History of Ratatouille
Ratatouille is a traditional French vegetable stew that originated in Nice, France, in the 18th century. Initially a peasant dish, it was designed to use the abundance of seasonal vegetables. By the 1930s, ratatouille had become a celebrated staple in French cuisine, symbolising the essence of Mediterranean cooking with its emphasis on fresh, seasonal ingredients.
Why this dish is perfect on a diet
Vegetables are low in calories compared to their density. This essentially means that they fill you up with very few calories.
The more vegetables you have in a meal either as a side dish or mixed in with the meal itself the lower-calorie the meal tends to be. A filling but low-calorie meal is perfect for weight loss.
If you follow Slimming World, Weight Watchers (WW), Noom or any other weight loss plan this is a great recipe to try. It is of course important to check yourself any plan you follow and remember all nutritional information and ingredients are found in the recipe card below.

Making ratatouille – top tips
For the best ratatouille, use fresh, ripe tomatoes like beefsteak or heirloom varieties. Globe aubergines and young, small courgettes are ideal. Fresh herbs such as basil and thyme enhance the flavour perfectly, but dried herbs can be used if that is all you have. Consider adding capers for a tangy twist or using fire-roasted tomatoes for a deeper flavour.
To enhance the flavour of your ratatouille, salt the aubergine before cooking to remove bitterness. Use fresh herbs whenever possible for a more vibrant taste. Allow the dish to rest for an hour before serving to let the flavours meld together beautifully. If you prefer a thicker stew, simmer the vegetables longer over low heat.
What to enjoy ratatouille with
This is a great recipe to enjoy with a jacket potato, as a side dish to most meals or even on its own if you like!
The flavours are deep but nothing that children would not enjoy too so perfect for all the family. If a member of your family does not like one of the vegetables in it simply add extra of the others!
Ratatouille is incredibly versatile. Serve it hot, cold, or at room temperature. Pair it with crusty bread, pasta, polenta, or grains like quinoa or rice. For a hearty meal, top it with a fried egg or serve alongside grilled meats and spicy potatoes. It’s also delicious as a side dish to roasted chicken or lamb.
