How to make cauliflower mash

If you don’t have an Instant Pot or pressure cooker, you can still make these keto cauliflower mashed potatoes! Below are all of the different ways. Simply follow the stove top or microwave directions below.

Instant Pot Directions – Instant Pot Cauliflower Mash

1. First wash cauliflower and then cut it into florets. Place a trivet or steamer basket (this silicone steamer trivet works best!) into the bottom of the instant pot. Add 1 cup of water. Next add the cauliflower florets on top of the trivet. Place top on the Instant Pot and make sure knob is set to sealed. Then hit “Manual” “High Pressure” and then set time for 1 minute.
2. Once cauliflower has been cooked for 1 minute on high pressure perform a “quick pressure release.” Once all of the pressure has been release carefully remove the Instant Pot lid. Remove the cauliflower and the trivet, and drain out the water. Return the cauliflower to the steel Instant Pot.
3. Next, add in heavy whipping cream, butter, salt, black pepper, and garlic powder.
4. With a hand mixer, mix until well combined. If you don’t have a hand mixer you can use a potato masher or immersion blender.
5. OPTIONAL – add your favorite cheese to make this a cheesy mashed cauliflower. I find that it improves the texture! Simply add the cheese and mix well with a spatula or hand mixer. If the cauliflower isn’t hot enough to melt the cheese, simply put it on “sauté” mode and the cheese will melt quickly.
6. Make sure to stir continuously while on sauté mode because it gets hot quick and you don’t want to burn the bottom!
7. Portion into a serving dish and enjoy!

RECIPE NOTES: Add your favorite toppings like sour cream/greek yogurt, parmesan cheese, bacon, chives, green onions, cream cheese, and/or butter to make it loaded!

Stove Top Directions

First wash cauliflower and then cut it into florets. In a saucepan, fill with water up to ½ inch. Cook on high heat until boiling. Add cauliflower.

Next, cover the pan and cook for 8-9 minutes. Cauliflower should be super tender. Drain away water. Add cauliflower back to saucepan.

Then reduce heat to low. Add in heavy whipping cream, butter, salt, black pepper, and garlic powder. Mix until well combined. Top with more butter.

Microwave Directions

First wash cauliflower and then cut it into florets. Add florets to a glass microwave safe container and add 2 tbsp of water. Cover with plastic wrap or a microwave safe lid.

Then, microwave for 8-9 minutes on full power. Cauliflower should be super tender. Drain away water. Add cauliflower to a large bowl.

Next, add in heavy whipping cream, butter, salt, black pepper, and garlic powder. Mix until well combined. Top with more butter.
