I hadn’t tried mashed cauliflower until recently. I’m a lover of mashed potatoes so it wasn’t even on my radar to mash cauliflower instead! About a year ago I discovered that cauliflower can take the place of so many less healthy alternatives. We’ve recently had cauliflower rice, cauliflower pizza crust, cauliflower tacos, and now mashed cauliflower!

An Old Favorite Reinvented

Cauliflower is one of the few vegetables that I’ve actually liked since I was little. I was a picky eater when I was little, not so much anymore!

I’ve recently been eating it a lot more in an effort to eat fewer carbs and get more veggies in my diet. I usually steam cauliflower in the Instant Pot and it’s ready and cooked to perfection in no time. The Instant Pot has made it a breeze to steam veggies like broccoli and cauliflower.

Essential Equipment

  • instant pot

Ingredients

  • 1 head cauliflower cut into florets, rinsed, and steamed, approx. 2 lbs
  • 2 tbsps butter (salted) melted
  • 4 oz cream cheese
  • ½ cup sour cream
  • ½ cup heavy whipping cream
  • ¼ tsp garlic powder
  • 1 tsp kosher salt or to taste
  • 2 cups medium cheddar cheese shredded
  • 6 slices bacon cooked and crumbled
  • 2 tbsps green onion(s) chopped

Instructions

  • Preheat your oven to 425°.

steam the Cauliflower

  • While I prefer using the Instant Pot to steam cauliflower, an Instant Pot is not required for this recipe. You may steam the cauliflower on the stove if you wish. If steaming on the stove, ensure that you steam the cauliflower until it is soft.
  • To steam the cauliflower in the Instant Pot, add 1 cup of water to the pot. Place the trivet or steamer basket inside the pot and then put the cauliflower florets in the basket.
  • Close the Instant Pot and set it to ‘Manual’ or ‘Pressure Cook’ High Pressure for 3 minutes.
  • Once cooking has completed, immediately perform a quick pressure release (QPR).
  • Once the pressure has been fully released, open the pot and then allow the cauliflower to sit in the pot while you gather the remaining ingredients.

combine the Ingredients

  • Remove the cauliflower from the Instant Pot and add it to a food processor and blend until smooth and creamy.
  • Add the butter, cream cheese, sour cream, heavy cream, garlic powder and salt to the food processor and blend until smooth.
  • Remove the bowl from the food processor base and then carefully remove the blade from bowl. Add 1 cup of shredded cheddar cheese and 4 strips of crumbled bacon to the mashed cauliflower. Mix in by hand with a spatula.
  • Spoon the mashed cauliflower mix into a 9 x 11 baking dish and spread the remaining shredded cheddar cheese and crumbled bacon evenly across the top.

Bake

  • Place the baking dish on the middle rack of your oven and bake for 20 minutes, or until the cheese is bubbly and begins to get toasty in spots.
  • Remove from the oven and garnish with the chopped scallions.
