McDonald's Sausage and Egg McMuffin: calories and sugar by portion and age

A McDonald's Sausage and Egg McMuffin contains 424 kcal per McMuffin (173g). Boone calculates this as 21% of the 2,000 kcal adult daily reference intake and 33% of the daily energy need for a child aged 4 to 6. It is the highest calorie standard McMuffin variant on the core McDonald's breakfast menu.

Per McMuffin (173g): 424 kcal, 23g fat (8.2g saturated), 27g carbohydrate (3.1g sugar), 25g protein, 1.6g salt. The saturated fat at 8.2g is, by Boone’s calculation, 41% of the adult daily guideline — the highest of any McMuffin variant. The sugar at 3.1g is 10% of the adult daily free sugar limit — low. The salt at 1.6g is 27% of the adult daily limit and 53% of the daily limit for a child aged 4 to 6.

No. Unlike the bacon used in the Bacon and Egg McMuffin and Cheesy Bacon Flatbread, the pork sausage patty in a McDonald's Sausage and Egg McMuffin does not contain sodium nitrite. The sausage ingredients are pork, water, salt, spices, modified starch and flavourings — no curing agent. This means the Sausage and Egg McMuffin avoids the nitrite-related processed meat classification that applies to the bacon items, despite still being NOVA 4 from the modified starch and flavourings.

A McDonald's Sausage and Egg McMuffin contains 8.2g of saturated fat — by Boone’s calculation 41% of the adult daily guideline of 20g and 51% for a child aged 4 to 6. This is the highest saturated fat of any McMuffin variant, significantly more than the Bacon and Egg McMuffin at 5.8g and the Egg and Cheese McMuffin at 5g. The pork sausage patty is the primary driver — pork sausage is inherently higher in saturated fat than back bacon.

The Sausage and Egg McMuffin contains 424 kcal versus 336 kcal in the Bacon and Egg McMuffin — 88 more calories. Saturated fat is 8.2g versus 5.8g — 41% more. Salt is 1.6g versus 1.4g — slightly more. Sugar is similar at 3.1g versus 2.6g. Protein is higher at 25g versus 20g. The sausage version has no sodium nitrite; the bacon version does. For lower calories and lower saturated fat, the Bacon and Egg McMuffin is the more moderate choice. For no nitrites, the sausage version has the advantage.

A McDonald's Sausage and Egg McMuffin provides 25g of protein — by Boone’s calculation 50% of the adult daily protein guide of around 50g. This is the highest protein of any McMuffin variant, higher than the Bacon and Egg McMuffin at 20g and the Egg and Cheese McMuffin at 15g. The pork sausage patty is the primary protein contributor alongside the egg and processed cheese.

A McDonald's Sausage and Egg McMuffin contains wheat/gluten, milk and egg. It does not contain soya, sesame, peanuts, tree nuts, fish, shellfish, celery, mustard, lupin, molluscs or sulphites. The allergen profile is identical to the Bacon and Egg McMuffin and the Egg and Cheese McMuffin. McDonald's prepares food in kitchens where all 14 major allergens are present.

Yes. It is classified by Boone as NOVA 4, ultra-processed. The English muffin contains raising agents, emulsifiers and an acidity regulator. The pork sausage patty contains modified starch and flavourings. The processed cheese contains enzymes. The whole egg is the only minimally processed component. Despite containing no sodium nitrite, the sausage patty's modified starch and flavourings place the overall item in NOVA 4.

The saturated fat at 8.2g represents 51% of the daily guideline for a child aged 4 to 6 from a single breakfast item — the highest of any McMuffin variant. The salt at 1.6g uses 53% of the daily limit for a child aged 4 to 6. On the positive side it contains no sodium nitrite and provides 25g of protein. It is not suitable for vegetarians or vegans. For children, the Egg and Cheese McMuffin is a more moderate choice on both calories and saturated fat.

A McDonald's Sausage and Egg McMuffin contains 1.6g of salt — by Boone’s calculation 27% of the adult daily limit of 6g and 53% of the daily limit for a child aged 4 to 6. This is slightly more than the Bacon and Egg McMuffin at 1.4g and significantly more than the Egg and Cheese McMuffin at 1.1g. Adding a hash brown brings the combined salt to approximately 2.24g — 75% of the daily limit for a child aged 4 to 6.
