Ingredients You’ll Need
- 3 cups cooked chicken: Use shredded rotisserie chicken for convenience, or poach chicken breast for a healthier version.
- 1 pound spaghetti: Cook this for one minute less than indicated on the box. It will finish cooking in the oven.
- 1 teaspoon kosher salt: This enhances all the flavors in the dish.
- 3 cups grated cheddar cheese: A good melting cheese adds creaminess; feel free to mix with mozzarella for a different flavor.
- 4 ounces cream cheese: This adds luscious creaminess to the dish.
- 2 (10.5 ounce cans) condensed cream of mushroom soup: This forms the base of your sauce, lending a rich flavor.
- 1 cup chicken broth: Helps to achieve the right consistency in the sauce; low sodium varieties are recommended.
- 1 (10 ounce can) diced tomatoes with green chiles: Brands like Rotel add a nice kick and color; if you prefer a milder taste, use regular diced tomatoes.
- 2 teaspoons onion powder: For that savory depth.
- 2 teaspoons garlic powder: Adds wonderful flavor without the fuss of chopping fresh garlic.
How to Make Chicken Spaghetti That Makes Dinner So Easy
- Preheat the oven: Set your oven to 350 degrees Fahrenheit and spray a 9 by 13 inch casserole dish with cooking spray. This prevents sticking and ensures easy cleanup later.
- Cook the spaghetti: Bring a large pot of water to a rolling boil. Add in your uncooked spaghetti along with the kosher salt. Cook for one minute less than the package instructions indicate—if the box says eight to ten minutes, cook for just seven.
- Mix your ingredients: In the same pot the spaghetti was cooked in, combine two cups of grated cheddar cheese, cream cheese, cream of mushroom soup, chicken broth, diced tomatoes with green chiles, onion powder, and garlic powder. Stir until everything is well blended.
- Combine chicken and spaghetti: Gently fold in the cooked chicken and the drained spaghetti, ensuring everything is coated in the creamy mixture.
- Assemble the casserole: Pour the entire mixture into the prepared casserole dish and spread it out evenly. Top with the remaining one cup of cheddar cheese.
- Bake: Place the casserole in the oven and bake uncovered for 20 to 30 minutes, or until the cheese is melted and bubbling at the edges.
Storing & Reheating
To store Chicken Spaghetti, let it cool completely at room temperature before placing it in an airtight container. It can be kept in the refrigerator for up to 3 days. If you want to freeze it, transfer the cooled casserole to a freezer-safe container, where it can last up to 3 months. To reheat, simply thaw overnight in the refrigerator, then pop it in a preheated oven at 350 degrees Fahrenheit for about 25 minutes, or until it’s heated through. Please note that while reheating can alter the texture slightly, a sprinkle of extra cheese before baking can revitalize its creamy consistency.
Chef’s Helpful Tips
- Avoid overcooking the spaghetti; it will cook further in the oven, so al dente is your best bet.
- If you prefer fresh flavors, consider adding sautéed onions and bell peppers to the mix for added texture and taste.
- To elevate the flavor further, sprinkle a bit of smoked paprika or cayenne pepper into the mixture for a smoky or spicier kick.
- Feel free to swap out the cheese for a blend that matches your preferences; pepper jack or gouda can add unique twists.
- If you have leftovers, save some extra cheese for a second bake to bring back that fresh-from-the-oven taste.
As you embark on your journey to create Chicken Spaghetti that makes dinner so easy, remember the joy that comes from cooking. This dish thrives on creativity, so don’t hesitate to make it your own.
