Ingredients

• 2 eggs

• Salt, to taste

• Black pepper, to taste

• 1 tablespoon mayonnaise

• 1 tablespoon sour cream

• 100 g mozzarella cheese, shredded

• 2 cloves garlic, minced

• Vegetable oil, for cooking

• 1 red onion, thinly sliced

• 4 medium potatoes, peeled and thinly sliced

• 1 teaspoon paprika

• 1 teaspoon oregano

• Olive oil, for drizzling

• 2 chicken fillets

• 1 tablespoon butter

• 2 tomatoes, thinly sliced

• Fresh parsley, chopped, for garnish

Cooking Directions

1. Prepare the Creamy Egg Mixture
   Crack the eggs into a bowl and whisk them together with mayonnaise, sour cream, salt, and black pepper. Stir in the shredded mozzarella and minced garlic to create a creamy, cheesy mixture that will bind the potatoes.

2. Season the Potatoes
   Peel and thinly slice the potatoes. In a large bowl, toss them with paprika, oregano, salt, black pepper, and a drizzle of olive oil until evenly coated.

3. Bake the Potato Base
   Grease a baking dish with vegetable oil. Arrange the seasoned potato slices and red onion rings in layers. Pour the creamy egg-mozzarella mixture evenly over the top. Bake in a preheated oven at 180℃ (360℉) for 20–25 minutes until the potatoes are tender and lightly golden.

4. Prepare the Chicken
   While the potatoes bake, season the chicken fillets with salt and black pepper. Heat a mix of butter and vegetable oil in a skillet and lightly sear the chicken fillets for 2–3 minutes per side until golden brown (they don’t need to be fully cooked at this stage).

5. Layer Chicken and Tomatoes
   Remove the potato base from the oven. Arrange the seared chicken fillets on top of the potatoes. Place the sliced tomatoes over the chicken, overlapping slightly for coverage.

6. Final Bake
   Return the dish to the oven and bake for another 20–25 minutes at 180℃ (360℉), until the chicken is fully cooked and the tomatoes have softened into the dish.

7. Garnish and Serve
   Remove from the oven, sprinkle with fresh parsley, and let it rest for 5 minutes before serving. Slice and serve hot, enjoying all the cheesy, creamy, savory layers in every bite.

Why You’ll Love This Recipe

You’ll love this casserole because it combines everything people adore about comfort food—potatoes, cheese, chicken, and tomatoes—into one easy-bake dish. It’s creamy without being too heavy, cheesy without being greasy, and filling enough to stand on its own. Plus, it looks as good as it tastes, with beautiful layers of golden potatoes, juicy chicken, and vibrant tomatoes topped with bubbling mozzarella.

The Origins and Inspiration Behind the Dish

This dish takes inspiration from classic European baked casseroles, where layers of potatoes, meat, and vegetables are combined with creamy sauces and baked until golden. It shares similarities with French gratins and Mediterranean baked chicken dishes but takes a more accessible approach with ingredients most kitchens already have. The use of mayonnaise and sour cream is a modern twist that keeps the dish rich and creamy while avoiding the need for a complicated sauce.

Ingredient Spotlight

Potatoes form the base of this dish, offering hearty texture and starchiness. The eggs, mayonnaise, and sour cream mixture binds everything together while also providing moisture and richness. Mozzarella adds that iconic cheese pull we all love, while tomatoes bring freshness and a gentle acidity to balance the creaminess. Chicken fillets ensure the casserole has enough protein to make it a complete meal, while paprika, oregano, and garlic give it bold, savory flavors.

Storage and Reheating Tips

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and bake at 180℃ (360℉) for 15–20 minutes, or microwave individual portions until heated through. For freezing, assemble the casserole without baking, wrap tightly with plastic wrap and foil, and freeze for up to 2 months. Bake directly from frozen, adding an extra 15–20 minutes to the cooking time.

Common Variations to Try

This casserole is very adaptable. You can swap mozzarella with cheddar or gouda for a stronger cheese flavor. Add spinach or mushrooms to the layers for extra vegetables. Replace chicken with turkey breast or even thinly sliced beef for variation. For a lighter version, use Greek yogurt instead of sour cream and low-fat cheese. If you like heat, add chili flakes or cayenne pepper to the seasoning.

Pairing Recommendations

This casserole pairs beautifully with a simple green salad dressed in vinaigrette, which cuts through the richness of the cheese and potatoes. Garlic bread or crusty rolls also make a great side. For drinks, a crisp white wine such as Chardonnay or Pinot Grigio complements the creamy, cheesy layers, while a sparkling lemonade or iced tea makes a refreshing non-alcoholic pairing.

Health Benefits

While this casserole leans indulgent, it does contain a good balance of nutrients. The chicken provides lean protein, while potatoes offer potassium, fiber, and vitamin C. Tomatoes add antioxidants like lycopene, which support heart health, while parsley offers vitamins A and K. Moderating portion sizes makes it possible to enjoy this hearty dish while still staying mindful of overall nutrition.
