Optional:salsa, sour cream, and additional green onions for serving
Instructions
Preheat oven to 350℉ and spray a 9x13 inch baking dish with cooking spray. In a medium bowl, stir together ham, green onions and 2 cups of cheese (save the remaining 1/2 cup for later).
Use a 1/2-cup measuring cup to scoop out cheese mixture onto a tortilla. Roll up tortilla and place seam side down in the baking dish. Roll up all tortillas and place them into the baking dish with the sides touching.
In a medium bowl, Whisk together half-and-half, eggs, flour, and salt. Pour over tortillas. If making ahead of time, cover and refrigerate overnight, otherwise continue to bake.
Bake covered for 30-40 minutes. Remove foil and sprinkle remaining 1/2 cup of cheese over enchiladas. Bake for 10 more minutes or until tops are golden brown and the egg mixture is set.
Serve plain or with salsa, sour cream, and additional green onions.
