What Ingredients You Will Need

This Cheesy Chicken and Wild Rice Casserole uses simple, wholesome ingredients to deliver big flavor and satisfying texture—no fancy stuff, just good food. I love how most of these are pantry staples or fridge regulars, and there’s plenty of room for substitutions if you need to use what you have.

• Chicken breast or thighs, cooked and shredded (about 3 cups / 400g) – Rotisserie chicken works perfectly for convenience. You can also use leftover turkey for a holiday twist.
• Wild rice blend, cooked (3 cups / 450g) – Look for a wild rice blend for the best mix of color and flavor. I like Lundberg or RiceSelect, but any brand will do. Avoid instant rice; it goes mushy.
• Cream of chicken soup (1 can, 10.5 oz / 300g) – You can use low-sodium or substitute with cream of mushroom or celery for a different flavor.
• Sour cream (1 cup / 240g) – Adds a tangy creaminess. Greek yogurt is a good substitute for a lighter version.
• Mayonnaise (½ cup / 120g) – This gives the casserole a rich, velvety texture. If you’re not a fan, just add extra sour cream instead.
• Sharp cheddar cheese, shredded (2 cups / 200g) – Go for sharp or extra-sharp for bold flavor. Pre-shredded is fine, but block cheese melts better.
• Mozzarella cheese, shredded (1 cup / 100g) – For that stretchy, gooey cheese pull! You can swap in Monterey Jack or Swiss if you want a different flavor profile.
• Frozen mixed vegetables (1 ½ cups / 200g) – I usually use a carrot-pea-corn blend, but any combo works. Fresh diced veggies are great too; just sauté them first.
• Onion, finely chopped (1 small / about ½ cup / 75g) – Sautéed for extra flavor, but you can skip if onions aren’t your thing.
• Garlic, minced (2 cloves) – Fresh is best, but jarred works in a pinch.
• Salt and black pepper (to taste) – I start with ½ tsp salt and ¼ tsp pepper and adjust after mixing.
• Italian seasoning or dried thyme (1 tsp) – Gives the casserole a herby, aromatic lift.
• Crispy fried onions (1 ½ cups / 90g) – These go on top and are non-negotiable! French’s is my go-to brand, but any store brand works.
• Fresh parsley, chopped (optional, for garnish) – Adds color and a hint of freshness.

Ingredient Tips: If you need gluten-free, check your soup and onions. For dairy-free, use plant-based cheese and yogurt. Don’t have wild rice? Brown rice is a decent stand-in but won’t have quite the same flavor. The veggies are totally flexible—use up whatever’s in your fridge!

Equipment Needed

• Large saucepan or skillet – For sautéing onions and garlic and mixing the filling. A nonstick pan makes cleanup easier.
• Large mixing bowl – Essential for combining the cooked rice, chicken, veggies, and sauce. I’ve used everything from a basic plastic bowl to a giant salad bowl—anything roomy works.
• 9×13-inch (23x33cm) casserole dish – Glass, ceramic, or metal all work. I lean toward glass so I can peek at the crispy edges.
• Measuring cups and spoons – For accuracy. If you’re like me and occasionally eyeball it, just remember: more cheese is never wrong!
• Wooden spoon or spatula – For stirring everything together. I prefer a silicone spatula for scraping all that cheesy goodness from the bowl.
• Aluminum foil – For covering the casserole so the cheese doesn’t brown too quickly. If you run out, parchment paper is a decent backup.

If you don’t have a big casserole dish, use two smaller dishes or even a deep skillet that’s oven-safe. I’ve even baked this in a Dutch oven during kitchen remodel chaos! Just keep an eye on the baking time if you use something deeper. Hand-wash those nonstick pans gently to keep them lasting longer. And honestly, you don’t need fancy equipment—a sturdy old baking dish and a mixing bowl are all you really need.

How to Make Cheesy Chicken and Wild Rice Casserole with Crispy Onion Topping

1. Cook the Wild Rice:
   
   Prepare 1 cup (180g) of dry wild rice blend according to package instructions (usually about 40-45 minutes simmering in salted water). You’ll want about 3 cups (450g) cooked. Don’t rush this step—undercooked rice will ruin the texture.
   
   Tip: You can cook the rice a day ahead and refrigerate until ready to use. Leftover rice is perfect here!
2. Prepare the Chicken:
   
   If you’re using raw chicken, season 1 lb (450g) chicken breasts/thighs with salt and pepper and roast at 400°F (200°C) for 20-25 minutes or until cooked through. Let cool, then shred or chop. Rotisserie chicken or leftovers make this step fast!
3. Sauté the Aromatics:
   
   In a large skillet over medium heat, add 1 tbsp olive oil. Sauté 1 small chopped onion for 3-4 minutes until translucent, then add 2 minced garlic cloves. Cook another 1 minute until fragrant. Don’t let the garlic brown—it can get bitter!
4. Mix the Filling:
   
   In a big mixing bowl, combine cooked wild rice, shredded chicken, sautéed onions and garlic, 1 ½ cups (200g) frozen mixed veggies, 1 can (300g) cream of chicken soup, 1 cup (240g) sour cream, ½ cup (120g) mayonnaise, 1 tsp Italian seasoning or thyme, ½ tsp salt, ¼ tsp black pepper, 2 cups (200g) shredded cheddar, and 1 cup (100g) mozzarella. Stir until everything is thoroughly combined and evenly coated.
   
