A Festive, Gorgeous Rösti Recipe to Brighten Your Morning

The Swiss are really good at a lot of things. Cheese. Watches. Mountains. Snow. General wintery charm. And, of course, potatoes! Crispy Swiss rösti potatoes are an irresistible dish, as far as we’re concerned. They’re everything a great potato side dish should be—crisp on the outside, buttery-tender on the inside and, yes, CHEESEY! We take the rösti over the top though, by topping it with eggs, bacon (or ham) and asparagus to make for a lovely, sophisticated brunch dish that’ll wow every single guest on your list. It’s an all-in-one rösti-based casserole that’s majorly elevated from the egg-and-sausage breakfast casseroles of yore.

What is Rösti?

And what’s the difference between rösti and hash browns? Rösti potatoes are actually a lot like American hash browns! At their simplest, rösti potatoes are just grated potatoes fried or baked until crisp in butter (similar to our Corned Beef Hash recipe). We dress ours up beyond the classic, though! Taking a cue from latkes—another of our favorite potato pancake recipes—we grate onion into the mixture for a little extra punch of flavor and moisture. Our cheese-enhanced potato and onion rösti then makes a lovely, rich, crispy bed for eggs and asparagus. YUM! Breakfast is served!

How To Make This Potato Rosti Casserole

Meet your new favorite brunch recipe! Here’s how easy it is to make our potato rösti casserole recipe:

  1. Scrub and boil the potatoes with the peels on!

  2. Grate stuff! Grate the onion and wring out as much moisture from the grated onion as you can by wrapping it in a kitchen towel and squeezing it out over the sink. Grate the potatoes, too.

  3. Stir in the grated potatoes and onions with bacon or ham, gruyere, Parmesan, butter, salt, pepper, nutmeg, Greek yogurt and Dijon mustard.

  4. Spread the potato rösti mixture in a baking dish. Bake for 35 minutes, then broil for about 3 minutes.

  5. Blanch the asparagus while your potato rösti casserole bakes.

  6. Use the back of a big kitchen spoon to make 8 little indentations in the top of the casserole. Nestle the blanched asparagus into the casserole around the wells. Crack an egg into each little indentation, and dust everything with more Parmesan.

  7. Bake until the egg whites are set but the yolks are still runny, which will be about 10 more minutes. But, keep a close eye on it! Watching is the best way to nail the doneness of the eggs in this rösti recipe.

Description

Golden brown and gorgeous, topped with sunny, runny eggs and just-so asparagus, this cheesy potato rösti recipe is ready to anchor your festive brunchy gatherings.

Ingredients

  • 3 ½ pounds russet potatoes, scrubbed and halved lengthwise
  • ½ medium yellow onion
  • 1 cup crumbled bacon or chopped ham
  • 1 ½ cups shredded Gruyère cheese
  • ½ cup freshly grated Parmesan cheese
  • ¼ cup (½ stick) salted butter, melted, plus more for greasing
  • 2 teaspoons sea salt
  • ½ teaspoon freshly cracked black pepper
  • ¼ teaspoon ground nutmeg
  • 1 ¼ cup plain Greek yogurt, plus more for serving
  • 2 tablespoons Dijon mustard
  • ½ pound asparagus, 4-inch pieces
  • 8 large eggs
  • Minced fresh chives, for garnish

Method

  1. Place the potatoes in a large pot and cover with cold water by 2 inches. Bring to a boil over high heat, then reduce the heat to maintain a simmer. Cook for 10 to 12 minutes, or until the potatoes are just tender when pierced with a fork but still hold their shape. Drain and return to the pot. Let cool until the potatoes are cool enough to handle,about 15 minutes, then peel and set aside.

Turn on the broiler and cook until lightly browned and crispy on top, about 3 more minutes. Remove from the oven and reduce the temperature back to 400°F.
