Step‑by‑Step Instructions for Easy Chicken Spaghetti Recipe

Step 1: Preheat the Oven and Prepare the Dish
Begin by preheating your oven to 350°F (175°C). While it’s heating, lightly grease a 9×13 baking dish with cooking spray or butter to prevent sticking. This will create a perfect home for your creamy Southern chicken spaghetti casserole, keeping it from browning unevenly.

Step 2: Cook the Spaghetti
In a large pot, bring salted water to a boil, then add 12 ounces of spaghetti. Cook according to package directions but reduce the time by two minutes for al dente pasta. Once cooked, drain the spaghetti but do not rinse it; this helps the sauce cling better to the noodles.

Step 3: Sauté the Vegetables
In a skillet, heat 1 tablespoon of butter and 1 tablespoon of olive oil over medium heat. Add 1 finely diced onion and 1 diced bell pepper, sautéing for about 4-5 minutes until they become tender. Stir in 3 minced garlic cloves along with 1 teaspoon of Italian seasoning, cooking for an additional minute until fragrant.

Step 4: Create the Sauce
Lower the heat and stir in a 10.5-ounce can of cream of chicken soup, a 10-ounce can of diced tomatoes with green chiles, ½ cup of chicken broth, ½ cup of sour cream, and 4 ounces of softened cream cheese. Mix everything together until it’s smooth and creamy, creating a luxurious base for your chicken spaghetti.

Step 5: Combine Chicken and Pasta
Gently fold in 3 cups of cooked chicken and half of the 2 cups of shredded cheddar cheese into the sauce. Once well combined, add the drained spaghetti to the mixture and carefully stir until every strand is coated with that rich, creamy sauce.

Step 6: Transfer to Baking Dish
Pour the entire mixture into your pre-prepared 9×13 baking dish, spreading it out evenly. Make sure the pasta and chicken are well-distributed so that each bite is perfectly flavorful. Sprinkle the remaining cheddar cheese over the top to create a deliciously cheesy crust when baked.

Step 7: Bake the Casserole
Place the baking dish in the preheated oven and bake uncovered for 25-30 minutes. Look for the casserole to be bubbly with a golden-brown top. This visual cue indicates that it’s ready to come out, delivering that irresistible cheesy goodness.

Step 8: Let it Rest Before Serving
Once removed from the oven, allow the casserole to rest for about 10-15 minutes. This resting time lets the flavors meld together beautifully. Optionally, garnish with 2 tablespoons of chopped fresh parsley for a pop of color and fresh flavor before serving your comforting easy chicken spaghetti recipe.

Expert Tips for Easy Chicken Spaghetti Recipe

Cook it al dente: Always under-cook the spaghetti by two minutes to keep it pleasantly chewy after baking.
Layer the flavors: Reserve some cheddar cheese for the top to create a crispy, cheesy layer that contrasts beautifully with the creamy filling.
Mix it right: Gently fold the chicken into the creamy mixture to keep it tender and juicy throughout the baking process.
Mingle overnight: For extra flavor, let your casserole sit in the fridge overnight before baking; the flavors develop and only get better!
Customize seasoning: Taste your sauce prior to assembly. It’s crucial to adjust the salt and pepper according to your preference for the best chicken spaghetti experience.

Storage Tips for Easy Chicken Spaghetti

Fridge: Store leftover easy chicken spaghetti in an airtight container for up to 3-4 days. This keeps the casserole fresh and ready to enjoy.

Freezer: For longer storage, freeze the casserole once it has cooled completely. Use a freezer-safe container and it will keep well for up to 3 months.

Reheating: To reheat, thaw overnight in the fridge, and then bake at 350°F (175°C) for around 25-30 minutes, until heated through and bubbly.

Serving Tips: If desired, add a splash of chicken broth before reheating to restore some creaminess to your easy chicken spaghetti.

Make Ahead Options

These easy chicken spaghetti casserole is perfect for meal prep enthusiasts! You can prepare the entire mixture up to 24 hours in advance. Simply follow all the instructions until Step 5, then cover and refrigerate the unbaked casserole. To maintain its quality and flavor, keep it tightly covered to prevent drying out. When you’re ready to bake, preheat your oven and let it sit at room temperature for about 30 minutes before popping it in. Bake according to Step 7 (25-30 minutes) until it’s bubbly and golden brown. Enjoy a delicious, comforting meal with minimal effort on busy weeknights!
