    What are Baby Marrows?

    Baby marrows are high in fibre, low in fat and rich in antioxidants, making them the ideal veggie for dieters.

    In South Africa, these vegetables are commonly known as baby marrows, but the rest of the world seems to call them either zucchini or courgettes. No matter, it doesn't matter what you call them, they are still delicious. As Shakespeare so aptly put it - A rose by any other name would smell as sweet.

    There are so many ways to prepare baby marrows, but my favourite is to braise them with a mixture of tomato and onion.  The sweetness of the tomato and onion perfectly complements the delicate flavour of the baby marrow.

    A helping of baby marrows with tomato and onion is the perfect vegetable to serve with any roast dinner.

    Recipe information

    • Prep time - 5 minutes
    • Cook time - 20 minutes
    • Calories - 69 per serving
    • Main equipment - I'm sure you all have a saucepan with a lid in your kitchen. In addition to that, you will need a sharp knife and a chopping board.

    Ingredients

    You can get the complete list of ingredients and full instructions on how to make baby marrows with tomato and onion on the printable recipe card at the end of this post.

    Ingredients for zucchini with tomato and onions.

    For 4 people, you will need the following

    • 400g baby marrows (or courgettes or zucchini)
    • 1 cup chopped onion
    • 1 cup chopped fresh tomatoes - you have to use fresh tomatoes. Don't use tinned tomatoes, they contain too much liquid.
    • 1 tablespoon neutral-flavoured oil - Sunflower oil works well.
    • Salt and pepper to taste

    How to make zucchini with tomato and onion

    Steps for making baby marrows with tomato and onions.
    • To prepare the marrows, rinse them in cold water, then pat them dry with a paper towel. There is no need to peel the courgettes. Slice off both ends and then slice the marrow in half, lengthwise. If they are very large, you could cut them in half again. Cut each half into ½" (just over 1cm) slices.
    • Chop the onion and tomato into 1 cm dice.
    • Saute the onions in the oil until they just start to soften. Add the tomatoes, season with salt, and allow to simmer (image 1 above). Cover the pan with a lid for the first 5 minutes and then remove the lid and continue to simmer on low heat until most of the moisture from the tomatoes has evaporated. This will take between 5 and 10 minutes in total.
    • Go easy on the salt - there is no additional water in this dish to be poured away, so all the salt that you add will remain in the dish. You only need sufficient to flavour the vegetables.
    • Once the onions and tomatoes are ready, add the baby marrows (image 2 above), put the lid on the saucepan, and continue to simmer until the baby marrows have softened. This will take about 10 minutes. Keep your eye on it. Don't allow the marrow to over-cook or it will be mushy.
    • Stir the marrows and tomato mixture occasionally to ensure the baby marrows cook evenly.
    • Tip into a serving dish (image 3 above) and serve hot, alongside your favourite roast meat.

    If you want to spice this dish up a bit, you could add a teaspoon of chilli paste with the onions.

    How to peel tomatoes

    I personally don't think it is necessary to peel the tomatoes before cooking them. The tomatoes are cut into small pieces, and the skins are hardly noticeable.

    However, should you wish to peel the tomatoes first, this is the easiest way to do it.

    • Cut a shallow cross through the skin on the base of each tomato.
    • Place the tomatoes in a deep bowl and cover with boiling water.
    • Leave for 2 - 3 minutes and then pour away the water.
    • Peel the tomatoes starting at the cross that was cut into the base. The skins should slip off easily.

    Can I freeze baby marrows?

    Yes - freeze the cooked baby marrows in individual meal-sized amounts in a zip-lock bag or plastic container.

    To use, allow to defrost in the fridge.

    You may find that once defrosted, the marrow has released a lot of water. Just pour this water away before re-heating or the dish will be too watery.

    Reheat them either in the microwave or in a saucepan on the stove. Once the baby marrows start to boil, remove the pan from the heat and serve immediately to ensure the baby marrows do not overcook.

    Variations

    In addition to serving these baby marrows as a side vegetable, they make a delicious pasta dish.

    Just mix the cooked baby marrow, along with the tomato and onion sauce, with a dish of your favourite pasta shapes. Cover with grated cheese and grill or broil until the cheese has melted.

    Cooking the marrows in this way also makes a great side dish to serve at a barbeque.

    Equipment

    • Sharp Knife
    • Chopping Board
    • Saucepan with lid
    • Serving dish

    Ingredients

    • 450 g (1 lb) baby marrows (or courgettes or zucchini) chopped into 2cm chunks
    • 1 cup diced onion cut into 1cm dice
    • 1 cup diced tomatoes cut into 1cm dice
    • 1 tablespoon sunflower oil for frying the onions
    • Salt and pepper to taste

    Instructions

    • Chop the tomato and onion into 1cm chunks.
    • Chop the baby marrows into 2cm chunks.
    • Heat the sunflower oil in a saucepan and add the onions.
    • Fry gently until the onions start to soften (about 4 minutes).
    • Add the tomatoes and a sprinkling of salt. Cover with a lid and leave to simmer for about 5 minutes. Then remove the lid and continue to simmer until the moisture from the tomatoes has almost evaporated. This step should take about 10 minutes altogether.
    • Add the baby marrows t the tomato and onion mix, stir and cover
    • Continue to simmer until the baby marrow has softened. This will take approximately 10 minutes on a low heat.
    • Taste for seasoning and add extra salt ad/or black pepper if needed.
    • Tip into a serving dish and serve with your favourite roast meat.

    Notes

    Baby marrows contain a lot of water, so let most of the water cook out of the tomato and onions before adding the baby marrows. 
    Simmer the baby marrows with the tomato and onion until the baby marrow is just al dente.  Do not overcook or the baby marrow will release too much liquid and become mushy.
    Do not over salt.  There is no water in this dish to be drained away, so all the salt you add will remain in the dish.
