Ingredients

  • 1.6 pounds (750 g) chicken breast fillet, cut into medium-sized pieces
  • 2 tablespoons (30 ml) olive oil
  • 2 tablespoons (30 g) butter
  • Salt to taste
  • Ground black pepper to taste
  • 1/2 teaspoon paprika powder
  • 1/2 teaspoon garlic powder
  • 1 large onion, sliced into half-rings
  • 2-3 cloves garlic, minced
  • 14.1 oz (400 g) potatoes, thinly sliced
  • 7 oz (200 g) sour cream
  • 2 large eggs
  • 5.2 oz (150 g) mozzarella cheese, grated
  • 2.1 oz (60 g) sour cream
  • 1/2 tablespoon grainy mustard
  • 1 tablespoon Sriracha sauce
  • 2.8 oz (80 g) pickled cucumbers, chopped
  • 2-3 spring onions, chopped
  • Fresh parsley for garnish

Ingredient Notes

The use of chicken breast fillet ensures a lean and healthy protein base, while the sour cream adds richness to the sauce. If you’re short on sour cream, Greek yogurt works as a great substitute. Feel free to mix in seasonal vegetables, like spinach or bell peppers, to enhance the dish.

Kitchen Tools Needed

  • Large frying pan
  • Casserole dish
  • Mixing bowl
  • Wooden spoon or spatula
  • Grater

Step-by-Step Instructions

  1. In a large frying pan, heat the olive oil and butter over medium heat.
  2. Add the chicken breast pieces and fry until golden brown, about 6-8 minutes. Season with salt, pepper, paprika, and garlic powder. Cook for an additional 1-2 minutes, then remove and set aside.
  3. In the same pan, sauté the sliced onion and minced garlic until golden brown, about 5 minutes.
  4. Add the thinly sliced potatoes to the pan and fry for about 10 minutes, stirring occasionally, until they soften. Season with salt and pepper.
  5. Transfer the sautéed potatoes to a casserole dish, layering them at the bottom, and then spread the cooked chicken on top.
  6. In a mixing bowl, combine 7 oz (200 g) sour cream, eggs, salt, and pepper. Pour this mixture over the chicken.
  7. Grate the mozzarella over the top of the casserole.
  8. Preheat the oven to 200°C (392°F) and bake for 30-40 minutes, or until the top is golden and bubbling.
  9. For a quick sauce, mix the additional 2.1 oz (60 g) sour cream, grainy mustard, Sriracha sauce, chopped pickled cucumbers, spring onions, salt, and pepper in a bowl.
  10. Once the casserole is out of the oven, let it rest for a few minutes before serving. Garnish with fresh parsley.

Pro Tips

  • Let the casserole rest for about 10 minutes after baking to make slicing easier.
  • You can prepare the chicken and vegetables in advance; simply assemble and bake when you’re ready to eat.
  • Adjust the amount of Sriracha to suit your heat preference—feel free to omit it for a milder taste.

Common Mistakes

  • Overcooking the chicken can make it dry; aim for just golden brown before removing it from the pan.
  • Not seasoning the layers separately can lead to blandness; ensure you season each component as you go.
  • Slicing the potatoes too thick can result in them not cooking through; keep them thin for even cooking.

Variations

  • Swap out chicken for ground turkey or leftover rotisserie chicken for a quicker option.
  • Incorporate different cheese varieties like cheddar or pepper jack for added flavor.
  • Add steamed broccoli or peas to the casserole for extra veggies.

Serving Suggestions

This casserole pairs beautifully with a simple side salad or steamed vegetables. You can also serve it with crusty bread to soak up the creamy sauce.

Storage Instructions

Store any leftovers in an airtight container in the refrigerator for up to 3 days.

Reheating Tips

Reheat the casserole in the oven at 180°C (350°F) for about 20 minutes or until warmed through. Microwave reheating is also an option; just ensure to cover it loosely to avoid drying out.
