Juicy chicken breasts transform into something truly special with a creamy mozzarella, sweet roasted peppers, and fresh spinach filling. This recipe has become my secret weapon for impressing guests with almost no stress and makes regular weeknights feel a little more gourmet.
I first threw this together on a busy Thursday hoping to use what was left in my fridge. My family raved and now they beg for it again and again.
Ingredients
- Boneless skinless chicken breasts: These are the classic base for stuffing Make sure to pick breasts that are similar in size so they cook evenly
- Fresh spinach leaves: Brings color and gentle flavor Choose crisp deep green leaves that are free from wilting
- Roasted red peppers: These add sweetness and tang You can use jarred or roast your own at home for extra flavor
- Mozzarella cheese: Melts perfectly for that classic pull Go for a low moisture mozzarella to avoid watery stuffing
- Garlic powder: Lends depth and aroma Use a fresh bottle for bold flavor
- Italian seasoning: Delivers classic herb notes Look for blends with oregano basil thyme for balance
- Salt and pepper: Enhances every layer of flavor Use sea salt or kosher salt if possible for clean taste
- Olive oil or melted coconut oil: For searing Helps chicken brown beautifully and keeps it moist
- Toothpicks or kitchen twine: Keeping that filling right where you want it Make sure to remove before serving
Step-by-Step Instructions
- Prep the Chicken:
- Using a sharp knife cut a deep pocket in the side of each chicken breast being careful not to slice all the way through This pocket creates a little envelope for the filling to stay inside and keeps the chicken juicy during baking
- Season the Chicken:
- Lay the breasts open and sprinkle the inside and outside with salt freshly ground pepper garlic powder and Italian seasoning Press the seasoning in gently to help it stick
- Stuff the Chicken:
- Layer a handful of fresh spinach a few generous strips of roasted red pepper and enough mozzarella cheese to fill but not overflow Tuck the edges of the chicken over and secure with toothpicks or tie with kitchen twine snugly
- Sear for Flavor:
- Heat olive oil in a heavy skillet over medium high Lay the stuffed chicken in and sear each side for about three minutes until you see rich brown color forming on both sides This builds deep flavor and seals in juices
- Bake Until Juicy:
- Carefully transfer the seared chicken to a baking dish Place in a preheated 375 degree oven and bake for twenty to twenty five minutes until the thickest part reaches 165 degrees and the cheese is bubbling Let rest for five minutes so every bite stays moist and tender

Every time I use roasted red peppers I am reminded of the first summer I spent roasting peppers on the grill with my grandfather. Their smoky sweet flavor brings back those happy days every time I make this dish for my loved ones.
Storage Tips
Keep any leftovers in an airtight container in the fridge for up to three days. For best texture, slice before reheating and cover with a damp paper towel to keep the chicken juicy.
Ingredient Substitutions
If you do not have mozzarella try provolone or even creamy goat cheese for a different twist. You can use arugula or baby kale instead of spinach for a new flavor dimension. Jarred sun dried tomatoes work instead of red peppers in a pinch.
Serving Suggestions
Serve alongside garlic butter green beans or a crisp mixed salad for a balanced meal. I love spooning the pan juices over the chicken for added richness. A side of roasted potatoes or polenta makes it extra comforting.
Cultural History
Stuffing meat with greens cheese and veggies is a classic Italian technique known as involtini. This recipe celebrates those roots with modern shortcuts like jarred peppers and ready cheese so you get that homemade feel even on a weeknight.
