Ingredients

Units Scale

For the Chicken:

  • 4 boneless, skinless chicken breasts
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1 tbsp olive oil

For the Creamy Spinach Topping:

  • 4 oz (115g) cream cheese, softened
  • 1/2 cup sour cream (or Greek yogurt)
  • 2 cloves garlic, minced
  • 1 tsp Italian seasoning
  • 1/4 tsp red pepper flakes (optional)
  • 2 cups fresh spinach, chopped
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese

Instructions

Step 1: Preheat the Oven

  1. Preheat your oven to 375°F (190°C).
  2. Lightly grease a 9×13-inch baking dish with olive oil or cooking spray.

Step 2: Prepare the Chicken

  1. Season the chicken breasts with salt, pepper, garlic powder, and onion powder.
  2. Heat 1 tbsp olive oil in a skillet over medium-high heat. Sear the chicken for 2-3 minutes per side until golden brown. Transfer to the baking dish.

Step 3: Make the Creamy Spinach Mixture

  1. In a bowl, mix cream cheese, sour cream, garlic, Italian seasoning, and red pepper flakes until smooth.
  2. Stir in the chopped spinach, ½ cup mozzarella, and Parmesan cheese.

Step 4: Assemble & Bake

  1. Spread the cream cheese spinach mixture evenly over the chicken.
  2. Sprinkle the remaining ½ cup of mozzarella on top.
  3. Bake uncovered for 25-30 minutes, until the chicken is cooked through (internal temp of 165°F/75°C) and the cheese is bubbly and golden.

Step 5: Serve & Enjoy

  1. Let rest for 5 minutes, then serve warm with steamed vegetables, cauliflower rice, or a side salad.

Notes

  • Make It Extra Cheesy: Add ½ cup shredded cheddar for more depth of flavor.
  • Dairy-Free Option: Use dairy-free cream cheese and vegan mozzarella.
  • Add Protein: Stir in cooked bacon or crumbled sausage to the spinach mixture.
  • Storage: Store in the fridge for up to 3 days. Reheat in the oven at 350°F (175°C) for 10 minutes.
