Comment rôtir les légumes

Réponse courte

Use high heat, even pieces, a thin coat of oil and space on the tray. Combine vegetables with similar cooking times.

Valable quand

  • The portion is 200–250 g vegetables per person.
  • The oven is fully preheated to 220°C conventional or 200°C fan/convection.
  • Vegetables with similar cooking times are cut into even pieces.
  • Everything sits in one airy layer; a pile steams instead of browning.

Ce qu'il te faut

  • 400–500 g vegetables for 2 people
  • 1–2 tbsp oil
  • Salt
  • Large roasting tray
  • Sharp knife and cutting board
  • Spatula or tongs

Étape par étape

  1. 1

    Cut firm vegetables smaller than soft ones and dry the surfaces.

    • Matériel: Sharp knife and cutting board + Spatula or tongs.
    • Chaleur: No heat during preparation.
    • Temps: 2–5 minutes.
    • Aspect: Dry pieces with similar cooking times are grouped together.
    • Si ça tourne mal: Large firm and small soft pieces on one tray cook unevenly.
    • Prêt quand: Dry pieces with similar cooking times are grouped together.
  2. 2

    Coat with oil and salt and spread in one layer with visible gaps.

    • Matériel: Large roasting tray.
    • Chaleur: The stated working heat.
    • Temps: 5–40 minutes depending on ingredient and method.
    • Aspect: Every surface is lightly oiled; nothing sits in a wet pile.
    • Si ça tourne mal: Too much oil makes surfaces greasy; crowding traps steam.
    • Prêt quand: Every surface is lightly oiled; nothing sits in a wet pile.
  3. 3

    Roast undisturbed for the first 12–15 minutes. Turn when the underside has golden patches.

    • Matériel: Large roasting tray + Spatula or tongs.
    • Chaleur: 200–220°C.
    • Temps: 12–15 minutes before turning.
    • Aspect: Every surface is lightly oiled; nothing sits in a wet pile.
    • Si ça tourne mal: Too much oil makes surfaces greasy; crowding traps steam.
    • Prêt quand: Every surface is lightly oiled; nothing sits in a wet pile.
  4. 4

    Roast hot, turn once and remove finished pieces as needed.

    • Matériel: Spatula or tongs.
    • Chaleur: Low heat or off during the final check.
    • Temps: 1–5 minutes.
    • Aspect: Edges are browned and centers are tender with some bite.
    • Si ça tourne mal: Pale surfaces need more heat or space; black tips require an earlier stop.
    • Prêt quand: Edges are browned and centers are tender with some bite.

Si ce n'est pas comme prévu

  • Large firm and small soft pieces on one tray cook unevenly.
  • Too much oil makes surfaces greasy; crowding traps steam.
  • Pale surfaces need more heat or space; black tips require an earlier stop.

Sécurité alimentaire

Use dry maniques, keep your face clear of steam and place hot trays on a heatproof surface.

C'est prêt quand: Edges are browned and centers are tender with some bite.
