Chilled Avocado and Cilantro Soup with Crunchy Tortilla Strips

A chilled avocado and cilantro soup is the sort of bowl that makes warm-weather cooking feel effortless. It is creamy without relying on dairy, brightened with lime and fresh herbs, and finished with crisp tortilla strips that bring a savoury crunch to every spoonful. The texture sits somewhere between a silky gazpacho and a pourable avocado dip, making it substantial enough for lunch while still feeling light. Learn more about Desserts.

In Australia, this soup is especially welcome during a hot spell, whether you are serving it on a shaded veranda in Brisbane, before a barbecue in Adelaide, or as a cool first course on a humid Sydney evening. Australian cooks generally call cilantro “coriander”, so both names belong in the kitchen here. Use ripe Hass avocados, punchy local limes and coriander that looks perky rather than tired, then serve the soup very cold.

Build the flavour around freshness

Avocado gives the soup its mellow richness, but it needs acid and aromatics to keep the flavour lively. Lime juice is the natural partner, adding a clean, almost floral sharpness. A small amount of jalapeño supplies gentle heat, while garlic and spring onion add savoury depth without overpowering the green ingredients. If you prefer a softer chilli note, remove the seeds and white membrane before blending.

Coriander stems are worth using as well as the leaves. They contain plenty of flavour and blend smoothly, particularly when roughly chopped first. A little ground cumin gives the soup a warm, earthy background, while vegetable stock loosens the mixture and helps all the flavours travel across the palate. Start with less salt than you think you need, chill the soup, then taste again; cold food often needs a final seasoning adjustment.

For a slightly more layered finish, add a teaspoon of honey or agave if your limes are unusually sharp. You can also stir through a small spoonful of sour cream, Greek yoghurt or coconut cream, though the soup is beautifully creamy without any of them. The key is balance: rich avocado, tart lime, fresh coriander, modest chilli and enough salt to make the flavours distinct.

Choose and prepare the ingredients

For four generous entrée servings, use three ripe Hass avocados, one and a half cups of cold vegetable stock, the juice of two limes, one packed cup of coriander leaves and tender stems, two sliced spring onions, one small garlic clove, half a deseeded jalapeño, half a teaspoon of ground cumin and salt to taste. Keep a little extra lime, coriander and chilli nearby for finishing.

A ripe avocado should yield slightly when pressed near the stem end, but it should not feel watery or collapse under your fingers. If your avocados are still firm, leave them at room temperature for a day or two. In Australia, the best choice may shift with the season and your location: produce from Queensland, Western Australia and the Riverina can appear at different times, so judge the fruit by texture rather than relying on a fixed calendar.

Add the avocado flesh, stock, lime juice, coriander, spring onion, garlic, jalapeño and cumin to a blender. Blend until completely smooth, pausing to scrape down the sides. A high-speed blender creates the most velvety result, although a stick blender works well in a tall jug if you blend patiently. If the soup is too thick to move freely, add cold stock one tablespoon at a time.

Make the soup silky and well chilled

Once blended, taste the mixture for salt, lime and heat. The flavour should seem slightly more intense than you want at serving temperature because chilling softens the perception of seasoning. If it tastes flat, add salt first; if it tastes heavy, add another squeeze of lime. A tablespoon of cold water can make the consistency more spoonable without diluting it too much.

Transfer the soup to a covered container and refrigerate for at least two hours. This resting time does more than cool the bowl. It allows the garlic, coriander and spring onion to settle into the avocado, producing a rounder flavour. Press a piece of baking paper or reusable wrap directly on the surface if you want to limit discolouration, then seal the container with its lid.

Avocado can darken when exposed to air, but lime juice slows the process. For the freshest colour, make the soup on the day you plan to serve it. It can be prepared several hours ahead, which makes it useful for entertaining. Give it a vigorous stir before ladling, as the thicker avocado mixture may settle slightly during refrigeration.

Crisp the tortilla strips properly

Corn tortillas give the soup a more authentic contrast than flour tortillas, and they are easy to find in larger Australian supermarkets, specialty grocers and Latin American food shops. Cut six small tortillas into thin strips or narrow wedges. Toss them with a tablespoon of neutral oil, a pinch of salt and, if desired, a little smoked paprika or ground cumin.

For oven-baked strips, spread them in a single layer on a lined tray and bake at 190°C fan-forced for approximately eight to twelve minutes. Turn them once, watching closely near the end because thin tortilla pieces go from golden to burnt quickly. They should be crisp and lightly browned around the edges. Cool them completely before serving so they retain their snap.

You can also fry the strips in a shallow layer of oil for a deeper toasted flavour. Work in small batches, then drain them on paper towel and season while hot. In a warm Queensland kitchen, avoid covering the strips while they are still steaming; trapped moisture will soften them. Store cooled strips in an airtight container for a few hours if you are preparing them ahead.

Finish each bowl with contrast

Pour the cold soup into chilled bowls, small glasses or wide cups. Scatter the tortilla strips over the surface at the last moment so they stay crisp. Add a few drops of olive oil, a spoonful of finely diced avocado, sliced spring onion and a few coriander leaves. Thinly sliced radish, roasted corn kernels or a pinch of flaky salt can bring extra colour and texture.

For a more substantial lunch, top each serving with a little flaked cooked chicken, prawns or black beans. Keep the additions restrained so the soup remains the centre of the dish. A few grilled prawns would suit a coastal summer gathering, while black beans and roasted corn make a satisfying plant-based version. If you are serving this before a barbecue, small portions work best.

The fresh, sharp character also makes it a good partner for a simple main course. Try it before zesty roasted chicken, where the lime and coriander echo the citrus in the chicken while the tortilla strips provide a different sort of crunch. A crisp lager, dry riesling or sauvignon blanc will suit the soup, and sparkling water with lime keeps the meal alcohol-free and refreshing.

Adapt it for the season and the table

The basic recipe is flexible enough for different preferences. Replace part of the vegetable stock with chilled coconut water for a lighter, subtly sweet version, or blend in half a cucumber for extra freshness. A small roasted green capsicum can add sweetness and depth, while a little fresh ginger gives the soup a lively edge. For more heat, include the jalapeño seeds or use a small green chilli.

If coriander is divisive at your table, use half coriander and half flat-leaf parsley. The result will be gentler but still green and herbaceous. You can also garnish individual bowls differently, allowing guests to choose chilli, herbs or tortilla strips according to taste. This is useful when feeding children or anyone who prefers mild food.

A bright salad makes a natural companion, particularly one dressed with a sharp homemade vinaigrette such as this tangy vinaigrette. Keep the salad crisp rather than creamy so the meal does not become too rich. For dessert, something citrus-led or fruit-based will continue the fresh theme; browse these simple dessert recipes for ideas that will suit a warm afternoon.

When the weather turns cooler, serve the soup in smaller portions as a starter rather than abandoning it altogether. The flavour remains appealing year-round, especially when avocados are plentiful. Keep leftovers refrigerated and use them within a day, stirring well before serving. The tortilla strips should always be stored separately and added just before eating, preserving the contrast between smooth, chilled soup and crisp, salty crunch.
