Here is my very favorite chicken florentine recipe. A creamy topping and pretty presentation make it elegant enough for company, but it’s also fast to fix on busy weeknights! —Julie Fitzgerald, St Louis, Missouri
Flatten chicken to 1/2-in. thickness. In a large resealable plastic bag, combine the Parmesan cheese, basil and oregano. Add chicken, a few pieces at a time, and shake to coat.
In a large skillet over medium heat, cook chicken in 2 tablespoons butter for 4-5 minutes on each side or until a thermometer reads 170°. Remove and keep warm.
In the same skillet, saute onions in remaining butter for 2-3 minutes or until tender. Add garlic; cook 1 minute longer. Gradually add flour and salt; stir in milk and sherry or broth until blended.
Bring to a boil. Reduce heat; cook and stir for 1-2 minutes or until thickened. Stir in spinach and pimientos; heat through.
Remove from the heat. Stir in sour cream until blended. Spoon over chicken; sprinkle with mozzarella cheese.
