This is a very easy sauce that has evolved over time. Allie makes it weekly for her family and it gets devoured. Allie loves that she can whip it up in less time than it takes to boil the pasta and it can be make with food she typically already has in her kitchen. Allie cheats a little in that she adds a jar of pre-made high quality marinara sauce to the meat. Allie serves the sauce over pasta (the current favorite in her house is Farfalli) with a simple tossed salad and a loaf of frozen garlic bread (like Pepperidge Farm).

This is a family favorite! Even our son Nick who is the pickiest of eaters devours what he affectionately calls Lemon Butt Chicken. I love to bring this to friends when I am helping with a meal train because it is so fast and easy to prepare and I deliver the uncooked meal to my friend and their home smells divine while the chicken is in the oven. It is an easy crowd pleaser and a meal we enjoy weekly.
