Preparation

1. Preheat the oven
   Set oven to 375°F (190°C). Lightly grease a 9×9 inch (23×23 cm) baking dish.

2. Soften the aromatics
   In a skillet over medium heat, melt the butter.
   Add the diced onion and cook for 4 minutes until soft.
   Add the garlic and cook 30 seconds more.

3. Make the creamy sauce
   Sprinkle the flour over the onion mixture and stir constantly for 1 minute.
   Slowly pour in the milk and chicken broth while whisking.
   Cook for 3–4 minutes until the sauce thickens.

   Stir in the salt, pepper, thyme, and smoked paprika.
   Remove from heat.

4. Combine the filling
   In a large bowl, mix:

   • shredded poultry

   • shredded tubers

   • the warm sauce

   • ¾ cup (75 g) of the shredded cheese

   Stir until evenly coated.

5. Assemble
   Spread the mixture evenly into the prepared baking dish.
   Sprinkle the remaining ¼ cup (25 g) cheese over the top.

Baking

6. Bake uncovered for 40–45 minutes
   The casserole is ready when:

   • the top is golden

   • the edges are gently bubbling

   • a knife inserted in the center meets tender tubers with no resistance

7. Rest
   Let the dish stand for 10 minutes before serving.
   This allows the sauce to settle and makes slicing easier.

8. Finish
   Sprinkle with chopped parsley if using.

Texture and Flavor Guide

• Top: lightly crisp and cheesy

• Center: creamy and cohesive, not watery

• Tubers: soft but still defined strands

• Poultry: moist and evenly distributed

Optional Exact Variations

• Add ½ cup (60 g) frozen peas or corn to the mix for color and sweetness.

• Replace half the potatoes with sweet potatoes for a gentle earthy note.

• Mix 2 tablespoons grated Parmesan into the topping for extra savoriness.

Storage and Reheating

Refrigerate leftovers in an airtight container for up to 3 days.
Reheat portions in a 350°F (175°C) oven for about 15 minutes, or microwave until hot throughout.

This casserole is the kind of meal that rewards slow baking and simple ingredients. With precise steps and balanced seasoning, it delivers a comforting, golden dish where tender poultry and soft shredded tubers come together in every warm, satisfying spoonful.
