Before you start

Before beginning, ensure the oven is fully preheated to 375°F (190°C) to ensure an even bake. Cook the spaghetti in a large pot of salted water until al dente, drain well, and set aside.

Ensure the chicken is already shredded or chopped into bite-sized pieces and that the alfredo sauce is at room temperature for easier mixing.

Having all ingredients measured and ready to go will make the assembly process efficient and straightforward, allowing the dish to be ready for the oven in just a few minutes.

Ingredients at a glance (5)
  • 1 lb spaghetti, cooked al dente
  • 2 cups cooked chicken, shredded or cubed
  • 2 cups alfredo sauce, store-bought or made ahead
  • 2 cups shredded cheddar cheese
  • 1/2 cup cooked bacon bits

Instructions

Mixing the Pasta Base

  1. Prepare the Base
    Preheat the oven to 375°F (190°C). In a large mixing bowl, combine the cooked spaghetti, shredded chicken, and alfredo sauce. Stir until the pasta is thoroughly coated in the creamy mixture, ensuring the chicken is evenly distributed throughout the dish.
    Look for The pasta should be uniformly coated in the creamy sauce.
    Tip Ensure the pasta is cooked al dente so it holds its texture during the bake.

The pasta, chicken, and alfredo sauce should be thoroughly combined in the mixing bowl. The mixture should appear creamy and uniform, with no dry clumps of pasta. All components should be well-incorporated before transferring the mixture into the baking dish to ensure consistent flavor in every serving.

Assembling and Baking

  1. Assemble and Bake
    Transfer the pasta mixture into a 9x13 inch baking dish and spread it out evenly. Sprinkle the shredded cheddar cheese and cooked bacon bits over the top. Place the dish in the preheated oven and bake until the cheese is melted and bubbling, reaching an internal temperature of 165°F (74°C) for the chicken.
    Look for The cheese should be melted, golden, and bubbling at the edges.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Cover with foil for the first 15 minutes if the cheese browns too quickly.

The pasta mixture should be spread evenly in the baking dish, topped with a generous layer of cheddar and bacon bits. During baking, the dish should smell aromatic, with the scent of melted cheese and savory bacon filling the kitchen. The cheese should be bubbling and golden.

Resting and Serving

  1. Finish and Serve
    Remove the baking dish from the oven and let it rest for 5 minutes before serving. This allows the sauce to settle and makes for a better presentation when scooping. Serve warm directly from the baking dish.
    Look for The sauce should be slightly thickened and the dish should be steaming.
    Tip Use a metal server to get a good portion of the creamy pasta and melted cheese.

After removing the dish from the oven, allow it to rest for at least 5 minutes. The sauce will thicken slightly, making it easier to scoop. When serving, the cheese should pull away from the dish in long, appetizing strands, indicating the perfect melting point and texture.

Common mistakes

Avoid overcooking the pasta before it goes into the oven, as it will continue to soften during the baking process. If the pasta is too soft initially, it may become mushy in the sauce. Additionally, do not overload the dish with too much sauce, as this can lead to a watery consistency.

Ensure the baking dish is the correct size to allow for even heat distribution, and avoid covering the dish for the entire duration of the bake to ensure the cheese develops a nice texture.

How to tell it’s done

The dish is considered done when the cheese on top is fully melted, bubbling, and shows light golden brown spots. The internal temperature of the chicken throughout the dish must reach 165°F (74°C).

The sauce should be hot and slightly thickened, and the edges of the pasta should be firm but tender. Always use a food thermometer to verify the internal temperature of the chicken in the center of the dish to ensure food safety before serving.
