This Slow Cooker Sweet Onion Chicken is a simple and versatile family supper that only requires a few inexpensive pantry staples. No matter how you serve it, everyone will love this warm, comforting meal!

Slow Cooker Sweet Onion Chicken

Don’t we all appreciate an easy and tasty slow cooker recipe? As you are well aware by now, my Crock Pot is one of my favorite kitchen appliances because there’s nothing better than tossing some ingredients together, setting the timer, and letting the machine do the rest of the work. It’s about all of the meal preparation I have time for these days, and with cooler fall temps on the horizon, my mind is turning towards cozy food!

We enjoy the chicken and onion sauce served over pasta, but it’s also delicious when it’s piled high on top of a crusty sub roll. Bonus points if you melt some cheese on top and pop the sandwich in the oven until it’s melty and brown! Of course, if your family prefers rice, that’s another great option. As I said, versatile is the name of the game, making left-overs that much more practical.

And thanks to the quick-cooking tapioca in the recipe (which has no taste), the sauce thickens up nicely and acts as a sweet and flavorful gravy for whatever your vehicle of choice! I find my tapioca in the Jell-O section of my grocery store.

    I love the sound of this, comforting but not too heavy. I’m collecting clow cooker recipes at the moment for the winter when I’m back at uni and don’t want to cook and I’ve already adding this to my collection =)

    I would totally eat this, but my oldest son hates onions, so I would have to omit that. Thanks for sharing on Merry Monday. BTW- my kids love the apricot chicken and said it’s a keeper 🙂

    1. Blair says:

      Hi, Erlene! So glad that your kids approved of the apricot chicken! 🙂
