McDonald's Cheesy Bacon Flatbread: calories and sugar by portion and age

A McDonald's Cheesy Bacon Flatbread contains 280 kcal per flatbread (130g). Boone calculates this as 14% of the 2,000 kcal adult daily reference intake. It is one of the lower-calorie hot breakfast options on the McDonald's menu, sitting between the Hash Brown and the McMuffin variants in calorie terms.

Per flatbread (130g): 280 kcal, 12g fat (5.9g saturated), 28g carbohydrate (2.4g sugar), 14g protein, 1.5g salt. The sugar at 2.4g is, by Boone’s calculation, 8% of the adult daily free sugar limit — low for a McDonald's breakfast item. The saturated fat at 5.9g is 30% of the adult daily guideline and 37% for a child aged 4 to 6. The salt at 1.5g is 25% of the adult daily limit and 50% for a child aged 4 to 6.

Yes. The back bacon in a McDonald's Cheesy Bacon Flatbread is cured with sodium nitrite, listed as a preservative in the ingredient declaration. The WHO classifies processed meat — including bacon cured with nitrites — as a Group 1 carcinogen based on evidence linking regular consumption to colorectal cancer. This classification does not mean a single serving is dangerous but is relevant context for parents making regular food choices for children.

A McDonald's Cheesy Bacon Flatbread contains 1.5g of salt — by Boone’s calculation 25% of the adult daily limit of 6g and 50% of the daily limit for a child aged 4 to 6. The bacon is the primary salt contributor, as cured bacon is inherently high in salt. Adding a hash brown to the order would bring the combined salt total to approximately 2.1g — 70% of the daily limit for a child aged 4 to 6.

Yes. It is classified by Boone as NOVA 4, ultra-processed. The flatbread contains emulsifiers. The back bacon contains dextrose and sodium nitrite. The processed cheddar cheese contains emulsifying salts. The presence of sodium nitrite in the bacon is particularly notable as a curing preservative associated with processed meat classification.

A McDonald's Cheesy Bacon Flatbread contains wheat/gluten, milk and sesame. The milk comes from the processed cheddar cheese. The sesame is in the flatbread. It does not contain egg, soya, peanuts, tree nuts, fish, shellfish, celery, mustard, lupin, molluscs or sulphites as declared allergens.

A McDonald's Cheesy Bacon Flatbread contains 2.4g of sugar — by Boone’s calculation 8% of the adult daily free sugar limit and 13% for a child aged 4 to 6. This is among the lowest sugar figures on the McDonald's breakfast menu and is not a meaningful concern. Salt and saturated fat are the more significant nutritional considerations with this item.

On calories and sugar it is a moderate option. However the salt at 1.5g uses 50% of the daily limit for a child aged 4 to 6 from a single item, and the bacon contains sodium nitrite. The WHO recommends limiting processed meat consumption for all age groups, which is particularly relevant for children. It is not suitable for vegetarians or vegans.

A McDonald's Cheesy Bacon Flatbread contains 5.9g of saturated fat — by Boone’s calculation 30% of the adult daily guideline of 20g and 37% for a child aged 4 to 6. The processed cheddar cheese is the primary saturated fat contributor. This is a moderate figure by McDonald's breakfast standards — higher than the McMuffin variants but lower than the Double McMuffin options.

The processed cheddar cheese in a McDonald's Cheesy Bacon Flatbread contains milk, emulsifying salts and added salt. It is a formulated product rather than natural block cheddar — the emulsifying salts help it melt consistently and maintain a uniform texture. This is the same processed cheese category used across the McDonald's burger range.

The Cheesy Bacon Flatbread contains 280 kcal versus 336 kcal in a Bacon and Egg McMuffin — 56 fewer calories. The flatbread has similar saturated fat at 5.9g versus 5.8g in the McMuffin. Sugar is similar at 2.4g versus 2.6g. The flatbread has slightly more salt at 1.5g versus 1.4g. The McMuffin adds egg which contributes more protein at 20g versus 14g. The two items are broadly comparable nutritionally with the McMuffin offering more protein.
