Ingredients You’ll Need

For the Potato Rösti Base

• 800 g potatoes (waxy variety like Yukon Gold), peeled and grated
• 1 tsp salt
• 0.5 tsp black pepper (freshly ground)
• 3 tbsp unsalted butter (halal-certified), melted
• 2 tbsp vegetable oil (neutral-flavored, for frying)

For the Caramelized Leeks

• 2 large leeks (white & light green parts only), cleaned and thinly sliced
• 2 tbsp unsalted butter (halal-certified)
• 1 tbsp olive oil
• 0.5 tsp salt
• 0.25 tsp black pepper
• 1 tsp fresh thyme leaves (optional)

For the Gruyère Layer

• 150 g Gruyère cheese (halal-certified), grated

Step-by-Step Instructions

Step 1: Preparing the Potatoes

1. Grate the potatoes using a coarse grater.
2. Place the grated potatoes in a clean kitchen towel and squeeze out as much moisture as possible—this is critical for achieving a crispy texture.
3. Transfer the grated potatoes to a bowl and season with salt, pepper, and melted butter. Toss well to coat.

💡 Pro Tip: The less water in your potatoes, the crispier your rösti will be. If you have time, you can rinse the grated potatoes in cold water, then squeeze them dry to remove excess starch.

Step 2: Caramelizing the Leeks

1. In a skillet over medium-low heat, melt butter with olive oil.
2. Add the sliced leeks, season with salt and pepper, and cook slowly for 12–15 minutes, stirring occasionally, until they’re golden, soft, and sweet.
3. Stir in thyme leaves if using, then set aside.

💡 Pro Tip: Don’t rush this step—low and slow cooking allows the natural sugars in the leeks to develop, creating that sweet, caramelized flavor.

Step 3: Assembling the Rösti

1. Heat the vegetable oil in a 26 cm non-stick skillet over medium heat.
2. Spread half of the potato mixture evenly on the bottom, pressing lightly with a spatula to create a compact base.
3. Evenly spread the caramelized leeks over the potatoes, then sprinkle with all the Gruyère cheese.
4. Top with the remaining potato mixture, pressing down gently to encase the filling.

💡 Pro Tip: Pressing down gently ensures the layers stick together but don’t become too dense.

Step 4: Cooking the Rösti

1. Cook the rösti on medium heat for about 12–15 minutes, until the bottom is golden brown.
2. Place a large plate over the skillet, invert the rösti onto the plate, then slide it back into the skillet to cook the other side for another 12–15 minutes.

💡 Pro Tip: If flipping feels risky, you can cut the rösti into halves or quarters before flipping to make it easier to handle.

Step 5: Resting & Serving

1. Once both sides are golden and crisp, remove from the skillet.
2. Let the rösti rest for 5 minutes before slicing—this helps the layers set and makes cutting cleaner.
3. Serve warm, ideally with a fresh salad, sour cream, or poached eggs.

Serving Suggestions

This Crispy Potato Rösti with Gruyère & Caramelized Leeks is versatile enough to shine in different settings:

• Brunch: Pair with poached eggs, smoked salmon, or fresh avocado slices.
• Dinner Side Dish: Serve alongside roast chicken, grilled vegetables, or a hearty stew.
• Appetizer: Cut into small wedges and serve with dipping sauces like sour cream or aioli.

Tips for the Perfect Rösti

1. Choose the Right Potatoes – Waxy potatoes hold their shape better, while starchy potatoes may fall apart.
2. Don’t Skip the Squeeze – Removing moisture is key for crispness.
3. Use a Good Non-Stick Pan – Makes flipping much easier and prevents sticking.
4. Control the Heat – Too high and the outside will burn before the inside cooks; too low and it won’t crisp up.
5. Press Lightly – Enough to compact but not crush the layers.

Variations to Try

• Cheese Swap: Replace Gruyère with halal cheddar, Emmental, or mozzarella.
• Extra Vegetables: Add sautéed mushrooms, spinach, or caramelized onions to the filling.
• Vegan Option: Use vegan butter and plant-based cheese.
• Spiced Twist: Add paprika, chili flakes, or cumin to the potato mix.

Make-Ahead & Storage

• Make Ahead: Caramelize the leeks a day in advance and store them in an airtight container in the fridge.
• Storage: Store leftover rösti in the fridge for up to 3 days.
• Reheating: Reheat in a skillet to bring back crispiness—avoid microwaving if possible.
• Freezing: Wrap tightly in foil and freeze for up to 1 month; reheat from frozen in the oven at 180°C.

Why Gruyère & Leeks Work So Well Together

Gruyère cheese, with its nutty, slightly sweet flavor, melts beautifully, coating the leeks in a creamy richness. Leeks, when caramelized, offer a natural sweetness that complements the savory potatoes, creating a harmonious balance. This pairing is classic in French and Swiss cooking, making it a natural fit for this rösti.
