Step by Step Instructions

Step 1: Start by boiling 12 ounces of uncooked penne pasta according to the package directions. If you prefer your pasta to be slightly firmer, cook it for a minute or two less than the recommended time. Drain the pasta and set it aside.

Step 2: In a large bowl, combine 3 cups of shredded cooked chicken breast, half of the 8 slices of crispy bacon (4 slices), 3 cups of Alfredo sauce, 1 packet of ranch seasoning, 1 cup of shredded mozzarella cheese, and ¼ cup of shredded parmesan cheese. Season with salt and pepper to taste.

Step 3: Add the cooked penne pasta to the mixture and stir everything together until the pasta is evenly coated with the creamy filling. Ensure that all the ingredients are well combined.

Step 4: Transfer the pasta and filling mixture into a prepared 9 x 13-inch baking dish. Spread it out evenly, and top with the remaining chopped bacon, mozzarella cheese, and parmesan cheese. Bake in the preheated oven at 375°F (190°C) for 15-20 minutes, or until the cheese is melted and bubbly with a golden brown top.
Expert Tips
- Undercook the pasta: To ensure the pasta doesn’t get too soft during baking, cook it for a minute or two less than the package directions.
- Crispy bacon: Make sure the bacon is nice and crispy before adding it to the mixture for the best texture.
- Add extra cheese: If you love cheese, feel free to add more mozzarella and parmesan for an extra cheesy finish.

Instructions
- Cook the pasta: Preheat the oven to 375°F (190°C). Cook the penne pasta according to the package directions, slightly undercooking it for a firmer texture. Drain the pasta and set it aside.
- Prepare the filling: In a large bowl, combine the shredded chicken, chopped crispy bacon, Alfredo sauce, ranch seasoning, half of the shredded mozzarella cheese, and half of the shredded parmesan cheese. Season with salt and ground black pepper to taste.
- Mix pasta and filling: Add the cooked penne pasta to the bowl with the filling. Stir everything together until the pasta is fully coated with the creamy mixture.

Notes
- For a spicier version, add red pepper flakes to the Alfredo sauce or sprinkle some over the top before baking.
- You can substitute the penne pasta for another shape like ziti or rigatoni.
- To make the casserole ahead, prepare it up to step 4, cover, and refrigerate. Bake when ready, adding a few extra minutes to the cooking time if it’s chilled.
- For the best results, use freshly shredded mozzarella and parmesan instead of pre-shredded cheese. Fresh cheese melts better, creating a smoother, creamier texture in your casserole.
