You can season stainless steel pans to a degree by bringing oil up to its smoke point. YouTube has some tutorials.
Pan will end up fully black. I had a previous attempt where I used too much oil (then the coating ends up sticky and it smokes during the heating) the pan must really be dry again. There will still be enough oil in the surface. Used flaxseed oil.
Just use some oil and high heat before putting things in. And use a Teflon pan for more delicate things that don't need to be seared.
