Ingredients You’ll Need

This French Onion Chicken & Rice recipe relies on just a handful of accessible ingredients, each bringing something special—aroma, creaminess, crunch, or color. Every piece plays its part, so don’t skip out on the details for maximum deliciousness!

• Butter: Adds richness and helps caramelize the onions to sweet, golden perfection.
• Extra virgin olive oil: A touch of oil prevents the butter from burning and deepens the sauce.
• Sweet onions: The heart of the dish—thick, slow-cooked slices turn deep gold and taste sweet and savory.
• Fresh garlic, minced: A punch of fragrance and flavor that makes every bite pop.
• Kosher salt: Essential for bringing out all the savory notes and balancing the richness.
• Freshly ground black pepper: Adds just enough gentle heat.
• Dry tarragon: Brings a subtle anise note that tastes beautifully French.
• Dry thyme: Classic French herb flavor that belongs in every onion-centric dish.
• Brandy or white wine: This splash deepens flavor and adds a sophisticated aroma.
• Worcestershire sauce: A secret umami booster!
• Button mushrooms: Lightly browned for earthy savoriness and toothsome texture.
• White uncooked rice: The cozy base that soaks up all those luxurious juices.
• Baby spinach: Wilts down to add color and freshness that cuts through the richness.
• Chicken stock: Makes everything extra savory and cohesive—choose homemade if you can.
• Heavy cream: Lends lovely body for that irresistible, spoonable sauce.
• Cooked chicken, torn into bite-sized pieces: Use rotisserie or home-cooked for super juicy, flavorful bites.
• Gruyere Swiss cheese, shredded: The signature topping that gets gorgeously melty, golden, and bubbly.

How to Make French Onion Chicken & Rice

Step 1: Caramelize the Onions

This is the foundation for the big, bold flavor that French Onion Chicken & Rice is known for. Melt two tablespoons of butter with two tablespoons of oil in a large, high-sided skillet over medium-low heat. Add your thickly sliced onions, spreading them in an even layer. Be patient and let them cook undisturbed for 15 minutes. Then, stir and cook another 15 minutes, continuing to check and cook for 10-15 minutes more until deeply caramelized. Don’t rush—this step is worth every minute!

Step 2: Build the Herb-Infused Onion Base

Once the onions are deeply golden and jammy, turn the heat to medium and stir in the minced garlic. Let it sizzle for about a minute, then sprinkle in salt, pepper, tarragon, and thyme. The pan will smell heavenly! Cook for another minute, then carefully add the brandy or white wine (off the heat to be safe). Return to the heat and simmer until the liquid evaporates (around five minutes). Stir in Worcestershire sauce, then set the onions aside—they’re like edible gold.

Step 3: Brown the Mushrooms and Toast the Rice

In a separate large saucepan or medium pot over medium-high heat, add the mushrooms dry (no oil or butter yet) to encourage browning. Let them sit, undisturbed, until they’re deep golden and reduced—about 5-10 minutes. Add the remaining butter and oil, letting them melt, then add the white rice. Sauté for about five minutes until the rice starts to turn a touch golden and smells nutty. This step yields incredible flavor in the final dish.

Step 4: Add Spinach and Simmer

Next, toss in the baby spinach and stir it through just until wilted—usually one minute. Pour in the chicken stock, bring the pot to a gentle simmer, then lower the heat to low. Cover and cook for 15 minutes, letting the rice absorb the liquid and flavors. Your kitchen will smell irresistible at this point!

Step 5: Finish the Filling with Cream and Chicken

Remove the lid and stir in the heavy cream—this transforms the base into a deliciously rich and creamy risotto-like mixture. Add in the bite-sized pieces of cooked chicken, stirring until everything is just heated through and perfectly combined.

Step 6: Layer, Cheese, and Broil

Preheat your broiler. Lightly coat a 9x13x3-inch casserole dish with kitchen spray and pour in the creamy rice mixture. Spoon the caramelized onions over the top, then generously scatter the shredded Gruyere all over. Broil for a minute or two until the cheese is bronzed, bubbling, and absolutely glorious—stay close by so it doesn’t go from golden to scorched!

Step 7: Serve Immediately and Savor

Once the topping is perfectly melted and slightly browned, scoop up generous portions of French Onion Chicken & Rice and enjoy every creamy, cheesy, French onion-filled bite. It’s comfort food at its absolute best!

How to Serve French Onion Chicken & Rice

Garnishes

For a little extra flair, sprinkle the top with fresh thyme leaves or snipped chives just before serving. They add pops of color and a refreshing herbal note that compliments the deep, savory flavors of French Onion Chicken & Rice. For a hint of crunch, try adding a few homemade sourdough croutons on top—the way you’d find in classic French onion soup!

Side Dishes

Since French Onion Chicken & Rice is rich and hearty, I love offering something light on the side. Think: a crisp green salad dressed with zippy vinaigrette, roasted green beans, or simple steamed broccolini. A bright, tangy side brings balance and freshness to your plate, inviting you back for another bite.

Creative Ways to Present

If you’re serving this for company, spoon French Onion Chicken & Rice into individual oven-safe ramekins, then broil with Gruyere for mini, bubbling gratin-style portions. Or, for a casual family-style meal, bring the whole casserole to the table and encourage everyone to dig in. For a restaurant-worthy twist, top each portion with extra caramelized onions and a delicate tuft of microgreens.

Make Ahead and Storage

Storing Leftovers

Leftover French Onion Chicken & Rice stores beautifully in an airtight container in the refrigerator for up to four days. The flavors even deepen and get richer as they mingle, making leftovers a lunchtime treat that’s genuinely exciting.

Freezing

You can freeze portions of this casserole, tightly wrapped, for up to two months. To keep the texture best, freeze before broiling with cheese, then add fresh Gruyere and broil after reheating. Let it thaw in the fridge overnight before reheating for the smoothest results.

Reheating

To reheat, place portions in a microwave-safe dish and cover loosely to trap moisture; heat on medium power until hot. For crispier, cheesy tops, you can reheat leftovers in the oven at 350°F, covered with foil, for about 20 minutes, then remove foil and broil for a minute or two to re-melt the cheese.

FAQs

Can I use brown rice instead of white?

Yes! Brown rice adds a nutty flavor and extra nutrients, but will require a longer cook time and possibly a bit more liquid. Start checking for doneness after 35 minutes and add extra stock as needed.

What other cheeses work if I can’t find Gruyere?

Gruyere is classic, but Swiss, Jarlsberg, or even sharp provolone melt well and bring that signature nutty flavor. In a pinch, a mixture of mozzarella and Parmesan also works for a beautifully melty topping.

Is there a vegetarian version of French Onion Chicken & Rice?

Absolutely! Swap the chicken for cooked chickpeas, extra mushrooms, or even roasted cauliflower, and substitute vegetable stock for chicken stock. You’ll still get loads of savory, herby, cheesy goodness.

What’s the best way to caramelize onions without burning them?

Patience, low heat, and occasional stirring are your best friends! Make sure to use enough butter and oil, let the onions cook undisturbed at first, and keep an eye on them after the initial 30 minutes so they don’t catch or scorch. A splash of water or stock can help deglaze the pan if needed.

Can I prep this dish ahead for entertaining?

Definitely. You can fully assemble the casserole up to the step before broiling, cover, and refrigerate it up to 24 hours in advance. When you’re ready to serve, bring it to room temperature and then broil with cheese just before eating for the freshest, meltiest results.
