Short answer

Add garlic after the onions, not with them, and cook it for thirty to sixty seconds only. Garlic has very little water and a lot of sugar, so it goes from fragrant to bitter in seconds — if it has browned past golden, start again.

Onions take eight minutes to soften. Garlic takes under a minute. Adding them at the same time is the single most common reason a dish has a harsh, bitter background note, and once garlic is burnt there is no way to season around it.

What you'll need

Pan
Sharp knife (optional)

Step by step

Cook onions and other slow aromatics first.Give them their full eight to ten minutes over medium heat before garlic goes anywhere near the pan.
Add garlic for the last 30-60 seconds only.You are cooking it until fragrant, not until coloured. Pale gold at most.
Turn the heat down before it goes in.Medium-low. Garlic burns at temperatures that onions handle comfortably.
Stir constantly once it is in.A minute of attention. Garlic sitting still against hot metal burns in patches while the rest is raw.
Add the liquid or next ingredient promptly.Tomatoes, stock, wine — anything wet drops the temperature and takes garlic out of the danger zone.
Cut it larger if the dish cooks for a long time.Whole or halved cloves survive a long braise. Finely minced garlic disintegrates and can turn acrid.
If it has burnt, start the aromatics again.Burnt garlic is genuinely bitter and it will run through the entire dish. Wipe the pan and spend two minutes redoing it.

Tips

Sliced garlic is more forgiving than crushed or minced — less surface area means slower browning.
For garlic-forward dishes, adding half early and half at the very end gives depth plus freshness.
Garlic in oil over low heat for several minutes — properly gentle confit-style cooking — is sweet and mellow. It is speed and high heat that produce bitterness.

Common mistakes

Adding garlic and onions to the pan together — By the time onions are soft the garlic has been burning for seven minutes.
Trying to cook around burnt garlic — Bitterness from burnt garlic cannot be masked with salt, sugar or acid. Restarting the aromatics is faster than trying.
Walking away for 'just a second' — Garlic goes from golden to black in roughly fifteen seconds at frying temperature.

Questions people ask

When should I add garlic when cooking?

Near the end of the aromatic stage — after onions have softened, about thirty to sixty seconds before you add liquid. It only needs to become fragrant.

Can you save a dish with burnt garlic in it?

Rarely. The bitterness spreads through everything. It is quicker to wipe the pan out and redo the aromatics than to try to season around it.
