Keto Butter Roasted Frozen Cauliflower
This quick and easy Keto recipe is a great way to jazz up frozen cauliflower. Our simple low carb side is prepared with frozen cauliflower florets, tender white onion, garlic powder, a generous helping of butter, and finished with some parmesan cheese. This is perfect for using up any cauliflower you may have in the freezer!
Do I Need to Thaw the Cauliflower?
We have used frozen cauliflower florets for this Keto side recipe. Low carb frozen vegetables are a great option for convenience and are a good Keto staple to have on hand. The cauliflower does not need thawing before cooking and can be added directly to the oven tray frozen. You can, of course, also make the recipe with fresh cauliflower florets, adjusting the cooking times as needed.
Can I Make This Dairy-Free?
We have cooked our cauliflower florets in butter for a rich and creamy flavor and to enhance the taste of the roasted cauliflower. We have then dusted the cauliflower in grated Parmesan to serve. If you would like to make the recipe dairy-free, you can sub the butter for olive oil or coconut oil, and the grated Parmesan can be swapped for nutritional yeast. Please be sure to adjust your macros to account for any changes made to the original recipe.
