron refers to applying a thin layer of cooking oil to its surface to fill the tiny pores that are naturally a part of any cast-iron pan, pot, or skillet. If you're at all familiar with the material, you may have heard mention of seasoning cast-iron. Unlike non-stick coated and steel pans, a cast-iron pan needs seasoning before you use it. Otherwise, you'll find it impossible to lift any food off of its surface. Some cast-iron cookware comes pre-seasoned, which is a handy feature. You can still season them again to promote the coating's longevity and durability, but it's completely optional. For those that come unseasoned, you'll want to do it yourself at home before you even think of using your cast-iron pan. Why do you need to season your cast-iron cookware?
Benefits of Cast-Iron CookingThough it requires an initial seasoning which can be a bit more work, our cast-iron tools are our go-to for cooking almost every meal we make. Here's why:
For the last decade or so, word on the street is that flaxseed oil cast-iron seasoning is the very best gold-standard from a scientific perspective. While we don't think it's the bad choice, with its low smoke point, but we're not convinced that flaxseed oil is the very best cast-iron oil, either. Pros
Cons
#2: Grapeseed Oil - An All-Around WinnerWhile this oil might not get the same hype as flaxseed, grapeseed oil is our personal #1 when it comes to choosing your very best oil for cast-iron seasoning. It tastes good with most flavors and boasts a much higher smoke point. Pros
Cons
#3: Canola Oil - Cheap and Gets the Job DoneCanola oil is dirt-cheap to buy and is handy in plenty of recipes, so you likely already have a bottle stashed in your pantry. While canola will get the job done, its results aren't as good for seasoning cast-iron. Flaxseed oil and grapeseed oil both get you better results, but you'll pay a premium for them, too.
We can see why seasoning cast-iron with coconut oil might seem like a great idea, but there are plenty of better oil options on the market. Don't get us wrong, coconut oil is delicious - it's our oil of choice for making cookies and Thai-style curries, and we even use it for body lotion! While the health benefits of virgin coconut oil are undeniable, it's not a great option to season cast-iron with coconut oil because of its saturated fat content. Pros
Cons
#5: Peanut Oil - Tastes Too, Well, Peanut-yPeanut oil is prevalent for stir-frying and in Asian cooking, but we don't think it makes the best seasoning for cast iron, as it has a powerful peanut flavor that doesn't always blend well with every meal you cook. Pros
Cons
#6: Vegetable Oil - Cheap But Less DurableVegetable oil is almost identical to canola oil, and you can usually use the two interchangeably. This means that like canola oil, using vegetable oil for seasoning your cast-iron is a cheap option but won't give you the best results.
Many vegetable oils contain sunflower oil in their blend, making results very similar to canola or vegetable blends. Pros
Cons
#8: Avocado Oil - A Hardened Coat of (Expensive) ArmorAvocado oil, much like the fruit it comes from, is full of heart-healthy unsaturated fats; but should we use avocado oil for seasoning cast-iron? We think so! The polymerization of the fats in avocado oil will give you a solid and durable seasoning on all your favorite pans. The one drawback to seasoning cast-iron with avocado oil is its price. Pros
Cons
#9: Olive Oil - Stay Far, Far AwayOne thing you should never, ever attempt is seasoning a cast-iron skillet with olive oil. Olive oil has many health benefits when enjoyed uncooked or in low-heat cooking. With its exceptionally low smoke point, trying to use olive oil to season cast-iron the traditional way will end with burning carcinogens floating into the air. While you can try to season cast-iron with olive oil by doing more seasoning sessions at a lower temperature, it seems labor intensive with less predictable results. Pros
Cons
Best Oil to Season a Cast-Iron Skillet - FAQWhat is the best oil for cast-iron cooking?Once your pan is seasoned, you'll want to drizzle in a small amount of oil as you cook, just as you would with any other pan. The best oil for the job largely depends on what you're making and which tastes you prefer. One thing to keep in mind is the smoke point - if you're cooking over high-heat, a low smoke point oil will burn and release potentially harmful carcinogens. For low-heat cooking, you have a more comprehensive range of safe options. How often should I season cast-iron?Once you establish the initial coat of seasoning on your cast-iron cookware, you can start cooking with relative ease - don't worry about the seasoning too much. With proper use, seasoning cast-iron, again and again, should be unnecessary, as the seasoning will naturally build as you cook. Re-season a cast-iron skillet or pan only if food begins to stick to it easily, it develops rust spots, or loses its shiny, smooth patina. How many times should I season my cast-iron skillet?You should repeat the initial seasoning process three or four times - while the initial layer is just your jumping-off point and your season will improve and strengthen over time, food will stick to the pan too easily with just a single coat of seasoning. Once you get past the initial process, you'll know how to season cast iron, and re-seasoning anything from pans to pie irons will be much easier. When you re-season, once is enough. The frequency of re-seasoning depends on how often you use your utensils, and it may wary from one piece of cookware to another. The more you use it, the less maintenance it needs. If you have a trusty Dutch oven for weekly stews and roasts, the oils used in cooking will keep the non-stick layer on for longer. But a pie iron that's been sitting aside throughout the cold season may need some more serious re-seasoning once you get back to it. Ultimately, it's time to re-season when the food starts sticking to the surface. Your oil needs to hit high heat to fuse to your pan and provide a smooth, non-stick coating. Place your oiled cast-iron pan into an oven and heat to 450°F, then leave it there for 30 minutes. Turn off the heat and leave your pan in the oven to cool to achieve a better season and avoid touching the burning hot cast-iron. Verdict: Which Oil is Best to Season Your Cast-Iron?After weighing the pros and cons, our personal top choice is a two-way tie: grapeseed oil and avocado both make the best cast-iron seasoning options. While you can't go wrong, either way, our financial sense pushes us a little further toward the grapeseed oil because a bottle costs a little bit less than avocado oil.
