Chicken Biscuit Casserole

(ok so I am pretty sure I got this off of Rachel Ray's show, but can't quite remember...)

3 chicken breasts
7 tbsp butter
1 onion
2 tbsp flour
1 c chicken broth
1 c milk
dash of salt and pepper
3 garlic cloves
2 c baking mix
1/2 shredded cheddar cheese

preheat oven to 425 degrees

Shred or cut cooked chicken and put pieces on the bottom of a casserole dish.
In a skillet, melt 3 tbsp butter. Add onion. When onion is cooked, lower heat to medium and sprinkle flour into skillet. Stir in chicken broth, bring to a simmer, and cook until thick. Stir in 1/3 c milk and simmer 2 minutes. Pour into the casserole dish. (You can also add veggies to this recipe if you want).

Biscuits
Melt remaining butter with the garlic in a bowl in the microwave.
Stir baking mix and 2/3 c milk and cheese together in a bowl.
Drop tablespoonfuls of biscuit mix on top of casserole, then brush the biscuits with the butter-garlic mix.
Cover and bake until biscuits are golden, about 30 mins.

(you can cook it uncovered for slightly crispier biscuits)
