Ratatouille
Why this recipe works
- Layered vegetable flavour: Cooking the onion, garlic, pepper and aubergine in stages helps each vegetable develop flavour before the stew simmers.
- Balanced finish: Tomato purée deepens the savoury base, while balsamic vinegar adds brightness to balance the sweetness of the softened vegetables.
- Excellent made ahead: The flavours settle and become more rounded after resting, making this a practical dish to cook in advance.

Ingredient notes
- Use ripe tomatoes: Ripe plum tomatoes give the stew natural sweetness and a fuller sauce; underripe tomatoes can taste sharper and less rounded.
- Keep the pieces even: Cutting the vegetables to a similar size helps them cook at the same pace while keeping the stew spoonable rather than mushy.
- Fresh or dried thyme: Fresh thyme gives a softer herbal aroma, but dried thyme works well if added with the tomatoes so it has time to infuse.
Texture tips
- For more defined vegetables: Simmer gently and stop cooking when the aubergine and courgette are tender but still holding their shape.
- For a thicker stew: Uncover the pot near the end of cooking so excess moisture can evaporate and the tomato base can reduce slightly.
Make-ahead tips
- Good the next day: Ratatouille is well suited to making ahead because the herbs, garlic and tomato flavours continue to meld as it rests.
- Freeze in portions: Cool completely before freezing in sealed portions, then defrost overnight in the fridge before reheating.
- Reheat gently: Warm it over low heat, stirring occasionally, and add a splash of water if the sauce has thickened too much.
Authenticity notes
- Provençal roots: Ratatouille is closely associated with Provençal cooking, where summer vegetables, olive oil, garlic and herbs are used to create a simple, deeply savoury stew.
- Rustic rather than arranged: This version follows the rustic stewed style rather than the neatly layered presentation often seen in modern interpretations.

Ingredients
Instructions
- Prepare the vegetables: peel and finely slice the onion, finely slice the garlic, deseed and cut the red pepper into bite-size pieces, and cut the aubergine and courgettes into 2 cm chunks. Roughly chop the tomatoes.
- Heat 2 tbsp of the olive oil in a Dutch oven over medium heat. Add the onion with a pinch of salt and cook for 8 to 10 minutes, stirring, until soft and lightly golden.
- Stir in the garlic and cook for 1 minute until fragrant. Add the red pepper and cook for 5 minutes, stirring occasionally, until it begins to soften.
- Add the remaining 2 tbsp olive oil, then add the aubergine and cook for 6 to 8 minutes, stirring, until the edges start to colour. Add the courgettes and cook for 3 minutes to coat in the oil.
- Stir in the tomatoes and tomato purée, then add the thyme sprigs and bay leaves. Bring to a gentle simmer, then reduce the heat to low, cover, and cook for 18 to 22 minutes until the vegetables are tender but not collapsing.
- Uncover and simmer for 5 to 8 minutes to thicken slightly. Stir in the balsamic vinegar, then remove the thyme sprigs and bay leaves before serving.
Recipe notes
Tips
- Cut the vegetables to a similar size so they soften at the same rate and the stew stays nicely textured.
- Keep the heat low once it simmers; ratatouille should cook gently so the vegetables turn silky rather than breaking down.
- If serving to anyone who is vulnerable, make sure the stew is piping hot all the way through before serving.
Substitutions
- Replace Balsamic vinegar with red wine vinegar for a brighter, less sweet finish.
- Replace Fresh thyme with dried thyme, using a smaller amount, and add it with the tomatoes.
Storage
- Refrigerate up to 4 days
- Cool completely, then refrigerate in a sealed container. Reheat gently in a saucepan over low heat, stirring occasionally, until piping hot; add a splash of water if it looks dry. Freeze in portions for up to 3 months and defrost overnight in the fridge before reheating.
