Here’s how to prepare the amazing Slow Cooker Chicken Marsala Delight:

1. Prepare the Chicken: Season the chicken breasts with salt and black pepper on both sides.
2. Sauté: Heat olive oil and butter in a skillet over medium heat. Once hot, add the chicken breasts and sear for 3-4 minutes on each side until golden. Remove from heat.
3. Prepare Vegetables: In the same skillet, add diced onions and garlic. Sauté for 2-3 minutes until the onions are translucent and fragrant.
4. Layer the Slow Cooker: In your slow cooker, place the sliced mushrooms at the bottom.
5. Add Chicken: Lay the seared chicken breasts on top of the mushrooms.
6. Add Aromatics: Pour the sautéed onions and garlic over the chicken. Then, sprinkle thyme and oregano evenly.
7. Pour Liquids: Carefully pour the Marsala wine and chicken broth over the layers in the slow cooker.
8. Cook: Cover and cook on low for 4-6 hours, or on high for 2-3 hours, until the chicken is tender and easily shreds.
9. Thicken the Sauce (Optional): If you prefer a thicker sauce, remove the chicken once cooked, whisk a tablespoon of cornstarch with a little water, and slowly stir this mixture into the sauce. Cook on high for an additional 15-30 minutes until thickened.
10. Garnish: Serve your dish topped with chopped fresh parsley for added color and flavor.

With these straightforward steps, you’ll have a mouth-watering dinner ready to impress everyone at the table.
