🔥 Step-by-Step Instructions

Step 1: Prepare the Bread

Start with day-old bread. This is important because slightly dry bread absorbs sauce better and gives the casserole structure.

Cut the bread into medium cubes (not too small).

Spread them on a tray and toast in the oven at 180°C (350°F) for 8–10 minutes until slightly crispy.

This step helps prevent sogginess later.

If you skip this, the casserole may become too soft.

Step 2: Cook the Chicken Mixture

If your chicken is not cooked yet:

  • Boil or bake chicken breasts
  • Season lightly with salt and pepper
  • Shred or dice

Now heat olive oil or butter in a pan.

Add:

  • Onions
  • Garlic

Cook for 2–3 minutes until soft and fragrant.

Add the chicken and spices:

  • Salt
  • Pepper
  • Paprika
  • Herbs

Stir well and cook for 5 minutes so the flavors combine.

Turn off heat and set aside.

Your kitchen should smell amazing already.

Step 3: Make the Creamy Sauce

This sauce is what makes everything rich and soft inside.

In a saucepan:

Melt butter → add flour → whisk for 1 minute

(This makes a roux, which thickens the sauce)

Slowly pour in:

  • Milk
  • Cream
  • Chicken broth

Whisk continuously to avoid lumps.

Cook until slightly thick.

Turn off heat and add:

  • Eggs (whisked)
  • Half the cheese

Mix well.

Taste and adjust salt.

The sauce should be creamy, smooth, and flavorful.

Step 4: Combine Everything

In a large bowl combine:

  • Toasted bread cubes
  • Chicken mixture
  • Optional vegetables
  • Half the cheese

Pour the creamy sauce over everything.

Gently mix until all the bread absorbs the sauce.

Let it sit for 3–5 minutes.

This resting time allows the bread to soak up flavor.

Step 5: Assemble the Casserole

Grease your baking dish with butter or oil.

Pour the mixture into the dish and spread evenly.

Top with:

  • Remaining cheese
  • Extra bread cubes (for crunch)
  • Sprinkle of paprika
  • Parmesan (optional)

This top layer creates that crispy golden crust you see in the picture.

Step 6: Bake

Bake at:

180°C (350°F) for 30–40 minutes

Until:

  • Top is golden brown
  • Cheese is melted
  • Edges are bubbling
  • Inside is set but still soft

If you want extra crispiness, broil for 2–3 minutes at the end.

Watch carefully so it doesn’t burn.

Step 7: Rest and Serve

Let the casserole rest for 10 minutes before cutting.

This helps it hold its shape.

Cut into squares and serve warm.

The texture should be:

Crunchy top

Soft creamy middle

Juicy chicken

Melty cheese

Pure comfort.

🔥 Pro Tips for Best Results

⭐ Use stale bread

Fresh bread becomes soggy. Slightly dry bread works best.

⭐ Don’t skip toasting

Toasting improves texture and flavor.

⭐ Add vegetables

They add freshness and color.

⭐ Let it rest

Cutting too early makes it fall apart.

⭐ Cheese matters

Mix mozzarella for stretch + cheddar for flavor.
