Two supermarket peanut butters beat the brands on taste in our test – and one is a steal at just 85p per tub.
More than 60 peanut butter fans munched their way through crunchy spreads from Sun-Pat, KP and Whole Earth, as well as supermarket own-brands, including Aldi, M&S, Tesco and more.
The products were anonymised and tasted in a random order, so testers didn’t know which one they were rating.
Supermarket own-labels triumphed, with M&S and Lidl options coming out on top.
Top three crunchy peanut butters
- Best Buy: M&S Crunchy Peanut Butter, 77% (£1.60 for 340g), available from M&S (in store)
- Best Buy and Great Value: Lidl Mister Choc Crunchy Peanut Butter, 75% (85p for 340g), available from Lidl (in store only)
- Great Value: Asda Crunchy Peanut Butter, 74% (£1 for 340g), available from Asda
Lidl’s Mister Choc Crunchy Peanut Butter came a close second and is a brilliant cheap option at less than half the price of branded versions, while Asda’s tasty bargain butter was only a fraction behind the best-tasting spreads.

Peanut butter vs other nut butters
Alternative nut butters, such as almond and cashew, have become increasingly popular, but are often pricier. So are they really all that different?
Nutritionally speaking, not really. Peanut, almond and cashew butter are fairly similar – all will be high in healthy fats and protein, and provide fibre, B vitamins and vitamin E. They will all taste slightly different, though. For example, cashew butter is creamy and mild, which can make it a good alternative to dairy for cooking.
The biggest thing to watch out for with cheaper versions of nut butters is added sugar, salt and oils. This can vary so check the packaging for a nutrition breakdown.
Costs for different types of nut butter can vary quite significantly, too.
Peanut butter tends to be the most affordable option. For example, one of the cheapest peanut butters we tested came from Aldi, costing just 25p per 100g. But Aldi’s almond and cashew butter alternatives cost more than three times as much at 99p per 100g.
Don’t forget sunflower seed butter – this is similar to other nut butters, but you can still eat it if you’re allergic to peanuts and tree nuts.
How we tested crunchy peanut butter
We tested 11 brands of crunchy peanut butter including Whole Earth, Sun-Pat and KP as well as supermarket own-label options, including those from Aldi, M&S and Tesco.
We focused on mid-range peanut butters that weren’t 100% whole nut based as these are the most popular type.
We served each peanut butter blind to a panel of 64 tasters, who tasted them in a private booth, rating the taste, texture, appearance and aroma of each one.
