Is Cauliflower Keto? 

Cauliflower is great for keto. It’s super satisfying and filling, yet naturally low in carbs (around 5g of carbs per 100g serving). In fact, this is why you’ll often see cauliflower used as a keto substitute in recipes like cauliflower rice and cauliflower mash.

This special vegetable is also rich in a range of great vitamins and minerals, including potassium, calcium, folate and vitamin C. Cauliflower is full of fiber, too, making it an excellent choice for digestive health.

Can This Recipe Be Prepped in Advance? 

Once roasted, the parmesan cauliflower is best eaten right away. However, you can pre-slice the cauliflower florets ahead of time, if desired. 

Tips for the Best Roasted Cauliflower 

Although roasting cauliflower is pretty simple, there are definitely a few tips and tricks that will make it just that bit more extra special.

• I find that slicing the cauliflower into flat sections makes for a better roast keto cauliflower than simply breaking it up into florets. This way, the flat sides get super crispy as they cook – texture is key!
• Always be sure to line your pan with parchment paper to avoid sticking.
• Give the cauliflower a good head start in the oven before adding in the parmesan, otherwise the cheese will burn (do this only in the last 10 minutes or so).
