French Onion Chicken Rice Casserole

There’s something incredibly comforting about a warm, cheesy casserole, and this French Onion Chicken Rice Casserole tops the list of my favorites. It’s an easy dish to make that brings together tender chicken, creamy soups, and a rich onion flavor. Every bite reminds me of cozy family dinners, and guess what? It only takes about an hour from start to finish!

What Makes This So Good:

  • Flavorful: The caramelized onions add a sweet richness that complements the creamy broth perfectly.
  • Cheesy Goodness: A generous layer of melted Swiss or mozzarella cheese on top makes it irresistible!
  • Simple Prep: With straightforward steps, this casserole comes together effortlessly.

Ingredients:

  • 2 cups (300g) cooked, shredded chicken
  • 1 cup (200g) uncooked long grain white rice
  • 1 (10.5 oz / 300g) can French onion soup
  • 1 (10.5 oz / 300g) can cream of chicken soup
  • 1 ½ cups (170g) shredded Swiss or mozzarella cheese
  • ½ cup (120ml) milk
  • 1 tablespoon (14g) butter
  • 1 small onion, thinly sliced
  • Salt and black pepper to taste
  • Fresh thyme or parsley for garnish (optional)

Smart Swaps:

  • Cream of Mushroom Soup: Swap the cream of chicken soup for cream of mushroom to make it vegetarian.
  • Brown Rice: Use brown rice for added fiber; just be sure to adjust cooking time accordingly.
  • Dairy-Free Cheese: Try a dairy-free cheese alternative for a lactose-free option.

Sourcing Tips:

When selecting your onions, look for ones that are firm and heavy for their size, which indicates freshness. For the best flavor, consider using high-quality, low-sodium French onion soup brands.

Directions:

  1. Preheat the oven to 350°F (175°C). Grease a 9×13-inch (23×33 cm) baking dish.
  2. Sauté Onions: In a skillet, melt the butter over medium heat. Add the sliced onions and sauté until caramelized, about 10-12 minutes. Set aside.
  3. Mix Ingredients: In a large bowl, combine the uncooked rice, French onion soup, cream of chicken soup, milk, salt, and pepper.
  4. Add Chicken and Cheese: Stir in the cooked chicken and half of the shredded cheese until well combined.
  5. Assemble Casserole: Pour the mixture into the prepared baking dish and spread evenly. Top with the caramelized onions and the remaining cheese.
  6. Bake Covered: Cover with foil and bake for 45 minutes.
  7. Final Touch: 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: Sprinkle with fresh thyme or parsley before serving, if desired.

Pro Tips:

  • Make-Ahead: Assemble the casserole a day in advance; just cover and refrigerate. Bake it when you’re ready!
  • Transport: Perfect for potlucks; simply cover with foil and reheat before serving.
  • Re-Crisping: If you want that cheese topping nice and crispy again, pop it under the broiler for a minute or two right before serving.

Variations:

  1. Vegetable Add-In: Mix in vegetables like spinach or broccoli for added nutrients.
  2. Herb Flavored: Experiment with dried herbs like rosemary or oregano for a different flavor profile.
  3. Spicy Kick: Add a dash of hot sauce or red pepper flakes for a spicy twist.

Serving, Storage, and Reheat Guidance:

Serve this casserole warm as a hearty main dish alongside a simple green salad or some crusty bread. For leftovers, let the casserole cool completely, then store it in an airtight container in the fridge for up to 3 days. Reheat portions in the microwave or oven until warmed through, ensuring that the center reaches at least 165°F (74°C) for safety.

FAQs:


  1. Can I use leftover turkey instead of chicken?
    Absolutely! Leftover turkey works wonderfully in this recipe for a post-holiday dish.



  2. How can I make this dish gluten-free?
    Ensure that your soups are gluten-free, and use gluten-free rice in place of regular rice.



  3. Can I freeze the casserole?
    Yes, you can freeze it before baking! Just cover it tightly and store it for up to 3 months. Thaw in the fridge overnight before baking.


Dive into this cozy casserole; I promise it’ll become a cherished recipe in your household, just like it is in mine!
