There’s something deeply satisfying about a crispy potato rosti, golden and lacy at the edges, with a runny egg on top. This dish brings Swiss tradition to your breakfast table with minimal effort.
I developed this method to ensure perfectly shredded potatoes that turn tender inside while forming a crispy crust. The egg is added just before serving, so the yolk stays rich and runny.
Each bite delivers the contrast of textures: the crunch of the rosti, the creaminess of the yolk, and the earthy flavor of the potatoes. It’s a simple dish that feels special.
Serve it hot, straight from the pan, for the best experience. This is comfort food at its finest.
Ingredients for Potato Rosti Recipe with Egg
Simple ingredients create a crispy, golden rosti with rich, runny egg yolks.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 lb | Peeled and shredded |
| Large Eggs 🥚 | 4 whole | For topping rosti |
| Unsalted Butter 🧈 | 3 tbsp | For crisping potatoes |
| Olive Oil 🫒 | 2 tbsp | Divided for frying |
| Kosher Salt 🧂 | 1 ½ tsp | Divided, adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Fresh Chives 🌿 | ¼ cup | Chopped, for garnish |
| Garlic Powder 🧄 | ½ tsp | Optional, for depth |
| Onion Powder 🧅 | ½ tsp | Optional, for depth |
| Sweet Paprika 🌶️ | ¼ tsp | For color and flavor |
The potatoes are the foundation here. Russet potatoes give you that perfect crispy exterior with a tender interior—Yukon Golds are a decent backup but have a waxier texture. Grab them from any grocery store, just make sure they’re firm and free of sprouts. For the butter, European-style has a higher fat content, which helps with browning. I always keep a few blocks on hand for cooking projects like this.
No russets? Yukon Golds work in a pinch but won’t get as crispy. Out of fresh chives? Green onions add a similar fresh bite. For extra flavor, a pinch of smoked paprika instead of sweet adds depth. The eggs are non-negotiable for that runny yolk, but if you’re making this vegan, skip the egg and maybe add a dollop of cashew cream for richness.
Shredded potatoes oxidize quickly, so keep them in cold water until ready to cook. The rosti is best served immediately but can be kept warm in a 200°F oven for up to 15 minutes. Leftovers? Not ideal, but they’ll keep in the fridge for 2 days—reheat in a skillet to crisp up.

Step-by-Step Instructions for Potato Rosti With Egg
This method ensures a crispy potato base with perfectly runny egg yolks every time.
Step 1: Prepare and Season the Potatoes
Peel the 2 lb Russet Potatoes and shred them using the large holes of a box grater. I like to work quickly here to prevent browning. Transfer the shredded potatoes to a clean kitchen towel and squeeze out as much moisture as possible—this is critical for achieving that crispy texture.
Place the dried potatoes in a large bowl and immediately toss with 1 tsp Kosher Salt, 0.5 tsp Black Pepper, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, and 0.25 tsp Sweet Paprika. The seasoning should be evenly distributed throughout.
Step 2: Form and Cook the Rosti
Heat 2 tbsp Olive Oil and 1 tbsp Unsalted Butter in a large nonstick skillet over medium heat until the butter melts and starts to foam. Add the seasoned potato mixture, pressing down firmly with a spatula to create an even layer about ½-inch thick.
Cook undisturbed for 8-10 minutes until the bottom is deep golden brown and crispy. I press down on the potatoes occasionally with the spatula to ensure even contact with the pan. You’ll know it’s ready to flip when the edges look set and the bottom releases easily from the pan.
Carefully flip the rosti using a large plate or second pan. Add the remaining 2 tbsp Unsalted Butter to the skillet and slide the rosti back in. Cook for another 8-10 minutes until equally crispy and golden on the second side.
Step 3: Add the Eggs
Once the rosti is crispy on both sides, use a spoon to create four small wells in the potato mixture. Crack each of the 4 whole Large Eggs into these wells, spacing them evenly. Sprinkle the eggs with the remaining 0.5 tsp Kosher Salt.
Cover the skillet and cook for 4-5 minutes until the egg whites are set but the yolks remain runny. The steam from the covered pan helps cook the tops of the eggs without overcooking the yolks.
Step 4: Garnish and Serve
Remove from heat and let sit for 1 minute to allow the eggs to finish setting slightly. Sprinkle with the 0.25 cup Fresh Chives, which adds a pop of color and fresh flavor that cuts through the richness.
Serve the rosti directly from the skillet, cutting it into four portions with one egg per serving. Each bite should have crispy potato edges with a creamy, runny yolk center. The contrast of textures and flavors is what makes this dish special.
Pro Tips For Making Potato Rosti Recipe With Egg
- Squeeze Out Moisture: After grating the russets, wrap them in a clean towel and twist hard—this removes excess water so your rosti gets crispy instead of soggy. I learned this the hard way after my first few attempts turned into potato pancakes.
- Hot Pan, Cold Butter: Heat the olive oil until it shimmers, then add the butter just before the potatoes—this prevents the butter from burning while giving you that rich, golden crust.
- Press Hard, Don’t Stir: Once the rosti is in the pan, press it down firmly with a spatula and resist the urge to stir. Letting it sit undisturbed for 4-5 minutes is what creates that perfect, lacey edge.
- Top With Egg Last: Crack the eggs on top only after the rosti is nearly set—about 3 minutes in—so the whites cook through without overcooking the yolks. Sounds obvious, but I’ve ruined more than one batch by adding them too early.
Make-Ahead Tips for This Recipe
Prep Ahead for Morning
Shred the 2 lb Russet Potatoes the night before and store them in cold water in the fridge. This prevents browning and saves 10 minutes in the morning. Drain and squeeze dry just before cooking. 💡
Form Rosti Patties
For even better texture, form the shredded potatoes into individual rosti patties after seasoning. Place them on a parchment-lined tray, cover, and refrigerate for up to 8 hours. This helps them hold shape when cooking.
Oven Method Option
To free up stovetop space, bake formed rosti at 400°F on a parchment-lined sheet pan for 15 minutes per side. Add eggs during the final 5 minutes of cooking. I love this hands-off approach for busy mornings.
Keep Warm Strategy
Once cooked, transfer your rosti to a wire rack in a 200°F oven. This keeps it crispy for up to 15 minutes while you fry the eggs separately. The rack allows air circulation to prevent sogginess.
Reheat Leftovers
Though best fresh, leftovers can be revived in a skillet over medium heat for 3-4 minutes per side. Add a splash of olive oil to help recapture that crispy texture. Top with a fresh egg for best results.

Russets work best for crispiness, but Yukon Golds are a good backup. They have a waxier texture, so squeeze out extra moisture for the best results.
How do I keep the rosti from falling apart when flipping?
Press the potatoes firmly into the pan and cook until the edges are set. Use a large plate to help flip it in one motion.
Can I make this without a nonstick pan?
Yes, but use extra butter or olive oil to prevent sticking. A well-seasoned cast-iron skillet works too.
What’s the best way to reheat leftovers?
Revive in a skillet over medium heat for 3-4 minutes per side with a splash of olive oil. Add a fresh egg for the best texture.
