Provided is a method for producing a hydroxyalkyl alkyl cellulose having high thermal gel strength while suppressing a reduction in thermal gelation temperature. More specifically， provided is a method for producing a hydroxyalkyl alkyl cellulose including steps of: mixing cellulose pulp with a first alkali metal hydroxide solution to obtain alkali cellulose， reacting the alkali cellulose with an alkylating agent and a hydroxyalkylating agent to obtain a first reaction product mixture， adding a second alkali metal hydroxide solution to the first reaction product mixture without further adding any of alkylating and hydroxyalkylating agents to obtain a second reaction product mixture， and subjecting the second reaction product mixture to purification to obtain a hydroxyalkyl alkyl cellulose.
