Step‑by‑Step Instructions for French Onion Chicken & Rice
Step 1: Caramelize Onions
In a large skillet over medium-low heat, melt the butter and olive oil together. Add the sliced sweet onions, stirring occasionally, and cook for about 30 to 45 minutes until they become deeply caramelized and a rich golden-brown color. Patience is key, so enjoy the aroma as the onions turn sweet and tender.
Step 2: Add Aromatics
Once the onions are caramelized, stir in the minced garlic, kosher salt, black pepper, dried tarragon, and dried thyme. Cook this aromatic mixture for an additional minute until fragrant, then deglaze the pan by pouring in the brandy or white wine. Continue cooking until the liquid has mostly evaporated, intensifying the flavor before setting the mixture aside.
Step 3: Prepare Rice Mixture
In a separate pot, start by sautéing the sliced button mushrooms over medium heat until tender. Then, add the remaining olive oil and butter. Stir in the uncooked white rice for about 5 minutes, allowing it to absorb those flavorful juices. Next, mix in the baby spinach and cook until just wilted, which adds a lovely color before pouring in the chicken stock. Cover and simmer for about 15 minutes until the rice is tender.
Step 4: Combine Ingredients
Once the rice is cooked, remove it from heat and stir in the heavy cream and cooked chicken pieces, ensuring everything is well-used and flavorful. Transfer the mixture to a greased 9×13-inch casserole dish, spreading it evenly. Layer the caramelized onion mixture on top, followed by a generous sprinkle of shredded Gruyère cheese, which will create a delicious golden topping.
Step 5: Broil
Preheat your oven’s broiler. Place the casserole under the broiler for about 3-5 minutes, keeping a close eye on it. Broil until the cheese is melted, bubbly, and beautifully golden. This final step enhances the flavors of your French Onion Chicken & Rice casserole, inviting everyone to the table for a comforting meal.
How to Store and Freeze French Onion Chicken & Rice
Fridge: Store leftovers in an airtight container for up to 3 days. Make sure it’s completely cooled before sealing to prevent moisture buildup.
Freezer: For longer storage, freeze the casserole in a tightly sealed container for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: Reheat individual portions in the microwave, adding a splash of broth for creaminess, or bake in the oven at 350°F until warmed through.
Leftovers Tip: Be mindful that rice absorbs moisture over time, so add a bit of broth when reheating to keep your French onion chicken & rice casserole deliciously creamy.

French Onion Chicken & Rice Casserole Recipe FAQs
How do I know if my onions are ripe for caramelizing?
Absolutely! Look for sweet onions that feel firm with no dark spots or soft areas. You want them to be fresh, as this will provide the best sweetness when caramelized. If sweet onions aren’t available, yellow onions can work just as well!
What’s the best way to store leftovers of the casserole?
Very! Store any leftovers in an airtight container in the fridge for up to 3 days. Make sure it has cooled completely before sealing to prevent moisture buildup, which can alter the texture when reheating.
Can I freeze the French Onion Chicken & Rice Casserole?
The more the merrier! You can freeze the casserole in a tightly sealed container for up to 3 months. For best results, thaw it overnight in the fridge before reheating. If you forgot to defrost it, cook it directly from frozen but extend the baking time.
What should I do if the rice absorbs too much liquid during storage?
No worries! When reheating, simply add a splash of broth or cream to the casserole. This will help bring back that delightful creaminess and ensure the rice stays tender, creating a deliciously comforting meal again.
Are there any dietary considerations I should keep in mind?
Absolutely! If you have a dairy allergy, you can substitute butter and cream with olive oil and dairy-free milk, respectively. Additionally, it’s important to check that the Worcestershire sauce is gluten-free if gluten is a concern, as some brands contain gluten.
How can I enhance the flavors after making this dish?
Certainly! Consider adding a sprinkle of fresh herbs like parsley or thyme right before serving for a burst of freshness. You can also experiment with cheese varieties; using a smoked gouda or sharp cheddar can give it an exciting twist if you want to change things up!
