Ingredients

To create this delightful casserole, you’ll need the following ingredients. Feel free to adjust quantities based on your preferences or the size of your baking dish!

1 large yellow onion, thinly sliced – Adds a sweet, caramelized depth to the dish.
3 medium russet potatoes, peeled and thinly sliced – The starchy backbone of the casserole, providing heartiness and texture.
2 boneless, skinless chicken breasts (approximately 600 grams), cut into bite-sized pieces – Ensures juicy, tender protein in every bite.
2 tablespoons olive oil (or vegetable oil) – Helps coat the ingredients and promotes even cooking.
1 teaspoon kosher salt, plus extra to taste – Enhances all the flavors.
1/2 teaspoon freshly ground black pepper – Adds a subtle kick.
1/2 teaspoon smoked paprika – For a smoky, warm undertone (substitute with red pepper if preferred).
1 teaspoon dried oregano – Infuses a herbaceous, Mediterranean flair.
2 large eggs – The base of the creamy sauce that binds the casserole.
200 ml heavy cream – Creates a rich, velvety texture in the sauce.
1 teaspoon curry powder – Adds a warm, aromatic complexity.
1 teaspoon dried mint – Brings a refreshing, unexpected twist.
1 medium tomato, thinly sliced – Adds freshness and a pop of color.
100 grams sharp cheddar cheese, grated – For that gooey, golden topping.
2 scallions, finely chopped – For a fresh, oniony garnish.

Equipment Needed

A large mixing bowl
A 9×13-inch baking dish (or similar size)
A whisk or fork for the sauce
A sharp knife and cutting board
Measuring cups and spoons
An oven

Step-by-Step Instructions

Preheat the Oven
Set your oven to 200°C (392°F) to ensure it’s nice and hot when your casserole is ready to bake. This temperature allows the ingredients to cook evenly while achieving that perfect golden crust.
Prepare the Ingredients
Start by peeling and thinly slicing the potatoes into rounds about 1/8-inch thick. Thin slices ensure they cook through and become tender. Next, slice the onion into thin half-moons for even distribution. Cut the chicken breasts into bite-sized chunks or thin strips to ensure they cook quickly and absorb the flavors of the spices.
Season the Base
In a large mixing bowl, combine the sliced potatoes, onions, and chicken pieces. Drizzle with 2 tablespoons of olive oil, then season generously with 1 teaspoon of kosher salt, 1/2 teaspoon of black pepper, 1/2 teaspoon of smoked paprika, and 1 teaspoon of dried oregano. Toss everything together to ensure the ingredients are evenly coated. The oil and spices will infuse the chicken and potatoes with flavor as they bake.
Assemble the Casserole
Transfer the seasoned potato, onion, and chicken mixture to a greased 9×13-inch baking dish. Spread it out evenly to ensure consistent cooking. This layer forms the hearty base of your casserole.
Make the Creamy Sauce
In a medium bowl, whisk together 2 large eggs, 200 ml of heavy cream, 1 teaspoon of curry powder, 1 teaspoon of dried mint, and an additional 1 teaspoon of salt. The eggs and cream create a custard-like texture that binds the casserole, while the curry and mint add a unique, aromatic flair. Pour this sauce evenly over the chicken and potato mixture, making sure it seeps into all the nooks and crannies.
Add the Toppings
Arrange thin slices of tomato over the top of the casserole for a burst of freshness and color. Sprinkle 100 grams of grated sharp cheddar cheese evenly over the surface for that irresistible cheesy crust. Finally, scatter chopped scallions on top for a fresh, slightly pungent finish.
Bake the Casserole
Place the baking dish in the preheated oven and bake for 40 minutes. The casserole should be bubbling, and the potatoes should be tender when pierced with a fork. To achieve a beautifully golden and crispy top, increase the oven temperature to 220°C (428°F) for an additional 10 minutes of baking. Keep an eye on it to prevent over-browning.
Rest and Serve
Remove the casserole from the oven and let it sit for 5-10 minutes. This resting period allows the flavors to meld and makes it easier to serve. Slice into portions and serve hot, garnished with extra scallions if desired.

Serving Suggestions

This chicken and potato casserole is a complete meal on its own, but you can elevate the dining experience with a few simple sides:

Green Salad: A crisp salad with mixed greens, cucumber, and a light vinaigrette balances the richness of the casserole.
Garlic Bread: Perfect for soaking up any extra creamy sauce.
Steamed Veggies: Broccoli, green beans, or carrots add color and nutrition to the plate.
Wine Pairing: A chilled glass of Sauvignon Blanc or a light Pinot Noir complements the dish’s flavors beautifully.

Tips for Success

Slice Evenly: Ensure the potatoes are sliced thinly and uniformly to cook evenly. A mandoline slicer can be a great tool for this.
Customize the Spices: Feel free to swap smoked paprika for cayenne for extra heat or add garlic powder for more depth.
Cheese Variations: Try mozzarella for a milder flavor or a mix of cheddar and parmesan for extra sharpness.
Make It Ahead: Assemble the casserole up to a day in advance, cover, and refrigerate. Add the cheese and scallions just before baking to keep them fresh.
Storage: Leftovers can be stored in an airtight container in the fridge for up to 3 days. Reheat in the oven at 180°C (350°F) for 15-20 minutes or in the microwave until warmed through.

Recipe Variations

Vegetarian Option: Replace the chicken with mushrooms, zucchini, or a mix of roasted vegetables for a meat-free version.
Spicy Kick: Add a pinch of chili flakes or a diced jalapeño to the sauce for extra heat.
Herb Swap: Substitute dried mint with fresh dill or basil for a different flavor profile.
Low-Carb Version: Swap potatoes for cauliflower florets to reduce carbs while keeping the dish hearty.

Why This Recipe Stands Out

This casserole isn’t just another weeknight meal—it’s a celebration of simple ingredients transformed into something extraordinary. The curry and mint in the sauce add an unexpected twist, while the cheddar and scallions create a picture-perfect finish. It’s versatile enough to adapt to your pantry staples, budget-friendly, and ideal for feeding a crowd. Whether you’re cooking for picky eaters or adventurous foodies, this dish delivers comfort and flavor in every bite.
