Creating Chicken Spinach and Mushroom Low Carb Oven Dish can be a fun process. Follow these easy steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C). Prepare a baking dish by lightly greasing it with olive oil.
2. Sauté Mushrooms: In a skillet over medium heat, add 1 tablespoon of olive oil. Once hot, add the sliced mushrooms and cook for about 5-7 minutes, or until they become tender and any liquid has evaporated. Remove from heat and set aside.
3. Prepare Chicken: In a large mixing bowl, combine the cubed chicken breasts with garlic powder, onion powder, salt, and pepper. Mix well to coat evenly.
4. Combine Ingredients: Add the sautéed mushrooms and chopped spinach to the bowl with the chicken. Stir to combine.
5. Cream Cheese Mixture: In another bowl, mix the softened cream cheese and grated Parmesan cheese until smooth. Fold this mixture into the chicken, mushrooms, and spinach mixture until well combined.
6. Transfer to Baking Dish: Pour the entire mixture into the prepared baking dish, spreading evenly.
7. Top with Mozzarella: Sprinkle shredded mozzarella cheese on top of the mixture.
8. Bake: Place the dish in the preheated oven and bake for 35-40 minutes or until the chicken is cooked through and the cheese is golden and bubbly.
9. Garnish: Once cooked, remove from oven and let it cool slightly before serving. Garnish with fresh parsley if desired.
