Step‑by‑Step Instructions for Creamy Chicken Spaghetti Bake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C) to ensure it’s hot and ready for your creamy chicken spaghetti bake. While the oven heats, grease a 9×13-inch baking dish with cooking spray or a light coating of butter to prevent sticking. This will help achieve a beautifully golden crust on your casserole.
Step 2: Cook the Spaghetti
In a large pot, cook the spaghetti according to package instructions until al dente, usually about 8-10 minutes. Drain the pasta and set it aside, allowing it to cool slightly. This step is crucial, as overcooked spaghetti may turn mushy when combined with the creamy mixture.
Step 3: Sauté the Vegetables
Grab a large skillet and melt 1 tablespoon of butter over medium heat. Add in ½ cup of chopped onion, ½ cup of chopped green bell pepper, and 2 minced garlic cloves. Sauté these vegetables for about 5 minutes until they become tender and fragrant, stirring occasionally to avoid burning. This aromatic blend forms the flavor base for your chicken spaghetti bake.
Step 4: Mix the Creamy Filling
In a large mixing bowl, combine one can each of cream of mushroom soup and cream of chicken soup, along with 1 cup of chicken broth and 1 cup of sour cream. Stir until the mixture is smooth and creamy, ensuring everything is well incorporated. This rich filling is the essence of your creamy chicken spaghetti bake, bringing together all the delicious flavors.
Step 5: Combine Ingredients
Once the creamy mixture is ready, gently stir in 2 cups of shredded cooked chicken, the sautéed vegetables, and seasonings like salt, black pepper, and paprika to taste. Mix everything until well combined, allowing the flavors to meld beautifully, which will enhance the overall taste of your chicken spaghetti bake.
Step 6: Toss in the Spaghetti
Now add the cooked spaghetti to your creamy chicken mixture. Using tongs or a large spoon, carefully toss the spaghetti with the filling until every strand is evenly coated. This step ensures that the flavors are distributed throughout the dish, creating that irresistible creamy chicken spaghetti bake you’re looking for.
Step 7: Transfer to Baking Dish
Transfer the loaded mixture into your greased baking dish, spreading it out evenly. Make sure to press down gently to avoid air pockets, which helps the casserole cook uniformly. The even layer will ensure that every bite of your chicken spaghetti bake is deliciously creamy and hearty.
Step 8: Add Cheese Toppings
Sprinkle 1 cup each of shredded cheddar cheese and mozzarella cheese generously over the top of the casserole. This cheesy layer not only adds flavor but also creates a beautiful, gooey crust as it bakes. Ensure even coverage for the best melted texture when it comes out of the oven.
Step 9: Bake the Casserole
Place the baking dish in the preheated oven and bake the creamy chicken spaghetti bake for 25-30 minutes. Keep an eye on it and remove the foil if the top starts to brown too quickly. It’s done when the cheese is bubbly and golden brown, creating a mouth-watering crust that beckons to be served.
Step 10: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 5 minutes. This resting time allows the flavors to settle and makes it easier to cut into portions. Serve this comforting creamy chicken spaghetti bake warm, and watch your family’s faces light up with delight!
