Pre-heat the oven to 200°.
Cut both the bell peppers and onions in rings and season the chicken thighs well with salt and pepper.
Melt the butter in the pan and cook the chicken thighs golden brown. Remove them from the pan and place them in a heat resistant dish. Add some more butter or olive oil to the pan and cook the onion and bell pepper rings until they are soft and brown. Add the pressed garlic but make sure not to burn it! Stir-fry for about 30 seconds en add the cherry tomatoes and water. Season the dish by adding the bouillon, nutmeg, thyme, rosemary and some salt and pepper. You can opt to add some fresh basil, oregano or a spring onion. The more herbs the more flavor!
Next, add the cream. Don’t add too much in one go because you don’t want the cream flavor to come out too strong.
Spread the vegetable sauce over the chicken, cover the dish with aluminum foil and place it in the oven for 30 minutes. After 30 minutes sprinkle the grated mozzarella over the dish.
Place the dish back in the oven for 10 more minutes. You can use the grill setting for the last 5 minutes. Serve immediately.
