Method
- 1
Heat 1 tablespoon of olive oil in a large frying pan over a medium heat. Add the diced onion and cook for 3–4 minutes until softened, stirring occasionally. Add the minced garlic and cook for a further 1 minute until fragrant.
~5 minsTip: This softening of the aromatics helps build flavour before transferring to the slow cooker
- 2
Add the diced aubergine and courgettes to the pan and stir well to coat with the oil. Cook for 3–4 minutes, stirring occasionally, until the aubergine begins to soften slightly. This helps prevent the aubergine from absorbing too much liquid in the slow cooker.
~4 mins - 3
Transfer the sautéed vegetables to your slow cooker. Add the diced red and yellow peppers, chopped tomatoes, stock (if using), the remaining 2 tablespoons of olive oil, dried herbes de Provence, salt, and freshly ground black pepper. Stir well to combine all ingredients.
~2 minsTip: Mix thoroughly to distribute the herbs and seasonings evenly

Cover the slow cooker and cook on Low for 6 hours or High for 4 hours. The vegetables should be tender but not falling apart, and the flavours should have melded beautifully together.
~6 hrsTip: Cooking time will depend on how soft you prefer your vegetables

In the final 15 minutes of cooking, stir in the fresh basil. Taste and adjust the seasoning with additional salt and pepper as needed.
~15 minsTip: Adding basil at the end preserves its fresh flavour and vibrant green colour
