Step‑by‑Step Instructions for Spaghetti Chicken Casserole
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). While it warms up, grab a 9×13-inch baking dish and grease it lightly to prevent sticking. This will ensure your Spaghetti Chicken Casserole comes out easily and beautifully, ready for that perfect golden finish.
Step 2: Mix the Sauces
In a large mixing bowl, combine the cream of mushroom soup, cream of chicken soup, and sour cream. Add garlic powder, salt, black pepper, and paprika for extra flavor. Whisk everything together until the mixture is smooth and well-blended, creating that rich base to envelop your casserole.
Step 3: Add Chicken and Vegetables
Once your sauce is smooth, it’s time to add the shredded chicken, diced tomatoes, and the chopped bell peppers and onion. Stir gently but thoroughly to ensure each ingredient is coated in the creamy sauce. This will bring out the wonderful flavors in the Spaghetti Chicken Casserole as it bakes.
Step 4: Incorporate the Cheese
Fold in 1 cup of the shredded cheddar cheese into your chicken and vegetable mixture. This cheese adds a lovely cheesiness that will meld beautifully during baking. Make sure to mix until it’s evenly distributed, bringing a delicious creaminess to your casserole.
Step 5: Combine with Spaghetti
Gently fold in the cooked spaghetti, making sure every strand is coated with that luscious sauce. Use tongs to carefully mix to prevent breaking the spaghetti. You want each piece of pasta to absorb the flavors that make the Spaghetti Chicken Casserole so comforting and inviting.
Step 6: Transfer to Baking Dish
Carefully transfer the entire mixture into your prepared baking dish, spreading it out evenly with a spatula. This helps ensure that your casserole bakes uniformly, allowing the flavors to meld beautifully together while it cooks in the oven.
Step 7: Add Cheese Topping
Sprinkle the remaining cup of shredded cheddar cheese over the top of the casserole. This will create a delightful, melted cheese crust that adds both flavor and texture to your Spaghetti Chicken Casserole, making it even more appetizing when it comes out of the oven.
Step 8: Bake Until Golden
Place the casserole in the preheated oven and bake it uncovered for 30–35 minutes. Keep an eye on it; you’ll know it’s ready when the cheese is golden and bubbling and the edges start to lightly brown. This ensures that your dish is both hot and flavorful.
Step 9: Optional Broil for Crispy Topping
For an extra crispy cheese topping, switch your oven to broil for 2–3 minutes after baking. Be vigilant during this step to prevent burning—just until the cheese turns a lovely golden brown. This final touch adds a delightful crunch to your Spaghetti Chicken Casserole.
Expert Tips for Spaghetti Chicken Casserole
Use Rotisserie Chicken: Opting for pre-cooked rotisserie chicken can save time and amplify flavor, making your Spaghetti Chicken Casserole even more delicious.
Blend Well: Ensure that the cream soups and sour cream are mixed thoroughly before adding any other ingredients. This step avoids clumps and guarantees a creamy consistency throughout.
Don’t Overcook: Be cautious when broiling; it only takes a minute or two to transform perfect cheese into burnt bits. Stay close and watch for that golden color.
Tongs for Mixing: Use tongs to stir your spaghetti gently. This method helps keep the strands intact and ensures every bite is evenly coated with the sumptuous sauce.
Customize Your Veggies: Feel free to add or swap vegetables according to your preference or seasonality. More veggies can add nutrition and variety to your Spaghetti Chicken Casserole.
How to Store and Freeze Spaghetti Chicken Casserole
Fridge: Store the casserole in an airtight container for up to 4 days. Make sure it’s fully cooled before sealing to maintain freshness.
Freezer: Freeze the assembled casserole before baking. Wrap tightly in plastic wrap and aluminum foil. It can last up to 3 months, allowing for easy meals later!
Reheating: Thaw overnight in the fridge before reheating. Heat in a 350°F (175°C) oven for about 25–30 minutes until warm, or microwave individual portions until heated through.
Make-Ahead Magic: This Spaghetti Chicken Casserole can be prepped in advance, making it perfect for busy nights or family gatherings—just prepare, store, and bake!
Make Ahead Options
These Spaghetti Chicken Casserole is perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the entire casserole up to 24 hours in advance by assembling it in your baking dish, then covering it tightly with plastic wrap and refrigerating.

Spaghetti Chicken Casserole Recipe FAQs
How do I select the right chicken for this casserole?
Absolutely! For the best flavor and convenience, I recommend using shredded rotisserie chicken. It’s already cooked and adds a depth of flavor that truly elevates the dish. If you’re using raw chicken, ensure it’s cooked thoroughly before shredding to incorporate into the casserole.
What is the best way to store leftovers?
Very simple! Store your Spaghetti Chicken Casserole in an airtight container in the refrigerator for up to 3 to 4 days. If you let it cool completely before sealing, it helps maintain moisture and freshness, so each reheated slice tastes just as delightful.
Can I freeze Spaghetti Chicken Casserole?
Yes, you can! To freeze, assemble the casserole but don’t bake it yet. Wrap the dish tightly with plastic wrap and then cover it with aluminum foil to prevent freezer burn. It can be frozen for up to 3 months. Just remember to thaw it in the fridge overnight before baking.
What should I do if my casserole is too dry?
If your casserole turns out dry, don’t worry! For future preparations, make sure to blend the creamy components (soups and sour cream) thoroughly before adding the pasta; this ensures even distribution of moisture. In case of a dry casserole, you can drizzle a little chicken broth or water over it before reheating.
Is this recipe suitable for gluten-free diets?
Very much so! Simply swap regular spaghetti with gluten-free pasta to make a delicious version for those with gluten sensitivities. Ensure that the cream soups are gluten-free as well, and you’re all set for a comforting meal that everyone can enjoy.
Are there any allergy concerns with the ingredients?
Absolutely! This Spaghetti Chicken Casserole includes common allergens like dairy and gluten (unless alternatives are used). For those with dairy allergies, you can use lactose-free versions of cheese and sour cream. If you’re accommodating different dietary needs, feel free to adjust the ingredients accordingly for everyone at the table!
