Lab-grown meat gets close to conventional meat in taste, but it’s not identical yet. The gap is narrowing as companies improve their processes, and some products score well in sensory tests. But texture, fat content, and depth of flavor remain the biggest challenges separating cultivated meat from the animal-raised version.
What Taste Tests Actually Show
The first public tasting of a pure cultivated hamburger, back in 2013, set expectations low. Three tasters described the burger as “dry and a bit lacking in flavor,” with one saying the texture felt like a conventional hamburger but the meat itself tasted “like an animal-protein cake.” That was a decade ago, and the technology has come a long way since then.
More recent evaluations of cultivated chicken have shown “remarkable similarities to conventional chicken in sensory attributes, including taste.” In one study, panelists compared a hybrid cultivated chicken product to farm-raised chicken breast, rating general flavor, texture, aroma, and overall experience. Cultivated chicken tends to perform better in these comparisons than cultivated beef, partly because chicken has a milder flavor profile that’s easier to replicate. Beef, with its complex savory depth and reliance on fat marbling, presents a harder target.
Even in instrumental analysis (where machines measure flavor compounds rather than human tongues), a cultured meat sample showed similar bitterness to beef brisket, with comparable aftertaste profiles for astringency, bitterness, and umami. The cultured sample actually scored higher in umami, the savory taste most people associate with “meatiness.” It scored lower in sourness, which contributes to the tangy complexity of aged or cooked beef.
Why Fat Is the Biggest Flavor Gap
Fat is responsible for a huge share of what makes meat taste like meat. It carries aroma compounds, creates the rich mouthfeel of a juicy burger, and breaks down during cooking to produce hundreds of volatile flavor molecules. Intramuscular fat between 3% and 7.3% is generally considered the sweet spot for flavor and consumer satisfaction in conventional meat.
Growing fat cells in a lab and integrating them into muscle tissue in the right proportions is one of the hardest problems in cultivated meat production. The specific types of fatty acids matter enormously. Certain saturated and monounsaturated fats are positively associated with favorable taste and tenderness, while a high content of polyunsaturated fats often creates off-flavors. Researchers are working on tuning the lipid composition of lab-grown fat to hit those ideal ratios, which could theoretically allow cultivated meat to be optimized for taste in ways conventional meat cannot. But consistently achieving that in a commercial product is still a work in progress.
Without enough fat, or without the right kinds of fat, cultivated meat tends to taste lean and one-dimensional. That dryness noted in the very first cultured burger tasting remains a recurring theme, though newer products have improved significantly by incorporating fat cells or plant-based fats into the final product.
Texture Remains a Telltale Difference
When a journalist from MIT Technology Review tried USDA-approved cultivated chicken at a Michelin-starred restaurant in 2023, the observation that stood out wasn’t about flavor. It was about texture. The cultivated meat felt slightly softer than conventional meat, a quality the journalist noted was also common in plant-based alternatives like Impossible burgers. A hybrid product containing both cultivated and plant-based ingredients had the same issue.
This softness comes down to structure. Conventional meat is muscle tissue that spent an animal’s lifetime contracting, building fibers, and developing connective tissue. Lab-grown cells don’t experience those forces in the same way. Companies are experimenting with edible scaffolds that give cells something to grow on and organize around, mimicking the fibrous architecture of real muscle. These scaffolds need to be food-safe, hold up during cooking, and either be edible themselves or break down before the product reaches your plate. Getting the chew and bite of a steak or chicken breast, rather than something closer to a pâté, is an active engineering challenge.
How Browning and Cooking Flavor Works
A lot of meat’s most appealing flavors don’t exist in the raw product. They develop during cooking through a chemical process called the Maillard reaction, where amino acids and sugars react at high temperatures to create the browned, complex, savory flavors of a grilled steak or roasted chicken. The specific amino acids and sugars present before cooking determine what the final flavor profile tastes like.
Cultivated meat cells do contain amino acids and proteins, so the Maillard reaction can occur. But the precise mix of flavor precursors matters. In conventional meat, a sugar called ribose is a key contributor to meaty flavor during cooking, along with glucose. Whether lab-grown cells contain these sugars in the same concentrations as animal tissue depends on the growth conditions and cell types used. The potential is there, and some products brown and develop flavor reasonably well. But replicating the full spectrum of cooked-meat aromas, which can involve hundreds of individual volatile compounds, requires matching the biochemical starting ingredients closely.
One protein plays an outsized role in this process: the oxygen-carrying molecule that gives red meat its color. It participates in fat oxidation during cooking, generating many of the volatile compounds responsible for the smell of searing beef. Some companies add this protein (produced through fermentation) to their products. Research on plant-based meat has shown that adding it reduces undesirable grain and bean flavors while boosting grilled, toasty notes. Whether it can fully replicate the flavor complexity of a well-marbled conventional steak cooked over high heat is another question, but it gets products meaningfully closer.
Where Things Stand Now
The honest answer is that cultivated meat tastes more like conventional meat than any plant-based alternative, but less like it than actual animal meat. Chicken products are closer to their conventional counterparts than beef products. Processed formats like nuggets and sausages, where the original muscle structure matters less, score better than whole cuts like steaks or breasts. Products that blend cultivated cells with plant-based ingredients or conventional meat (hybrid products) are currently the most commercially viable path to a familiar eating experience.
The flavor gap is primarily driven by three factors: insufficient fat integration, simplified texture from cells that haven’t developed the way animal muscle does, and an incomplete set of the hundreds of flavor precursors that create cooked-meat complexity. Each of these is being actively addressed through fat-cell cultivation, scaffold engineering, and biochemical optimization of growth conditions. The trajectory over the past decade, from “animal-protein cake” to products served at Michelin-starred restaurants, suggests the gap will continue to shrink. But “tastes the same” is not where the technology is today.
