With Thanksgiving creeping around the corner you’re probably busy making preparations and compiling your arsenal of delicious home-cooked recipes.
Whether you’re keeping it keto, or indulging in a cheat day, these faux mashed potatoes are an absolute MUST this holiday season! They’re so creamy and delicious even your non-keto family members will approve!

Is Cauliflower Keto-Friendly?
Cauliflower is one of the most popular ketogenic vegetables. And that’s likely because of its versatility. Cauliflower has a very mild taste and can be used as a substitute for potatoes, rice, and even pizza crust.
Beyond that, cauliflower is SUPER low in carbohydrates. One cup (100 grams) of raw cauliflower contains 5 grams of carbs, 3 of which are fiber— which means, you can eat a fair amount without killing your carb count.
And the best part, cauliflower is surprisingly nutritious!

Making This Recipe Without an Instant Pot
This recipe is ridiculously quick and easy with an Instant Pot. However, if you don’t yet own this wondrous device you can always make these mashed “potatoes” old-school-style on the stovetop. All you’ll need is a saucepan with a lid, a steamer basket, and about 30 extra minutes.
Here’s How
- Place a steamer basket inside of a large saucepan.
- Fill the saucepan with about 2 inches of water (the water should barely touch the bottom of the steamer basket).
- Cut cauliflower into florets and place in the steamer basket.
- Cover pan and bring to med-high heat.
- Steam cauliflower for 20-30 minutes (or until soft).
- Drain the water and place cooked cauliflower in a food processor.
- Add butter, sour cream, rosemary, salt, and pepper.
- Pulse until desired consistency.
- Drizzle with olive oil and garnish with a sprinkle of rosemary.
