Set your oven to 200°C (180°C if using fan setting) to preheat. While it's warming up, carefully cut a pocket into each chicken breast without slicing all the way through. Rub salt and pepper inside and outside each breast, dividing half the seasoning between them.

Start by melting the butter in an oven-safe skillet over high heat. Toss in the mushrooms and cook for about 3 minutes until they start looking golden. Stir in garlic, thyme, and the rest of the salt and pepper. Let everything cook for 2 more minutes until the mushrooms are nicely browned. Throw in the spinach, stirring for about 30 seconds until it softens.

Gently fill the pockets of the chicken with the mushroom-spinach mix. Lay the cheese on top of the filling. Close the openings as much as possible with toothpicks—don’t worry if they don’t close all the way.

Quickly wipe the skillet clean with a paper towel. Heat the olive oil over medium-high and sear both sides of the stuffed chicken breasts for about 1.5 minutes each, so they get a nice golden brown color.

Move the skillet with the browned chicken into the hot oven. Let it bake for around 15 minutes or until the thickest part of the chicken reaches 65°C. Make sure to check the temp of the meat, not the filling.

Once the chicken is done, take it out of the oven and set it on a plate. Lightly cover it with foil and let it sit for about 5 minutes. Serve warm, maybe with creamy lemon-herb risotto and a spinach salad tossed with balsamic dressing if you're feeling fancy!
