Garlic Powder vs. Garlic Salt: Sodium

Garlic powder is dried, ground garlic. Garlic salt is salt with some of that garlic blended in, and it is mostly salt: McCormick’s garlic salt carries 540 mg of sodium per ¼ teaspoon,¹ close to the 590 mg in the same measure of Morton’s iodized table salt.² Plain garlic powder has almost none.³ So garlic powder seasons a dish with garlic, and garlic salt seasons it with salt that tastes of garlic. Measure each accordingly.

Side by side

	Garlic powder	Garlic salt
What it is	Garlic cloves, usually sliced, dried at low temperature and ground⁴	Salt blended with dried garlic, usually with an anticaking agent; some brands add starch, sugar or parsley¹⁵
Plant	Garlic, Allium sativum⁶	Same garlic, as a minor ingredient¹
Salt to garlic	None added	No label states it. ATK says commercial garlic salt is typically 3 parts salt to 1 part garlic powder;⁷ UC ANR’s home recipe is 4 to 1⁸
Sodium, per ¼ teaspoon	About 0.5 mg (USDA generic garlic powder; our arithmetic)³	McCormick 540 mg;¹ Lawry’s with Parsley 350 mg⁵
For comparison		Morton iodized table salt, 590 mg per ¼ teaspoon²
One teaspoon weighs	3.1 g (USDA)³	No published figure found
Equal to one clove	1/8 to 1/4 teaspoon; sources disagree (table below)	¾ teaspoon per medium clove (NDSU)⁹
Flavor (editorial)	Garlic only, rounder and sweeter than fresh	Salt first, garlic second
Typical uses	Rubs, blends, dressings, sauces, anywhere you want garlic without changing the salt	In place of some or all of a recipe’s salt: McCormick suggests burgers, chili, tacos and meatloaf¹
Price	No dated, sourced comparison found	No dated, sourced comparison found

The sodium figures belong to different scopes. The garlic powder figure is USDA’s generic analysis: 60 mg of sodium per 100 g and 3.1 g per teaspoon,³ which by our arithmetic is about 2 mg per teaspoon. The garlic salt figures come from two brands’ Nutrition Facts labels, and the two brands differ by about 54 percent.¹⁵ Check your own jar.

The real difference: salt

Everything else follows from how much salt is in the jar. Table salt is about 40% sodium,¹⁰ and garlic salt is three or four parts salt to one of garlic, depending on whose figure you use.⁷⁸ One teaspoon of McCormick’s garlic salt carries about 2,160 mg of sodium by our arithmetic from the label,¹ more than the World Health Organization’s recommended adult limit of less than 2,000 mg of sodium a day.¹¹

Two practical consequences, both our judgment:

You can’t add garlic without adding salt. If a dish needs more garlic flavor, more garlic salt also means more salt. Garlic powder lets you set the two separately.
Garlic salt replaces salt, not garlic. Use it where a recipe calls for salt, and cut the plain salt to match.

America’s Test Kitchen tested dried garlic products against fresh garlic in a Caesar salad and garlic bread. Its tasters gave garlic salt exceptionally low scores, objecting to a “chemical,” “super-salty” taste, and ATK’s advice is that in a pinch any dried garlic product except garlic salt will do where garlic is a background flavor.⁷

Flavor and how to get more of it

Garlic powder holds alliin and the enzyme alliinase, which react to make allicin, garlic’s main flavor compound, once the powder is wet.¹² Heat can inactivate the enzyme.⁴ ATK found that powder straight from the jar has not developed its full flavor, and recommends stirring it into an equal amount of water before use.¹² In its experiment, powder sautéed in butter before it met any moisture ended up with almost no garlic flavor at all.¹³

Garlic salt carries the same kind of dried garlic,¹ so the same logic should apply, but we found no test of hydrating garlic salt. Treat that as untested.

Can one stand in for the other?

Yes, as long as you account for the salt. The ratio labels below follow the site’s four treatments: Computed (a measurable basis), Attributed (a named source’s figure), Disputed (sources disagree) and Method (no published number; a starting point).

