Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 190°C. While the oven heats, prepare your spinach by wilting it in a pan over medium heat for about 2-3 minutes until it drastically reduces in volume. No oil is needed as the natural moisture will help it wilt. Once wilted, transfer to a colander and press firmly with the back of a spoon to remove excess moisture – this is crucial to prevent a watery filling.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Chop the cooled spinach and combine it in a medium bowl with the softened cream cheese, 75g of the mozzarella, all the parmesan, minced garlic, dried oregano, and red pepper flakes if using. Mix thoroughly until well combined – this creates your creamy filling that will remain moist during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Place the chicken breasts on a cutting board and, using a sharp knife, carefully cut a deep pocket horizontally into the thickest side of each chicken breast. Be careful not to cut all the way through – you want to create a pocket while keeping the chicken intact on three sides to hold the filling.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Divide the spinach and cheese mixture evenly between the chicken breasts, gently stuffing it into the pockets you've created. Don't overfill as the cheese will expand slightly during cooking. Secure the openings with toothpicks if needed to prevent the filling from leaking out during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Place the stuffed chicken breasts in a baking dish. Drizzle with olive oil and rub it over the chicken to ensure even coating. Season each breast with paprika, salt, and pepper, making sure to season all sides for maximum flavor development.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Sprinkle the remaining 25g of mozzarella cheese over the stuffed chicken breasts. This will create a delicious golden crust on top as it bakes. The cheese also helps seal in moisture, keeping the chicken juicy.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Bake in the preheated oven for 22-25 minutes, or until the chicken reaches an internal temperature of 74°C when tested with a meat thermometer. The cooking time may vary depending on the thickness of your chicken breasts, so using a thermometer ensures perfectly cooked chicken that remains juicy.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Once cooked, remove from the oven and let the chicken rest for 5 minutes before serving. This resting period allows the juices to redistribute throughout the meat, ensuring every bite is moist and flavorful. Remember to remove the toothpicks before serving!</li></ol>

Chef’s Notes

A few helpful details for making this recipe.

Can I prepare this stuffed chicken recipe ahead of time?

Yes! You can prepare the stuffed chicken up to 24 hours in advance. Assemble completely, cover tightly with cling film, and refrigerate. Add 2-3 extra minutes to the baking time when cooking from chilled. You can also freeze the unbaked stuffed breasts for up to 3 months in airtight containers.

How do I prevent the filling from leaking out during baking?

To prevent leakage, ensure you create a proper pocket rather than cutting all the way through, squeeze excess moisture from the spinach, secure openings with toothpicks, don't overfill the chicken, and allow the cheese to slightly cool before stuffing so it's not too runny when inserted into the chicken breast.

What sides pair well with low-carb stuffed chicken breasts?

Complement your stuffed chicken with keto-friendly sides like roasted cauliflower, sautéed asparagus, zucchini noodles, a simple green salad with olive oil dressing, mashed cauliflower, or sautéed mushrooms. These vegetables maintain the low-carb profile while adding variety to your meal.
