Ingredients Needed:
- Chicken Breasts: 4 boneless, skinless breasts (about 8 oz each).
- Spinach: 6 oz of fresh spinach (you can also use frozen, just be sure to drain it well).
- Cream Cheese: 2 oz, softened for easier mixing.
- Garlic: 2 cloves, minced.
- Mozzarella Cheese: 1 cup shredded, divided (for the filling and topping).
- Roma Tomato: 1 medium tomato, sliced thinly.
- Olive Oil: For searing.
Step-by-Step Instructions:
- Prepare the Chicken: Preheat your oven to 450°F (232°C). Pat the chicken breasts dry and season both sides with sea salt and black pepper. Using a sharp knife, cut a horizontal slit in each chicken breast to create a pocket for the stuffing.
- Make the Filling: In a bowl, steam the spinach in the microwave for 2-3 minutes, or sauté it on the stove for 3-5 minutes until wilted. Let it cool, then squeeze out excess water. In another bowl, mash the softened cream cheese and minced garlic together. Stir in ½ cup of shredded mozzarella cheese, then add the spinach mixture.
- Stuff the Chicken: Stuff each chicken breast with the spinach and cheese mixture. Use toothpicks to secure the filling inside.
- Sear the Chicken: Heat olive oil in a large cast-iron skillet over medium-high heat. Add the stuffed chicken breasts and sear each side for 4-5 minutes until golden brown.
- Add Toppings: Quickly top each chicken breast with two slices of Roma tomato and sprinkle with the remaining mozzarella cheese.
- Bake: Transfer the skillet to the oven and bake for 15 minutes, or until the internal temperature of the chicken reaches 165°F (74°C). If the cheese isn’t as browned as you’d like, broil for 1-3 minutes.
- Serve: Let the chicken rest for a few minutes before serving. Pair with roasted vegetables, rice, or a fresh salad for a complete meal.
Recipe Tips:
- Use a Meat Thermometer: To ensure your chicken is cooked through, check the internal temperature. It should reach 165°F (74°C).
- Broil for Extra Color: If you want a more golden, crispy cheese topping, broil the chicken for a few minutes at the end.
- Rest the Chicken: Let the chicken rest for a few minutes after baking to keep it juicy.
Serving Suggestions: This spinach stuffed chicken breast pairs wonderfully with:
- Vegetables: Roasted zucchini, baked cauliflower, or green beans almondine.

- Rice or Noodles: For a healthier twist, try cauliflower rice or zucchini noodles.
- Salad: Pair it with a Mediterranean, Caesar, or Greek salad for a refreshing side.
Storage & Meal Prep Tips:
- Store: Leftovers can be stored in an airtight container in the fridge for 3-5 days.
