Pour half of this sauce into the bottom of a gratin dish.
3️⃣ Assemble the dish
🧀 Arrange the chicken breasts on top of the sauce.
Coat them with the remaining sauce to ensure they are well coated.
Top each piece with a mixture of cheddar and mozzarella cheeses.
4️⃣ Prepare the golden breadcrumb topping
🍞 In a small bowl, combine the breadcrumbs with the melted butter and the remaining garlic powder.
Spread this mixture evenly over the cheese, pressing down lightly for a uniform crust.
5️⃣ Oven Baking
🔥 Preheat the oven to 200°C (fan-assisted).
Bake for 30 to 35 minutes, until the top is golden brown and the sauce is gently bubbling around the edges.
👉 The chicken should reach an internal temperature of 75°C to be perfectly cooked and juicy.
6️⃣ Finishing and Serving
🌿 Let it rest for 5 minutes after removing it from the oven.
Sprinkle with freshly chopped parsley.
Serve hot with a few steamed broccoli florets or homemade mashed potatoes for a complete meal.
💡 Recipe Tip
You can prepare the sauce and breadcrumbs the day before. On the day, simply assemble and bake: guaranteed time savings without sacrificing flavor.
🔄 Ingredient Substitution
No cheddar cheese on hand? Replace it with grated Comté or Swiss Gruyère, perfect for a meltingly soft and golden gratin.
🍳 Cooking tip
For an even crispier crust, place the dish under the broiler for 3 minutes at the end of cooking.
This will enhance the contrast between the golden crust and the creamy sauce underneath.
