Keto Hash Browns FAQs
How Can I Make Sure My Hash Browns are Crispy?
There are a couple easy tricks to help make sure that your hash browns end up crispy:
- Make sure your cauliflower rice isn't overly wet. If it has a lot of moisture, put it in a fine mesh sieve so you can press out any excess liquid. Alternatively, you can spread it out onto a paper towel to absorb the liquid.
- Don't forget to spray the baking pan and the tops of the hash browns with olive oil.
- Cooking these keto cauliflower hash browns at a high temperature (400F in this case), helps yield crispy hash browns. The bottoms get nice and crispy!
- If you want the tops crispy and brown too, you can broil them quickly. Stay with it because hash browns can burn fast under the broiler.
What if I Don’t Have Leftover Cauliflower Rice?
If you don't have leftover cauliflower rice, you can always make a batch if you have time. I have a step-by-step guide on how to make cauliflower rice starting with a whole cauliflower. You won't believe how easy it is!
But no worries if you don't have time to make it from scratch! You can buy cauliflower rice at the grocery store; look for it in the frozen section or in the fresh produce area.
If you buy frozen cauliflower rice, thaw it first and then cook it for 3 minutes either in the microwave or on the stovetop. If you buy fresh cauliflower rice, cook it for 3 to 4 minutes in the microwave or on the stovetop.
Pro Tip: To make this keto hash browns recipe, you want the cauliflower rice to be tender, but not waterlogged or mushy.
