FAQ

Can I use regular potatoes instead of Idaho potatoes?

Yes, but Idaho potatoes hold their shape better during long cooking. Yukon Gold are the best substitute as they're less likely to fall apart than russets.

Can I cook this on LOW instead of HIGH?

Yes, cook on LOW for 6 hours instead of 3 hours on HIGH. The texture will be slightly more tender with longer cooking.

Can I freeze leftovers?

Freezing isn't recommended as potatoes become watery and grainy when thawed. This dish is best enjoyed fresh or refrigerated for up to 3 days.
