How To Make Easy Slow Cooker Chicken Marsala Recipe

Slow Cooker Chicken Marsala Recipe
Written by The Protein Chef

The warmer weather is finally here and if you’re not at the grill you probably don’t wanna spend hours prepping meals inside. This Slow Cooker Chicken Marsala recipe is super easy and quick to prep, you get a lot of bang for your buck, and the macros are awesome!

Start this one by trimming the fat off of 3 pounds of chicken breast and then cut them in half length wise (1/4” thick or so). This next step is optional…but preferred. Season them with a little salt & pepper, add some oil into a pan, and cook your chicken on both sides for a couple minutes.

Line your slow cooker for easy clean up and add your chicken into it. Follow that with 1 cup of chicken broth, 1 tablespoon of minced garlic, 1 cup of marsala cooking wine, and 2-3 cups of some sliced mushrooms (I like a mix of portobello and white). Throw your lid on and slow cook it on low for around 4 hoursif you cooked it or 5 hours if you didn’t.

After 4 hours remove your chicken and mix together 8 tablespoons of corn starch and 2/3 cup of water. Pour that in with 1 tablespoon of Italian seasoning and mix everything together until smooth. Put your chicken back in and slow cook it on high for 30-40 minutes or until your sauce thickens up.

Last add in 1/2 cup of heavy cream, 1/4 teaspoon of salt, and 1/4 teaspoon of black pepper. Lightly mix and you should get something like this…

I usually portion this one out into 6 servings and each serving is usually around 500 grams. This number can vary so just use it as a rough estimate.
