Ingredients You’ll Need
The ingredients in this Slow Cooker Chicken Broccoli Rice Casserole Recipe are simple but carefully chosen to create the perfect balance of flavors and textures. Brown rice is a must here—you’ll see why later! Choosing fresh broccoli and good quality chicken will make a noticeable difference in flavor, so I recommend picking the best you can find.
- Small onion: Adds sweetness and depth, plus the slow cooker mellows its flavor beautifully.
- Long grain brown rice: The star carb here; don’t sub for white or other rice types because the cooking times and absorbency vary.
- Dijon mustard: I love how a little tangy punch wakes up the flavors without overpowering.
- Garlic powder: For that cozy garlicky background that’s not too intense and easy to blend.
- Dried thyme: Brings a subtle earthiness that pairs perfectly with chicken and broccoli.
- Salt & black pepper: Essential for seasoning all the layers evenly.
- Low sodium chicken broth: Keeps the dish from being too salty and ensures a rich cooking liquid for the rice.
- Boneless skinless chicken breasts: Lean and perfect for shredding or cutting into bite-sized pieces after cooking.
- Broccoli: Fresh is best; chop into small florets for even cooking and easy eating.
- Plain Greek yogurt (optional): Adds creaminess and a gentle tang without heaviness—definitely a game changer.
- Parmesan cheese: Sharp and nutty, this helps deepen the cheesy flavor profile.
- Shredded cheddar cheese: Melts wonderfully to give you that classic comforting casserole vibe.
Variations
I love experimenting with this Slow Cooker Chicken Broccoli Rice Casserole Recipe depending on what’s in my fridge and what my family is craving. Don’t hesitate to swap in your favorite cheese or add in extras for more texture or flavor.
- Add mushrooms or bell peppers: I’ve tossed in diced mushrooms before for extra savoriness, and colorful bell peppers for a sweet crunch.
- Use cauliflower rice for low-carb: If you’re watching carbs, try swapping the brown rice with cauliflower rice—it won’t need as much cooking time, so add it toward the end.
- Spice it up: Add a pinch of smoked paprika or red pepper flakes if you like a little heat—I always ask my family before turning up the spice!
- Dairy-free version: Skip the yogurt and cheese, and add some coconut milk or cashew cream for creaminess instead.
How to Make Slow Cooker Chicken Broccoli Rice Casserole Recipe
Step 1: Layer Your Base Ingredients
Start by tossing the chopped onion, rinsed brown rice, Dijon mustard, garlic powder, dried thyme, salt, and pepper into the bottom of your slow cooker. Stir everything up a bit to combine. This layering is key because the rice needs direct contact with the broth to cook evenly and soak up all that flavor.
Step 2: Pour in Broth and Add Chicken
Pour the low sodium chicken broth evenly over your rice mixture, then give it a quick stir. Place the boneless skinless chicken breasts right on top, and sprinkle with a little extra black pepper. I like doing this because the chicken juices mingle with the rice as they cook, making the whole dish super flavorful.
Step 3: Slow Cook to Perfection
Cover your slow cooker and set it on high for about 2 ½ to 3 ½ hours. My cooker typically needs 3 hours on high to get the rice fully tender and the chicken cooked through. You’ll know it’s ready when the rice has absorbed almost all the broth and the chicken reaches an internal temperature of 165°F (74°C).
Step 4: Cook the Broccoli Separately
While the chicken and rice finish cooking, steam your broccoli separately. I tried adding broccoli straight into the slow cooker at the end, but it turns a dull green and loses that fresh snap I love. Steaming on the stove brings out the vibrant color and keeps the texture just right.
Step 5: Combine and Add Creamy Goodness
Once the rice and chicken are done, carefully remove the chicken to a cutting board and shred or dice it. Stir the plain Greek yogurt (if using!), Parmesan, and shredded cheddar cheese into the rice mixture in the slow cooker until beautifully melty and creamy. Then gently fold in the cooked broccoli and chicken pieces, making sure everything is evenly distributed.
Step 6: Serve and Enjoy
Give it a nice stir, taste for seasoning, and you’re ready to dig in! This Slow Cooker Chicken Broccoli Rice Casserole Recipe is perfection served straight from the pot—comfort food that’s healthy too.
Pro Tips for Making Slow Cooker Chicken Broccoli Rice Casserole Recipe
- Don’t Skip Rinsing the Rice: Rinsing the brown rice removes excess starch and prevents the casserole from becoming gummy.
- Check for Liquid Levels: Different slow cookers vary in heat intensity, so check moistness 30 minutes before the end—add a splash of broth if it’s drying out.
- Steaming Broccoli Separately: For the best color and texture, steam your broccoli on the stove instead of adding it directly to the slow cooker.
- Add Yogurt Off Heat: Stir in Greek yogurt after cooking to keep it creamy and prevent curdling.
How to Serve Slow Cooker Chicken Broccoli Rice Casserole Recipe
Garnishes
I often sprinkle a little extra Parmesan on top before serving, just for that salty, nutty finish. A scattering of chopped fresh parsley or basil adds a burst of color and freshness that makes it feel even more homemade. If you’re feeling adventurous, a light drizzle of good-quality olive oil or a dash of paprika on top adds a lovely inviting aroma.
Side Dishes
Since this casserole is a complete meal on its own, I usually keep sides simple. A crisp green salad with lemon vinaigrette pairs beautifully and adds some crunch. Garlic bread or crusty artisan rolls soak up any extra sauce and make the meal feel extra cozy. Sometimes, roasted root vegetables or a fresh fruit salad balance the richness nicely.
