Do I need to adjust slow cooker recipes for high altitude?
It really depends on the length of time recommended. Due to the usual long length (>4 hours) of slow-cooker recipe cook times most elevation differences would be negligible. However if a recipe calls for a cook time of less than 4 hours you may see some foods not cooking as usual. Legumes might especially be sensitive to this as they take a very long time to cook completely. Below is a table from Wikipedia on elevation vs water boiling temperatures.



Altitude, m Boiling point of water, °C

(0ft)   100 (212°F)

(984.25ft)  99.1 (210.3°F)

(1968.5ft)  98.1 (208.5°F)

(3280.8ft)  96.8 (206.2°F)

(6561.68ft) 93.3 (199.9°F)

(13123.36ft)    87.3 (189.1°F)

(19685.04ft)    81.3 (178.3°F)

(26246.72ft)    75.5 (167.9°F)



You may need to experiment with longer cook times for foods that you are having trouble with.
