Homemade Garlic Powder from Garlic Peels
Transform your kitchen waste into a flavorful culinary treasure with this simple, sustainable recipe that turns discarded garlic peels into aromatic garlic powder. This zero-waste cooking hack not only reduces food waste but also provides you with a nutrient-rich seasoning that rivals store-bought versions.
Equipment
- 1 Baking Sheet A flat sheet with raised edges works best
- 1 Parchment paper Optional but helps with cleanup
- 1 Food processor or spice grinder For grinding dried peels into powder
- 1 Fine mesh sieve For sifting the final powder
- 1 Airtight container For storing the finished garlic powder
- 1 Spatula For spreading and collecting dried peels
Ingredients
- 3 cups garlic peels Collected from approximately 15-20 garlic bulbs
- ¼ tsp Salt Optional - helps with preservation and enhances flavor
Instructions
Collection & Preparation
- Collect garlic peels from 15-20 bulbs over time
- Store peels in an airtight container in the freezer until ready to use
- Preheat oven to lowest setting (150-170°F / 65-77°C)
- Line a baking sheet with parchment paper
- Spread peels in a single layer without overlapping
Drying Process
- Place baking sheet in preheated oven for 1-2 hours
- Check every 20-30 minutes and stir for even drying
- Test for doneness – peels should be brittle and crumble easily
- Remove from oven when completely crisp
- Let cool at room temperature for 30 minutes
Grinding & Finishing
- Transfer cooled peels to food processor or spice grinder
- Pulse several times, then process continuously for 1-2 minutes
- Add 1/4 teaspoon salt if desired (optional)
- Sift through fine mesh sieve for uniform texture
- Re-grind larger pieces or save as garlic flakes
- Store in airtight glass container
- Label with preparation date
Notes
-
Collection Method: The most efficient way to collect garlic peels is to keep a small container in your freezer and add to it each time you use fresh garlic. Freezing helps preserve the peels until you have enough for a batch.
-
Oven Alternative: If you own a food dehydrator, it works exceptionally well for this recipe. Set it to 125°F (52°C) and dry for approximately 1-2 hours, or until completely brittle.
-
Color Indicator: The color of your final garlic powder may vary from off-white to light tan. This is normal and depends on the age and variety of garlic used. A slightly darker color often indicates a more intense flavor.
-
Flavor Boost: For a more complex flavor profile, you can add a small amount of dried garlic flesh (the papery thin layers between cloves) to the peels before drying. This increases the allicin content and intensifies the garlic flavor.
-
Texture Control: The fineness of your powder depends on how long you process it. For a coarser "garlic granules" texture, pulse less. For ultra-fine powder, increase processing time and sift multiple times.
-
Moisture Test: Before storing, test for complete dryness by placing some powder in a sealed container for a few hours. If condensation appears on the inside, the powder needs additional drying time to prevent mold during storage.
-
Flavor Preservation: Store away from direct sunlight and heat sources to maintain potency. The volatile compounds in garlic that give it its distinctive aroma and flavor can degrade with exposure to light and heat.
