Tender chicken and spaghetti tossed in a creamy cheese sauce with a kick of green chiles, all baked until golden and bubbly under a blanket of melted cheddar.
Preheat your oven to 350 F (175 C) and lightly grease a 9x13-inch baking dish with butter or cooking spray.
Bring a large pot of salted water to a boil. Break the spaghetti in half, add it to the water, and cook 1 to 2 minutes less than the package directions so it stays firm (about 8 minutes). Drain well and set aside.
While the pasta cooks, melt the butter in a large skillet over medium heat. Add the onion and bell pepper and cook, stirring often, for 5 to 6 minutes until softened and translucent. Stir in the garlic and cook 30 seconds more until fragrant.
Reduce the heat to medium-low and stir in the cream of chicken soup, diced tomatoes with green chiles (with their juice), and chicken broth. Whisk until smooth and let it warm through for 2 to 3 minutes.
Turn off the heat and stir in the sour cream, 1 1/2 cups of the cheddar, garlic powder, black pepper, and salt until the cheese melts into a smooth, creamy sauce.
Add the cooked chicken and drained spaghetti to the skillet (or combine everything in the pot). Toss gently with tongs until every strand is coated in sauce. Taste and add more salt if needed.
Transfer the mixture to the prepared baking dish and spread it into an even layer. Scatter the remaining 1 cup of cheddar evenly over the top.
Bake uncovered for 25 to 30 minutes, until the casserole is bubbling around the edges and the cheese on top is fully melted and just starting to turn golden.
For a browner, crispier top, switch the oven to broil for the last 2 to 3 minutes, watching closely so it does not burn.
Let the casserole rest for 5 to 10 minutes before serving so the sauce can set. Serve warm.

This is the comforting original: tender shredded chicken and spaghetti folded into a creamy mushroom sauce, then blanketed with cheddar and baked until bubbly. It comes together with pantry staples and pleases picky eaters every time. For extra richness, stir a splash of milk into the sauce before it goes in the oven so the noodles stay silky.
A Southern potluck favorite that layers spaghetti and chicken with a zesty tomato-and-green-chile sauce and plenty of melty cheese. The Rotel adds a gentle kick and keeps every bite bright and saucy. Drain the tomatoes just slightly if you like a thicker, sliceable casserole.
For game-day cravings, this bake tosses spaghetti and chicken in tangy buffalo sauce, then finishes with ranch drizzle and a cool crumble of blue cheese. It delivers all the wing-night flavor in a fork-friendly dish. Adjust the hot sauce to taste and add a little melted butter to round out the heat.
This Tex-Mex twist swaps in a creamy sauce spiked with cumin, chili powder, and tomatoes for a bold, layered casserole. Corn and bell peppers add sweetness and color between the noodles and cheese. Top with crushed tortilla chips in the last ten minutes for a crunchy, golden finish.
Smoky andouille-style seasoning and a splash of cream turn this into a lively, Louisiana-inspired casserole full of peppers and onions. The spice builds gently and pairs beautifully with the tender chicken and pasta. A handful of sliced smoked sausage stirred in makes it extra hearty for a hungry crowd.
Rich Alfredo sauce coats spaghetti and chicken in this indulgent, restaurant-style bake finished with mozzarella and Parmesan. It is creamy, garlicky, and deeply satisfying on a cold night. Fold in steamed broccoli or spinach for a pop of green and a little balance to the richness.
This crowd-pleaser hides a luscious cream cheese and sour cream layer between the noodles for an extra-decadent middle. The tangy filling melts into the chicken and pasta as it bakes, tasting far fancier than the effort suggests. Spread the cream layer edge to edge so every serving gets that signature ribbon.
All the flavor of chicken parm reimagined as a baked spaghetti casserole with marinara, mozzarella, and crispy seasoned breadcrumbs on top. It is saucy underneath and golden and crunchy above. Use breaded chicken cutlets, cut into strips, if you want that true chicken-parm bite in every forkful.
Bright basil pesto tossed with spaghetti and chicken makes a fresh, herby casserole that feels lighter than the creamy versions. Melted mozzarella and cherry tomatoes on top add color and a little sweetness. A squeeze of lemon just before serving keeps the flavors vibrant and green.
This bake borrows from everyone's favorite party dip, folding creamy spinach, artichokes, and Parmesan through the chicken and noodles. It is rich, savory, and a sneaky way to get some greens on the table. Squeeze the spinach dry first so the casserole stays creamy instead of watery.
Smoky bacon, cool ranch seasoning, and gooey cheddar turn this into an irresistible weeknight winner. The trio of flavors clings to every strand of spaghetti and chicken for a bite that keeps everyone coming back. Reserve some crumbled bacon for the top so it stays crisp against the creamy noodles.
A lighter, tomato-forward casserole built on a garlicky marinara with fresh basil and just enough mozzarella to bind it. It tastes fresh and homey without the heaviness of a cream sauce. Stir in a spoonful of ricotta for little pockets of creaminess without weighing it down.
Roasted green chiles and Monterey Jack give this Southwest casserole a mellow, smoky warmth that is comforting rather than fiery. The creamy chile sauce coats the chicken and pasta beautifully. Char a fresh poblano and chop it in for an even deeper roasted flavor.
This timeless bake folds chicken and spaghetti into a creamy sherry-kissed mushroom sauce topped with Parmesan and buttery breadcrumbs. It is elegant enough for company yet easy enough for a Tuesday. A pinch of nutmeg in the sauce adds a subtle warmth that makes it taste truly special.
Cream cheese, cheddar, bacon, and diced jalapenos bring all the popper flavor to this crowd-pleasing casserole. It is creamy, cheesy, and pleasantly spicy in every bite. Remove the jalapeno seeds for a milder version, or leave a few in for those who like real heat.
Bright lemon and plenty of garlic lift this lighter casserole away from the usual heavy creaminess. A little butter and Parmesan tie the chicken and noodles together without overwhelming them. Finish with fresh parsley and lemon zest for a fragrant, fresh-tasting dinner.
Tender broccoli florets and sharp cheddar make this a comforting one-dish meal that sneaks in vegetables the whole family will eat. The cheesy sauce clings to the noodles, chicken, and broccoli alike. Blanch the broccoli briefly first so it keeps a little bite instead of turning soft in the oven.
Tangy sun-dried tomatoes and a touch of cream give this bake a rich, slightly sweet Mediterranean flavor. Spinach and Parmesan round it out into something a little more grown-up. Use a spoonful of the oil from the tomato jar to saute the garlic for extra depth.
Tangy tomatillo salsa verde and Monterey Jack turn this into a zesty, saucy casserole with real south-of-the-border character. The bright, slightly tart sauce keeps every bite lively. Top with crushed tortilla chips and a scatter of cilantro just before serving for texture and freshness.
Deeply caramelized onions and nutty Gruyere give this casserole the cozy, savory soul of French onion soup. The sweet onions melt into the sauce and coat the chicken and noodles beautifully. Take your time caramelizing the onions low and slow, since that patience is what makes this dish sing.
