Slow Cooker French Onion Chicken – Boneless chicken breasts are topped with gooey Swiss cheese on a bed of thinly sliced onions in this crock-pot French onion chicken recipe.
The crock-pot does all the work of coaxing the onions into a caramelized state, a task that would take at least 30 minutes on the stove top while you babysit them the entire time, maybe longer.
If you never had a caramelized onion before then you are sincerely missing out on something special and you absolutely have to make this.
Thinly-sliced yellow onions are mixed with melted butter, Dijon, Worcestershire, a touch of sugar, salt and pepper plus a little flour to help thicken the flavorful juices that come out of them as they cook so you can spoon it over the chicken.
Slow-cooking the chicken causes it to be so tender you can slice through it with a fork. Just like butter.
Get this in your crock-pot in the morning and sit down later to one of the easiest, most comforting and delicious meals ever.
