Quick Instant Pot Potato Cauliflower Mash (Whole30 Paleo) – a simple and delicious 4 ingredient recipe with extra hidden veggies!  This creamy blend of potatoes and cauliflower made in the Instant Pot is sure to be a family favorite!

Mashed potatoes are a favorite in our family.  When it comes to mashed potatoes, I can polish off several helpings in one sitting and they’re most definitely my favorite part of any Thanksgiving meal.  They’re just comfort food embodied to me.

I think because my love of mashed potatoes is so strong, I haven’t been able to jump on the mashed cauliflower train just yet.  While it’s all the rage, particularly on Whole30/Paleo plans, cauli mash doesn’t quite do it for me.  Also, I’ve tried and failed miserably at converting my kids and husband to mashed cauliflower.  So to please this mashed potato-loving-family of mine, I created this potato cauliflower blend and it’s a perfectly delicious combination of the two!

This recipe has the creamy whipped texture of mashed potatoes with hidden cauliflower hanging out in the background.  If you’re trying to reduce your carb load or sneak in some extra veggies, this recipe is your answer.  It’s also kid and husband approved!

I can’t forget to mention the best part of this recipe…it’s super fast and easy to make!  I toss the potatoes and cauliflower in the Instant Pot with some broth, then mash/whip the mixture with some ghee.  It could also be made on the stovetop, I just love the Instant Pot for its quick turnaround time. 🙂

What You’ll Need

Cauliflower

Russet potatoes

Chicken Broth (see my homemade version here)

Butter or Ghee

Kosher Salt

How to Make Potato Cauliflower Mash

Begin by peeling the potatoes and chopping them. Chop the cauliflower and add it all to the Instant Pot.

Add chicken broth and salt and cook on Manual setting for 5 minutes.

Remove the veggies and add the ghee (or butter.) Whip until smooth and creamy.

Is Cauliflower Potato Mash Healthier than Regular Mashed Potatoes?

There are a couple of benefits to adding cauliflower to your mashed potatoes. One, cauliflower is nutrient dense – rich in vitamin C, folate, magnesium, B6, and a great source of fiber. It is also a low-carb food source and can be a great substitution for potatoes if carbs need to be avoided for maintaining healthy blood sugar levels, etc.

Storage & Reheating Instructions

Store any leftovers in an airtight container in the refrigerator. To reheat, place desired amount in a bowl, adding a bit of broth or butter as desired if cauliflower mash seems dry. Cover with a damp paper towel and microwave for 30-60 seconds until warm.

What to Serve with Potato Cauliflower Mash

Serve this dish as a side to any meat/protein, such as:

Rosemary Dijon Turkey Kabobs

Instant Pot Whole Chicken

Steak and Veggie Kabobs

Grilled Chicken

Instant Pot Italian Beef
