Recipe FAQs

Can I use a different oil than coconut oil?

Yes, absolutely. But, try to find an oil that has a high smoking point. Check out my article on the safest cooking oils.

Can I use this method to cook other types of frozen vegetables?

Yes, you can! This method works great for frozen cauliflower florets with no changes to the temperature or cooking time. For other vegetables, though, you might need to increase or decrease the cooking time to prevent the veggies from burning.
