Step 1

Season chicken with salt and pepper and dredge both sides in flour.

Heat 3 tablespoons oil in a large skillet over medium/high heat. Once oil is hot, add chicken and sauté until golden. Work in batches if needed so you don't crowd your pan. Don't worry about cooking the chicken through; it still needs to go in the oven. Transfer chicken to a 13x9 casserole baking dish.

Wipe down the skillet with a paper towel. Add 3 tablespoons oil along with sliced mushrooms and diced onions and sauté until soft and golden. Add garlic and sauté another 1 to 2 minutes.

Spread mixture over the chicken.

In a medium saucepan (or in the same pan you've been using), melt 3 tablespoons butter. Whisk in 3 tablespoons flour until lightly golden (1 - 2 minutes).

Add 1½ cups chicken broth, 1 tablespoons lemon juice, ¼ teaspoon pepper, and whisk until smooth. Add 1 cup half & half and bring to a simmer. Season with salt and pepper to taste. Pour sauce over the chicken and mushrooms.

Cover with foil and bake at 350˚F for 45 minutes. Serve warm or hot over mashed potatoes, pasta or rice.

Don't use a Dutch oven for this recipe, it just doesn't turn out right. It's important that the chicken is in a single layer in the pan for baking. You can add artichoke to this, but don't try zucchini (turns to mush).
