How to Make this Cheesy Homestyle Chicken Spaghetti Casserole
Making this comforting chicken spaghetti casserole starts with preparing your pasta and chicken. Begin by breaking 1 pound of spaghetti into halves or thirds—this makes it much easier to stir and serve later (nobody wants to wrangle those long noodles on their plate). While your pasta cooks to al dente, boil 5 chicken breasts until they’re thoroughly cooked, then cut them into bite-sized pieces. Remember, you could substitute chicken thighs if that’s what you have on hand. Dark meat actually adds more flavor, if we’re being honest.
Once your pasta is drained and your chicken is ready, it’s time to create that creamy, flavorful base. In a large bowl, combine 2 cans of cream of mushroom soup, 2 cans of Rotel tomatoes (these add just the right amount of spice), 1 cup of chicken broth, and 2 packages of McCormick’s spaghetti sauce mix. Season the mixture with 1 teaspoon of garlic salt and 1/2 teaspoon of pepper. Now fold in 1/3 cup of chopped green pepper and 1/2 cup of chopped onion—though adding more vegetables never hurts, and red bell pepper makes a colorful addition. For best results, prepare this dish using a quality stainless steel cookware that distributes heat evenly. Gently mix your cooked spaghetti and chicken pieces into this savory sauce until everything is well-coated.
Transfer this mixture to a large, greased baking dish, spreading it evenly. The final touch before baking? Sprinkle 1 cup of cheddar cheese over the top—this creates that irresistible golden, bubbly crust we’re all looking forward to. Cover the dish with foil and bake at 350°F for 45 minutes. Then, remove the foil and continue baking for another 15 minutes until the cheese is perfectly melted and slightly browned. The contrast between the creamy interior and the crispy cheese top is what makes this casserole truly special.
Cheesy Homestyle Chicken Spaghetti Casserole Substitutions and Variations
While the classic version of this chicken spaghetti casserole is absolutely delicious, you don’t need to feel locked into the exact ingredient list. Let’s talk substitutions, shall we? For a lighter version, swap the cream of mushroom soup with Greek yogurt mixed with chicken broth. Not a fan of spicy? Replace Rotel tomatoes with regular diced tomatoes.
The cheese is totally customizable too. Monterey Jack, pepper jack, or a Mexican blend can replace the cheddar for different flavor profiles. Vegetarians in the family? Substitute mushrooms and extra bell peppers for the chicken.
Can’t find McCormick’s spaghetti sauce mix? No problem. Use Italian seasoning, garlic powder, and a pinch of red pepper flakes instead. The beauty of this casserole is its flexibility—perfect for using what you’ve already got in your pantry.
What to Serve with Cheesy Homestyle Chicken Spaghetti Casserole
So what goes well with a bubbling dish of cheesy chicken spaghetti? I always think a simple green salad with a light vinaigrette creates the perfect balance to this rich casserole. The crisp vegetables and tangy dressing cut through all that delicious cheese and pasta.
Garlic bread is another no-brainer pairing, perfect for sopping up any extra sauce left on your plate. Can you imagine that buttery, toasted bread with a bit of the cheesy sauce? Divine.
For vegetables, I’d suggest either roasted broccoli or sautéed green beans to add some color and nutrition to your plate. During summer months, grilled zucchini or yellow squash works beautifully too. Remember, the goal is something fresh to complement your hearty main dish.
Final Thoughts
This cheesy chicken spaghetti casserole has become my go-to comfort food recipe whenever I need something hearty and satisfying that’ll please the whole family.

I love how versatile this recipe is, too. Don’t have green peppers? Red ones work just fine. Want it spicier? Add extra Rotel tomatoes. The beauty of comfort food is making it your own.
