Why are leftovers from a hot meal always tastier than the original meal when they are heated up the next day?

Not all leftovers improve with time. Certain dishes, especially those with delicate textures or ingredients that degrade quickly, may not fare as well after reheating. However, a number of factors can contribute to an enhanced flavour profile when reheating stews, casseroles, curries and similar dishes.
As a dish sits, the flavours have more time to meld together. This can result in a harmonious and balanced taste, as the different ingredients have had more time to infuse their flavours into the entire dish.
Leaving the dish to sit also allows the flavours to penetrate and marinate the ingredients more thoroughly. This can enhance the overall taste and make the dish more flavourful.
Some chemical reactions, such as Maillard browning, continue to occur even after cooking. When you reheat the leftovers, these reactions can lead to the development of new and complex flavours, making the dish more delicious.
There is also a psychological aspect to the perception of taste. Anticipation and the memory of a delicious meal can contribute to the perception that leftovers taste better.
The positive experience associated with the initial meal can enhance the enjoyment of the reheated leftovers. For me, pizza is always best the day after – it reminds me of the halcyon days of university.

I can think of two reasons. One is that the flavours have had time to blend together.
The other is that, if you are the cook, smelling the flavours of the meal while you are cooking it desensitises you to its full taste. The next day, you come fresh to it and can taste it properly.
