Tips For the Best French Onion Chicken

There is very little to get wrong in this simple recipe, but we always love to include tips from our kitchen to yours. This way, you’ll have the best experience possible with this tasty dish.

  • Quality Ingredients: Since there are only 5 ingredients in this whole recipe, each one is super important to get right. There is one caveat… If you love cheese, you can always add more!
  • White vs. Dark Meat: You can use boneless chicken thighs if you have them on hand and prefer to use them, however we prefer a large chicken breast instead. It holds up perfectly in the sauce and is easy to transfer to a casserole dish to melt the cheese on top.
  • Don’t Shred the Chicken: To keep the dish from being too salty, you should leave the chicken breasts whole. The sauce will season and flavor the chicken as it cooks, but if you shred the meat, it will soak up too much of the sauce and become overpowering.
  • Cheese: Melting the cheese on top makes a big difference to the final dish. It only takes a couple of minutes to pop the chicken under the broiler, and it makes this dish so much more French Onion Soup-y! Don’t skip this step!

How to Store & Reheat Crockpot French Onion Chicken

Leftover crockpot chicken is really easy to store and reheat. Here are our recommendations to keep them as fresh and tasty as possible.

  • Refrigerate: Store any leftovers in an airtight container in the fridge for up to 4 days.
  • Reheating: To reheat french onion chicken, place it in the microwave or warm in the oven at 350 degrees until heated through.
  • Freezing: Yes, you can freeze this recipe! Store your leftovers in an airtight container and freeze for up to three months. To serve, thaw in the fridge overnight then warm in the oven (350 degrees for 15-20 minutes) or until heated through. We prefer to freeze leftovers without cheese and then broil the cheese as normal once the chicken is warm.

    Made this last night and it was absolute perfection. Saw a comment about putting it on Italian bread before broiling and it was a great addition. Thank you for this excellent recipe!!

  2. 5 stars
    A family favorite! I have made this many times and it is so delicious and easy! Pairs wonderfully with mashed potatoes. I prefer the Swiss and lots of it! Thank you for the recipe 🙂

  3. Before I put the chicken in the pan to broil I layer the bottom of the pan with slices of italian bread.
    Truly delicious.
    Thank you for the recipe.

    1. Hi Dawne, We think it’s best if you freeze without the cheese and add cheese when you are ready to serve.
      Thanks! Ellen

  4. Hi. If I only want to make 2 chicken breasts, do I only put 1/2 packet & 1/2 can French Onion. Or keep the same as your recipe?
    Thank you.

    1. Hi Donna,
      Yes, 1/2 a packet and 1/2 a can of French onion would be best. You are going to love it 🙂

    Hi! Making this tomorrow and husband bought frozen chicken breasts in a bag. UGH! Do you think they will work?

    1. Hi Linda, I would let them thaw if possible. But yes you can use frozen, it may not be as flavorful because the chicken won’t soak up as much flavor. Thanks for following us 🙂

  6. We have thinner cut chicken breast strips instead of chicken breasts. Would they cook in about half the time?

    1. They will cook a little quicker, but still will take time in the slow cooker. If cooking on high, I’d check them around 2 to 3 hours!

  7. Could I use cream of mushroom condensed soup instead of French onion being I do not have French onion?

    1. Hi Brooke, You can change out the soup but cream of mushroom soup will change the flavor. Please let us know if you use cream of mushroom and how it turns out 🙂

    1. You can skip it, the cheese will warm from the hot chicken, but not totally melt. Or, you could quickly melt it in the microwave! Hope this helps!

  8. Made this tonight and it was so great to have dinner cooking during such a crazy day

    My entire family loved it and only one extra fish for sides! Thank you

    1. Hi Kristine,
      Yes! You can make French Onion Chicken in an Instant Pot 🙂
      You will need to cook for 20 minutes on high pressure and do a quick pressure release.
      Let us know how you like it!

    1. Hi Hannah! I think a 2.5 qt crock pot will be too small. You may be able to halve the recipe and make it work.
      If you do please let us know how it turns out.
      Thanks!

    I had six bone-in thighs from a Winn-Dixie deal in the freezer so I used them in the recipe, keeping everything else as-is. Four hours on high is definitely the way to go. Easy and delicious!

    1. You are right! Only 11
      I hope you love it as much as we do!

    1. Hi! You can use either, we like using a 6oz chicken breast for our family. Hope you enjoy as much as we do!

    Excuse me being dim…are you watering the condensed soup down or using it as it comes out of the can??

    1. Yes you can definitely use chicken broth! It’s a little less French onion soup flavor, but will still be tasty!

    1. Hi Shiah! This one I wouldn’t necessarily recommend for the instant pot because you would have to add more liquid to the instant pot for it to be able to reach pressure without burning. Which would really change the recipe, but if you want, you could add 3/4 cup water to the ingredients and cook it in the pressure cooker for 18 minutes at high pressure, with a quick pressure release. Hope this helps!

Hope this helps!

  11. What about doubling the recipe? Would you suggest not to? Or would it most likely work out the same?

    1. You should be able to double it with zero issues as long as you have a big enough crockpot for all those breasts!

        1. Hi Liz! Yes it should cook ok that way still! May just be a little extra soupy if you double it all! 😉

  12. How do you get the chicken to stay in one piece when done in a crockpot? Mine usually falls apart .. plan on making this tonight!

    1. Hi Maryjo! If yours is usually falling apart, I would recommend cooking it less time. Try 4 hours on high or try 6 hours on low! Your chicken is done cooking once it reaches 165°F internally which is much sooner than the standard 8 hours cook time!

    1. Hi Laura! You could also cook it in the oven, but FYI the chicken will not be as tender or soak up as much juice. But I would try cooking it slowly in the oven (with the casserole dish covered with foil) to hopefully let it marinate like it would in the slow cooker! Hope this helps!

      1. I have everything to make this for dinner tonight except for Swiss cheese. I have mozzarella I wonder if it would be as good??

  13. Just tried this last night and was a hit with my family. I served it with mashed potatoes and french bread with butter on it.

  14. We are super crazy for slow cooker meals right now! Love the hands off approach and I don’t have to turn on my oven!
