Leftover Casserole Supreme is perfect to use up holiday leftovers, or for any time of the year! It’s a versatile dish which can be created using a wide variety of meats. Whether you have leftover turkey, ham, or everyday chicken – with a few simple additives – you can create this simple, yet supreme, casserole.
This recipe is extremely versatile, you can add additional flour to create a larger amount for big families, and as long as you keep stirring, and are careful not to burn it, it’s extremely forgiving! Just don’t add more flour after you’ve added the milk, or you will have clumps. You can also substitute chicken, turkey, or beef broth instead of milk if desired. Keep adding liquid to the butter and flour, a little at a time, until you have a creamy consistency of medium thickness. Again, there is a wide margin for error here and it is subjective to your own preferences.
To begin – break leftover meat up into bite sized pieces and set them aside – this is a great job for even your youngest little chefs to help with. In the mean-time, begin boiling a pot of water to cook egg noodles or other pasta for your casserole.
Chop one large, or two small of your favorite onions, and grate 1 cup of cheese – Cheddar or Monterey Jack work well. Grate another 1/2 cup of cheese and set aside.
Place onion in another large skillet on medium heat with a teaspoon of butter, coconut, or olive oil. When onion cooks to almost translucent, add meat and stir. Season with a bit of garlic, pepper, and salt to taste.
Using a wooden spoon and a cast iron or other large skillet, add a big pat of butter (about 2 tablespoons) on medium heat and begin to stir. Slowly add in 2 tablespoons of flour, spelt, or gluten-free plain baking mix. Add another pat of butter, and another tablespoon of flour and mix, then add a splash of milk. Stir vigorously while adding a cup of milk and mix until mostly smooth. Add 1 cup of cheese and stir until melted and blended smoothly.
Cook the noodles as instructed on package and drain. Place pasta back into large pot. Add onion and meat mixture to pasta and stir. Pour cheese sauce over the top and stir.
Don’t be afraid to experiment with this dish by adding leftover vegetables like peas, corn, or broccoli.
Pre-heat oven to 350 degrees. Pour ingredients into casserole dish. Sprinkle additional 1/2 cup of cheese across the top, Add crunchy Durkey onions on top of the cheese and cook in the oven for about 15 minutes or until golden brown.
Leftover Casserole Supreme is a wonderful way to use up that leftover turkey or other meat after a big holiday celebration and will surely become a family favorite at your house, like it has in ours!
