Why You’ll Love This Recipe
This recipe is a great choice when you want chicken breasts that stay moist and flavorful. The creamy spinach filling adds richness and keeps the chicken from tasting dry, while the mozzarella gives every bite a cheesy finish. It also uses a short ingredient list, cooks in one pan, and pairs well with pasta, rice, potatoes, or a fresh salad. Since the filling is simple, it is also easy to adjust with your favorite herbs or cheese blends.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1/2 small sweet onion, grated
1 garlic clove, minced or finely grated
1 (10-ounce) box frozen spinach, thawed and squeezed dry
Grate the sweet onion using the large holes of a box grater and finely grate or mince the garlic. Add both to a medium bowl.
Add the thawed and well-squeezed spinach, cream cheese, mozzarella, and 1/2 teaspoon of the kosher salt to the bowl. Mix until the filling is fully combined.
Place one chicken breast on a cutting board. Press your hand on top and carefully cut a pocket into the thickest side, making the opening about 3 inches wide and cutting about three-quarters of the way through without slicing all the way through. Repeat with the remaining chicken breasts.
Pat the chicken dry on all sides. Season the outside and inside of each pocket with the remaining 1/2 teaspoon kosher salt.
Divide the spinach mixture evenly and stuff it into the pocket of each chicken breast.
Heat the olive oil in a large skillet over medium-high heat until shimmering.
Add the stuffed chicken breasts to the skillet and cook undisturbed for 5 to 7 minutes, until nicely browned on the first side.
Flip the chicken breasts with a spatula. Add the butter to the center of the pan and swirl gently as it melts.
Continue cooking for 5 to 7 minutes more, or until the chicken reaches an internal temperature of 165°F.
Transfer the chicken to a plate or cutting board and let it rest for 3 minutes before slicing. Finish with black pepper if desired and serve warm.

Variations
You can change this recipe in several easy ways without losing its creamy, savory appeal. Swap the mozzarella for Monterey Jack, provolone, or a mild cheddar for a different cheesy flavor. Add a spoonful of grated Parmesan to the filling for a saltier finish. A pinch of red pepper flakes can add gentle heat, while chopped parsley or Italian seasoning can bring a more herb-forward taste. You can also add finely chopped sautéed mushrooms to the filling if you want more depth and texture.
Storage/Reheating
Store leftover stuffed chicken in an airtight container in the refrigerator for up to 4 days.
To reheat, place the chicken in a covered baking dish and warm it in a 325°F oven until heated through. You can also reheat it gently in a skillet over low heat with a small splash of water to keep it from drying out. For a quick option, microwave individual portions in short intervals, turning as needed, until hot. Make sure the center is fully heated before serving.
FAQs
Can I use fresh spinach instead of frozen spinach?
Yes. Cook the fresh spinach first until wilted, then squeeze out as much moisture as possible before mixing it into the filling.
How do I keep the filling from leaking out?
Do not cut all the way through the chicken breast when making the pocket. A deep pocket with sealed sides helps keep the filling in place while cooking.
Do I need toothpicks for this recipe?
Usually no, as long as the pocket is cut carefully and not overfilled. If a breast opens too much, you can secure it with one or two toothpicks.
What is the best skillet to use?
A large heavy skillet works best. Cast iron or another sturdy skillet helps create a nice golden crust and cooks the chicken evenly.
How do I know when the chicken is done?
The safest and most accurate way is to use a meat thermometer. The thickest part of the chicken should reach 165°F.
Can I make this recipe ahead of time?
Yes. You can prepare and stuff the chicken several hours in advance, then refrigerate it until you are ready to cook.
Can I freeze spinach stuffed chicken breasts?
Yes. Cool the cooked chicken completely, wrap it well, and freeze it in an airtight container for up to 2 months. Thaw in the refrigerator before reheating.
What should I serve with this dish?
It goes well with mashed potatoes, roasted vegetables, rice, buttered noodles, or a crisp green salad.
Can I use larger chicken breasts?
Yes, but they may need a little more cooking time. Try to use similar-sized pieces so they finish cooking at the same rate.
Why is my filling watery?
That usually happens when the spinach is not squeezed dry enough. Removing as much moisture as possible before mixing is the key to a thick, creamy filling.
