Slow cooker French onion chicken is a cozy, no-fuss dinner made with tender, shredded chicken and rich, savory onion flavor. It’s a low-effort meal that’s perfect for busy weeknight meals.

I love recipes that let me get dinner started and then completely forget about it. Slow cooker French onion chicken has become one of my go-to meals on busy days when I still want something comforting on the table. It uses simple pantry ingredients, but the flavor tastes as if you put in way more effort than you actually did.
What really sold me on this recipe is how tender the chicken turns out every single time. I’ve made it on days when I knew I’d be running around nonstop, and coming home to shredded, creamy chicken felt like a small win. The onion soup mix gives it that deep, savory flavor without needing extra seasoning, which makes it incredibly beginner-friendly.
I also love how versatile this dish is once it’s done cooking. I’ve served it over rice, spooned it onto mashed potatoes, and even used leftovers for sandwiches the next day. If you’re someone who wants easy comfort food with minimal prep and reliable results, this is the kind of slow cooker recipe you’ll want to keep in rotation.
Items Needed

Here’s what you’ll need to make slow cooker French onion chicken:
- Boneless chicken breasts – They cook up tender, shred easily, and soak up the savory flavors during slow cooking.
- Unsalted cream of chicken soup – It creates a rich, creamy base while letting the onion soup mix control the salt level.
- Onion soup mix – This adds deep, classic French onion flavor without needing extra seasonings or chopping onions.
- Chicken stock – It thins the sauce slightly and enhances the overall savory taste as the chicken cooks.
Tools you’ll need
Before starting the recipe, you’ll want to have all your kitchen essentials ready. I recommend having the following items:
Ways To Customize
Here are some easy ways to customize this recipe without adding extra work:

- Switch the protein – Use boneless chicken thighs for even juicier results.
- Turn up the herbs – Add dried thyme or parsley for extra depth.

How To Make It

Place chicken in the slow cooker.

In a bowl, whisk together soup, onion soup mix, and broth, then pour over the chicken.

Cook on HIGH for 4 hours.

Shred the chicken.
Note
Avoid adding extra salt, since the onion soup mix already contains plenty, and the flavors concentrate as the chicken cooks in the slow cooker.

Storage
Store leftover chicken in an airtight container in the refrigerator, where it will keep well for up to four days. To reheat, warm it gently on the stovetop or in the microwave, adding a small splash of chicken stock if needed to loosen the sauce and keep the chicken moist.
Helpful Hints
Pro tip: Sear for Flavor!
For extra flavor, sear the chicken briefly in a hot skillet before adding it to the slow cooker. This adds a subtle caramelized taste that makes the dish even more savory.
More Cooking Tips:
- Don’t lift the slow cooker lid while cooking, as it can extend the cooking time.
- Use boneless, skinless chicken thighs for easy shredding.
- Stir the sauce well before serving to evenly coat the chicken.
- Add vegetables like mushrooms or carrots for a one-pot meal.
- Let the chicken rest a few minutes after shredding so it absorbs the sauce better.

Serving Suggestions
One of my favorite ways to serve slow cooker French onion chicken is over a bed of fluffy rice. The creamy, savory sauce soaks into the rice, making every bite rich and comforting. You can use white, brown, or even cauliflower rice if you want a low-carb option, and it’s perfect for soaking up every bit of the flavorful sauce.
Another great option is to serve it over mashed potatoes. The tender shredded chicken pairs beautifully with the creamy, buttery potatoes, creating a classic comfort food combination. I like to spoon extra sauce from the slow cooker on top—it makes the dish feel indulgent without any extra effort. You can also sprinkle a little fresh parsley or thyme for a pop of color and freshness.
If you want something quick and portable, try using the chicken for sandwiches or sliders. Toast some rolls or buns, pile on the shredded chicken, and drizzle with extra sauce for a juicy, flavorful sandwich. This is also a great way to use leftovers, and adding a slice of cheese or caramelized onions takes it to the next level. It’s a simple way to turn one slow cooker meal into multiple delicious meals.
