Crock Pot French Onion Chicken

Crock Pot French Onion Chicken is a delicious meal that combines the savrory flavors of classic French onion soup with fall off the bone, juicy chicken.

This dish is perfect for those busy days when you want a warm, satisfying dinner without spending hours in the kitchen. With simple ingredients like onions, chicken thighs, beef broth, and a touch of Worcestershire sauce, this recipe is as easy to prepare as it is flavorful. 

When it’s time to serve, the chicken is topped with a layer of gooey cheese, melted to golden perfection. It’s a comforting, crowd-pleasing recipe that the whole family will LOVE. And when you pair it with crusty bread or garlic bread to soak up the broth, it’s a flavor explosion! 

(full list of ingredients can be found in the recipe card)

• Chicken Thighs are my preference because they’re tender and juicy and don’t dry out. You can use chicken breasts, but my recommendation will be the thighs for this recipe! Use leftovers and make my creamy chicken wild rice soup or sheet pan chicken thighs next.
• French onion soup mix infuses the dish with concentrated flavors of onions, herbs, and seasonings, enhancing the depth and complexity of the sauce. It also simplifies preparation by providing a quick and convenient way to achieve the classic French onion flavor profile.
• Condensed French Onion Soup adds a rich, savory flavor, providing a deep onion base that complements the chicken perfectly. It also creates a velvety sauce as it cooks, soaking into the chicken and enhancing its tenderness.
• Low Sodium Beef Broth, along with the french onion soup, are the base of the broth. I add the beef broth so that the dish isn’t overly salty. 
• Sweet onions add a natural caramelized sweetness and depth of flavor. You can use yellow onions or shallots as a good substitute.
• Gruyère cheese melts into a creamy, luxurious topping with a nutty, tangy flavor that balances the sweetness of caramelized onions. It also creates a golden, bubbly crust reminiscent of classic French onion soup. You can also use mozzarella cheese as a substitute. 
• Worcestershire sauce enhances the savory flavors, adding a umami-rich, tangy, and slightly sweet flavor.
• Bay leaf, thyme, garlic are essential to adding a lot of flavor to that french onion gravy as it cooks in the crockpot.

How to make Slow Cooker French Onion Chicken

Step 1: Pat the chicken thighs dry with a paper towel and place into a large bowl. Season with kosher salt, black pepper, garlic powder, and poultry seasoning. Drizzle olive oil into a 12-inch nonstick skillet over medium high heat. Place the chicken thighs into the pan and sear on both sides for 5 minutes per side, until golden brown. Remove from the pan and reduce heat to low.

Step 2: Add condensed french onion soup, Worcestershire sauce, and beef broth into the pan to deglaze the pan. Use a wooden spoon or rubber spatula to scrape the bits off of the bottom of the pan, then pour into the crockpot. 

Step 3: Add sliced onions to the bottom of the crockpot. Place chicken on top of the onions, then sprinkle french onion soup mix on top. Pour the soup/broth mixture and add diced garlic, bay leaves, thyme, and sliced butter on top. Cover with the lid and cook on low heat for 6 hours, until the chicken is tender and falls off of the bone. (you can also cook on high heat for 4 hours, but I recommend low heat for best results)

Step 4: Remove the chicken along with the juices and onions and add back into a casserole dish or large oven safe skillet Coat with shredded gruyere cheese and broil in the oven for 3-5 minutes, until the cheese melts and becomes golden brown. (You can also add the cheese to the crockpot and continue to cook for an additional hour) Serve with crusty bread and mashed potatoes or white rice for the ultimate comfort meal. 

​Foolproof Tips

• Cook Low and Slow: For the most tender, flavorful chicken, cook on the low setting for 6-8 hours. While the high setting is faster, the low setting allows the flavors to fully develop and ensures the chicken stays moist.
• Choose the Right Chicken: Boneless, skinless chicken breasts or thighs work best for this recipe. Thighs are less likely to dry out, but if you prefer breasts, keep an eye on cooking time to avoid overcooking. For added flavor, sear the chicken  before placing it in the crock pot.
• For thicker gravy, omit the beef broth. If you like the extra gravy, make a cornstarch slurry by combining 1-2 tablespoons cornstarch and 2 tbsp water to a small bowl. Mix together and add to the broth halfway through the cooking process, stir, and continue cooking.
• Ensure the fresh herbs ​are the submerged in the broth – the heat is what extracts the flavors.
