Furthermore, it's an extremely simple and quick recipe , ideal for those who don't want to complicate things in the kitchen but are looking for a truly sensational result.
Ingredients needed for 4 or 5 people

To achieve that ideal consistency, we will need the following components:
- 2 large zucchini (approximately 750 g).
- 2 leeks (about 140 g), using mainly the white part.
- 2 medium potatoes (about 200 g) to give body.
- 50 ml of white wine to deglaze and add aroma.
- 800 ml water or chicken broth to intensify the flavor.
- Extra virgin olive oilsalt and ground black pepper.
- Optional for creaminess: 2 or 3 cheeses, 50 ml of cream or evaporated milk.
- To decorate: Croutons, toasted bread, chia seeds, fried almond flakes or ham cubes.
Step-by-step preparation

The secret to a good cream soup starts with cleaning. We must remove the outer layer of the leeks and wash the inside well to remove any traces of sand. It is recommended to slice them thinly and reserve the green part for future broths. On the other hand, we will peel the potatoes and cut them into quarters and then into slices so that they cook evenly.
In a pot with a drizzle of oil and a pinch of salt, sauté the leek over medium heat for about 5 minutes. It's essential to prevent it from browning too much so the flavor remains mild; if it starts to stick, add a little water. Next, add the potato and cook for another 5 minutes.
Meanwhile, dice the zucchini. You can leave the skin on to retain all the vitamins and minerals , or peel them if you prefer a lighter color and an even smoother texture. Add the zucchini to the pot and sauté everything for an additional 5 minutes.

To enhance the flavor, turn up the heat and pour in the white wine, letting the alcohol evaporate completely for a couple of minutes. Then, add the water or stock. A pro tip is to cover the vegetables right up to the rim; if you prefer a less dense texture, you can add the full 800 ml, but if you want more control, start with 600 ml and adjust at the end.
Cover the pot and let everything simmer over medium heat for 15 to 20 minutes. It's ready when a potato is completely tender when pierced with a fork. Remove from the heat and mash, either with an immersion blender or a food processor.
If you've decided to use cream cheese, heavy cream, or evaporated milk, now's the time to add them and whisk everything together until you achieve a perfect emulsion. For those who prefer a restaurant-quality texture, you can pass the cream through a fine-mesh sieve to remove any lumps.
Variations and tips to personalize your mashed potatoes

If you want to experiment, you can add other vegetables like carrots, squash, onions, or even artichokes and mushrooms. For an international touch , cumin or paprika work very well, while curry adds an exotic hint. A tablespoon of soy sauce will give it a very interesting Asian flavor.
For those preparing food for children, zucchini can be substituted with sweet potato or carrot, using a vegetable stock cube to simplify the process. It's important to remember not to burn the vegetables during the stir-fry, as any charred bits will impart an unpleasant bitter taste to the final result.
As for storage, this cream keeps perfectly in the refrigerator for 2 or 3 days in an airtight container. It can also be frozen without any problems , as the amount of potato is balanced and the purée's texture is not altered upon thawing.
This dish represents the perfect balance between health and flavor, allowing us to play with thickeners like potatoes or dairy to adjust the consistency to our liking. Whether served with a drizzle of extra virgin olive oil, freshly ground pepper, or crunchy elements like nuts, it becomes a comforting and versatile option for any time of day.
