Recipe Information
Ingredients
- 2 large Onions
- 2 bulbs Garlic
Instructions
Preheat your oven to 150°F (65°C). If your oven doesn’t go that low, set it to the lowest temperature and optionally crack the door slightly to maintain a lower heat.
Peel the onions and cut them into very thin slices, aiming for uniform thickness to ensure even drying. Use a mandoline slicer if you have one for consistent results.
Peel the garlic cloves and slice them finely as you did with the onions. Again, use a mandoline slicer if available.
Line baking sheets with parchment paper to prevent sticking. Arrange the sliced onions on one baking sheet and the sliced garlic on another, ensuring the pieces are spread out evenly in a single layer with no overlap.
Place the baking sheets in the oven. If you are using multiple sheets, rotate them occasionally to ensure even drying.
Let the onions and garlic dry in the oven for 2.5 to 3 hours, or until they are completely dehydrated and brittle to the touch. Check periodically to avoid burning, especially toward the end of the drying time.
Once dried, allow the onion and garlic flakes to cool completely before handling.
Transfer the dried onion and garlic flakes into airtight containers or glass jars. Store them in a cool, dark place for up to 6 months.
Optional: For a finer texture, you can pulse the dried onion or garlic in a food processor or spice grinder to create onion or garlic powder.
