    Slow Cooker French Onion Chicken

    If you love the taste of french onion, you’re going to love this french onion chicken recipe!

    French onion chicken is so good. It’s the best thing on my menu, along with chicken parmesan and my teriyaki salmon bowl (my fourth favorite…but I digress). I make this recipe at least twice a month if not more. It never gets old, and it’s absolutely amazing when paired with mashed potatoes and sauteéd green beans or asparagus.

    Recipe Tips & Variations

    • Can add breadcrumbs to chicken for more crunch.
    • If you don’t have swiss cheese or don’t like it you can replace it with Gruyere cheese.
    • Vidalia onions work great in this recipe but can also use sweet onions instead.
    • Serve with potatoes, rice, egg noodles and/or cooked vegetables for a complete meal.

    Other Ways to Cook French Onion Chicken

    Casserole Method

    Preheat oven to 400 F degrees. Spray a 9X13 baking pan with cooking spray. Add butter to a pan and melt over medium high heat. Add onions and garlic and cook for 5 minutes. Reduce heat to medium and add in beef broth and cook until onions and garlic are caramelized.

    Season chicken with salt, pepper and thyme. Cook over medium heat until there is no more pink. Pour half of caramelized onions/garlic mixture and broth on the bottom of a baking dish. Place chicken on top. Pour the remaining caramelized onions/garlic broth mixture over top. Sprinkle dry onion soup packet and place cheese on top. Bake uncovered for 30 minutes or until the chicken reaches an internal temperature of 165 degrees and the cheese is melted and bubbly.

    Heat oil or butter in a skillet over medium heat. Add onions and garlic and allow to caramelize. Season chicken with thyme, salt and pepper. Push onions to side and cook chicken thoroughly and until temperature reaches 155 F degrees.
