There a couple of ways to prepare the chicken. You can cook it the night before in the crockpot, or by boiling the chicken. The way I’ve been doing it lately is the lazy way. I buy the deboned rotisserie chicken at Costco. It has been such a time saver for recipes like this. That being said, you could use rotisserie chicken as well.

How to Make Chicken Rotini
- Cook rotini pasta using package directions until tender. Drain.
- Add butter to a saucepan over medium heat. Once melted add diced peppers. Cook until tender.
- Add flour to peppers and stir. Over medium heat, add half and half and chicken broth. (Made with water and chicken bouillon.). Add seasonings and stir. Bring to boil and let simmer until thick.
- In a large pan, combine rotini, sauce, and chicken. Add parmesan cheese and stir. Top with additional parmesan cheese. Add to the baking dish and bake for 30 minutes at 350˚ F. Serve warm.
This chicken rotini is delicious comfort food. It was a big hit with my family as I’m sure it will be with yours.

Chicken Rotini Tips and Techniques:
Freezer Cooking: If making this for the freezer. Complete all directions except for baking and freeze in well covered baking dish. When ready to enjoy, let thaw overnight in the refrigerator and bake as directed.
Thick Sauce Tips: It’s really important to let the flour really soak into the peppers before you add the half and half and chicken broth. You are creating a roux that will bring a flavorful sauce. Let thicken before adding to other ingredients. It will take about 10 minutes of simmering over medium heat. Stir constantly as you don’t want the milk to overboil and spill over your pan.
Chicken Broth: I highly recommend Better than Bouillon to make your chicken broth. I keep mine in the refrigerator ready to use whenever I need it!

I just tried this out because I was looking for easy freezer meals for my order of Zaycon chicken.
Turned out great! I ended up adding some fresh minced garlic and red onion to the sauce and a little salt and pepper to taste and it was sooooo good! Bought a bunch of foil loaf type pans from dollar tree and stashed away 6 of them in the freezer. Thanks for the great recipe!!!
Hi! If I used 2 cups chicken broth , do I omit the 2 cups of water?
Yes, you only want 2 cups of liquid. The 2 cups of water with the Chicken Bouillon are the same as 2 cups of chicken broth.
