How to Make Homemade Dried Turmeric Powder

Of all the things we grow and dehydrate, homemade turmeric powder is among the most unique – and one of the most healthy! Curcumin, the active ingredient in turmeric, is arguably one of the most beneficial and healing herb compounds in existence. Not to mention, turmeric powder is really tasty! While it is commonly used in curry powder, turmeric powder itself is not spicy. Rather, it has an earthy, slightly bitter, and mildly sweet flavor. Fresh homemade turmeric powder has the best flavor of them all.

Read along to learn how to make turmeric powder at home. The process is quite easy, and very rewarding! To make homemade turmeric powder, all you need is a decent helping of fresh turmeric rhizomes, a food dehydrator, and a blender or food processor. An oven can also be used to dry the turmeric in a pinch, if a dehydrator is not available.

To make turmeric powder, you can use store-bought or farmers market rhizomes. I suggest sourcing organic turmeric rhizomes if possible. However, the most cost-effective way to create a substantial supply of turmeric powder is to grow and dry your own turmeric! Learn how to grow turmeric in any climate here. With our homegrown turmeric, we have enough to enjoy some rhizomes fresh, freeze a few, keep some as seed to re-plant, and make turmeric powder from the rest.

Health Benefits of Turmeric Powder

Curcumin is known to have very strong anti-inflammatory and antioxidant properties. In fact, thousands of scientific studies have shown that curcumin is effective at reducing inflammation, improving memory, preventing and slowing cancer development, boosting the immune system, regulating blood pressure, and more. It is truly phenomenal stuff! Curcumin is also what gives turmeric powder its lovely orange pigment.

Because of all this awesomeness, we consume as much turmeric as we can! This includes adding homemade turmeric powder to many meals, as well as taking a whole raw turmeric supplement daily.

However, note that raw curcumin and turmeric isn’t easily absorbed by the body. To get the most benefit from curcumin, it is suggested to consume it with black pepper and/or a healthy fat (such as olive oil, coconut oil, coconut milk). Both of which increase the bioavailability and thus uptake in your body. Prolonged high heat destroys some of the beneficial properties of turmeric, but a small exposure to heat also helps increase turmeric’s solubility and absorption. Therefore, cooking with turmeric powder may be more beneficial than consuming it raw.

We’ll talk more about the ways we use turmeric powder at the end of this article. But now, how to make turmeric powder…

SUPPLIES NEEDED

• Fresh turmeric rhizomes
• A food dehydrator (preferred method)
• Oven (if you don’t have a food dehydrator)
• Vitamix, blender, or food processor for grinding
• Fine-mesh strainer for sifting, optional but recommended

INSTRUCTIONS

Step 1: Wash & Slice Turmeric

Before you get started, wash the turmeric rhizomes. You don’t need to bother peeling off the outer skin though. It will simply get dried, ground, and incorporated into the powder. Next, cut the turmeric into thin slices. The thinner you go, the quicker they will dry. Furthermore, the more consistent the cuts, the more evenly they’ll finish drying together. We typically aim for about 1/8” to 1/4″ thick, if I had to measure – which I don’t!

Fair warning: turmeric can stain your equipment, including the cutting boards, blender, and your fingers.  

Lay the slices of turmeric out evenly on your food dehydrator trays as you go. You can pack a large amount on to each tray! The pieces can touch side to side, but make sure they aren’t piled on top of each other. We want space for good air flow between them. 

Do you need to boil turmeric before dehydrating it?

If you have done any research into how to make turmeric powder, you may have noticed some conflicting information about whether or not you should boil the turmeric before dehydrating it. Some instructions suggest this helps to soften the rhizomes for preparation and reduce drying time. Others give no reason for the additional step.

We have made turmeric powder both ways in the past – boiled before drying, and not. Truth be told, I do not see the need to boil it first – and we no longer do when we make turmeric powder. The turmeric dries just as well without boiling. Plus, I worry that valuable nutrients are lost in the water or destroyed by heat during the boiling process!

Step 2: Dehydrate the Turmeric

Load your food dehydrator with the trays of sliced turmeric. To retain as much nutritional value as possible, we choose to dry ours on about 100-110°F – which is considered the “raw foods” setting on our dehydrator. If you aren’t overly concerned about that, you can use a warmer setting (around 130°F) and it will dry a bit faster.

The time it takes to fully dry will vary. It depends on your dehydrator or oven, how you prepared and organized the turmeric, and the temperature you use. When we used our old Nesco dehydrator, it took several days on a low setting to completely dry. Our Excalibur dries it nicely in about half that time, and could easily do it in less than 12 hours on a higher temperature setting than we choose to use.

Drying Turmeric in the Oven:

If you want to use the oven, prepare your turmeric in a the same fashion as described above. Next, spread them in a thin layer on a baking pan covered with parchment paper. Bake the turmeric on the lowest heat setting possible until they are completely crunchy dry. It is suggested to stir and re-spread the turmeric bits every hour as you go to promote even drying. We have never done this, but read that this method takes most of the day.

Step 3: Check Doneness

Before removing the turmeric from your dehydrator or oven, check to make sure the pieces are completely dry! If you try to break them, the thin dry slices should snap and crack crisply in half, and not bend or be malleable at all. The texture tells you if all the excess moisture has been removed. If they’re still bendy or soft instead of crunchy, keep on drying!

If too much moisture is left, your turmeric powder will clump up later in the storage container!   

Once the turmeric is super dry, it’s….

Step 4: Grind the Turmeric Powder

Next, it is time to grind your crispy dry turmeric bits into a fine powder. This can be done in a blender, food processor, or coffee grinder. Simply pulse and grind it until all the chunks appear to be broken up. In a Vitamix, the result is a super fine, fluffy powder.

Helpful tip:

Even using a Vitamix, I find that some larger hard bits are left behind after the initial blend. Therefore, I like to pour the ground turmeric powder through a fine mesh strainer poised over a bowl and sift it. Then, I take the collected leftover hard bits and run them back through the Vitamix another time to pulverize them into powder. Repeat if necessary. Then use a rubber scraper to gather all of the homemade turmeric powder stuck inside your blender or machine. That is valuable stuff!

Step 5: Store, Use & Enjoy! 

Store the finished homemade turmeric powder in an air-tight glass container, such as in a mason jar with tight-fitting lid. A canning funnel really comes in handy to transfer the power into a jar without spilling. Keep the container in a dry, cool place. We store ours in the pantry. When properly dried and stored, your homemade turmeric powder should last for over a year. That is, if you don’t use it all up before then!

Use your turmeric powder the same way you may use curry powder, and beyond! We like to sprinkle homegrown turmeric powder over garden veggies as they sauté in our favorite cast iron wok, add it to soups like this roasted carrot and sweet potato soup, or along with with rice, beans or lentils – such as our madras curry lentils recipe.

We even like to mix turmeric powder into our homemade sourdough bread sometimes! Furthermore, turmeric powder can be used to make golden milk – a slightly sweet and very healthy beverage. I will share our golden milk recipe very soon, and link it here.
