Step 3

Combine the seasonings in a small bowl. Rub evenly over the chicken breast.

Step 4

Warm a skillet over medium-high heat. Add the olive oil to the pan. Once hot, cook the chicken for 4 minutes per side. Remove from heat and set aside. Saute the mushrooms in the remaining oil for about 5 minutes until tender.

Step 5

Prepare a 9x13-inch baking dish by lightly greasing with olive oil or cooking spray. Transfer a small portion of the sauce and spread over the center of the pan. The corners don’t matter, but do add enough to fill the entire space under the chicken.

Step 6

Finally, divide the remaining sauce and cover evenly.

Step 7

Bake for about 15 minutes or until the internal temperature reaches 165 °F. Once done, the cheese will be completely melted, and the chicken cooked through. Add green onion garnish and serve warm.
