How to Make Chicken with French Onion
Step 1: Caramelize the Onions
-
In a large skillet, heat 2 tbsp butter and 2 tbsp olive oil over medium heat.
-
Add the sliced onions, salt, sugar, and thyme.
-
Cook, stirring frequently, for 20–25 minutes, until golden and deeply caramelized.
-
Stir in garlic during the last 2 minutes.
-
Deglaze pan with white wine (if using) or a splash of broth — scraping up browned bits.
Low and slow is the key here — don’t rush the onions!
Step 2: Cook the Chicken
-
While the onions cook, season chicken with salt, pepper, and garlic powder.
-
In a separate skillet (or the same pan, once onions are removed), heat 1 tbsp butter + 1 tbsp olive oil.
-
Sear chicken for 4–5 minutes per side, until golden brown and almost cooked through.
-
Remove from heat and set aside.
Chicken will finish cooking in the oven under the cheese topping.
Step 3: Make the Sauce
-
Once onions are caramelized and deglazed, add ¾ cup broth and 1 tsp Dijon mustard (optional).
-
Stir and simmer for 2–3 minutes.
-
Return the seared chicken to the skillet, nestling into the onions and sauce.
Step 4: Add Cheese & Broil
-
Sprinkle each chicken piece with Gruyère, mozzarella, or Swiss cheese.
-
Preheat broiler on high.
-
Place skillet under broiler for 3–5 minutes, or until cheese is melted, bubbly, and golden.
Keep a close eye under the broiler — it can go from golden to burnt quickly!
Step 5: Garnish & Serve
-
Garnish with fresh thyme or chopped parsley.
-
Spoon extra onion sauce over each piece when serving.
