Slow Cooker Chicken and Mushrooms

Creamy slow cooker chicken and mushrooms are a delicious dinner dish and are super easy to prepare.

Slow Cooker Chicken and Mushrooms

The creamy sauce cooks to be loaded with flavor thanks to the mushrooms, mustard, chicken, and herbs. The chicken itself takes on loads of flavor from the sauce and can be served whole or shredded.

Typically, I will serve one chicken breast per person. So, you should get roughly six or more servings out of a single batch of this recipe. I recommend cooking some side dishes to go with the chicken, for example, I love to serve it with noodles.

The leftovers of this dish will be great reheated for lunch or dinner the next day. I recommend keeping the leftovers in the refrigerator, but you can also keep them in the freezer. They should keep frozen for three months or three days in the refrigerator.

Adjusting the Recipe

There are lots of ways that you can tinker with this recipe. Below are just a couple of ideas on what you can do.

To make this a little cheesy and even creamier, you can add some cream cheese into the sauce. Roughly 250g (8 oz) of cream cheese will be more than enough. It will also thicken the sauce so you might not need the cornstarch mixture.

Any cut of chicken will work nicely in this recipe. I recommend chicken breasts, but something like chicken thighs or chicken drumsticks will also work.

You can tinker with the herbs in this recipe. I only use oregano, but other herbs like thyme or tarragon will work nicely with the rest of this dish’s flavors. Feel free to experiment a little to get the best flavors.

There are lots of other ways you can personalize this recipe. If you have a delicious adjustment that you want to share, then please do not hesitate to leave a comment at the bottom of this page.

What to Serve with Chicken and Mushrooms

Many different side dish combinations will work nicely with this meal. Below are a few ideas on how to serve this dish.

Some freshly cooked pasta will work very nicely with the creamy sauce and chicken. You can shred the chicken so that it works better with the pasta. I recommend cooking the pasta separate from the cream sauce for the best results.

Slow Cooker Chicken with Mushrooms and noodles

I love to serve this dish over the top of some homemade mashed potatoes. The creamy sauce of this dish and the mashed potatoes match perfectly. I always end up going back for seconds.

Steamed vegetables such as broccoli and cauliflower will work very nicely as a side dish. You can also make steak fries, herby baby potatoes, or sweet potato fries to go alongside the vegetables and chicken.
