Equipment Needed:
- Crock Pot a standard 6-quart slow cooker or a Ninja Possible Cooker Pro both work
- Ninja Everyday Possible Cooker Pro 6.5 QT
- Large Mixing Bowl
- Large Serving Spoon
- Spray Cooking Oil

Instructions:
- Grease your crockpot. Spray the inside of your crockpot well with cooking spray so nothing sticks.
Pro tip: this small step makes cleanup so much easier later. - Warm the broccoli. In a large sauté pan, add 2 cups of the chicken broth and the frozen broccoli. Cook over medium heat for about 5 minutes, just until the broccoli is thawed and the broth is hot.
Pro tip: if you are using fresh broccoli, skip this step and add the florets straight into the crockpot. - Combine everything in the crockpot. Add the rice, both cans of cream of celery soup, and the garlic powder to your crockpot. Stir in the warmed broccoli and broth from your pan, then add the remaining 1 cup of chicken broth and half of the cheddar cheese. Stir everything together well.
- Cover and cook. This step depends on your appliance, so please read closely. If you are using a fast heating multi cooker like a Ninja Possible Cooker Pro, cook on high for 1 to 1.5 hours. If you are using a standard crockpot, plan on 2.5 to 3.5 hours on high, or 4 to 5 hours on low, since standard crockpots take longer to come up to temperature and this recipe uses regular rice, not instant rice.
Pro tip: every crockpot runs a little differently, so start checking at the earliest time listed and stir. The rice is done when it is tender, and the liquid is absorbed, not a minute before. - Finish with cheese. Once the rice is fully tender, sprinkle the remaining cheddar cheese over the top. Cover for 5 to 10 more minutes, just until the cheese is melted.
Hints and Tricks:
- Make sure to spray the crockpot well to make sure nothing sticks for serving and easy cleanup.
- When adding the recipe to the crockpot, make sure to evenly distribute the mixture. This helps ensure uniform cooking and flavor throughout the casserole.
- If you’re looking for a great way to have an extra layer of flavor, a great addition would be to sauté onions, add a little garlic powder, and add them to the mixture.
Variations:
This broccoli casserole recipe can be adjusted to your family’s tastes. You can make it your own with just a few additions or changes.
- Protein boost: Stir in 2 cups of diced cooked chicken.
- Different soup: Swap the cream of celery soup for cream of mushroom or cream of chicken soup.
- Different cheese: Try sharp cheddar or a Colby jack blend instead of mild cheddar.
- Different rice: Brown rice or jasmine rice both work here, just add extra time since they take longer to soften than white rice.
- Vegetarian: Use vegetable broth in place of chicken broth.
- Extra flavor: Saute some diced onion with a little garlic powder and stir it in with the broccoli.

Storing and Reheating Leftovers
Store leftovers in an airtight container in the fridge for up to 4 days.
Reheat in the microwave with a small splash of broth or milk so the rice does not dry out.
This casserole does not freeze well. The rice turns grainy once it thaws, so I recommend making it fresh.
Frequently Asked Questions
A: Yes. A standard crockpot just heats up slower, so give it more time. Plan on 2.5 to 3.5 hours on high, or 4 to 5 hours on low, and start checking at the low end of that range.
A: Your crockpot most likely needs more time. Every crockpot runs a little differently. Cover it and cook another 30 to 45 minutes, then check again before adding more time.
A: You can, but instant rice cooks much faster than regular white rice. Cut the cook time back to about 1 to 2 hours on high so the rice does not turn mushy.
A: Yes. Skip the stovetop warming step and add the fresh florets straight into the crockpot with the broth.
