Start by preheating your oven to 200°C/390°F (or 180°C fan-forced). While it's heating up, take each chicken breast and carefully cut a pocket into the side - be careful not to cut all the way through! Try to cut on the side with the natural fold to keep the smooth side looking pretty. Season both inside and outside of the chicken with half of the salt and pepper.

Grab a heavy-based, oven-proof skillet and melt that butter over high heat. Toss in your mushrooms and let them cook for about 3 minutes until they start turning golden. Now add the garlic, thyme, and the rest of your salt and pepper. Keep cooking for another 2 minutes until those mushrooms are beautifully golden. Throw in the baby spinach and give it a quick stir until it wilts - this should only take about 30 seconds.

Now for the fun part! Carefully stuff your mushroom mixture into the pocket of each chicken breast. Top that delicious filling with cheese slices. Grab some toothpicks to seal the openings as best you can - don't worry about making them completely sealed, mostly closed is good enough for cooking.

Give your skillet a quick wipe with paper towels. Heat the olive oil over medium-high heat, then sear each side of your stuffed chicken breasts for about 1½ minutes until they're gorgeously golden.

Transfer your skillet with those golden chicken breasts straight into the preheated oven. Let them bake for about 15 minutes, or until the chicken reaches an internal temperature of 65°C/149°F. Make sure you're checking the temperature of the chicken itself, not just the filling!

Once they're perfectly cooked, take your chicken out of the oven and transfer to a plate. Cover loosely with foil and let them rest for 5 minutes to keep all those juices inside. Serve warm with a side of creamy Baked Lemon Herb Risotto and baby spinach drizzled with Balsamic Dressing for a truly wonderful meal.
