- Pat each chicken breast dry with a paper towel. Season each all over with 1/2 teaspoon salt. 
- Line a rimmed baking sheet with aluminum foil, turning the ends up to keep in juices while cooking. Preheat the oven to broil and set an oven rack 6 inches from the heat. 
- Add the mushrooms to the prepared baking sheet. In a small, microwave-safe bowl, melt 4 tablespoons of the butter in the microwave. Drizzle it over the mushrooms, gently toss to coat, then spread the mushrooms in one layer. Nestle the chicken breasts, skin-side up, between the mushrooms, then broil the chicken and mushrooms 6 inches from the heat until the chicken skin is crisp and deep golden-brown but not burned, about 10 minutes. 
- Turn down the heat to 250°F. Continue cooking until the chicken is cooked through, about 25 minutes. 
- Meanwhile, heat 1 tablespoon of the remaining butter in a large skillet over medium heat, add the spinach. Cook, stirring often until the spinach starts to wilt. Season to taste with salt and pepper. Keep warm on the stovetop. 
- Halve each cooked chicken breast widthwise, then divide the breasts among 4 dinner plates. 
- Gently stir the remaining 2 tablespoons butter and the lemon juice into the mushrooms. Season to taste with salt and pepper. Spoon the mushrooms and sauce around the plated chicken, divide the spinach among the 4 plates, and serve. 
it is very tasty and easy to prepare. I am delighted!
This was delicious! I loved the broiled mushrooms! And it was fast and easy, perfect for a weekday meal. The whole family liked it and I will definitely make it again .
This is a winner according to my family! Healthy, easy and yummy! We added a little garlic to the spinach and a fresh lemon slice on the side!
We made this last week for 4 people, I think I’m going to make it again this week.
