ingredients to make the mushroom stuffed chicken breast

how to make this mushroom stuffed chicken breast

  • First, cook the mushrooms: Heat 1 tablespoon of oil in a large non-stick pan or skillet over medium heat. Add garlic and mushrooms. Sauté stirring occasionally until mushrooms are tender. Lightly season with salt and pepper and set aside in a bowl together with all the juices.
  • Next, prepare the chicken: Cut a lengthways pocket to each chicken breast. Season the chicken breast with salt, pepper, and seasonings on both sides and into the pocket too.
  • Then, stuff the chicken: Stuff the pockets with mozzarella slices and sautéed mushrooms, then seal with a toothpick. It’s ok if you have any leftover mushrooms, we’ll add them later on to the sauce.

Cook the stuffed chicken breast

  • Heat the pan agaub and add in the remaining oil. Add chicken and sear until golden on both sides, about 6-8 minutes in total. Set aside on a plate.
  • Next, make the sauce: To the same skillet, add minced garlic and cook over medium heat for no longer than 1 minute, or until fragrant.
  • Add in the mustard, flour, and whisk for a bit. Pour the milk little by little, whisking after each addition to incorporate and form a thick sauce.
  • Once all the milk is added and there are no visible lumps, stir in the ground parmesan and season with a pinch of salt and pepper. If you have any remaining sautéed mushrooms and juices, now it’s the time to add them to your sauce.
  • Return chicken to pan with sauce: Next, return the chicken to the pan and into the sauce, and spoon the sauce over.
  • Let is cook: Cover the pan and cook over low heat for 12-15 minutes, or until the chicken is cooked through and the internal temp shows 165F.
  • Finally, garnish and serve: Garnish with freshly chopped parsley and serve warm.

Substitutes and tips

  • Almond Milk: You may use any other non-dairy milk, or 2% milk.
  • Use any other oil if needed like avocado or grapeseed oil.
  • You may use another white cheese in place of mozzarella like provolone.
  • Gluten-free flour can be replaced with any other flour.
  • Use freshly grated parmesan cheese for optimal flavor.
  • Cook over medium heat so the chicken cooks evenly and isn’t too dry and rubbery.
  • You may use another veggie in place of mushrooms.
  • Store leftovers in a tightly sealed container in the fridge for 3-4 days
  • Reheat in the microwave when ready to serve.

FAQ’s

Whats the best way to stuff chicken breast?

To stuff a chicken breast, you need to make pockets in the chicken breast so you are able to stuff it. The best way to do so is to lay the chicken breast flat on the cutting board and using a sharp knife slice right through the middle of the breast without slicing all the way through. Flip open the chicken breast, season it on both sides, and stuff it. Then using a toothpick, close the sides of the chicken breast and cook.

Can you cook or bake chicken breast with toothpick?

Yes. You can cook the chicken breast along with the toothpick. It is safe to cook and bake the stuffed chicken with the toothpick. Once your chicken is cooked, you simply remove them and throw away.

Should chicken be cooked on high or low heat?

Chicken should be cooked in low-medium heat. This will prevent your chicken from cooking too fast and drying out. The lower the heat the better to ensure juicy and tender chicken.

    Just made this for dinner and it was a huge hit! I used provolone instead of mozzarella, added chopped spinach to the mushroom/garlic mix before stuffing. I also added about 1/4c more of milk. Thanks for sharing!!

    Hi Rena,

    Made it with less mushroom but added asparagus and changed the cheese to parmesan. Just not fond of Mozz. It was awesome. Great reviews from company. Thank you so much

  3. I loved the recipe, except for the almond milk. I mistakenly used almond milk sweetened with vanilla. It had a strange taste. I’ll be sure to use regular milk next time!

  4. 4 stars
    Nice, tasty and moist., and recipe was easy to follow. A deviation- I mixed the mustard, flour and milk in a mug, then added to the pan- easy and all blended well that way. One suggestion- It might help to give a size or weight estimate for the chicken- I used two very large breasts, weighing about 1.5 – 2 lbs, and the recipe worked well for that quantity.

    This was really good. I loved the sauce and the recipe was easy to follow. I can’t say enough good things about it.

    Made it for lunch, and I loved it. Had a little issue with the flour (used AP) for sauce. It was a little thicker than it should’ve been. I’d recommend adding butter or a little oil, prior to adding mustard and flour.

        My family absolutely loved it! Sauce is so good and chicken is very tender! Thank you so very much!

        The family absolutely loved it! Definitely a new favorite in the house. I used garlic salt in place of regular salt and also used some butter on top of the olive oil while cooking and then again in the sauce. I also used cornstarch in place of the flour.❤️ Came out amazing!!!
