Ingredients You’ll Need

Everything you need for this recipe is refreshingly simple but works harmoniously to create those comforting, layered flavors and textures. From the earthy mushrooms to the melty mozzarella and delicate thyme, each ingredient has an important role to play.

• 2 chicken breasts (220g or 7oz each, skinless and boneless): The perfect protein canvas for stuffing and soaking up flavors.
• 3/4 teaspoon salt: Enhances all the natural flavors without overpowering them.
• 1/4 teaspoon black pepper: Adds a subtle hint of heat and depth.
• 2 tablespoons unsalted butter (30g): Creates a rich base for cooking the mushrooms and garlic.
• 7 oz mushrooms, sliced about 1/8″ thick (approximately 2 full cups, 200g): The heart of the filling, delivering earthiness and moisture.
• 2 cloves garlic, finely minced: Brings fragrant warmth and a little zing.
• 1/2 teaspoon thyme leaves: Offers an herby brightness that lifts the mushrooms.
• 2 cups fresh baby spinach: Adds freshness, color, and a subtle vegetal sweetness.
• 3 oz mozzarella cheese, sliced (or any cheese that melts well, 80g): Melts beautifully to bind everything together with creamy goodness.
• 1 tablespoon olive oil: For that essential sear and crisp, golden exterior.

How to Make Mushroom Stuffed Chicken Breast

Step 1: Preheat Oven and Prepare Chicken

Start by warming your oven to 200°C (390°F) or 180°C fan-forced, creating the ideal environment for perfectly cooked chicken. While the oven comes up to temperature, take each chicken breast and gently slice a pocket into the side. The goal is to open up a little space for the filling without cutting all the way through, keeping the outside smooth and intact. Don’t forget to season both inside and out with half the salt and pepper—this seasoning inside the pocket ensures every bite bursts with flavor.

Step 2: Prepare the Mushroom Filling

Heat a heavy-based, oven-safe skillet over high heat and melt the butter. Toss in the mushrooms and give them about three minutes to soften and start turning golden. Next, sprinkle in the garlic, thyme, and the rest of your seasoning, stirring well as the mushrooms continue to cook and develop a rich color. Finally, add the fresh baby spinach and cook just until it wilts—very fast, around 30 seconds—so it retains its vibrant green color and slight crunch.

Step 3: Stuff and Seal the Chicken

Now comes the fun part. Carefully fill each chicken breast pocket with the fragrant mushroom and spinach mixture, distributing it evenly. Top the filling with slices of mozzarella to add that irresistible creamy melt when baked. Secure the opening with toothpicks—no need for a perfect seal, just enough to keep most of the filling inside as it cooks.

Step 4: Sear the Chicken

Wipe your skillet clean to remove any excess butter and residues. Warm the olive oil over medium-high heat, then gently sear the stuffed chicken breasts on each side for about 90 seconds. This quick sear locks in juices and creates that gorgeous golden exterior that will have everyone’s mouth watering before the baking even starts.

Step 5: Bake the Chicken

Transfer your skillet to the oven and bake the chicken for around 15 minutes, or until the internal temperature of the chicken reaches 65°C (149°F). Using a meat thermometer is the best way to ensure the chicken is perfectly cooked without drying out. Be sure to measure the temperature of the chicken meat itself, not the filling, for accuracy.

Step 6: Rest and Serve

Once baked, take the skillet out and transfer the chicken to a plate, letting it rest loosely covered with foil for about five minutes. This rest time allows the juices to redistribute, keeping the chicken moist and tender. Serve warm with your favorite sides for a meal that’s equal parts cozy and impressive.

How to Serve Mushroom Stuffed Chicken Breast

Garnishes

A sprinkle of freshly chopped parsley or thyme leaves on top adds a pop of fresh color and herbal fragrance that complements the mushroom filling brilliantly. For a touch of indulgence, drizzle a little truffle oil just before serving to elevate the umami notes.

Side Dishes

Mushroom Stuffed Chicken Breast pairs beautifully with creamy sides like a lemon herb risotto or buttery mashed potatoes. If you want something lighter, a crisp baby spinach salad dressed with balsamic vinaigrette makes a refreshing contrast to the richness of the stuffed chicken.

Creative Ways to Present

For a stunning presentation, slice the stuffed chicken crosswise to reveal the colorful mushroom-spinach-cheese filling spiraled inside. Arrange slices on a platter with some roasted cherry tomatoes and fresh herbs for a restaurant-worthy look that’s bound to impress your guests.

Make Ahead and Storage

Storing Leftovers

Leftover Mushroom Stuffed Chicken Breast keeps well in an airtight container in the refrigerator for up to 3 days. Keep toothpicks in place while storing to ensure the filling stays put when reheating.

Freezing

You can freeze cooked stuffed chicken breasts by wrapping them tightly in plastic wrap and placing them in a freezer-safe container or bag. They’ll maintain the best quality for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

To enjoy leftovers, reheat gently in a low oven at 160°C (320°F) for about 10-15 minutes, or until warmed through. This method helps preserve moisture better than microwaving, which can dry the chicken out.

FAQs

Can I use other types of mushrooms for the filling?

Absolutely! Any mushrooms you enjoy will work well, such as cremini, shiitake, or portobello. Just slice them thin so they cook evenly and blend nicely with the other ingredients.

What cheese can I substitute for mozzarella?

Feel free to swap mozzarella with fontina, provolone, or even Swiss cheese—choose one that melts smoothly and adds a creamy texture to the filling.

Is it necessary to use toothpicks to seal the chicken?

While not absolutely crucial, toothpicks help keep the filling inside during cooking and make it easier to handle the stuffed chicken without losing precious filling.

Can I prepare the Mushroom Stuffed Chicken Breast ahead of time?

Yes! You can assemble the chicken breasts with their filling a few hours ahead and keep them refrigerated. Just sear and bake them when you’re ready to eat.

How do I know when the chicken is fully cooked?

The safest way is to use a meat thermometer. The internal temperature should reach 65°C (149°F) in the thickest part of the chicken, away from the filling, to ensure it’s cooked through but still juicy.
