Step-by-Step Instructions

Prepare the Chicken:

Slice each chicken breast into thin cutlets so they cook evenly and coat both sides with olive oil. Mix the seasoned salt onion powder garlic powder and black pepper in a bowl and generously rub onto all sides of the chicken. This early seasoning infuses the meat with flavor from the inside out.

Sear the Chicken:

In a large skillet pour in one tablespoon of olive oil and set over medium high heat. Sear the seasoned cutlets for about four to five minutes per side until they turn golden and the centers read 165 degrees on a thermometer. Taking the time to brown both sides builds delicious fond at the bottom of the pan. Set the chicken aside so you can build your gravy.

Caramelize the Onions:

Lower the heat to medium low and add the rest of the olive oil with the butter to the same pan. Toss in all sliced onions and stir so every piece is coated with fat. Let them cook slowly for twenty five to thirty minutes stirring occasionally as the onions collapse and take on deep golden color. The patience here pays off as the slow caramelization brings out all the natural onion sweetness.

Make the Gravy:

When onions are caramelized sprinkle flour over and stir until every strand is coated. Let it cook for two to three minutes which cooks off the raw flour taste and gets you that roux base. Gradually whisk in beef broth along with Worcestershire and onion soup mix. Let the sauce simmer until thick and silky.

Finish and Serve:

Return the cooked chicken cutlets to the skillet nestling them into the sauce. Sprinkle mozzarella over the top of each piece so it melts into the gravy. Cover and let stand over low heat just until the cheese is gooey and irresistible. Spoon extra gravy over for serving.

Save

Honestly I never get tired of the sweet aroma of onions while they caramelize. My daughter always comes running into the kitchen whenever I start this dish and asks to help sprinkle the cheese. It has become our little tradition.

Storage Tips

Store leftovers in an airtight container in the fridge. This chicken will keep well for up to four days and reheats beautifully either in the microwave or gently in a skillet. The flavors deepen after a day which makes this a great make ahead option.

Ingredient Substitutions

If you crave a classic French onion taste swap mozzarella for provolone or Gruyere These both melt beautifully and bring a nutty oomph to the dish You can use chicken thighs instead of breasts for extra succulence I sometimes do this when I want even more richness Swapping in gluten free flour works well if you need a gluten free option

Serving Suggestions

Serve over fluffy mashed potatoes rice or even crusty bread so you can soak up every bit of gravy. I often add a side of green beans or a simple arugula salad with lemon for contrast.
