McDonald's Hash Brown: calories and sugar by portion and age

A McDonald's Hash Brown contains 127 kcal per hash brown (55g). Boone calculates this as 6% of the 2,000 kcal adult daily reference intake. As a side or addition to a breakfast order, it is one of the lower-calorie items on the McDonald's breakfast menu. For a child aged 4 to 6 with a daily energy need of approximately 1,291 kcal, one hash brown represents 10% of their daily requirement.

Per hash brown (55g): 127 kcal, 7.4g fat (0.7g saturated), 13g carbohydrate (0.2g sugar), 1.1g protein, 0.64g salt. The sugar content is negligible at 0.2g — 1% of the daily free sugar limit for any age group. The saturated fat at 0.7g is 3-4% of daily guidelines across all age groups. The salt at 0.64g is, by Boone’s calculation, 11% of the adult daily limit and 21% for a child aged 4 to 6.

Yes — McDonald's Hash Brown is suitable for vegans. It contains no animal-derived ingredients and is free from all 14 major allergens as declared. It is one of the very few items on the core McDonald's menu that is both vegan and allergen-free. Note that McDonald's states the hash brown is cooked in the same oil as Veggie Dippers, which may not be suitable for all vegetarians depending on cross-contact concerns.

Yes. The McDonald's Hash Brown is classified by Boone as NOVA 4, ultra-processed. Despite being 83% potato, it also contains modified maize starch, dextrose and dextrin — industrial processing agents not used in home cooking. These are added to bind the potato and achieve a consistent crispy texture after frying. The NOVA 4 classification reflects the industrial formulation rather than indicating it is unsafe to eat.

McDonald's Hash Brown contains none of the 14 major allergens as declared on the McDonald's UK allergen information. This makes it one of the very few McDonald's items suitable for people with multiple food allergies. However McDonald's prepares food in kitchens where all 14 major allergens are present and cross-contamination cannot be guaranteed for any item, including the hash brown.

A McDonald's Hash Brown contains 0.2g of sugar per hash brown — negligible at 1% of the daily free sugar limit for any age group. The sugar comes from natural potato sugars rather than any added ingredient. Hash brown is one of the lowest-sugar items on the entire McDonald's menu and does not contribute meaningfully to daily free sugar intake.

A McDonald's Hash Brown contains potato (83%), rapeseed oil, modified maize starch, rice flour, dextrose, salt, pepper and dextrin. The modified maize starch and dextrin are industrial binding agents that help the hash brown hold its shape during frying. The rice flour contributes to the crispy coating. Despite containing no major allergens, the modified starch and dextrose classify it as NOVA 4.

A McDonald's Hash Brown contains 0.64g of salt — by Boone’s calculation 11% of the adult daily limit of 6g and 21% of the daily limit for a child aged 4 to 6. Adding a hash brown to a McMuffin or other breakfast item stacks the salt content, so the combined total is worth considering when ordering for children.

A McDonald's Hash Brown adds 127 kcal to any breakfast order. Adding one to a Bacon and Egg McMuffin (336 kcal) takes the combined total to 463 kcal — still a moderate breakfast by most measures. However it also adds 0.64g of salt to the McMuffin's 1.4g, giving a combined 2.04g — by Boone’s calculation 68% of the daily salt limit for a child aged 4 to 6 from two breakfast items alone.

A McDonald's Hash Brown is one of the more moderate options on the McDonald's breakfast menu for children in terms of sugar and saturated fat. The main consideration is salt stacking — a hash brown adds 0.64g of salt which accumulates quickly alongside other breakfast items. It is vegan and free from all 14 declared allergens, making it suitable for many dietary requirements. The NOVA 4 classification reflects the industrial binding agents used, not a safety concern.
