Higgs bosons from an extended Higgs sector, such as a two-Higgs-doublet model, can have greatly enhanced coupling to the bottom quark. Producing such a Higgs boson in association with a single high-${p}_{T}$ bottom quark via $g\stackrel{\ensuremath{\rightarrow}}{b}\mathrm{hb}$ allows for the suppression of backgrounds. Previous studies have instead used $gg,q\overline{q}\ensuremath{\rightarrow}b\overline{b}h$ as the production mechanism, which is valid only if both b quarks are at high ${p}_{T}.$ We calculate $g\stackrel{\ensuremath{\rightarrow}}{b}\mathrm{hb}$ at next-to-leading order in QCD, and find that it is an order of magnitude larger than $gg,q\overline{q}\ensuremath{\rightarrow}b\overline{b}h$ at the Fermilab Tevatron and the CERN Large Hadron Collider. This production mechanism improves the prospects for the discovery of a Higgs boson with enhanced coupling to the b quark.
