Baked Chicken Spaghetti recipe

Ingredients

  • 1 pound cooked spaghetti (break those noodles for ultimate scoop-ability)
  • 2 cans (10 3/4 ounces each) cream of mushroom soup
  • 2 cans (10 ounces each) original Rotel tomatoes
  • 1 cup chicken broth
  • 2 packages (1 3/8 ounces each) McCormick’s spaghetti sauce mix (dry, in envelopes—not the jarred stuff)
  • 1 teaspoon garlic salt
  • 1/2 teaspoon pepper
  • 1/3 cup chopped green pepper (but hey, toss in more if you’re feeling wild—red bell pepper fits right in)
  • 1/2 cup chopped onion (or go crazy, bump it up to 3/4 cup)
  • 1 cup cheddar cheese (the sharp kind makes everything better, but mild’s fine too)
  • 5 chicken breasts, boiled and cut into bite-sized chunks (thighs are welcome to the party, too)

Steps

  1. Preheat your oven to 350 degrees. Trust me, do this first unless you love waiting around.
  2. Bring a big pot of water to a boil and toss in 1 pound of spaghetti, broken in half or thirds. Makes for easier scooping later—less noodle slap, more noodle scoop.
  3. Boil the spaghetti until it’s just tender, then drain well. No one likes watery casserole.
  4. In a huge mixing bowl, combine the cooked spaghetti, 2 cans of cream of mushroom soup (10 3/4 ounces each), 2 cans of original Rotel tomatoes (10 ounces each), and 1 cup chicken broth. This is where the magic starts.
  5. Add 2 packets of McCormick’s spaghetti sauce mix (1 3/8 ounces each—yes, those little dry envelopes). Rip them open like a pro.
  6. Sprinkle in 1 teaspoon garlic salt and 1/2 teaspoon pepper. Use the measuring spoons if you must, but “eyeballing” is a time-honored tradition.
  7. Toss in 1/3 cup chopped green pepper (or more if your fridge is begging you to use that red bell pepper too).
  8. Add 1/2 cup chopped onion—unless you’re feeling wild, then go for 3/4 cup. Onion math is a thing.
  9. Plop in 5 chicken breasts, boiled and cut into bite-sized pieces. Or swap in some thighs if you’re feeling rebellious. Give everything a good mix. This is arm workout territory.
  10. Grab your largest baking dish and spray it with nonstick spray. Unless you enjoy chiseling baked cheese off glassware. I do not.
  11. Spread that glorious chicken-spaghetti mixture evenly in the pan. Make it look fancy, or don’t. The cheese is coming to save the day.
  12. Sprinkle 1 cup of cheddar cheese over the top. Sharp, mild, whatever makes your heart sing. Just make it rain cheese.
  13. Cover the dish with foil. Into the oven it goes for 45 minutes. This is the perfect window to contemplate life or clean up the kitchen. Or scroll your phone. No judgment.
  14. After 45 minutes, yank off the foil (carefully—steam facial, anyone?) and bake uncovered for another 15 minutes. This is how you get that golden, bubbly cheese top.
  15. Pull the bubbling masterpiece out, let it cool for a few minutes so you don’t burn your tongue in your eagerness, and serve up big, cheesy scoops. Leftovers? Even better tomorrow. Or later tonight. Midnight fridge raids are totally valid.

Dutch ovens are a classic cookware favorite that work great for slow-cooked dishes and casseroles like this one—consider using a Dutch oven if you want even heating and easy transfer from stovetop to oven. A small smokeless indoor grill can also be handy for searing chicken before adding it to casseroles if you want a bit of extra char and less smoke indoors.

Also, if you’re serving at a party, a candy making machine can be a fun countertop attraction to pair with dessert—guests love interactive treats.

Cooking Tips

Ever wonder how to make your baked chicken spaghetti truly unforgettable? I always recommend using freshly shredded cheddar for that irresistible golden crust. Sautéing onions and peppers until fragrant deepens the flavor profile. Let your baked spaghetti rest for a few minutes after baking—this allows the sauce to set, creating perfect slices. Don’t forget to season generously for a savory, mouthwatering chicken spaghetti experience.

Final Thoughts

Once you’ve layered in those little touches—like freshly grated cheddar and perfectly sautéed vegetables—the baked chicken spaghetti emerges from the oven bubbling and golden, filling the kitchen with a savory aroma that’s impossible to resist. I savor the creamy sauce binding every strand of pasta, the hint of spice from Rotel, and the rich, melty cheese. This dish always brings comfort and a sense of home.
