How to Make Ultimate Chicken Spaghetti Recipe
Step 1: Prepare Your Oven and Pasta
Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking dish, which will hold all those wonderful layers. Next, cook the spaghetti according to the package instructions until it is perfectly al dente, then drain it well. Having your pasta ready is essential before moving on so that everything comes together in the final bake.
Step 2: Sauté the Vegetables
In a large skillet, melt butter over medium heat and add the diced onion, green bell pepper, and minced garlic. Sauté them until they are soft and fragrant, which should take about 3 to 4 minutes. This step releases their natural sweetness and builds a flavorful foundation for your sauce.
Step 3: Mix in the Creamy Ingredients
To the softened veggies, stir in the cream of chicken soup, cream of mushroom soup, drained Rotel tomatoes, and chicken broth. Mix thoroughly to combine all components into a smooth, creamy mixture. This sauce is what makes the Ultimate Chicken Spaghetti Recipe so irresistibly rich and comforting.
Step 4: Add Spices and Chicken
Sprinkle in the Italian seasoning, paprika, salt, and pepper. Stir well, then reduce the heat to low and fold in your shredded chicken, making sure every tender piece is coated with the luscious sauce. This step infuses the dish with layers of savory flavor.
Step 5: Combine Pasta and Sauce
Now, add the cooked spaghetti directly into the skillet with the sauce, gently tossing everything together until the pasta is evenly covered. This ensures that every bite delivers that perfect balance of creaminess, seasoning, and chicken goodness.
Step 6: Assemble and Bake
Transfer the spaghetti mixture into the prepared baking dish. Evenly sprinkle the shredded cheddar, mozzarella, and grated Parmesan cheeses over the top. Bake uncovered for 25 to 30 minutes, until the cheese is melted, bubbly, and golden. This final step brings all the flavors together with a gorgeously cheesy crust.
Step 7: Rest Before Serving
Allow the dish to rest for about 5 minutes after baking. This helps it set slightly, making it easier to serve and letting the flavors meld even more beautifully. Now you’re ready to dive into the Ultimate Chicken Spaghetti Recipe!
