Nearly every recipe opens with the same line: "Chop and fry the onion." In practice, that simple sentence means tears, a smelly cutting board and knife, and ten minutes at the stove. Now imagine cutting out most of that work with one spoonful from a jar — without sacrificing the dish's flavor. That is exactly what dried onion and garlic do, and it's why they hold a permanent place in commercial and restaurant kitchens.
Of course, "dried" doesn't mean "replaces fresh always and everywhere"; each form has its own place. In this article from the Narmila journal, you'll learn how the different types of dried onion and garlic (flakes, granules, powder) compare, what the substitution ratios for fresh are, which dishes they shine in, and where you're better off skipping them. You'll find these products in Narmila's cooking products range.
Flakes, granules or powder? Three forms, three jobs
Dried onion and garlic come in three main forms, and choosing well between them is half the skill:
Flakes (dried slices): visible pieces of onion or garlic. They soften in the dish and take on a texture close to cooked onion. The best choice for soups, braises, stews and anywhere you have liquid and enough cooking time. Onion flakes are also excellent on burgers and salads (after a brief soak).
Granules (fine grains): the middle ground between flakes and powder — a coarse grind. They open up faster than flakes and, unlike powder, don't clump. For marinades, sauces and spice blends, they're the most balanced option. If you're only going to buy one form, granules are the all-rounder.
Powder: a complete grind, with maximum surface area and the fastest flavor release. Use it for direct seasoning (potatoes, chicken, popcorn), cold sauces and anywhere you want zero texture. Its weak point is moisture absorption and clumping, so take the lid seriously.
A handy rule of thumb: the shorter the cooking time, the finer the form. A stew simmering for hours is happy with flakes; a two-minute omelet only works with powder or granules.
Substitution ratios for fresh onion and garlic
The amounts below are a reliable starting point for substitution:
| Instead of... | Flakes | Granules | Powder |
|---|---|---|---|
| 1 medium onion | 3 tbsp | 1 tbsp | 1 heaping tsp |
| 1 clove of garlic | 1 tsp | 1/2 tsp | 1/4 tsp |
tbsp = tablespoon | tsp = teaspoon
A few notes that make this table more precise:
- Dried is more concentrated than fresh. Once the water is removed, the flavor compounds are compressed, which is why dried amounts are always several times smaller than fresh. When in doubt, use less — the flavor of dried onion and garlic "opens up" during cooking and comes across stronger.
- Garlic powder has less "bite" than fresh garlic, but more depth. The sharp, pungent heat of fresh garlic mellows during drying, and what remains is a rounded, cooked-tasting flavor. For people who find fresh garlic heavy, that's actually an advantage.
- Don't scale linearly in big-batch recipes. For a large pot that calls for 4 onions, don't start with 10 tablespoons of flakes; start with 7 to 8 and taste after half an hour.
Where they shine, use by use
Soups and ash (hearty Iranian soups): dried onion's home turf. Add onion flakes right at the start with the legumes or soup base; they soften completely during cooking and lend the whole dish a gentle sweetness that beats half-cooked fresh onion. Add dried garlic in the second half of cooking.
Stews and braises. On days when there's no time for piaz dagh (Persian fried onions), onion flakes plus a little turmeric, sauteed briefly and gently in oil, build a perfectly respectable base. It won't recreate true fried onions one hundred percent, but the gap is far smaller than you'd think — especially in heavily spiced stews like gheymeh (Iran's split-pea and meat stew).
Marinades for chicken, meat and kebabs. Here granules and powder are king: they blend smoothly into yogurt, tomato paste or oil and, unlike grated onion, don't release water and thin out the marinade. Garlic powder + onion powder + paprika + salt = a universal marinade base.
Direct seasoning. Powder over baked potatoes, Mexican street corn, popcorn, homemade garlic bread (garlic powder + butter + dried parsley on toast), and even yogurt and borani dips. Put this use alongside tomato powder and you have a complete seasoning shelf.
Cold sauces and dips. Dried garlic in yogurt, mayonnaise or homemade ranch spreads an even aroma without the sharp heat of fresh garlic. Let the sauce rest for ten minutes so the granules open up fully.
Where to skip them: an honest look at the limits
No ingredient does everything; knowing the limits matters as much as knowing the uses:
- Generous, caramelized fried onions: for dishes built on heaps of golden fried onion (adas polo, festive tahchin, halim bademjan), fresh onion has no full substitute. Dried onion can't produce the caramel sweetness that comes from long frying.
- Raw onion for salads and sandwiches: the crisp, juicy bite of raw onion belongs to fresh onion. Soaked flakes are an "acceptable" stand-in, not an equal.
- Fragrant sauteed garlic for pasta: the aroma of fresh garlic blooming in olive oil is the signature of certain dishes; garlic powder plays the same role with a different personality.
A fair summary: in liquid-based dishes, marinades and seasoning, dried onion and garlic are the equal of fresh — sometimes better. In "texture-first" and "long-fry" roles, they're a complement, not a replacement. A smart cook keeps both in the kitchen and picks the right form for each dish.

