McDonald's UK Bets on Burger Craft to Make the Nation Go Mmm
McDonald's UK launched 'A Little More Mmm' in April 2024 — a multi-channel food campaign created by Leo Burnett UK celebrating the first-ever recipe improvements to the brand's three most iconic beef burgers: the Big Mac, the Quarter Pounder with Cheese, and the Double Cheeseburger, across the United Kingdom and Republic of Ireland.
The campaign marks a genuine first in the brand's history. For the first time, McDonald's altered the recipes of its classic burgers, searing 100% British and Irish beef patties for juicier results, grilling onions directly on the grill for deeper flavour in the Big Mac and Double Cheeseburger, introducing toastier buns, serving at higher temperatures, and using meltier cheese. The creative challenge was not simply to announce these changes, but to capture something harder to verbalise: the feeling that a familiar product is, somehow, just better.
'A Little More Mmm' answers that challenge by leaning into the inarticulate. The campaign's central insight is that genuine sensory improvement resists easy description. The launch film follows three friends attempting to explain why McDonald's burgers taste noticeably more delicious, cycling through language that repeatedly falls short, until one of them abandons words entirely and breaks into an operatic tribute to the new taste experience. The absurdity is deliberate and warm, and the single syllable 'Mmm' does the communicative work that no product claim could.
Media planning and buying was handled by OMD UK. The campaign ran across television, cinema, out-of-home, press, social, radio, and digital channels — covering every major consumer touchpoint. Out-of-home placements included high-profile takeovers at Outernet London and Waterloo station, as reported by Creative Salon. Press takeovers and social stickers extended the concept further. The Clapboard Score for this campaign is 69 out of 100.
McDonald's UK operates in one of Europe's most competitive quick-service restaurant environments. According to IGD, the UK food-to-go market was valued at £23.4 billion in 2024, with the QSR segment reaching £7.2 billion, up from £5.8 billion in 2019, representing a compound annual growth rate of approximately 4.5 per cent. That growth has intensified competition across the board.
McDonald's UK holds the largest footprint among branded burger operators in the United Kingdom, with approximately 1,400 locations in 2024, according to ScrapeHero. Against this scale, competitors press hard on quality perception. Burger King UK competes directly on burger credentials, frequently positioning its flame-grilled process as a point of superiority. Greggs, while not a direct burger rival, is the largest UK chain by unit count at approximately 2,300 establishments in 2024, according to ScrapeHero, and commands a significant share of everyday food-to-go occasions that overlap with McDonald's lunchtime and commuter trade.
The strategic rationale behind 'A Little More Mmm' was therefore grounded in a real product development moment rather than manufactured positioning. By anchoring the campaign to tangible, verifiable improvements — provenance of British and Irish beef, specific cooking methods, serving temperature — Leo Burnett UK gave McDonald's UK a defensible and newsworthy claim. This marks a shift in emphasis from McDonald's UK's previous major campaigns, which had leaned more heavily on occasion and emotional territory, as noted by coverage in Creative Salon. The 2024 campaign redirects attention to food craft itself, using quality provenance as the foundation for consumer trust rather than relying on the brand's inherited familiarity alone. Matt Reischauer, Marketing Director at McDonald's UK and Ireland, publicly endorsed the campaign as a celebration of a genuinely historic product moment, as reported by Creative Salon.
Leo Burnett UK built the creative execution around a single, productively frustrating idea: that the improvement to McDonald's burgers is real but almost impossible to name. The launch film stages that frustration literally. Three friends eat upgraded burgers, grope for vocabulary, fail, and then one erupts into opera. The moment is comic, but it earns its comedy by being emotionally true — anyone who has tasted something unexpectedly good and reached for words knows the experience the film is mining.
Production credits for 'A Little More Mmm' include Andrew Long and James Millers, Executive Creative Directors at Leo Burnett UK, who framed the campaign's ambition directly. As quoted in Creative Salon on 17 April 2024, they stated: 'The iconic Big Mac, Quarter Pounder and Cheeseburger are being updated for the first time in history and we're celebrating the moment in true populist style. With work stretching across every single media channel, there really is only one word to describe this huge, integrated campaign… Mmm.' That framing — 'true populist style' — is a useful guide to the creative register. The film is broad without being shallow, accessible without being condescending.
Creative Salon also noted the campaign's use of a Snapchat lens distortion effect as a digital extension, creating a participatory social layer that invited audiences to embody the 'Mmm' reaction themselves. This demonstrates how the core concept was engineered from the outset to travel across formats. The out-of-home executions at Outernet London and Waterloo station, as reported by Creative Salon, gave the campaign physical scale in high-footfall urban environments. The operatic device also proved adaptable across radio, where the absence of visuals forced the sound design to carry full tonal weight — a discipline that sharpens rather than dilutes the creative idea.
The launch film for 'A Little More Mmm' exceeded 100,000 views, as documented by Clapboard's own archive records. That figure reflects organic and earned traction for a piece of branded content in a category where consumer attention is hard to hold. The campaign was featured as Creative Salon's Work of the Week on 18 April 2024, the day after launch, indicating strong industry reception in the United Kingdom. Ads of the World recorded the campaign on 19 April 2024, further confirming its reach into the global creative community, as noted by Ads of the World's published record.
No independently verified sales uplift figures or brand tracking data for 'A Little More Mmm' are publicly available. Structurally, however, the campaign was positioned to drive both short-term traffic and longer-term quality perception. The multi-channel deployment across TV, cinema, out-of-home, press, social, radio, and digital — with media handled by OMD UK — ensured that the campaign achieved broad reach across the United Kingdom simultaneously at launch. High-impact out-of-home placements at Outernet London and Waterloo station concentrated visibility in urban centres where competitor pressure is greatest.
The creative device itself — reducing the campaign's entire value proposition to a single, inarticulate syllable — is structurally sound as a recall mechanism. 'Mmm' is distinctive, phonetically simple, and product-linked in a way that generic brand slogans are not. Coverage from afaqs and The Drum, both of which reproduced the executive creative directors' launch statements, indicates the campaign generated meaningful trade press attention beyond the UK market.
McDonald's UK 'A Little More Mmm' celebrates the first-ever recipe improvements to the Big Mac, Quarter Pounder with Cheese, and Double Cheeseburger. Created by Leo Burnett UK in April 2024, the campaign captures how the upgraded burgers — made with seared British and Irish beef, grilled onions, toastier buns, and meltier cheese — taste better in a way that defies easy description.

Creative Salon named 'A Little More Mmm' its Work of the Week on 18 April 2024, the day after the campaign's UK launch. Ads of the World also recorded the campaign on 19 April 2024.

According to coverage in Creative Salon, 'A Little More Mmm' shifted McDonald's UK's advertising emphasis toward tangible food-quality improvements and ingredient provenance, specifically 100% British and Irish beef. This represents a strategic departure from occasion-led and emotionally driven campaigns toward product-truth advertising, anchored in a genuine and historically unprecedented recipe change to the brand's most iconic burgers.
