This week's taste test led me down an untrodden path, as I gave cornflake brands other than Kellogg's a chance — the winner completely surprised me and is much cheaper.08:21, 02 Jul 2026I have consumed many a bowl of cornflakes throughout my life and I must confess - each and every single one of those bowls has been Kellogg's.‌For most of us, it's almost been an unspoken rule that if cornflakes are to be purchased, they will be Kellogg's. I've never even considered buying another brand when it comes to this trusty breakfast staple. Until now, that is.‌This week's taste test led me down an untrodden path, at least for me, wherein I tried every major UK supermarket's own brand cornflakes in a bid to find a cheaper, equally delicious, and nutritious alternative to Kellogg's. I managed to succeed in my endeavour.‌The brands I tested were Kellogg's, Tesco, Sainsbury's, Waitrose, M&S, Morrisons, and Asda. The judging criteria was simple - flavour, crunchiness and value for money.Kellogg'sKicking off with Kellogg's, one bite instantly transported me back to my childhood - it's the flavour and taste we've all grown up with. Kellogg's' cornflakes were crunchy and delicious, with a distinct flavour that belongs only to this brand and can't be replicated.‌It was also definitely the sweetest-tasting of the competitors, which I personally don't mind, but I appreciate many others wouldn't prefer. Surprisingly, it was the box with the least amount of calories, clocking in 378kcal per 100g compared to all the other brands which were all 380kcal and above. However, at £2 for a 250g box, its value for money is where this box of delicious breakfast goodness lost out.Rating: 4/5‌WaitroseWaitrose's own brand cornflakes had a very distinct flavour of their own. Whereas most other supermarket labels' cornflakes had fairly basic-tasting flavours, there was something about Waitrose's offering that was different.Compared to the crunchiness of some of the other brands on this list, Waitrose's cornflakes were slightly lacking in that extra toasty crunch for me, however they felt like a perfectly acceptable alternative to Kellogg's. At £1 for a 500g box, the value for money was also spot on.Rating: 3/5‌M&S - 1 ingredient cornflakesMarks and Spencer's newest range of cornflakes prides itself on having just one ingredient - corn. This was the alternative I went for, as the regular M&S cornflakes weren't available in the stores I visited at the time. Coincidentally, this was the brand that absolutely shocked me and blew my mind.M&S's 'healthier' cornflakes look more like chips than cornflakes, and owing to the 'one ingredient' they are made of, they also tasted wildly different to anything else I tried for this taste test. Their flavour and texture was like a puffcorn, while their shape resembled a chip. And though they tasted decent enough, for me, it was just too much of a departure from traditional cornflakes to truly consider this as an alternative to Kellogg's. At £2.65 for 325g, it was also a punchy buy.Rating: 1.5/5‌MorrisonsMorrisons' own-brand cornflakes were the crunchiest of the lot and they weren't sweet at all. In fact, they leaned a bit towards a darker, more bitter flavour profile. They tasted pretty damn good though, and I would happily take them as an alternative to Kellogg's. At £1.90 for 500g, they were also more economical than Kellogg's, yet still on the pricier side as compared to the other options.Rating: 4/5‌TescoAnother excellent alternative to Kellogg's, Tesco's own brand cornflakes were the second crunchiest of the lot, and had a slightly distinct flavour of their own which was quite pleasant to munch and slurp on. Tesco's own-brand cornflakes were also the most reminiscent of Kellogg's, flavour-wise.At 95p for 500g, they also happened to be the most affordable and economical of all the brands.Rating: 4/5 (with a slight added edge for the price)‌Sainsbury'sSainsbury's cornflakes were pretty much the thinnest and least crunchiest of the lot for me, with their flavour tasting slightly more artificial than the other brands barring one. They also just felt a little less wholesome and nutritious when compared to the others, owing to the artificial-ish flavour. At £1.15 for 500g, they were alright when it came to value for money.Rating: 2.5/5‌AsdaI wasn't a big fan of Asda's own brand of cornflakes. The flakes themselves felt like they had no flavour at all, but more than that, they just didn't taste very cornflakey, instead feeling extra bland with a very thin texture. Compared to the other contenders on this list, I wasn't left feeling all too impressed. Also costing £1.15 for 500g, these were just okay when it came to value for money.Rating: 2/5VerdictFor me, it was a tie for this taste test, with the joint winners being Tesco and Morrisons, with Tesco coming out slightly on top for its affordable price. Asda came in last place, with Sainsbury's second to last. The M&S cornflakes were just wild, while Waitrose was very middle of the pack.Article continues belowI'd be more than happy to swap out cornflakes from Kellogg's for Tesco or Morrisons, as their own brand cornflakes are much cheaper for a larger quantity, and frankly, I wouldn't be able to tell much of a difference if I made the swap - except that my wallet would still be a little fuller.
