Ingredients

For the Chicken

  • 6 medium chicken thighs (skin-on, bone in)
  • Salt and pepper
  • 1 tsp onion powder
  • 2 tbsp butter

For the Onions

  • 1 large onion (thinly sliced)
  • 1/2 cup dry white apple vinegar or chicken broth
  • 1 tsp fresh thyme leaves

For Topping

  • 8 ounces Gruyere cheese (shredded)

For Garnish

  • 2 tablespoons fresh parsley, finely chopped

How to Make French Onion Chicken Recipe

Step 1: Pat Dry the Chicken

Pat the chicken very dry using paper towels. Sprinkle both sides generously with salt, pepper, and onion powder.

Step 2: Sear the Chicken

Add the butter to a large oven-proof skillet over medium heat. Once melted and hot:
1. Place the chicken skin side down in the skillet.
2. Cook for 4 to 5 minutes until golden brown.
3. Flip over and cook an additional 4 minutes.
4. Transfer cooked chicken to a plate.

Step 3: Caramelize Onions

In the same skillet:
1. Add the sliced onions and sprinkle with a little more salt and pepper.
2. Reduce heat to medium-low.
3. Caramelize onions slowly until golden brown, stirring frequently—this may take up to 20 minutes.

Step 4: Preheat Oven

During the last 10 minutes of caramelizing onions, preheat your oven to 375ºF.

Step 5: Add Thyme and Vinegar

Once onions are caramelized:
1. Add thyme to the pan; cook for an additional minute until fragrant.
2. Pour in apple vinegar or broth and bring to a simmer.
3. Cook until liquid is reduced by half (about 2 minutes).

Step 6: Combine and Bake

Nestle the seared chicken back into the pan:
1. Sprinkle grated Gruyere cheese on top of each piece of chicken.
2. Bake in preheated oven for about 20 minutes until cheese is melted and bubbly.

How to Perfect French Onion Chicken Recipe

  • Quality Cheese Matters: Use high-quality Gruyere cheese for superior melting and flavor.
  • Adjust Seasoning: Taste as you go; seasoning can be adjusted based on personal preference.
  • Let It Rest: Allow the chicken to rest after baking for juiciness before serving.

Best Side Dishes for French Onion Chicken Recipe

The right side dishes can complement your French Onion Chicken perfectly. Here are some great options to consider:

  1. Roasted Vegetables: A mix of seasonal vegetables roasted until tender adds color and nutrients.
  2. Mashed Potatoes: Creamy mashed potatoes provide comfort and soak up the delicious sauce from the chicken.
  3. Cauliflower Rice: A low-carb option that pairs well while keeping your meal light and healthy.
  4. Steamed Asparagus: Lightly steamed asparagus offers a fresh crunch that contrasts beautifully with rich chicken flavors.

Common Mistakes to Avoid

Avoiding common mistakes can elevate your French Onion Chicken recipe from good to great. Here are some pitfalls to watch out for:

  • Skipping the Drying Step: Failing to pat the chicken dry can prevent it from achieving that perfect golden crust. Always dry your chicken thoroughly before seasoning.
  • Not Caramelizing the Onions Properly: Rushing the onion caramelization process will lead to a bitter flavor. Take your time and allow them to cook low and slow for about 20 minutes until golden.
  • Using the Wrong Type of Cheese: Gruyere cheese adds unique flavor and texture to this dish. Substituting with a different cheese may not yield the same results.
  • Overcrowding the Pan: Placing too many chicken thighs in the pan at once can cause steaming instead of searing. Cook in batches if necessary to ensure even cooking.
  • Ignoring Internal Temperature: Not checking the chicken’s internal temperature can lead to undercooked meat. Always ensure it reaches 165°F for safe consumption.

Refrigerator Storage

  • Store leftover French Onion Chicken in an airtight container.
