Rebuilding a collapsed stairs with stone slabs

My outdoor stairs were built about 10 years ago but the foundation underneath them was already failing so the whole structure has completely collapsed now. Unfortunately, we left neglected. I know I have to start by completely removing the old, broken foundation and then I need to figure out the best way to rebuild the steps to support my individual stone slabs.

I have heard that the form and pour method is excellent for foundations and stairs but I am not sure if that technique can be used when you plan to lay stone or brick on top of it. What is the most durable and easiest method for building a new, solid base for stairs that have a stone slab finish?

Should I build a basic concrete foundation using forms first and then mortar the stone slabs onto that or is there a way to form and pour the steps that directly incorporates the bricks or stone as the finishing layer?
 
I agree with @bear pickles! You need to build a solid concrete foundation. The two step method of concrete foundation followed by stone installation is highly recommended for your project. Good luck!
