Making the Stuffed Chicken
(scroll to the bottom of the post for the full recipe!)
Preparing the Chicken Breasts
Pat 4 medium chicken breasts completely dry then carefully cut a horizontal slit in each. (about 2/3 of the way through)
Season the chicken with s&p to taste then dredge in flour, shaking off excess.
Now we’re ready to pan sear the chicken breasts in oil/butter until a deep golden brown on each side.
Why are we searing before filling the chicken? This prevents the filling from falling out when you’re searing it! A nifty little trick a sweet reader shared with me. ♥
Roasted Red Pepper Spinach Mozzarella Filling
Saute sliced roasted red peppers and fresh baby spinach in a little olive oil until the spinach is just wilted.
Toss a little fresh minced garlic into the pan and let that cook 1 minute until fragrant. Season ‘er up with more s&p to taste!
Let the filling cool off slightly. While you’re waiting, slice a few thick slices of fresh mozzarella (I recommend a low-moisture fresh mozzarella)
Stuffing and Baking the Chicken
Stuff each seared chicken breast with the pepper/spinach filling and a slice of mozzarella. If you’re worried about the filling falling out while it bakes, feel free to secure with toothpicks!
Bake the chicken 20-25 minutes until each breast temps 165F. Serve alongside your desired side dish!

This entire dinner is like the perfect stuffed chicken package. They are SO good!
