Step 1

Preheat oven to 350 degrees F.

Step 2

Add the flour to a bowl; then dredge the chicken in the flour and place on a plate until all pieces have been coated.

Step 3

Heat the butter and oil in a large nonstick skillet over medium high heat. When the pan is hot enough, add the chicken and cook 2-3 minutes per side until they become lightly browned.

Step 4

Place the cooked chicken directly into an oven safe baking dish; then repeat until all of the chicken is cooked through.

Step 5

Add the mushrooms, scallions, thyme and garlic to the pan; then cook until the mushrooms have softened; approximately 1-2 minutes.

Step 6

Next, add flour, stir well; then add the champagne and stir until the sauce thickens slightly.

Step 7

Pour the mixture over the chicken; then bake for 15-20 minutes until hot and bubbly. (This ensures the chicken is cooked through).
