Equipment and Ingredients You’ll Need
- 6 heads of garlic (or more, depending on how much powder you want)
- Food dehydrator, Air Fryer with Dehydrator, or traditional oven
- Spice grinder/coffee grinder, or food processor
- Baking sheet lined with parchment paper
- Airtight container for storage
Step-by-Step Guide to Homemade Garlic Powder:
Step 1: Preparing the Garlic
The first step in making garlic powder is selecting fresh, high-quality garlic heads. For the best results, I recommend using firm, unblemished garlic cloves.
Start by separating the cloves from each garlic head. This can be done by pressing down on the garlic head gently to loosen the cloves. Next, peel each garlic clove. You can speed up this process by placing the cloves in a jar, shaking them vigorously to loosen the peels, or using the flat side of a chef’s knife to crush the cloves slightly.
Once peeled, it’s time to slice the garlic. Slice each clove as evenly as possible to ensure consistent drying. A garlic slicer works well for this step, but if you’re doing it by hand, aim for slices around 1/8 of an inch thick. Uniformity here is key to avoiding pieces that dry unevenly, which could impact the final product.

Step 2: Drying the Garlic
You have two primary options for drying garlic: using a food dehydrator or your oven. Both methods are effective, but the dehydrator tends to produce more consistent results.
Using a Food Dehydrator or Air Fryer as a Food Dehydrator
- Arrange the garlic slices in a single layer on the dehydrator trays, making sure they don’t overlap.
- Set the dehydrator to 125°F (52°C) for optimal drying. This low temperature preserves the garlic’s natural oils and prevents it from burning.
- Dry for 10-12 hours, checking periodically to ensure even drying. The garlic is ready when it’s brittle and breaks easily when bent.
- Rotate the trays occasionally to promote even airflow and drying.
Using an Oven:
- If you don’t have a dehydrator, your oven works just as well. Preheat it to a low temperature of 150°F-200°F (67°C-93°C).
- Spread the garlic slices in a single layer on a parchment-lined baking sheet.
- Bake the garlic slices for 1-2 hours, flipping halfway through to ensure even drying. You’ll know the garlic is done when the slices are crisp and snap easily.
- Be sure to keep an eye on the garlic to prevent it from burning, especially if your oven runs hot.
Pro Tip: Whether using a dehydrator or an oven, good ventilation is key. Dehydrating garlic produces a strong smell, so consider placing your equipment in a well-ventilated area or even outdoors if possible.
This will help dissipate the odor and ensure that the garlic dries evenly.

Step 3: Grinding the Dried Garlic
Once the garlic is fully dried, allow it to cool completely before grinding. This ensures that no residual moisture remains, which could cause clumping during storage.
Grind the garlic using an electric coffee grinder, spice grinder, or food processor. Start by pulsing the grinder in short bursts to break down the garlic slices into smaller pieces. Then grind them into a fine powder, stopping periodically to check the texture.
If you want a super-fine texture, sift the powder through a fine-mesh strainer to remove any larger bits. These larger pieces can be saved and added to soups, stews, or used as garlic flakes.
Pro Tip: For added flavor variety, you can experiment with roasting the garlic before drying. Roasting will give the garlic powder a deeper, sweeter taste, ideal for adding richness to certain dishes like pasta sauces and roasted meats.

Step 4: Storing Your Homemade Garlic Powder
Proper storage is key to preserving the potency and freshness of your homemade garlic powder. Once the garlic is ground, transfer the powder to an airtight container. Store it in a cool, dry place, away from direct sunlight. Exposure to light and moisture can degrade the flavor over time.
To prevent the powder from clumping, consider adding a teaspoon of uncooked rice or a silica gel packet to the container. These will absorb any moisture and keep your garlic powder free-flowing.
Shelf Life: When stored properly, homemade garlic powder can stay fresh for up to 12 months. For best results, label your container with the date you made it, and remember to check for any signs of moisture or clumping over time.
To create the best homemade garlic powder with maximum flavor and freshness, there are a few important tips to keep in mind throughout the process. These simple but effective techniques will ensure that your garlic powder turns out perfectly every time, with optimal taste and texture. Here are some essential tips to follow:

Use Low, Slow Heat for Drying
One of the most crucial aspects of making dried garlic into powder is using a low temperature during the drying process. Whether you’re using a dehydrator or an oven, keeping the temperature low allows the garlic to dry slowly and evenly, which helps preserve its natural oils and rich flavor.
If dried too quickly or at too high a heat, garlic can develop a bitter taste or lose much of its robust aroma. A slow, gentle drying process prevents this, ensuring that the garlic retains its delicious flavor profile without being overcooked or scorched.
Cut the Garlic into Uniform Slices
To achieve even drying, it’s important to slice the garlic cloves as uniformly as possible. When garlic pieces are cut to a similar thickness, they will dry at the same rate, avoiding issues where some pieces remain too moist while others become overly dry or burnt.
You can use a garlic slicer for consistency or carefully slice by hand, aiming for thin, even slices.
This step is key for ensuring that your garlic dries evenly, which will lead to a better, smoother powder once it’s ground.
Maintain Good Airflow During Drying
Drying garlic can result in a strong odor, especially if you’re dehydrating multiple cloves at once. For this reason, it’s a good idea to make sure you have proper ventilation in your kitchen or dehydrating area. If possible, place the dehydrator or oven in a well-ventilated space, such as near a window, or consider drying garlic outdoors if the weather allows.
Good airflow will not only minimize strong odors but will also help the garlic dry more efficiently. Proper ventilation also reduces the risk of moisture buildup during the drying process, which can affect the quality of the final product.
By following these tips, you’ll ensure that your homemade garlic powder turns out flavorful, evenly dried, and ready to use in your favorite recipes. Whether you’re adding it to spice blends, sauces, or marinades, these small adjustments can make a big difference in the quality of your final product.

Uses for Homemade Spices
- Seasoning blends: Add to homemade spice mixes, rubs, and marinades for an extra kick of flavor.
- Flavor booster: Sprinkle it on meats, vegetables, pasta, or a homemade deep dish pizza for a quick garlic flavor without chopping.
- Dissolving in liquids: Use homemade spices in soups, sauces, and dressings to add flavor without the texture of fresh garlic.
