Creamy Chicken Spaghetti Bake with Bacon and Cheddar Tips, FAQ & printable recipe

Tips for success

For an extra kick of flavor, add a pinch of red pepper flakes into the creamy sauce before mixing. This subtle heat balances the richness of the alfredo sauce and pairs wonderfully with the smoky bacon.

You can also add some freshly chopped parsley or chives after baking for a pop of color and a fresh, herbaceous finish.

If the top of the dish browns too quickly, tent the baking dish loosely with aluminum foil for the first 15 minutes of baking. This allows the center to heat through properly without burning the cheese. Remove the foil for the final 10 minutes to allow the cheese to melt fully and develop a beautiful golden color.

Variations

• Spicy Cajun Chicken Bake: Add a tablespoon of Cajun seasoning to the sauce and include sautéed bell peppers and onions in the mixture. This adds a bold, spicy kick that complements the creamy alfredo base perfectly.
• Spinach and Mushroom Version: Stir in two cups of fresh baby spinach and a cup of sautéed mushrooms into the pasta. The spinach wilts into the sauce, adding earthiness and color to the dish.

Storage and make-ahead

Fridge

Keep in an airtight container for up to 3 days.

Freezer

Freeze in a freezer-safe container for up to 2 months.

Reheat

Reheat in the oven at 350°F until warmed through, or microwave individual portions until hot.

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Ensure the dish has cooled completely at room temperature for no more than 2 hours before transferring it to the fridge. Using a shallow container will help the pasta cool faster and maintain better quality when stored.

You can assemble the bake ahead of time, but wait to add the bacon bits until just before baking to keep them crispy.

Cover the assembled dish tightly with plastic wrap and refrigerate for up to 24 hours. When ready to eat, remove the plastic wrap and bake as directed, adding a few extra minutes to the total cook time.

Serving ideas

This creamy chicken spaghetti bake is a substantial meal on its own. Serve it with a crisp green salad tossed in a light vinaigrette to provide a refreshing contrast to the richness of the pasta.

A side of roasted vegetables, such as broccoli or asparagus, also makes for a balanced and colorful addition to the plate.

For a complete dinner, consider serving a loaf of warm, crusty garlic bread on the side. This is perfect for soaking up any extra creamy sauce left on the plate.

If serving for a larger group, you can easily double the recipe and use two baking dishes, adjusting the cooking time as necessary for the increased volume.

Creamy Chicken Spaghetti Bake with Bacon and Cheddar

Prep 15 minCook 30 minRest 5 minTotal 50 minServes 6

Ingredients

• 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

1. 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.
2. 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.
3. 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.
