Some recipes just work — and this easy chicken wild rice casserole is one of them.
It’s the kind of dish that feels like it took all afternoon but comes together
in just over 30 minutes of actual cooking.
A rich, buttery cream sauce wraps around tender chicken, hearty wild rice, and earthy mushrooms,
all baked until bubbling and golden with a satisfying crunch of toasted almonds on top.
I started making a version of this on busy fall weeknights when I needed something that
felt genuinely comforting without chaining me to the kitchen for hours.
The sautéed onion and from-scratch roux make all the difference — this is real comfort food, not a shortcut casserole. One bite and you’ll understand why it’s a contest winner.
Ingredients for This Easy Chicken and Wild Rice Casserole
Every ingredient here pulls its weight. Here’s what goes in and why.
For the Cream Sauce
- Butter – One-third cup builds the roux base that makes this sauce so smooth and rich. Don’t reduce it — the sauce needs it.
- Small onion – Chopped and sautéed until soft, it adds a gentle sweetness that forms the flavor foundation of the entire dish.
- All-purpose flour – One-third cup whisked into the butter creates a proper roux that thickens the sauce without cornstarch or shortcuts.
- Chicken broth – A full 14½-ounce can of chicken broth gives the sauce its savory depth. Low-sodium works great here if you want to control the salt level.
- Half-and-half cream – One cup gives the sauce a creamy richness without being as heavy as pure cream. You can swap in whole milk for a lighter version, though the sauce will be a little thinner.
- Salt and pepper – Seasoned right in the sauce — 1½ teaspoons salt and ½ teaspoon pepper keeps every component well flavored.
For the Casserole Filling
- Cooked chicken – Four cups, shredded or cubed. Rotisserie chicken is your best friend here. Quick, flavorful, and zero extra cooking required.
- Cooked wild rice – Four cups. If you’re cooking it fresh, start it first — wild rice takes about 45 minutes. Or use a pre-cooked pouch to make this a genuinely fast weeknight dinner.
- Sliced mushrooms – Two jars, drained. They add an earthy, savory quality that plays beautifully against the creamy sauce. Fresh cremini mushrooms sautéed in a little butter are an excellent upgrade if you have the time.
- Diced pimientos – One jar, drained. They add a pop of color and a mild sweet pepper flavor that lifts the whole dish. Don’t skip them — they’re a small thing that makes a noticeable difference.
- Fresh parsley – One tablespoon minced, stirred in before baking and sprinkled on top after. It adds a fresh, bright note that cuts through the richness.
- Slivered almonds – One-third cup scattered across the top before baking. They toast in the oven into a nutty, golden crust that gives every bite a satisfying crunch.
Step-by-Step Instructions To Make Easy This Chicken Wild Rice Casserole
Step 1:
Preheat your oven to 350°F. Grease a 2½-quart baking dish and set it aside while you build the filling on the stovetop.
Step 2:
Sauté the onion. Melt the butter in a large saucepan over medium heat. Add the chopped onion and cook, stirring occasionally, for about 5 minutes until it’s soft, translucent, and just starting to turn golden at the edges.
Step 3:
Build the roux. Stir in the flour, salt, and pepper until everything is fully combined with the butter — it should look like a thick paste clinging to the onion. Cook it for about a minute to get rid of the raw flour smell.
Step 4:
Add the broth and thicken the sauce. Pour in the chicken broth gradually, stirring constantly. Bring the mixture to a boil, then stir continuously for about 2 minutes until the sauce is visibly thickened and bubbly. It should coat the back of a spoon cleanly at this point.
Step 5:
Add the cream and remaining filling ingredients. Reduce the heat to medium-low and stir in the half-and-half, cooked chicken, wild rice, drained mushrooms, drained pimientos, and parsley. Stir everything together gently and heat through for 3–4 minutes until the filling is hot and well combined.
Step 6: T
ransfer and top. Pour the filling into the prepared baking dish and spread it into an even layer. Scatter the slivered almonds evenly across the entire surface.
Step 7:
Bake until bubbling. Bake uncovered at 350°F for 30–35 minutes until the filling is visibly bubbling around the edges and in the center, and the almonds have turned a warm, toasted golden brown. Top with an extra pinch of fresh parsley before serving if you like.

Notes
Ingredients
- 1 small onion, chopped
- ⅓ cup butter
- ⅓ cup all-purpose flour
- 1½ teaspoons salt
- ½ teaspoon pepper
- 1 can (14½ oz) chicken broth
- 1 cup half-and-half cream
- 4 cups shredded or cubed cooked chicken
- 4 cups cooked wild rice
- 2 jars (4½ oz each) sliced mushrooms, drained
- 1 jar (4 oz) diced pimientos, drained
- 1 tablespoon minced fresh parsley, plus more for garnish
- ⅓ cup slivered almonds
Instructions
- Preheat oven to 350°F. Grease a 2½-quart baking dish and set aside.
