How to Make French Onion Chicken
-
Preheat the oven to 350°F. This step is vital to ensure your chicken cooks evenly and stays tender.
-
Season the chicken with olive oil, sea salt, and fresh cracked pepper. Sear in a Dutch oven for 2 minutes per side (thighs) or 3 minutes per side (breasts), then set aside. This browning adds amazing flavor!
-
Add the onions and shallots to the same pan. Cook for about 15 minutes, stirring regularly, until they are golden and caramelized. This low and slow approach is key to unlocking deep, sweet flavors.
-
Stir in garlic and butter, cooking for an additional 5 minutes until fragrant. The aroma will be irresistible!
-
Deglaze the pan with white wine, letting it reduce by two-thirds, about 3 minutes. This step lifts all the delicious bits from the pan, adding flavor to your sauce.
-
Stir in beef stock, Worcestershire sauce, and bouillon paste; let simmer for 5 minutes. This will create a robust sauce that complements the chicken beautifully.
-
Return the chicken to the pan, spoon sauce over the top, cover, and bake for 20 minutes. This allows the flavors to meld and the chicken to soak in the deliciousness.
-
Top with Gruyère cheese, cover, and let it melt before serving. You’ll love that gooey, cheesy finish!
-
For the Mashed Potatoes: Boil golden potatoes for 20 minutes, then mash with milk, butter, and your favorite seasonings until creamy and fluffy.
Optional: Serve with a sprinkle of fresh parsley for a pop of color.
