Baked Mushroom Chicken

I think I will cook this every night for dinner.....
4 large chicken breasts
1/4 cup flour
3T butter
1.5 cups sliced fresh mushrooms
3/4 cup chicken broth
salt & pepper
1/3 cup grated mozzarella(or more)(be generous)
1/3 cup grated parmesan (or more)(be generous)
1/4 cup sliced green onions
Pound out the chicken breasts between plastic wrap. I sliced each one in half horizontally to make 8 breasts because they were thick. If using already thin ones, double the breasts. Make them 1/4" thick. Salt and pepper them, then dredge in flour. Brown over med-high heat in butter. Add oil to butter if burning. Place browned chicken in large casserole dish. Meanwhile, in 1-2T butter, sautee mushrooms till darker and yummy. Add salt and little pepper and chicken broth. (you may want to double chicken broth if using more breasts.) Boil 5 mins till liquid is reduced to 1/2 cup. Pour mushrooms over chicken, and bake 15-20 minutes @375. Take out and top with cheeses and green onions. Bake another 5-6 mins till melted. I served this over cooked egg noodles tossed with butter, parsley flakes and salt. WAY GOOD.
