We study the existence of everywhere differentiable functions which are almost everywhere solutions of quite general Hamilton-Jacobi equations on open subsets of or on -dimensional manifolds whenever . In particular, when is a Riemannian manifold, we prove the existence of a differentiable function on which satisfies the Eikonal equation almost everywhere on .
