Step-by-Step Instructions

🥄 Step 1: Prep the Chicken

1. Place the chicken breasts on a cutting board.

2. Use a sharp knife to cut a deep pocket horizontally into each chicken breast. Be careful not to cut all the way through.

3. Season the outside and inside of the pocket with:

   • Salt, pepper

   • Garlic powder

   • Onion powder

   • Italian seasoning

Tip: Pound the chicken to an even thickness before slicing to ensure even cooking.

🍄 Step 2: Make the Mushroom and Spinach Filling

1. In a large skillet, heat 1 tbsp olive oil or butter over medium heat.

2. Add minced garlic (and onions if using), and sauté for 2–3 minutes until fragrant.

3. Add the mushrooms and cook for 5–7 minutes until browned and softened. Season with salt, pepper, and red pepper flakes.

4. Stir in the spinach and cook until wilted, about 1–2 minutes.

5. Remove from heat and allow to cool slightly.

6. Stir in:

   • Shredded mozzarella

   • Parmesan cheese

Note: Cooling the mixture slightly prevents the cheese from melting prematurely while stuffing.

🧀 Step 3: Stuff the Chicken

1. Using a spoon or your hands, gently fill each chicken pocket with the mushroom-spinach-cheese mixture.

2. Secure the opening with toothpicks or tie with kitchen twine to prevent the filling from falling out during cooking.

Pro Tip: Don’t overstuff. Leave a little room to allow for the filling to expand slightly as it heats.

🔥 Step 4: Sear the Chicken

1. Heat the remaining 1 tbsp of olive oil in a skillet over medium-high heat.

2. Carefully add stuffed chicken breasts and sear for 2–3 minutes per side, just until golden brown.

This step adds flavor and helps seal the chicken. You’ll finish cooking it in the oven.

🍽️ Step 5: Bake

1. Preheat the oven to 375°F (190°C).

2. Transfer the seared chicken to a baking dish.

3. Optional: Sprinkle a little more mozzarella or Parmesan over the top for a cheesy crust.

4. Cover loosely with foil and bake for 20–25 minutes or until the chicken reaches an internal temperature of 165°F (74°C).

5. Remove foil for the last 5 minutes if you want more browning.

Optional: Broil for 1–2 minutes for a crispy top, but watch carefully!

👨‍🍳 Tips for Success

✅ 1. Don’t Overfill

It’s tempting, but too much filling can cause the chicken to burst during cooking.

✅ 2. Let It Rest

Rest the chicken for 5 minutes before slicing to let the juices redistribute.

✅ 3. Use a Meat Thermometer

Avoid under- or over-cooking. Chicken is done at 165°F in the thickest part.

✅ 4. Secure Properly

Use 2–3 toothpicks per breast if needed. Just remember to remove them before serving!

❓ Frequently Asked Questions

Can I use frozen spinach?

Yes! Just thaw and squeeze out all the excess water. Use about 1 cup of packed thawed spinach in place of fresh.

Can I make this dairy-free?

Yes. Use plant-based cheeses and olive oil instead of butter. Skip Parmesan or use nutritional yeast for a cheesy flavor.

Can I stuff thighs instead of breasts?

Absolutely! Use boneless, skinless chicken thighs and roll them around the filling, securing with toothpicks.

Can I make this in the air fryer?

Yes. Air fry at 375°F for 18–22 minutes. Flip halfway through. Use foil or parchment to prevent leakage.
