Question: can you freeze onions and garlic?
Answer: To freeze, peel the onions and garlic and slice and dice (or, for garlic, mince) to your heart's content. ... Portion out the chopped onions and garlic in ice cube trays or on a baking sheet lined with parchment and coat them with oil. Stick them in the freezer for at least 3 hours, then transfer to containers for storage.
