This cheesy, spicy southern chicken and spaghetti bake wraps you up in comfort and always fills the house with heat and happy chatter. Just grab some regular basics from your pantry, toss in plenty of cheese, and you've got that bold, crowd-favorite flavor for any night you're in the mood for something cheesy and spicy.
First time I made it was for a potluck and it vanished instantly — my cousins still call me up asking for the secret at every big get-together. Now it’s my go-to for Sunday feasts, and even the folks who don't love spicy food end up loving it.
Irresistible Ingredients
- Green onions: Snip the green tops for color and a burst of fresh flavor, right before you serve
- Garlic powder: Gives a mellow garlicky hit, just make sure it’s fresh for max flavor
- Cayenne pepper: Kicks up the spicy punch, grab fresh ground for the best zing, and use more or less as you like
- Paprika: A smoky, cozy addition, good ground paprika means bold, warm color and taste
- Cream of chicken soup: Makes everything creamy and ties it all together, pick a low-salt kind if you want
- Fresh bell peppers: Crisp and sweet, grab firm bright-colored peppers for crunch and sweetness
- Shredded sharp cheddar cheese: The melty, tangy heart of the dish, freshly grated for serious gooeyness
- Spaghetti: Holds the sauciness, choose classic or whole wheat to pump up the fiber
- Boneless skinless chicken breasts: Juicy and meaty, pick firm fresh chicken for the best bite — it soaks up the flavor perfectly
Easy-Peasy Steps
- Finish and Serve:
- Let everything cool for five minutes once it’s out. Sprinkle over the green onion and slice into neat squares and serve up. That little pause makes nicer slices and keeps fingers safe from the heat.
- Bake to Perfection:
- Pop your dish in at 350 degrees and leave it about 25 to 30 minutes. Watch for bubbling cheese and golden corners—that’s when it’s ready.
- Assemble and Top:
- Coat your baking dish with butter or oil then scoop in all that cheesy chicken pasta. Gently spread it out and pile on the leftover cheddar to cover everything in gooey goodness.
- Mix the Filling:
- In a big bowl combine your just-cooked chicken, spaghetti, half your cheese, bell peppers, the soup, and all the spices. Mix everything up so each bite gets cheesy and saucy.
- Prepare the Spaghetti:
- Boil water in a big pot with salt, dump in the spaghetti, and cook about 8-10 minutes. Once it’s just done, drain—but don’t rinse. That little bit of starch helps it all cling together.
- Cook the Chicken:
- Start by cooking chicken breasts in a roomy pot, flipping after about 6-7 minutes until golden and done through. Rest them so they’re juicy, then shred with forks.

The zippy cheddar really puts that southern charm front and center. One reunion, I used mild cheese by accident and folks immediately noticed! No one beats sharp cheddar for extra flavor and that melt-in-your-mouth texture down South.
Keeping It Fresh
Keep any leftovers tightly covered for up to four days in the fridge. If you want to freeze it, just cut into portions and wrap them up tight. Pull a piece from the freezer whenever you want a quick hot lunch or dinner—let it thaw overnight, then heat in the oven or microwave until it’s good and hot.
Swap Stuff In
No chicken breasts? Shredded rotisserie chicken or some leftover turkey is perfect—and makes this even easier. Skip the meat and toss in mushrooms and extra peppers for a veggie twist. Switch up the cheese for Monterey Jack or pepper jack if you want something extra melty but less sharp.
Serving Ideas
I love piling a fresh green salad on the plate and maybe some crusty bread to soak up the cheesy sauce. Sometimes I’ll add in roasted asparagus or broccoli for something lighter. For parties, just cut it into small pieces for easy sharing, or serve over a scoop of rice if you want to stretch your servings a bit further.

Swap in cream of mushroom soup or go with homemade white sauce. Each one brings a bit of its own flavor and texture.

You bet! Put everything together the night before, store in the fridge, then bake when it’s time to eat. Super handy.
