My Good Life -

Ingredients
4 boneless, skinless chicken breasts
4 tablespoons butter
2 cloves garlic, minced
1 small red onion, chopped
3/4 cup chicken broth
6 tbsp. white wine or vermouth
1 tbsp. flour
salt and pepper
1 cup diced tomatoes, well drained
1 tbsp. fresh thyme (or 1 tsp. dried)
12 oz fresh mushrooms, sliced

Method
Melt butter in a large skillet, then add chicken breasts and sear on each side until lightly browned, about five minutes on each side.

Remove chicken and set aside. Add garlic and onions to pan and cook for a few minutes, just until softened; turn off heat.

In the crock of your slow cooker, whisk together broth, wine, flour, salt, and pepper until well blended. Stir in the contents of the saute pan, including any remaining  butter. Add the rest of the ingredients and mix well.

Lay the chicken breasts on top of the mixture and cook on low for 2-3 hours or high for 1-1 1/2 hours, until chicken is cooked through.

Remove the lid about 20 minutes before serving if you would like to further reduce the sauce.
