How Do You Heat Up Costco Tamales?
To heat up Costco tamales, place them in a microwave-safe dish and cover them with a damp paper towel. Microwave them on high for 1-2 minutes per tamale or until heated through. Alternatively, you can steam the tamales by wrapping them in damp paper towels and placing them in a steamer basket over boiling water for 15-20 minutes.
