Cheesy Spinach Stuffed Chicken (Printable)

Chicken breasts stuffed with creamy spinach, mozzarella and sun-dried tomatoes; seared then oven-baked to golden.

# What You Need:

→ Chicken

01 - 4 large boneless, skinless chicken breasts
02 - 1 tablespoon olive oil
03 - 1 teaspoon salt
04 - ½ teaspoon black pepper
05 - 1 teaspoon garlic powder

→ Filling

06 - 4 oz cream cheese, softened
07 - 1 cup shredded mozzarella cheese
08 - 2 oz fresh spinach, roughly chopped
09 - ⅓ cup sun-dried tomatoes in oil, drained and chopped
10 - 2 cloves garlic, minced
11 - ¼ teaspoon crushed red pepper flakes (optional)
12 - 2 tablespoons grated Parmesan cheese

→ To Finish

13 - 1 tablespoon olive oil (for searing)
14 - Fresh basil or parsley, chopped (for garnish, optional)

# How to Make It:

01 - Preheat oven to 375°F.
02 - Using a sharp knife, slice a pocket into the side of each chicken breast, being careful not to cut all the way through.
03 - Season both sides of the chicken breasts evenly with salt, black pepper, and garlic powder.
04 - In a mixing bowl, combine softened cream cheese, shredded mozzarella, chopped spinach, drained and chopped sun-dried tomatoes, minced garlic, crushed red pepper flakes, and grated Parmesan. Mix thoroughly until well blended.
05 - Fill each chicken breast pocket generously with the spinach-cheese mixture. Secure the openings with toothpicks if needed to keep the filling contained.
06 - Heat 1 tablespoon olive oil in a large oven-safe skillet over medium-high heat. Sear the stuffed chicken breasts for 2 to 3 minutes per side until a golden-brown crust forms.
07 - Transfer the skillet directly to the preheated oven (or move the chicken to a baking dish). Bake for 22 to 25 minutes until the internal temperature reaches 165°F.
08 - Remove from oven, discard toothpicks, and let rest briefly. Garnish with fresh chopped basil or parsley if desired and serve hot.

# Expert Suggestions:

01 -
  • That moment when you cut into the chicken and the cheesy spinach filling oozes out is genuinely restaurant worthy without requiring professional skills.
  • Sun-dried tomatoes bring a concentrated punch of umami that makes this taste like you spent three hours cooking when it barely takes one.
02 -
  • Overstuffing the pockets is tempting but the filling will burst out and burn on the pan, so use about two heaping tablespoons per breast and press firmly.
  • An instant-read thermometer is the single tool that prevents dry chicken because visual guessing is unreliable with stuffed breasts.
03 -
  • The filling can be made a day ahead and refrigerated, which actually firms it up and makes stuffing the chicken significantly easier and less messy.
  • Letting the chicken rest after baking is not optional because those three minutes are the difference between a juicy masterpiece and a puddle of lost flavor on your cutting board.
