Keto roasted cauliflower with Parmesan is a tasty, creamy and cheesy side dish. Even the Picky Eater loves it! To keep it keto, I don’t use breadcrumbs in this recipe, and frankly, I don’t miss them.
It’s possible to sprinkle some almond meal on the top of this dish in addition to the Parmesan, or maybe pork panko. But really, it’s delicious with just the cheese.
How to make keto roasted cauliflower
It’s so easy! This is one of my easiest side dishes, which is why I make it so often. Scroll down to the recipe card for the detailed instructions. Here are the basic steps:

What main dish to serve with roasted cauliflower?
It’s a very versatile side dish that goes with anything! But since I make it in a 425°F oven, I like to serve it with a main dish that I can cook in the same oven. So I often serve it with one of the following main dishes:
Is this a healthy recipe?
I think it’s very healthy! It’s obviously perfect if you’re on the keto diet. But even if you’re not, cauliflower has many health benefits, and olive oil is healthy too.
As for the Parmesan, happily, current research says that for most healthy people, full-fat dairy is harmless. However, please feel free to omit it if you prefer.
What to do with the leftovers?
Leftovers keep well in the fridge for 3-4 days in a sealed container. Reheat them gently in the microwave on 50% power prior to serving.
