For best results, place the sealed package in the refrigerator to thaw about half a day before your meal - overnight if you want it for lunch, in the morning if it’s for dinner. If your plans change, the chilled and still sealed package will last up to 3 days in the refrigerator. If you’re in a hurry, just get the package from the freezer and place it in lukewarm water for about 20 minutes.
Open and discard the package and put the gnocchi in a pan to reheat (stove on low-medium heat, stir occasionally, about 8 minutes). Alternatively, put on a plate and reheat in the microwave (800W for 5 minutes). Add a little water if needed.
