Spinach, Goat Cheese, and Pesto Stuffed Chicken Breast with Lemon Mustard Sauce

The first time I made stuffed chicken, I was barely tall enough to reach the counter comfortably. My grandmother, a formidable woman in the kitchen, was teaching me how to carefully create a pocket in the chicken breast, coaxing the tender meat apart without tearing it. The aroma of garlic, herbs, and melting cheese filled the air, a comforting prelude to a meal that felt both elegant and deeply satisfying. It was a lesson not just in cooking, but in patience, precision, and the joy of transforming simple ingredients into something special. While my grandmother’s recipe was her closely guarded secret, this recipe reminds me of those warm kitchen moments, and I’m excited to share this with you.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 45-50 minutes
• Total Time: 1 hour 5 minutes – 1 hour 10 minutes
• Servings: 4
• Dietary Type: Gluten-Free (if using gluten-free pesto)

Ingredients

• 4 large chicken breasts
• 200 g baby spinach
• 300 g soft fresh goat cheese, all rind removed
• 8 teaspoons basil pesto (approximately 2 teaspoons per breast, or enough to cover breast completely)
• 4 sun-dried tomatoes in oil, drained
• 8 slices prosciutto

Lemon Mustard Sauce

• 1 cup milk
• 1 teaspoon chicken stock powder
• 1 1/2 teaspoons cornflour
• 3 teaspoons Dijon mustard
• 2 tablespoons lemon juice
• 2 tablespoons dry white wine
• 1 tablespoon parsley, finely chopped
• 2 tablespoons cream
• 1 pinch cayenne pepper
• Pepper, to taste

Equipment Needed

• Meat mallet
• Large bowl
• Saucepan
• Baking dish
• Small bowl or cup for cornflour slurry

Instructions

1. Begin by preparing the chicken breasts. Place each breast between two sheets of plastic wrap or in a ziplock bag. Use a meat mallet to pound each breast until it is approximately 1/4 inch thick and of even thickness throughout. This step is crucial for even cooking.

2. Next, prepare the spinach and goat cheese filling. Boil the baby spinach until tender. Drain it thoroughly and squeeze out all excess water. The drier the spinach, the better the filling’s consistency will be. In a large bowl, combine the cooked spinach with the soft goat cheese until well mixed. Ensure the goat cheese is evenly distributed throughout the spinach.

3. Now, assemble the stuffed chicken breasts. Spread 2 teaspoons of basil pesto over the inside of each flattened chicken breast, ensuring the entire surface is covered. This pesto layer adds a burst of flavor and helps to keep the chicken moist.

4. Spoon the spinach and goat cheese mixture down the center of each chicken breast lengthwise. Distribute the filling evenly to prevent bulging during cooking.

5. Cut each sun-dried tomato into 4 slices. Place the tomato slices on top of the spinach mixture, running the length of the breast. Use 1 tomato per breast, arranging the slices evenly.

6. Fold the chicken breast over to cover the filling completely. Wrap 2 slices of prosciutto around each breast to secure the filling. The prosciutto not only helps to hold everything together but also adds a salty, savory layer to the dish.

7. Lightly oil the bottom of a baking dish. Place the stuffed chicken breasts inside. Make sure the breasts are not overcrowded in the dish.

8. Bake the breasts in a preheated oven at 180°C (350°F) for 45-50 minutes, or until the chicken is cooked through. Cooking times will vary depending on the thickness of the breasts, so it’s important to check for doneness. The internal temperature should reach 74°C (165°F). If the prosciutto begins to brown too quickly, tent the dish loosely with foil.

9. While the chicken is baking, prepare the Lemon Mustard Sauce. In a saucepan, heat the milk and chicken stock powder. In a small bowl or cup, mix the cornflour with a little water to form a slurry. Add the cornflour slurry to the milk mixture and stir continuously until the mixture thickens slightly.

10. Add the Dijon mustard, lemon juice, and dry white wine to the sauce. Stir to combine all ingredients thoroughly.

11. Add the cream, cayenne pepper, parsley, and pepper to taste. Heat the sauce over medium heat until it has thickened to your desired consistency. Taste and adjust seasonings as needed.

12. Note: You can leave the sauce over low heat, stirring occasionally, while the chicken finishes cooking. This allows the flavors to meld together beautifully.

13. To serve: Slice the chicken breast in half, plate it artfully, and drizzle generously with the Lemon Mustard Sauce.

Expert Tips & Tricks

• Pounding the chicken is essential for even cooking. Make sure to pound each breast to a uniform thickness to prevent some parts from drying out while others are still undercooked.
• Don’t overfill the chicken breasts. Too much filling can cause them to burst open during baking.
• If you don’t have prosciutto, you can use thinly sliced bacon or pancetta as a substitute.
• For a richer sauce, use chicken stock instead of chicken stock powder mixed with water.
• To prevent the goat cheese from melting too much during cooking, chill the stuffed chicken breasts in the refrigerator for about 15-20 minutes before baking.

Serving & Storage Suggestions

To serve, slice the stuffed chicken breast in half on a slight diagonal to showcase the colorful filling. Arrange the slices on a plate and generously drizzle with the Lemon Mustard Sauce. Garnish with fresh parsley or a lemon wedge for added visual appeal. This dish pairs beautifully with roasted asparagus, mashed potatoes, or a simple green salad.

Leftover stuffed chicken breast can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 175°C (350°F) until heated through, or microwave in short intervals, being careful not to overcook. You can also freeze the cooked chicken breasts for up to 2 months. Thaw completely in the refrigerator before reheating. The sauce should be stored separately and can also be reheated gently on the stovetop or in the microwave.
