Mouthwatering Southern chicken spaghetti stuffed with gooey cheese always hits the spot when you're in the mood for a spicy treat. It's made with basic stuff you probably already have, and the bold flavors make it a weeknight favorite that brings everyone to the table craving another helping.
The first time I shared this at a family potluck it vanished before I blinked – now my relatives beg for it every holiday. It's become a steady part of our Sunday dinners and even folks who don't normally like spicy stuff end up loving it.
Irresistible Ingredients
- Cream of chicken soup: Adds creamy goodness and ties everything together, use the low-sodium kind if that's your jam
- Fresh bell peppers: Crunchy and sweet, pick the firm, shiny ones for the best taste
- Cayenne pepper: The stuff that brings the spicy punch – adjust to how much heat you want, and fresh ground gives the best kick
- Shredded sharp cheddar cheese: Packs a tangy punch and melts down dreamy, grate your own for super melty magic
- Boneless skinless chicken breasts: These soak up all the flavors, make sure they're fresh for juicy bites
- Garlic powder: Gives a tasty background flavor, use recently bought powder for max flavor
- Green onions: Sliced up crisp tops add a fresh vibe at the end
- Spaghetti: Helps catch all that creamy sauce, regular or wheat works great for extra fiber
- Paprika: Sweet, smoky depth – aim for a vibrant red for the most flavor
Easy How-To Steps
- Finish and Serve:
- Let the cheesy goodness cool about 5 minutes so you can slice it neatly and sprinkle on those green onions. Cut up and dig in – you'll keep your tongue safe, too!
- Bake Time:
- Pop that dish into a piping hot 350 oven for around 25 to 30 minutes. You'll know it's ready when you see the edges bubbling and the cheese browned up just right.
- Ready the Casserole:
- Rub a little oil or butter inside a big baking dish, spread the spaghetti mix in, and layer on whatever cheese is left. It’ll melt into a bubbly cover of gold.
- Get the Filling Mixed:
- Combine shredded chicken, cooked spaghetti, your bell peppers, the soup, seasonings, and half the cheese in a big bowl. Stir everything up gentle so every bite gets some love.
- Make the Pasta:
- Boil a salted pot of water, toss in spaghetti and cook till chewy but not mushy – about 8 to 10 min. Drain and skip rinsing so it all sticks together later.
- Cook Chicken:
- Start with chicken breasts in a pot over medium fire – give each side 6 to 7 minutes. They should turn nicely golden and clear through. Let 'em rest a bit and then shred with forks. That way, juices stay in.

The sharp cheddar's really the star for me – it gives each bite that punchy Southern taste that just wakes up the whole table. One year I used sharper cheese for a change and everyone snatched seconds before I could even sit down. More cheddar always shouts Southern comfort!
Storing Leftovers the Easy Way
Leftover slices stay fresh in a sealed container for up to 4 days. You can also freeze them – just slice and wrap each piece then stash away. Later, grab a chunk, thaw it, and reheat in your oven or zap it in the microwave till it's hot and gooey again.
Handy Ingredient Swaps
Out of chicken breasts? Rotisserie chicken or leftover turkey brings awesome flavor and saves you time, too. Wanna keep it meat-free? Sautéed mushrooms and more peppers bulk it up just fine. If sharp cheddar's too bold, try mellow Monterey Jack or zesty pepper jack for some cheesy love without the sharp bite.
Fun Serving Ideas
This spicy favorite plays well with fresh salads and crunchy bread to make a full meal. Sometimes I toss in roasted veggies like broccoli or asparagus to keep it lighter. For get-togethers, just cut into neat squares to serve, or spoon over steamed rice if you want to make it last longer.

Southern Heritage
This dish is all about Southern warmth, wrapping up creamy flavors with a little fire for excitement. In the south, sharing a bubbling casserole is just another way to say welcome. Back in the day, spaghetti casseroles popped up to stretch ingredients and shake up family dinners during busy weeks.
