Hearty, comforting, and perfect for cooler weather, this Slow Cooker French Onion Chicken is a family favorite! Complete with tender baby potatoes, slow caramelized onions, and shredded Gruyere cheese, this is a one-pot chicken thigh meal you’re going to love having on rotation.
So my question of the day today is: are you a soup lover, hater, or tolerator?
As for myself, I’m a soup tolerator. I really have to be in a particular mood to enjoy soup (unless it’s tomato bisque with a grilled cheese – in which case, I’m eternally interested.)
One type of soup I’ve never been a freak over is French onion.
Don’t get me wrong – I love caramelized onions more than some of my family members. I’d honestly rather just eat them with a fork than in a thin broth.
Adding them to an easy one-pot chicken dinner, though, was almost a stroke of genius. One that might make me reconsider this whole “soup mood” thing.

After many years of preferring white meat chicken, I’ve finally turned to the dark side. Chicken thighs became my obsession over the summer, and it looks like it’s one that’s gonna keep on keepin’ on into the colder months.
I hope that’s OK!

Do You Have To Brown Chicken Before Slow Cooking?
You DO NOT have to brown chicken thighs before slow cooking them, but they will taste SO much better if you do! Searing meat before slow cooking, especially poultry with skin, helps it develop delicious, deep flavor it wouldn’t otherwise.
Browning/searing is a quick process, and shouldn’t take more than 4-5 minutes for both sides of a chicken thigh. Dark meat chicken tends to stay moist longer than white meat, but you still don’t want to overcook it before it even goes into the slow cooker.
Can You Put Raw Chicken In A Slow Cooker With Vegetables?
Yes, you can cook raw chicken with vegetables in a slow cooker. Everything cooks together to a temperature that kills any bacteria that may have lived on the chicken (165 degrees F).
However – this is another good reason to brown your meat before slow cooking. If you have concerns about this subject, searing the chicken on high heat prior to adding it to the slow cooker will kill any bacteria living on the chicken skin.
How Long Does It Take To Cook Chicken Thighs In A Slow Cooker?
On low heat, it will take 5-6 hours to cook chicken thighs. On high heat, 3-4 hours will do the trick.
Make sure the internal temperature inside the thickest part of the chicken is 165 degrees F before eating it.
How To Make Slow Cooker French Onion Chicken:
- First, pre-caramelize your onions in butter over medium heat. This initial browning will add all kinds of delicious flavors to the final dish.
- Then, transfer the onions to your slow cooker and sear the seasoned chicken thighs over high heat, 4-5 minutes, until lightly browned on both sides.
- Next, add baby potatoes, chicken broth, garlic, and herbs to the slow cooker. Stir it all together with the onions, then lay the chicken thighs on top of everything.
- Close the lid and slow cook for 4 (high) to 6 (low) hours until chicken is cooked through to temperature.
- Finally, lay slices or shreds of Gruyere cheese on top of the chicken. Close the lid and allow it to melt for 4-5 minutes more before serving with potatoes and onion broth.

If I can’t find Gruyère cheese, what is the best cheese to substitute it?
Hi Maggie! Any type of good, melty cheese should work similarly – I would try muenster, Gouda, or maybe Monterey Jack. 🙂 Whichever suits your tastebuds!
