How to Make Crock Pot French Onion Chicken

Prepare Chicken: Pat the chicken thighs dry with a paper towel, then season generously with kosher salt, black pepper, onion powder, garlic powder, and poultry seasoning to ensure full flavor.
Sear Chicken: In a skillet, heat a drizzle of oil over medium heat. Sear the chicken thighs skin-side down for about 5 minutes until golden brown and crispy. This step adds flavor and texture!
Create Flavor Base: Carefully deglaze the skillet by adding the French onion soup, Worcestershire sauce, and beef broth. Scrape any browned bits off the bottom for extra flavor, letting it simmer for a few minutes.
Layer in Slow Cooker: In your slow cooker, place the seared chicken thighs. Add sliced sweet onions, the deglazed mix, minced garlic, bay leaves, fresh thyme, and pats of butter scattered throughout.
Cook: Cover and cook on low for 6 hours or high for 4 hours, until the chicken is fork-tender. This slow cooking allows the flavors to meld beautifully!
Finish with Cheese: For a gourmet touch, transfer the chicken to an oven-safe dish, top with Gruyère cheese, and broil for 3-5 minutes until bubbly and golden. Alternatively, add the cheese to the slow cooker during the last hour on low for a melty finish.

Optional: Serve with crusty bread for dipping into the flavorful broth.

Crock Pot French Onion Chicken Recipe FAQs

What type of chicken is best for this recipe?

When you’re ready to enjoy it, thaw it in the fridge overnight and reheat until it reaches an internal temperature of 165°F for safe consumption.

What should I do if my chicken is tough after cooking?
If your chicken ends up tough, it might not have cooked long enough or was overcooked. Make sure to cook it for the full duration—the chicken should be fork-tender after 6 hours on low or 4 hours on high. For next time, consider using a meat thermometer; the internal temperature should reach 165°F for optimum doneness!
