French Onion Soup Chicken Made Right Way

First step: caramelize the onions.

Under medium-low heat, melt butter in a large skillet. Add sliced onions and season with salt and pepper. Cook until the onions are deep golden brown, 20 to 25 minutes, stirring repeatedly.

Second step: add flavor.

Add minced garlic, thyme, Worcestershire sauce, and balsamic vinegar if you use them. To intensify the flavors, cook for two more minutes.

Third step: create the broth.

Whisk broths and cornstarch in a small bowl. Pour into the skillet with the onions; simmer for five minutes until slightly thickening. Take onions from the skillet and put aside.

Second step: sear the chicken.

In the same skillet, set the olive oil on medium heat. Salt and pepper season chicken breasts; then saute for 4 to 5 minutes on each side until golden brown.

Step 5: Top and Simmer with Onions

Spoon the caramelized onions back onto the skillet over the chicken. Let the tastes fuse.

Step 6: Melt the Cheese.

Over every chicken breast, sprinkle Gruyère and mozzarella. Cook covered until the cheese melts and bubbles, five more minutes.

Third step: garnish and serve.

For dipping, sprinkle fresh parsley and present hot with toasted French bread.

Useful Advice for Creating the Recipe

Be patient when caramelizing is low; slow cooking helps the onions taste sweet naturally.
Gruyère melts wonderfully and has the ideal nutty taste for authenticity.

Techniques of Serving

The perfect side for soaking up the great broth is mashed potatoes.
Steamed vegetables will lighten it; use roasted asparagus or green beans.
