First, I warmed the skillet and coated the chicken breasts with the Cajun seasoning, smoked paprika, garlic powder, onion powder and salt. Then I seared the chicken in olive oil until golden on both sides — this creates flavour and helps the bake hold together. Once browned, I set the chicken aside for the sauce stage.
In the same skillet, I added onion, bell peppers and garlic, cooking until the vegetables softened and became fragrant. Then I stirred in the chicken broth and heavy cream, followed by the cream cheese and dried thyme. The mixture simmered gently until smooth and slightly thickened.
Next I placed the browned chicken into the baking dish, poured the creamy sauce over it, then sprinkled the Monterey Jack and Parmesan cheese on top. The dish went into a preheated oven (around 180 °C/350 °F) for about 20-25 minutes, until the cheese melted, bubbled and turned golden. I garnished with fresh parsley and served it hot.
