Mediterranean vegetable stew

This is a great Mediterranean vegetable stew recipe that uses tasty sun-kissed Mediterranean vegetables that are packed with plant compound nutrients that are antioxidant-rich and full of health benefits.

The preparation is very simple using a great cooking hack that keeps time down and locks in all the goodness and fresh flavour without compromising on taste or texture. Our colourful Mediterranean vegetable stew is a real crowd pleaser which we have based on a traditional French ratatouille which is a classic rustic dish prepared with juicy tomatoes, crisp courgette/zucchini, ripe aubergine/eggplant, soft mellow onions and sweet peppers. Arguably, a simple ratatouille cannot be bettered but we have given it a little bit more substance and flavour by preparing the stew with a mirepoix first and then by giving it a depth of flavour with umami filled rich organic vegetable stock. Also known as a Provencal stew, this classic staple originated in Nice using vegetables prevalent in the area that grow in the hot Mediterranean sun. However, using a mirepoix which is the basis of many soups, stews and casseroles, the addition of a mirepoix, which is chopped carrots, leeks and celery not only help pack this with even more healthy vegetables but also adds more flavour and texture.

Tasty Mediterranean vegetables in a tomato sauce

Perfect all year round

Even though a vibrant Mediterranean vegetable stew that is born in the heat of the south of France it is fresh and juicy enough to eat in the hot months, but there is something very warming and hearty that makes this an ideal filling meal for the colder months too. Moreover, this is not a slow-cooked stew that will gently bubble away for hours, we use a flash grilling technique to cook the vegetables which make this quick and very convenient to make too.

Set your grill/broiler to the highest level and place your chopped vegetables dressed in some healthy extra virgin olive oil under it. You only need to cook them for 10 minutes for them to be beautifully charred but with a slight al-dente bite. This really keeps them very tasty. By cooking them in this method you will also help them retain much of the nutrients contained within the Mediterranean vegetables that will have greater health benefits. 

The sauce does, however, require a slightly longer time to cook. Reducing the tomatoes and stock intensifies the flavour. The carrots, leeks and celery flavours will also meld into the stew too. For the tomato aspect, we like to use tinned tomatoes. You could use a passata or chopped tomatoes, but we have found tinned whole Italian cherry tomatoes which just seem to explode with flavour. Start the sauce by adding a glug of olive oil to a pan and add the chopped leeks, carrots and celery over medium heat. Add a couple of cloves of chopped garlic and stir-fry them for about 4 minutes. Pour in the tinned tomatoes, 400ml of good organic vegetable stock and a tablespoon of tomato puree. The sauce will only need to bubble away for about 15 minutes. Then all that remains is to add the grilled vegetables and warm them through with a lid on for a few minutes. Serve this gorgeous stew with some crisp ciabatta slices slathered with tasty olive tapenade or your favourite mash. 

Hearty healthy Mediterranean vegetable stew

An easy stew recipe that is high in antioxidants 

With the bulk of the vegetables being cooked very quickly so that their nutritional content is maximised, the cooking however of the tomatoes to intensify their flavours actually intensifies one of the antioxidants they contain too. Lycopene is a potent antioxidant contained in tomatoes. It is an important dietary carotenoid which makes up around 50% of all carotenoids found in the body. It is the red pigment found in fruit and vegetables, namely tomatoes but also grapefruits, watermelons, guava and papaya amongst others. Cooking tomatoes releases five times more lycopene than you would get by consuming just them raw. Although Lycopene is not essential for humans, studies have suggested that there is a strong link between tomato intake and the reduced risk of many cancers. Whether or not this correlation of eating tomatoes is directly associated with reducing the risk of cancer, in fact, it is certainly a marker as eating a tomato-rich diet would certainly sit alongside a lifestyle choice of generally being healthier.     

Mediterranean vegetables

Our other vegetables are also incredibly healthy too with the plant compounds they contain. Aubergines/eggplants contain solasodine rhamnosyl glycosides (SRGs). Test tube studies have shown that these compounds could potentially stimulate the programmed death of cancer cells. The skin also contains a compound that protects the vegetable called nasusin which also has potent antioxidant capabilities too.

Courgette/zucchini contains a whole host of antioxidants too including lycopene, beta carotene and lutein. It also has high water content and is a great vegetable to aid weight management. 

Onions are bulbs from the allium genus and are related to garlic and leeks which we also use. These vegetables have been used medicinally for millennia as it has been long known that they can stave off illness due to their high vitamin C concentration. 

They also contain anthocyanin, the pigment responsible for giving red onions their colour which is also a potent antioxidant that fights inflammation at a cellular level in the body. 

Onions are also high in vitamin B which is essential for metabolism and nerve function and potassium which is vital for aiding proper kidney functions. Quercetin contained in onions is also being studied for its potential capability of impairing tumour growth as is a compound known as onionin A. 

Red capsicum peppers are not only sweet and crunchy they also add to the melee of health benefits too. They are high in vitamin C which as an antioxidant helps boost your immune system to fight microbes. The A and Beta carotene content also aid your white blood cell count too.  

These ingredients start to look like a list for the pharmacy, but Hippocrates did say “let food be thy medicine”.
