This bold Southern-inspired cheesy chicken spaghetti bake is what brings everyone running to the dinner table. It’s loaded with creamy cheesiness and just enough heat to keep things interesting—super comforting when you want dinner that feels like a hug, whether it’s a crazy weeknight or a chill potluck.
I came up with this after being bored with regular chicken casseroles. Tossed in cayenne for a punch and, just like that, it turned into a go-to Sunday supper at my place.
Mouthwatering Ingredients
- Green onions: Slice ‘em up for a zippy, fresh pop at the end just grab the crunchiest ones you find
- Garlic powder: Gives that earthy flavor, a quick sprinkle does the trick
- Cayenne pepper: Packs the heat add more if you like a sweat
- Paprika: A little smoky, a little sweet makes the flavor sing
- Cream of chicken soup: The creamy glue pick one with decent ingredients
- Fresh bell peppers: Bright sweetness and crunch use red, green, whatever’s on hand
- Shredded sharp cheddar cheese: Main cheesy hero, shred it fresh if you can
- Spaghetti: Soaks up the sauce stick with classic or use whole wheat
- Boneless skinless chicken breasts: Your protein got to be fresh so it stays juicy
Easy Step Guide
- Rest and Serve:
- Take out the casserole and wait five minutes so it’s easy to cut. Sprinkle green onions all over and serve while it’s hot.
- Assemble and Bake:
- Spread everything in the dish, smooth it out, top with the rest of the cheese, and bake till bubbling—about 25 to 30 minutes. That golden cheesy top is the best part.
- Mix the Casserole Base:
- In a huge bowl, throw in your shredded chicken, cooked noodles, soup, peppers, both spices, garlic powder, and half the cheese. Mix until it’s all one cozy mess.
- Boil the Spaghetti:
- Get salty water boiling. Drop in the pasta; cook till it’s just firm (8 to 10 min), then drain. Don’t let it get squishy—al dente’s key.
- Cook the Chicken:
- Set those chicken pieces in a heated pan. Let them brown—about 6–7 min per side. They should be cooked through and not pink anymore. Let cool a bit, then shred up.
- Prepare the Oven and Dish:
- Turn oven to 350°F and grease up a big casserole pan so cleanup’s a breeze.

I’m obsessed with sharp cheddar in this—its bold taste is what makes the whole dish pop. The creamy sauce and a spicy tingle just work. When I was a kid, my mom would hand me the cheese block to grate, and I always snuck a chunk or two. Fresh cheese always wins in this.
Leftover Storage
Got extras? Just wrap it up tight when cool and toss in the fridge—it’s still good for three days. The flavors get even cozier overnight. Heat it back up at 325°F in the oven with foil and the cheese stays ooey-gooey and the pasta doesn’t dry out.
Ingredient Swaps
No sharp cheddar? Go for Monterey Jack or pepper jack for more zing. Gluten-free noodles totally work! If you need more veggies, switch in diced poblanos or spinach. Rotisserie chicken is a great shortcut too.
Ways to Serve
Slice big squares and dish up with crisp salad and garlic bread. Want it wild? Spoon on salsa or add sour cream. Works as a brunch star at gatherings or as lunch leftovers the next day too!

Background & Traditions
Dishes like this in the South combine homey vibes and big taste. They got popular at potlucks and church suppers since you could fill everyone up with chicken, soup, and noodles. The hit of cayenne is a newer twist that keeps things lively.
Common Questions
- → Will this casserole turn out very spicy?
The heat level sits around mild to medium thanks to paprika and cayenne, but go ahead and use less (or more) cayenne if you want.
- → Is rotisserie chicken OK to use?
Sure thing! Rotisserie chicken is a time-saver and bumps up the taste. Just pull it apart and throw it in with everything else.
- → Got to use cheddar or can I switch it up?
Sharp cheddar's classic, but try Monterey Jack for extra meltiness or Pepper Jack if you want a bit more heat.
- → Could I get this prepped the day before?
Definitely. Put it all together in advance, stash it in the fridge, and bake later. It'll just need a tad longer in the oven if it's cold.
- → What if I want more veggies in there?
Go for it! Mushrooms, corn, or chopped tomatoes will all work. They'll add new colors and a bit more bite.