- In a large saucepan over medium heat, melt the butter. Add the chopped onion and sauté for about 5 minutes until soft and translucent.
- Stir in the flour, salt, and pepper until fully combined with the butter and no dry flour remains. Cook for 1 minute.
- Gradually stir in the chicken broth. Bring to a boil, then stir continuously for 2 minutes until the sauce is thickened and bubbly.
- Reduce heat to medium-low. Stir in the half-and-half, cooked chicken, wild rice, mushrooms, pimientos, and parsley. Heat through for 3–4 minutes, stirring gently.
- Transfer the filling to the prepared baking dish. Spread evenly and scatter the slivered almonds across the top.
- Bake uncovered for 30–35 minutes until bubbling throughout and the almonds are toasted golden brown. Garnish with additional parsley if desired and serve immediately.
- Rotisserie chicken shortcut: One large rotisserie chicken yields approximately 4 cups of cooked meat. Shred directly and skip any additional cooking.
- Make ahead: Assemble the filling in the baking dish and refrigerate for up to 2 days. Add the slivered almonds only right before baking to preserve their crunch.
- Fresh mushroom upgrade: Swap jarred mushrooms for 8 oz of fresh cremini mushrooms sautéed in butter for a noticeably deeper flavor.
- Lower sodium version: Use low-sodium chicken broth and reduce the added salt to 1 teaspoon.
- Storage: Refrigerate covered for up to 4 days. Freeze cooled leftovers for up to 2 months. Thaw overnight before reheating at 325°F.
Tips, Tricks & Substitutions For Making This Chicken Wild Rice Casserole Easy
- Use a rotisserie chicken for a genuinely fast dinner. Four cups of cooked chicken comes from roughly one large rotisserie bird. Shred it straight from the store and this casserole comes together in under 20 minutes of hands-on time.
- Make it chicken wild rice casserole with mushrooms — fresh ones. The jarred mushrooms are convenient and work well, but swapping in 8 ounces of fresh cremini mushrooms sautéed in a little butter before adding to the sauce takes the flavor up a noticeable notch.
- Skip the pimientos if you must, but add something. The pimientos are doing quiet flavor and color work. If you don’t have them, a small diced roasted red pepper from a jar works just as well.
- Control the sodium easily. This recipe uses regular canned broth which brings the sodium fairly high. Swap in low-sodium chicken broth and reduce the added salt to 1 teaspoon — it still tastes great and is much more manageable.
- Make it ahead without the almonds. Prepare the entire filling, pour it into the baking dish, cover tightly, and refrigerate for up to 2 days. Add the slivered almonds right before it goes into the oven — otherwise they go soft overnight.
- Swap the almonds for a cracker topping. If you’re serving someone with a nut allergy, crushed Ritz crackers tossed with a tablespoon of olive oil make an equally delicious, equally crunchy topping.
- Storage: Refrigerate leftovers covered for up to 4 days. Reheat at 325°F covered with foil until warmed through, about 20 minutes.
1. Can you make chicken wild rice casserole easy with pre-cooked rice?
Absolutely — and honestly, that’s how most people make it on weeknights. Use a pre-cooked wild rice pouch or leftover wild rice from another meal. Four cups of cooked rice is exactly what you need, and it cuts your total prep time significantly.
2. Can I make chicken and wild rice casserole without canned soup?
Yes — and this recipe proves it. The from-scratch roux made with butter, flour, chicken broth, and half-and-half creates a cream sauce that’s richer and more flavorful than any canned soup version. It takes about 10 extra minutes and makes a real difference.
3. Can I make this chicken wild rice casserole in a crockpot?
You can make a slow cooker version, but the technique shifts slightly. Build the sauce on the stovetop first to get it properly thickened, then combine everything in the slow cooker on LOW for 3–4 hours. Add the almond topping under the broiler for 3–4 minutes at the end to toast them.
4. How do I keep the almonds crunchy on top?
Only add the slivered almonds right before the casserole goes into the oven. If you’re making this ahead, store the filling in the fridge without the almonds and scatter them on top just before baking. They’ll toast perfectly in the oven and stay crisp when served.
5. Can I make chicken wild rice casserole healthy?
To lighten it up, swap the half-and-half for whole milk, reduce the butter to 3 tablespoons, and skip the almonds (or use just a tablespoon for a hint of crunch). The sauce will be slightly thinner but still creamy and flavorful. Adding extra vegetables like diced celery, frozen peas, or fresh spinach stirred in before baking also bumps up the nutrition without changing the spirit of the dish.
