Why You’ll Love Slow Cooker French Onion Chicken
French onion soup and tender pot-roasted chicken is the perfect combination. The slow cooker does the heavy lifting, onions melt into gold-brown ribbons while the chicken soaks up every herb-balsamic flavor.
A final blanket of Swiss cheese turns the savory broth into a gooey, irresistible gravy. Make sure you pick up a loaf of crusty garlic bread to dip into the delicious broth. If you have extra time, make these easy Homemade Dinner Rolls.
Bread is a must because you will want to dip the bread into the broth to get every last drop. This is the ultimate comfort food that the entire family will love.

How to Make Crockpot French Onion Chicken
Step 1 – Prepare Crockpot – Even though it is not necessary, you can spray you crock pot with cooking spray.

Step 2 – Add onions – We like to add the onions first to the bottom of the slow cooker. We love caramelized onions and adding them first really brings out the flavor of the sweet onion. Add the chicken breast and place on top of the onion. Season the chicken breast with salt and thyme. Pour the Balsamic and the broth over the top.

Step 3 – Cook on low for 8 hours or high heat for 4 with the lid stirring occasionally. Cooking time could vary. 30 minutes before serving, top with the slices of Swiss cheese.
Step 4 – Melt the Cheese – Cook for 15 minutes to 30 minutes or until the cheese is melted. Spoon the onion mixture on top of the tender chicken and serve.

Tips for the Best French Onion Chicken
- Add all the ingredients – All the ingredients combine together makes it the reason this is the most flavorful chicken. The only thing I would add is more cheese if you are a cheese lover like we are.
- Skip on shredding the chicken – Most of the time when we make chicken in the crock pot, it always seems we shred it. But this recipe, we always keep the chicken breast whole. Shredding the chicken absorbs all the liquid.
- French Onion Gravy – We love the gravy that is made with the onion, balsamic vinegar and broth. It is perfect pour over the chicken and perfect dipping your favorite bread.
Variations for French Onion Chicken
- Use another cut of Chicken – You can use chicken thighs instead of chicken breast if you prefer.
- Cheese Alternative – If you do not like swiss cheese, you can also use provolone cheese or mozzarella cheese. You can also use gruyere cheese. But it can be hard to find so a good alternative is provolone.
- Add Mushrooms – If you love mushrooms as much as my sister does, then I would add them to this recipe.
- Use Red Onions – Use red onions instead of the Vidalia onions if you prefer. Yellow onions is also a great alternative.
- Cook the Onions – Some recipes called for cooking the onions in a skillet prior to adding them to onions. It is your preference, but I like just adding them to the crock pot.

- Reheat – Place the leftovers in a baking dish and reheat in the oven or in the microwave until heated through.

I canned with homemade beef broth some onion soup. My question is how could I use it in this? I was thinking maybe strain my soup and put those onions on bottom then follow the rest of the recipe. What do you think.
Please and thank you for your recipes and time. Blessings
I think you can use it with the broth. I would just eliminate the broth in the recipe.
I thought I would try this recipe because I have always loved French onion soup. The whole time is was cooking it smelled so delicious I couldnโt wait to eat it. Turns out that my whole family loves it. It has become a regular dish in our house now.
Definitely making again. Easy, delicious & budget friendly, can’t beat that..thanks for sharing ?

Can a different cheese be substituted? I do not like Swiss cheese. I would prefer a mozzarella or provolone if possible.
Why beef broth? Is it ok to use chicken broth instead?
