Ingredients You’ll Need
To make this French Onion Chicken Rice Casserole, you will need:
- 2 cups cooked chicken, shredded
- 1 cup cooked rice
- 1 large onion, sliced
- 2 cloves garlic, minced
- 1 cup French onion dip
- 1 tsp dried thyme
- Salt and pepper to taste
- 1 cup shredded cheese (Swiss or Gruyère)
These ingredients are simple and versatile, and you can easily swap chicken for turkey or use brown rice for a healthier version.
Step-by-Step Instructions
Step 1 – Prepare the Onions and Garlic
Preheat your oven to 350°F (175°C). In a skillet over medium heat, sauté the sliced onions and minced garlic until they are golden brown and fragrant. This caramelization brings out the sweetness in the onions and enhances the flavor of the casserole.
Step 2 – Mix the Chicken and Rice
In a large mixing bowl, combine the shredded chicken, cooked rice, sautéed onions and garlic, French onion dip, dried thyme, salt, and pepper. Stir until everything is evenly coated and mixed together.
Step 3 – Assemble the Casserole
Transfer the mixture to a greased baking dish. Smooth it out evenly with a spatula to ensure a uniform bake. Sprinkle the shredded cheese evenly on top, which will melt to create a bubbly, golden layer.
Step 4 – Bake to Perfection
Place the casserole in the preheated oven and bake for 25–30 minutes, or until the cheese on top is fully melted and slightly golden. The casserole should be hot and bubbly throughout.
Step 5 – Serve and Enjoy
Once baked, remove from the oven and let it rest for a few minutes. Serve warm, optionally garnished with fresh thyme or parsley for a touch of color. Pair it with a simple salad or roasted vegetables for a complete meal.
Tips for the Best French Onion Chicken Rice Casserole
- Use cooked chicken from rotisserie or leftover roasted chicken for convenience.
- For a richer flavor, sauté the onions in a mix of butter and olive oil.
- Swiss cheese gives a milder taste, while Gruyère offers a nuttier, more robust flavor.
- Make ahead: Prepare the casserole up to step 3, cover, and refrigerate for up to 24 hours before baking.
- Leftovers store well in the refrigerator for 2–3 days and can be reheated in the oven or microwave.
Frequently Asked Questions
- Can I use uncooked rice?

Absolutely. Just ensure that your French onion dip and any added seasoning are gluten-free. - Can I add vegetables?
Yes! Mushrooms, spinach, or bell peppers can be sautéed with the onions for extra nutrition and flavor. - Can I freeze this casserole?
