Cast Iron Skillet Tips:

Use Cooking Oil Spray

To ensure that your frittata comes out clean of your skillet, be sure to generously spray your cast iron pan with cooking oil spray.

Alternatively, you can coat your pan with butter, but I prefer the cooking spray because it’s easier and causes less mess.

Know How to Take Care of Your Cast Iron Skillet

Cast iron skillets can be tricky little cookware. Be sure to know how to take care of yours by reading your user manual and/or following directions specified by the brand.

For instance, my cast iron skillet is enamelled and coated, so it does not require any seasoning. However, most cast iron skillets are non-coated, therefore, they needed to be seasoned from time to time, and never washed in the dishwasher.

Be Sure to Pre-Cook Your Zucchini

To get the best texture out of your zucchini, be sure to pre-bake it so that your cast iron frittata tastes its best! This step is very important, so be sure not to skip out on it.

You can do the rest of the frittata preparation as the zucchini roasts in the oven. It’s all about multitasking!

Careful! It’s Hot!

Proceed with caution when cooking and dealing with cast iron skillets. They get very hot! This is why they’re so ideal for cooking – it offers the most even cooking when it comes to other cookware. However, you must be careful so be sure to use good quality oven mitts when taking it in and out of the oven. I prefer using silicone oven mitts for the best protection.
