Why YOU will love this recipe
Ingredients
Find the full ingredient list, with measurements, in the recipe card below.
- Broccoli + cauliflower florets – You can use either fresh broccoli and fresh cauliflower or frozen.
- Cream cheese – Based on my firsthand experience, this is all you need to create a creamy sauce. Forget the canned soup!
- Shredded cheese – We like using marble cheddar cheese but sharp cheddar cheese, parmesan, gouda, gruyere, and mozzarella cheeses all work well too.
- Garlic powder – This adds a punch of flavor to the sauce. You could also substitute onion powder.
- Fine sea salt – A pinch of salt is essential to bring out the flavors of your ingredients.
- Black pepper – The slightly spicy flavor helps to balance the creaminess.
Equipment
- Saucepan – For steaming the vegetables.
- Mixing bowl – Only one large mixing bowl is needed.
- Spatula or spoon – We love using these little spatulas for stirring. They are one of our favorite and most used kitchen tools.
- Casserole dish – Use an 8×8 or 9×9 ceramic baking dish.
Ideal for making and sharing casseroles, roasted meat, lasagna, brownies, and desserts. Bake, serve, store, and reheat all in one dish.

Step 1
First, start by heating the oven to 375 and lightly greasing your casserole dish.
Step 2
Then, add about 2 inches of water to the large pot, set it over medium-high heat, and bring the water to a quick boil. Once the water is bubbling, add the cauliflower and broccoli florets.
Let them cook for 2-3 minutes until they have softened and are easily pierced by a fork.
Drain the water and set the veggies aside.
Step 3
Next, in the mixing bowl, stir together the cream cheese with the seasonings.
Once that is combined sprinkle in half a cup of shredded cheese.
Step 4
Then, add the steamed veggies to the bowl and stir to coat them with the cream cheese mixture.
The warm vegetables will create a delicious cheese sauce from the melting cream cheese.
Step 5
Next, pour the mixture into the prepared baking dish.
Spread it out evenly.
Step 5
Then, sprinkle on the remaining cheese on top.
Add an even layer of the shredded cheese over the broccoli and cauliflower mixture.
Step 6
Finally, place the dish in the preheated oven.
Bake for 15 minutes until the mixture is bubbling.
Expert tip! Go the extra mile and turn on the broiler for 2-3 minutes to add depth and texture with a few crispy, browned bits of cheese on top. This is easily my favorite thing about cheesy casseroles.

Made this for my vegetarian kids on Thanksgiving. I added a little milk and extra cheese. My broccoli and cauliflower had cooled so add a little milk to thin so cheese would coat them. Was a big hit. I myself do not like broccoli and only eat cauliflower when raw. But the kis all loved it.
Thanks Faye! I love that the kids approved.
I’ve had cheesy broccoli before, but never broccoli combined with cauliflower in a creamy dish. But my youngest LOVES cauliflower and we purchased two big Costco-sized bags of both veggies this weekend, so we gave this a try. So much YUM!
