Wash the chicken breast fillets and pat dry. Season well with salt, pepper, paprika powder, and chilli salt. Heat clarified butter in a large pan over medium-high heat. Add the chopped garlic and chicken fillets, frying on all sides for 10-12 minutes until golden brown.
While the chicken is cooking, cut 6 tomatoes into slices and 2 tomatoes into small cubes. In a measuring cup, combine cremefine, cream, water, and sauce powder, stirring until smooth. Stir in the diced tomatoes.
Pour the sauce mixture into a large baking dish. Arrange the fried chicken fillets on the sauce and sprinkle with the chopped basil. Place 4 tomato slices on each fillet. Mix the Gouda and Emmentaler cheese together and sprinkle generously over the tomatoes.
Bake for 30 minutes at 160°C (320°F) using hot air convection until the chicken reaches an internal temperature of 74°C (165°F).
