- 500g chicken breast: Use fresh, boneless, and skinless chicken breasts for a lean source of protein. These will be seasoned and cooked to golden perfection for maximum flavor.
- 1 tbsp chicken seasoning: A flavorful blend of spices, such as garlic powder, paprika, and onion powder, to enhance the taste of the chicken.
- 1 onion, finely diced: Choose a medium-sized onion, either white or yellow, to add a subtle sweetness and depth to the dish.
- 3 peppers, finely diced: Use a mix of red, green, and yellow bell peppers for a colorful, sweet, and slightly crisp addition to the recipe.
- 3 tsp garlic purée (or 3 cloves, minced): Adds a rich, aromatic base. Garlic purée is convenient, but fresh minced garlic will also work beautifully.
- 300g pasta (uncooked weight): Any short pasta like penne, macaroni, or fusilli works well, as their shapes hold the creamy sauce perfectly.
- 400ml hot chicken stock: Use a good-quality chicken stock (either homemade or store-bought) to infuse the pasta with a savory flavor as it cooks.
- 600ml warm milk: Use whole milk for a rich and creamy sauce, but semi-skimmed milk can also be used if you prefer a lighter option.
- 1 tsp mustard: Adds a slight tang and depth to the creamy cheese sauce. This step can be skipped if you prefer a more classic flavor.
- 120g cheese: A mix of extra mature cheddar and mozzarella works best. Cheddar gives sharpness, while mozzarella melts beautifully for a creamy texture.
- Salt and pepper, to taste: Adjust these as needed to balance and enhance the overall flavor.
- Parsley and chili flakes (optional, for garnish): Fresh parsley adds a pop of color and freshness, while chili flakes bring a spicy kick for those who like extra heat.
