Ultra-Creamy Chicken Spaghetti Bake with Crispy Bacon Tips, FAQ & printable recipe

Tips for success

To enhance the depth of flavor in your cream sauce, try adding a splash of dry white wine to the skillet right after searing the chicken.

This helps deglaze the pan, scraping up all the delicious browned bits of chicken stuck to the bottom while adding a bright acidity that cuts through the rich cream and cheese before you add the pasta.

If you prefer an extra kick of flavor, you can stir in a small can of drained diced green chiles or a handful of chopped pickled jalapeños into the pasta mixture before baking. This adds a subtle, smoky heat that pairs wonderfully with the cheddar and bacon without overpowering the creamy texture of the dish.

Variations

• Spicy Cheddar: Swap the regular cheddar for pepper jack cheese and add a pinch of cayenne pepper to the cream sauce for a spicy kick.
• Broccoli and Chicken: Stir in two cups of small broccoli florets along with the pasta to add some color and texture to the creamy bake.
• Garlic Herb Crust: Mix a half cup of panko breadcrumbs with melted butter and dried parsley, then sprinkle it over the cheese before baking.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days, cooling it for no more than 2 hours first.

Freezer

Freeze the assembled, unbaked casserole wrapped tightly in foil for up to 2 months. Thaw in the fridge overnight before baking.

Reheat

Reheat individual portions in the microwave, or cover the baking dish with foil and bake at 350°F (175°C) until hot and bubbling.

Store any leftover chicken spaghetti bake in an airtight container in the refrigerator for up to three to four days. To prevent the pasta from drying out, ensure the container is tightly sealed.

When storing, allow the casserole to cool down to room temperature for no more than two hours before placing it in the fridge to maintain food safety standards.

This dish is highly suitable for making ahead of time. Assemble the entire casserole in the baking dish, cover it tightly with plastic wrap or aluminum foil, and store it in the refrigerator for up to twenty-four hours before baking.

When ready to serve, remove the cover and bake as directed, adding about five to ten minutes to the baking time to account for the cold dish.

Serving ideas

Serve this rich and creamy bake alongside a light, crisp green salad tossed with a simple vinaigrette to balance out the hearty flavors of the cheese and pasta.

Steamed broccoli, roasted asparagus, or green beans also make excellent side dishes, adding a vibrant color and a fresh, crunchy element to the plate that complements the velvety texture of the casserole.

For an extra touch of indulgence, serve this dish with warm garlic bread or crusty artisan bread. The bread is perfect for wiping up any extra creamy sauce left on the plate. Garnish the top of the bake with a sprinkle of freshly chopped Italian parsley or sliced green onions right before serving to add a pop of color and freshness.

Ultra-Creamy Chicken Spaghetti Bake with Crispy Bacon

Prep 15 minCook 30 minRest 5 minTotal 50 minServes 6

Ingredients

• 12 oz spaghetti
• 1 1/2 lb boneless skinless chicken breasts, cut into chunks
• 1 1/2 cups heavy cream
• 2 cups shredded cheddar cheese, divided
• 1/2 cup bacon bits

Instructions

1. Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente, about 8 to 10 minutes. Drain the pasta thoroughly and set it aside.
2. Heat a large skillet over medium-high heat. Add the chicken chunks and cook, stirring occasionally, until golden brown and cooked through to a safe internal temperature of 165°F (74°C), about 6 to 8 minutes.
3. In the same skillet over medium heat, pour in the heavy cream. Bring to a gentle simmer and let it reduce slightly for 2 to 3 minutes, stirring occasionally to scrape up any browned bits from the chicken.
4. Stir half of the shredded cheddar cheese into the warm heavy cream until completely melted and smooth. Add the cooked spaghetti and chicken chunks to the skillet, tossing gently until everything is coated in the creamy sauce.
5. Transfer the creamy pasta mixture into a 9x13-inch baking dish, spreading it into an even layer. Sprinkle the remaining shredded cheddar cheese and the bacon bits evenly over the top.
6. Bake in the preheated oven at 375°F (190°C) for 15 to 20 minutes. The cheese on top should be melted, bubbling, and lightly golden brown. Remove from the oven and let rest for 5 minutes before serving.