Creative Ways to Present
For family dinners or meal-prep, I like serving this casserole in individual ramekins—everyone gets their own warm, cheesy portion, and it looks pretty on the table. For holidays or guests, topping with toasted breadcrumbs mixed with Parmesan before serving gives it a delightful crunch and a restaurant-worthy touch.
Make Ahead and Storage
Storing Leftovers
Leftovers of this Slow Cooker Chicken Broccoli Rice Casserole Recipe keep wonderfully in an airtight container in the fridge for up to 3 days. I let it cool completely before refrigerating to preserve creaminess and freshness. Reheating gently helps keep everything tasting just as good as day one.
Freezing
I’ve frozen this casserole a few times and found it freezes well—just cool completely, portion it into freezer-safe containers, and freeze for up to 3 months. When you’re ready to enjoy, thaw overnight in the fridge before reheating for best results. Freezing works great if you want to prep meals ahead for busy weeks!
Reheating
To reheat, I prefer warming leftovers in the oven at 350°F (175°C) covered with foil to avoid drying out—about 20 minutes usually does the trick. If you’re short on time, microwave on medium heat in bursts, stirring in between. Adding a splash of broth or water helps maintain that creamy texture.
FAQs
-
Can I use white rice instead of brown rice in this Slow Cooker Chicken Broccoli Rice Casserole Recipe?
It’s best not to substitute white rice for brown in this recipe. Brown rice takes longer to cook and absorbs liquid differently, which is accounted for in the cooking time and liquid amount. Using white rice would result in overcooked or mushy rice unless you adjust times and broth carefully.
-
Can I prepare this casserole in advance and refrigerate before cooking?
Yes! You can assemble the casserole ingredients in the slow cooker insert, cover tightly, and refrigerate overnight. The next day, add the chicken broth and cook as directed, adding extra cooking time since the ingredients will be cold. This makes it easy to prep ahead and have dinner ready when you are.
-
How can I add more vegetables to this slow cooker casserole?
Feel free to toss in diced carrots, peas, or mushrooms with the onions and rice at the beginning of cooking. Just keep in mind the total liquid ratio, as extra veggies may absorb more broth. You can also sprinkle fresh herbs on top after cooking for added flavor.
-
Is it okay to add the broccoli directly to the slow cooker?
You can add broccoli to the slow cooker during the last hour of cooking, but it tends to lose its bright green color and becomes very soft. I prefer steaming it separately to keep it vibrant with a slight bite, which adds nice texture contrast to the creamy casserole.
Final Thoughts
This Slow Cooker Chicken Broccoli Rice Casserole Recipe is one of those meals that feels like a warm hug on a plate. I absolutely love how it turns out—comforting, creamy, but still balanced and fresh with the broccoli’s green pop. It’s so satisfying to know you can have a wholesome, delicious dinner ready with minimal effort—and that’s a game changer on busy days. I hope you give this recipe a try soon and find it a staple in your slow cooker rotation just like we have. Trust me, once you get the hang of it, you’ll want to make it again and again!

Ingredients
Main Ingredients
- 1 small onion, chopped
- 1 cup long grain brown rice, rinsed and drained (do NOT substitute white rice or any other type of rice)
- 1 tablespoon Dijon mustard
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 cups low sodium chicken broth
- 1 pound boneless skinless chicken breasts
- 1 pound broccoli, cut into small pieces
- 1/2 cup plain Greek yogurt, optional, for extra creaminess
- 1/2 cup grated Parmesan cheese
- 1 cup shredded cheddar cheese
Instructions
- Combine Base Ingredients: Place the chopped onion, rinsed brown rice, Dijon mustard, garlic powder, dried thyme, salt, and black pepper into the bottom of your slow cooker. This mixture forms the flavorful foundation of the casserole.
- Add Broth and Stir: Pour in the low sodium chicken broth over the dry ingredients and stir well to combine everything evenly. This will help the rice cook properly and infuse the flavors.
- Add Chicken: Nestle the boneless skinless chicken breasts on top of the rice mixture in the slow cooker. Sprinkle the chicken with a little extra black pepper to enhance the seasoning.
- Slow Cook: Cover the slow cooker and cook on high for 2 1/2 to 3 1/2 hours until the chicken is fully cooked through and the rice has absorbed almost all of the broth. For this recipe, the cook time averaged about 3 hours on high.
- Prepare Broccoli: While the slow cooker is finishing, cook the broccoli separately. The best results come from steaming the broccoli on the stovetop, but you can also steam it in the microwave or roast it in the oven. Cooking broccoli separately helps retain its vibrant green color and texture.
- Remove and Slice Chicken: Once cooking is complete, carefully remove the chicken breasts from the slow cooker and transfer them to a cutting board. Cut the chicken into bite-sized pieces.
- Add Creamy Ingredients: To the rice and broth mixture remaining in the slow cooker, add the optional plain Greek yogurt, grated Parmesan cheese, and shredded cheddar cheese. Stir well to create a creamy, cheesy base for the casserole.

Notes
- Do not substitute the brown rice with white or other rice types, as cooking times and textures differ and may alter the final dish.
- Steaming broccoli separately preserves its bright color and crisp texture; slow cooking broccoli can result in a dull color and softer texture.
- The Greek yogurt is optional but adds extra creaminess and a slight tang to the casserole.
- Use low sodium chicken broth to control the saltiness of the dish; adjust salt to taste if using regular broth.
- Ensure chicken is fully cooked to an internal temperature of 165°F (74°C) before consuming.
