Ingredients:
- 2 chicken breasts (approximately 220g or 7oz each, skinless and boneless)
- 3/4 teaspoon salt
- 1/4 teaspoon black pepper
- 2 tablespoons unsalted butter (30g)
- 7 oz mushrooms, sliced about 1/8″ thick (approximately 2 full cups, 200g)
- 2 cloves garlic, finely minced
- 1/2 teaspoon thyme leaves
- 2 cups fresh baby spinach
- 3 oz mozzarella cheese, sliced (or any cheese that melts well, 80g)
- 1 tablespoon olive oil
Preparation and Stuffing
Prepping the Chicken
The first step is to prepare our chicken breasts for stuffing. Take your skinless, boneless chicken breasts and place them on a clean cutting board. You’ll want to create a pocket for the delicious filling. To do this, carefully slice horizontally into the thickest part of each chicken breast, stopping about 1/2 inch from the other side. Imagin extracte you’re opening a book, but don’t cut all the way through. This pocket will allow us to stuff the chicken generously. Once you’ve made the pocket, season both sides of the chicken breasts – inside and out – with the 3/4 teaspoon of salt and 1/4 teaspoon of black pepper. This ensures the chicken itself is flavorful.
Making the Mushroom and Spinach Filling
Now for the star of the show, the filling! In a large skillet, melt the 2 tablespoons of unsalted butter over medium heat. Once the butter is melted and shimmering, add your sliced mushrooms. It might seem like a lot of mushrooms, but they will cook down significantly. Sauté the mushrooms for about 5-7 minutes, stirring occasionally, until they are nicely browned and have released most of their moisture. This browning is crucial for developing a deep, earthy flavor.
Next, add the finely minced garlic to the skillet with the mushrooms. Cook for another minute until fragrant, being careful not to burn the garlic. Burned garlic can turn bitter, so keep an eye on it. Stir in the 1/2 teaspoon of thyme leaves and cook for another 30 seconds, allowing the thyme to release its aromatic oils.
Now, it’s time to wilt the spinach. Add the 2 cups of fresh baby spinach to the skillet. It will look very full, but don’t worry. Stir the spinach into the mushroom and garlic mixture. The heat from the pan will quickly wilt the spinach down. Continue to stir until the spinach is fully wilted and incorporated into the mushroom mixture, which should only take about 1-2 minutes. Remove the skillet from the heat.
Stuffing the Chicken Breasts
With our flavorful filling ready, it’s time to stuff the chicken. Carefully open up the pocket you created in each chicken breast. Spoon a generous portion of the mushroom and spinach mixture into the pocket of each chicken breast. Don’t overstuff it to the point where it’s bursting, but aim to fill it nicely.
After adding the filling, place one or two slices of the 3 oz mozzarella cheese (or your chosen melting cheese) on top of the filling inside the pocket. The cheese will melt and help hold the filling together, adding a wonderful gooeyness. Gently press the sides of the chicken breast together to enclose the filling as much as possible. If the pocket seems a little tricky to keep closed, you can secure it with a toothpick, though often it stays closed well enough on its own.
Cooking the Stuffed Chicken
Searing the Chicken
Heat the 1 tablespoon of olive oil in the same skillet you used for the filling over medium-high heat. Once the oil is hot and shimmering, carefully place the stuffed chicken breasts into the skillet. Sear the chicken for about 3-4 minutes on each side, until it has a beautiful golden-brown color. This searing step is important for developing a lovely crust and locking in the juices.
Baking to Perfection
Preheat your oven to 375°F (190°C). Once the chicken breasts are nicely seared, transfer them from the skillet to a baking dish or a small oven-safe skillet. Place the baking dish in the preheated oven. Bake for 20-25 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F (74°C) when tested with a meat thermometer. The exact baking time will depend on the thickness of your chicken breasts. You want the chicken to be fully cooked and the cheese inside to be melted and bubbly.
Resting for Juiciness
Once the chicken is cooked, remove it from the oven and let it rest for about 5 minutes before serving. This resting period is crucial for allowing the juices to redistribute throughout the chicken, ensuring a tender and moist final product. If you cut into it too soon, all those delicious juices will run out onto the plate.
