Idea

An E E_\infty-monoid (or E-infinity monoid object) in a symmetric monoidal model category CC is an algebra over an operad over the E-infinity operad. Assuming that CC is cofibrantly generated, there is a model structure on E E_\infty-monoids, given by the model structure on algebras over an operad over the E-infinity operad (which is cofibrant). This model category presents the (infinity,1)-category of commutative monoids in a symmetric monoidal (infinity,1)-category (in the symmetric monoidal (infinity,1)-category presented by CC).

Rectification

In some symmetric monoidal model categories, E E_\infty-monoids can be rectified to (strictly) commutative monoids in a symmetric monoidal model category. See there for more.
