Ingredients Breakdown

Below is the full ingredient list exactly as provided, grouped for clarity. This recipe yields 6 portions.

For the Casserole

• 3 cups cooked white rice
  Substitute with brown rice for nuttiness.
• 2 cups shredded cooked chicken
  Use rotisserie chicken or leftover turkey.
• 1 can cream of chicken soup
  Low-sodium or homemade alternatives.
• 1 can French onion soup
• 1 cup sour cream
  Dairy-free yogurt can be used.
• 1 cup shredded cheese (Mozzarella or Swiss)
  Mozzarella for milder taste, Swiss for nuttier.
• 1 cup French fried onions
  Divide for topping and inside the casserole.
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• Salt, to taste
• Black pepper, to taste
• 1/4 cup chopped parsley
  For garnish.

Tools & Equipment Needed

• 9×13-inch baking dish – ensures even baking and plenty of surface area for crisping the top.
• Large mixing bowl – big enough to combine all ingredients without spilling.
• Spatula – helpful for folding ingredients and spreading the casserole evenly.
• Measuring spoons – essential for accurate seasoning.
• Oven mitts – the casserole gets hot!
• Cutting board and knife – for chopping parsley.

Step-by-Step Instructions

Below is the recipe exactly as provided—kept precise and intact—along with expanded explanations to guide cooks through each stage.

1. Preheat the Oven

Preheat the oven to 350°F (175°C).
This moderate temperature allows the casserole to heat through evenly while the cheese melts and the mixture becomes creamy without drying out.

Prepare a large mixing bowl to hold all the ingredients.

2. Mix the Casserole Base

In your bowl, combine:

• 3 cups cooked white rice
• 2 cups shredded cooked chicken
• 1 can cream of chicken soup
• 1 can French onion soup
• 1 cup sour cream
• 1 cup shredded cheese (Mozzarella or Swiss)
• 1 cup French fried onions
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• Salt and black pepper to taste

Stir thoroughly until the mixture is cohesive, creamy, and evenly combined.

What’s happening here:
The two soups create the silky binder that gives this casserole its signature texture. The sour cream adds body and richness. Mozzarella or Swiss melts into the mixture, making it velvety while the French fried onions inside the mixture contribute crunch, savoriness, and depth.

3. Transfer to the Baking Dish

Lightly grease a 9×13-inch baking dish.
Spread the mixture evenly across the dish, smoothing the top with a spatula.

This ensures even heating and prevents any dry edges.

4. Bake the Casserole

Bake uncovered for about 30 minutes, or until the edges are bubbling.

Why uncovered?
You want evaporation to thicken the casserole slightly while letting the top begin to turn golden.

5. Add the Final Crispy Topping

Sprinkle the remaining ½ cup of French fried onions on top.
Return the casserole to the oven for an additional 5 minutes.

This final bake crisps up the onions so they stay crunchy and fragrant.

6. Garnish and Serve

Remove the casserole from the oven and sprinkle with chopped parsley.
Let it rest for 5–10 minutes before serving so the mixture can settle.

Tips & Variations

Make it vegetarian

Substitute the shredded chicken with:

• sautéed mushrooms
• cooked lentils
• diced roasted vegetables

And replace the cream of chicken soup with cream of mushroom soup.

Vegan adaptation

• Use dairy-free yogurt instead of sour cream
• Use vegan cheese
• Choose vegan cream soup alternatives
• Add plant-based chicken strips or extra vegetables

Gluten-free adjustments

Many French fried onion brands contain gluten. Use a gluten-free option if needed. All other ingredients can be purchased gluten-free.

Dairy-free option

• Swap sour cream for dairy-free yogurt
• Replace cheese with a dairy-free melting cheese

Boost the vegetables

Mix in:

• peas
• spinach
• roasted carrots
• sautéed onions

Anything mild and tender works well with the French onion base.

Adjust the richness

For a lighter casserole, use light sour cream and reduce cheese slightly.

Flavor Profile & Pairings

This casserole leans heavily into savory, creamy, and aromatic flavors. French onion soup delivers a subtle sweetness with slow-cooked onion depth, while the cream of chicken soup provides comforting richness.

The texture is hearty and spoonable, with tender chicken, soft rice, and small bursts of crunch from the French fried onions.

Best side dishes
