Are you missing potatoes? Well it’s time to discover this fantastic vegetable: turnip.
Let’s talk about turnips because, oh dear goodness, I really don’t know why I haven’t tried them before. Turnips are a root vegetable that resembles in form, taste, and texture to potatoes.
I also shared a delicious recipe for turnip fries that I’m sure you’ll enjoy.
What Do Turnips Taste Like?
Turnops are super low in carbs (compared to potatoes) and have a neutral taste.
The taste varies depending on the kind of turnips you can find if they are young or older.
Smaller turnips are tender, sweet, and crunchy. Bigger turnips are spicier and need to be cooked.
At the store, try to choose smaller turnips as the bigger ones have more of a bitter taste. Select the turnips that have smooth skin and are the size of a tennis ball.
One cup of raw turnip has about 6 grams of carbs from which 2 grams are fiber, so there are only 4 grams of net carbs. Keep in mind that the same quantity of potatoes provides 22 grams of carbs.
Turnips are also nutrient-dense and can be used in any recipe that calls for potatoes. You can make gratins, mashes, soups, and even fries.

Can you use milk instead of heavy cream?
The turnips are a little hard still, any suggestions. Would it help to cook longer than the 25 minutes or should I slice thinner?
Thanks
You have to cook them longer. It really depends on your turnips and how thick the slices are. Hope it will turn out great!
