How To Make Roasted Red Pepper Spinach and Mozzarella Stuffed Chicken
- Prepare the Seasoning
- Combine olive oil with all the dried spices in a small bowl until they form a paste. This seasoning mixture will create a flavorful crust on the outside of the chicken that complements the filling perfectly. Make sure to mix thoroughly so the spices distribute evenly.
- Butterfly the Chicken
- Using a sharp knife, cut horizontally through the thickest part of each breast, stopping about half an inch before cutting all the way through. Open each breast like a book, creating a pocket for the filling. For even cooking, gently pound any thicker parts to create uniform thickness throughout.
- Season the Chicken
- Rub the oil and spice mixture generously over both the inside and outside of each chicken breast. Be sure to get into all the crevices for maximum flavor penetration. The oil helps the seasonings stick and promotes browning.
- Prepare the Filling
- Mix chopped spinach, diced roasted red peppers, both cheeses, and minced garlic in a medium bowl until thoroughly combined. The filling should be cohesive but still have visible pieces of each component. This creates texture and ensures every bite has a balance of flavors.
- Stuff and Fold
- Spoon a generous amount of the filling mixture onto one side of each opened chicken breast. Carefully fold the other side over to enclose the filling completely. If needed, secure with toothpicks to prevent the filling from leaking during cooking.
- Bake to Perfection
- Place the stuffed chicken breasts in a baking dish with a little space between each piece. Bake until the chicken is cooked through and the cheese is melted and bubbly inside. For an extra golden top, broil for the final few minutes while watching carefully to prevent burning.
The roasted red peppers are truly the secret weapon in this recipe. I discovered this when trying to recreate a dish I had at a small Italian restaurant in Boston. The sweet smokiness of the peppers transforms what could be an ordinary chicken dish into something memorable that even my picky nephew requests whenever he visits.
Make-Ahead Options
This stuffed chicken is perfect for meal prep or entertaining because you can prepare everything up to the baking step a day in advance. Simply stuff the chicken, place it in your baking dish, cover tightly with plastic wrap, and refrigerate. When ready to cook, remove from the refrigerator 30 minutes before baking to take the chill off, then bake as directed, adding about 5 extra minutes to the cooking time.
Perfect Pairings
Turn this impressive main dish into a complete meal by serving it alongside simple sides that complement without competing. A light arugula salad dressed with lemon and olive oil adds a peppery freshness that cuts through the richness of the cheese. For a heartier option, roasted garlic mashed potatoes or a simple risotto makes this chicken feel like a special occasion meal. If you want to keep things light and low carb, try roasted asparagus or zucchini noodles tossed with a touch of the same Mediterranean seasonings.

Troubleshooting Tips
If your chicken tends to dry out when baking, there are several easy solutions. First, be absolutely certain not to overcook it. An instant-read thermometer is invaluable here. Pull the chicken from the oven when it reaches exactly 165°F at the thickest part. Second, consider brining your chicken breasts for 30 minutes before starting the recipe. A simple solution of 4 cups water and 1/4 cup salt will help the meat retain moisture during cooking. Finally, make sure your oven is properly calibrated. Many home ovens run hot, which can lead to overcooking.

Recipe FAQs
- → Can I prepare this stuffed chicken in advance?
Yes, you can prepare the stuffed chicken breasts up to 24 hours in advance. Assemble them completely, cover tightly with plastic wrap, and refrigerate. When ready to cook, simply add about 5 minutes to the baking time since you're starting with cold chicken.
- → What sides pair well with this stuffed chicken dish?
This Mediterranean-style stuffed chicken pairs beautifully with roasted potatoes, a simple risotto, or a light garden salad. For a complete meal, consider adding steamed asparagus or roasted vegetables like zucchini and bell peppers.
- → Can I use different cheese instead of mozzarella?
Absolutely! While mozzarella provides that classic melty texture, you can substitute with provolone, fontina, or even a mild gouda. For a stronger flavor profile, consider adding small amounts of feta or goat cheese to the filling mixture.
- → How do I know when the stuffed chicken is fully cooked?
The most reliable method is using a meat thermometer - the internal temperature should reach 165°F (74°C). Without a thermometer, ensure the juices run clear when the thickest part is pierced, and the chicken is no longer pink in the center.
- → Can I use jarred roasted red peppers?
Yes! Store-bought jarred roasted red peppers work perfectly in this recipe. Just be sure to drain them well and pat them dry with paper towels before chopping to prevent excess moisture in the filling.
- → Can I freeze these stuffed chicken breasts?
You can freeze them either before or after cooking. For uncooked chicken, freeze individually on a baking sheet before transferring to freezer bags. For cooked chicken, cool completely, wrap individually, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
