This recipe prevents soggy pasta, dry chicken, and lack of flavor by cooking pasta al dente, keeping chicken moist, and using the same skillet.

Ingredient Notes

  • Chicken breasts: You’ll need these to provide a nice base for the bake. If you’re in a pinch, thighs or ground chicken work just fine!
  • Spaghetti: Uncooked spaghetti is key here; it absorbs flavors as it bakes. Just remember to cook it al dente so it doesn’t turn mushy later!
  • Salted butter: This adds richness and a lovely creaminess to the dish. Make sure it’s at room temperature for easier blending into your sauce.
  • Heavy cream: This ingredient gives the sauce its rich and luscious texture. If you want a lighter option, you can swap in half-and-half.
  • Diced tomatoes with green chiles: This brings in a nice kick! If you’re not into the heat, plain diced tomatoes would also work beautifully.

Recipe Tips

  • If pasta becomes too soft, cook spaghetti until al dente, about 2 minutes less than package instructions.
  • When chicken is cooked, make sure it reaches a golden brown for juicy, flavorful results.
  • For a creamy sauce consistency, add a splash of chicken broth if it gets too thick while baking.
  • If there’s a raw taste from the flour, remember to cook it for 2-3 minutes before adding liquids.
  • When creating the sauce, use the same skillet to keep all the wonderful flavors from the chicken.

Serving Suggestions

  1. Serve chicken spaghetti with crusty garlic bread and a fresh side salad for a hearty meal. A sprinkle of parsley adds a touch of green to the dish.
  2. This chicken spaghetti also works well in casseroles or as a filling for stuffed peppers. Consider using it in baked dishes or layered in a lasagna-style recipe.
  3. Top with a homemade marinara or a creamy alfredo sauce for an extra kick. A dash of crushed red pepper flakes can add warmth if desired.

Storage Guidelines

  • To keep your chicken spaghetti fresh, follow these storage tips:
  • Refrigeration: Store leftovers in an airtight container in the fridge for up to 4 days, maintaining temperature and freshness.
  • Freezing: Wrap in plastic wrap or aluminum foil, then place in a freezer bag. Freeze for up to 2 months. Thaw in the fridge.
  • Reheating: Reheat chicken spaghetti in the microwave or oven until heated through, ensuring proper temperature before serving.

Recipe Variations

  • You can use boneless, skinless chicken thighs instead of chicken breasts for a juicier option.
  • Add 1 teaspoon garlic powder or 1 tablespoon fresh minced garlic for a punch of flavor.
  • Either substitute ground chicken for a different texture, or replace the spaghetti with a gluten-free pasta.
  • If you double the recipe, you’ll need 4 chicken breasts and 16 oz of spaghetti for a larger serving size.

Course: Main Course
Cuisine: American

Equipment

  • Large deep skillet
  • Large pot
  • Colander
  • 9×13 casserole dish

Ingredients

  • 2 pieces chicken breasts boneless, skinless, (about 1.5 lb total)
  • 1 Tbsp olive oil
  • ½ Tbsp salt for the pasta water
  • 8 oz spaghetti uncooked
  • ¼ cup salted butter
  • 1 piece onion diced
  • 2 pieces garlic cloves minced
  • ¼ cup all-purpose flour
  • 2 cups chicken broth
  • ½ tsp salt
  • ¼ tsp black pepper
  • ½ tsp Italian seasoning
  • 1 cup heavy cream
  • 1 10oz can diced tomatoes with green chiles drained, (Rotel)
  • 1 cup cheddar cheese shredded, (divided)
  • 1 cup mozzarella cheese shredded, (divided)

Instructions

  • Start by heating olive oil in a skillet over medium heat until shimmering. Add the chicken breasts and cook until they are golden and no longer pink in the middle. Be careful not to overcook; dry chicken is a common mistake.
  • While the chicken is cooking, boil water in a separate pot and season it with salt. Toss in the uncooked spaghetti, cooking it just until al dente. This will keep your pasta from becoming mushy during baking.
  • Once the chicken is done, set it aside and add diced onions to the skillet. Sauté until they are softened and translucent. Add minced garlic and let it become aromatic.
  • Sprinkle flour over the sautéed onion mixture. Stir for 2-3 minutes until it is lightly golden to eliminate any raw flour taste.
  • Gradually pour in the chicken broth and heavy cream, stirring continuously until the mixture is smooth and slightly thickened.
  • Mix in salt, black pepper, Italian seasoning, and the diced tomatoes. Taste and adjust seasonings as desired.
  • Add the cooked spaghetti to the skillet and stir until every noodle is coated with the creamy sauce.
  • Transfer half of the pasta mixture to a baking dish and sprinkle half of both cheese types on top.
  • Spread the rest of the spaghetti mixture over the first layer and top with the remaining cheddar and mozzarella.
  • Slip the baking dish into a preheated oven and bake until the top is golden and the cheese is bubbling.

Notes

Storage Tips: Store leftovers in an airtight container in the fridge for up to 3-4 days.
Expert Tips: Cook spaghetti until al dente to avoid mushiness when baking. Use the same skillet for the sauce to retain flavor from cooking the chicken. Stir in a splash of chicken broth if the sauce becomes too thick while baking.
Reheating Instructions: Reheat in the oven at 350 degrees F for about 20 minutes or until heated through.
Serving Suggestions: Serve with crusty garlic bread or a fresh side salad. Add a sprinkle of parsley for color.
Recipe Variations: Add sliced mushrooms for an earthy flavor or mix in some spinach for added nutrition.
Ingredient Notes: When selecting chicken, look for fresh boneless and skinless breasts or thighs. For a budget-friendly option, ground chicken can also be used.
