Slow Cooker Split Chicken Breasts with Onions and Mushrooms

Paleo Slow Cooker Chicken with Onions and Mushrooms

I found a great deal on some Split Chicken Breasts the other day so I bought them not knowing how I was going to use them. With most bone-in meats I prefer to use the slow cooker so I started my online research for slow cooker split chicken breasts to see how long I needed to cook them. Then I checked out the fridge to see what we had available and voila this recipe was born.

Ingredients and Substitutions

SPLIT CHICKEN BREASTS – Split chicken breasts are simply chicken breasts left on the bone. They are often available at your grocery store for cheaper than boneless chicken breasts. Because they have bone split chicken breasts will take longer to cook than boneless chicken breasts. This makes them ideal for cooking in the slow cooker. If you can’t find split chicken breast you can use bone-in chicken thighs.

MUSHROOMS & ONIONS – Buy presliced or slice your mushrooms. White button or baby portabella would work with this recipe. Thinly sliced yellow or sweet onions are best for this recipe.

CHICKEN BROTH – Store-bought or homemade chicken broth will keep the chicken moist while it cooks over a long period.
