We present an effective theory framework to understand the properties of matter at temperatures around the QCD crossover. Assuming that an effective theory of quarks is applicable here, we write down all terms consistent with the symmetries, up to mass dimension $6$. We treat this theory in the mean field approximation. We fix the parameters of the theory by matching values of two static pionic properties with those measured on the lattice. We calculate other observables from the model and obtain encouraging agreement with lattice results. The analytic continuation of the fermionic theory can be used to study dynamic properties near the crossover.
