•Surrogate model of magnetic confinement equilibrium with stochastic parameters.•The surrogate function bypasses the solution of the free boundary problem.•Sparse grids in parameter space reduce the cost of tensor product grids.•Reduction of the time for Monte Carlo simulations by factors between 7 and 30. |
