Ratatouille Niçoise (Vegan Provençal Vegetable Stew)

Ratatouille Niçoise brings together the defining vegetables of Provençal cooking: aubergine, courgette, peppers, ripe tomatoes, garlic and olive oil, gently cooked into a soft, savoury stew. Rather than a heavy braise, it should feel vegetable-led and summery, with the aubergine browned for depth, the courgette kept tender and the tomatoes forming a loose, glossy sauce. Fresh basil added at the end keeps the flavour bright. Serve it warm as a simple vegan dinner, alongside bread or grains, or as a versatile side for a larger meal.

Why this recipe works

  • Built-in depth: Browning the aubergine before simmering adds savoury depth to an otherwise simple vegetable stew.
  • Fresh but rounded: Ripe tomatoes give the stew acidity and body, while olive oil softens the edges and brings the vegetables together.
  • Good for planning ahead: The flavours settle well after cooking, making this a useful dish to refrigerate, freeze or reheat gently.

Ingredient notes

  • Use ripe tomatoes: Ripe tomatoes give the sauce better sweetness, acidity and body; less ripe tomatoes may need more careful seasoning.
  • Cut evenly: Keeping the aubergine, courgette and pepper pieces a similar size helps them soften at a similar pace.
  • Add basil late: Fresh basil is best stirred in at the end so it keeps its fragrance rather than fading during the simmer.

Texture tips

  • Brown the aubergine properly: Let the aubergine take on deep golden colour before it goes back into the pan; this improves both flavour and texture.
  • Finish uncovered: A short uncovered simmer at the end reduces excess liquid and leaves the vegetables in a richer tomato sauce.

Make-ahead tips

  • Good the next day: Ratatouille keeps well in the fridge, and the flavours often become more integrated after resting overnight.
  • Reheat gently: Warm it in a saucepan over low heat, stirring occasionally, and add a splash of water if the sauce has thickened too much.
  • Freeze in portions: Cool completely before freezing, then defrost overnight in the fridge before reheating until piping hot.

Authenticity notes

  • Niçoise-style vegetable stew: This style of ratatouille reflects Provençal cooking: olive oil, summer vegetables, garlic, tomatoes and fresh herbs cooked into a soft, savoury stew.
  • Colour before simmering: Cooking the vegetables in stages gives them more character than simply simmering everything from raw.

  1. Cut the aubergine and courgette into 2 cm chunks, and cut the red peppers into similar-sized pieces. Finely slice the garlic. Roughly chop the tomatoes and tear most of the basil, reserving a few leaves to finish.
  2. Heat 2 tbsp of the olive oil in a large casserole over medium-high heat. Add the aubergine with a pinch of the salt and cook for 8 to 10 minutes, stirring often, until well browned and starting to soften. Tip into a bowl.
  3. Add the remaining 2 tbsp olive oil to the pan, then add the peppers and cook for 5 minutes until glossy and lightly coloured. Add the courgette and cook for 3 to 4 minutes to take the raw edge off. Stir in the garlic for 30 seconds until fragrant.
  4. Return the aubergine to the pan and add the tomatoes, remaining salt and the black pepper. Bring to a gentle simmer, then cover and cook over low heat for 20 minutes, stirring occasionally, until the vegetables are tender and the sauce is rich. If it looks dry at any point, add a small splash of water and scrape up any browned bits.
  5. Uncover and simmer for 2 to 4 minutes to thicken slightly, then stir through the torn basil. Taste and adjust seasoning with a little more salt and pepper if needed. Serve warm, topped with the reserved basil leaves.

Recipe notes

Tips

  • For the best flavour, brown the aubergine properly before simmering; it should look deeply golden in places.
  • If cooking for anyone vulnerable to foodborne illness, make sure the stew is piping hot all the way through before serving.

Substitutions

  • Replace Red pepper with Yellow pepper for a slightly sweeter finish.
  • Replace Fresh basil with Fresh thyme for a more earthy, Provençal flavour.

Storage

  • Refrigerate up to 4 days
  • Cool completely, then refrigerate in a sealed container. Reheat gently in a saucepan over low heat, stirring, until piping hot; add a splash of water if needed. Freeze in portions for up to 3 months and defrost overnight in the fridge before reheating.