   Note: The mixture will look thick and chunky—totally normal.
5. Assemble the Casserole:
   
   Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch (23x33cm) casserole dish. Spoon the mixture in and spread evenly. Press down gently with the back of your spoon for a compact, even layer.
6. Bake (Part 1):
   
   Cover the dish loosely with foil. Bake for 25 minutes. This keeps the cheese gooey and prevents the top from getting too brown too soon.
7. Add the Crispy Onion Topping:
   
   Remove foil and sprinkle 1 ½ cups (90g) crispy fried onions evenly over the top. Return to the oven, uncovered, for another 10-15 minutes or until the onions are golden and the casserole is bubbling around the edges.
   
   Warning: Watch closely in the last few minutes—crispy onions can go from golden to burned fast!
8. Garnish & Serve:
   
   Let the casserole cool for 10 minutes before serving. Sprinkle with chopped fresh parsley if desired. The cooling time helps the casserole set for easier slicing.
   
   Personal tip: If you like extra crunch, serve with more crispy onions on the side!

Cooking Tips & Techniques

• Don’t Overmix: Once you add the rice, mix just until combined. Over-stirring can break down the rice and make it mushy.
• Cheese Choices Matter: I’ve tried this with everything from Swiss to Pepper Jack. Sharp cheddar delivers the boldest flavor, while mozzarella adds creaminess and that satisfying cheese pull. Shred your own cheese for the best melt—pre-shredded is convenient, but sometimes it doesn’t melt as smoothly.
• Troubleshooting Soggy Casserole: If your casserole seems watery, it’s usually because the rice wasn’t fully cooked or drained. Also, frozen veggies can add extra moisture—thaw and pat dry first if you have time.
• Timing is Key: If you’re multitasking (let’s face it, who isn’t?), cook the rice while prepping the chicken, and chop your veggies while the oven preheats. This way, everything comes together super fast.
• Personal Lesson Learned: The first time I made this, I forgot to cover the casserole for the first bake, and the cheese turned hard instead of melty. Always cover for the first half, then uncover to crisp the topping!
• Consistency: If you want a creamier casserole, add an extra ¼ cup (60g) sour cream or a splash of milk before baking.
• Onion Topping Tip: Add the crispy onions just before the final bake. If you add them too soon, they’ll soften up and lose their crunch.

Variations & Adaptations

• Gluten-Free: Use a gluten-free cream soup and double-check that your crispy onions are gluten-free (some brands are!). Substitute with gluten-free panko mixed with olive oil if needed.
• Dairy-Free: Swap in plant-based cheese, mayonnaise, and yogurt for the dairy ingredients, and use a dairy-free cream soup. I’ve tried this with almond-based cheese and coconut yogurt—surprisingly tasty!
• Veggie-Packed: Add sautéed mushrooms, spinach, or bell peppers for extra color and nutrition. Roasted broccoli is my favorite add-in for a little green crunch.
• Different Proteins: Substitute turkey, ham, or even canned tuna for the chicken. Leftover Thanksgiving turkey works beautifully in this casserole (I do this every year!).
• Low-Carb Version: Replace the wild rice blend with riced cauliflower for a lighter, low-carb casserole. The texture is a little different, but still super satisfying.

If you’re feeling creative, swap in different cheeses or add a dash of smoked paprika for a deeper, smokier flavor. I once tossed in a handful of crumbled bacon—nobody complained! The recipe is endlessly adaptable, so don’t be afraid to put your own spin on it.

Serving & Storage Suggestions

This Cheesy Chicken and Wild Rice Casserole is best served hot, straight from the oven with the crispy onion topping at its crunchiest. I like to let it rest for about 10 minutes before slicing to help it hold together on the plate.

• Serving Ideas: Pair with a simple green salad, roasted veggies, or steamed broccoli for a balanced meal. It also goes great with a crusty bread roll for soaking up all that cheesy sauce. For drinks, a light white wine or sparkling apple cider is a solid match.
• Leftovers: Cool the casserole completely, then cover and refrigerate for up to 4 days. The flavors actually get more delicious as they sit—just reheat individual portions in the microwave or pop the whole dish back in a 350°F (175°C) oven until hot and bubbly.
• Freezing: This casserole freezes well before baking. Assemble, skip the crispy onions, cover tightly, and freeze for up to 3 months. Thaw overnight in the fridge, then add the onions and bake as directed.
• Reheating Tips: For best texture, reheat in the oven so the topping stays crispy. If using the microwave, add a fresh sprinkle of onions for crunch.

Honestly, this is one of those casseroles that tastes just as good—maybe even better!—the next day. Makes for an easy lunch or dinner on busy days.

Nutritional Information & Benefits

Per serving (based on 8 servings): approx. 420 calories, 22g protein, 17g fat, 40g carbs, 2g fiber. This casserole is packed with lean protein from chicken, and the wild rice provides a nutty flavor and extra fiber compared to plain white rice. The addition of mixed veggies means you’re sneaking in some vitamins and color, too.

For a lighter version, swap in Greek yogurt for the sour cream and use reduced-fat cheese. If you’re gluten-free, just check your soup and topping labels. The recipe does contain dairy and gluten (from the crispy onions), so keep allergies in mind. Personally, I love knowing I’m serving up a meal with good protein and whole grain wild rice—makes second helpings feel a little less guilty!

How do I keep the crispy onion topping crunchy?
