Ingredients For This Mushroom Stuffed Chicken Breast

You’ll be surprised to discover that you can prepare a deeply delicious mushroom and spinach stuffed chicken breast with just a few common ingredients that will impress everyone.

  • Chicken Breast – It’s best to use bigger pieces of chicken breast that are large enough to be stuffed. You can also replace it with chicken thighs.
  • Butter – Unsalted one is the best. But if you use salted on, reduce the amount of salt you are using.
  • Mushrooms – you can use your favorite type of mushrooms. Either white bottom mushrooms or brown mushrooms are great to use.
  • Garlic – fresh minced garlic.
  • Baby Spinach – I like to use fresh baby spinach, but you can also use frozen one. Allow to defrost first, then mix into the mushroom sauce.
  • Mozzarella – You can use your favorite cheese, but trust me that when you see that melted mozzarella in your chicken breast, you will love it.
  • Thyme– my favorite herb to use for this mushroom stuffed chicken.
  • Salt & Pepper – To taste.
  • Olive Oil – For frying the chicken. If you want, you can use any other oil, such as avocado or grapeseed oil.

How To Make Mushroom Stuffed Chicken Breast

It’s so easy to make a delicious stuffed chicken breast recipe by following just some easy, simple steps. I cook it on those busy days since it’s so quick to prepare.

how to make mushroom and spinach stuffed chicken breast

1. Cut a slit in the center of each chicken breast to begin. You don’t want to cut all the way through, just a deep enough pocket for the stuffing. Season with salt and pepper.

2. Make The Creamy Mushroom Filling- In a large oven-safe pan, melt butter over high heat. Cook the mushrooms for 5 minutes, or until they get a golden brown color.

Sauté the garlic for one minute, then add the cream cheese and heavy cream. Add the spinach and cook until it wilts. Taste and season with thyme, salt, and pepper.

Tips For Making The Best Mushroom Stuffed Chicken Breast

  1. Don’t cut the chicken all the way through – Place the chicken on a cutting board and cut a deep pocket into the side with a sharp knife. 
  2. Make sure your chicken isn’t overcooked. In this case, a meat thermometer will be the best.
  3. Add some bacon or red pepper chili flakes into the stuffing.
  4. If you’re having difficulties filling the chicken, you’re not alone. Instead of using a spoon, fill the chicken with your fingers.
  5. Feel free to use your favorite veggies instead of mushrooms.
  6. For a thicker sauce, you can mix in a little xanthan gum or corn starch for gluten-free.

How To Clean The Mushrooms

In the beginning, you have to remove any damaged sections, any clumps of dirt, or thick, tough stems. 

Then wipe your mushrooms around with a moist paper towel to remove any dirt.

After you have followed all the steps, you can start cooking them.

How to Serve

There are so many great ideas to enjoy with this recipe. Here are my favorite ones:

How To Store Leftovers

  • Fridge: You can store the leftovers in the fridge for about four days in an airtight container.
  • Freezer: This is another fantastic way to keep this stuffed chicken recipe fresh. Make sure your chicken breasts are completely cooled down. Wrap them individually in plastic wrap and freeze them for up to three months.

 When you want to serve, reheat in a pan, add some water or butter, and heat the chicken over low heat until it is warm.

Can I Make This Recipe On Grill?

Sure, I love to make this recipe on the grill on those hot summer days.

All you have to do is follow the steps for preparing the chicken. First, wrap each stuffed chicken breast in foil and cook on a preheated grill for 8-10 minutes. You can also cook them in a large grilled pan over medium heat or until each side is thoroughly cooked through.