Garlic powder in place of garlic salt

Part of the swap	Per 1 teaspoon garlic salt	Treatment
Salt	About 7/8 teaspoon table salt to replace McCormick’s; about 5/8 teaspoon to replace Lawry’s	Computed from sodium labels¹⁵²
Garlic	A scant ¼ teaspoon garlic powder	Attributed: 3:1 (ATK) puts ¼ teaspoon of powder in each teaspoon; 4:1 (UC ANR) puts 1/5 teaspoon⁷⁸

The salt figures match sodium, not flavor, and hold only for those labels: McCormick’s 540 mg and Lawry’s 350 mg per ¼ teaspoon against Morton’s 590 mg.¹⁵² The garlic figure is our arithmetic from each source’s ratio. More options are on garlic salt substitutes.

To keep a jar on hand, UC Agriculture and Natural Resources gives a home recipe: 4 parts salt to 1 part garlic powder, blended for 1 to 2 seconds, packed in an airtight container.⁸

Garlic salt in place of garlic powder

Salt (Computed): By volume, McCormick’s garlic salt carries about 92 percent of the sodium of Morton’s table salt.¹² Replace up to the same volume of the recipe’s salt with garlic salt.

Garlic (Method): No source gives a garlic-salt-for-garlic-powder ratio. To match the garlic in a recipe’s powder you would need three or four times as much garlic salt, with far more salt than most dishes can take. Let the recipe’s salt set the amount and accept a milder garlic flavor. See garlic powder substitutes.

Against fresh garlic

Both are often measured against a clove. Published powder-to-clove figures disagree:

Source	Garlic powder	Fresh garlic
NDSU Extension, FN198⁹	1/8 tsp	1 small clove
NMSU Extension, E-131¹⁴	1/8 tsp	1 small clove
McCormick organic garlic powder page, product details¹⁵	1/4 tsp	1 clove
McCormick organic garlic powder page, image tip¹⁵	1/8 tsp	1 clove

These are round-number kitchen rules, not measurements, and they don’t agree on clove size. ATK also gives 1/4 teaspoon per clove.⁷ A reasonable starting point is 1/8 teaspoon per clove, then taste. For garlic salt, NDSU gives ¾ teaspoon for one medium clove;⁹ if you swap that for fresh garlic, add plain salt back. For more, see garlic powder vs. garlic.

Which to use where

These are kitchen judgments rather than sourced rules:

Garlic powder for spice rubs and blends where you set the salt separately, for dressings and sauces (hydrate it first¹²), and for any dish that is already salty, such as one with soy sauce, cheese or cured meat.
Garlic salt as the salt in a simple dish: garlic bread, popcorn, fries, roasted potatoes, or the burgers, chili, tacos and meatloaf McCormick suggests.¹
Neither in a hot, dry pan. Powder heated before it meets moisture loses most of its flavor.¹³ Add it with liquid or after the aromatics.

Health: it’s the sodium

WHO names raised blood pressure as the primary health effect of diets high in sodium, and its fact sheet lists cardiovascular diseases, gastric cancer, obesity, osteoporosis, Ménière’s disease and kidney disease among the associated risks.¹¹ Its recommendation for adults is less than 2,000 mg of sodium a day, equivalent to less than 5 g of salt.¹¹ Plain garlic powder contributes almost no sodium;³ garlic salt contributes nearly as much as table salt.¹² If you’re watching sodium, garlic powder plus a measured amount of salt gives you control that a premixed jar can’t.

Neither form is a meaningful source of nutrients at seasoning amounts. Garlic’s health research mostly concerns supplements, not seasonings; see garlic powder.

What isn’t known

No commercial garlic salt label states its salt-to-garlic ratio. ATK’s 3:1 and UC ANR’s 4:1 are a test kitchen’s general description and a home recipe.
No source tests whether hydrating garlic salt improves its garlic flavor, as it does for powder.
No published weight per teaspoon for garlic salt was found, so the comparisons on this page are by volume.
No source measures how strong garlic salt’s garlic flavor is against powder or fresh garlic.
