Ingredients

• 1.2 kg (2.6 lb) potatoes, thinly sliced: We recommend using a mandoline for perfectly even slices, about 1/8 inch thick. Yukon Gold or Russet potatoes work beautifully – Yukon Golds offer a naturally buttery flavor, while Russets get extra crispy.
• 250 ml (1 cup) heavy cream: The heavy cream is essential for creating a luscious, creamy texture throughout the roast. It helps to bind the potatoes together and adds a richness that’s simply divine.
• 200 g (7 oz) shredded mozzarella cheese: Mozzarella provides a wonderfully gooey and melty layer. Choose low-moisture mozzarella to prevent the roast from becoming soggy.
• 50 g (1.75 oz) grated Parmesan cheese: Parmesan adds a salty, umami-rich flavor and contributes to the beautifully golden and crispy crust. Freshly grated Parmesan is always best!
• 30 g (2 tbsp) unsalted butter, melted: Melted butter brushed over the potatoes and dotted on top creates a glossy finish and enhances the overall flavor.
• 2 tbsp (30 ml) olive oil: Olive oil helps to coat the potato slices, ensuring they crisp up beautifully in the oven. Extra virgin olive oil adds a lovely fruity note.
• 2 cloves garlic, minced: Minced garlic infuses the roast with a subtle aromatic flavor. Don’t be afraid to add a little more if you’re a garlic lover!
• 1 tsp (5 g) smoked paprika: Smoked paprika adds a delicate smoky flavor that complements the potatoes and herbs.
• 1 tsp (5 g) fresh thyme leaves: Fresh thyme provides a classic herbaceous flavor that pairs perfectly with potatoes and cheese.
• 1 tsp (5 g) fresh rosemary, minced: Rosemary adds a fragrant, piney note that elevates the overall flavor profile.
• 1 tsp (5 g) lemon zest: Lemon zest brightens up the dish and adds a refreshing citrusy aroma.
• Salt and freshly ground black pepper to taste: Seasoning is key! Don’t be shy with the salt and pepper – it brings out the flavors of all the other ingredients.
• 1 tbsp (15 ml) herb‑infused oil (e.g., basil‑olive oil): A drizzle of herb-infused oil adds a final touch of flavor and visual appeal.
• 2 tbsp (15 g) chopped fresh chives: Fresh chives provide a mild oniony flavor and a pop of green color.
• 1 tbsp (10 g) pomegranate arils: Pomegranate arils add a beautiful burst of color and a slightly tart flavor that balances the richness of the roast.

Substitutions

Don’t have all the ingredients on hand? Here are a few easy substitutions:

• Mozzarella: You can substitute with provolone or Monterey Jack cheese.
• Parmesan: Pecorino Romano is a great alternative.
• Heavy Cream: Half-and-half can be used, but the roast won’t be as rich.
• Fresh Herbs: If you don’t have fresh herbs, you can use dried herbs, but use about 1/3 the amount.

Optional (plan-ahead): If you’re shopping for the week, I put this into a 4-Week Meal Plan + Grocery Lists so dinner’s already decided before your day gets busy.

