The quick answer
Plain frozen chicken can be cooked in an oven or on the stove using a suitable method, but it commonly takes about 50% longer than thawed chicken. Check every piece reaches 165°F / 74°C at its thickest part. Do not cook frozen raw chicken in a slow cooker; follow package instructions for prepared products.

Check what you are starting with
Frozen breaded chicken can look browned while still being raw. Read whether the product is raw, partly cooked or ready to eat, and use the appliance and method named on the label. A general fresh-chicken recipe does not override product-specific instructions.
For plain raw pieces, frozen-solid clumps cook less evenly than separated pieces. Do not force a knife between frozen pieces. Thaw safely in the refrigerator if you cannot separate and arrange them without damage.
Plan a suitable oven or stovetop cook
Choose a tested method
Use instructions written for frozen chicken and the specific cut, or the package directions. Breast, thigh and whole-bird timings are not interchangeable.
Arrange for even heat
Place suitable pieces separately as the method specifies. Account for frozen packaging, pads or giblets: anything not intended for cooking must be removable before using that method.
Allow extra time
About 50% longer is a planning estimate, not a final timer. Keep cooking until the temperature is reached, protecting an over-browning outside if the recipe permits.
Check several locations
Use a thermometer at the thickest part, avoiding bone and the pan. Check multiple pieces, not only the smallest. The safe poultry endpoint is 165°F / 74°C.
When thawing is the better choice
Thawing in the refrigerator gives more even seasoning and easier portioning. Keep chicken in a leakproof container on a low shelf. Cold-water thawing requires a leakproof bag, cold water changed regularly and immediate cooking; microwave-thawed chicken also needs immediate cooking.
Do not thaw chicken on the counter or wash raw chicken under the tap. Keep raw juices away from salads, utensils and food that will not be cooked. Clean contacted surfaces and wash hands before handling ready-to-eat food.
Methods and shortcuts to avoid
Do not put frozen raw chicken into a slow cooker. Do not use a microwave to cook raw frozen chicken unless following an appropriate authoritative product method; the general safe route is thawing first and cooking immediately. For a frozen packaged meal, follow its own validated directions.
An air fryer or grill is not automatically interchangeable with an oven. A crisp exterior or clear juices do not establish a safe center. Recheck with a thermometer and stop relying on color alone.
A few useful answers
Is 50% extra time always enough?
No. It is a planning estimate. Size, cut and starting state vary; the temperature reading decides when poultry is done.
Can I put frozen chicken straight in a slow cooker?
No. Thaw safely first and follow a suitable slow-cooker recipe.
