Why I Love This Recipe

I absolutely love this recipe because it’s one-pan magic — minimal prep, minimal cleanup, but maximum comfort. The rice cooks right in the creamy sauce, absorbing every bit of flavor from the broth, mushrooms, and chicken. The result? Perfectly seasoned, moist chicken and rice that’s creamy without being heavy.

The addition of fresh mushrooms adds an earthy depth, while the creamy sauce makes it rich and luxurious. It’s also wonderfully adaptable — you can use leftover chicken, different veggies, or even make it ahead and bake later.

This is the kind of meal you crave on a cozy evening, something that feels indulgent yet wholesome.

• 1 medium onion — finely chopped
• 3 cloves garlic — minced

• 1 cup milk or half-and-half
• 1 cup heavy cream
• 2 tbsp all-purpose flour
• 1 tsp salt (adjust to taste)

Cooking Directions

Step-by-Step Preparation Method

Step 1: Preheat and Prepare

1. Preheat oven to 375°F (190°C).
2. Lightly grease a 9×13-inch baking dish with butter or olive oil.

Step 2: Sear the Chicken

1. Season chicken with salt, pepper, and paprika.
2. Heat olive oil in a skillet over medium heat.
3. Sear chicken for 2–3 minutes per side until lightly golden (no need to cook through).
4. Remove chicken and set aside.

Step 3: Make the Creamy Mushroom Sauce

1. In the same skillet, melt butter and add onions. Sauté for 2 minutes until translucent.
2. Add mushrooms and cook for 5–6 minutes until soft and lightly browned.
3. Stir in garlic and cook for 30 seconds.
4. Sprinkle flour over mushrooms and stir to coat.
5. Gradually add chicken broth, stirring to avoid lumps.
6. Pour in milk and cream, stirring until sauce thickens slightly (about 3–4 minutes).
7. Stir in thyme, salt, pepper, and Parmesan cheese (if using).

Step 4: Assemble the Casserole

1. Spread uncooked rice evenly in the prepared baking dish.
2. Pour the mushroom sauce over the rice.
3. Gently stir to mix sauce and rice together.
4. Arrange seared chicken pieces on top.
5. Cover tightly with foil.

Step 5: Bake

1. Bake covered for 40 minutes.
2. Remove foil and bake uncovered for an additional 15–20 minutes, or until rice is tender and most of the liquid is absorbed.
3. Check for doneness — chicken should be fully cooked (internal temperature 165°F / 74°C).

Step 6: Rest and Serve

1. Let casserole rest for 5–10 minutes before serving.
2. Garnish with chopped parsley and extra Parmesan cheese.

How to Serve

Serve hot, straight from the casserole dish. This dish pairs beautifully with:

• A fresh green salad (like Caesar or garden salad)
• Garlic bread or crusty dinner rolls
• Steamed green beans or broccoli for added veggies

For a comforting dinner, serve it family-style at the table, letting everyone scoop their own portion.

Recipe Tips

• Use long-grain rice (like basmati or jasmine). Short-grain rice can get mushy.
• Don’t skip searing the chicken — it adds great flavor and texture.
• If you prefer a shortcut, use rotisserie chicken and reduce baking time by 15 minutes.
• You can add frozen peas or carrots for color and nutrition.
• For extra creaminess, stir in a few tablespoons of sour cream before baking.

Recipe Variations

• Cheesy Chicken & Rice Casserole: Add 1 cup shredded cheddar or mozzarella cheese before baking.
• Broccoli Chicken Rice Bake: Mix in steamed broccoli florets with the rice.
• Wild Rice Version: Replace white rice with a wild rice blend for a nutty, hearty flavor.
• Dairy-Free: Use coconut milk and olive oil instead of cream and butter.
• Mushroom Lovers’ Version: Use a mix of cremini, shiitake, and portobello mushrooms for depth.
• Spicy Twist: Add red pepper flakes or a splash of hot sauce to the sauce for heat.

Freezing and Storage

• Refrigeration: Store leftovers in an airtight container for up to 4 days.
• Freezing: Cool completely, then freeze for up to 3 months.
  • Thaw overnight in the fridge before reheating.
• Reheating: Cover with foil and reheat in oven at 350°F (175°C) for 20 minutes, or microwave individual portions.

Special Equipment Needed

• 9×13-inch baking dish
• Large skillet or sauté pan
• Mixing spoon or whisk
• Aluminum foil
• Oven

Frequently Asked Questions (FAQ)

Q1: Can I use brown rice instead of white rice?
Yes, but increase the baking time by 15–20 minutes and add ½ cup extra broth since brown rice takes longer to cook.

Q2: Can I use canned cream of mushroom soup?
Yes! For a quicker version, use two cans of condensed cream of mushroom soup mixed with 1 cup of milk instead of making homemade sauce.

Q3: Can I prepare this in advance?
Absolutely! Assemble everything up to the baking step, cover, and refrigerate for up to 24 hours. Bake when ready.

Q4: My rice is still undercooked. What happened?
If using a different baking dish or oven temperature, cooking time can vary. Just cover again, add ½ cup broth, and bake 10–15 minutes more.

Q5: Can I make it vegetarian?
Yes! Replace chicken with chickpeas or sautéed mushrooms and use vegetable broth.
