Hello Richard. Shallow frying frozen chicken nuggets in cast iron is a wonderful method that yields a much crispier exterior than baking, while taking significantly less time.
For the exact timing, you will want to fry the nuggets for 3 to 4 minutes per side over medium heat, for a total cooking time of roughly 6 to 8 minutes. Because nuggets are being cooked directly from frozen, the safe target internal temperature required for poultry is 165 degrees Fahrenheit (74 degrees Celsius).
Here is a reliable step-by-step method to achieve an even golden crust without burning the breading:
1. Oil Level and Heat: Add about 1/4 inch of a neutral, high-smoke-point oil (such as canola, vegetable, or peanut oil) to your cast iron skillet. Preheat the skillet over medium heat until the oil reaches approximately 350 degrees Fahrenheit. If you do not have an oil thermometer, dip the tip of a wooden spoon handle into the oil; steady, gentle bubbling around the wood indicates it is ready.
2. Do Not Overcrowd: Place the frozen nuggets into the pan in a single layer with a little space between each piece. Overcrowding drops the oil temperature rapidly, which makes the breading absorb oil and turn greasy instead of crisping.
3. Cooking and Turning: Let the nuggets fry undisturbed for 3 to 4 minutes on the first side. Once the bottom is golden brown, turn them over using tongs and fry for another 3 to 4 minutes on the reverse side.
4. Temperature Check: Before removing the batch, insert an instant-read digital thermometer into the center of the largest nugget to verify it has reached 165 degrees Fahrenheit.
5. Draining: Remove the nuggets and place them immediately on a wire cooling rack set over a baking sheet, or on a paper towel-lined plate. Elevating them on a wire rack allows steam to escape from all sides, keeping the bottom crust crisp.
I hope this guide helps you get delicious, perfectly crisp nuggets every time.
