Ingredients

For the chicken:

• 4 boneless, skinless chicken breasts (about 6-8 oz each)
• 2 tablespoons olive oil
• 1 teaspoon garlic powder
• 1 teaspoon paprika
• ½ teaspoon Italian seasoning
• Salt and fresh ground black pepper to taste

For the filling:

• 6 oz fresh spinach (about 4 cups), roughly chopped
• 8 oz cream cheese, softened
• ½ cup shredded mozzarella cheese
• ¼ cup grated Parmesan cheese
• 2 cloves garlic, minced
• ¼ teaspoon red pepper flakes (optional)
• 1 tablespoon fresh lemon juice
• 1 teaspoon lemon zest

Choose high-quality chicken breasts that are similar in size for even cooking. Fresh spinach provides the best flavor and texture, though thawed frozen spinach (well-drained) can work in a pinch. The combination of three cheeses creates depth of flavor, but feel free to adjust based on what you have available.

Pro Tips

Perfect Butterfly Technique: The key to successful Spinach Stuffed Chicken Breasts is proper butterflying. Place your hand flat on top of the chicken breast and use a sharp knife to slice horizontally through the middle, stopping just before cutting all the way through. This creates a pocket for the filling while keeping the chicken intact. For even cooking, use a meat mallet to gently pound the chicken to an even thickness of about ½-inch.

Prevent Filling Leakage: After stuffing your chicken, secure it with toothpicks placed parallel to the cutting board. This keeps the filling from escaping during cooking. For extra security, you can dredge the stuffed chicken in flour before searing – this creates a barrier that helps seal in the filling and promotes better browning.

Temperature is Everything: Use an instant-read thermometer to ensure perfect doneness. The chicken should reach 165°F (74°C) at the thickest part without touching the filling. Let the chicken rest for 5 minutes after cooking – this allows the juices to redistribute, resulting in moister chicken and giving the filling time to set slightly.

Instructions

Step 1: Prepare the Filling
In a medium bowl, combine the chopped spinach, softened cream cheese, mozzarella, Parmesan, minced garlic, red pepper flakes (if using), lemon juice, and zest. Mix thoroughly until all ingredients are well incorporated. Season with a pinch of salt and pepper. Set aside while you prepare the chicken.

Step 2: Prepare the Chicken
Preheat your oven to 375°F (190°C). Butterfly each chicken breast by placing your hand flat on top and carefully slicing horizontally through the middle, stopping just before cutting all the way through. Open each breast like a book. For even cooking, gently pound the chicken to about ½-inch thickness using a meat mallet or heavy pan.

Step 3: Season and Stuff
Season both sides of each chicken breast with salt, pepper, garlic powder, paprika, and Italian seasoning. Place about ¼ of the spinach filling onto one half of each butterflied chicken breast, leaving about a ½-inch border around the edges. Fold the empty half over the filling and secure with toothpicks placed parallel to the cutting board.

Step 4: Sear the Chicken
Heat olive oil in a large oven-safe skillet over medium-high heat. When the oil is hot, carefully add the stuffed chicken breasts and sear for 3-4 minutes per side until golden brown. Work in batches if needed to avoid overcrowding the pan, which would prevent proper browning.

Step 5: Finish in the Oven
Transfer the skillet to the preheated oven (or move chicken to a baking dish if your skillet isn’t oven-safe). Bake for 15-20 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) when tested with a meat thermometer in the thickest part.

Step 6: Rest and Serve
Remove the chicken from the oven and let it rest for 5 minutes before carefully removing the toothpicks. This resting period allows the juices to redistribute throughout the chicken and gives the filling time to set slightly. Slice each breast on a diagonal to showcase the beautiful filling and serve immediately.

Variations

Mediterranean Style: Transform your Spinach Stuffed Chicken Breasts with Mediterranean flavors by adding ¼ cup of chopped sun-dried tomatoes and ¼ cup of crumbled feta cheese to the spinach mixture. Replace the Italian seasoning with 1 teaspoon of dried oregano and add 2 tablespoons of chopped kalamata olives. This variation pairs beautifully with a side of lemon-herb couscous.

Low-Carb Keto Version: Make this dish keto-friendly by omitting the flour dredge. Increase the Parmesan cheese to ½ cup in the filling and add 2 tablespoons of almond flour for texture. You can also mix 1 tablespoon of ground pork rinds with your spices to coat the outside of the chicken for extra crispiness without the carbs.

Spicy Southwestern: Add a kick to your chicken by incorporating ¼ cup of chopped roasted red peppers, 1 diced jalapeño (seeds removed for less heat), and substituting pepper jack for the mozzarella cheese. Season the chicken with 1 teaspoon of cumin and ½ teaspoon of chili powder instead of Italian seasoning for a southwestern flair.

Storage and Serving

Spinach Stuffed Chicken Breasts can be refrigerated in an airtight container for up to 3 days. For best results when reheating, place the chicken in a 350°F (175°C) oven for about 15 minutes or until heated through. Avoid microwaving if possible, as it can make the chicken rubbery and cause the filling to separate.

For freezing, wrap each cooled stuffed chicken breast individually in plastic wrap, then aluminum foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating as directed above.

Serve these flavorful chicken breasts with roasted garlic mashed potatoes and steamed asparagus for a complete meal. For a lighter option, pair with a fresh arugula salad dressed with lemon vinaigrette. These stuffed chicken breasts also complement creamy risotto beautifully, allowing the rice to soak up any escaped filling for an extra flavor boost.

FAQs

Can I prepare Spinach Stuffed Chicken Breasts ahead of time?
Yes! You can stuff the chicken breasts up to 24 hours in advance. Keep them covered in the refrigerator and bring to room temperature for about 15 minutes before cooking.

How do I know when the chicken is fully cooked?
The most reliable method is using an instant-read thermometer, which should register 165°F (74°C) at the thickest part of the chicken (not in the filling). If you don’t have a thermometer, cut into the thickest part – the meat should be white with no pink remaining.

Can I use frozen spinach instead of fresh?
Yes, but thaw it completely and squeeze out all excess moisture before using. About 6 oz (170g) of frozen spinach, thawed and drained, can replace the fresh spinach in this recipe.

My filling keeps leaking out during cooking. What am I doing wrong?
Try securing the chicken with more toothpicks, making sure they’re placed parallel to the cutting surface. You can also try chilling the stuffed chicken for 15-30 minutes before cooking to help the filling firm up.

What’s the best cheese substitute if I don’t have cream cheese?
Ricotta cheese makes a good substitute, though the filling will be slightly less creamy. Mascarpone is another excellent alternative that maintains the creamy texture.
