Ingredients

• 4 pieces Chicken breasts, boneless and skinless
• 2 cups Portabella mushrooms, sliced
• 1 large Yellow onion, diced
• 3 cloves Garlic, minced
• 1 cup Chicken broth
• 0.5 cup Heavy cream
• 4 ounces Cream cheese, softened
• 2 tablespoons Olive oil
• 1 teaspoon Italian seasoning
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 2 tablespoons Fresh parsley, chopped (optional, for garnish)

Directions

Step 1

Heat olive oil in a large skillet over medium heat. Season the chicken breasts on both sides with salt and black pepper, then sear them in the skillet for 2-3 minutes on each side until golden brown. Remove chicken and set aside.

Step 2

In the same skillet, add the diced onion and sauté for 3-4 minutes until softened. Add the minced garlic and sliced portabella mushrooms, and cook for another 5 minutes until the mushrooms are tender.

Step 3

Stir in the chicken broth, heavy cream, cream cheese, and Italian seasoning. Cook the mixture until the cream cheese has melted and the sauce is smooth, about 2-3 minutes. Adjust seasoning with additional salt and pepper if needed.

Step 4

For Slow Cooker: Transfer the seared chicken breasts to the slow cooker. Pour the mushroom sauce over the chicken. Cover and cook on LOW for 4-5 hours or on HIGH for 2-3 hours, until the chicken is cooked through and tender.

Step 5

For Oven: Preheat your oven to 375°F (190°C). Place the seared chicken breasts in a baking dish. Pour the mushroom sauce over the chicken. Cover the dish with aluminum foil and bake for 25-30 minutes, or until the chicken's internal temperature reaches 165°F (74°C).

Step 6

Serve hot, garnished with freshly chopped parsley if desired. This dish pairs beautifully with mashed potatoes, rice, or pasta, along with a green vegetable.
