Easy Zucchini Soup Recipe – Crema de Calabacín

Here comes this easy zucchini soup recipe from Andalusia, called Crema de calabacín in Spanish, and a perfect addition to this collection of zucchini recipes for springtime, when there’s a glut of zucchinis coming your way.

Bowl of zucchini soup or crema de calabacín

If you’re anything like me, you always have too many zucchinis at this time of year! Mind you, I’m not complaining about that! I loooove zucchini so much that I even added it to my fruit bowl the other day (yes, weird, I know!).

And don’t worry, if you don’t have a veggie garden full of zucchinis, you can still make this easy zucchini soup. Just be sure to buy sweet zucchinis (see below).

So far this year I’ve made this delicious zucchini layers casserole which really surpassed all my expectations. And then there’s the potato, zucchini & beetroot casserole, where the beetroot took star role and also a zucchini carpaccio salad, not to mention my favourite grilled summer vegetable salad which I created after visiting Bordeaux and eating something similar there.

I’ve also made nasi goreng and bami goreng, with zucchini as the star player, and of course we’ve dined on grilled & roast zucchini loads of times. I think by the time the glut of peppers arrives, my husband might be glad not to see another zucchini!

And today it’s time for some of this tasty cream of zucchini soup from Andalusia.

It’s such a simple dish, quick and easy to put together, and always tasty. Though the funny thing is that you can make the same recipe loads of times and yet it will always come out tastier some times than others. Funny that.

Anyway with this recipe, best case scenario is that is tastes out-of-this-world, worst case scenario it’s just delicious.

The best way to eat it is on the second day, and I love to eat it chilled, straight from the fridge, in place of gazpacho. But you can also eat it hot, immediately. Or make far too much quantity and have it hot one day and cold the next.

Homegrown vs Shop Zucchini

I’m an absolute fan of homegrown zucchinis but of course not everyone has the space, time or inclination to grow these 5 foot monster plants in their garden.

Size of zucchini

If left on the plant, a zucchini grows up to be what in the uk, we call a a marrow. A marrow is basically a big fat round zucchini with a tough skin and much dryer flesh.

The taste isn’t really comparable, and although they still have a place in the kitchen, they need to be cooked differently. So for the purpose of this recipe, we’re talking about young, fresh zucchini.

Within that category, there are lots of different types and they have different colours and different sizes. An English ‘courgette’ as it’s called, is tiny compared to one you’ll buy in Spain. And very, very small compared to the ones that come from my garden.

So beware when following recipes, and just use the amount you want and think is right for whatever you’re making.

Apart from size, the creaminess of homegrown zucchinis is different to the ones from the shops, and if you’ve ever tried a bitter zucchini you might even be forgiven for thinking you don’t like zucchinis (gasp). Don’t worry, all is not lost, you just need to get your hands on some tasty ones.

How to Choose Your Zucchini in the Shop

When you go shopping for zucchini, it’s important to pick ones that still have a shine on their skin. When they get old (both on the plant and off), they lose their shine and the skin becomes decidedly dull. They’re still edible at this stage, but they can be tough skinned (too mature on the plant) or dry (too old on the shelves), or both.

The other essential thing to check is that they’re hard. When a zucchini goes soft it becomes dry and (often) bitter. And that definitely won’t lull you into loving it. And if they’re really soft, they can just be downright horrible

Of course, if you can’t get perfect zucchinis, you can make do with dull ones that are slightly soft but remember that you’re not getting the creme-de-la-creme! And if it’s bitter, don’t eat it (see below).

Some Interesting Zucchini Facts

  • Zucchinis are low in calories, high in fibre and nutrient dense. They’re helpful in promoting eye health, heart health & weight loss, while helping maintain blood sugar levels and managing diabetes.
  • Zucchinis are classified as a summer squash and are harvested when still immature, before their skins toughen up.
  • They’re a member of the cucurbitaceae family, the same family as pumpkin, gourd, melon and cucumber.
  • Wild Zucchinis contain high levels of cucurbitacins, a toxin to protect the zucchini from predators (herbivores!), while cultivated zucchini have very low levels of this bitter, toxic substance. However, as the cucurbitacins increase, so the zucchini becomes more bitter, so if you have a bitter zucchini, it’s best to throw it away. Curcurbitacins can cause severe gastric symptoms (see next point).
  • Toxic squash syndrome (the name for cucurbitacins poisoning) is rare but it is potentially very harmful and even fatal so it’s best not to eat wild, ornamental or bitter squash. And just throw away your zucchini if it’s very bitter.

Different Ways to Cook Zucchini

  • Zucchini can be sliced very thinly and used in salad, just like you would use a cucumber. It can also be marinated in a little lemon juice and served as a zucchini carpaccio salad.
  • Spiralize the zucchini and drop into boiling water, then serve as zucchini noodles with your favourite pasta sauce like this best homemade tomato sauce for example.
  • Chop it up and put it straight into a sauce (raw) and allow it to cook in the juice of the sauce.
  • Fry the zucchini by cutting fat zucchini wedges and fying in olive oil and a little salt. Add chopped garlic if you like.
  • Make a gluten free batter and fry the sliced zucchini after dipping it into the batter mix.
  • Bake the zucchini in the oven, sliced in half lengthwise and brushed with a little olive oil and garlic, or fill it with a stuffing.
  • For soups, the zucchini can be stir-fried or directly cooked in the water. For this recipe the zucchini only spends a quick stirring moment in the olive oil before you add the liquid.

How to Make Cream of Zucchini Soup

So here goes . . . it’s this simple. You’ll need 5 ingredients (plus salt & spices if using).

Simply fry some onion, garlic in olive oil and then add some chopped potato. Next comes the zucchini and finally, water to cover and add a handful of cashews. Make sure to use enough seasoning as the salt really brings out the flavour. Add what you think, then taste, and then add some more.

The important part of this recipe is the cooking of the onions and garlic, and using enough salt to bring out the flavour. The potato and zucchini can be fried to a greater or lesser degree before adding the water, but the onion should definitely be already flavoursome.

Cook everything in the water until soft through, then leave to stand and cool. Blend into a creamy soup and taste to check the seasoning and overall flavour.

Serve for lunch with gluten free bread, on its own or as a side dish. Or as chilled soup the following day.

If you think there’s too much water, reserve some before blending and just add the amount needed to get a lovely thick creamy soup. Save the removed water for adding to the soup for the following day as it will have lots of nutrients and dense flavour in it.
