Ingredients for Garlic Mashed Cauliflower
- Cauliflower: I use one whole head of cauliflower in this recipe, and it’s prepared just like potatoes would be. If you’re not a fan of cauliflower, broccoli is an excellent substitute.
- Garlic: Garlic adds so much flavor to this recipe! Nothing beats garlicky mashed potatoes, and these cauliflower mashed potatoes taste just like the regular version.
- Parmesan Cheese: Parmesan brings this keto side dish a delicious tang. I recommend using freshly grated parmesan instead of pre-grated or powder.
- Butter: Is it mash if there is no butter? There simply must be butter in mashed cauliflower for flavor and richness!
- Sour Cream: To make this Garlic Mashed Cauliflower really creamy, I added sour cream. I prefer it to milk or regular cream as it’s extra thick. Unlike regular mashed potatoes, cauliflower retains a lot of water which can make the Cauliflower Mashed Potatoes a little thin, especially if you add milk.
- Seasoning: Salt and pepper bring out all of the other flavors and create the perfect balance.
How to make Cauliflower Mashed Potatoes
- Cook the cauliflower: Bring a large pot of salted water to a boil. Add in cauliflower florets and boil for 10 minutes or until cauliflower is tender. Drain it and set it aside.
- Make melted garlic butter: Add butter and garlic to the pot the cauliflower was cooked in. Cook for 1-2 minutes or until the butter is melted and the garlic is slightly golden brown and fragrant.
- Add to the food processor: Add the steamed cauliflower to a food processor with the blade attachment.
- Add the rest of the ingredients and blend: Add in the garlic, sour cream, and parmesan cheese. Puree for 2-3 minutes or until the mixture is smooth, creamy, and lump-free.
Season and serve: Season with salt and pepper to taste. Serve immediately and enjoy!
Tips for Success
- Cut the cauliflower florets evenly: Before boiling them. This helps them cook consistently and faster than just boiling large pieces of cauliflower.
- Drain all of your liquid: Make sure the cauliflower is fully drained before adding it to the food processor. I let them sit in the colander for at least a minute and give them a couple of good shakes to make sure all of the water has drained.
- Don’t over-salt: Unlike potatoes, cauliflower doesn’t absorb the salt so it’s best to use less or these keto cauliflower mashed potatoes will taste too salty!
- Don’t add milk: It’ll make the cauliflower puree really liquidy. Instead, use sour cream, greek yogurt, or even cream cheese.
Storage, Freezing & Reheating
- Store: In an airtight container in the refrigerator for up to 4 days.
- Freeze: In an airtight container or freezer bag for up to 4 months. Thaw completely before reheating.
- Reheat: In a pot on the stove or in a microwave until the keto cauliflower mashed potatoes are heated through.
Frequently Asked Questions

- I don’t have a food processor. What can I use instead? A hand blender works really well for this recipe, or you could try a potato masher, but I find the texture is much better as a puree.
