How to make Creamy Chicken Spaghetti
Be sure to see the recipe card below for full ingredients & instructions!
- Cook Spaghetti: Make the pasta according to package instructions until al dente, and set aside.
- Make Creamy Cheese Sauce: In a large skillet, cook the garlic and bell pepper, then stir in the flour and Italian seasoning. Add in the cream, broth and milk then bring to a boil. Remove form the heat and add the mozzarella, stir until melted.
- Combine Ingredients: Stir in the shredded chicken, cooked spaghetti, and tomatoes.
- Bake: In a baking dish spread the chicken spaghetti and top with the cheese sauce, bake until fully heated through.
Once all the ingredients are cooked up and combined in the casserole dish, it only takes about 20 minutes to bake. It just needs to warm through and melt all of the cheese.
Yes! Skip the bell peppers if you like, or add veggies you have on hand. Diced onions, zucchini, and mushrooms would all taste great.
Store leftovers in an airtight container, and they will last in the fridge 3-5 days.
Serving Suggestions
This baked chicken spaghetti is definitely a whole meal in itself. But I also love serving it with some cheesy garlic bread, and maybe a side salad.
This recipe is a really pantry friendly meal–you’ll likely have most ingredients already in your kitchen. Prep time is 10 mins and you can throw it in the oven and let that chicken casserole bake to perfection!
Recipe Tips and Notes
- Make sure to use enough water to cook the pasta, so that when the pasta expands, there’s room for the noodles to move freely.
- If freezing, line your dish with parchment paper and let it freeze solid, then transfer to a large freezer bag. This frees up your casserole dish.
- You can make this with other pastas that you have on hand.
What makes this chicken spaghetti so creamy?
The secret ingredient? We use heavy cream in this recipe!
A combination of heavy whipping cream, chicken broth, and milk creates a super creamy, rich pasta sauce that bakes in nicely. It adds a lot of moisture and tastes beautifully rich.
Can I use a different pasta?
Yes, of course! You can use any type of spaghetti or long noodles, like fettuccine or angel hair pasta. Or you can substitute the spaghetti with medium shells, macaroni or small round pasta noodles. It all comes out so well in this baked pasta recipe. Just make sure to follow the pasta box instructions to cook before adding into the dish.
Can I freeze chicken spaghetti?
This creamy chicken spaghetti freezes really well, so you can make it in advance or pop leftovers in the freezer.
If you’re making it to freeze, skip the baking. Follow the instructions and place it in the casserole dish, then let it cool and freeze for up to four months. You can then cook this cheesy chicken spaghetti recipe directly from frozen.
This deliciously cheesy, creamy chicken spaghetti bake in just so perfect for weeknight dinners. It’s easy and quick to make, leftovers keep well, and the whole family will love it!

Can I sub half and half for the heavy cream? And can I use skim milk?
Becky Hardin says
Yes, you can use half and half and any milk you have on hand. Skim should work just fine!

Jomoco says
I tried the creamy chicken spaghetti recipe. I used frozen precooked grilled chicken strips, cream of mushroom soup, mozzarella and sharp cheddar, onion powder, chicken bouillon, and all the other ingredients the recipe called for except the regular milk. I enjoyed making it, will probably adjust the seasonings to taste and do it again if it tastes good to me and family.

I’m happy to hear you enjoyed it!
