Overview

A creamy baked casserole with tender chicken, earthy mushrooms, fluffy rice, and nutty melted Gruyère cheese—basically a more elevated version of classic chicken-and-rice.

 Ingredients (Serves 4–6)

 Protein

• 2 cups cooked chicken (shredded or diced)
  • Rotisserie chicken works great

 Vegetables

• 2 tbsp butter or olive oil
• 1 medium onion (finely chopped)
• 3 cloves garlic (minced)
• 250–300g mushrooms (sliced; cremini or button)

 Rice

• 1 cup uncooked long-grain white rice
  (or 3 cups cooked rice)

 Creamy Base

• 2 cups chicken broth
• 1 cup milk or half-and-half
• 2 tbsp flour (for thickening)
• ½ cup sour cream (optional but recommended)

 Cheese

• 1–1½ cups grated Gruyère cheese
• ¼ cup Parmesan (optional, for depth)

 Seasoning

• 1 tsp thyme (dried or fresh)
• ½ tsp paprika
• Salt & black pepper (to taste)

 Optional Add-ins

• Spinach or peas
• Caramelized onions
• Splash of white wine (for mushrooms)

 Instructions

1. Cook the rice (if using uncooked)

• Cook 1 cup rice with 2 cups water or broth
• Set aside (slightly undercooked is ideal)

 Skip if using pre-cooked rice

2. Sauté vegetables

In a large pan:

• Heat butter/oil
• Add onions → cook until soft (4–5 min)
• Add garlic → cook 30 seconds
• Add mushrooms → cook until browned and moisture evaporates (8–10 min)

 Tip: Don’t overcrowd the pan or mushrooms will steam instead of brown.

3. Make creamy sauce

• Sprinkle flour over mushrooms → stir 1 minute
• Slowly add chicken broth while stirring
• Add milk → simmer until thickened (3–5 min)
• Stir in sour cream
• Season with thyme, paprika, salt, pepper

4. Combine filling

In a large bowl or pan mix:

• Cooked rice
• Chicken
• Mushroom sauce
• Half of the Gruyère cheese

5. Assemble casserole

• Transfer mixture into greased baking dish
• Top with remaining Gruyère + Parmesan

6. Bake

• Bake at 180°C (350°F) for 25–30 minutes
• Optional: broil 2–3 minutes for golden top

7. Rest & serve

• Let sit 5–10 minutes before serving
• This helps it firm up

 Flavor & Texture

• Creamy, cheesy interior
• Slightly crispy top layer
• Deep umami from mushrooms
• Nutty richness from Gruyère