The common complaint "my dish turned bitter with dried onion" almost always has one of three roots:
Mistake 1: sauteing in hot oil. Dried onion and garlic have no protective moisture, and in hot oil they go from golden to burnt in seconds — and burnt garlic means absolute bitterness. If you want to saute: gentle heat, oil that isn't too hot, and one minute at most. Or, safer still: add a splash of water to the pan first, then the flakes, so they soften in the steam.
Mistake 2: using too much. "One more spoonful for extra aroma"? No. The concentrated sulfur compounds in dried onion and garlic turn bitter and astringent at high doses. Stay faithful to the ratio table and let the cooking time do its work.
Mistake 3: adding them late to a dish with little liquid. Flakes added in the last five minutes to a thick braise never get the chance to soften, and they come through as tough, half-bitter bits. Flakes need time and liquid; if both are short, use powder or granules instead.
Homemade spice blends with dried onion and garlic
The most professional way to use these two is to build ready-made blends. Here are three base recipes, each with dozens of uses (ratios are in "parts", using any measure you like):
All-purpose potato and chicken seasoning: 2 parts onion powder + 1 part garlic powder + 2 parts paprika + 1 part salt + 1/2 part black pepper. For baked potatoes, chicken wings and corn.
Instant soup base: 3 parts onion flakes + 1 part garlic granules + 2 parts dried parsley + 1 part dried cilantro. Two spoonfuls of this blend + boiling water + vermicelli or rolled barley = a ten-minute soup. For more on the dried herbs in this mix, see our article on cooking with dried herbs.
Bread and cheese topping (bagel-style): 2 parts onion flakes + 1 part garlic flakes + 2 parts sesame seeds + 1 part poppy seeds + a little sea salt. Sprinkle over homemade bread before baking, or onto cream cheese.
Keep each blend in a small, sealed, labeled jar. Three little jars turn your everyday cooking from "starting from scratch every time" into "one spoonful and done."
Storage: the eternal enemies of dried goods
The storage rules for dried onion and garlic are the same four golden rules for all dried goods: a sealed container, away from moisture, away from light, away from heat. A few specifics:
- They give off odors — and pick them up too: keep dried onion and garlic in a glass jar with a gasket-sealed lid, both so their strong smell doesn't spread to the rest of the cupboard and so they don't absorb moisture. Plastic is not a good choice for these two.
- Powder is more delicate than flakes: garlic powder is the most moisture-hungry member of the family. Always a dry spoon, always a closed lid. A dry clump is harmless; a damp clump with an off smell means it's time to say goodbye.
- Shelf life: flakes keep their full aroma for about a year, granules and powder for 8 to 12 months. After that they don't spoil, but they lose their punch. Simple test: rub a little in your palm; if the aroma is weak, it's time to replace it.
- Away from the stove: the shelf above the stove is the worst home for any spice; heat and steam drive off the aroma months early. Read the full principles of storing dried goods in this guide.
The takeaway: two jars that simplify your cooking
Dried onion and garlic are a shortcut in the truest sense: the same familiar flavor base, without the tears, the smell or the wasted time — as long as you follow three rules: the right form for the right dish (flakes for long cooking, powder and granules for quick jobs), a more concentrated ratio than fresh, and never hot oil. With those three rules and two or three homemade blends on hand, the pace of your everyday cooking picks up noticeably.

Frequently asked questions
How much fresh onion does a spoonful of dried onion replace?
Three tablespoons of onion flakes, one tablespoon of granules, or one heaping teaspoon of onion powder each roughly equal one medium fresh onion. Since the dried flavor is more concentrated, it's best to start with slightly less.
Is garlic powder better than fresh garlic?
Each has its place. Fresh garlic has sharp heat and aroma and is unbeatable sauteed in oil (as in pasta). Garlic powder is milder and more even, and it's the better choice for marinades, cold sauces, direct seasoning and liquid-rich dishes.
Why does dried onion turn bitter in food?
There are three common causes: sauteing in hot oil (which burns it within seconds), using too much, and adding it late to a dish with little liquid, giving it no chance to soften. With gentle heat, the right ratio and enough time, no bitterness develops.
Can you make fried onions (piaz dagh) with dried onion?
Rich, caramelized fried onions are the domain of fresh onions, and the dried version can't fully recreate them. But as a stew base on busy days, a very brief, gentle saute of onion flakes with a little turmeric is a perfectly acceptable stand-in.
How should dried onion and garlic be stored?
In a tightly sealed glass container, away from light, heat and moisture — and preferably not in the shelf above the stove. Flakes keep their full aroma for about a year, powder and granules for 8 to 12 months, provided you always use a dry spoon.
Do onion flakes need soaking before use?
Not in liquid-rich, slow-cooked dishes; the food softens them on its own. For rawer uses such as salads, burgers or dishes with little liquid, ten minutes of soaking in lukewarm water softens the texture and mellows the flavor.
Two small jars of dried onion and garlic are the kind of tiny investment that pays you back every single day. Read more seasoning and cooking guides in the Narmila journal, and ask your questions through our contact page.
