It sounds like something a bodybuilder would drink for extra protein. But it’s far more delicious—and purposeful—than it sounds. In fact, brewing what’s known as Swedish egg coffee will result in a spectacularly smooth and mellow cup of joe. Here’s why
What Is Swedish Egg Coffee?
Swedish egg coffee is a method of using eggs to brew a large batch of deliciously smooth coffee. It’s also referred to as Norwegian egg coffee, Scandinavian egg coffee, or just egg coffee.
According to Danish coffee expert Asser Christensen, “Swedish egg coffee was brought to the U.S. by Scandinavian settlers, and it’s still popular in certain states today.” It’s also known as “church basement coffee” because it is often served at church gatherings for Scandinavian Americans in the Midwest.

To make it, all you need to do is crack an entire egg (yolk, white, and shell) into your coffee grounds, creating a potting soil–like texture, before adding it to boiling water, simmering the mixture, and pouring off your coffee. You don’t need to strain the resulting coffee—the egg binds the grounds so completely that you can simply scoop off the mixture that floats to the top.
The staying power of this technique in the fringes of American coffee culture is surprising to Christensen. “It’s an interesting trend to observe,” he says. “This type of coffee has been out of fashion for almost a century in Denmark, Sweden, and Norway.”
So how did it come about, then? “Modern coffee makers had not yet been invented [in the late 1800s], so people attempted many different things to get a delicious and clean cup,” Christensen said. “In Norway, where there is a robust tradition for cowboy coffee, dried fish skin was used instead of egg.”
But given just how smooth Swedish egg coffee is, it may be ready for a comeback.
Much like assessing the value of a brilliant diamond, clarity is important for good coffee. By combining the grounds with raw egg, the mixture separates more easily from the boiling water, ensuring that no bitter coffee grounds are left floating in the end product.
But the reasons behind the egg making a better cup of coffee extend even further than that, and for this part, we’re going to have put on our science goggles.
