"This easy crock pot french onion chicken is an ultra-flavorful recipe that’s perfect for meal prep and packed with nutrients," says Rachel Maser, mom of four and founder/creator of the clean eating blog, Clean Food Crush®. "A high-protein, incredibly flavorful, hands-off dinner that’s ready when you are!"

To make this slow-cooker chicken recipe you will need the following gluten-free ingredients: chicken breasts or thighs, onions, fresh garlic, Worcestershire sauce, balsamic vinegar, thyme (dried or fresh), bay leaves, sea salt, black pepper, chicken or beef bone broth and arrowroot powder (or gluten-free flour or cornstarch). Check out the health benefits of protein.

"This recipe is gluten-free as long as you’re using arrowroot powder (which is naturally gluten-free), gluten-free cornstarch (some cornstarch contains trace amounts of gluten) or gluten-free flour," says Rachel. "Alternatively, you may decide to skip the slurry/thickener altogether which is still delicious but a thinner sauce."

Rachel likes to serve this high-protein recipe over mashed cauliflower, mashed potatoes, quinoa or brown rice. This is a wonderful meal-prep recipe, too.

Cook Time: 3 to 4 hours (low) or 6 to 7 hours (high)
Total Time: 10 minutes plus 3 to 7 hours
Servings: 6

Ingredients

• 2 pounds boneless/skinless chicken breasts or chicken thighs
• 3 - 4 large sweet onions, thinly sliced
• 4 garlic cloves, minced
• 3 tablespoons Worcestershire sauce
• 2 teaspoons balsamic vinegar
• 1 tablespoon dried thyme or fresh thyme
• 3 bay leaves
• 1/2 teaspoon sea salt
• 1/2 teaspoon fresh ground black pepper
• 1 cup beef bone broth or chicken bone broth
• 2 tablespoons fresh parsley, chopped, for garnish (optional)

Slurry to Thicken Sauce

• 2 tablespoons arrowroot powder (or gluten-free flour or cornstarch)
• 3 tablespoons water or bone broth

Here's how to make it: 

1. Add chicken to your slow cooker. Add the sliced onions, garlic, Worcestershire, balsamic and all the seasonings. Pour in the bone broth. Stir to combine.
2. Cover and cook on low for 6 to 7 hours or high for 3 to 4 hours, or until chicken is fully cooked and the internal temperature reaches 165 degrees F on a food thermometer. (Rachel cooked on low for 7 hours and her chicken was falling apart.)
3. Remove bay leaves. Using two forks, gently shred your chicken a little bit. Return the shredded chicken to your onion sauce.
4. Whisk the arrowroot (or flour or cornstarch) with your water or bone broth until smooth to create a slurry. Stir in your slurry the last 10 minutes of cooking to help thicken up the sauce.
5. Garnish with fresh parsley, if desired.
