Ingredients

Chicken breasts: choose boneless and skinless for quicker cooking and easier eating
Yellow onions: the star of the dish, they caramelize beautifully to create that sweet deep flavor; pick firm onions with dry skins
Butter: for cooking the onions and adding richness
Olive oil: helps prevent the butter from burning while cooking
Garlic: adds aromatic depth, fresh cloves work best
Beef broth: gives the sauce a savory backbone; low sodium allows you to control salt levels
Thyme: fresh if possible for brightness, dried works if not
Salt and pepper: season to taste
Flour: a small amount to thicken the sauce; use all-purpose for best results

 

 

Step-by-Step Instructions

Sauté the onions:
Cook sliced onions over medium low heat in a mix of butter and olive oil for about 25 minutes stirring often until deeply caramelized and soft. Patience here turns simple onions into a flavor powerhouse.
Prepare the chicken:
While the onions cook, season chicken breasts generously with salt and pepper. Heat a separate pan and sear chicken on both sides over medium high heat until golden brown but not fully cooked through, about 3-4 minutes per side.
Make the sauce:
Sprinkle flour over the caramelized onions and cook for 1-2 minutes to remove the raw taste. Slowly whisk in beef broth ensuring no lumps form. Add thyme and simmer until the sauce thickens slightly, about 5 minutes.
Combine and finish cooking:
Return the chicken to the pan with the onion sauce. Spoon sauce over the chicken and continue to cook on low heat for another 8-10 minutes until the chicken is fully cooked and juicy. Adjust seasoning with salt and pepper as needed.

French onion flavor comes from the long caramelization of onions which transforms their flavor

 

My favorite ingredient here is the slow caramelized onions. I remember the first time I waited nearly half an hour for the onions to darken and how that little extra time made every bite rich and indulgent. It’s a small step that pays off in a big way.

 

 

Storage Tips

Store any leftovers in an airtight container in the refrigerator for up to three days. Reheat gently on the stove or in the microwave to keep the chicken tender and the sauce intact. This dish does not freeze well because the sauce can separate.

 

Ingredient Substitutions

Chicken thighs can be used instead of breasts for a juicier result but will take slightly longer to cook thoroughly

Vegetable broth works fine if you want a lighter sauce or prefer a vegetarian option with tofu instead of chicken

Using shallots instead of yellow onions will create a milder, sweeter flavor that is just as delicious

 

 

Serving Suggestions

Serve over egg noodles, mashed potatoes, or creamy polenta to soak up the rich onion sauce

Add a simple green salad or roasted vegetables on the side for a balanced meal

A crusty baguette is perfect for sopping up leftover sauce

 

 

Pro Tips

Do not rush caramelizing the onions or the flavor will be thin. Low and slow is the key here
Adding flour directly to the onions helps create a silky sauce without lumps, so be sure it cooks through slightly before adding broth
Rest your chicken a couple of minutes after cooking to lock in juices and keep it tender
