Storage and Reheating TipsStore any leftover French Onion Chicken in an airtight container in the refrigerator for up to 3 days. To reheat, simply place it in the microwave for 1-2 minutes or in the oven at 350°F for about 10 minutes, until warmed through.

Cooking Tips

• Caramelize the Onions: If you have a bit of extra time, you can sauté the onions in a skillet before adding them to the slow cooker. This will enhance their sweetness and depth of flavor, making the dish even more delicious.
• Customize the Cheese: While Swiss cheese is traditional, feel free to experiment with other cheeses like Gruyère, provolone, or even mozzarella for a slightly different flavor profile.
• Season Generously: The key to building great flavor in this dish is seasoning the chicken well before cooking. Don’t be shy with the salt, pepper, thyme, and parsley—they all contribute to the final flavor.
• Don’t Overcook the Chicken: Keep an eye on your slow cooker, as every model is different. You want the chicken to be cooked through and tender but not overcooked, which can dry it out.

Optional Variations

• Mushroom Addition: Add some sliced mushrooms to the slow cooker for an earthy, umami twist on the classic French onion flavors.
• Thyme Lovers: If you love the flavor of thyme, feel free to add an extra ½ teaspoon of dried thyme or a few sprigs of fresh thyme for even more herbaceous goodness.
• Garlicky Version: If you’re a garlic fan, add 1-2 cloves of minced garlic to the slow cooker with the onions for a more pronounced garlic flavor.

Slow Cooker French Onion Chicken Recipe

Ingredients:

• 2 pounds boneless, skinless chicken breasts (or chicken thighs)
• Salt and pepper, to taste
• ½ teaspoon dried thyme
• 1 teaspoon dried parsley
• 1 ounce Lipton onion soup & dip mix (1 envelope)
• 3 yellow onions, very finely sliced
• 1 can condensed French onion soup (10.5 ounces)
• 5-6 thick slices of Swiss cheese
