A soup that has been overseasoned, as occurs when one puts too much thyme in it, can be remedied by diluting the soup or by adding more bulk to it. When overseasoning involves strong or hot spices, the flavors can also be balanced by adding complementary or balancing flavors.
To correct a soup with too much thyme, add extra broth, coconut milk, cream or water to dilute the extra thyme. By increasing the soup's volume, the extra thyme is spread out and becomes less overpowering. Another solution is to add neutral grains such as rice or beans to the soup to help soak up the extra flavor.
