Ingredients
• 3 tablespoons (45 ml / 1.5 fl oz) coconut oil, avocado oil, or ghee
• 7 ounces / 200 g (7.1 oz) cremini mushrooms, chopped
• 4 cloves garlic, minced
• 3 teaspoons (15 ml / 0.5 fl oz) dried parsley, divided
• ¾ teaspoon finely ground sea salt, divided
• ¼ teaspoon ground black pepper
• 1 pound / 455 g (16 oz) boneless, skin-on chicken breasts
• 1 teaspoon onion powder
• 1 teaspoon garlic powder
• ½ cup / 120 ml (4.1 fl oz) full-fat milk (nondairy or regular)
• 4 cups / 280 g (9.9 oz) fresh spinach, for serving
Instructions
1. Preheat your oven to 400°F / 205°C. Line a rimmed baking sheet with parchment paper for easy cleanup.
2. In a large skillet, heat the oil over medium heat. Add the chopped mushrooms, minced garlic, 2 teaspoons (10 ml / 0.3 fl oz) of parsley, ¼ teaspoon of salt, and the black pepper. Sauté for about 10 minutes, until the mushrooms are tender and have released their liquid.
3. While the mushrooms cook, prepare the chicken. Place your palm flat on top of a chicken breast and carefully slice it horizontally, stopping about ½ inch from the other side so it opens like a book.
4. Arrange the butterflied chicken breasts on your prepared baking sheet. Spoon one-quarter of the mushroom mixture into the center of each breast. If you have any extra filling, just scatter it on the pan around the chicken.
5. Fold the chicken breasts closed over the filling. In a small bowl, mix the garlic powder, onion powder, the remaining 1 teaspoon (5 ml / 0.2 fl oz) of parsley, and the remaining ½ teaspoon of salt. Sprinkle this seasoning mix evenly over the top of the chicken.
6. Carefully pour the milk into the baking sheet, around the chicken breasts. This will create your creamy pan sauce.
7. Bake for 30 to 35 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F / 74°C on a meat thermometer.
8. To serve, place a bed of fresh spinach on each of four plates. Top with a stuffed chicken breast and generously drizzle everything with the delicious, creamy pan juices. Enjoy!

FAQ
Q: Can I make this stuffed chicken breast dairy-free

Pro Tips
- Butterfly each breast by slicing horizontally and stopping about ½ inch from the edge — that keeps the pocket intact so the mushroom filling stays inside while baking.
- Don't dry it out: use a meat thermometer and pull the chicken at 165°F / 74°C, and pour the milk around the breasts so a creamy pan sauce forms as they bake.
- For an extra decadent touch, tuck a slice of provolone or a sprinkle of shredded mozzarella (dairy or dairy-free) in with the mushroom filling before folding the chicken closed.
- Store leftovers in an airtight container in the fridge for up to 3 days and reheat gently in the microwave or a covered skillet, spooning the pan juices over the top.
- Dietary swaps are easy: for dairy-free use non-dairy milk and avoid ghee; for AIP omit the black pepper; for coconut-free use avocado oil and a full-fat milk like cashew or oat.
