1 cup chicken broth: Enhances the flavor of the sauce.
1 medium onion, diced: Sweet and savory, it’s a must for the sauce.

How to Make Creamy Mushroom Chicken with Mashed Potatoes 🥔🍗

Prepare the Mashed Potatoes:
- In a large pot, bring water to a boil. Add the diced potatoes and cook until tender, about 15-20 minutes. Drain and return the potatoes to the pot.
- Add milk, butter, salt, and pepper to the potatoes. Mash until smooth and creamy. Set aside.
Cook the Chicken:
- In a large skillet, heat olive oil over medium heat. Season the chicken breasts with salt and pepper. Add them to the skillet and cook until browned and cooked through, about 6-7 minutes per side. Remove the chicken from the skillet and set aside.
Prepare the Mushroom Sauce:
- In the same skillet, add the diced onion and sauté until translucent, about 3-4 minutes. Add the minced garlic and sliced mushrooms, cooking until the mushrooms are tender.
- Pour in the chicken broth and heavy cream. Stir in the thyme and simmer the sauce until it thickens slightly, about 5-7 minutes.
Combine and Serve:
- Return the cooked chicken to the skillet, spooning the mushroom sauce over the top. Cook for an additional 2-3 minutes to heat through.
- Serve the creamy mushroom chicken over a bed of mashed potatoes and enjoy!

Substitutions & Additions

You can use turkey breasts instead of chicken for a delicious twist.
Swap out the heavy cream for half-and-half or a plant-based cream for a lighter version.
Add fresh spinach or kale to the mushroom sauce for an extra boost of nutrition.

Tips for Success

Be sure to not overcrowd the skillet when cooking the chicken; this helps it brown nicely.
If your sauce is too thick, you can thin it out with a bit more chicken broth.
For a make-ahead option, prepare the mashed potatoes and mushroom sauce a day in advance. Just reheat and combine when ready to serve.

How to Store Creamy Mushroom Chicken with Mashed Potatoes 🥔🍗

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave. If you have leftover mashed potatoes, they can be stored the same way, but they may need a splash of milk to bring back their creamy texture when reheating.

FAQs

Can I freeze this dish? Yes, you can freeze the chicken and sauce together, but it’s best to freeze the mashed potatoes separately. They may change texture when thawed.
