He did this by demonstrating that maggots did not appear in meat that was fully sealed from the air.
Detailed answer:

When it comes to learning about nature and the world around us, there are many ways to go about it. One way is to study the natural world in an observational manner, by simply watching what happens as it happens. Another way is to set up experiments that attempt to explain how things work and why they happen the way they do.

Francesco Redi was an Italian physician and naturalist who is best known for his work on disproving the idea of spontaneous generation. In his experiments, he placed meat in one jar and cheese in another jar, then sealed them from air so that no flies could get into them. He found that after a few days, flies would lay eggs in the jar with the meat, but not in the jar with the cheese. From this, he concluded that flies were not spontaneously generated from meat, but rather came from eggs laid by other flies.

Redi’s work was instrumental in disproving long-held beliefs about spontaneous generation—the idea that living organisms could come into being without parents or other outside influences or agents. His experiments helped establish both science as a method of inquiry and controlled experimentation as a necessary part of scientific inquiry.
