Ingredients You’ll Need

Ingredients for a chicken broccoli and wild rice casserole recipes from scratch, with broccoli and cheese, on a white table.

For the “Main” Ingredients:

A Wild Rice Blend: You’ll need 1 cup of a wild rice blend (you can usually find this in a box or the bulk aisle).

Ellie’s Tip: I find that a blend of wild and brown or white rice is just perfect! 100% pure wild rice can take a very long time to cook and has a very strong flavor. A blend is the secret to the perfect, nutty, tender bite!

Cooked Chicken: About 3 cups, shredded or diced.

Ellie’s Lifesaver Tip: A store-bought rotisserie chicken is my favorite shortcut for this recipe! It’s so flavorful and makes this casserole come together in a snap.

Fresh Broccoli Florets: About 3 cups, cut into small, bite-sized pieces. We’ll blanch these to keep them bright green!

For Our “From-Scratch” Creamy Cheese Sauce:

Unsalted Butter: 1/4 cup (that’s half a stick).
Onion: 1 small yellow onion, finely diced.
Garlic: 2 cloves, minced.
All-Purpose Flour: 1/4 cup. This is what will make our sauce thick and creamy!
Low-Sodium Chicken Broth: 1 1/2 cups.
Whole Milk: 1 1/2 cups. (You can also use 2% milk, but whole milk makes it so much richer!)
Sharp Cheddar Cheese: 2 cups, freshly shredded.

Ellie’s Tip: I promise, it’s worth the extra minute to shred your own cheese from a block! The pre-shredded bagged cheese has a coating that can sometimes make your sauce a little grainy.

Salt & Pepper: To taste.

For the Crispy Topping (Optional, but so good!):

Panko Breadcrumbs: 1/2 cup.
Melted Butter: 1 tablespoon.
More Cheddar Cheese: About 1/2 cup for sprinkling!

Step-by-Step Instructions

1. Cook Your Rice

First, let’s get our rice going, as it takes the longest! Cook your 1 cup of wild rice blend according to the package directions. This usually takes about 40-45 minutes. Once it’s done, just fluff it with a fork and set it aside.

2. Prep Your Chicken & Broccoli

For the Chicken: If you’re not using a rotisserie chicken, just poach or bake 1.5 lbs of boneless, skinless chicken breasts until they’re cooked through, then shred them. You’ll want about 3 cups!
For the Broccoli (My “Bright Green” Secret!):
- Ellie’s Tip: We need to blanch our fresh broccoli! Bring a small pot of salted water to a boil. Add your 3 cups of broccoli florets and let them cook for just 2 minutes.
- While they’re boiling, fill a large bowl with ice and water. After 2 minutes, use a slotted spoon to move the broccoli right into the ice bath. This instantly stops the cooking and is the secret to a broccoli chicken wild rice casserole where the broccoli is bright green, crisp-tender, and not mushy or grey!

3. Make the Creamy Cheese Sauce

This is the from-scratch magic, and it’s so easy!

In a large pot or Dutch oven, melt your 1/4 cup of butter over medium heat. Add your finely diced onion and sauté for 5-6 minutes, until it’s soft and sweet.
Stir in your 2 cloves of minced garlic and cook for 1 more minute until you can smell it.
Sprinkle the 1/4 cup of all-purpose flour all over the onions. Whisk it constantly for 1-2 minutes. This is our “roux,” and it’s what makes the sauce thick and creamy!
Slowly pour in your 1 1/2 cups of chicken broth, whisking as you go to keep it all smooth. Then, whisk in your 1 1/2 cups of milk.
Let the sauce simmer, stirring often, for 3-5 minutes, until it’s lovely and thick (like a thin gravy).
Turn the heat down to low. Now, stir in your 2 cups of freshly shredded cheddar cheese! Stir until the cheese is completely melted. Add a little salt and pepper to taste.

4. Combine Everything!

This is the best part. In your largest mixing bowl, add your cooked wild rice, your 3 cups of shredded chicken, and your bright green, blanched broccoli florets.

Now, pour that beautiful, creamy cheese sauce all over the top! Fold everything together gently with a large spatula until every single piece is coated in that wonderful sauce.

Ellie’s Top Tips for Success

Here are my three little secrets for the perfect chicken broccoli and wild rice casserole!

1. The Rotisserie Chicken Shortcut! This is my “lifesaver” tip for a busy weeknight! Using a pre-cooked rotisserie chicken makes this recipe come together so fast and adds so much wonderful flavor!
2. You Must Blanch Your Broccoli! Please don’t skip this! A quick, 2-minute dip in boiling water (and then an ice bath) is the only way to get that beautiful, bright green, crisp-tender broccoli in your finished casserole (instead of sad, mushy, grey broccoli!).
3. The Make-Ahead Magic Plan This is the perfect make-ahead meal! Just assemble the entire casserole, but leave off the Panko topping. Cover and keep it in the fridge for up to 2 days. When you’re ready, let it sit out for 30 minutes, add the topping, and bake! (It may need 10-15 extra minutes).

Storing & Reheating Leftovers

To Store: This is one of my favorite leftovers for lunch! Just let the casserole cool down completely, then cover your baking dish tightly with foil, or move the leftovers to an airtight container. It will keep beautifully in the refrigerator for 3 to 4 days.
To Reheat (My Favorite Way!): The oven is the best way to get that topping a little crispy again! Just place a scoop in a small, oven-safe dish. I like to sprinkle it with a tiny splash of chicken broth or milk (just a tablespoon!) to keep it creamy. Cover it with foil and bake at 350°F (175°C) for 15-20 minutes, or until it’s hot and bubbly!

Common Questions (FAQ)

Can I use 100% pure wild rice instead of a blend?

My honest answer is that I don’t recommend it for this recipe! 100% pure wild rice has a very strong, earthy flavor and can take over an hour to cook (and it’s very chewy!). A “wild rice blend” is the secret to the perfect, balanced, nutty flavor and a tender texture that matches the chicken and broccoli!

Can I use canned “cream of” soup in a hurry?

Oh, you absolutely can if you’re in a real pinch (you’d need about 2 cans, like one cream of chicken and one cream of mushroom). But I do hope you’ll try my from-scratch sauce! It only takes about 10 minutes, has no preservatives, and the fresh, cheesy flavor is just a million times better!

Can I use frozen broccoli?

Yes! This is a great shortcut. Just let the broccoli thaw completely, and then this is the most important part! Pat it very, very dry with paper towels before you add it to the mix. If you add it while it’s still wet or frozen, it can make your lovely, creamy casserole watery.

Can I freeze this casserole?

Yes! This is a wonderful freezer meal.

To Freeze Unbaked: Assemble the whole casserole (but leave off the Panko topping!). Cover it tightly with foil and freeze. Let it thaw overnight in the fridge, then add the topping and bake as directed (it may need 10-15 extra minutes).
To Freeze Baked: You can also freeze the finished, baked casserole! Let it cool completely, then cover it. Reheat it from frozen (covered with foil) at 350°F for about an hour, or until it’s hot and bubbly.
