2. Setup & Initial Seasoning
Before first use, it is crucial to properly clean and season your de Buyer MINERAL B Carbon Steel Fry Pan to ensure optimal performance and develop its natural non-stick properties.
Initial Cleaning:
- Handwash the pan with hot water and a soft sponge to remove the protective beeswax coating.
- Dry the pan thoroughly immediately after washing to prevent rust.
Seasoning Process:
- Pour a thin layer of cooking oil (preferably with a high smoking point, such as grapeseed, canola, avocado, or vegetable oil) into the pan, covering the bottom and sides.
- Gradually heat the pan on medium-high heat for approximately 10 minutes, or until the oil begins to smoke.
- Allow the pan to cool down completely.
- Drain any excess oil and wipe the pan dry with a paper towel.
- Reheat the pan to medium-high for 2 minutes.
- Repeat steps 1-5 several times to build up a robust seasoning layer. The pan will darken over time, indicating a well-seasoned surface.

3. Operating Instructions
Heat Management:
- Carbon steel heats up quickly and retains heat efficiently. Start with medium heat and adjust as needed.
- Avoid extremely high heat for extended periods, especially when the pan is empty, to prevent warping.
- Preheat the pan gradually before adding food to ensure even cooking and prevent sticking.
Cooking Surfaces:
The pan is compatible with all cooking surfaces, including gas, electric, and induction cooktops. It is also oven safe for short periods (up to 10 minutes at 400°F) for finishing dishes.
Recommended Cooking:
- Searing: Excellent for achieving a perfect crust on meats and fish.
- Sautéing: Ideal for vegetables and other ingredients that benefit from high, even heat.
- Eggs: A well-seasoned pan will allow eggs to slide off easily.
Foods to Avoid:
Avoid cooking highly acidic foods (e.g., tomatoes, lemon juice, wine) in your carbon steel pan, especially when it is new or not fully seasoned. Acidic ingredients can strip the seasoning and lead to rust.

4. Maintenance
Cleaning After Use:
- Allow the pan to cool slightly before cleaning.
- Handwash only. Avoid harsh soaps or detergents, as they can strip the seasoning. Use hot water and a stiff brush or non-abrasive sponge to remove food residue.
- For stubborn stuck-on food, deglaze the pan with hot water while it's still warm, scraping with a wooden or silicone spatula.
- Dry the pan immediately and thoroughly after washing. You can place it on low heat on the stovetop for a minute to ensure all moisture evaporates.
Re-seasoning:
If your pan starts to stick or shows signs of rust, it may need re-seasoning. Follow the initial seasoning steps outlined in Section 2. Regular light re-seasoning after cleaning can help maintain the non-stick surface.
Storage:
Store the pan in a dry place. If stacking with other cookware, place a paper towel between pans to prevent moisture buildup and potential rust.
5. Troubleshooting
Food Sticking:
- Ensure the pan is properly preheated before adding food.
- Verify that the pan has a sufficient layer of seasoning. If not, re-season the pan.
- Use a small amount of cooking oil or fat when cooking.
Rust Formation:
- Rust occurs when moisture is left on the pan. Always dry the pan immediately and thoroughly after washing.
- If rust appears, scrub it off with a steel wool pad or abrasive sponge, then wash, dry, and re-season the pan.
Warping:
- Carbon steel can warp if exposed to sudden temperature changes (thermal shock). Avoid plunging a hot pan into cold water.
- Heat the pan gradually and avoid using excessively high heat for prolonged periods, especially when empty.
