How do you cook cauliflower to taste like mashed potatoes?

The secret to making cauliflower taste like potatoes is in the cooking method.

You focus on steaming the cauliflower until it becomes tender, but retaining a crisp bite – similar to al dente pasta.

After this step you mash them with butter and put them into the oven for 5 minutes to give them a golden color and crispy texture.

Finally, you add a combination of your favorite mash-ins resulting in delicious & creamy keto mashed cauliflower that tastes just like potatoes.

If you have leftover you have the option to make cauliflower parmesan fritters that are just as delicious.

Mashed cauliflower Ingredients you’ll need

– Cauliflower: You will want to use fresh cauliflower in this recipe. If purchased frozen, make sure to thaw and dry before mashing it.

– Heavy cream: In order to get a luscious and creamy mash, you need to use fresh heavy cream instead of milk.

– Butter: Salted or unsalted, your choice. This adds smoothes and tons of flavor. I use my garlic herb butter recipe to take it to the next level.

– Parmesan cheese: You can use fresh, shaved, or shredded parmesan cheese. Freshly grated is the best option. I love how it adds tons of flavor, saltines and nuttiness to the mashed cauliflower.

Is Cauliflower Keto?

Yes, cauliflower is keto-friendly. It is low in carbs and high in fiber, which makes it a great option for those on the keto diet. 1 cup of cauliflower has only 5 grams of carbs. Cauliflower is the perfect vegetable to substitute for higher carb foods such as potatoes and rice.
