Adding ground flaxseed to mince can make burgers "noticeably juicier" while boosting their nutritional profile, according to a food expert. Lily Keeling, senior recipe development manager at Green Chef, described the ingredient as "unexpected" but highly effective for achieving succulent homemade burgers.
How Flaxseed Improves Burger Texture
Keeling explained that ground flaxseed can absorb and retain several times its weight in moisture, which prevents the burger from drying out during cooking. "Flaxseed can absorb and retain several times its weight in moisture, making it perfect for creating a burger that's noticeably juicier," she said. The recommended amount is one to 1.5 tablespoons of ground flaxseed per 500g of mince, which typically yields about four burgers. Adding more than that can result in an odd taste, so sticking to the suggested quantity is important.
Nutritional Benefits and Flavour Impact
Beyond texture, flaxseed adds nutritional value, providing fibre and plant-based omega-3 fatty acids. Keeling noted that the flavour is barely noticeable when used in small amounts: "The good news is you won't end up with a burger that tastes weird or unusual. When used in small amounts, the flavour is barely noticeable." This makes it an easy addition for health-conscious cooks.
Availability and Storage Tips
Ground flaxseed is widely available in supermarkets, such as Sainsbury's, where a 200g bag costs around £2.20. It can also be added to water, porridge, yoghurt, or smoothies. However, it spoils quickly, so it should be stored in an airtight container in the fridge to maintain freshness.
