Best Fresh Garlic Substitutes (With Ratios)
The best fresh garlic substitute is garlic powder: use 1/8 tsp for each clove called for. For a fresher flavour, stir it into an equal amount of water and let it sit for a few minutes before cooking.
Fresh garlic substitutes
| Substitute | Amount per 1 medium clove (about 1 tsp minced) | Best for | Why it works |
|---|---|---|---|
| Garlic powder | 1/8 tsp | Rubs, sauces, dressings, soups | Dehydrated, finely ground garlic |
| Granulated garlic | 1/4 tsp | Rubs, roasted vegetables, breading | Coarser grind, less likely to clump or burn |
| Jarred minced garlic | 1/2 tsp | Stir-fries, sauces, stews | Real garlic preserved in acid or oil |
| Dried minced garlic or flakes | 1/2 tsp | Soups, stews, slow cooker | Rehydrates in liquid |
| Garlic salt | 1/2 tsp, and reduce other salt by 1/4 tsp | Garlic bread, seasoning, popcorn | Roughly 3 parts salt to 1 part garlic powder |
| Frozen garlic cubes or paste | 1 cube or 1 tsp | Everything cooked | Minced fresh garlic, frozen or tubed |
| Garlic-infused oil | 1 tsp oil | Low-FODMAP cooking, dressings | Fat carries garlic aroma compounds |
| Asafoetida (hing) | Tiny pinch, bloomed in oil | Allium-free curries, dals | Pungent sulfur compounds that taste like garlic and onion when cooked |
| Shallot or chives | 1 tsp minced shallot or 1 tbsp chives | Raw dishes, garnishes | Milder allium flavour |
The science of garlic flavour
A whole garlic clove barely smells. Its flavour is built the instant you cut or crush it. Cells contain alliin (a sulfur-bearing amino acid) and, in separate compartments, the enzyme alliinase. Break the cells and they react, forming allicin, the sharp, hot compound behind raw garlic's bite. Allicin quickly breaks down into other sulfur compounds that give garlic its rich cooked flavour.
The more you damage the cells, the stronger the flavour: a crushed clove or paste tastes more intense than a slice.
Garlic powder is made by drying and grinding garlic. Much of its alliin survives, and some alliinase activity can return when it is rehydrated. That's why a few minutes in water perks up powdered garlic. But dried garlic never quite reaches fresh garlic's sharp, volatile punch.
Cooking tips
- Powder burns fast. Its fine particles scorch in hot oil within seconds, turning bitter. Add it with liquid or near the end, or bloom it in oil over low heat.
- Jarred garlic tastes flatter because acids and heat treatment change its sulfur compounds.
- Fresh garlic browns quickly too. Above about 160 °C / 320 °F it goes from golden to bitter in moments.
Chef Fizz says: Crush, then wait 10 minutes before cooking. That pause gives alliinase time to build more flavour!
When NOT to swap
- Raw garlic dishes: aioli, toum, pesto, tzatziki and gremolata need fresh garlic's bite. Powder tastes dusty raw.
- Roasted whole garlic can't be replaced by powder.
- Don't store homemade garlic in oil at room temperature. Refrigerate it and use within about 4 days, or freeze it.
- Garlic salt in already-salty dishes will overseason; use powder instead.
Questions
How much garlic powder equals one clove of garlic?
About 1/8 tsp garlic powder equals one medium clove (about 1 tsp minced). Use 1/4 tsp granulated garlic, which is coarser and less dense.
How much jarred minced garlic equals a clove?
Use about 1/2 tsp jarred minced garlic per clove. It is milder than fresh because it is stored in acid or oil, so add a little more to taste.
Is there a low-FODMAP substitute for garlic?
Garlic-infused oil works well. The FODMAP fructans in garlic dissolve in water, not fat, so a strained oil carries flavour without them. Asafoetida is another option.
Is it safe to make garlic-in-oil at home?
Only if you refrigerate it and use it within about 4 days, or freeze it. Raw garlic in oil at room temperature can allow Clostridium botulinum to grow.
