Ingredients You’ll Need

Every ingredient in French Onion Chicken & Rice is hand-picked for balance: sweetness and depth from caramelized onions, savory chicken, earthy mushrooms, lush cream, and a final crown of Gruyere. Together, they create irresistible comfort you won’t want to miss.

• Sweet onions: The start of any great French onion recipe—cook them low and slow for irresistible caramelized flavor.
• Unsalted butter & olive oil: For rich flavor and to help those onions brown beautifully without burning.
• Garlic: Adds aromatic warmth and savory backbone.
• Kosher salt & freshly ground black pepper: Just the thing for bringing all the savory flavors forward.
• Dried tarragon & thyme: A fragrant duo that gives the dish a French countryside vibe.
• Brandy or white wine: A splash adds subtle complexity and brings out the sweetness in the onions—choose whichever you have!
• Worcestershire sauce: For background umami and a touch of tang.
• Button mushrooms: Earthy, meaty mushrooms soak up the flavors and offer a satisfying bite.
• White uncooked rice: The sturdy foundation—fluffy, tender, and perfect for soaking up all the flavor.
• Baby spinach: Adds a flash of green and keeps things feeling bright and fresh.
• Chicken stock: The liquid gold that cooks the rice and deepens all the savory notes in the dish.
• Heavy cream: Makes the casserole creamy and luxurious without being too heavy.
• Cooked chicken (torn into pieces): Rotisserie chicken is speedy and soaks up all the flavor—leftover roasted or poached chicken works too.
• Gruyere Swiss cheese: An absolute must for that signature French onion golden-bubbly top.

Variations

The beauty of French Onion Chicken & Rice is how easy it is to tweak to fit your mood or dietary preferences. Whether you want to add more veggies, go lighter, or make it vegetarian, there’s a delicious way to make this recipe your own!

• Vegetarian Option: Swap the chicken with extra mushrooms, white beans, or chickpeas, and use vegetable broth for the same cozy vibes with no meat.
• Low-Carb Version: Replace rice with cauliflower rice—just shorten the cooking time and use a bit less stock for a lighter, grain-free twist.
• Cheese Swap: If Gruyere isn’t your favorite, try Swiss, provolone, or even a blend of mozzarella and parmesan (just make sure you use a melt-friendly cheese for maximum bubbly goodness).
• Add Veggies: Toss in sautéed zucchini, roasted red peppers, or baby kale for even more texture and nutrition.

How to Make French Onion Chicken & Rice

Step 1: Caramelize the Onions

Start by melting two tablespoons of the butter and two tablespoons of the oil in a large skillet over medium-low heat. Add your halved and thickly sliced onions and simply let them relax without stirring for 15 minutes—this is where the magic begins! Stir once, then cook another 15 minutes, letting the edges darken and soften deeply. If you adore extra-caramelized onions (like me!), cook for another 10-15 minutes, stirring occasionally, until sweet and golden brown all over. The patience is absolutely worth it.

Step 2: Build Layers of Flavor

Once your onions are soft and deeply golden, turn the heat to medium and add minced garlic. Let it sizzle and work its aromatic magic for 1 minute. Sprinkle in the salt, pepper, tarragon, and thyme, stirring well so every onion strand is coated in herby goodness. Off the heat, carefully add the brandy or white wine—this step will deglaze all the flavorful brown bits! Let it cook until the liquid evaporates (about 5 minutes), then stir in Worcestershire sauce, remove from heat, and set the pan aside.

Step 3: Cook Mushrooms and Rice

In a large saucepan or medium pot over medium-high heat, toss in just the mushrooms—no oil yet! Let them sear dry until golden and their moisture evaporates, about 5-10 minutes. Add the remaining butter and oil, then stir in the rice. Cook for 5 minutes, letting the rice absorb flavor and toast lightly. Add the spinach, cooking until just wilted for a pop of green.

Step 4: Simmer, Mix, and Assemble

Pour the chicken stock into the pan with the rice and bring it all to a simmer. Reduce the heat to low, cover, and let it cook for 15 minutes. Once the rice is done, stir in the heavy cream and juicy bites of cooked chicken. Cook gently until just heated through—don’t let it boil or the cream can separate.

Step 5: Layer and Broil to Perfection

Arrange your rice-chicken mixture into a buttered 9×13-inch casserole dish. Scatter that glorious pile of caramelized onions over the top, then finish with a thick layer of shredded Gruyere. Broil just until the cheese melts, bubbles, and browns—about 2-3 minutes. Serve French Onion Chicken & Rice while it’s still gloriously hot and gooey.

Garnishes

Finish French Onion Chicken & Rice with a flourish—sprinkle with extra fresh thyme leaves, chopped parsley for freshness, or a scattering of more Gruyere right out of the broiler. If you really want to evoke French onion soup, pop a few crispy croutons on top!

Side Dishes

This casserole is a meal on its own, but it shines even brighter with a crisp green salad tossed in light vinaigrette, oven-roasted asparagus, or simple steamed green beans. For true comfort, serve with warm, crusty baguette—perfect for scooping up every cheesy scrap.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Let your casserole cool to room temperature, then cover well or transfer to airtight containers. French Onion Chicken & Rice will keep beautifully in the fridge for up to 3-4 days—just long enough to savor leftovers for lunch or dinner!

Freezing

For longer storage, this dish freezes surprisingly well. Once cooled, wrap tightly (or use a lidded dish), label, and freeze for up to 2 months. Thaw overnight in the fridge before reheating, and know that the texture may be a touch softer after freezing, but the flavor is still sublime.

Reheating

Reheat gently in the oven at 350°F (175°C), covered, until hot throughout—about 20-30 minutes. Or, microwave individual servings, adding a splash of extra cream or chicken stock if needed to restore that delectable creaminess. Add a fresh sprinkle of cheese and broil for a quick cheese-melt refresh!
