Ingredients
Here’s what you’ll need to create this deliciously healthy dish:
- 2 cups cauliflower rice – Fresh or frozen works great!
- 1 lb chicken breast, cooked and shredded – I love using rotisserie chicken for an easy shortcut.
- 1 cup broccoli florets – Fresh or frozen, make sure they’re bite-sized.
- 1 cup shredded cheese (cheddar or mozzarella) – Use high-quality cheese for richer flavor; brands like Tillamook or Sargento do the trick!
- 1 cup chicken broth – Low-sodium options are the best to control salt levels.
- 1 teaspoon garlic powder – For that aromatic kick.
- 1 teaspoon onion powder – It adds depth to the flavor.
- Salt and pepper to taste – Always adjust based on your preference.
- Olive oil for greasing – Extra virgin is my go-to for its lovely flavor.
Prep Notes: If you’re using frozen cauliflower rice, make sure to thaw and drain any excess moisture. This will prevent the casserole from getting soggy. Also, allow your chicken to come to room temperature if it’s been in the fridge, as this helps it incorporate better into the mix.

Step-by-Step Instructions
Preheat the oven to 350°F (175°C). While that’s heating up, grease a baking dish with olive oil to prevent sticking.
In a large bowl, combine chicken, cauliflower rice, broccoli, half of the cheese, chicken broth, garlic powder, onion powder, salt, and pepper. Mix well until everything is evenly coated.
Pour the mixture into the prepared baking dish. Spread it out so that it cooks evenly.
Top with the remaining cheese to ensure that cheesy goodness we all crave!
Cover with foil and bake for 30 minutes. This allows the ingredients to meld together beautifully.
Remove the foil and bake for another 15 minutes until the top is golden and bubbly. The smell will have your mouth watering!
Let it cool for a few minutes before serving. This will help the casserole set up a bit and make serving easier.
Chef’s Tips:
- To avoid a dry casserole, make sure not to overcook the chicken beforehand.
- If you want a crispy top, broil for an additional minute or two, but watch it carefully so it doesn’t burn!
- Did some broccoli florets go rogue? Feel free to add in other veggies like diced bell peppers or peas!
Common Mistakes to Avoid:
- Avoid using too much moisture-laden veggies as it can make the casserole watery.
- Don’t skip the rest period after baking; it helps the flavors develop!
Expert Tips & Tricks
Storage Recommendations: Store leftovers in an airtight container in the fridge for up to 3 days. Perfect for meal prep!
Make-Ahead Instructions: You can assemble this casserole a day in advance. Just hold off on the baking until you’re ready to enjoy it—perfect for busy nights!
Troubleshooting Common Problems: If your cheese looks gooey instead of golden, your oven temperature may have been too low; try cranking it up for a few minutes next time to get that perfect melt.
Mix it Up: For variation, consider adding in herbs such as thyme or rosemary for an aromatic twist, or spice it up with a dash of chili flakes.
Thawing Tips: If frozen, thaw in the fridge overnight to ensure even cooking when you bake it.
