How to Make thern Cheesy Chicken Spaghetti Casserole
Step 1: Prep Your Oven and Dish
Start by preheating your oven to 350°F (175°C), then grease a large casserole dish so nothing sticks. This little step ensures you’ll get each delicious, golden-brown bite out of the pan in perfect form.
Step 2: Cook the Chicken
Add your chicken breasts to a large pot over medium heat. Give them about 6–7 minutes per side until they’re golden and cooked all the way through. Once finished, shred the chicken using two forks (or your hands if you’re feeling adventurous). This keeps the savory protein tender and ready to soak up the creamy sauce.
Step 3: Boil the Spaghetti
In a separate pot, bring salted water to a boil. Drop in the spaghetti and cook until it just hits al dente—usually 8–10 minutes should do the trick. Drain your noodles but don’t rinse! You want the starch to help everything bind together later.
Step 4: Mix It All Up
Grab a big mixing bowl and toss in the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne, garlic powder, and half of your shredded cheddar cheese. Stir well until everything’s mingling together happily—this is where the flavors really come alive!
Step 5: Assemble and Bake
Scoop the mixture into your prepared casserole dish and spread it evenly. Sprinkle the rest of the cheddar cheese generously on top. Pop it in the oven and bake for 25–30 minutes, until the cheese bubbles and turns a mouthwatering golden brown.
Step 6: Garnish and Serve
Once out of the oven, let the casserole rest for about 5 minutes (it’s hard, we know). Scatter green onions over the top—they add freshness and make everything look extra special. Now, it’s ready to enjoy!

Garnishes
To take your thern Cheesy Chicken Spaghetti Casserole from “yum” to “wow,” don’t skip the green onions—they bring a burst of color and a fresh finish. For even more Southern flair, you could add a dusting of extra paprika or a sprinkle of chopped fresh parsley.
Side Dishes
This casserole loves good company! Pair it with a crisp green salad, classic cornbread, or lightly steamed green beans to balance the richness. A cold glass of sweet tea on the side never hurt either.
Creative Ways to Present
Try scooping individual servings into wide, shallow bowls for a cozy presentation, or serve from the casserole dish right at the table for a homey, family-style feel. You can even bake it in individual ramekins for fun, single-serve portions—perfect for entertaining!
Make Ahead and Storage
Storing Leftovers
Leftover thern Cheesy Chicken Spaghetti Casserole keeps beautifully in the fridge for up to 4 days. Just cover the dish with foil or transfer portions into airtight containers to lock in that cheesy freshness.
Freezing
This casserole is a meal-prep dream! Assemble it (but hold the final bake), wrap tightly, and pop it in the freezer for up to two months. When you’re ready, thaw overnight in the refrigerator, then bake as usual for that just-made magic.
Reheating
To bring leftovers back to life, reheat covered in a 350°F (175°C) oven for 20–25 minutes or until hot and bubbly. For individual portions, the microwave works in a pinch—just add a splash of milk or cream before reheating to keep everything creamy and delicious.
FAQs
Can I use rotisserie chicken instead of cooking chicken breasts?
Absolutely! Rotisserie chicken saves time and adds an extra layer of flavor to your thern Cheesy Chicken Spaghetti Casserole. Just shred the cooked chicken and mix it in as directed.

Is there a way to make it less spicy?
Yes, you can easily dial back the cayenne or skip it altogether if serving younger eaters or those who prefer a milder casserole. It’ll still have loads of Southern flavor from the other spices!
Can I add more vegetables to this casserole?
Definitely—feel free to toss in mushrooms, peas, or spinach for even more color and nutrition. Just be sure to sauté any extra veggies first so they’re tender before mixing in.
