Yes — use mayonnaise instead of hummus 1:1 (in sandwiches). The recipe asks for hummus — a sandwich spread, a wrap, a mezze plate — and you have mayonnaise. The swap is 1:1 in sandwiches, and it is a swap of character: hummus is thick, earthy and savoury, while mayonnaise is smooth, rich and neutral, so the sandwich changes its personality even though the amount stays the same.
How much mayonnaise to use
| Hummus in the recipe | Mayonnaise to use |
|---|---|
| 1 tbsp | 1 tbsp |
| 1/4 cup | 1/4 cup |
| 1/3 cup | 1/3 cup |
| 1/2 cup | 1/2 cup |
| 3/4 cup | 3/4 cup |
| 1 cup | 1 cup |
| 2 cups | 2 cups |
The ratio is 1:1 (in sandwiches). All amounts above are approximate — measure with a tablespoon or a measuring jug, and taste as you go.
Worked example 1: a roasted vegetable sandwich
A sandwich asks for 2 tablespoons of hummus spread on sourdough under roasted peppers and courgettes. Use 2 tablespoons of mayonnaise instead and the sandwich will be richer and smoother, with less of the earthy, nutty depth that hummus gives. It works, because the vegetables are the star, but add a squeeze of lemon to the mayonnaise — hummus brings acidity from its lemon juice, and without it the sandwich can taste flat.
Worked example 2: a wrap
A wrap asks for 1/4 cup of hummus to bind grilled chicken and salad. Use 1/4 cup of mayonnaise instead, thinned with a teaspoon of water so it spreads evenly rather than sitting in a thick line. The wrap will be creamier and less substantial — hummus adds body and protein, while mayonnaise adds only fat — so add an extra handful of salad or a slice of cheese to make up the substance. Roll it tightly, because mayonnaise is more slippery than hummus.
Worked example 3: the wrong recipe — a mezze plate
A mezze plate asks for hummus as one of its dishes, and you put out mayonnaise instead. It is not a swap at all: hummus is a dish in its own right, with chickpeas, tahini, lemon and garlic, and mayonnaise is a condiment. The lesson is that the swap only works when hummus is playing a supporting role — a spread in a sandwich — and not when it is the dish itself.
What changes when you use mayonnaise
Texture is the first thing that changes, flavour the second. Creamy spreads all swap 1:1 in sandwiches and dips, so the amount never needs maths, but richness and tang shift with every choice. Mayonnaise is the richest and the most neutral, with a smooth, almost silky body. Sour cream is tangier and a little looser, and it thins when it warms. Greek yogurt is the tangiest and the lightest, with a fresh acidity that wakes up a sandwich but can curdle if it is heated hard. Hummus is thicker and earthier, with a nutty, savoury depth, and mashed avocado is the softest and most buttery, but it browns within the hour. The practical difference is heat: mayonnaise splits when it is heated, so it belongs in cold food, while sour cream and yogurt can be warmed gently but should never be boiled. Choose by the job — richness, tang, or freshness — not just by what is in the fridge.
When not to substitute
Do not use mayonnaise where hummus is the dish — mezze, dips served on their own, and anything where chickpeas and tahini are the point. Do not heat mayonnaise, and do not use it when someone at the table needs the protein or fibre that hummus provides. If the sandwich is vegetarian, remember that mayonnaise adds nothing of substance, so the filling needs to carry the meal.
Method and source
The 1:1 ratio comes from the CookScale substitution data, which records that creamy spreads swap 1:1 in sandwiches and dips and that richness and tang are what change. This is a spoon-for-spoon swap, so no weighing or density figure applies; a tablespoon of one spread replaces a tablespoon of another. Treat the result as approximate: brands vary in thickness, especially Greek yogurt and hummus, so spread a little, taste, and add more rather than piling it on at once. The same data warns not to heat mayonnaise — it splits — and that warning is the one rule in this family that has no exceptions.
Practical guidance
Keep these spreads in small tubs and label the date you opened them, because a swap made with a tired tub is worse than no swap at all. Sour cream and Greek yogurt keep about two weeks once opened; mayonnaise keeps much longer, and hummus about a week. If you are swapping for health reasons, Greek yogurt is the lightest choice, but add it at the end of cooking and keep the heat low, or stir it in off the heat entirely. For sandwiches, spread the wetter ingredient — yogurt or sour cream — on the bread first and add the filling on top, so the bread does not go soggy. And when avocado is the substitute, a squeeze of lemon juice buys you an extra hour before it browns.
Add a squeeze of lemon juice to the mayonnaise to replace the brightness that hummus brings, and consider a smear of mustard or a pinch of cumin for the savoury depth. A little seasoning goes a long way when the spread itself is neutral.
Buying and storing
A spread that has been open for a while can still be good, but check it before you use it in a swap: taste a little on its own, and if it is sharper than you remember, use a little less of it and let the other ingredients carry the dish. Hummus dries out once it is open, so press cling film directly onto the surface before you put the lid on, which keeps it smooth. Avocado browns within the hour, so mash it just before you need it, and add lemon juice the moment it is mashed. Mayonnaise is the most forgiving of the family — it keeps for weeks — but it picks up fridge smells, so keep the lid on tight and do not leave it open on the counter while you cook.
Frequently asked questions
Can I use mayonnaise instead of hummus in a sandwich?
Yes, 1:1. The sandwich will be richer and smoother but less earthy and less filling. Add a squeeze of lemon juice to replace the brightness hummus brings.
Is hummus healthier than mayonnaise?
Yes — hummus has fibre, protein and far less fat, while mayonnaise is almost pure fat. If health is the reason for the swap, the direction is usually the other way round.
Can I use mayonnaise instead of hummus as a dip?
Not well. Hummus is a dip in its own right, with chickpeas and tahini, while mayonnaise on its own is a thin, plain dip. Mix mayonnaise with yogurt and garlic if you need a quick dip, but it will not taste like hummus.
Does mayonnaise work in a wrap instead of hummus?
Yes, but thin it with a teaspoon of water per 1/4 cup so it spreads evenly, and add extra filling — mayonnaise adds no substance, while hummus adds body and protein.
