Why You'll Keep Making This
A creamy, low-carb alternative to traditional mashed potatoes. It’s quick to make and packed with flavor from the garlic. Plus, using the Instant Pot® makes the cauliflower perfectly tender every time.
Cooking Tips You Should Know
- Use fresh garlic for the best flavor.
- Be careful not to overcook the cauliflower to avoid a mushy texture.
- For extra creaminess, add a splash of milk or a dollop of sour cream before mashing.
Directions
Turn on your Instant Pot to the sauté setting. Melt the butter and toss in the garlic, cooking it just until you can smell that lovely aroma, about 30 seconds. Add the cauliflower and give it a good stir so it’s coated in butter and begins to soften, which should take around 5 minutes. Pour in the broth, then close and lock the lid. Set the pot to high pressure and cook for 5 minutes, allowing it some time to come up to pressure first. Once the cooking time is up, let the pressure release naturally for about 3 minutes, then carefully switch to quick release to let out any remaining steam. Open the lid and mash the cauliflower right in the pot using a potato masher or an immersion blender. Stir in the Parmesan cheese and season with salt and pepper to taste.
Best Ways To Serve
Serve as a side dish alongside roasted chicken, grilled steak, or baked fish. It also pairs well with sautéed greens or a fresh salad to balance the meal.
Leftover Care Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stovetop, adding a little milk if it feels dry.
Frequently Asked Questions
Can I use frozen cauliflower instead of fresh?
Yes, you can use frozen cauliflower, but reduce the pressure cooking time to 3 minutes to avoid overcooking.
How can I make this recipe dairy-free?
Substitute butter with olive oil or a dairy-free margarine and omit the Parmesan or use a dairy-free cheese alternative.
Is it possible to add more garlic for a stronger flavor?
Absolutely, feel free to increase the garlic to suit your taste preferences.
Can I prepare this without an Instant Pot?
Yes, you can steam the cauliflower on the stove and then mash it with butter, garlic, broth, and cheese.
How should I store leftovers and how long do they last?
Store leftovers in an airtight container in the refrigerator for up to 3 days.
What can I use instead of vegetable broth?
You can substitute with chicken broth or water if you prefer.
Can I make this recipe vegan?
Use a plant-based butter and vegan Parmesan or nutritional yeast instead of the cheese.
Will using an immersion blender make the texture too smooth?
Using an immersion blender will create a creamier texture; if you prefer chunkier mash, use a potato masher.

The mashed cauliflower came out creamy and garlicy without being too strong. It was my first try using the Instant Pot for this kind of dish, and it was surprisingly simple. My family loved swapping this out for regular mashed potatoes, which is a plus!

Served this at a small dinner party and everyone loved it. I followed the recipe exactly but added a sprinkle of chives on top for extra flavor. It had a lovely creamy texture and went perfectly with the grilled veggies and tofu we made. Definitely a keeper for my recipe box.
