Step-by-step overview

Creating this delicious casserole is straightforward and doesn’t require any culinary school skills. To prepare it, you’ll need to sauté some onions, mix a few key ingredients, and pop it into the oven. In just a little over an hour, you’ll have a bubbling, cheesy dish ready to serve.

What you’ll need

Gather these items to whip up this delightful casserole:

• 2 cups cooked, shredded chicken
• 1 cup uncooked long grain white rice
• 1 (10.5 oz) can French onion soup
• 1 (10.5 oz) can cream of chicken soup
• 1 1/2 cups shredded Swiss or mozzarella cheese
• 1/2 cup milk
• 1 tablespoon butter
• 1 small onion, thinly sliced
• Salt and black pepper to taste
• Fresh thyme or parsley for garnish (optional)

Feel free to swap out the cheese; cheddar works beautifully if you’re looking for a sharper flavor.

How to prepare it

Now, let’s get into the nitty-gritty of making this casserole.

1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. In a skillet, melt the butter over medium heat. Add the sliced onions and sauté until they are caramelized—about 10–12 minutes. Set them aside.
3. In a large bowl, combine the uncooked rice, French onion soup, cream of chicken soup, milk, salt, and pepper.
4. Stir in the cooked chicken and half of the shredded cheese until well mixed.
5. Pour the mixture into the prepared baking dish, spreading it out evenly.
6. Top it off with the caramelized onions and the remaining cheese.
7. Cover with foil and bake for 45 minutes. After that, remove the foil and bake for an additional 10–15 minutes until the cheese is melted and bubbly, and the rice is tender.
8. Garnish with thyme or parsley before serving, if desired.

Best ways to enjoy it

Serving this casserole is all about presentation and flavor pairing. You can serve it directly from the baking dish for a rustic feel. To make it even more appealing, add a sprinkle of fresh herbs on top for a pop of color. Pair with a light green salad or steamed vegetables, and perhaps some crusty bread for a complete meal. A glass of white wine would also complement the flavors beautifully.

Storage and reheating tips

Leftovers can be the best part of making a casserole! Store any uneaten portions in an airtight container in the refrigerator for up to three days. When reheating, make sure to cover it with foil to keep moisture in, and heat it in the oven at 350°F (175°C) until warmed through. You can also freeze it for up to three months. Just remember to allow it to cool completely before freezing, and reheat from frozen, adjusting the cooking time as needed.

Helpful cooking tips

Here are a few tips to elevate your casserole:

• Sauté the onions until they’re deeply caramelized for a more robust flavor.
• Use rotisserie chicken for added convenience—just shred it and mix it in!
• If you want an extra cheesy topping, sprinkle more cheese on top during the last 10 minutes of baking.

Creative twists

Feel free to experiment a bit! Try using different types of cheese, add sautéed mushrooms for an umami boost, or mix in some cooked vegetables like broccoli or spinach. You can also swap the long grain rice for a wild rice blend for a nuttier flavor. Spicy mustard or a touch of Worcestershire sauce can add a nice zing too!

How long does it take to make this casserole?

It takes about 20 minutes to prep, plus 55–60 minutes in the oven.

Can I use leftover turkey instead of chicken?

Is there a gluten-free version available?

Always ensure the casserole is heated to an internal temperature of 165°F (74°C) when reheating.
