This creamy chicken pasta bake (made without cream!) is an easy recipe for leftover roast chicken and is loved by kids!

Ingredient notes and substitutions
Please scroll down to the recipe card at the end of the post for ingredient quantities.
- Chicken – leftover roast chicken (I’ve also made it with leftover baked chicken thighs) or rotisserie chicken.
- Broccoli – or substitute with cauliflower, sweetcorn or peas.
- Pasta – penne, rigatoni or macaroni are the best pasta shapes for a pasta bake.
- Sauce flavourings – a clove of garlic added to the sauce, along with a couple of sprigs of fresh thyme really elevate the flavour; however if don’t want to add them, this pasta bake still tastes amazing!
- Stock – chicken stock makes a rich béchamel sauce, substitute with vegetable stock, or use water for a less rich sauce.

How to make this chicken pasta bake recipe
Please scroll down to the recipe card at the end of the post for the full recipe.
- Cook the pasta and broccoli – make sure you use a large saucepan for this! Adding the broccoli to the last few minutes of the pasta cooking time saves on washing up.
- Make the béchamel – adding garlic and thyme really give this béchamel sauce a boost of flavour and creates a really rich creamy sauce without the need for cream. Add the liquid a little at a time, whisking well in between, to help prevent any lumps from forming.


- Add the cooked chicken – once the sauce is cooked, add the mustard and cheese, and then add the cooked chicken.
- Bake the pasta bake – combine the broccoli, pasta and sauce, top with mozzarella and bake until the cheese is bubbling and golden. Let the pasta bake stand for 5 minutes before serving. (It is very hot straight from the oven, but hard to resist!)



FAQ
I don’t recommend making this ahead as the pasta will absorb the sauce making the pasta bake dry. However you can make the béchamel sauce ahead (wait until assembling to add the chicken) and cook the pasta and store separately in the fridge.
Make sure you drain the pasta and broccoli well, otherwise this can create a watery pasta bake.
Yes – use gluten free pasta and gluten free flour.
Absolutely! Cut the raw chicken in to bitesize pieces and fry in 1 tablespoon olive oil for 7-10 minutes, until golden all over (it won’t be cooked through at this stage). Add to the sauce just before mixing with the broccoli and pasta, and bake as per the recipe.
Recipe Tip
- When I roast a chicken, I like to roast 2 chickens – it doesn’t take much longer and then I am left with some chicken to use over the next few days to make some easy dinners (and my favourite chicken mayo sandwich for lunch!). Some of my favourite easy leftover chicken recipes to use up the chicken include chicken and leek pie, leftover chicken curry, chicken and chorizo pasta and chicken pesto pasta salad.
Serving Ideas
This broccoli chicken pasta bake is delicious on it’s on, in a big bowl with a spoon; however if you want to serve extra veggies on the side then some peas or sweetcorn are always popular.
I personally love a salad with hot pasta! Somethings like a crunchy cabbage salad or rocket salad to balance out the richness!
