Aircraft was fueled to 11.0; which was 400 pounds above minimum planned. We were advised five minutes prior to push of a wheels up time. Pushed on time and taxied single engine. Ground advised departure time extended. Started remaining engine and departed. First indication that I missed the fuel check was at level off when FMC indicated 'Using Reserve Fuel'. We landed with 5.9 of fuel. I normally recheck the fuel prior to departure. Since we were already 400 pounds over planned and taxied single engine; my expectation bias was that we were good on fuel. I will be more deliberate in my fuel check habit pattern.
An Air Carrier pilot reported departing with less than minimum takeoff fuel due to ATC delays while taxiing.
