The secret to low-carb Cajun fries

Unlike traditional waffle fries and Cajun French fries—which are made with high-carb, starchy potatoes—this keto-friendly recipe contains only healthy, low-carb ingredients. You’ll use eggs, butter, cauliflower, and parmesan cheese as the base, and top it all off with Cajun spice. 

After mixing up the ingredients, you cook these savory homemade Cajun fries in a waffle maker, avoiding the messy, hot oil traditionally used for deep-fried French fries. 

Shredded cauliflower is used in place of potatoes, which gives these Cajun fries added nutrients and substantially lowers the carb count while still maintaining that crispy texture.

The Health Benefits of Cauliflower

When it comes to vegetables, cauliflower ranks at the top of the healthy food list for the keto diet.

Cauliflower is a great alternative to many favorite high-carb foods, including pizza crust, rice, potatoes, tortilla shells, and mac and cheese.

Aside from its diversity in cooking keto-friendly dishes, cauliflower is a cruciferous vegetable. This means it’s highly nutritious and low in carbs. One cup of cauliflower has just 5 grams of total carbs and 3 grams of net carbs. 

Cauliflower is loaded with essential vitamins, minerals, and electrolytes. You get 85% of your daily vitamin C requirement in just a cup of cauliflower. It’s also rich in choline, which helps support liver health and brain function.
