How to Season a Le Creuset Cast Iron Grill Pan

Le Creuset is a name that is synonymous with outstanding quality and exceptional cookware. Their cast iron grill pan is no different, being one of the most sought after cast iron grill pans in the market. However, owning a grill pan made of cast iron does not guarantee exceptional results if it is not properly cared for. If you are looking to maintain your cast iron grill pan’s longevity and ensure that all your grilled recipes come out with great flavor and texture, seasoning is one of the critical steps in the process.


Seasoning a grill pan involves treating its surface to create a non-stick layer that helps reduce sticking or friction while cooking. Another essential benefit of seasoning is it helps protect your pan from harsh substances that can cause rusting or corrode its surface. For this reason, seasoning ensures that your cast iron grill pan has an extended lifespan.

In this article, we will take you through how to season your Le Creuset Cast Iron Grill Pan using both dry and heat seasoning methods. We will also cover critical topics such as cleaning and maintaining your cast iron grill pan, testing your seasoned cookware, common issues that arise during the process, troubleshooting and much more.

What Is A Le Creuset Cast Iron Grill Pan?

Before we delve into seasoning, it is crucial to understand what the Le Creuset Cast Iron Grill Pan is and why it is so unique. Le Creuset is a French brand that produces high-quality cookware using traditional casting methods since 1925. Le Creuset products are both vibrant and durable, thanks to their highly resistant enamel finish.

The Le Creuset Cast Iron Grill Pan resembles a griddle pan with raised ridges on its surface used to sear or grill meats, fish, veggies over high heat.

The Le Creuset Cast Iron Grill Pan’s raised ridged surface guarantees even better searing results, adding those sought after grill marks to your meals.

The Different Methods of Seasoning a Le Creuset Cast Iron Grill Pan

The two main methods of seasoning your Le Creuset Cast Iron Grill Pan are dry and heat seasoning.

Dry Seasoning Using Oil Or Shortening

Dry seasoning involves applying oil or shortening to your clean dry pan’s surface and baking it in an oven for a specified period. For best results when dry seasoning your Le Creuset Cast Iron Grill Pan:

  • Use flaxseed oil as it creates an incredibly durable non-stick surface.
  • Avoid using vegetable oil as it can leave a sticky residue due to its high wax content.
  • To achieve excellent results, repeat this process several times until your grill pan feels slick to the touch.
  • The Dry seasoning method prevents smoke creation during the process.

Heat Seasoning Using An Oven Or Stovetop

The heat seasoning method involves reheating oiled cookware on medium-high heat on a stovetop until it starts smoking, indicating that a new seasoning layer has been created. Here’s how to do it:

  • Coat your Le Creuset Cast Iron Grill Pan with flaxseed oil or shortening
  • Place the pan in a preheated oven or on top of heated stove burner to apply heat evenly.
  • To achieve better seasoning, you can repeat this process several times until you are satisfied.
  • This seasoning method produces smoke, so make sure your kitchen is well ventilated.

By following the steps outlined in this article, you can enjoy your cookware’s remarkable benefits with a long lifespan while producing delicious grilled meals at home.

What is the best oil to use for seasoning a Le Creuset cast iron grill pan?

For the best results, we recommend using a high-smoke point oil such as vegetable, canola or grapeseed oil. Avoid using olive oil or butter as they have a lower smoke point and may leave a sticky residue on the pan.

How many layers of seasoning should I apply on my Le Creuset cast iron grill pan?

In order to properly season your Le Creuset cast iron grill pan, we recommend applying at least three coats of seasoning. However, you can continue to add more layers until you achieve the desired level of non-stick performance.

Do I need to preheat my Le Creuset cast iron grill pan before seasoning it?

Yes, it is important to preheat your grill pan in an oven at 400°F for about 5-10 minutes before you start the seasoning process. This allows the pores of the cast iron to open up and fully absorb the oil.

Can I use soap or other cleaning detergents on my seasoned Le Creuset cast iron grill pan?

It is not recommended to use soap or other cleaning detergents on your seasoned Le Creuset cast iron grill pan as they can strip away the oils and cause the pan to rust. Instead, use hot water and a stiff brush to remove any leftover food debris after each use.
