Recipe ingredients

One of the best things about this leftover chicken pasta bake is that it uses many ingredients that you probably already have in the house (pasta, bacon, canned mushrooms).
Leftover chicken: I always make this chicken pasta bake when I have leftover chicken, either from making chicken soup with dumplings or from making whole roast chicken. You can also use rotisserie chicken or leftover turkey.
Bacon: I used slightly smoked, very lean bacon cubes, but you can use regular bacon slices instead, whatever you have. Try this Chicken Orzo Bake with bacon, too.
Mushrooms: I had a jar of mushrooms lying around in the pantry, so I drained the mushrooms and added them to the pasta mixture. Fresh mushrooms are great, too, but you have to cook them first.

- Mushrooms: If using fresh mushrooms, clean them with kitchen paper, slice them thinly, and fry them in the pan you used for frying the bacon for about 3-4 minutes, until the water they release evaporates and they are golden. You will not need to add fat if there is still some bacon fat in the pan.If using mushrooms from a jar, let them drain well.1 can/jar of mushrooms or 9 oz/ 250 g fresh mushrooms

- Use leftover chicken (or turkey) or use rotisserie chicken. If none is available, cook about the same amount of chicken breast and use that instead.
- Cheese: Gouda, Cheddar, or any kind of cheese you like to use when making pasta bakes.
