Chicken Marsala with Portobello Mushrooms

Step 1
Preheat oven to 350 degrees F (175 degrees C).

Step 2
Melt 4 tablespoons butter and heat 1 tablespoon olive oil in a skillet over medium heat. Cook and stir the mushroom slices in the skillet until tender. Remove pan from heat and set aside.

Step 3
Melt 1 tablespoon butter and heat 1 tablespoon olive oil in a saucepan over medium-high heat. Stir in the garlic and cook until tender, then gradually whisk in 1 tablespoon flour. Cook, stirring constantly, for 1 minute.

Step 4
Increase heat to high, and whisk in the beef broth, Marsala, and browning sauce. Season sauce with 1/2 teaspoon salt and 1/4 teaspoon pepper. Bring sauce to a boil, and reduce heat to low. Mix in the cooked mushrooms; you'll use the skillet to cook the chicken. Cover saucepan and remove from heat.

Step 5
Season chicken with salt and pepper, and dredge chicken breasts in the flour. Over medium heat, melt remaining 3 tablespoons butter in the skillet used to cook the mushrooms. Cook the chicken 2 minutes per side, until browned. Arrange the chicken in the bottom of a 9×13 inch baking dish, and cover with the sauce and mushroom mixture.

Step 6
Cover baking dish, and bake 25 minutes in the preheated oven, or until chicken juices run clear.
