1. Preheat your oven to 375°F (190°C). This temperature is perfect for cooking the chicken through without drying it out.
2. Using a sharp knife, carefully slice a pocket into each chicken breast. I like to go about halfway through the thickness—just enough to stuff without cutting all the way through.
3. In a small bowl, mix the chopped spinach, cranberries, minced garlic, salt, pepper, and thyme. This mixture is your flavor bomb.
4. Stuff each chicken breast pocket with the spinach-cranberry mixture, then add a couple of slices of brie on top inside the pocket. The brie melts into a creamy surprise as it cooks.
5. Secure the openings with toothpicks or kitchen twine to keep the filling inside. I remember the first time I didn’t do this and ended up with a cheesy mess in the oven—lesson learned!
6. Heat olive oil in an oven-safe skillet over medium-high heat. Once hot, sear the chicken breasts for 2-3 minutes on each side until golden brown. This step locks in juices and adds a beautiful color.
7. Transfer the skillet to the preheated oven and bake for 18-22 minutes, or until the chicken reaches an internal temperature of 165°F (74°C). If you don’t have an oven-safe skillet, transfer the chicken to a baking dish after searing.
8. Remove from oven and let the chicken rest for 5 minutes before serving. This helps the juices redistribute and keeps the chicken moist.

In my experience, resting the chicken is one of those small steps that really elevates the dish. I know we’re all in a rush sometimes, but trust me on this—it’s worth the wait.
