Full Recipe

Ingredients

• 3 eggs

• 150 ml (⅔ cup) milk or cream

• Salt, to taste

• 1 teaspoon sweet paprika

• Pepper, to taste

• 800 g (1.75 lbs) chicken fillet

• 2 cloves garlic, minced

• 2 small onions, thinly sliced

• 5 potatoes, thinly sliced into circles

• 1 red bell pepper, sliced into strips

• 2 medium tomatoes, sliced

• 1 sprig dill, chopped

• 110 g (1 cup) grated cheese (cheddar, mozzarella, or your choice)

• Olive oil or butter, for greasing the baking dish

Cooking Directions

1. Prepare the Egg Mixture
   In a large bowl, whisk together 3 eggs and 150 ml of milk or cream. Add salt, sweet paprika, and pepper. Mix well and set the mixture aside. This will serve as the creamy binding base for the casserole.

2. Prepare the Chicken
   Tenderize the chicken fillets using a meat mallet until they are even in thickness. Rub each piece with minced garlic, then season both sides with salt and pepper. Allow them to rest for a few minutes to absorb the flavors.

3. Layer the Casserole
   Preheat your oven to 180°C (356°F) and grease a baking dish with olive oil or butter. Begin assembling your casserole in layers:

   • Layer 1: Place sliced onions evenly on the bottom.

   • Layer 2: Arrange the thin potato slices over the onions, seasoning lightly with salt and pepper.

   • Layer 3: Spread the red bell pepper strips and sprinkle with chopped dill.

   • Layer 4: Lay the seasoned chicken fillets over the vegetables.

4. Add Tomatoes and Bake
   Lay the sliced tomatoes on top of the chicken fillets. Pour the prepared egg and milk mixture evenly over the entire dish. Cover the casserole with aluminum foil and bake for 60 minutes at 180°C (356°F), allowing the potatoes and chicken to become tender and juicy.

5. Add Cheese and Bake Again
   After the initial bake, remove the foil. Sprinkle most of the grated cheese generously over the top, saving a bit for later. Add another layer of tomato slices, then top with the remaining cheese. Increase the oven temperature to 210°C (410°F) and bake uncovered for another 15 minutes, or until the cheese melts beautifully and forms a golden, bubbly crust.

6. Serve
   Allow the casserole to rest for 5–10 minutes before slicing. This helps it hold its shape when served. Garnish with fresh dill or parsley and enjoy it warm as a complete meal.

Storage and Reheating Tips

Leftovers? Perfect! Store cooled casserole portions in airtight containers in the refrigerator for up to 3 days. To reheat, bake in the oven at 180°C (356°F) for 10–15 minutes, or microwave individual portions for 2–3 minutes. If freezing, wrap tightly and store for up to 2 months. Thaw overnight in the fridge before reheating. The flavors actually deepen over time, making it even tastier the next day.

Common Variations to Try

• Vegetable Boost: Add zucchini, broccoli, or spinach for extra color and nutrients.

• Creamier Version: Use half cream and half milk for a richer texture.

• Spicy Twist: Sprinkle in chili flakes or cayenne pepper for a kick.

• Cheese Lovers’ Dream: Try mixing mozzarella with cheddar or Parmesan for more flavor depth.

• Low-Carb Option: Replace the potatoes with thinly sliced cauliflower or turnips.

Pairing Recommendations

This casserole pairs beautifully with:

• A crisp green salad with lemon vinaigrette to balance the richness.

• Steamed green beans or asparagus for a light side.

• A glass of dry white wine like Chardonnay or Sauvignon Blanc.

• For something refreshing, pair with sparkling water infused with lemon and mint.
