Chicken in Creamy Parmesan Gravy

I found a recipe for this online but made a few changes. It's one of our new favorites and comes together super quick.

6-8 chicken tenders
2 T. butter
salt & pepper
garlic (fresh or garlic salt)
parsley (I have a garlic/parsley blend I use and love)
minced onion (to taste)
dried basil
3 T. flour
2 1/2 c. chicken broth
1/2 c. milk
1/2 c. parmesan

Melt 2 T. butter in a large saucepan. Add salt and pepper, then add chicken. Brown on both sides, then remove chicken. Add all seasonings and 3 T. flour. I just shake in garlic, parsley, basil, salt and pepper until it looks and smells right. :) Whisk together until it bubbles, then whisk in chicken broth until smooth. Add chicken back in and simmer for 10 minutes. It should be pretty thick and the chicken should be cooked completely. Add 1/2 c. milk and 1/2 c. parmesan and continue to simmer until it's creamy and thick enough to your taste. Serve over mashed potatoes or rice.
