Today marks 40 years of McDonald's breakfast service. To celebrate the Egg McMuffin's 40th birthday, McDonald's Executive Chef, Dan Coudreaut, stopped by "Good Morning America" to teach us all how to make them at home. We've met Chef Coudreaut before -- he taught us all how to make our own Big Macs and once explained that he "doesn't see anything on the [McDonald's] menu that's unhealthy." We love this guy.

So, here's pretty much how Coudreaut describes the secret recipe: just make a breakfast sandwich.

We're only half kidding here. There is no "secret sauce" involved. How do they get their eggs perfectly round? They cook them in a ring. How do they get their Canadian bacon perfectly round? They cut it. With a ring. (The oohs and aahs this inspired from the crowd really concerned us.) How do they make their English muffins taste so buttery? GUYS -- they put butter on them.


So now you know how to make your own Egg McMuffin at home. Do with this information what you will. We are certainly glad to put an end to the urban legend that McDonald's has some sort of cylindrical egg-loaf that they slice their eggs from.

We are, however, concerned about the sandwich-assembling skills of the "Good Morning America" anchors. Don't quit your day jobs, guys!

  • 6: Taco Bell, $7,000,000,000

    Taco Bell's 2011 started out turbulently, with a well-publicized lawsuit surrounding the content of their beef.

  • 5: Burger King, $8,400,000,000

    Burger King hopped on the avocado band wagon last year, which was only one of many changes the chain underwent, including the <a href="http://www.huffingtonpost.com/2011/08/19/burger-king-de-thrones-king_n_931208.html" target="_hplink">dethroning of their mascot, The King</a>.

    It seemed likely that <a href="http://www.huffingtonpost.com/2012/03/19/wendys-burger-king-number-two_n_1364514.html" target="_hplink">Wendy's would dethrone Burger King to become the second biggest burger chain in the U.S.</a> -- and it turns out, they totally did.

  • 3: Starbucks, $9,750,000,000

    Starbucks closed the most locations of any of the chains in the top ten last year, shuttering 310 locations. In 2011 the chain also <a href="http://www.huffingtonpost.com/2011/01/17/starbucks-new-size-trenta-graphic_n_810083.html" target="_hplink">rolled out its insane, 31oz Trenta size</a>.

  • 2: Subway, $11,400,000,000

    Subway was recently crowned both <a href="http://www.huffingtonpost.com/2012/05/10/best-fast-food-restaurants_n_1507319.html" target="_hplink">America's favorite fast food restaurant</a> and its <a href="http://www.huffingtonpost.com/2011/03/07/worlds-largest-restaurant-chain-subway_n_832511.html" target="_hplink">biggest chain</a>. Opening 872 new locations in 2011, their total number of U.S. locations rose to 24,722, nearly beating McDonald's and Starbucks combined.

  • 1: McDonald's, $34,172,000,000

    Well, no surprise here, right? While no longer the largest fast food chain in America, McDonald's is surely the most successful -- their 2011 U.S. revenue beats Subway and Starbucks' totals combined. A recent American Consumer Satisfaction Index survey revealed that the chain is, however, <a href="http://www.huffingtonpost.com/2012/06/21/mcdonalds-low-customer-satisfaction_n_1615606.html" target="_hplink">at the bottom in terms of customer satisfaction</a>, so McDonald's may not reign forever.
