Ingredients

- 3 tablespoons butter, divided
- 3 tablespoons extra virgin olive oil, divided
- 3 pounds sweet onion (about 4 large), thickly sliced
- 1 tablespoon fresh garlic, minced
- 1 1/2 teaspoons kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1 teaspoon dried tarragon
- 1 teaspoon dried thyme
- 1 tablespoon Worcestershire sauce
- 8 ounces button mushrooms, sliced
- 1 1/2 cups uncooked white rice
- 2 cups baby spinach, packed (about 2–3 ounces)
- 3 cups chicken stock
- 1 cup heavy cream
- 3–4 cups cooked chicken, torn into bite-sized pieces
- 4 ounces Gruyère cheese, shredded
Step-by-Step Directions
- Melt the Butter and Oil
- In a large nonstick skillet, melt 2 tablespoons of butter with 2 tablespoons of olive oil over medium-low heat. This combination will help achieve a beautiful golden color on your onions while adding rich flavor.
- Caramelize the Onions
- Add the thickly sliced onions to the pan, cooking them undisturbed for 15 minutes. After that, stir the onions and continue cooking for another 15 minutes or until they are deeply caramelized and gloriously golden. This step is crucial as it develops the base flavor for your dish.
- Add Aromatics
- Lower the heat to medium, then add in the minced garlic, kosher salt, freshly ground black pepper, tarragon, and thyme. Sauté everything together for one minute, allowing the wonderful aromas to meld. Pour in the Worcestershire sauce and set this delicious mixture aside.
- Prepare the Mushrooms
- In a medium saucepan, dry-cook the sliced mushrooms for about 5 to 10 minutes until they are browned. The mushrooms will add an earthy richness to the dish, complementing the sweetness of the onions beautifully.
- Toast the Rice
- Stir in the remaining butter and olive oil, allowing it to melt. Then add the uncooked rice to the saucepan, lightly toasting it for 5 minutes until it becomes fragrant. This step enhances the flavor of the rice.
- Incorporate Spinach
- Add in the baby spinach and cook just until it wilts, which should take about one minute. This extra layer of greens adds nutrition and color to your dish.
- Cook the Rice
- Pour in the chicken stock, bring the mixture to a boil, cover, and reduce it to a simmer for 15 minutes. This is when the rice absorbs all the savory flavors you’ve created.
- Combine Ingredients
- Once cooked, remove the lid and stir in the heavy cream and the torn cooked chicken. Heat everything through to ensure it’s piping hot and well combined.
- Prepare for Baking
- Grease a 9×13×3-inch baking dish and pour in the delicious rice and chicken mixture. Top it generously with the caramelized onions and sprinkle shredded Gruyère cheese on top.
- Broil the Dish
- Broil the dish until the cheese is molten and golden, creating that irresistible gooey topping that everyone loves. Serve immediately for best results!
Tips & Tricks
Here are some chef’s secrets to elevate your French Onion Chicken & Rice:
- Choose the Right Onions: Sweet onions caramelize beautifully and enhance the dish’s sweetness, but feel free to mix in a few yellow onions for a deeper flavor.

- Use Leftover Chicken: This dish is an excellent way to use up leftover chicken from previous meals, making it even quicker to prepare.
- Experiment with Cheese: While Gruyère is a classic choice, feel free to mix in other cheeses like mozzarella or cheddar for a unique twist.
