Chop the cooked leftover turkey into bite sized pieces. Add to a large bowl. If you are using ground turkey, cook in a skillet and break up in to bite sized pieces.
Chop the onions and mince the garlic. Add 1Tbsp of butter to a hot pan then add the onions, garlic, mushrooms and celery. Cook for 8-10 minutes until the mushrooms shrink in size and the onions are translucent. Add to the bowl of turkey.
Make the cream sauce by adding 2 Tbsp of butter to the empty skillet and adding 1 Tbsp of flour(cassava flour for gf) to make the roux. Cook the roux to cook out the raw flour taste, this should just take a few minutes, the roux will start to change color to a deeper color.
Add the cream, wine and broth to the roux and mix. Allow to gently simmer until the sauce has reduced and the roux has sufficiently thickened the sauce to a creamy gravy consistency.
Add the fresh parsley, thyme, nutmeg and cracked black pepper.
Cook the egg noodles per instructions, then strain and add to the bowl of turkey and veggies.
Pour the sauce over the noodles, turkey and veggies and mix thoroughly.
Transfer everything to a large casserole pan and top with bread crumbs. Stick under the broiler until the top is golden brown and forms a crust. For gluten-free bread crumbs add some melted butter to them and place them over the top wet as they don’t work the same as regular bread crumbs.
Sprinkle more fresh parsley and cracked black pepper on top. I add some optional crushed red pepper flakes on top and a garnish of fresh thyme sprigs.
