Preheat your oven to 400 degrees Fahrenheit.
Open the Reynolds® Large Oven Bag and add 1 tablespoon of all-purpose flour.
Add the pasta, chicken, olive oil, lemon juice, lemon slices, salt, pepper, thyme, and water into the bag.
Seal the bag tightly and place it on a baking sheet.
Cut six 1/2-inch slits in the bag to let steam escape.
Bake in the preheated oven for about 30 minutes.
Remove the bag from the oven and squeeze out excess liquid through the steam slits.
Open the bag and add the parsley, stirring to combine.
Taste the dish and adjust seasoning if necessary.
Serve warm and enjoy!
