Comment faire revenir les oignons jusqu'à tendreté
Réponse courte
Cut the onion into thin, even wedges. Cook in 1 tbsp fat over medium-low heat for 8–12 minutes, stirring regularly, until soft and translucent — not browned.
Valable quand
- The onion is cut into even wedges about 3–4 mm thick.
- One large onion is cooked in a 24–28 cm pan without a deep, crowded layer.
- Medium-low heat means gentle cooking with no smoke or hard browning.

Ce qu'il te faut
- 1 large onion
- 1 tbsp oil or butter
- 24–28 cm frying pan
- Sharp knife and cutting board
- Wooden spoon or spatula
Étape par étape
1
Halve and peel the onion. Cut from root to tip into even wedges about 3–4 mm thick.
- Matériel: Sharp knife and cutting board.
- Chaleur: No heat.
- Temps: 2–3 minutes.
- Aspect: The wedges are roughly the same thickness.
- Si ça tourne mal: Very uneven thickness — split the thickest wedges so they cook at the same rate.
- Prêt quand: The onion is ready in thin, even wedges.
2
Heat 1 tbsp oil or butter in the pan and spread the fat across the base.
- Matériel: 24–28 cm frying pan.
- Chaleur: Medium-low heat.
- Temps: 30–60 seconds.
- Aspect: Oil flows easily or butter foams gently; the fat is not smoking.
- Si ça tourne mal: Smoke or dark butter — remove the pan, wipe it out and restart over lower heat.
- Prêt quand: The fat is hot and evenly spread without smoking.
3
Add the onions, spread them in an even layer and stir every 1–2 minutes.
- Matériel: Wooden spoon or spatula.
- Chaleur: Medium-low heat throughout.
- Temps: 8–12 minutes.
- Aspect: After about 4 minutes the onions collapse; at 8–12 minutes they are soft and translucent without browning.
- Si ça tourne mal: Edges brown too quickly — lower the heat, add 1 tbsp water and loosen the darkening spots.
- Prêt quand: No raw, crunchy center; the onions are soft and translucent.
4
Remove the soft onions from the heat. Continue only if you intentionally want light, even browning.
- Matériel: Spatula and serving bowl.
- Chaleur: Off for soft onions; medium for intentional light browning.
- Temps: Immediately, or 2–4 extra minutes for light browning.
- Aspect: Soft onions are evenly translucent; browned onions are golden across the surface, not black at the edges.
- Si ça tourne mal: Black edges and a bitter smell — remove the burnt pieces; they cannot be softened away.
- Prêt quand: The chosen result is reached without burnt pieces.
Si ce n'est pas comme prévu
Burnt edges while the center is raw
lower the heat and cut the onion more evenly next time.
Onions simmer in liquid
use a larger pan and keep them in one even layer.
Onions dry out
add a small amount of fat or 1 tbsp water and lower the heat.
Still not soft after 12 minutes
cover for 1–2 minutes over low heat, then check again.
Sécurité alimentaire
Lower the onions into the fat close to la poêle to avoid splashes of hot fat.
C'est prêt quand: The onions are soft and translucent, with no raw, crunchy center or dark edges.
