Try this Instant Pot Cauliflower Mashed Potatoes if you want a light and healthy replacement for normal mashed potatoes. The dish is comforting, savory, and cooks quickly in the pressure cooker, so you can have a good meal without all the carbs.
Instant Pot Cauliflower Mashed Potatoes is a way to make mashed potatoes by combining cauliflower and potatoes in an Instant Pot. Switching traditional mashed potatoes for Cauliflower Mashed Potatoes with an Instant Pot is healthier because of the cauliflower.
Although this mash feels and tastes like regular mashed potatoes, it contains many fewer carbs and calories. I love how the Instant Pot thoroughly cooks the cauliflower in minutes with steam, which makes it easy to blend into silky mashed potatoes.
I First Made Instant Pot Mashed Potatoes with Cauliflower
When I attempted to make cauliflower mashed potatoes in my Instant Pot for the first time, I wasn’t sure I wanted the outcome. I’ve used other dairy-free options for potatoes before, and they didn’t work as well.
But the dish shocked me because it was both rich in flavor and smooth, and didn’t seem like any sort of compromise. I always serve this when I roast chicken, prepare a holiday meal, or want a quick and comforting dinner.
Prep Time: 10 minutes
Cook Time: 5 minutes (plus pressure build/release)
Total Time: 20–25 minutes
Servings: 4
Calories: ~120 per serving (without cheese or toppings)
Ingredients
1 large head of cauliflower (cut into florets)
3 cloves garlic (peeled)
1/3 cup low-sodium chicken broth or water
2 tablespoons unsalted butter
1/4 cup sour cream or plain Greek yogurt
Salt and pepper, to taste
Optional: 1/4 cup grated Parmesan cheese
Optional toppings: chopped chives, crispy bacon bits, or melted butter
Step-by-Step Instructions
1. Cut the Cauliflower into small pieces.
Clean the cauliflower head and split it into bite-size pieces. As a result, food is evenly cooked inside the Instant Pot. The garlic should be removed from its skin and added to cook with the cauliflower, so it adds flavor.
2. Pressure Cook
Add the cauliflower florets and garlic cloves inside the Instant Pot. Jus de poulet or simply water is enough; pour it in. Put on the lid and change the valve to Sealing.
Press the Manual/Pressure Cook button and cook under high pressure for 5 minutes.
3. Quick Release
When the timer is done, close the Oven Off button and open the door, always ensure it is open during the roasting process, so that the steam is released. When you hear the pin drop, be careful when you open the lid.
If possible, drain any added or leftover liquid. Extra moisture might turn your mash into a liquid.
4. Blend the Ice or Mash the Ice
When the cauliflower and garlic are cooked, stir in the butter, sour cream (or Greek yogurt), salt, and pepper.
If you want a chunky texture, use a potato masher to mix the ingredients until everything is well mixed.
If you want your mash to be smooth and creamy, try using an immersion blender or put the ingredients in a food processor or blender.
5. You May Add Optional Ingredients
Round out the taste by adding grated Parmesan cheese or roasted garlic to your sauce. Add salt or pepper if the taste is not right.

Guidelines to Help You Move
Cook the cauliflower for a short time, or it may release too much water. Don’t vary from the pressure cook time given in the recipe.
Get rid of extra water: Take out any excess liquid after the potatoes are cooked to keep the mashed potatoes from being too soft.
Just blend enough: Using a blender, mix the components lightly to stop them from becoming gummy.
For a tasty upgrade, garlic, Parmesan cheese, rosemary, or thyme are good additions.
