Mercadona's €3 burger sparks debate among shoppers

The €3 Mercadona burger that rivals McDonald's

A three-euro burger bought at Mercadona and a slice of ready-to-eat pizza as a side. That was the menu that sparked the debate: the person who tried it claims that the brioche-style bun, the sauce, and the cheese are distributed with millimeter precision in every bite, and that the burger is compact, tasty, and cheap. So much so, they claim they would have paid double without blinking and regret not buying two. The barbecue pizza, however, was not convincing: the tomato does not pair well with the barbecue sauce.

From there, the issue stopped being about a burger and became a reckoning over what constitutes eating well, how much it should cost, and who has the right to decide.

What is in the Mercadona burger and why it is compared to McDonald's

The product that started it all is a burger from Mercadona's private label (the supermarket's own brand), with one- and two-patty versions—the €6 one is a double, according to reports—and an entry price of three euros. The comparison with McDonald's appears from the start: some claim it is better and cheaper than the fast-food chain, while others respond that McDonald's burgers are larger and more economical. The debate over size is recurring: some claim it is the size of a thumb and consists of two bites of processed meat with cheese and sugary bread.

The most repeated criticism concerns the meat percentage: it is mentioned that only 42% is meat, and of that percentage, only 70% is actual meat, while the rest is vegetable fiber, potato starch, and dextrose. This figure supports the argument that the product is pure visual marketing to justify a price that does not correspond to the cost of the ingredients.

On the other side, the defense relies on the value for money and the comparison with dining out. It is argued that there are restaurants serving a real burger with fries and a drink for seven euros, and that for fifteen or twenty euros, one is served a worse, slower, and sometimes cold burger. The repeated conclusion: to eat a decent burger without paying an extortionate amount, you have to go to the supermarket.

The price of the burger versus the cost of eating out

The economic core of the matter is simple to formulate but difficult to close: three euros for a supermarket burger versus the fifteen or twenty euros often charged in a restaurant for a burger that is not always up to par. Those who defend the Mercadona product present it as a decent, fast, and cheap solution; those who attack it argue that the price is not the problem, but rather the normalization of paying for processed food what used to cost a full menu.

The most frequent counterargument involves making it yourself. The suggestion is to buy beef—a 150g format for €3.50 is mentioned—and assemble the burger at home with whatever bread you choose, bringing the cost per unit to just over one euro. In other words, the private label is not cheap in absolute terms, but cheap compared to a restaurant.

The discussion also drifts toward the quality of supermarket meat in general. Some argue that the vacuum-packed beef sold at Mercadona is not bad at all and, therefore, the raw material does not have to be junk. Others point out that the fast-food chain has an added problem: the service in the establishments, which is described as inept.

The debate over junk food and judging those who consume it

The thread turns toxic when the discussion shifts from the product to the consumer. Some messages directly label the burger as junk food for people with no judgment and recommend eating high-quality food. The response is immediate: those giving lessons are reproached for boasting about their diet while being insulting, and are reminded that real food—a steak with peppers, hake romanesca, a pork chop with potatoes, or a roasted chicken leg—requires no culinary talent.

The exchange escalates with allusions to the participants' physical appearance, the fingernails of the person taking the photo, and the alleged status as a Mercadona community manager of the person defending the product. It is the classic pattern: when there are no facts, the messenger is attacked. The defense of the supermarket chain is explicit: it is argued that thanks to Mercadona, other supermarkets improved their private labels, and that the chain's own brand remains ahead in quality, presentation, and packaging.

Amidst the noise, the health argument appears. Warnings are given that a diet based on these types of products can take its toll by age forty, and it is noted that frequent consumption of processed meat carries risks. The response from those defending the product is one of compensatory effort: running six kilometers three times a week and going to the gym three other days to lift weights so they can eat whatever they want.

What about the barbecue pizza and the crispy potatoes?

The original menu did not stop at the burger. The ready-to-eat barbecue pizza received specific criticism: tomato does not go with barbecue sauce in a barbecue-flavored dish. It is the kind of detail that, in a discussion about supermarket food, serves as proof that the person opinating has actually tried the product and is not just repeating others' arguments.

The issue expanded to the crispy potatoes, which were slightly disappointing: passable as a side dish once in a while, but with a taste like dry cod fritters. The implicit conclusion is that the private label is not homogeneous: it succeeds with some products and fails with others, and the burger cannot be extrapolated to the rest of the catalog.

The burger as a cult object and the hospitality industry as a suspect

One of the most widespread ideas is that the burger has become a cult object. It is argued that they have turned a piece of meat between two buns into a fifteen or twenty-euro product, with a twenty-minute wait and the obligation to leave a positive review. In contrast, the supermarket burger solves the problem of eating decently, quickly, and cheaply.

The comparison with the free tapa (a small snack served with drinks) appears as a cultural reference: in some bars, a mini-burger is served free with coffee. This is the strongest argument against the price of the packaged product: if a bar gives it to you as a tapa, paying three euros for two bites at the supermarket is not a bargain.

The matter remains unresolved. Some say they will try it even if they expect it to be terrible; others have already paid and are repeating it. The only figure no one disputes is the one that causes the most discomfort: 42% meat. With that data on the table, the question is no longer whether it tastes good, but how much of what we pay for a burger is food and how much is marketing.
