Before you start

Before beginning this recipe, ensure all ingredients are measured and ready for assembly. Preheat your oven to 375°F (190°C) to ensure it reaches the correct temperature by the time the dish is ready for the oven.

Slice the chicken into uniform strips to guarantee even cooking. Having a clean workspace and all necessary equipment, such as a sturdy baking dish and a reliable skillet, will make the cooking process smooth, efficient, and enjoyable from start to finish.

Ingredients at a glance (5)
  • 1 lb chicken breasts, sliced into strips
  • 2 tbsp Cajun seasoning
  • 12 oz penne pasta
  • 2 cups creamy sauce
  • 1 cup cheesy topping

Instructions

Searing and Pasta Prep

  1. Prepare the Chicken and Pasta
    Boil the penne in a large pot of salted water until al dente, then drain. Meanwhile, sear the sliced chicken in a hot skillet with the Cajun seasoning until fully browned and cooked through. Ensure the chicken reaches an internal temperature of 165°F (74°C) before removing it from the heat.
    Look for The chicken should be opaque and well-seasoned with a golden-brown sear on all sides.

    Tip Keep the chicken strips uniform in size to ensure they cook evenly in the skillet.

The chicken should be fully cooked, possessing a dark, aromatic crust from the Cajun spices. The penne must be tender but still firm to the bite, as it will absorb additional moisture from the cream sauce during the baking phase. Ensure the skillet is hot enough to achieve a proper sear, as this color is essential for the depth of flavor in the finished sauce.

Assembly and Cream Addition

  1. Combine and Sauce
    Transfer the cooked penne and seared chicken into a large baking dish. Pour the creamy sauce over the mixture, ensuring everything is well-coated. Sprinkle the cheesy topping evenly across the top to create a rich, cheesy layer that will melt perfectly during the baking process.
    Look for The cream should pool slightly at the bottom of the dish while the cheese covers the surface.
    Tip Stir the mixture gently to distribute the Cajun spices throughout the creamy sauce.

The mixture should be well-combined, with the cream evenly distributed throughout the baking dish. The cheese should form a solid, uniform layer across the top.

Check that the pasta is completely submerged in the cream to prevent any dry or hard edges during the baking process. The dish should look visually appealing, with the vibrant spices beginning to tint the cream a beautiful, warm hue.

Baking to Perfection

  1. Bake and Serve
    Place the baking dish into a preheated oven at 375°F (190°C) and bake for approximately 15 to 20 minutes. The dish is ready when the cheese is bubbly, slightly browned, and the sauce has thickened into a creamy consistency. Allow the dish to rest for 5 minutes before serving.
    Look for The edges should be bubbling vigorously and the cheese on top should look melted and slightly golden.
    Tip Watch the top closely to prevent the cheese from burning if the oven runs particularly hot.

The final dish should be bubbling vigorously around the edges, with the cheese fully melted and showing spots of golden brown. The sauce should have thickened into a rich, velvety consistency that holds the chicken and pasta together. Allow the dish to sit for at least five minutes to let the sauce stabilize, ensuring each portion holds its shape when served to the plate.

Common mistakes

Avoid overcooking the penne during the initial boiling step, as the pasta will continue to cook slightly while in the oven. If the pasta is too soft before baking, it may lose its structure and become mushy.

Another common mistake is overcrowding the skillet while searing the chicken, which leads to steaming rather than browning. Cook the chicken in batches if necessary to ensure it develops a deep, flavorful sear that adds significant character to the final baked dish.

How to tell it’s done

The dish is considered done when the internal temperature of the chicken reaches 165°F (74°C) and the cheese topping is golden-brown and bubbling across the entire surface.

The cream sauce should have reduced significantly, clinging to the pasta rather than sitting as a thin liquid at the bottom of the dish. If the cheese browns too quickly, cover the dish loosely with foil for the final few minutes of baking to ensure the interior reaches the desired temperature.
