Keto Mashed Cauliflower

This rich and creamy keto mashed cauliflower is delightfully delicious and is a great alternative to regular mashed potatoes. It is made with roasted cauliflower and sour cream and contains just 6g net carbs!

If you’re on the keto diet and you need a low carb alternative to traditional mashed potatoes, you've come to the right place. This creamy keto mashed cauliflower recipe is the perfect mashed potato substitute and tastes so close to the real thing!

This recipe is made by roasting the cauliflower first before blending, which greatly enhances the texture and also reduces the strong cauliflower taste. Roasting also helps preserve the natural flavors of cauliflower and brings out its nutty flavor.

The final texture is close to that of mashed potatoes, and it keeps well in the fridge for 2-3 days while retaining its firm consistency.

🧾 Ingredients used

You only need a few simple ingredients for this easy mashed cauliflower recipe.

• Cauliflower: It’s best to use fresh cauliflower than frozen because frozen cauliflower might be too soft after it is thawed. I use a whole head of cauliflower, but you can also use chopped florets.
• Unsalted butter: I prefer to use unsalted because that way, I can control the level of saltiness in the dish.
• Sour cream: I love to use sour cream because it adds enough moisture to the cauliflower mash without thinning it. It also adds a tangy taste and improves the texture of the overall dish. The result is a rich, buttery texture that absolutely melts in your mouth!
• Spices: salt, black pepper, and cayenne pepper.
• Olive oil / Olive oil spray: this helps improve the texture of the mashed cauliflower.

🔪 How To Make This Recipe

Here's how to make this keto mashed potatoes recipe.

• Start by preheating your oven to 450 F. Wash and pat dry the cauliflower.
• Cut the cauliflower into medium-sized florets and spread it out on a baking tray lined with foil paper. Add a tablespoon of olive oil and add a dash of salt and cayenne pepper.
• If you have an olive oil spray, it’s easier to use this; if not, a drizzle of olive oil will do. You also don’t have to add a lot of salt and pepper here, you only need a bit to bring out the flavor while roasting. You will have a chance to add some more when blending the cauliflower.
• Mix it all together until the cauliflower is well-coated. Place the cauliflower florets on a baking sheet and roast in the oven for 20 minutes or till the cauliflower is slightly crispy.
• For the next step, you can use a regular blender, food processor, or hand immersion blender. I prefer to use a regular high-powered blender as I want the cauliflower to be completely pureed and not leave any lumps behind. If you're up to it, you can also use a potato masher.
• Put the cauliflower in a blender and add the butter, olive oil, and half of the sour cream.
• I only put in half of the sour cream first because I want to be able to fully control how I would like the texture to be. You might only need half and be happy with the texture the way it is, or you might need more.
• Blend till completely pureed and check the consistency if it’s to your liking. Add more sour cream if you desire and blend again. Pour the cauliflower puree into a bowl, add the salt and pepper, and mix together.
• You can garnish with parsley, chives, parmesan cheese, or more butter. The cauliflower mash with sour cream is ready to serve!

🥫 Storing And Reheating

You can store this creamy mashed cauliflower in the fridge for 3-4 days in an airtight container to maintain its freshness. Reheat in the microwave or on the stove with a little water.

💭 Tips And Variations

• Cayenne pepper added is just a dash, so it gives a very mild heat to this keto cauliflower mash recipe. You can replace it with smoked paprika or black pepper or omit it entirely. It’s up to you.
• If the butter is at room temperature, you don’t have to melt it, but if it’s rock-solid, you should melt it a bit first.
• You can make this recipe even creamier by adding a little heavy cream or coconut cream.
• Always start with half of the sour cream and slowly add a little bit till you have reached your desired consistency.
• Add your favorite spices like garlic powder, onion powder, or your favorite herbs.
