Guacamole can be made in minutes, yet it's surprisingly easy to end up with a bowl that tastes only of onion or has the texture of baby food. The trick is starting with ripe avocados, seasoning a little at a time and deciding whether you prefer it chunky or smooth before you begin mashing.
There is no requirement for a blender or a long list of ingredients. Avocado, lime, salt and a small amount of onion are the foundation of a very good guacamole. Chilli, tomato and coriander add variety, but the ripe avocado should remain the main flavour.
Ingredients for four small servings
Use:
- 2 ripe avocados
- Juice of ½–1 lime, to taste
- ¼ small red onion, finely chopped
- 1 small ripe tomato, optional
- ½ small fresh chilli, optional
- A small handful of coriander, optional
- Salt to taste
- Freshly ground black pepper, optional
This is a deliberately simple, flexible home recipe. BBC Good Food's classic version also uses avocado, red onion, tomato, chilli, lime and coriander, with proportions that can be adjusted for your household.
Pick avocados that are ready to use
A ripe avocado should yield a little to gentle pressure without feeling mushy. Very hard fruit can be difficult to mash and may taste underdeveloped. Fruit with large soft patches may be overripe or damaged.
Don't squeeze every avocado aggressively in the shop. Hold it gently and assess firmness through light pressure; bruising the fruit doesn't help anyone.
If the avocados are still hard, leave them at room temperature to ripen. Once ready, refrigerate them if you won't make guacamole immediately. Check for signs of spoilage before cutting.
Prepare the other ingredients first
Finely dice the onion so nobody gets a huge sharp mouthful in an otherwise creamy dip. If raw onion is too strong for you, use a little less rather than trying to bury it beneath extra lime.
If using tomato, halve it and remove some of the watery seeds before chopping. That helps stop the guacamole turning runny.
Chop coriander and chilli separately. If preparing chilli, keep hands away from your face and wash them thoroughly afterwards. Use the heat level you're comfortable with.
Wash and cut the avocado safely
Rinse the avocado's skin under running water and dry it. Although you don't eat the peel, a knife can carry surface dirt into the flesh.
Place the avocado securely on a chopping board, cut around the stone and twist the halves apart. To remove the stone, use a spoon or a safe removal tool rather than striking it with a knife while holding the fruit in your hand.
Scoop the flesh into a bowl. Discard any sections with clear decay or an unpleasant smell. A little surface browning alone may reflect oxidation, but examine the overall condition.
Mash with a fork, not a food processor
Use a fork to crush the avocado against the sides of the bowl. Leave some small pieces intact if you like a rustic texture.
A food processor can quickly turn a chunky dip into a completely smooth paste. That's a preference rather than an error, but it is harder to reverse once the pieces have disappeared.
If your avocados are ripe, a fork is all the equipment you need. Hard avocados that refuse to mash won't magically become ripe through force.
Add lime a little at a time
Squeeze in about half a lime, stir and taste. Lime adds acidity that balances the richness of avocado and can slow some surface browning.
Don't add the juice of three limes simply because you've heard guacamole needs 'lots of citrus'. Too much can overwhelm the avocado and make the dip thin.
Taste again after adding salt. Salt changes how the acidity and other flavours come through, so it's better to adjust them together than to add one ingredient in a huge amount.
Fold in onion, tomato and herbs
Stir in the chopped onion, then add tomato, coriander and chilli if you're using them. Fold gently so the ingredients remain recognisable.
Reserve a little coriander or tomato for the top if you're serving the bowl to guests. A small colourful garnish looks better than a pile of wet chopped vegetables dumped in the centre.
Some traditional guacamole styles omit tomato entirely. If you prefer a stronger avocado flavour, leave it out and use only onion, chilli, lime and salt.
Taste before serving
Take a small clean spoonful and ask what is missing. Flat guacamole may need a touch more salt or lime. Overly sharp guacamole may be improved by adding more ripe avocado.
If the chilli heat is too strong, adding more avocado may balance it, but removing the heat entirely isn't possible once the chilli has been mixed in.
Allow the dip to retain its natural texture. It shouldn't be a watery salsa with a few avocado pieces floating in it unless that is the dish you intended.
What to serve with guacamole
Tortilla chips are the obvious choice, but guacamole is also good with fajitas, tacos, burrito bowls, baked potatoes and fresh vegetable sticks.
For a simple lunch, spread it on toast with tomatoes or a cooked egg. Keep the rest of the meal in mind before adding lots of chilli or garlic to the dip.
Use a clean spoon when serving and don't return a spoon that has touched raw meat or other uncooked ingredients to the guacamole bowl.
Can you make guacamole ahead?
You can, but it looks best when prepared close to serving. Exposed avocado browns through oxidation, and a dip left open for hours may develop a darker surface.
Press a suitable food-safe covering directly against the surface to reduce air contact and refrigerate promptly. Use a clean lidded container and keep it at a safe chilled temperature.
Lime helps with colour to an extent, but it is not a preservative that makes room-temperature storage safe. Guacamole is a prepared perishable food and should be handled as such.
Why guacamole turns brown
When cut avocado contacts oxygen, compounds in the flesh react and the surface may darken. The effect is more noticeable in a shallow bowl with a large exposed surface.
Darkening isn't always spoilage, but don't ignore off smells, mould or unsafe storage because browning is 'just oxidation'. The colour alone cannot establish food safety.
A tight covering, less air exposure and refrigeration reduce the problem. Making smaller batches is often more effective than trying complicated tricks to keep a huge bowl green for days.
Why homemade guacamole is watery
Very juicy tomatoes and excessive lime are frequent causes. Remove some tomato seeds and add citrus gradually.
A completely overripe avocado may also break down into a thin paste rather than holding chunky texture. Start with ripe but sound fruit for a better result.
If the dip has already become watery, a little additional mashed avocado can thicken it. Don't stir in flour or other thickeners simply to disguise the problem.
Can you leave out coriander or chilli?
Absolutely. Coriander tastes unpleasantly soapy to some people, and a bowl made for young children may not need fresh chilli.
Guacamole is flexible. Lime, avocado and an appropriate amount of salt can make an appealing dip without every traditional optional ingredient.
You can also add a tiny amount of finely chopped garlic if you like it. Begin sparingly, because raw garlic can dominate the flavour of two avocados.
A simple method worth repeating
Chop the extras first, mash the ripe avocado, add lime and salt carefully, then fold in onion and whatever else you prefer.
Serve immediately or cover closely and chill until required. Wash the utensils and put any leftovers away promptly.
The point isn't to create the world's most complicated guacamole. It's to make one that tastes of fresh, ripe avocado, with the other ingredients there to support it.
