This recipe came together by what I had in the pantry.

What to serve with French Onion Chicken?

There are a lot of options and it depends on if you would like to keep this a low carb meal or not. Here are a few of my favorites!

Low Carb Side Recommendations:

Traditional Side Recommendations:

  • Mashed Potatoes
  • Crusty Bread (to soak up the sauce)
Ingredients arranged on countertop with chicken breasts on a plate.

Just 5 Ingredients

This recipe needs only 5 simple ingredients! You’re going to be very pleased with how easy this chicken dish is to make. Just gather up the ingredients listed below to get started!

  • Boneless skinless chicken breast
  • Yellow onion, sliced
  • Can condensed french onion soup
  • Lipton Onion Soup & Dip Mix
  • Swiss or Gruyere Cheese

Can I use another cut of chicken?

Yes! You can use boneless chicken thighs if you have them on hand and prefer to use them, however I personally 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.

I don’t like Swiss cheese, what else can I use?

To keep it most similar to French Onion Soup, I recommend you use a cheese like the classic gruyere cheese. However gruyere cheese can get expensive and isn’t sold in slices, so that’s where Swiss cheese comes in. If you really don’t like Swiss cheese and can’t get gruyere instead, you can also use provolone or mozzarella.

How to make french onion chicken in the crockpot:

  1. Prepare: Spray a large crockpot with nonstick spray. Arrange chicken breast in an even layer on the bottom of the crockpot.
  2. Combine: Layer sliced onions on top of the chicken and sprinkle with Lipton onion soup & dip mix. Pour French onion soup on top and place lid on the slow cooker.
  3. Cook: Cook for 4 hours on high or 8 hours on low.
  4. Preheat: Preheat broiler and grease a casserole dish with nonstick spray.
  5. Arrange: Remove whole chicken breasts and place them in an oven-safe casserole dish. Scoop out any leftover cooked onions and arrange those on top of the chicken.
  6. Serve: Top each chicken breast with cheese and broil until melted and bubbling, about 2 minutes. Serve immediately!

Tips for the best crockpot chicken!

  • Don’t skimp on any of the ingredients! Since there are only 5 ingredients in this whole recipe, each one is super important to have correct. Although, if you love cheese, you can always add in more. I’m a firm believer that you can never have too much cheese! 
  • Do not shred your chicken, keep the breasts whole. If you shred the chicken, it will become too salty. Cooked in the sauce the chicken will have great seasoning and flavor, but if you shred the meat it will absorb too much of the sauce and it will become salty fast!

How to store leftovers:

If you happen to have any leftovers of this chicken, store it in an airtight container in the fridge for up to 3 to 4 days. You can reheat it in the microwave or oven as desired!

    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!

      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!
