Extreme heat, extreme pressure, and millions of years.
Fossil fuels are produced from the remains of ancient organisms, such as plankton and plants, that were buried and subjected to heat and pressure over millions of years. The two main things needed are organic matter (such as dead plants and animals) and the right geological conditions for burial and transformation.
Fossil fuels wwwwwwwere once living plants and animals. If they were plants they got their energy from the sun, and if they were animals they got their energy from eating plants who got their energy from the sun, or from eating animals who ate animals who ate plants who got their energy from the sun.

The sun´s energy is stored in living beings, in plants and the animals that eat the plants, and if conditions are right, that energy is then stored in the form of fossil fuels.
