Key Ingredients
Cauliflower florets are the base of this Instant Pot Mashed Cauliflower recipe. You can use the florets from one head of whole cauliflower or buy a bag of cauliflower florets.
Water or broth adds the necessary moisture to cook the cauliflower.
Butter, vegan butter, or ghee adds fat and creaminess with no carbs.
Salt and pepper add flavor.
Recipe Steps
Making this recipe is actually really easy, especially using the Instant Pot pressure cooker. You can also use the stovetop but I find that the Instant Pot is a one-pot solution that is super efficient and fast. Let me show you the steps.
Step One
Grab a large cauliflower and cut it into florets.
Step Two
Place the florets and water in your Instant Pot.
Step Three
Cook on high pressure for just 2 minutes. Then, carefully release the pressure using the quick release and remove the lid.
Step Four
Add the ghee, butter, or vegan butter to the pot and use a hand-immersion blender or a potato masher to turn it into creamy, silky mashed cauliflower. Enjoy hot.
Recipes Tips & Substitutions
- Store any leftovers in an airtight container in the refrigerator for up to 4 days.
- The total cooking time includes 10 minutes for the pot to come up to pressure.
- You can use bagged cauliflower florets to save even more time.
- You can get creative with your seasonings and include garlic powder or onion powder, if you wish. I usually keep it simple with just salt and pepper.
- You can also replace the cup of water with chicken broth to add more protein, if you like.
- For keto diets, you can also top the mashed cauliflower with some parmesan cheese.
- This cauliflower puree is great topped with sliced green onions.
