Egg McMuffin vs. Sausage McMuffin: Which McDonald’s Breakfast Sandwich Has More Protein?

For McDonald’s customers trying to get more protein at breakfast, two of the chain’s simplest sandwiches may look like close competitors. The Egg McMuffin and Sausage McMuffin both come on a toasted English muffin and include American cheese, but their protein totals differ.

The Egg McMuffin comes out ahead.

McDonald’s says the Egg McMuffin provides 17 grams of protein. Current U.S. nutrition information lists the Sausage McMuffin at 14 grams. That gives the Egg McMuffin a 3-gram advantage for diners choosing strictly between the two.

The difference matters because the Sausage McMuffin includes a substantial pork sausage patty, while the Egg McMuffin pairs an egg with Canadian bacon. Despite the Sausage McMuffin’s meatier appearance, the Egg McMuffin’s combination produces the higher protein total.

What Comes on an Egg McMuffin?

The Egg McMuffin includes a freshly cracked Grade A egg, Canadian bacon, and American cheese on a toasted English muffin with real butter. McDonald’s currently lists the sandwich at 310 calories and describes it as an excellent source of protein.

Its 17 grams of protein also earned the sandwich a place in McDonald’s 2026 push to make higher-protein choices easier to identify. In April, the company announced protein callouts for selected menu items in its kiosks and app. The Egg McMuffin was among the examples highlighted, with McDonald’s specifically listing its 17-gram protein total.

The sandwich also has a long history at the chain.

According to McDonald’s, franchisee Herb Peterson developed the original concept in Santa Barbara, California, in 1971. Peterson was inspired by Eggs Benedict and wanted to create a breakfast item that could be eaten by hand. His version replaced hollandaise sauce with cheese and used Canadian bacon and a freshly cracked egg shaped to fit an English muffin.

The sandwich entered test markets in 1972, and McDonald’s says it completed its national rollout in 1975. The company added a broader breakfast line to its national U.S. menu in 1977.

That history makes the Egg McMuffin more than just one breakfast option among many. It helped establish the chain’s morning business and remains one of McDonald’s best-known breakfast sandwiches more than five decades later.

What Comes on a Sausage McMuffin?

The Sausage McMuffin takes a simpler approach. McDonald’s describes it as a toasted English muffin topped with a hot sausage patty and a slice of American cheese.

The current U.S. version has 400 calories and about 14 grams of protein.

That means the Sausage McMuffin has 90 more calories than the Egg McMuffin but provides 3 fewer grams of protein.

For someone whose main priority is maximizing protein between these two specific sandwiches, the numbers favor the Egg McMuffin. That does not automatically make one sandwich the better choice for every customer, since taste, total calories, fat, sodium, and other dietary considerations can also influence an order.

Still, on the narrow question of protein, the difference is straightforward.

There Is a Higher-Protein Sausage Option

Customers who prefer sausage do not have to settle for the lower protein total of the standard Sausage McMuffin.

McDonald’s also sells the Sausage McMuffin with Egg. It includes a sausage patty, American cheese, and a freshly cracked egg on a toasted English muffin. McDonald’s currently lists the sandwich at 480 calories.

Current nutrition information puts it at 20 grams of protein, which is higher than both the standard Egg McMuffin and the regular Sausage McMuffin.

That changes the ranking when you include all three sandwiches.

The Sausage McMuffin with Egg has 20 grams of protein, the Egg McMuffin has 17 grams, and the Sausage McMuffin has 14 grams.

So while the Egg McMuffin wins the head-to-head comparison against the standard Sausage McMuffin, the sausage-and-egg version takes the top spot among these three McMuffin choices.

McDonald’s Switched Its Breakfast Sandwiches to Real Butter

One detail about the Egg McMuffin has also changed over the years.

McDonald’s announced in 2015 that it was moving from liquid margarine to real butter on English muffins, biscuits, and bagels used for breakfast. The company specifically cited the Egg McMuffin as part of that change.

Today, McDonald’s U.S. product page says the Egg McMuffin is served on a toasted English muffin with real butter. The Sausage McMuffin product page also describes its English muffin as freshly toasted.

For customers comparing menu items closely, McDonald’s notes that nutrition values are based on standard formulations and serving sizes and that some variation can occur because of preparation methods, suppliers, regional differences, and product changes.

Breakfast Hours Can Vary by Location

Anyone planning to order a McMuffin should also keep the clock in mind.

McDonald’s says breakfast menus and hours can vary by restaurant because local operators and franchisees have discretion over service times. In the United States, customers can often order breakfast from opening time until either 10:30 a.m. or 11:00 a.m. local time.

That means no single cutoff applies to every McDonald’s restaurant. Checking the McDonald’s app or the hours for a specific location is the safest way to know whether breakfast is still being served.

The Bottom Line

Between the Egg McMuffin and the standard Sausage McMuffin, the Egg McMuffin is the higher-protein choice.

It delivers 17 grams of protein compared with 14 grams in the Sausage McMuffin. It also contains fewer calories, with McDonald’s listing the Egg McMuffin at 310 calories and the Sausage McMuffin at 400.

For sausage fans who want even more protein, the Sausage McMuffin with Egg is the strongest option of the three, providing 20 grams of protein and 480 calories.

The protein ranking is therefore clear: Sausage McMuffin with Egg first, Egg McMuffin second, and Sausage McMuffin third.

For diners focused specifically on the original two-sandwich comparison, the Egg McMuffin takes the protein crown.
