🔧 How to Season Cast Iron Cookware
Take care of your cast iron, and it will take care of your cooking—for generations.
There are two simple ways to maintain the seasoning on your cast iron cookware:
- Use it regularly — Every time you cook with oil, you naturally reinforce the seasoning layer. This is the easiest and most effective method to build and maintain a nonstick surface.
- Oven season it occasionally — For a more thorough refresh, seasoning your cast iron in the oven ensures a strong, even coating over the entire surface.
🔄 When Should You Re-Season?
Seasoning can wear down over time, especially after:
- Cooking acidic foods (like tomatoes or vinegar-based sauces)
- Scrubbing too hard with steel pads or abrasives
- Leaving the pan to soak in water
- Not drying it thoroughly after washing
Re-seasoning restores the smooth, black finish and protects the pan from rust. If your cast iron looks dull, sticky, or slightly rusty, it’s time to season it in the oven.
🔥 3 Easy Steps to Oven Seasoning
✅ Step 1: Scrub
Wash your pan with warm, soapy water and a scrub brush. Dry it completely with a towel.
💡 Soap is okay here because you're about to re-season the pan.

✅ Step 2: Apply Oil
Rub a very thin, even layer of cooking oil over the entire pan—inside, outside, and handle too. Avoid over-oiling; excess oil can cause a sticky surface.
💃 Recommended oils: Canola, flaxseed, vegetable, or grapeseed oil.

✅ Step 3: Bake
Place the pan upside down on the middle rack of your oven. Put a baking sheet or foil underneath to catch drips. Bake at 450–500°F (230–260°C) for 1 hour, then turn the oven off and let the pan cool inside.

🧠 What Is Cast Iron Seasoning?
Seasoning is simply oil baked onto cast iron, creating a black, protective finish that:
- Prevents rust
- Builds a natural nonstick layer
- Improves the more you use it
This process is called polymerization, and it’s what gives your cast iron that signature smooth sheen.

How does Crovora season its cast iron cookware?
At Crovora, we season our cookware with a high-quality soy-based vegetable oil. Each piece is lightly coated and baked at high heat to form a natural, protective layer that enhances performance from the first use.
We never use synthetic chemicals, animal fats, or additives—just pure, plant-based oil that is allergen-safe and kosher-friendly. This process not only preserves the integrity of your cookware but also builds a foundation for excellent non-stick results.
Some variation in the seasoning's appearance is normal and will even out with continued cooking, improving with every meal you make.
FAQs About Crovora Seasoning
Yes! We use a soy-based vegetable oil that is Kosher-certified. While our oil meets Kosher requirements, our manufacturing facility is not currently Kosher-certified.
Our soy oil goes through a high-temperature refining process that removes all GMO-related proteins. Independent testing confirms no GMO markers remain in the final product.
Yes. Our seasoning oil is refined to eliminate proteins that may cause allergies or inflammation. Still, you can re-season your cookware with any high-smoke-point oil of your choice at home.
It’s best to wait until your seasoning is well established. Acidic foods can erode new seasoning, but over time your pan will handle them better.
This is normal. When seasoning is stressed by high heat or acid, it may release harmless residue. It fades with use and regular maintenance.
This is from the seasoning oil pooling during baking. It’s not a defect—just excess oil that carbonized. It will smooth out over time.
Yes. Slight inconsistencies in seasoning are normal and will blend with continued use. They do not affect performance.
This can happen if a layer didn’t fully bond. Scrub, dry thoroughly, apply oil, and re-bake to rebuild a smooth protective surface.
The texture is from the casting mold and helps seasoning stick. As you use your cookware, it will naturally smooth out. Light sanding and re-seasoning can speed up the process if you prefer a silky finish.
