Step‑by‑Step Instructions for Cheesy Chicken Spaghetti Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step ensures that your Cheesy Chicken Spaghetti Casserole cooks evenly and achieves that perfect bubbly, golden crust. While the oven warms up, gather your ingredients, so everything is ready to combine seamlessly.

Step 2: Cook the Spaghetti
Break the spaghetti into thirds, then bring a large pot of salted water to a boil. Add the spaghetti and cook for 6-7 minutes, just until al dente, as it will continue cooking in the oven. Drain the pasta and set it aside, allowing it to cool slightly while you prepare the other ingredients.

Step 3: Combine Ingredients
In a large mixing bowl, combine the cooked spaghetti with shredded chicken, cream of mushroom soup, cream of chicken soup, diced pimentos, and chopped bell peppers. Stir in minced onion, minced garlic, chicken broth, and a pinch of cayenne pepper. Mix until everything is well coated, creating a creamy base for your casserole.

Step 4: Prepare the Casserole Dish
Spray a 9×13-inch casserole dish with cooking spray to prevent sticking. Spoon the chicken and spaghetti mixture into the dish, spreading it evenly. Make sure every bite will be filled with that marvelous cheesy flavor, and don’t forget to reserve half a cup of grated cheddar cheese for the top.

Step 5: Add the Cheese Topping
Sprinkle the reserved cheddar cheese generously over the top of the chicken spaghetti mixture. This layer will melt beautifully and create a gooey finish that is simply irresistible. Ensure the cheese covers as much of the casserole as possible for that attractive, bubbly look once baked.

Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake for 30 minutes. Keep an eye on it during the last few minutes; the cheese should be melted and bubbly, and the edges should start to turn a light golden brown, indicating it’s ready to come out and be served.

Step 7: Cool and Serve
Once the casserole is done baking, carefully remove it from the oven and let it sit for about 5 minutes before serving. This cooling time allows the flavors to meld together and makes it easier to serve. Gather your loved ones and enjoy this comforting Chicken Spaghetti Casserole!

Storage Tips for Chicken Spaghetti Casserole

Fridge: Store the casserole in an airtight container for up to 3 days to keep the flavors fresh and delicious.

Keeping the components separate until just before baking helps maintain the casserole’s texture and ensures it’s just as delicious as when freshly made!

Chicken Spaghetti Casserole Recipe FAQs

How do I choose ripe bell peppers for this casserole?
Absolutely! Look for bell peppers that are firm and free of blemishes or dark spots. A shiny, smooth skin indicates freshness, while vibrant colors mean they’re packed with flavor. Whether you choose green, orange, or red, just make sure they feel heavy for their size, indicating they’re juicy and fresh.

What’s the best way to store leftovers of my Chicken Spaghetti Casserole?
Very! After your meal, let the casserole cool completely before transferring it to an airtight container. It can be stored in the fridge for up to 3 days. If you want to keep it longer, wrap it tightly in plastic wrap and then cover it with foil before freezing. This way, it will stay tasty for up to 4 months!

Can I freeze Chicken Spaghetti Casserole? How?
Of course! To freeze your casserole, let it cool down completely after baking. Once cooled, wrap it tightly in plastic wrap, followed by a layer of aluminum foil to prevent freezer burn. Label the package with the date and it will keep well for up to 4 months. When you’re ready to enjoy it again, thaw it overnight in the fridge and reheat in the oven at 350°F for about 20-25 minutes or until heated through.

What if my casserole is too dry after baking?
No worries! If you find that your casserole is a bit dry after baking, it may be a sign that the pasta was too cooked or the sauce didn’t have enough moisture. You can remedy this by adding a splash of chicken broth or milk when mixing the ingredients next time, ensuring you have a creamy base. Adding an additional layer of cheese on top can also keep it rich and moist while it bakes!

Are there any dietary considerations to keep in mind with this dish?
Definitely! This Chicken Spaghetti Casserole is easily adaptable to accommodate various dietary needs. For a vegetarian option, swap out the chicken with your favorite veggies or beans.
