This super simple, rich pressure cooker chicken and mushrooms recipe cooks in minutes. There's something about the combination of mushrooms and chicken that is so delicious. Tender mushrooms have a meaty flavor known as "Umami" In japanese cooking. This is actually the fifth flavor that your taste buds sense, in addition to sour, sweet, bitter, and salty. You can use chicken thighs in place of the chicken breasts in this easy recipe. Just make sure that you use a full two pounds of the thighs. You can buy boneless, skinless chicken breasts or thighs, or buy bone-in, skin-on products and remove the skin and bone yourself. You can save the bones in the freezer to make stock. You can season this recipe any way you'd like. Use a spice other than thyme. Add more garlic, or omit it. Use a different variety of mushrooms, or add some sliced bell pepper strips, some green beans, or even thinly sliced carrots. One of the nicest things about cooking main dishes is that you can substitute to your heart's content and the finished dish will still be wonderful. Serve this one-dish meal with a green salad or a fruit salad, along with some dinner rolls or croissants. A nice glass of wine is all you need for a fabulous dinner.
