Ingredients

2 pounds chicken thighs (boneless, skinless recommended)
1 teaspoon kosher salt
1 teaspoon black pepper
1 tablespoon poultry seasoning (or Italian seasoning)
1 can condensed French onion soup
1 tablespoon Worcestershire sauce (or soy sauce)
2 cups beef broth (or chicken broth)
2 medium sweet onions, sliced (or yellow onions)
3 cloves garlic, diced
2 bay leaves
1 teaspoon fresh thyme (or dried thyme)
2 tablespoons salted butter (or unsalted butter)
1 cup Gruyère cheese (or Swiss or mozzarella)

Instructions

Step 1: Dry and season the chicken thighs generously with kosher salt, black pepper, onion powder, garlic powder, and poultry seasoning to create a flavorful base.
Step 2: Heat a skillet over medium-high heat and sear the chicken thighs for about 5 minutes on each side until golden brown. Transfer the chicken to your crockpot.
Step 3: Pour the condensed French onion soup, Worcestershire sauce, and beef broth into the hot skillet, scraping up any browned bits. Pour this mixture over the chicken in the crockpot.
Step 4: Layer the sliced sweet onions over the chicken, then add the diced garlic, bay leaves, fresh thyme, and butter on top.
Step 5: Cover and cook on low for 6 hours or on high for 4 hours, until the chicken is tender and easily breaks apart.
Step 6: Carefully transfer the chicken to a serving dish and top with Gruyère cheese. Broil in the oven for 3-5 minutes until the cheese is bubbly and browned.
Step 7: Serve with crusty bread, rice, or mashed potatoes for a complete meal. Optionally, garnish with additional thyme or parsley.

Tips & Variations

Use boneless, skinless chicken thighs for juicy, tender meat and easier cooking.
Sear the chicken before slow cooking to lock in juices and add flavor depth.
Substitute chicken breasts if preferred; adjust cooking time accordingly.
Add mushrooms or bell peppers for extra texture and nutrition.
Swap Gruyère for Swiss or mozzarella cheese to change the flavor profile.
Use chicken broth instead of beef broth for a lighter soup base.
For thicker sauce, stir a cornstarch slurry into the crockpot during the last hour of cooking.
Make it creamy by adding a splash of heavy cream or cream cheese near the end of cooking.
For gluten-free options, use gluten-free Worcestershire sauce and bread.

Storage

Store leftovers in an airtight container in the refrigerator for 3-4 days. Reheat gently on the stove or microwave, adding a splash of broth to keep the chicken moist. You can freeze cooled leftovers in airtight containers for up to 3 months. Thaw overnight in the fridge before reheating to a safe temperature of 165°F.

FAQs

What is the best way to select chicken for this recipe?

Boneless, skinless chicken thighs are best for this recipe as they stay juicy and tender during slow cooking. Look for bright pink, firm thighs without dark spots or odor. Chicken breasts can be used as a substitute but require less cooking time.

How should I store leftovers?

Place leftovers in airtight containers and refrigerate for up to 4 days. Warm gently on the stove or in the microwave, adding a little broth to keep the meat moist.

Can I freeze Crock Pot French Onion Chicken?

Yes, allow the cooked chicken to cool completely before freezing in airtight containers. It keeps well for up to 3 months. Thaw overnight in the refrigerator before reheating.

What should I do if my sauce is too thin?

Mix 1 tablespoon of cornstarch with 2 tablespoons of cold water to make a slurry. Stir it into the crockpot during the last hour of cooking and continue cooking on high until sauce thickens.

Are there any dietary considerations for this recipe?

To make it gluten-free, use gluten-free Worcestershire sauce and broth. For lighter options, swap beef broth for low-sodium chicken broth. Adjust or omit spices to accommodate allergies or preferences.

Can pets eat any leftovers from this dish?

It is safest to avoid feeding pets this dish due to onions and garlic, which are toxic to animals. Plain, unseasoned chicken without these ingredients could be given after consulting your veterinarian.
