Ingredients for Keto Chicken and Broccoli Casserole
- 2 cups cooked chicken, shredded
 - 4 cups broccoli florets, fresh or frozen
 - 1 cup packed shredded cheddar cheese
 - 1 cup heavy cream
 - 1/2 cup cream cheese, softened
 - 1 teaspoon garlic powder
 - 1 teaspoon onion powder
 - Salt to taste
 - Pepper to taste
 
How to Prepare Keto Chicken and Broccoli Casserole
Preheat the Oven
First things first, you’ll want to preheat your oven to 350°F (175°C). This step is crucial because it ensures that your casserole cooks evenly from the moment you pop it in. Trust me, there’s nothing worse than a dish that’s bubbly on the outside but cold in the middle!
Combine Ingredients
In a large mixing bowl, it’s time to bring all those delicious ingredients together! Start by adding your shredded chicken and broccoli florets. Then, toss in the shredded cheddar cheese, heavy cream, softened cream cheese, garlic powder, onion powder, and a sprinkle of salt and pepper. Now, mix everything until it’s nicely combined—don’t be shy! You want every bite to be packed with that creamy, cheesy goodness.
Transfer and Bake
Once you’ve got everything mixed up, transfer that glorious mixture into a greased baking dish. I usually use a 9×13 inch dish, but feel free to use whatever you have on hand! Now, it’s time to bake. Pop it in the oven and let it bake for about 25-30 minutes. Keep an eye on it; you’re looking for that beautiful bubbly and golden top that’s going to make your kitchen smell heavenly!
Cooling and Serving
When the timer goes off, take the casserole out and let it cool for a few minutes before diving in. I know, it’s tempting to dig right in, but letting it sit for just a bit helps everything settle and makes serving a breeze. Then, scoop it out, and enjoy the creamy, cheesy flavor in every bite!

Tips for Success
To make your keto chicken and broccoli casserole truly shine, I’ve got a few pro tips that I swear by!
- Adjust the Seasonings: Don’t be afraid to taste and tweak! If you love garlic, throw in an extra pinch of garlic powder. Or maybe some red pepper flakes for a bit of heat? It’s all about what flavors you enjoy!
 - Add More Veggies: Get creative with your veggies! You can easily toss in some chopped bell peppers, spinach, or even cauliflower rice for a fun twist. Just make sure to keep it low-carb.
 - Cheese Variety: While cheddar is a classic, mixing in other cheeses like mozzarella or pepper jack can add a whole new dimension of flavor. Experiment and find your perfect cheesy combo!
 - Make It Ahead: This casserole is great for meal prep! You can assemble it a day ahead and pop it in the oven when you’re ready to eat. Just be sure to adjust your baking time slightly if it’s coming straight from the fridge.
 - Leftover Magic: If you have leftovers (which I doubt will happen!), they taste even better the next day! Just reheat in the oven for a few minutes to bring back that bubbly goodness.
 
With these tips, you’ll be well on your way to making the most scrumptious keto chicken and broccoli casserole that everyone will rave about!

Frequently Asked Questions
I’ve had a few questions come up about my keto chicken and broccoli casserole, so I thought I’d tackle them here! If you’re curious about anything else, feel free to ask!
Can I use fresh broccoli instead of frozen?
Absolutely! Fresh broccoli florets work wonderfully in this casserole. Just make sure to chop them into bite-sized pieces so they cook evenly. If you prefer that fresh crunch, go for it!
Can I make this casserole dairy-free?
Yes, you can! Substitute the heavy cream and cream cheese with coconut cream and a dairy-free cheese alternative. Just keep in mind that the flavor will change slightly, but it’ll still be delicious!
How can I reheat leftovers?
The best way to reheat your keto chicken and broccoli casserole is in the oven at 350°F (175°C) for about 15-20 minutes, or until it’s heated through. You can cover it with foil to prevent it from drying out!
Can I freeze the casserole before baking?

What can I serve with this casserole?
This casserole makes a hearty main dish all on its own, but if you want to add a side, I recommend a simple green salad or some roasted low-carb vegetables. They complement the flavors perfectly!
Storage & Reheating Instructions
Now, let’s talk about what to do with any leftovers of this fabulous keto chicken and broccoli casserole—if there are any! But just in case, you can store your leftover goodness in an airtight container in the refrigerator for up to 3 days. I find that it tastes even better the next day as the flavors really meld together!
When it comes to reheating, the oven is your best bet for keeping that creamy texture and cheesy goodness intact. Preheat your oven to 350°F (175°C), then place your casserole in a baking dish and cover it with foil to prevent it from drying out. Heat for about 15-20 minutes or until it’s warmed through. If you’re in a hurry, you can also use the microwave. Just pop a serving on a microwave-safe plate, cover it loosely, and heat in short intervals, stirring in between to ensure even warming.
Whichever method you choose, just know that this casserole is a delightful dish that holds up beautifully, so you can enjoy its comforting flavors even after the first serving!
