What You’ll Need

Here are the ingredients you’ll need to make white chicken spaghetti at home. See the recipe card located at the bottom of the post for full details.

  • Olive oil– You will use the olive oil to cook the chicken breast if using raw.
  • Chicken breast– I used raw chicken breast that I cubed. You can use a Rotisserie Chicken for an even quicker prep.
  • Italian Dressing dry mix– Find Italian dressing mix in the salad dressing isle of the grocery store.
  • Butter– For most of my recipes I use salted butter. Unsalted works just fine too.
  • Cream cheese– Use full-fat cream cheese for the recipe.
  • Heavy whipping cream– Heavy cream is used to make the alfredo sauce. No substitutions here.
  • Parmesan cheese– Use a good quality Parmesan Cheese for best tasting results.
  • Spaghetti noodles– I prefer a thin spaghetti noodle.
  • Shredded mozzarella cheese– Shredded mozzarella is melted on top of the spaghetti.
  • Fresh parsley– Fresh chopped parsley adds color and freshness to the dish.

Bake. Bake for 30-35 minutes until slightly golden brown. Remove and garnish with chopped fresh parsley if desired. Cut into squares and serve.

Can I Use Rotisserie Chicken Instead of Cook My Own?

Yes, if you don’t want to cook your own chicken breast cubes, rotisserie chicken works just fine. Don’t add the Italian Dressing seasoning to the Rotisserie chicken.

Recipe Tips For Success

  • Don’t Overcook Spaghetti. Keep a close eye on the spaghetti as it cooks. Check the doneness 2 minutes before the package suggests. Once al dente, remove immediately and drain. Keep in mind, the pasta will cook slightly more when it bakes.
  • Cook Alfedo Sauce On Low. When preparing the alfredo sauce, be sure heat is medium low. Stir often until cheeses are melted and smooth.
  • The Best Leftovers. This baked spaghetti makes great leftovers too. Enjoy!

    This was simple and delicious. I did make a few changes. I used Tyson Grilled Chicken Strips cubed in place of the raw breasts-I didn’t have raw on hand. I also added 3 T of minced onion, 3 T of minced bell peppers, and 2 minced garlic cloves to the skillet with the chicken and cooked about 5 minutes. I also had a handful of fresh baby spinach and about 1 c shredded carrots that needed using, so I tossed these into the pot to cook with the pasts. It was awesome and the easiest sauce recipe ever. Thanks for this.

    My family loved this dish. I got so many compliments. It was really good and a great dish for the fall. I didn’t have Italian dressing seasoning so I used a bit of garlic salt, pepper, and Italian seasoning. I may try to sneak some veggies in there next time

    My husband said this is the best thing I have ever made! I loved how easy it was to make and the alfredo sauce was better than any others I have tried! Husband and Kid approved!

    This was extremely yummy! I did everything exactly as you listed except I did use the 1/3 lower fat cream cheese, but other than that I followed your recipe. I was surprised by how little ingredients were used for the alfredo sauce. I’m used to making a béchamel with the flour and butter and whisking for no lumps. This was far easier and, with that salad dressing packet, extremely tasty! I also added broccoli into the dish before putting it into the oven. The kids, husband, and I all loved it! Will definitely be making this again! Thank you for, yet again, a delicious, kid-friendly recipe!

    Is there any substitute for the italian dressing packet as where i come from,there is none. I don’t even know what it is. Is it like a salad dressing or a soup powder?

    1. Jenny

      Hi Chamila, you can leave it out. I would substitute with 1/4 teaspoon kosher salt, 1/4 teaspoon freshly ground black pepper and 1/2 teaspoon dried Italian seasoning 🙂
