Ingredients
- Boneless skinless chicken breasts: choose larger breasts that are easier to stuff without tearing
- Roasted red peppers: they add a sweet smoky flavor that elevates the entire dish
- Fresh spinach: provides color contrast texture and nutrition without overpowering other flavors
- Mozzarella cheese: the melty texture creates a creamy binding for the filling
- Olive oil: helps create a golden exterior and carries the seasoning flavors
- Garlic powder: infuses flavor throughout without the risk of burning that fresh garlic has
- Italian seasoning: this blend adds complexity without needing multiple spice jars
- Salt and pepper: enhances all other flavors and balances the dish
Step-by-Step Instructions
- Prepare the chicken:
- Using a sharp knife make a horizontal cut along the thickest side of each chicken breast creating a pocket about 3/4 of the way through. Be careful not to cut completely through as the pocket needs to hold the filling. Pat the chicken dry with paper towels which helps seasonings stick better and promotes browning.
- Create the filling mixture:
- Chop the roasted red peppers into small pieces ensuring even distribution throughout the filling. Roughly chop the spinach if the leaves are large making it easier to stuff into the pocket. Combine the peppers spinach and mozzarella in a bowl gently tossing to create an evenly mixed filling that will melt beautifully.
- Stuff and secure:
- Open the chicken pocket with one hand while using your other hand to stuff approximately 1/4 of the filling mixture into each breast. Press gently to distribute the filling evenly throughout the pocket. If the opening seems large secure with toothpicks inserted horizontally to keep the filling from spilling out during baking.
- Season and prepare for baking:
- Whisk together olive oil garlic powder Italian seasoning salt and pepper in a small bowl until well combined. Use a pastry brush to coat both sides of each stuffed chicken breast ensuring even coverage of the seasoning mixture. This creates a flavorful crust while helping the chicken brown beautifully.
- Bake to perfection:
- Arrange the stuffed chicken breasts in a baking dish leaving space between each piece to allow for even cooking. Bake uncovered at 375°F for 25 to 30 minutes until the chicken reaches an internal temperature of 165°F and the cheese has melted. Allow the chicken to rest for 5 minutes before serving which helps the juices redistribute throughout the meat.

The roasted red peppers are truly the star ingredient in this recipe. I once made this dish with peppers I roasted myself over an open flame and the smoky flavor was absolutely incredible. My husband who typically finds chicken breast boring couldn't stop raving about how juicy and flavorful it was. That moment convinced me that taking a few extra minutes to choose quality ingredients really makes all the difference.
Make Ahead Options
You can prepare these stuffed chicken breasts up to 24 hours before cooking. Simply assemble follow all steps except baking then cover tightly with plastic wrap and refrigerate. When ready to cook remove from the refrigerator 30 minutes before baking to take the chill off which helps ensure even cooking. You may need to add a few extra minutes to the baking time if cooking from cold. This make ahead option is perfect for entertaining when you want to enjoy time with your guests instead of being stuck in the kitchen.

Simple Substitutions
This recipe is incredibly versatile and can be adapted based on what you have available. Instead of mozzarella try using provolone goat cheese or even a mixture of cheeses for different flavor profiles. Sun dried tomatoes make an excellent alternative to roasted red peppers adding a more intense tangy flavor. Kale or arugula can replace spinach bringing different nutritional benefits and slightly different tastes. For added richness consider wrapping each stuffed chicken breast with prosciutto or bacon before baking which also helps seal in the filling.
Serving Suggestions
This stuffed chicken pairs beautifully with a variety of sides. For a complete meal serve alongside roasted garlic mashed potatoes and steamed asparagus. A light arugula salad dressed with lemon and olive oil makes a refreshing accompaniment that balances the richness of the chicken. For a more elegant presentation slice the chicken on a bias to show off the colorful filling and arrange over a bed of risotto or polenta. A drizzle of balsamic glaze over the top adds a professional looking finish and complements the flavors perfectly.
Essential Kitchen Tools
Using the right tools makes preparing this recipe much easier. A sharp chef's knife is crucial for creating the pocket in the chicken without tearing the meat. Heavy duty toothpicks work better than standard ones for securing the filling. A meat thermometer takes the guesswork out of knowing when the chicken is perfectly cooked without cutting into it and losing precious juices. A good quality baking dish that conducts heat evenly ensures that all pieces of chicken cook at the same rate.
