Chicken Wild Rice Casserole Recipe Cream of Mushroom: Homestyle Creamy Bake

This casserole brings hearty comfort to any table with its creamy texture and rich flavors. I developed this version after years of testing different wild rice blends and cream bases.

Wild rice adds nutty depth while the mushroom sauce creates the perfect velvety binder. The chicken stays tender through baking, and the top forms a golden crust that seals in all those savory flavors.

What you get is a dish that feels special enough for Sunday dinner but simple enough for a weeknight. The combination of wild rice, chicken, and cream of mushroom creates a satisfying one-dish meal.

Bake until bubbling and golden for the ultimate homestyle experience. This recipe delivers every time.

Ingredients for Chicken Wild Rice Casserole Recipe Cream of Mushroom

Hearty, creamy, and packed with wild rice and chicken. Probably have most already.

The wild rice blend is non-negotiable for that nutty bite—Lundberg or Near East brands at most grocery stores have great options. I grab mine in bulk at Whole Foods when I’m stocking up. Chicken breasts stay juicier if you don’t overcook them before baking, so cut them into even, bite-sized pieces. For the mushrooms, creminis add more flavor than white, but either works (just avoid the pre-sliced kind—they get mushy).

No cream of mushroom soup? Homemade bechamel with mushrooms works in a pinch (equal parts butter, flour, milk cooked with sautéed mushrooms). Sour cream can be swapped for Greek yogurt at the same amount. If you’re out of fresh mushrooms, canned or frozen (thawed and drained) are fine. For a richer topping, mix the cheddar with Parmesan or Gruyère—just shred it yourself for the best melt.

Assemble and refrigerate overnight if you want to prep ahead—actually improves the flavor. Baked casserole keeps in the fridge for 3-4 days and freezes beautifully for 3 months. Leftovers reheat like a dream (cover with foil to prevent drying).

Step-by-Step Instructions for Chicken Wild Rice Casserole

This method delivers a creamy, comforting bake with minimal hands-on time.

Step 1: Cook the Wild Rice Blend

In a medium saucepan, combine the 1.5 cups Wild Rice Blend and 2.5 cups Chicken Broth. Bring to a boil over high heat, then reduce to low, cover, and simmer for 40-45 minutes until the rice is tender and the liquid is absorbed.

I like to fluff the cooked rice with a fork to separate the grains. If you’re using long-grain brown rice instead, it’ll take closer to 45 minutes. Set this aside while you prep the rest—it’s okay if it’s still warm.

Step 2: Sauté the Vegetables and Chicken

In a large skillet, melt the 0.25 cup Butter over medium heat. Add the 1 whole Yellow Onion (finely diced) and 2 pieces Celery Stalks (also diced), and cook for 3-4 minutes until softened.

Add the 8 oz Fresh Mushrooms (sliced) and cook for another 4-5 minutes until they release their moisture and start to brown. Stir in the 3 cloves Garlic Cloves (minced) and cook for 30 seconds until fragrant.

Push the veggies to one side and add the 2 lb Boneless Skinless Chicken Breasts (cut into bite-sized pieces). Cook for 5-6 minutes until the chicken is no longer pink, stirring occasionally. Sprinkle with the 1 tsp Dried Thyme, 1 tsp Salt, and 0.5 tsp Black Pepper while it cooks.

Step 3: Combine Everything into a Creamy Sauce

Sprinkle the 0.25 cup All-Purpose Flour over the chicken and veggies, stirring to coat evenly. Cook for 1 minute to remove the raw flour taste.

Slowly pour in the 2 cans Cream of Mushroom Soup, stirring constantly to incorporate. Then, stir in the 1 cup Sour Cream until the sauce is smooth and creamy. This is where the magic happens—keep the heat low to avoid curdling.

Fold in the cooked wild rice blend and mix until everything is evenly coated. The sauce should be thick and luscious, clinging to the rice and chicken. If it seems too thick, add a splash of broth to loosen it.

Step 4: Bake Until Bubbly and Golden

Transfer the mixture to a greased 9×13-inch baking dish and spread it out evenly. Sprinkle the 1.5 cups Shredded Cheddar Cheese uniformly over the top, covering every inch for that perfect golden crust.

Bake in a preheated 375°F oven for 20-25 minutes until the casserole is bubbling around the edges and the cheese is melted and golden brown. For extra browning, broil for 1-2 minutes at the end, but watch it closely to avoid burning.

Let it rest for 5 minutes before serving—this helps the casserole set slightly so it’s easier to scoop. The cheese should stretch with every serving, and the sauce should be rich and velvety.

Creative Variations of This Dish

Southern Style

For a true Georgia twist, swap the cheddar for sharp white cheddar and add ½ cup diced pimento peppers to the chicken mixture. I love how the sweetness of pimentos complements the nutty wild rice. 🌟

Creamy Herb Variation

Stir 2 tbsp chopped fresh parsley and 1 tbsp fresh tarragon into the sauce before baking. The herbs brighten the rich cream of mushroom base beautifully. I grow both in my Atlanta garden.

Spicy Kick

Add 1 diced jalapeño with the onions and ½ tsp cayenne pepper to the sauce. This gives a nice heat without overpowering the dish. Perfect for those who like a little fire with their comfort food.

Vegetable Boost

Mix in 1 cup frozen peas and 1 cup diced carrots when combining everything. The veggies add color and texture while keeping it hearty. I often use this version for Sunday suppers. 💪

Gluten-Free Adaptation

Use gluten-free cream of mushroom soup and swap the all-purpose flour for cornstarch. The texture remains just as creamy. Many stores now carry Pacific Foods gluten-free options.

Lighter Version

Replace the sour cream with Greek yogurt and use low-fat cheddar. You reduce the calories but keep all the comfort. I recommend Fage 2% for the best texture. ✨
