  1. Step 1: Preheat the oven to 180°C (350°F). Heat 2 tbsp olive oil in a large ovenproof skillet over medium heat. Add 2 large thinly sliced brown onions and sauté for 15 minutes, stirring frequently, until deeply caramelized and fragrant.
  2. Step 2: Add 3 minced garlic cloves and 1 tsp dried thyme to the onions and cook for 1 minute until aromatic.
  3. Step 3: Stir in 400 g diced skinless chicken thighs and cook for 5 minutes until the chicken is lightly browned but not fully cooked.
  4. Step 4: Pour in 2 cups chicken stock and bring to a simmer. Add 250 g penne pasta and stir to combine.
  5. Step 5: Dollop 150 g cream cheese over the mixture and season with 1 tsp salt and 1/2 tsp black pepper. Stir gently until the cream cheese melts and the sauce thickens slightly.
  6. Step 6: Sprinkle 1 cup grated cheddar cheese evenly over the top and transfer the skillet to the oven. Bake for 20 minutes until the cheese is golden and bubbly and the pasta is cooked through.
