Instructions
- 1
Preheat the oven to 220 °C / 425 °F and lightly grease a large baking dish with 1 teaspoon of the olive oil.
- 2
In a medium saucepan, heat the milk with 500 ml (2 cups) of the chicken broth, 15 g (1 tbsp) of the butter, 1/2 teaspoon salt, and 1/4 teaspoon black pepper until nearly simmering.
- 3
Gradually whisk in the instant polenta. Cook over medium-low heat for 4 to 5 minutes, stirring, until thick and creamy. Stir in 60 g (2 oz) of the mozzarella until melted. Spread the polenta evenly in the baking dish.
- 4
Meanwhile, heat the remaining olive oil in a large skillet. Add the diced chicken, sweet paprika, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Cook for 4 to 5 minutes until the chicken is no longer pink. Remove and set aside.
- 5
In the same skillet, add the remaining butter. Sauté the onion and leek for 4 minutes until tender. Add the garlic and mushrooms and cook 5 to 6 minutes more, until the mushrooms release and evaporate their liquid.
- 6
Sprinkle the all-purpose flour over the vegetables and stir for 1 minute. Gradually pour in the remaining 250 ml (1 cup) chicken broth, stirring to avoid lumps. Cook for 2 minutes until slightly thickened.
- 7
Return the chicken to the skillet and add half of the fresh thyme. Cook 2 minutes more to blend the flavors. Taste and adjust salt if needed.
- 8
Spread the chicken, leek, and mushroom filling over the polenta base. Top with the remaining mozzarella, the Parmesan, and the rest of the fresh thyme.
- 9
Bake for 18 to 20 minutes at 220 °C / 425 °F, until the cheese is melted and golden around the edges. For more color, broil for 2 additional minutes, watching closely.
- 10
Let the bake rest for 5 minutes before serving so it sets slightly and is easier to portion.
Chef tips
For an even silkier texture, beat the polenta with a wooden spoon just before spreading it in the dish. You can also let the mushrooms brown undisturbed for the first minute to deepen their flavor.
Substitutions
You can swap the chicken breast for boneless chicken thighs. Mozzarella can be replaced with any good melting semi-firm cheese. If you do not have fresh thyme, use 1 teaspoon dried thyme.