Step-by-Step Instructions for the Perfect Crispy Potato Roast

1. Preheat and Prepare the Baking Dish: Begin by preheating your oven to 200°C (390°F). This ensures even cooking and optimal crisping. Place a large 9×13-inch (23×33 cm) baking dish on the middle rack. Brushing the bottom with half of the melted butter and 1 tablespoon of olive oil is crucial. This creates a non-stick barrier and contributes to the initial crisping of the potatoes.
2. Season the Potato Slices: In a large bowl, gently toss the thinly sliced potatoes with the remaining olive oil, salt, pepper, and smoked paprika. Ensure each slice is evenly coated with the seasoning. This step is vital for flavor distribution and achieving that beautiful, all-over color. Don’t overcrowd the bowl; work in batches if necessary.
3. Layer the Potatoes: Begin building your roast in the prepared baking dish. Arrange the first layer of potato slices, overlapping them slightly. This overlapping creates more surface area for crisping. Sprinkle half of the minced garlic, thyme, rosemary, and lemon zest over the potatoes. Drizzle with 2 tablespoons of heavy cream and dot with a few butter droplets.
4. Repeat the Layers: Continue layering the potatoes, seasonings, cream, and butter droplets until all the potatoes are used, ending with a final layer of potatoes. This layering technique ensures that every slice benefits from the rich flavors and creamy texture.
5. Top with Cheese and Butter: Pour the remaining heavy cream over the final potato layer. Generously sprinkle with the shredded mozzarella and grated Parmesan cheese. Dot the top with the remaining melted butter. The combination of cheeses will create a golden, bubbly, and irresistibly crispy crust.
6. Initial Bake (Covered): Cover the dish tightly with aluminum foil, ensuring the shiny side is facing down. This traps steam, which helps to cook the potatoes through and prevents the top from burning before the inside is tender. Bake for 35 minutes.
7. Final Bake (Uncovered): Carefully remove the aluminum foil. Baste the surface of the roast with any accumulated juices in the dish. This adds extra flavor and moisture. Return the dish to the oven and bake uncovered for 20-25 minutes, or until the cheese is bubbling, golden brown, and the edges of the potatoes are beautifully crisp.
8. Rest and Serve: Allow the potato roast to rest in the dish for 10 minutes before serving. This resting period allows the steam to finish cooking the center of the potatoes and makes slicing much cleaner. Run a thin knife around the edges of the roast to loosen it. Cut into wedges and transfer to plates.
9. Garnish and Enjoy: Drizzle each serving with a thin zig-zag of herb-infused oil. Scatter with chopped fresh chives and pomegranate arils for a pop of color and freshness. Serve immediately and enjoy!

Why Thinly Sliced Potatoes are Key

The secret to a truly crispy potato roast lies in the thinness of the potato slices. Thin slices maximize surface area, allowing for greater caramelization and crisping during baking. They also cook more evenly and absorb the flavors of the cream, cheese, and herbs more effectively. Using a mandoline (carefully!) is the easiest way to achieve consistent, paper-thin slices.

Choosing the Right Potatoes

While you can use various potato types, Yukon Gold or Russet potatoes work best for this recipe. Yukon Golds offer a naturally buttery flavor and creamy texture, while Russets provide a fluffier interior and excellent crisping potential. Avoid waxy potatoes like red potatoes, as they don’t crisp up as well.

The Science of the Foil: Steaming vs. Roasting

The two-stage baking process – covered with foil followed by uncovered roasting – is crucial for achieving the perfect texture. Covering the dish initially creates a steamy environment, ensuring the potatoes cook through without drying out. Removing the foil in the final stage allows the heat to directly crisp the top layer of potatoes and melt the cheese into a golden-brown perfection.

Flavor Variations and Additions

Feel free to customize this recipe to your liking! Consider adding different cheeses like Gruyère or Fontina for a more complex flavor. You could also incorporate other vegetables, such as thinly sliced onions or leeks, between the potato layers. For a spicy kick, add a pinch of cayenne pepper to the seasoning blend.

Frequently Asked Questions (FAQ)

• Can I make this ahead of time? You can assemble the roast up to 24 hours in advance and store it covered in the refrigerator. Add about 10-15 minutes to the baking time.
• What if I don’t have herb-infused oil? Regular olive oil works just fine! You can also infuse your own by adding fresh herbs to olive oil and letting it sit for a few days.
• Can I use different herbs? Absolutely! Rosemary and thyme are classic choices, but feel free to experiment with other herbs like oregano, sage, or parsley.

This Crispy Potato Roast is a show-stopping side dish that’s sure to impress. The combination of creamy potatoes, melted cheese, and fragrant herbs is simply irresistible. Don’t forget to save this recipe to Pinterest for later!
