Before you start

Before beginning, ensure that your chicken is pre-cooked and shredded, and your bacon is cooked until crispy and crumbled. Preheat your oven to 375°F (190°C) so it is ready for the baking dish.

Gather all your ingredients and measuring tools on the counter to streamline the assembly process. Boiling the water for the pasta should be the very first step, as the pasta will be the foundation of the entire dish. Having everything prepped makes the process smooth and efficient.

Ingredients at a glance (7)
  • 1 lb penne pasta
  • 2 cups cooked chicken breast, shredded
  • 6 slices bacon, cooked and crumbled
  • 1 cup ranch dressing
  • 1/2 cup heavy cream
  • 2 cups mozzarella cheese, shredded
  • 1 cup cheddar cheese, shredded

Instructions

Boiling the pasta

  1. Prepare the pasta
    Bring a large pot of salted water to a boil. Add the penne pasta and cook according to the package instructions until al dente. Drain the pasta using a colander and set aside.
    Look for The pasta should be firm to the bite.
    Tip Do not overcook the pasta as it will continue cooking in the oven.

The pasta should be cooked until it is al dente, meaning it should have a slight chew when bitten. Drain it thoroughly to prevent excess water from diluting the rich ranch sauce, which would otherwise lead to a runny consistency that prevents the casserole from setting properly in the final stage.

Mixing the base

  1. Mix the ingredients
    In a large mixing bowl, combine the cooked penne, shredded chicken breast, half of the bacon bits, ranch dressing, and heavy cream. Stir until the pasta is evenly coated in the creamy mixture.
    Look for The sauce should evenly coat every piece of pasta.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Gently fold the chicken to keep the pieces intact.

The sauce should be thick and creamy, coating the pasta and chicken evenly without pooling at the bottom of the bowl. If the mixture seems too thick, incorporate a small amount of heavy cream.

Ensure that the ingredients are thoroughly combined so that every bite contains a balanced ratio of chicken, bacon, and sauce.

Baking the dish

  1. Bake the casserole
    Preheat the oven to 375°F (190°C). Transfer the pasta mixture into a 9x13 inch baking dish. Top with the remaining bacon, mozzarella, and cheddar cheese. Bake for 20 minutes or until the cheese is bubbly and golden brown. Let rest for 5 minutes before serving.
    Look for The cheese should be melted, bubbly, and slightly browned on the edges.
    Tip Use a broiler for the last minute if you prefer an extra golden crust.

The casserole is ready when the surface is bubbling and the cheese has developed a golden, toasted appearance. The edges should show signs of the sauce thickening and caramelizing slightly. Let the dish rest for five minutes to allow the sauce to thicken slightly, resulting in a cohesive, scoopable texture.

Common mistakes

A common mistake is overcooking the pasta before it hits the oven; ensure you stop the boiling process when the pasta is just al dente, as it will continue to absorb moisture and soften during the baking phase.

Another error is using too little sauce; if the pasta looks dry, add a splash more heavy cream before putting it into the oven to ensure it remains creamy and delicious throughout the final cooking stage.

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. Since the chicken and bacon are already cooked, the goal is to heat the entire mixture through and achieve the desired texture on the cheese.

The internal temperature of the chicken should reach at least 165°F (74°C) to ensure safety. Always allow the dish to rest for five minutes after removing it from the oven to let the sauce set slightly before serving.
