A few quick notes
1. Stop at al dente
The spaghetti continues cooking in the oven, so drain it when just al dente during its first cooking stage.
2. Absorb the flour
Stir the flour thoroughly into the seasoned vegetables before adding broth, so no dry flour remains in the skillet.
3. Combine gently
Stir the sauce gently through the chicken and spaghetti in the baking dish before covering the top with the reserved cheese.
Get to know the ingredients
Cooked chicken
Start with cooked, chopped chicken breast. This bake heats it through with the pasta and sauce after everything is assembled.
Divided cheddar
One cup of cheddar melts into the sauce. Keep the remaining two cups separate for the top of the casserole.
Shredded carrot
Peel and shred the carrot before starting the sauce. It goes in with the broth after the flour is absorbed.

Review ingredients in your pantry before anything is added. Meal plans use your household size; grocery-only additions use the servings selected above.
The last little job
Look for bubbling
Bake until the casserole is hot and bubbly, then serve. The cheese topping should be melted over the creamy spaghetti beneath.
A little more help as you go
Broth and salt
Vegetable broth or salted chicken broth are allowed. With salted broth, wait to taste the thickened sauce before deciding on salt.
A little more heat
For a spicier bake, you can use one-eighth to one-quarter teaspoon of cayenne. The regular seasoning is described as mild.
A few questions you might have
Can I use cream instead of milk?
Yes. You can use cream in place of the milk when you want a richer flavor in the finished sauce.
Do the peppers need to soften first?
Cook both peppers and the onion in oil until softened, then add garlic and seasonings before building the flour-thickened sauce.
When does the milk go in?
Add it after the broth and carrot mixture thickens. Continue cooking until slightly thickened before melting in the first cup of cheese.
Can I add other vegetables?
You can use other vegetables. Sauté firmer vegetables with the peppers and onion, and add softer ones with the liquids.
Does the spaghetti go straight into the sauce skillet?
Put the cooked spaghetti and chicken in the baking dish, pour the sauce over them, then stir gently to combine.
Any more cooking tips?
Ingredients and Substitutions: Vegetables : this recipe is an easy one to add in your favorite vegetables or ones you need to use up. Simple sauté firmer veggies with the peppers and onions, and stir in soft veggies with the liquids. Broth : you can use vegetable broth or salted chicken broth if that’s what you have. If you are using salted broth, you may want to hold off on salting the sauce until it has thickened and you can taste it. Milk : feel free to swap the milk with cream for a richer flavor. Spice it up : this recipe has good flavor but is not spicy. Feel free to add a 1/8-¼ teaspoon of cayenne to bring the heat if that’s the way you like it!
